Introdução: O compósito tem se tornado o material de primeira escolha
aquando da realização de uma restauração dentária anterior essencialmente
por motivos estéticos. O estudo da qualidade das restaurações efectuadas
permite a identificação de possíveis erros na técnica e manipulação do
material que podem ser facilmente eliminados.
Objetivo: Este estudo objectivou a descrição e avaliação retrospetiva e
prospetiva do desempenho clínico de restaurações Classe II com compósito,
realizadas por alunos de Medicina Dentária, na Clínica Universitária da
Universidade Católica Portuguesa.
Materiais e métodos: Estudo observacional prospetivo da qualidade clínica
de 12 restaurações de Classe II com compósito realizadas na Clínica
Universitária da Universidade Católica Portuguesa – Centro Regional das
Beiras com controlo a 6 meses – Grupo 1. Paralelamente realizou-se um
estudo observacional retrospetivo do desempenho clínico de 20 restaurações
de Classe II com compósito realizadas na mesma Clínica Universitária com 2
anos – Grupo 2. A avaliação clínica seguiu os parâmetros da United States of
Public Health System (USPHS).
Resultados:. No grupo 1 não se observaram diferenças estatisticamente
significativas nos parâmetros da USPHS entre os dois momentos de
avaliação. Os parâmetros avaliados encontraram-se inalterados ao fim de 6
meses.
No grupo 2, relativamente à reprodução de cor, o valor bravo foi atribuído a
45,0% das restaurações, o valor alfa a 35%, e 20% tiveram má avaliação.
20% das restaurações apresentavam cárie secundaria. Alusivamente à
descoloração da margem cavo-superficial, 65,0% obteve uma avaliação
satisfatória e 30% excelente, 5,0% encontravam-se insatisfatórias. No
parâmetro contorno, 70,0% das restaurações se encontrava excelente e 30%
satisfatórias. Relativamente à integridade da margem, 55,0% das
restaurações estavam excelentes, 40,0% satisfatórias e 5,0% insatisfatórias. Conclusões: A restaurações avaliadas aos 6 meses apresentaram-se todas
com sucesso clínico. Aos 2 anos os parâmetros com maior taxa de insucesso
foram a incidência de cárie e reprodução da cor.
Introduction: The composite is currently recognized as the material of choice on the day of a dental restoration, primarily for aesthetic reasons. The study of the quality of the restorations made allows the identification of potential errors in the technique and manipulation of the material which can be easily eliminated. Objective: The aim of this study was to do the description and retrospective and prospective evaluation of the clinical quality of Class II composite restorations, performed by students of Dental Medicine, at the University Clinic of Universidade Católica Portuguesa. Methods: Observational prospective study of the clinical performance of 12 Class II restorations with composite resins performed at the University Clinic of Universidade Católica Portuguesa – Centro Regional das Beiras and control at 6 months – Group 1. In parallel holds up a retrospective observational study of the clinical performance of 20 Class II restorations with composite resins made in the same University Clinic with 2 years. The clinical evaluation follows the parameters of the United States Public Health System (USPHS). Results: In group 1 there were no statistically significant differences in the parameters of the USPHS between the two time points. Almost all parameters were excellent in all restorations. The parameters evaluated were found unchanged after 6 months. In group 2, on the color reproduction, suficient value was attributed to 45.0% of restorations, the alpha value of 35% and 20% had bad evaluation. 20% of the restorations had secondary caries. Allusively discoloration margin cavosurface, 65.0% achieved a satisfactory evaluation and 30% excellent, 5.0% were unsatisfactory. In parameter contour, 70.0% of the restorations was in excellent and 30% satisfactory. Regarding integrity margin, 55.0% of the restorations were excellent, satisfactory 40.0% and 5.0% unsatisfactory. Conclusions: The restorations evaluated at 6 months were all presented with clinical success. At 2 years, the parameters with higher failure rate were the incidence of caries and color reproduction
