Abstract The aim of this study was to investigate the prevalence of unsatisfactory dental restorations on posterior primary teeth and associated factors in school children aged six to ten years. A cross-sectional study was conducted with children randomly selected from public schools in a small Brazilian town. Questionnaires were sent to the guardians addressing socioeconomic and behavioral aspects of the child. Oral examinations were performed at the schools to determine the quality of dental restorations, visible biofilm, and presence of moderate/extensive untreated caries (scores 3-6 ICDAS). This examination was performed by two previously trained and calibrated examiners. Associations were tested using multilevel logistic regression. Among the 400 children evaluated, 98 had restorations (217 teeth). The prevalence of unsatisfactory restorations was 34.6%. Restorations in amalgam were less likely to fail compared to those in glass ionomer cement (OR = 0.11; 95%CI: 0.02–0.49; p = 0.005). Children with moderate/extensive untreated caries were more likely to have unsatisfactory restorations (OR = 6.79; 95%CI: 2.20–20.93; p = 0.001). Children with a visible plaque index ≥ 20% were also more likely to have unsatisfactory restorations (OR = 2.28 95%CI: 1.05–4.92; p = 0.036). The prevalence of unsatisfactory restorations was high. The occurrence of this outcome was associated with restorative material, presence of caries, and visible plaque.

Resumen El adenoma pleomórfico, también conocido como tumor mixto benigno, es la neoplasia mas común tanto en glándulas salivales mayores como en menores. Suele presentarse como una lesión firme de crecimiento lento y asintomático. En glándulas salivales menores, el sitio preferencial está en el paladar, seguido del labio superior y mucosa yugal. Su diagnostico esta basado en el aspecto histopatológico en que puede ser bastante diversificado. El tratamiento del adenoma consiste en la remoción quirúrgica. El objetivo de este trabajo fue describir un caso de adenoma pleomórfico de aproximadamente cuatro centímetros localizado en el labio superior de una paciente del sexo femenino, 68 años, que ha sido tratada por escisión quirúrgica

Abstract Pleomorphic adenoma is the most common salivary gland neoplasm in both the major and minor salivary glands. It presents like a solid tumor of slow growth and asymptomatic. On minor salivary glands, the site more often affected is the hard palate, followed by the upper lip and buccal mucosa. The diagnosis is base on the histopathology features that can be very diversificated. Pleomorphic adenoma’s treatment consists at surgical excision The aim of this study was to report a case of pleomorphic adenoma, of 4cm in dimension in upper lip of a female patient, 68 years old that was treated by surgical treatment

Resumo Adenoma Pleomórfico é o tumor de glândula salivar mais comum tanto em glândulas maiores como nas menores, apresentando crescimento lento e assintomático. O local preferencial de acometimento, em glândulas salivares menores, é palato duro, seguido pelo lábio superior e mucosa jugal. Seu diagnóstico é baseado nos aspectos histopatológicos que podem se apresentar de forma bastante diversificada. Seu tratamento consiste em excisão cirúrgica. O objetivo deste trabalho foi relatar um caso de adenoma pleomórfico de 4 cm localizado em lábio superior de uma paciente do sexo feminino, 68 anos de idade, que foi tratado cirurgicamente

O objetivo deste estudo foi associar freqüência de higiene bucal e presença de biofilme visível na dentição decídua. A amostra constou de 90 crianças com idade até 4 anos, cadastradas no Hospital Universitário da Universidade do Estado do Rio de Janeiro. Os exames foram realizados em consultório odontológico por um único examinador treinado, auxiliado por um anotador. Os pais responderam a um questionário estruturado sobre métodos e freqüência de higiene bucal. Foram utilizados dois índices de biofilme: um simplificado (BF1) e um convencional (BF2). O BF1 classifica o biofilme como ausente, fino ou espesso, em dentes anteriores e/ou posteriores, gerando um escore para o paciente, enquanto o BF2 classifica o biofilme como ausente ou presente, fornece escores a três superfícies de cada dente e o escore final corresponde ao percentual de superfícies com biofilme. Mais da metade dos pais (51 - 56,7%) relataram limpar os dentes dos filhos pelo menos duas vezes ao dia ao passo que 7 (7,8%) nunca tinham limpado os dentes dos filhos. O BF1 demonstrou que 12,2% (11) das crianças não apresentavam biofilme visível, 37,8% (34) apresentavam biofilme fino em dentes anteriores e/ou posteriores, 27,8% (25), biofilme espesso em dentes anteriores ou posteriores, e 22,2% (20), biofilme espesso em dentes anteriores e posteriores. O BF2 revelou uma média de 21,8% (d.p. 16,5). Não foram encontradas correlações estatisticamente significativas entre a freqüência de higiene bucal e os índices de biofilme (p > 0,05), demonstrando que a freqüência de higiene bucal não esteve associada à qualidade da mesma na amostra estudada.

The purpose of this study was to associate oral hygiene frequency and presence of visible biofilm in the primary dentition. The sample consisted of 90 children, aged up to 4 years old, outpatients of the University Hospital of the Rio de Janeiro State University. The examinations were carried out in a dental office by a single trained examiner who was aided by an assistant. The parents answered a structured questionnaire about oral hygiene methods and frequency. Two biofilm indices, one simplified (BF1) and the other conventional (BF2), were used. BF1 classifies biofilm as absent, thin or thick, in anterior and/or posterior teeth, and provides a score for the patient, whereas BF2 classifies biofilm as absent or present, provides scores for three surfaces of each tooth and the final score is the percentage of tooth surfaces with biofilm. More than half of the parents (51 - 56.7%) reported they cleaned their child's teeth at least twice a day, while 7 (7.8%) had never cleaned their child's teeth. BF1 revealed that 12.2% (11) of the children had no visible biofilm, 37.8% (34) had thin biofilm in anterior and/or posterior teeth, 27.8% (25) had thick biofilm in anterior or posterior teeth and 22.2% (20) had thick biofilm in both anterior and posterior teeth. BF2 revealed a mean value of 21.8% (s.d. 16.5). No statistically significant correlations were found between oral hygiene frequency and the two biofilm indices (p > 0.05), indicating that oral hygiene frequency was not associated to oral hygiene quality in the evaluated sample.
