Resumo O texto apresenta e analisa as cartas privadas de João Baptista de Almeida Garrett (1799-1854) enviadas a sua filha Maria Adelaide, no período em que esta se encontrava como porcionista das Salésias, entre novembro de 1853 e 1854. Trata-se de um conjunto de 40 cartas manuscritas que permaneceram inéditas até à publicação de Correspondência Familiar (2012). Não obstante serem documentos privados de carácter inviolável, quando se lhes autoriza a publicação assumem valor histórico por reconstruírem situações da esfera familiar numa perspetiva informal raramente dada a conhecer. Num estilo direto e despretensioso, as 40 cartas são um genuíno testemunho de amorosidade paterna e um registo do investimento educativo em oitocentos, não comum em Portugal. Daí o seu significado para a literatura pedagógico-política, parca em correspondência doméstica, a que acresce o contributo para compreensão do que se afigura coerente no pensamento liberal português sob influência do romantismo: por um lado, a correlação entre ilustração e civilidade; por outro, o desnivelamento da exigência da educação em função do género. Sabendo-se que Garrett escreveu as cartas 24 anos depois da publicação do livro Da Educação (1829), pergunta-se pela confirmação da coerência ideológica na transição do plano teórico generalizado para o plano prático individualizado.

Abstract: The text presents and analyses the private letters of João Baptista de Almeida Garrett (1799-1854) sent to his daughter Maria Adelaide, during the period when she was an internal student of the Salésias, between November 1853 and 1854. It is a set of 40 handwritten letters that remained unpublished until the publication of Correspondência Familiar (2012). Although these are private documents of an inviolable nature, when they are authorised for publication they take on historical value by reconstructing situations in the family sphere from an informal perspective rarely made known. In a direct and unpretentious style, the 40 letters are a genuine testimony of paternal love and a record of educational investment in the eighteenth century, not common in Portugal. Hence its significance for the pedagogical-political literature, scarce in domestic correspondence, which adds to the contribution to the understanding of what seems coherent in the Português liberal thought under the influence of romanticism: on the one hand, the correlation between illustration and civility; on the other hand, the unevenness of the demand for education according to gender. Knowing that Garrett wrote the letters 24 years after the publication of the book Da Educação (1829), we wonder about the confirmation of the ideological coherence in the transition from the generalized theoretical plan to the individualized practical plan.

Biochars from peanut shell wastes were produced and further modified with KOH and HNO3 to efficiently remove two industrial dyes, Mordant Orange 1 and Green Malachite oxalate, in aqueous systems. The materials were characterized through elemental analysis, N2 adsorption isotherms, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and the determination of the point of zero charge, pHPZC. The basic and, particularly, the acid treatments increased the specific surface area by 15 and 43%, respectively, and the pHPZC shifted from 6.2 to 9.1 or 3.3 upon treatments with KOH or HNO3. These modifications impacted the adsorption behavior of the dyes; in the case of Mordant Orange 1, the adsorption capacity increased 2 and 4 times, respectively, when compared with the parent biochar. These results show that the performance of biochars can improve substantially through simple modifications using acid or basic treatments that not only increase the specific surface area but also modify adsorbent/adsorbate interactions.

RESUMO A síndrome Shprintzen-Goldberg é uma entidade muito rara descrita em 75 pessoas, caracterizada por craniossinostose e habitus marfanóide. O objetivo deste estudo é apresentar o relato de um caso clínico de uma criança brasileira de 6 anos com síndrome da craniossinostose de Shprintzen-Goldberg, apresentando as características craniofaciais e orais e seu manejo clínico, comparando com a literatura. O paciente apresentava deficiência intelectual, craniossinostose, proptose ocular, orelhas anômalas de implantação baixa e outros defeitos esqueléticos e do tecido conjuntivo. As características orais incluíram má oclusão, micrognatia, pseudo fenda palatina, atividade de cárie e controle ineficiente do biofilme. O tratamento foi iniciado com orientações sobre alimentos cariogênicos, higiene oral e indicação de suspensão do uso de mamadeira. Em seguida, as lesões cariosas foram restauradas com resina composta e o paciente encaminhado para cirurgia ortopédica, tratamento ortodôntico, fonoaudiologia e nutricionista. O paciente foi acompanhado periodicamente por 5 anos. Este relato de caso enfatiza a importância do conhecimento das características craniofaciais e orais para o diagnóstico e manejo clínico de uma criança do sexo feminino com síndrome de craniossinostose de Shprintzen-Goldberg rara, destacando a necessidade de cuidados com a saúde bucal em indivíduos com deficiência intelectual.

ABSTRACT Shprintzen-Goldberg craniosynostosis syndrome, characterized by craniosynostosis and marfanoid habitus, is a very rare entity described in 75 individuals worldwide. This study aimed to present a case report of a 6-year-old female Brazilian child with Shprintzen-Goldberg’s craniosynostosis syndrome. We described the craniofacial and oral characteristics and its clinical management, comparing to the existing literature. The patient presented with intellectual disability, craniosynostosis, ocular proptosis, low-set anomalous ears, and other skeletal and connective tissue defects. Oral features included malocclusion, micrognathia, pseudo-cleft palate, dental caries, and inefficient biofilm control. The treatment started with guidance on cariogenic foods, oral hygiene, and an indication to discontinue bottle feeding. Subsequently, the carious lesions were restored with composite resins, and the patient was referred for orthopedic surgery, orthodontic treatment, speech therapy, and nutritional counseling. The patient was followed for 5 years. This case report emphasizes the importance of knowing the craniofacial and oral characteristics for the diagnosis and clinical management of a female child with a rare Shprintzen-Goldberg’s craniosynostosis syndrome. The case also highlights the need for oral health care in individuals with intellectual disabilities.

Abstract Introduction General anesthesia is commonly used in the dental treatment of people with disabilities, anxious or difficult behavior, who need complex and/or extensive treatments. Objective The aim of this study was to evaluate the epidemiological profile of patients with disabilities undergoing dental treatment under general anesthesia by the team of the Dental Unit for Patients with Special Needs of the Federal University of Sergipe. Material and method Through the analysis of 371 dental records of patients assisted between August 2002 and March 2019. Result The analysis showed that 56.1% of patients were male, the most prevalent age group was 11-20 years, and the most frequent medical conditions were intellectual disability, followed by multiple disabilities. Relative to dental procedures, in 94.1% of the patients, it was observed that 4,056 dental extractions were performed and in 52.3% of patients, 1,156 restorations were performed. In 30.2% of patients, total multiple extractions were performed. Radiographic examination was performed in 51.8% of patients. As regards the origin of patients, 58.8% were from municipalities in the state, other than the capital. Return to the service for follow-up and prevention was observed in 38.5% of patients. Conclusion There is great need for early dental intervention, with specific preventive actions for this group of patients, focusing on those from interior regions of the state.

RESUMO Entre 2015 e 2017, houve um grande aumento no número de notificações de recém-nascidos com microcefalia no Brasil, principalmente na região Nordeste. Essa ocorrência foi associada ao vírus Zika, o qual foi responsável por uma síndrome caracterizada por problemas neurológicos, musculoesqueléticos, sensoriais, entre outros, denominada Síndrome Congênita do Vírus Zika. Apesar da grande repercussão mundial, poucos estudos acerca do comprometimento oral nessas crianças foram publicados. Dessa forma, este trabalho tem como objetivo propor a partir de uma revisão de literatura, um referencial de orientação para o atendimento odontológico destes indivíduos, a fim de embasar os profissionais dessa área. Observou-se que pessoas com Síndrome Congênita do Vírus Zika apresentam uma série de comorbidades sistêmicas que influenciam na sua condição oral e podem comprometer o atendimento odontológico, necessitando de cuidados especiais. Até então, nenhum protocolo clínico para o atendimento dessas crianças foi encontrado na literatura. Dessa forma esse estudo é pioneiro e de grande importância para direcionamento profissional e cuidado desses pacientes.

ABSTRACT There was a large increase in the number of newborns with microcephaly in Brazil between 2015 and 2017, mainly in the Northeast. This increase was associated with intrauterine Zika virus infection, which causes a congenital syndrome characterized by neurological, musculoskeletal, and sensory abnormalities. Despite the great worldwide repercussion, few studies about oral conditions in children with the syndrome have been published. This work aims to propose a guide for the dental care of these individuals on the basis of a literature review. Children with congenital Zika syndrome have a number of systemic comorbidities that affect their oral health and can compromise dental care. To date, no clinical protocol has been established for the dental care of children with congenital Zika syndrome. This is a pioneering study of great importance to orient dental professionals and promote the dental health of these children.

ABSTRACT Introduction: Cerebral palsy involves loss or impairment of motor function attributed to non-progressive disturbances occurring in the developing fetal or infant brain. Self-inflicted oral trauma is a recurrent parafunctional habit in individuals with cerebral palsy. Objective: Describe two treatment modes for self-inflicted oral trauma in a 6-year-old male patient with cerebral palsy over a 5-year follow-up period. Case presentation: The child had been having pain due to injuries to the mouth floor and lingual frenum regions. Initially, low-level laser therapy was applied to accelerate the healing process of the wounds. Five years later, the child started to present worse oral injuries and placement of a fixed oral appliance was proposed. Intraoral examination showed that the wounds had healed completely in response to the oral appliance. Conclusions: Different therapies may be useful to control the recurrence of self-inflicted oral injuries.

RESUMEN Introducción: La parálisis cerebral provoca una pérdida o deterioro de la función motora atribuida a trastornos no progresivos del desarrollo cerebral fetal o infantil. La lesión autoinfligida es un hábito parafuncional recurrente en personas con parálisis cerebral. Objetivo: Describir dos modalidades de tratamiento para las lesiones autoinfligidas en un niño de 6 años de edad con parálisis cerebral durante un periodo de seguimiento de 5 años. Presentación del caso: El niño presentaba dolor debido a lesiones en la región del suelo de la boca y el frenillo lingual. Inicialmente se aplicó terapia con láser de baja intensidad para acelerar el proceso de cicatrización de las heridas. Cinco años más tarde el niño empezó a presentar lesiones bucales más severas, por lo que se propuso la colocación de un dispositivo oral fijo. El examen intraoral mostró que las lesiones habían cicatrizado completamente en respuesta al dispositivo oral instalado. Conclusiones: Diferentes terapias pueden ser útiles para controlar la recurrencia de las lesiones orales autoinfligidas.

Abstract The aim of this study was to evaluate the effect of periodontal treatment on the salivary cytokine levels and clinical parameters of individuals with cerebral palsy (CP) with gingivitis. A non-randomized, clinical trial was conducted in individuals diagnosed with spastic CP. Thirty-eight individuals were enrolled in the study and were categorized according to gingival index scores between 0-1 or 2-3, assigned to groups G2 or G1, respectively. Periodontal treatment comprised oral hygiene instructions, conventional mechanical treatment and 0.12% chlorhexidine applied as an adjunct. Clinical parameters and saliva samples were collected at baseline and at the 15-day follow-up visit. Bleeding on probing and periodontal screening and recording were determined. Non-stimulated saliva samples were obtained, and the salivary flow rate, the osmolality and the levels of cytokines IL-1β, IL-6, IL-8, IL-10, TNF-α and IL-12p70 were evaluated by a cytometric bead array. The Wilcoxon test, the Mann-Whitney test, Spearman correlation analysis, Poisson regression analysis and an adjusted analysis were performed (α = 0.05). The groups differed significantly in periodontal clinical parameters at baseline and at follow-up. Salivary flow rate and osmolality were similar in both groups at both timepoints. However, TNF-α and IL-1β levels were higher in G1 than in G2 at baseline. Mechanical treatment resulted in improved clinical parameters for both groups. Furthermore, mechanical treatment resulted in a significant reduction in salivary IL-1β and IL-8 levels for both groups after treatment. Periodontal treatment performed in individuals with CP and gingivitis reduces the levels of TNF-α, IL-1β, IL-6 and IL-8.

Abstract Obesity is considered a risk factor for periodontal health due to the low- grade inflammation promoted by the increased adipose tissue. Objective: This study aimed to determine correlations and associations between gingival inflammation (Simplified Oral Hygiene Index, and Gingival Index), salivary immunoglobulin A (s-IgA), and salivary parameters (salivary flow and osmolality) in normal-weight and overweight/obese children. Material and Methods: Ninety-one children, aged 6 to 12 years old (8.6±1.9 years), were divided into two groups according to their body mass index (BMI), circumferences, skinfold measurements and body fat percentage: normal- weight group (NWG; n =50) and overweight/obese group (OG; n =41). A calibrated examiner performed the clinical examination using the Simplified Oral Hygiene Index, Gingival Index, and salivary collection. Data analysis included descriptive statistics and association tests ( p <0.05). Results: OG presented statistically higher s-IgA values compared with NWG, especially among the obese children ( p <0.05). Significant positive correlations between s-IgA and salivary osmolality in OG ( p <0.05), and between s-IgA and BMI values ( p <0.05) and body fat percentage ( p <0.05) were observed among all the children. Effect size varied from moderate for s-IgA values ( d =0.57) to large for BMI ( d =2.60). Conclusion: Gingival inflammation and salivary parameters were similar for NWG and OG; however, s-IgA presented higher values in OG, with correlations between BMI and body fat percentage.

Resumo Introdução Lesões dentárias por trauma constituem experiências angustiantes em crianças, que promovem alterações tanto físicas quanto emocionais e psicológicas. Objetivo Avaliar a prevalência de traumatismos dentários em pacientes com distúrbio neuropsicomotor e comparar a indivíduos normorreativos. Material e método Avaliaram-se 120 indivíduos, sendo 60 com alterações neuropsicomotoras (grupo de estudo) e 60 normorreativos (grupo controle), de ambos os sexos, de 2 a 15 anos de idade, assistidos na Fundação de Apoio ao Deficiente do Governo do Estado da Paraíba. Os dados foram coletados por meio de questionário estruturado e exame clínico. Foi realizada análise descritiva e inferencial (teste t-student; teste Exato de Fisher), adotando-se um nível de significância de 5%. Resultado A prevalência de traumatismos dentários observada em pacientes com distúrbio neuropsicomotor foi de 20,0%, enquanto que no grupo controle foi de 16,6% (p>0,05); no grupo controle a ocorrência foi maior no sexo masculino. Os grupos diferiram quanto ao tipo de atividade no momento do trauma (p<0,05) em relação à etiologia (p<0,05) e em relação ao local de ocorrência (p<0,05). Para ambos os grupos, os dentes mais afetados foram os incisivos centrais superiores. As fraturas de esmalte, seguidas pelas de esmalte e dentina sem exposição pulpar foram as lesões mais comuns nos dois grupos. Conclusão A prevalência de traumatismos dentários em indivíduos com alteração neuropsicomotora é similar à de indivíduos normorreativos, com maior ocorrência no sexo feminino, em fase anterior à adolescência, durante atividades de rotina.

Abstract Introduction Traumatic dental injuries are distressing experiences in children, which promote both physical, emotional and psychological changes. Objective To evaluate the prevalence of dental trauma in patients with neuropsychomotor disorder and to compare to normoreactive individuals. Material and method 120 individuals, 60 neuropsychomotor changes (study group) and 60 normorreatives (control group), of both sexes, from 2 to 15 years old, assisted in the Foundation of Support to the Disabled of the Government of the State of Paraíba. Data were collected through a structured questionnaire and clinical examination. Descriptive and inferential analysis (t-student test; Fisher's exact test) was performed, adopting a significance level of 5%. Result The prevalence of dental trauma observed in patients with neuropsychomotor disorder was 20.0%, whereas in the control group it was 16.6% (p>0.05); in the control group the occurrence was higher in males. The groups differed according to the type of activity at the moment of the trauma (p<0.05) in relation to the etiology (p<0.05), and in relation to the place of occurrence (p<0.05). For both groups, the most affected teeth were the maxillary central incisors. Enamel fractures, followed by enamel and dentin fractures without pulp exposure were the most common lesions in both groups. Conclusion The prevalence of dental trauma in individuals with neuropsychomotor alterations is similar to that of normorreative individuals, with a higher occurrence in females, in preteen phase, during routine activities.

Resumo O objetivo foi avaliar o perfil e a sobrecarga de cuidadores de crianças/adolescentes com e sem síndrome de Down. As avaliações foram realizadas por meio dos questionários sobre o perfil e a sobrecarga dos cuidadores (Burden Interview), e o perfil das crianças/adolescentes. Estes questionários foram aplicados a 168 cuidadores. Os testes Qui-quadrado, Exato de Fisher e Análise de Variância foram empregados com nível de significância fixado em α = 5%. Ambos os grupos eram compostos por 84 participantes, e os cuidadores do grupo com deficiência apresentaram porcentagem significantemente maior para o sexo feminino (p = 0,001), faixa etária de 41-60 anos (p < 0,001), não possuíam ocupação laboral (p < 0,001), baixa renda per capita (p < 0,001), baixo nível de escolaridade (p = 0,021), religião católica (p = 0,001), maiores de problemas de saúde (p < 0,001), em uso de medicação continua (p < 0,001) e com nível de sobrecarga moderada (p < 0,001). As crianças/adolescentes com deficiência necessitavam significantemente maior auxilio para a alimentação (p = 0,051), banho (p = 0,006), vestuário (p = 0,042), controle de esfíncteres (p = 0,027) e higiene íntima (p < 0,001). Os cuidadores de crianças/adolescentes com síndrome de Down apresentam sobrecarga moderada, quando comparados à cuidadores de crianças/adolescentes normoreativas.

Abstract The aim of this study was to evaluate the profile and burden of caregivers of children/adolescents with and without Down syndrome. The evaluations were performed through questionnaires about the profile and burden of the caregivers (Zarit Burden Interview) and the profile of the children/adolescents. These questionnaires were applied to 168 caregivers. The chi-square test, Fisher's exact test, and analysis of variance were used with a significance level set at a = 5%. Both groups were composed of 84 participants, and the caregivers of the disabled group had a significantly higher percentage of females (p = 0.001), those in the 41-60 age group (p < 0.001), those who had no occupation (p < 0.001), those with a low per capita income (p < 0.001), those with a low level of schooling (p = 0.021), those who were Catholic in religion (p = 0.001), those who had more health problems (p < 0.001), those who continued the use of medication (p < 0.001), and those with a moderate level of burden (p < 0.001). The children/adolescents with disabilities needed significantly more help for eating (p = 0.051), bathing (p = 0.006), dressing (p = 0.042), sphincter control (p = 0.027), and intimate hygiene (p < 0.001). The caregivers of children/adolescents with Down syndrome presented a moderate burden compared to the caregivers of normoreactive children/adolescents.

As pigmentações negras do esmalte se devem à coloração extrínseca e estão associadas com problemas estéticos. O objetivo é apresentar dois casos clínicos de crianças com pigmentações extrínsecas negras do esmalte dentário, com ênfase no tipo de tratamento e no acompanhamento. Trata-se de um paciente de 5 anos de idade que utilizava constantemente sulfato ferroso para tratamento de anemia por deficiência de ferro; e outro paciente de 12 anos de idade com diabetes mellitus tipo 1 e dermatomiosite. No primeiro caso observou-se a presença de pigmentações negras extrínsecas nos dentes decíduos e nos primeiros molares permanentes, principalmente nas superfícies lingual e vestibular na região cervical e terço médio, além de lesões de cárie incipientes nas superfícies oclusais dos molares e manchas brancas ativas nos primeiros molares permanentes. No segundo caso, havia pigmentações negras extrínsecas na região cervical das superfícies lisas dos dentes decíduos e permanentes. No primeiro caso, foi realizado tratamento para remoção das pigmentações negras e polimento dos dentes por meio de profilaxia profissional com creme dental abrasivo que contém pedra pomes microgranulada. Houve uma melhora no aspecto clínico a partir da segunda sessão e finalizado na quinta sessão. Para o caso 2, observou-se dificuldade na remoção de manchas pigmentadas na região cervical e risco de sangramento gengival. Uma vez que a criança necessitava de antibiótico profilático, optamos pelo controle diário de biofilme e não remoção pela profilaxia profissional, uma vez que o paciente não se queixava do impacto estético. Conclui-se que as pigmentações negras extrínsecas podem ser observadas facilmente em crianças, e ainda que haja um comprometimento estético, não traz danos à manutenção da saúde bucal. Cabe ressaltar que não está claro como sua presença na superfície dentária reduz a suscetibilidade à cárie. Além disso, a escolha do tratamento sempre deverá ser baseada no risco-benefício para o paciente.

Dark enamel pigments are due to extrinsic staining and associated with aesthetic problems. The objective is to present two cases of children with black extrinsic pigmentation in the tooth enamel, with emphasis on the type of treatment and monitoring. This is a 5-year-old patient of who constantly used ferrous sulfate to treat anemia by iron deficiency, and another 12-year-old patient with type 1 diabetes and dermatomyositis. In the first case, we observed the presence of black extrinsic pigments in the primary teeth and the first permanent molars, especially in the lingual and vestibular part in the cervical region and middle third, together with incipient caries lesions on the occlusal surfaces of molars and active white spots on the first permanent molars. In the second case, there were strange black pigmentation in the cervical region of the smooth surfaces of the primary and permanent teeth. In the first case, the treatment performed was to remove black pigments and polishing the teeth by means of professional prophylaxis and using an abrasive toothpaste containing micro-granules of pumice. There was an improvement in the clinical aspect from the second session and the treatment ended at the fifth session. For the second case, we observed difficulty to remove the pigmented spots in the cervical region, together with the risk of bleeding gums. When the child needed prophylactic antibiotics, we opted for the daily control of the biofilm and it was not removed by professional cleaning, because the patient did not complain about the aesthetic impact. As conclusions, the extrinsic black pigments can be easily observed in children, and despite its aesthetic effect, it does damage oral health. It should be noted that it is unclear how their presence on the tooth surface reduces susceptibility to caries or tooth decay. In addition, the choice of treatment should always be based on the relation risk-benefit for the patient.

Los pigmentos de esmalte negro se deben a la tinción extrínseca y están asociados con problemas estéticos. El objetivo es presentar dos casos clínicos de niños con pigmentaciones extrínsecas negras del esmalte dental, con énfasis en el tipo de tratamiento y el seguimiento. Se trata de un paciente de 5 años de edad, que utilizaba constantemente sulfato ferroso para el tratamiento de la anemia por deficiencia de hierro, y otro paciente de 12 años de edad con diabetes mellitus tipo 1 y dermatomiositis. En el primer caso se observó la presencia de pigmentos extrínsecos negros en los dientes primarios y los primeros molares permanentes, principalmente en la parte lingual y vestibular en la región cervical y tercio medio; además de lesiones de caries incipientes en las superficies oclusales de los molares y manchas blancas activas en los primeros molares permanentes. En el segundo caso, había pigmentaciones negras extrañas en la región cervical de las superficies lisas de los dientes primarios y permanentes. En el caso 1, se realizó el tratamiento para eliminar los pigmentos negros y el pulido de los dientes por medio de una profilaxis profesional con crema dental abrasiva que contiene microgránulos de piedra pómez. Hubo una mejora en el aspecto clínico a partir de la segunda sesión y se finalizó en la quinta sesión. Para el caso 2, se observó dificultad en la eliminación de manchas pigmentadas en la región cervical y el riesgo de sangrado de las encías. Una vez que el niño necesitaba antibióticos profilácticos, optamos por el control diario de la biopelícula y no se eliminó por la limpieza profesional, ya que el paciente no se quejaba del impacto estético. Se concluye que los pigmentos negros extrínsecos pueden observarse fácilmente en los niños, y aunque haya un efecto estético, no hace daños al mantenimiento de la salud bucal. Cabe señalar que no está claro cómo su presencia en la superficie del diente reduce susceptibilidad a la caries. Además, la elección del tratamiento siempre se debe basar en el beneficio-riesgo para el paciente.

AIM: To evaluate the influence of the classification of cerebral palsy CP on the caries experience in children and adolescents, and determine the types of teeth most affected by dental caries. METHODS: A total of 181 individuals with CP, aged 8.30±4.10 years were examined for dental caries diagnosis in primary, mixed and permanent dentitions. The sample consisted of 96 quadriplegic individuals, 56 diplegic, 18 hemiplegic and 11 with choreoathetosis. The groups were compared using Kruskal-Wallis and Chi-square tests. Univariate logistic regression models were used to identify whether age was a predictor of caries risk α=5%. RESULTS: The sample was homogeneous as regards sex and age, among patients with quadriplegia, diplegia, hemiplegia and choreoathetosis. Out of the total sample, 51.4% of the individuals were caries free. The overall mean for the dmft and DMFT indices were 1.70±3.30 and 0.70±1.60, respectively. The mean caries experience in primary, mixed and permanent dentitions did not vary significantly according to the CP classification p>0.05. Child´s age was a predictor for dental caries experience p<0.05. CONCLUSIONS: The CP classification did not influence on caries experience, and the teeth most affected by dental caries were the primary and first permanent molars.

INTRODUÇÃO: Em indivíduos com paralisia cerebral, ocorre redução do fluxo salivar, o que pode predispor à hipomineralização do esmalte e à cárie dentária. OBJETIVO: Comparar a microdureza do esmalte de dentes decíduos anteriores e posteriores de crianças com paralisia cerebral (PC) e crianças normorreativas (NR). MATERIAL E MÉTODO: Foram utilizados 58 dentes decíduos esfoliados/extraídos, que foram distribuídos em quatro grupos: (A) anteriores de PC (n=14); (B) anteriores de NR (n=16); (C) posteriores de PC (n=14), e (D) posteriores de NR (n=14). Os dentes foram seccionados, incluídos em resina acrílica, lixados e polidos. A análise da microdureza longitudinal foi realizada em microdurômetro com endentador do tipo Knoop, com carga estática de 25 g/f e tempo de 5 segundos. Foram realizadas três fileiras de 12 endentações, distanciadas entre si em 100 mm, com profundidade entre 10 e 180 mm. Foram obtidas as médias de cada profundidade para cada dente e, posteriormente, as médias de cada profundidade para cada grupo avaliado. O teste estatístico empregado foi o de Mann-Whitney (α=5%). RESULTADO: As médias de microdureza foram 253,5 ± 55,3 (A), 247,6 ± 45,7 (B), 284,4 ± 68,7 (C) e 252,2 ± 53,8 (D). Não houve diferença estatisticamente significante entre os grupos A e B e os grupos C e D, para cada profundidade e para a média global (p>0,05). CONCLUSÃO: Pôde-se concluir que a microdureza de esmalte de dentes decíduos anteriores e posteriores de crianças com PC foi semelhante à microdureza de esmalte de dentes decíduos de crianças normorreativas.

INTRODUCTION: Cerebral palsy subjects present reduced salivary flow, which may predispose to enamel hypomineralization and dental caries. AIM: To compare the enamel microhardness of anterior and posterior primary teeth of normorreactive children (NR) and children with cerebral palsy (CP). MATERIAL AND METHOD: The sample was consisted of 58 exfoliated/extracted primary teeth distributed into 4 groups: (A) anterior teeth of CP (n= 14), (B) anterior teeth of NR (n=16),(C) posterior teeth of CP (n=14) and (D) posterior teeth of NR (n=14). The teeth were hemisectioned, embedded in acrylic resin, grounded and polished. The longitudinal microhardness analysis was carried out in a microdurometer with a Knoop indenter with a 25-gram load for 5 seconds. Three rows of 12 indentations were made from the outer surface from 10 to 180 mm. The rows were spaced 100 mm from each other. The values of the three measurements at each distance were averaged for each tooth and, afterwards, for each group. The non-parametric statistical test used was the Mann-Whitney U (α=5%). RESULT: The microhardness means data were 253.5 ± 55.3 (A), 247.6 ± 45.7 (B), 284.4 ± 68.7 (C) and 252.2 ± 53.8 (D).There was no significant difference between the groups A and B, as well as groups C and D for each distance and global average (p>0.05). CONCLUSION: It can be concluded that the enamel microhardness of anterior and posterior primary teeth of cerebral palsy children was similar to the normorreactive children.

AIM: To investigate whether oral motor performance is determinant for the hydration status and the effect of a supplemental oral fluid supply on salivary osmolality.METHODS: The sample consisted of 99 children with cerebral palsy aged 6 to 13 years old. In this study, children participated in 2-day evaluations: 1st day - baseline: saliva collection, caries experience and oral motor performance evaluations; and 2nd day: saliva collection after supplemental fluid supply. Prior to each evaluation, the participants were trained for saliva collection. Unstimulated whole saliva was collected using cotton roll at baseline, with the amount of fluid usually offered by caregivers, and 48 h after baseline, with as much as twice the normal daily fluid intake previously offered. Salivary osmolality was measured using a freezing point depression osmometer. Caries experience index for decayed, missed and filled teeth (DMFT) was evaluated. According to the Oral Motor Assessment Scale, the children were classified into subfunctional or functional groups. Chi-square, Student's t test and Pearson's correlation coefficient were used.RESULTS:The subfunctional group presented a higher percentage of quadriplegic children (p<0.001), with significantly higher values for caries experience (p<0.001) and salivary osmolality (p<0.001), which did not diminish when supplemental fluid supply was offered, compared with the functional group (p=0.001).CONCLUSIONS: The effectiveness of oral motor performance plays an important role in the hydration status of children with cerebral palsy and those with worse oral motor performance may be at higher risk of oral diseases.
