Resumo

Resumo: Objetivo: Caracterizar os Biótipos Periodontais (BP) por meio de fotografias, além de verificar a concordância com o método clínico de determinação, bem como com diferentes profissionais em Odontologia.

Material e método: A avaliação clínica intra-bucal de 34 pacientes (n=34) e verificação de fotografias padronizadas foram realizadas para caracterização dicotômica do BP em fino e espesso. A avaliação subjetiva, por meio da fotografia, foi comparada ao método clínico da transparência à sondagem. A determinação do BP por meio de fotografias foi realizada através da aplicação de um questionário contendo três categorias (fino, espesso e intermediário), direcionadas a 90 cirurgiões-dentistas divididos igualmente em três grupos: clínicos gerais, periodontistas e protesistas. A concordância em ambas as comparações foi avaliada por meio do Teste Kappa, além dos testes de sensibilidade e especificidade.

Resultado: Na comparação entre o método clínico e o fotográfico, não houve concordância (K = 0,264, p = 0,113). Na comparação entre os grupos dos profissionais, foi encontrada uma baixa concordância (kappa = 0,160; p<0,05) entre os periodontistas e protesisas, bem como entre protesistas e clínicos gerais (kappa = 0,110; p = 0,142). Houve maior concordância, ainda que fraca, entre periodontistas e clínicos gerais (kappa = 0,291; p = 0,00). O questionário obteve um valor de sensibilidade e especificidade maior para o diagnóstico do BP espesso.

Conclusão: A avaliação clínica do paciente por meio dos parâmetros clínicos ainda é necessária para caracterizar o BP, visto que a determinação usando-se análise visual por meio do fotografia, independentemente da especialidade, não foi efetiva, embora o BP espesso tenha sido o mais facilmente identificado.

Abstract

Abstract: Objective: To characterize the Periodontal Biotypes (PB) through photographs and verify the agreement with the clinical method of determination as well as with different Dental professionals.

Material and method: Standardized photographs and intraoral clinical evaluation of 34 patients (n = 34) were performed for dichotomous characterization of PB in thin and thick. The subjective assessment, through photography, was compared to clinical method of probing transparency. The PB determination by photographs was performed through the application of a questionnaire containing three categories (thin, thick intermediate) directed to 90 dental professionals. They were equally divided into 3 groups: general practitioners, periodontists and prosthodontists. The concordance in both comparisons was evaluated through the Kappa Test, in addition to the sensitivity and specificity tests.

Result: In the comparison between the clinical and the photographic method, there was no agreement (K = 0.264, p = 0.113). However, in the comparison between the groups of professionals, a low agreement (kappa = 0.160; p <0.05) was found between periodontists and prothesis, as well as between prosthesis and general practitioners (kappa = 0.110; p = 0.142). Greater agreement, although weak, between periodontists and general practitioners (kappa = 0.291, p = 0.00). The questionnaire obtained a higher sensitivity and specificity value for the diagnosis of thick PB.

Conclusion: The evaluation of patients through clinical parameters is still necessary to characterize PB, since the determination using visual analysis using photography, regardless of specialty, was not effective, although thick PB was the most easily identified.
