A population-based cohort study of oral health in South Brazil: The Porto Alegre Study

Abstract

Few population-based cohort studies have been established in Dentistry and this is especially true for Latin America. We conducted a population-based prospective study focusing on oral health in Porto Alegre, south Brazil, and herein we describe its methodology and discuss directions for further research. The cohort was established in 2001 using a multistage probability sample of 1,465 toothed and 121 edentulous subjects. A 5-year follow-up was performed in 2006 that included 755 individuals. The main aim of this study was to determine the pattern and risk factors for periodontal disease progression and tooth loss incidence. A full-mouth protocol was used including periodontal assessments at six sites per tooth. Primary outcomes were periodontal attachment loss and tooth loss. Oral mucosal lesions, dental plaque, gingivitis, supragingival calculus, probing depths, gingival recession, and dental caries were also assessed. This is the first population-based cohort study to focus on periodontal disease in Latin America. Findings will contribute to our understanding of the epidemiology of periodontal disease and provide valuable data for the planning and implementation of preventive and therapeutic strategies.

Partial‐mouth periodontal examination protocol for estimating periodontitis extent and severity in a US population

“…Calibrated dental hygienists examined NHANES subjects using Hu‐Friedy PCP‐2 (Dye, ; Eke et al, ; Haas et al, ) periodontal probe (Hu‐Friedy, Chicago, IL, USA) at mobile examination centers. Each measurement of clinical attachment loss (CAL) and probing depth (PD) was rounded to the lowest whole millimeter.…”

“…There have been about ten national or regional oral health surveys using various periodontal examination protocols, measurement techniques, and case definitions (Dye, ). Some surveys used full‐mouth periodontal examination at six sites per tooth (FMPE) (Aimetti et al, ; Eke et al, ; Haas et al, ), while others used partial‐mouth examination at various sites (PMPE) (Do et al, ; Bourgeois et al, ; Lee et al, ). To overcome these limitations, the Joint EU/USA Periodontal Epidemiology Working Group suggested standards for reporting chronic periodontitis prevalence and severity in epidemiologic studies (Holtfreter et al, ).…”

“…Levantamentos epidemiológicos na área da periodontia demonstram que a gengivite é uma das doenças bucais mais prevalentes nas diferentes populações estudadas. A prevalência de gengivite é alta em todas as populações e pode ser observada desde uma idade precoce [1][2][3][4].…”
