Abstract: The aim of this study was to test accuracy and reliability of a partial protocol (PP) of oral examination involving the permanent first molars. This cross-sectional study was carried out in two stages. First, a cross-sectional study was performed in a representative sample of 1,211 children using DMFT-index in a full-mouth protocol (FM). A PP was simulated from FM data using only data from the permanent first molars. A second part was performed with 202 children examined by a gold standard examiner (FM) and three dentists using the PP to assess its reliability. Accuracy of PP was assessed by sensitivity/specificity/predictive positive and negative values. Inter-examiner reliability in comparison with gold standard examiner was assessed using weighted kappa. The prevalence of dental caries observed using DMFT index was 32.4% and was 30.2% for PP . The PP presented high sensitivity (93.1%; 95%CI: 91.5-94.5), showing similar magnitude of association’s measures for all associated factors investigated. When compared with the gold standard FM examination, all examiners obtained high parameters of sensitivity and specificity (around 90%). Predictive negative values were higher than predictive positive values for the examiners. This study showed that this partial protocol involving the permanent first molars is accurate and reliable as a screening tool to assess dental caries prevalence and associated factors in schoolchildren.
