RESUMO Traumatismos dentários podem acontecer em qualquer fase da vida, entretanto, é muito comum em crianças na idade pré-escolar e escolar. As lesões de luxação na dentição decídua são as lesões dentárias traumáticas mais comumente descritas na literatura. O deslocamento dentário na dentição decídua é favorecido devido à maior porosidade e resiliência do osso alveolar. Através do relato de caso clínico, o artigo apresenta a conduta clínica realizada diante um trauma de luxação lateral com acometimento de fratura de tábua óssea vestibular no intuito de auxiliar a prática clínica de cirurgiões-dentistas que atendem crianças. O tratamento realizado neste caso clínico levou em consideração a magnitude do deslocamento, o grau de desenvolvimento do elemento dentário e sua relação com o germe do permanente, o tempo de procura após o trauma e o grau de cooperação da criança diante o tratamento sugerido. O tratamento não envolve apenas a intervenção de urgência, o paciente deve passar por um acompanhamento e controle clínico radiográfico depois de 30, 60 e 120 dias e anualmente até a Esfoliação do dente decíduo. Pôde-se verificar que foi restabelecida a saúde da criança no aspecto estético e funcional. vida entretanto préescolar pré escolar literatura alveolar cirurgiõesdentistas cirurgiões dentistas permanente sugerido urgência 30 6 12 decíduo Pôdese Pôde se funcional 3 1

ABSTRACT Dental trauma can happen at any stage of life; however, it is very common in preschool and school aged children. Dislocation injuries in the primary dentition are the most commonly described traumatic dental injuries in the literature. Tooth displacement in the primary dentition is favored due to the greater porosity and resilience of the alveolar bone. Through the study of a clinical case, this article presents the clinical conduct performed in the case of trauma of lateral dislocation with involvement of a fracture of the buccal bone plate in order to assist the clinical practice of dentists who care for children. The treatment carried out in this clinical case study took into account the magnitude of the displacement, the degree of development of the tooth and its relationship with the permanent germ, the length of time since the trauma, and the degree of cooperation of the child in the face of the suggested treatment. This treatment does not only involve emergency intervention; the patient must undergo a radiographic clinical follow-up and control after 30, 60 and 120 days, as well as annually, until the Exfoliation of the deciduous tooth. The child’s health was restored aesthetically and functionally. life however children literature germ intervention followup follow up 30 6 12 days annually childs s functionally 3 1

RESUMO O objetivo deste estudo é descrever o efeito de um preenchedor de ácido hialurônico em lábios finos, avaliando a distribuição do material e sua relação com a vascularização tecidual bem como a efetividade da estruturação da forma e volume tecidual através dos resultados imediatos e sua longevidade após o período de 10 meses. Participou deste estudo uma mulher caucasiana, 40 anos de idade, com queixa de lábios finos, que nunca havia feito qualquer procedimento clínico ou cirúrgico nos lábios e sem qualquer alteração sistêmica. Foi realizado análise da vascularização labial e distribuição do material preenchedor nos tecidos através de imagens de ultrassom. Também foram analisados a adequação do volume, contorno, hidratação dos lábios e satisfação da paciente. Para se atingir o perfil labial desejado utilizou-se 3 ml do material preenchedor ao longo de 4 sessões. Terapia com toxina botulínica foi associada para o controle das forças musculares depressoras do ângulo da boca, orbicular bucal e ponta do nariz. Uma pequena quantidade de material preenchedor foi usada na ponta do nariz para a harmonia do perfil facial. Lábios finos exigem maiores volumes de material preenchedor considerados seguros e efetivos desde que se monitore a vascularização para a decisão do melhor plano de inserção do material preenchedor. A conjugação com terapias complementares como uso da toxina botulínicas pode ser indicada para a efetividade do contorno e forma deste padrão labial. 1 meses caucasiana idade sistêmica ultrassom paciente utilizouse utilizou sessões boca facial

ABSTRACT The goal of this study is to describe the effect of hyaluronic acid filler on thin lips, evaluating the distribution of the material and its relationship with tissue vascularization, as well as the effectiveness of structuring tissue shape and volume through the immediate clinical results achieved. In addition, this study observes the longevity of the results for a period of 10 months after performing this intervention on the lips. Methodology: A healthy 40-year-old Caucasian woman, complaining of thin lips and who had never undergone clinical or surgical procedures on her lips, participated in this study. An analysis of the lip vascularization and distribution of the filler material in the tissues was carried out using ultrasound images. The adequacy of volume, contour, lip hydration and patient satisfaction were also analyzed. Results: To achieve the desired lip profile, 3 ml of filler material was used throughout 4 sessions. Botulinum toxin therapy was applied to control the depressant muscle forces of the angle of the mouth, the orbicularis oris muscle, and the tip of the nose. A small amount of filler material was used at the tip of the nose to harmonize the facial profile. Conclusions: Thin lips required larger volumes of filler material, which was considered safe and effective if the vascularization is monitored to decide on the best insertion plan for the filler material. A combination with complementary therapies, such as the use of botulinum toxin, may be recommended for the effectiveness of the contour and shape of this lip pattern. achieved addition 1 Methodology 40yearold yearold 40 year old woman images analyzed Results profile sessions mouth Conclusions therapies pattern

RESUMO Objetivo: Avaliar a eficiência de três instrumentos diferentes nos canais radiculares de molares decíduos artificiais, bem como a qualidade das obturações. Métodos: Sessenta molares decíduos artificiais foram divididos em três grupos de 20 dentes. Cada grupo foi submetido a uma técnica diferente: Grupo 1 - técnica manual convencional com limas Kerr; Grupo 2 - técnica manual com limas de níquel-titânio; Grupo 3 - Técnica rotatória de níquel-titânio. Os canais radiculares foram preenchidos com pasta de hidróxido de cálcio. Aspectos como homogeneidade das obturações, conicidade e fluidez das preparações foram considerados comparativamente para avaliar a qualidade das instrumentações. Os testes não paramétricos de Kruskal-Wallis e Mann-Whitney foram utilizados para comparar a eficiência do preparo do canal radicular considerando os tempos de preparo dos mesmos. Resultados: Todas as três técnicas foram igualmente eficazes na modelagem dos canais radiculares. O tempo de trabalho foi menor com o instrumento rotatório (p=0,000). Nas comparações pareadas, o tempo de trabalho foi menor com o instrumento rotatório em comparação com as técnicas manuais com limas de aço (p=0,000) e limas de NiTi (p=0,000). Comparando as técnicas manuais, o tempo de trabalho foi menor com as limas de NiTi em comparação com as limas de aço (p=0,011). Além disso, foi encontrada menor variabilidade no tempo de preparo quando o instrumento rotatório foi utilizado. Conclusão: O método rotatório levou um menor tempo operatório em comparação com as técnicas manuais e, portanto, é uma opção preferível para o preparo dos canais radiculares de dentes decíduos.

ABSTRACT Objective: The purpose of the present in vitro study was to evaluate the efficiency of three different instruments in the root canals of artificial primary molars as well as the quality of the fillings. Methods: Sixty artificial primary molars were divided into three groups of 20 teeth. Each group was submitted to a different technique: Group 1 - conventional manual technique using Kerr files; Group 2 - manual technique with nickel-titanium files; Group 3 - NiTi rotary technique. The root canals were filled with calcium hydroxide paste. Aspects such as homogeneity of the fillings, taper and flowability of the preparations were considered comparatively to assess the quality of the instrumentations. The non-parametric Kruskal-Wallis and Mann-Whitney tests were used to compare the efficiency of the preparation of the root canal considering the preparation times of them. Results: All three techniques were equally effective at shaping the root canals of primary teeth. The working time was shorter with the rotary instrument (p=0.000). In the pairwise comparisons, working time was shorter with the rotary instrument compared to the manual techniques with steel files (p=0.000) and NiTi files (p=0.000). Comparing the manual techniques, the working time was shorter with NiTi files compared to steel files (p=0.011). Moreover, less variability in the preparation time was found when the rotary instrument was used. Conclusions: The mechanized rotary method led to a shorter operating time in comparison to the manual techniques and is therefore a preferable option for the preparation of the root canals of primary teeth.

Abstract Objective: To perform an in vivo evaluation on the agreement between measurements of working length obtained by conventional radiographic examinations and an apex locator in deciduous teeth with or without root resorption. Material and Methods: Nine canals of teeth from children ranging from 3 to 5 years old were selected. Endodontic access was performed with a spherical diamond tip, the pulp was removed with Kerr-type steel files, and the canal was irrigated with 1% sodium hypochlorite. A file, compatible with the channel gauge, was then used to measure the length of the root canal with the apex locator. Conventional radiographs were also performed and, using a millimeter endodontic ruler, the length of the canal was determined. The differences between the measurements obtained between the two methods were analyzed using the Student's t-test. Results: The mean canal length for conventional radiography was 9.83 mm and 9.67 mm for the apex locator. The results of this study did not show significant differences (p=0.641), independent of the presence or absence of physiological root resorption. Conclusion: The similarity in measurements obtained with X-ray or an apex locator indicates that it is not necessary to use X-rays as a complement to obtain the working length. The use of the apex locator can provide a quicker treatment, reducing the clinical time and stress of the child.

Abstract Objective: To evaluate the Antimicrobial Photodynamic Therapy (aPDT) in infected deciduous teeth by quantifying the viable bacteria in root canal treatment. Material and Methods: Radicular canal cultures were collected (n= 10). Four intra-canal samples were collected at four different times in each of the sampled teeth, as follows: Time 1 (T1), baseline: After opening the pulp-chamber; Time 2 (T2): After application of aPDT; Time 3 (T3): After mechanical, chemical manipulation; Time 4 (T4): After a second application of aPDT. The aPDT was performed with a 4J/cm energy low-intensity diode, together with 0.005% methylene blue as a photosensitizer. The clinical specimens were taken to the laboratory for a bacteria count (colony forming units) and the results were statistically analyzed using the Friedman and Wilcoxon tests, with a significance level of α=0.05. Results: Statistical differences were seen between the numbers of bacteria at times T1-T2, T1-T3 and T1-T4 on the cultivated plates. However, no significant statistical differences were observed between the number of bacteria in samples T2-T3, T2-T4 and T3-T4. Conclusion: Antimicrobial photodynamic therapy can be a good co-adjuvant in root canal decontamination of necrotic primary teeth.

Abstract Objective: To discover the perceptions of pediatric patients, their parents and undergraduate Dentistry students of the use of the diode laser in frenectomy surgeries. Material and Methods: A qualitative study was conducted through semi-structured interviews, recorded and transcribed with subsequent content analysis. Twelve healthy children (5-8 years old) who needed a frenectomy were selected and invited, together with their parents, to undergo laser diode surgery. In addition, 28 undergraduate dentistry students were invited to attend the procedures. One week after performing the surgical procedures, the children (Group 1), their parents (Group 2) and the students who attended the procedures (Group 3) were individually interviewed for the thematic analysis. Results: The analysis of the conversations identified three emerging contents: positive thoughts on the use of diode laser; frustrations from the use of diode laser; and aspects related to professional training. Conclusion: The results pointed to the acceptance of surgical laser use in pediatric dentistry; however, the feelings of frustration indicate that its use requires guidance from the child and his/her parents, in addition to careful handling and specific training.

RESUMO A fusão dentária é classificada como uma alteração de desenvolvimento referente à união de dois germes dentários, podendo incluir coroa, raiz e polpa. Este tipo de alteração ocorre durante o desenvolvimento intraósseo, resultando em um dente morfologicamente irregular, podendo acometer tanto a dentição decídua quanto a permanente. Frequentemente são associados problemas clínicos como alterações estéticas, falta de espaço e maior susceptibilidade a lesões cariosas. É importante ressaltar que a fusão é comumente confundida com a geminação dentária, que apresenta o mesmo aspecto clínico em boca, porém é resultante de um único germe dentário. O objetivo deste estudo é apresentar um caso clínico de fusão de dois incisivos inferiores decíduos, as perspectivas de tratamento da anomalia e discutir sua repercussão durante o desenvolvimento da dentição. Realizou-se a exodontia do elemento citado e o planejamento do tratamento ortodôntico recomendado foi discutido visando a melhora dos aspectos funcional e estético. Um planejamento integrado entre a Odontopediatria e Ortodontia proporcionou uma melhor alternativa de tratamento.

ABSTRACT Fused teeth are a developmental anomaly involving the union of two dental germs at the crown, root or pulp. This type of anomaly occurs during intraosseous development, resulting in a morphologically irregular tooth that can affect both the primary and permanent dentition. Clinical problems involving esthetics, a lack of space and greater susceptibility to caries are often associated with fused teeth. This type of anomaly is easily confused with dental twinning, which has similar clinical features but emerges from a single dental germ. The aim of the present study was to report a clinical case of the fusion of two deciduous mandibular incisors, describe prospects for treating this anomaly and discuss its repercussions during the development of the dentition. Extraction of the fused tooth was performed and orthodontic treatment was recommended for esthetic and functional improvements. Integrated planning involving both Pediatric Dentistry and Orthodontics provided a better treatment option.

ABSTRACT BACKGROUND: Children with sickle cell disease may have their quality of life affected by oral alterations. However, there is still little data on oral health-related quality of life in these children. The aim of this study was to investigate the influence of sickle cell disease, socioeconomic characteristics, and oral conditions on oral health-related quality of life of children and teens. METHOD: One hundred and six children and teens with sickle cell disease were compared to a similar sample of 385 healthy peers. Data were collected through oral examinations, interviews to assess quality of life (Child Perceptions Questionnaire for children aged 8-10 and 11-14) and questionnaires containing questions on socioeconomic status. RESULTS: There were no statistically significant differences in the total scores of the Child Perceptions Questionnaires or domain scores comparing sickle cell disease patients to control subjects. When sub-scales were compared, oral symptoms and functional limitations had a greater negative impact on the quality of life of adolescents with sickle cell disease (p-value <0.001 and p-value <0.01, respectively) when compared to healthy controls. The only statistically significant determinants of negative impact on oral health-related quality of life in the overall sample was home overcrowding (more than two people/room) in the younger children's group, and dental malocclusion among teens. CONCLUSION: There was no significant difference in the negative impact on the oral health-related quality of life between the group with sickle cell disease and the control group. Of the oral alterations, there was a significant difference in the oral health-related quality of life between adolescents with sickle cell disease and controls only in relation to malocclusion. Among the socioeconomic characteristics, only overcrowding was significantly associated with a negative impact on oral health-related quality of life.

Abstract The aim of this study was to assess the impact of oral conditions of children with sickle cell disease (SCD) on their parents’ quality of life (QoL). A cross-sectional study was performed with parents of outpatients suffering from SCD at a hematology referral center in Belo Horizonte, MG. A qualified dentist performed an intraoral exam. The Family Impact Scale (FIS) was used to assess the parents’ perception of QoL. The parents answered some questions regarding sociodemographic and medical information about their children. The dmft/DMFT score, DAI, gum bleeding and SCD severity were evaluated in terms of their impacts on the overall mean FIS scores and subscale scores. The chance of more frequent impacts was greater in parents of adolescents (OR = 2.04; 95%CI = 1.2, 3.4) than of younger children. Dental caries (dmft/DMFT ≥ 1) had a negative impact on the QoL of parents of younger children and adolescents (p < 0.05 and p < 0.01, respectively). Among the parents of younger children, dental caries and SCD severity significantly affected the subscales for parental activities (PA) and parental emotions (PE) (p < 0.01, p < 0.05, respectively). Among parents of adolescents, dental caries (DMFT) and severe malocclusion adversely affected the PE and PA subscales (p < 0.01, p < 0.05, respectively). SCD severity affected the overall FIS score among young children’s parents (p < 0.05). In conclusion, dental caries, age and SCD severity were associated with a negative impact on the QoL of parents of children with SCD
