ABSTRACT Objective: To determine the prevalence and risk factors associated with dental caries in Brazilian preschool children aged 2 to 5 years. Material and Methods: The following independent variables were evaluated: dental caries, dental trauma, and malocclusions. Data were analyzed using the Mann-Whitney test and Poisson regression (p<0.05). Results: The prevalence of dental caries in preschoolers was 55.1%. Child age, family income, maternal education, and tooth color alteration from trauma were significantly associated with dental caries (p<0.05). The final adjusted multivariate model showed a significant association between maternal education and dental caries; children of mothers with low education were 1.89 times more likely to have caries (PR: 1.89; 95%CI: 1.40-2.55) (p<0.01). Children with tooth color change from trauma were more likely to have dental caries (PR: 1.69; 95%CI: 1.22-2.34 (p=0.001). Conclusion: Child age, family income, maternal education, tooth discoloration and discoloration color are risk factors for the development of caries disease in children. Also, children of mothers with low educational levels have a higher chance of developing dental caries.

ABSTRACT Objective: To understand the susceptibility to single nucleotide polymorphisms in the promoter region of Interleukin-4 (IL-4) and Interleukin-13 (IL-13) in patients with and without periodontal disease. Thus, a systematic review of available studies on the subject was performed. Material and Methods: A protocol was conducted for registration in the International Prospective Register of Systematic Reviews (PROSPERO) under CRD42021246646. For this search, studies were selected from the Scopus, Web of Science, Virtual Health Library, Embase, Cochrane Library, and PubMed databases. The selection criteria consisted of case-control and cohort studies published in English that had data on IL-4 and IL-13 genetic polymorphisms in patients with and without periodontal disease in the same study. The obtained studies were managed by EndNote Program™ X7 version and the Rayyan Platform. Regarding the risk of bias, we used the Newcastle-Ottawa Scale, which classified the studies using high-quality methodology. Results: After the selection process, three studies presented the eligibility criteria. No relation between IL-13 and susceptibility to periodontal disease was found. IL-4 gene (IL-4 -590C/T; IL-4-34C/T; rs2243248) was associated with susceptibility to the development of periodontitis. Conclusion: An association between IL-4 and the susceptibility of periodontitis was verified. Further case-control studies are needed to create more concrete conclusions on the subject.

ABSTRACT Objective: To evaluate the oral health and related factors among people with visual impairment in a municipality in southeastern Brazil. Methods: A cross-sectional and descriptive household study was carried out on a representative sample of people with visual impairments in a medium-sized city in Brazil. A clinical-dental examination was performed (evaluating tooth loss, caries, periodontal health, dental plaque use and need of prosthesis) and a semistructured questionnaire was applied, investigating the socioeconomic conditions (sex, age, marital status, skin color and income) and the use of dental services (reason, time since, and type of service used [private/public] in last dental visit). Descriptive and bivariate analysis were performed to asses the factors related to oral health. Results: The mean age of participants was 65 years (±15.05), with the majority women (70.9%). 53.1% of the interviewees were edentulous, but 58.2% had a good perception of oral health. The blind ones use less public services (p=0.038) and with a lower frequency (p=0.014) than subjects with low vision. Those with less schooling had higher tooth loss and lower periodontal problems (p <0.05). There was a reduction of dental plaque six months after the educational action (30.7%; p=0.01), especially among the low vision participants (p=0.01). Conclusion: Severe tooth loss and unsatisfactory hygiene contrast with self-perception of oral health. Visual acuity and schooling were related to access and oral health. Actions for promotion and equity are necessary to overcome the inequalities encountered.

RESUMO Objetivo: Avaliar a saúde bucal e fatores relacionados entre deficientes visuais em município do sudeste brasileiro. Métodos: Foi realizado um estudo domiciliar, transversal e descritivo em uma amostra representativa de pessoas com deficiência visual em uma cidade de médio porte do Brasil. Realizou-se o exame clínico bucal (avaliando perda dentária, cárie, saúde periodontal, placa dentária, uso e necessidade de prótese) e aplicou-se um questionário semiestruturado, investigando as condições socioeconômicas (sexo, idade, estado civil, cor da pele e renda) e o uso de serviços odontológicos (motivo, tempo decorrido e tipo de serviço utilizado [privado/público] na última consulta odontológica). Foram realizadas análises descritivas e bivariadas para avaliar os fatores associados à saúde bucal. Resultados: A idade média dos participantes foi de 65 anos (±15,05), com maioria de mulheres (70,9%). 53,1% dos entrevistados eram edêntulos, porém, 58,2% apresentaram percepção de saúde bucal boa. Os cegos usam menos os serviços públicos (p=0,038) e em menor frequência (p=0,014) que os sujeitos com baixa visão. Os menos escolarizados apresentam maiores perdas dentárias e menores problemas periodontais (p<0,05). Houve redução de placa dentária seis meses após ação educativa (30,7%; p=0,01), sobretudo entre os sujeitos com baixa visão (p=0,01). Conclusão: Elevada perda dentária e higienização insatisfatória contrastaram com autopercepção dos agravos bucais. Acuidade visual e escolaridade relacionaram-se ao acesso e saúde bucal. Ações de promoção e equidade são necessários para superar desigualdades encontradas.

Abstract Background Patients with chronic renal failure may have their oral health impaired as a result of the disease itself, its treatment, and its associated lifestyle alterations. Objective To assess the factors associated with poor self-rated oral health among adults with chronic renal failure treated by hemodialysis. Method This is a cross-sectional study with 243 adults undergoing hemodialysis in a hospital in Minas Gerais, Brazil in 2013-2014. The outcome was assessed by the self-report of oral health categorized into good (excellent/good) and bad (fair/bad / very bad). The independent variables included sociodemographic conditions, general health, oral health, and the use of dental services were collected through a structured questionnaire. The association between the outcome and the independent variables was tested using multiple logistic models with hierarchical inclusion of variables. Results The prevalence of poor self-rated oral health was 35.4%. The youngest (p = 0.015), those who have undergone hemodialysis in the shortest time (p = 0.016), have halitosis (p <0.001), need dental treatment (p <0.001), and had their last dental appointment not for pain (p = 0.027) expressed higher odds of poor self-rated oral health, independently of sociodemographic and health conditions.

Resumo Introdução Pacientes com insuficiência renal crônica podem apresentar prejuízos em sua saúde bucal em decorrência da própria doença, do tratamento e das alterações de estilo de vida associadas. Objetivo Avaliar os fatores associados à autoavaliação de saúde bucal ruim entre adultos com insuficiência renal crônica submetidos à hemodiálise. Método Estudo transversal com 243 adultos submetidos à hemodiálise em um hospital do sul de Minas Gerais nos anos de 2013 e 2014. O desfecho foi avaliado pelo autorrelato da condição bucal dicotomizada em boa (ótima/boa) e ruim (regular/ruim/péssima). As variáveis independentes incluíram condições sociodemográficas, saúde geral, saúde bucal e uso de serviços odontológicos, a partir de informações coletadas por meio de questionário. A associação entre o desfecho e as variáveis independentes foi testada por meio de modelos logísticos múltiplos com inclusão hierarquizada de variáveis. Resultados A prevalência de autoavaliação de saúde bucal ruim foi de 35,4%. Os mais jovens (p = 0,015), os que se submetem à hemodiálise há menos tempo (p = 0,016), têm halitose (p <0,001), necessitam de tratamento odontológico (p <0,001) e tiveram a última consulta odontológica por motivo diferente de dor (p = 0,027) expressaram maiores chances de autoavaliação de saúde bucal ruim, independentemente de condições sociodemográficas e de saúde.

RESUMO Objetivo: Este estudo verificou a autopercepção, as características bucais e os aspectos odontológicos dos participantes da Universidade Aberta a Terceira Idade (UNATI). Métodos: Refere-se a um estudo epidemiológico transversal com indivíduos a partir de 50 anos de idade que frequentam o programa UNATI-UNIFAL/MG. O instrumento de coleta de dados consistiu em um questionário semiestruturado, composto por perguntas referentes à saúde bucal, interferência da mesma na autoestima e alimentação, entre outros. Além disso, foi utilizada uma ficha clínica baseada nas propostas do Levantamento em Saúde Bucal 2010. Foram realizadas análises descritivas, uni e multivariadas. Resultados: A amostra foi composta por 106 indivíduos, com idade média de 62,4 anos, dentre os quais 59,4% visitaram o cirurgião-dentista no último ano para exames de rotina e/ou estética (38,7%). As condições clínicas evidenciaram que apenas 19,8% dos indivíduos eram desdentados totais, o CPOD médio de 26,1 e 37,7% usava algum tipo de prótese total superior, inferior ou ambas. Quanto a autopercepção das condições bucais, 34,9% se refere regular, contudo, na estatística aplicada a presença de dor determinou uma pior percepção e não esteve correlacionada com a perda de dentes, presença de próteses e/ou dentes restaurados. Conclusão: A autopercepção das condições bucais é regular e as características clínico-odontológicas avaliadas revelaram indivíduos desdentados parciais com elevado CPOD. Ao avaliar os aspectos odontológicos a maioria não apresentou dificuldades ao procurar o cirurgião-dentista, visitaram esse profissional no último ano e o tratamento mais procurado por eles foi o preventivo.

ABSTRACT Objective: This study verified both the self-perception and oral characteristics of a group of elderly participants of the Open University for the Elderly (UNATI). Methods: The sample consisted of a cross-sectional epidemiological study with elderly subjects (50 years of age or older), who attended the UNATI-UNIFAL/MG program. Data collection was carried out using a semi-structured questionnaire consisting of open- and closed-ended questions regarding oral health, its interference with self-esteem and nutrition, among other features. In addition, an application form based on the proposals by the Oral Health Survey 2010, was used. Univariate and multivariate descriptive analyses were performed. Results: The study sample consisted of 106 subjects (mean age of 62.4 years), of whom 59.4% had attended a dental appointment in the last year for routine and/or aesthetic examinations (38.7%). The clinical conditions showed that only 19.8% of the subjects were completely edentulous, an average DMFT of 26.1, and 37.7% used some kind of complete upper dentures, complete lower dentures, or both. Regarding self-perception of oral conditions, 34.9% considered it a regular perception, however in the applied statistics the presence of pain demonstrated a worse perception which was not correlated with teeth loss, presence of dentures and/or restored teeth. Conclusion: The self-perception of oral conditions is regular and the clinical and odontological characteristics evaluated revealed partial edentulous subjects with high DMFT. By evaluating the odontological aspects, it was observed that the majority of the subjects did not have difficulties to look for a dentist, they attended dental appointments in the last year and the preventive treatment had been the most required.

Abstract Low intensity laser can be used as a promising alternative in the treatment of periodontal disease. Objective The aim of this study was to evaluate low-level laser therapy (LLLT) as an adjuvant treatment for scaling and root planing (SRP) for the treatment of induced periodontitis in simvastatin-modified rats. Material and Methods A total of 180 rats were evenly divided into two groups: Veh – receiving oral administration of polyethylene glycol (vehicle); S – receiving oral administration of Simvastatin. Periodontal disease was induced in both groups at the first mandibular molar. After seven days, the ligature was removed and the animals were divided into subgroups according to the following local treatments: NT – no treatment; SRP – scaling and root planing and irrigation with saline solution; and LLLT ¬– SRP and laser irradiation (660 nm; 0.03 W; 4 J). Ten animals in each subgroup/local treatment were euthanized at 7, 15 and 30 days. Samples of gingival tissue were processed to analyze the tissue oxidative damage and radiographic analysis. Levels of oxidative stress were analyzed by the expressions of Tripeptideglutathione (TG), Malondialdehyde (MDA) and Carbonylated Proteins (CP). Results The animals in S group had higher levels of TG and lower levels of MDA and CP compared with Veh group (p<0.05). Radiographically, in the intragroup analysis Veh and S, LLLT showed lower bone loss (BL) compared with NT and SRP, in all experimental periods (p<0.01). In addition, a lower BL was observed for the animals of Veh group treated with LLLT compared with treatment SRP in the S group, in all experimental periods. Conclusion Within the limits of this study, we can conclude that LLLT was effective as adjuvant treatment for SRP protecting against the occurrence of oxidative tissue damages as well as for reducing alveolar bone loss in experimentally induced periodontitis simvastatin-modified rats.

Abstract Objective The objective of this study was to evaluate the local effects of statins as adjuvants for treatment by scaling and root planing (SRP) of periodontal disease induced in rats. Material and Methods Ninety rats were used in the present experiment. Periodontal disease was induced in all animals using a cotton thread placed in the left first mandibular molar. After 7 days of induction, the bandage was removed and the animals were divided into three groups: 1) NT group (n=30), no treatment; 2) SRP group (n=30): SRP and irrigation with control gel; 3) S group (n=30) - SRP and irrigation with Simvastatin. Ten animals from each group were euthanized at 7, 15 and 30 days after treatment. Gingival biopsy specimens were processed to analyze the expression of matrix metalloproteinase 8 (MMP-8). The mandibles were removed and submitted to radiographic and laboratory processing for histometric analysis. Results The S group showed a significantly lower expression of MMP-8 compared to NT and SRP groups in all experimental periods. In the radiographic and histometric analyses between the groups, S group showed a significantly lower bone loss (BL) compared to NT and SRP groups in all experimental periods. Conclusions Within the limits of this study, it can be concluded that locally applied statin was effective as an adjuvant treatment for SRP in rats with induced periodontal disease.

A percepção da condição bucal é um importante indicador de saúde, pois sintetiza a condição real de saúde, as respostas subjetivas, os valores e as expectativas culturais. O estudo avaliou a importância da saúde bucal segundo a percepção de pacientes internados em um hospital da cidade de Araçatuba (SP). Foi aplicado um questionário semi-estruturado para a coleta de dados e utilizado para análise estatística o programa Epi Info 2000. Os resultados mostraram que metade dos pacientes haviam realizado a última visita ao cirurgião-dentista em um período compreendido entre seis a doze meses devido a problemas periodontais (35%) e cárie dentária (20%). Observou-se que, embora todos os pacientes considerassem ter uma "boa" higiene bucal, o tratamento periodontal foi identificado como o de maior necessidade entre os pacientes (67,93%). A presença do cirurgião-dentista no corpo clínico hospitalar foi considerada por todos os entrevistados como fundamental para contribuir no cuidado integral à saúde dos pacientes hospitalizados. Quanto ao papel do dentista em um hospital, a grande maioria dos pacientes (90,63%) afirmou ser o "cuidar dos dentes". Assim, conclui-se que todos os pacientes têm conhecimento do quão é importante a manutenção das condições adequadas de saúde bucal, principalmente em pacientes hospitalizados.

The perception of oral condition is an important health indicator as it synthesizes the condition of objective health, subjective answers, cultural values and expectative. The study evaluated the importance of oral health according to the perception of inpatients of a hospital unit at Araçatuba city, São Paulo State. A partially structured questionnaire was used to collect data. The program Epi Info 2000 was used to statistics analysis. The results show that half of patients affirmed that visited a dental surgeon on a period between 6 and 12 months due to periodontal problems (35%) and dental caries (20%). It was observed that although all patients consider to have a good oral hygiene, the periodontal treatment was identified like the more necessary among them (67.93%). The presence of a dental surgeon at the hospital clinical group was considered by all the patients essential to collaborate with the integral care of health of inpatients. About the role of dental surgeon in a hospital, the majority of patients (90.63%) affirmed to be the act of "caring on the teeth". So, it is possible to conclude that all the patients know the importance of the maintenance of oral health appropriated conditions specially of inpatients.

OBJECTIVE: The aim of this study was to compare subgingival irrigation with tetracycline hydrochloride (TTC-HCL) as adjunctive treatment to scaling and root planning (SRP) on induced periodontitis in rats. MATERIAL AND METHODS: In 60 rats, periodontal disease was ligature-induced at the mandibular left first molar. After 7 days, the ligature was removed and all animals were submitted to SRP, and divided into 2 groups according to the following treatment: C (n=30) - subgingival irrigation with 1 mL of saline; T (n=30) - subgingival irrigation with 1 mL of TTC-HCL (50 mg/mL). Ten animals in each group were euthanized at 7, 15 and 30 days posttreatment. The histometric values were statistically analyzed (p<0.05). RESULTS: In the histometric analysis, at 7, 15 and 30 days, Group T (0.72±0.05 mm², 0.57±0.14 mm², 0.62±0.07 mm²), showed less bone loss (p<0.05) than Group C (1.35±0.25 mm²; 1.40±0.31 mm²; 1.29±0.27 mm²), respectively. CONCLUSIONS: Subgingival irrigation with TTC-HCL was an effective adjunctive treatment for periodontal disease induced in rats.

OBJECTIVE: The aim of this study was to assess radiographically the effect of photodynamic therapy (PDT) as an adjunctive treatment to scaling and root planing (SRP) on induced periodontitis in dexamethasone-induced immunosuppressed rats. MATERIAL AND METHODS: The animals were divided into 2 groups: ND group (n=60): saline treatment; D group (n=60): dexamethasone treatment. In both ND and D groups, periodontal disease was induced by the placement of a ligature in the left first mandibular molar. After 7 days, ligature was removed and all animals received SRP, being divided according to the following treatments: SRP: saline and PDT: phenothiazinium dye (TBO) plus laser irradiation. Ten animals per treatment were killed at 7, 15 and 30 days. The distance between the cementoenamel junction and the height of the alveolar bone crest in the mesial surface of the mandibular left first molars was determined in millimeters in each radiograph. he radiographic values were analyzed statistically by ANOVA and Tukey's test at a p value <0.05. RESULTS: Intragroup radiographic assessment (ND and D groups) showed that there was statistically signifcant less bone loss in the animals treated with PDT in all experimental periods compared to those submitted to SRP. Intergroup radiographic analysis (ND and D groups) demonstrated that there was greater bone loss in the ND group treated with SRP compared to the D group treated with PDT at 7 and 30 days. CONCLUSION: PDT was an effective adjunctive treatment to SRP on induced periodontitis in dexamethasone-induced immunosuppressed rats.
