Periodontitis prevalence and associated factors: a comparison of two examination protocols.
Article in Acta odontologica latinoamericana : AOL, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The fact that there are different epidemiological definitions of periodontitis and different evaluation protocols affects the estimate of periodontitis prevalence and of the influence of associated factors. The gold standard for periodontal examination is full-mouth record assessing CAL and PD. However, there are not always sufficient human and financial resources available to apply such assessment for epidemiological surveillance systems.
aimThis study was conducted to compare different protocols and definitions of periodontitis for assessing prevalence and the impact of related factors in adult patients who requested care at the School of Dentistry, UdelaR. MATERIALS AND
methodThis was a cross-sectional study of 410 subjects with a high burden of disease in terms of NCDs and periodontitis. Clinical examination evaluated PD in all teeth and CAL in the CPI sextants (WHO 2013). Four periodontitis criteria were defined based on two examination protocols (WHO 2013 and WHO 1997) and two definitions of epidemiological case. Comparisons were made taking the 2013 WHO protocol as a reference.
resultsComparison of the two examination protocols showed that prevalence was underestimated when the WHO 1997 protocol was used to define moderate-severe and severe periodontitis, by 20% and 60%, respectively.
conclusionsWhen the severity of periodontitis was not considered, the WHO 2013 protocol did not provide more information on what factors increase the chance of periodontitis. However, when severity was considered, the associated factors were different. Consequently, in a small population, it would be worth using the WHO 2013 protocol, which is the closest to the full-mouth gold standard criterion.
