“…Inequalities in unmet dental needs are particularly evident in Indian groups 14 and in other racial and/or ethnic minorities 15 . However, knowledge of tooth-loss frequency and its risk factors in Indian populations is scarce because of logistical, financial and political constraints 16 . A single study evaluated tooth loss in 12,349 American Indian and Alaska Native adults.…”

“…At the time of this writing, the Brazilian government recognised 240 Indian tribes, who comprised around 900,000 people (or 0.4% of Brazil's population). The Kiriri Indians live in north-east Brazil and comprise an isolated population of approximately 2,182 16 . Access to the area inhabited by this population is challenging, and external influences are limited, as shown by maintenance of the social, cultural and behavioural backgrounds of the population 16 .…”

Access to the area inhabited by this population is challenging, and external influences are limited, as shown by maintenance of the social, cultural and behavioural backgrounds of the population 16 . Healthcare traditions using plant-based medicines and prayers, lack of help with transport for patients from their remote geographical location, poor quality of the public health-care service and high costs of private health care inhibit access to dental services 16 .…”

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 1946–2012, which compared PMPE vs. full mouth periodontal examination (FMPE) protocols for CAL or PD ≥ 4mm or REC ≥ 3mm 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: 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.

Background Based on the 2018 classification, we aimed to determine the prevalence, distribution, and progression of periodontitis in the rural Chinese population without access to dental care. Methods In all, 404 subjects (28.7 ± 8.9 years, M:F = 182:222) were randomly enrolled in 1992 and re‐called in 1996. With the new classification, the prevalence and distribution of stage, grade, and extent were characterized. Stage progression was compared with the progression of clinical attachment loss (CAL) and radiographic bone loss (RBL). Results At baseline, 94.1% villagers suffered from periodontitis, of whom 53.7% were in Stage III/IV. The prevalence of Stage III/IV increased from 18.2% in the age group of 15 to 24 years to 60.9% in 25 to 34‐year‐old group and 88.7% in the 35 to 44‐year‐old group. Significantly more Stage III/IV, generalized, and Grade C periodontitis were found in male villagers than female villagers. In 1996, the prevalence rate of periodontitis increased to 98.5%, with 80.0% in Stage III/IV. Further, 84.2% villagers presented with Grade C periodontitis based on longitudinal ΔCAL. The rate of progression (≥1 site with ΔCAL ≥3 mm) was 63.7%. Stage progression correlated significantly with CAL and RBL progression in Stage I/II, but this association was not found in Stage III/IV. Among subjects with disease progression in Stage III/IV, 90.4% shifted from localized to generalized cases. Furthermore, ceiling effects were observed in Stage III/IV. Conclusions In villagers without access to dental care, 94.1% suffered from periodontitis, with more than half having Stage III/IV disease based on the 2018 classification. The majority cases presented with rapid periodontal progression. Although stage progression correlated significantly with CAL and RBL progression in Stage I/II, ceiling effects existed in Stage III/IV.
