Evaluation of Different Methods for the Diagnosis of Primary Caries Lesions

Evaluation of Different Methods for the Diagnosis of Primary Caries Lesions: Study Protocol for a Randomized Controlled Clinical Trial

According to the World Health Organization (WHO), dental caries is considered one of the major pediatric health problems worldwide, due to its high prevalence and incidence. Therefore, the early diagnosis of caries lesions is a fundamental procedure for building the treatment plan, aiming at prevention, minimal intervention and the promotion of oral health. The present study aims to evaluate, through a randomized and controlled clinical study, which is the best strategy for diagnosing primary caries lesions located in the interproximal region in individuals aged from 4 to 10 years. Diagnostic methods will be analyzed and compared: visual clinical examination using the International Caries Detection and Assessment System (ICDAS), iTero Element 5D System (intraoral scanner with NIRI technology) and bitewing radiography (BWX). All evaluations will be carried out by 02 examiners. The examiners will be trained and calibrated to use the visual and radiographic criteria, and also to use the iTero 5D intraoral scanner, following the manufacturer's guidance.
