Abstract

Objective: To estimate bias associated with partial-mouth periodontal examination (PMPE) protocols regarding estimates of prevalence, severity and extent of clinical attachment loss (CAL), pocket depth (PD) and gingival recession (REC).

Material and methods: A search was made for articles published in English, from 1946 to 2012, which compared PMPE versus full-mouth periodontal examination protocols for CAL or PD ≥ 4 mm or REC ≥3 mm thresholds. PMPE protocols were evaluated for sensitivity of estimates of periodontitis prevalence, relative biases for severity and extent estimates.

Results: A review of the literature identified 12 studies which reported 32 PMPE protocols. Three PMPE protocols which had sensitivities ≥85% and relative biases ≤0.05 in absolute values for severity and extent estimates were as follows: (1) half-mouth six-sites, (2) diagonal quadrants six-sites and (3) full-mouth mesiobuccal-midbuccal-distobuccal (MB-B-DB). Two other PMPE protocols (full-mouth and half-mouth mesiobuccal-midbuccal-distolingual) performed well for prevalence and severity of periodontitis; however, their performance in estimates of extent was unknown.

Conclusions: Among the 32 PMPE protocols listed, the half-mouth six-sites and full-mouth MB-B-DB protocols had the highest sensitivities for prevalence estimates and lowest relative biases for severity and extent estimates.

Keywords: partial-mouth examination protocols; periodontal indices; periodontitis; periodontitis prevalence.
