RESUMO

A dieta não cariogênica e a higiene oral tão logo irrompa o primeiro dente podem favorecer a manutenção de saúde bucal. Sabendo-se que no primeiro ano de vida do bebê o contato se dá com maior frequência com o médico pediatra, foi avaliado o conhecimento sobre saúde bucal de pediatras, dos setores: público e privado, de Belo Horizonte. De total de 614 pediatras inscritos no CFM na capital mineira, 322 foram visitados, destes 147 aceitaram responder um questionário. Observou-se que 95,3% examina a cavidade bucal, apenas 24,5% recomenda a mamadeira, e em relação a chupeta, os entrevistados ficaram divididos: 44,9% contra indicam e 53,1% não contra indicam seu uso. Para substituir o leite materno ou complementar após 6 meses de vida, a fórmula infantil foi indicada por 93%.0 encaminhamento para o dentista só é feito com frequência por um terço dos pediatras entrevistados. A higiene bucal ao irromper o primeiro dente foi recomendada por 8,8% e o uso de creme dental por 59,2%. Concluiu-se que o conhecimento a respeito da saúde bucal dos médicos pediatras entrevistados não está de acordo com as diretrizes preconizadas pela ABO-Odontopediatria, pela SBP, sendo assim os pediatras precisam encaminhar os pacientes no primeiro ano de vida para consulta odontopediatrica para receberem as orientações preventivas necessárias

Non-cariogenic diet and oral hygiene as soon as the first tooth erupts may favor the maintenance of good oral health. Because in the first year of the babv's life, the contact with the pediatrician occurs more frequently, the knowledge of 147 public and private sector pediatricians in Belo Horizonte was evaluated. Total of 614 pediatricians enrolled in CFM in Belo Horizonte, 322 were visited, these, 147 agreed to answer one questionnaire. It was observed that the 95,3% of them examines the oral cavity, 24.5% recommends the baby bottle. Regarding suggesting the use or not of pacifier the interviewees were divided. Suggestion for replacement of the maternal milk or need of complementary milk during the first 6 months the child formula was indicated by 93% of the interviewees. The referral to the dentist is often made by one third of the interviewees. The oral hygiene upon being erupts the first tooth was recommended by 8.8% and the use of toothpaste for 59.2%, but the use of fluoride was indicated by 17% of phvsicians. We can conclude that the knowledge of interviewed pediatricians about the oral health is not in accordance with the guidelines recommended by the ABO-Dentistry, SBP, AAP and AAPD

RESUMO

AIM: This in vitro study aimed to test the performance of fluorescence-based methods in detecting occlusal caries lesions in primary molars compared to conventional methods. DESIGN: Two examiners assessed 113 sites on 77 occlusal surfaces of primary molars using three fluorescence devices: DIAGNOdent (LF), DIAGNOdent pen (LFpen), and fluorescence camera (VistaProof-FC). Visual inspection (ICDAS) and radiographic methods were also evaluated. One examiner repeated the evaluations after one month. As reference standard method, the lesion depth was determined after sectioning and evaluation in stereomicroscope. The area under the ROC curve (Az), sensitivity, specificity, and accuracy of the methods were calculated at enamel (D1) and dentine caries (D3) lesions thresholds. The intra and interexaminer reproducibility were calculated using the intraclass correlation coefficient (ICC) and kappa statistics. RESULTS: At D1, visual inspection presented higher sensitivities (0.97-0.99) but lower specificities (0.18-0.25). At D3, all the methods demonstrated similar performance (Az values around 0.90). Visual and radiographic methods showed a slightly higher specificity (values higher than 0.96) than the fluorescence based ones (values around 0.88). In general, all methods presented high reproducibility (ICC higher than 0.79). CONCLUSIONS: Although fluorescence-based and conventional methods present similar performance in detecting occlusal caries lesions in primary teeth, visual inspection alone seems to be sufficient to be used in clinical practice.

RESUMO

The aim of this study was to evaluate the influence of dental plaque and moisture on performance of a laser fluorescence device in detecting occlusal and proximal caries lesions in primary teeth. Fifty-five occlusal and 58 proximal sites on primary molars were evaluated using a DIAGNOdent pen (LFpen) device. For the drying time study, the evaluations were performed in: (I) moist teeth; (II) teeth dried for 3 s, or (III) dried for 15 s. For the plaque study, the evaluations were done in sites: (I) without plaque; (II) with plaque, and (III) after cleaning. Evaluation of the teeth sections in stereomicroscope was the reference standard method. LF pen values, sensitivity, specificity, and accuracy were compared. The values obtained after 15 s of drying were higher than those obtained with moist teeth or dried for 3 s at both occlusal and proximal surfaces. However, there was no change in the performance in detecting caries lesions. With regard to the presence of plaque, there was no significant change in the readings of the device, but specificity was decreased in occlusal surfaces with plaque. At proximal surfaces, however, no significant differences were observed. In conclusion, the moisture conditions do not influence significantly the performance of the LFpen, but the presence of plaque can affect its performance in detecting occlusal caries lesions in primary teeth.
