Development of clinical criteria for the evaluation of indirect restorations.

OBJECTIVE: To 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 METHODS: The 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. RESULTS: Cohen'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%. CONCLUSION: The UERJ criteria is a valid instrument for evaluating the clinical performance of indirect restorations. CLINICAL SIGNIFICANCE: The 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.
