ABSTRACT
To assess the dental caries prevalence with ICDAS II in the mixed dentition, 40 children aged 7 to 11 years old, participating in a social program, whose parents and/or guardians signed a informed consent form.Material and Methods:Clinical examination was carried out after brushing. A single researcher performed the examination and the diagnosis consistency was obtained by Kappa coefficient in 12% of the sample. All dental surfaces were examined receiving a two-digit code. The first one refers to the presence of restoration/sealant and the second, the severity of carious lesions. The data was processed at SPSS software version 10.0 and analyzed using descriptive statistics (absolute distribution, percentage, mean and standard deviation). Results:The coefficient intra-examiner agreement was 0,83.Caries prevalence was considered high because 100% of the children had some surface with non-cavitated caries lesion. ICDAS II can be easily transformed to dmf-s or DMF-S without compromising its integrity. For dmf-s/DMF-S decayed surfaces were consideredICDAS codes 3 to 6, resulting in a dmf-s = 6,57 where 11 children (27,5%) presented no decayed deciduous teeth surface. DMF-S = 2,0 showed that 15 children (37,5%) had none decayed permanent surface, determining a underestimation of the caries disease when using dmf-d/dmf-s and DMF-S indexes.Conclusion:A careful viewing of initial caries lesions makes ICDAS II usefull in evaluating the health promotion actions impact, supporting the planning process, implementation and evaluation of program activities...

Introdução - Clorexidina tem demonstrado efetividade na redução das contagens de Estreptococos Grupo Mutans (SM) na saliva e placa dentária. Entretanto, poucos estudos clínicos avaliaram seus efeitos na dentadura mista. O objetivo deste trabalho foi avaliar o tratamento intensivo com clorexidina (gel a 1%) em comparação com o tratamento com flúor fosfato acidulado a 1, 23%, na redução das contagens salivares de SM em crianças ente 5 a 11 anos. Materiais e Métodos - Os participantes receberam tratamento odontológico na clínica de Odontologia Pediátrica do Hospital Universitário de Brasília - (HUB), Brasília - Brasil. Trinta e cinco crianças saudáveis foram alocadas em dois grupos formados por randomização simples (G1 /G2). O Grupo 1 (G1) recebeu seis aplicações de Clorexidina em dois dias consecutivos. O Grupo 2 (G2) recebeu duas aplicações de flúor durante 4 minutos, também em dois dias consecutivos. As contagens salivares foram realizadas através do Kit CARITEST SM - Herpo Produtos Odontológicos - Rio de Janeiro - Brasil, antes do tratamento (baseline) e após 4, 12 e 24 semanas. A análise estatística foi realizada pelo teste de Tukey (p<0,05). Resultados - Os resultados mostraram que somente no G1 as médias das contagens salivares foram significantemente reduzidas (82,14%). Após 24 semanas, houve aumento nas contagens salivares no G2 (não significativo) e tendência à redução nas contagens do G1, em comparação com a baseline. Conclusão - Os resultados permitem concluir que o tratamento intensivo com Clorexidina foi efetivo na redução das contagens salivares de SM durante 4 e 12 semanas após dupla aplicação, havendo, no entanto, retorno aos níveis iniciais ao final de 24 semanas.
Introduction - Chlorhexidine has been shown effective in reducing mutans streptococci (SM) counts in saliva and dental plaque. To date, few studies have compared its effects in mixed dentition children. The aim of the study was to assess the effects of an intensive treatment of 1% Chlorhexidine gel in comparison to a conventional fluoride preventive treatment on MS counts in saliva of children from 5 to 11 years old. Materials and Methods - All the participants received general dental care in the Pediatric Clinic at the Hospital of the University of Brasília - DF, Brazil . Thirty-five healthy children were randomly assigned in 2 groups. Group 1 (G1) received 6 applications of Chlorhexidine in 2 consecutive days. Group 2 (G2) received 2 applications of 1,23% sodium fluoride gel during 4 minutes. The MS salivary counts were determined by CARITEST SM Kit (Herpo Dental Products - Rio de Janeiro - Brazil) at the baseline, prior to treatments, and after 4, 12 and 24 weeks. The data were statistically analyzed by Tukey test (P<0,05). Results - Results showed that in G1 the MS mean counts were significantly reduced by chlorhexidine treatment at 4 and 12 weeks (82, 14%), while the G2 mean counts were not significantly affected. After 24 weeks there was a slight increase in MS counts in G2 (non significant) and a reduction tendency in G1, compared to the baseline counts. Conclusion - It was concluded that chlorhexidine intensive treatment was effective at reducing SM salivary counts during 4 and 12 weeks after double application, however there was a return to the baseline counts after 24 weeks.

O presente estudo teve por objetivo analisar como as faculdades de Odontologia do Brasil ensinam a técnica de odontometria na dentição decídua para seus alunos de graduação e pós-graduação. Um questionário contendo perguntas a cerca do tratamento endodôntico radical em dentes temporários foi enviado para 51 instituições de ensino superior e a taxa de resposta foi de 45% (23 faculdades). De acordo com os resultados obtidos, pôde-se perceber que, assim como na literatura, não houve consenso quanto à técnica de odontometria preconizada para os dentes decíduos.
