Objective To compare the performance of partial‐mouth periodontal examination ( PMPE ) protocols with different cut‐off points to the full‐mouth examination ( FME ) in the assessment of the prevalence and extent of gingival bleeding in adolescents. Methods A cross‐sectional study was conducted involving 12‐year‐old adolescents. Following a systematic two‐stage cluster sampling process, 1134 individuals were evaluated. Different PMPE protocols were compared to the FME with six sites per tooth. Sensitivity, specificity, area under the ROC curve ( AUC ), intraclass correlation coefficient ( ICC ), relative and absolute biases and the inflation factor were assessed for each PMPE protocol with different cut‐off points for the severity of gingival bleeding. Results The highest AUC values were found for the six‐site two‐diagonal quadrant (2‐4) (0.97), six‐site random half‐mouth (0.95) and Community Periodontal Index (0.95) protocols. The assessment of three sites [mesiobuccal ( MB ), buccal (B) and distolingual ( DL )] in two diagonal quadrants and the random half‐mouth protocol had higher sensitivity and lower specificity than the same protocols with distobuccal ( DB ) sites. However, the use of DB sites led to better specificity and improved the balance between sensitivity and specificity, except for the two‐diagonal quadrant (1‐3) protocol. The ≥1 cut‐off point led to the most discrepant results from the FME . Conclusion Six‐site two‐diagonal quadrant (2‐4) and random half‐mouth assessments perform better in the evaluation of gingival bleeding in adolescents. However, when a faster protocol is needed, a two‐diagonal quadrant assessment using only MB , B and DL sites can be used with no important loss of information.
