Development of clinical criteria for the evaluation of indirect restorations

Abstract

ObjectiveTo propose the development and validation of criteria for evaluating the clinical performance of indirect restorations, considering the variables related to the operator, material, and/or patient.Materials and MethodsThe experimental design of this study was divided into three stages. Stage 1: development of the new criteria items by specialists in Prosthodontics. Step 2: creation of the criteria, named UERJ criteria, with the description of the parameters that indicate the quality of the restoration, the possible associated complications, and a detailed description of each classification. As well as the development of a form of variables. Step 3: validation of the UERJ criteria.ResultsCohen's Kappa statistic registered for both intra‐ and inter‐examiner agreements a coefficient >0.91 with a p‐value <0.0001. The validity of the UERJ criteria was evaluated by tests of sensitivity (0.96) and specificity (0.91) and had a satisfactory accuracy (92.7%), a positive (10.99), and negative (0.05) likelihood ratio and high values predictive variables, with positive (PPV) 0.84 (high specificity) and negative (VPN) 0.98 (high sensitivity), with a confidence interval of 95%.ConclusionThe UERJ criteria is a valid instrument for evaluating the clinical performance of indirect restorations.Clinical SignificanceThe UERJ criteria, developed exclusively for the analysis of indirect restorations, elucidates the details necessary to identify the causes of failures and complications of these restorations.
