This in vivo study aimed to evaluate the performance of 2 fluorescence-based methods in detecting occlusal caries lesions in primary teeth, compared with the performance of visual inspection and radiographic methods, and to propose a mathematic correction of the diagnostic parameters due to the imperfect reference standard method used in the study. Two examiners assessed the occlusal surfaces of 407 primary teeth (62 children) using visual inspection (ICDAS), radiographic, DIAGNOdent pen (pen type laser fluorescence; LFpen), and fluorescence camera (FC) methods. At the noncavitated threshold (NC) the reference standard method was the results of ICDAS, and at the dentine caries threshold (D3) teeth diagnosed with dentine caries by ICDAS or radiographic methods were subjected to operative treatment to confirm the presence of lesion. Reproducibility, sensitivity, specificity, accuracy, and the area under the ROC curve were calculated for the methods at both thresholds. At the NC threshold, LFpen had a slightly better performance compared to the FC and radiographic methods. However, at the D3 threshold, both fluorescence-based methods performed similarly. Visual inspection and radiographic methods presented higher specificities but lower sensitivities than fluorescence methods. After corrections, there was a significant decrease in some parameters. In conclusion, both fluorescence-based methods presented similar performance in detecting occlusal dentine caries lesions in primary teeth, but they usually gave more false-positive results than did the visual and radiographic methods. The correction proposed shows that the performance of the methods can be overestimated, and the correction should be validated and considered in further studies that use an imprecise reference standard method.

The FT-Raman technique may be suitable for detecting compositional and structural changes occurring in mineral phases and organic phases of lased enamel under cariogenic challenge.

The purpose of this investigation was to examine the effectiveness of laser fluorescence for monitoring in vitro remineralization of caries lesions. Seventeen natural enamel lesions in primary molars were each cut into two parts. One part was exposed, at room temperature, to a remineralizing solution (experimental) and the other part to water (control) for 28 days. Laser fluorescence readings were taken at the beginning of the experiment and during the experiment. At the end of the experiment, lesion depth in the experimental halves was significantly less than in the control halves (p < 0.01), suggesting that remineralization had occurred. However, the laser fluorescence readings showed no statistically significant changes during the experiment, either in the experimental or control halves. We conclude that laser fluorescence was not able to detect in vitro remineralization of natural incipient caries lesions of primary teeth.

Gingivitis occurs more frequently in children with CP showing increased values of salivary osmolality.

The ProTaper(™) and WaveOne™ systems were equally effective in reducing Enterococcus faecalis in primary molars. The WaveOne(™) system was associated with shorter instrumentation time.

Objetivo: Avaliar clinicamente a condição odontológica de pacientes internados em Unidade de Terapia Intensiva (UTI). Método: Foi realizado estudo exploratório, descritivo e transversal com avaliação clínica odontológica de 50 pacientes internados em UTI do Hospital São Vicente de Paula (João Pessoa/PB). Foram coletados os dados dos prontuários médicos relativos à idade, sexo, fator causal da internação e comorbidades relacionadas a problemas pulmonares. A análise da condição bucal foi qualificada em três categorias: boa (condição aceitável de higiene sem sangramento ao toque ou focos de infecção aparentes); regular (paciente apresentava pouco sangramento ao toque e/ou candidíase observada clinicamente como placas esbranquiçadas sobre mucosa inalterada ou avermelhada, removidas mecanicamente); e ruim (presença de abscessos e candidíase disseminada incluindo orofaringe). Resultados: A idade média dos examinados era de 53,8 (±18,5) sendo 23 (46%) do sexo masculino. As causas das internações de 24 (48,0%) pacientes foram neurológicas e de 26 (52%) por problemas renais, cardíacos, metabólicos, respiratórios e septicemia. Foram registrados quadros de pneumonia em 56% dos pacientes. Quanto à distribuição das condições de saúde bucal, observaram-se porcentagens significativamente maiores (p<0,001) da condição de higiene ruim, comparadas às outras condições. Conclusões: A maioria dos pacientes internados em Unidade de Terapia Intensiva apresentava condição odontológica ruim, e a candidíase foi a infecção mais prevalente.

The pediatric dental approach to the oral cavity of newborns requires special attention, as many aspects are unique and peculiar to this period of life. It is important that pediatricians and pediatric dentists be aware of the characteristics within normal newborn patterns and prepared to make a correct diagnosis of abnormalities at early stages. Congenital eruption cysts (ECs) are rarely observed in newborns, as at this stage of a child’s life, tooth eruption is unusual. This study reports a case of EC treated successfully by monitoring of the lesion, without any surgical procedure. In the 4th month, the lesion had completely regressed, and the deciduous central incisors had erupted without problems. The clinical and radiographic monitoring of ECs in newborns seems to be a satisfactory management procedure, similar to what is recommended for older children.How to cite this article: de Oliveira AJ, Silveira MLG, Duarte DA, Diniz MB.
