Abstract
This study aimed to assess the prevalence of aggressive periodontitis (AgP), and to investigate the association between demographic, socioeconomic and behavioral risk indicators with AgP in an untreated and isolated young population in Southeastern Brazil. For this cross-sectional survey, 134 subjects aged 12-29 years were selected by a census. Of those eligible, 101 subjects received a full-mouth clinical examination, and were interviewed using a structured written questionnaire. Cases were defined as individuals with 4 or more teeth with attachment loss > 4 mm or > 5 mm in the age groups 12-19 and 20-29, respectively. Overall, 9.9% of the subjects presented AgP (10.3% of the 12-19-year-olds and 9.7% of the 20-29-year-olds). The only risk indicator significantly associated with AgP in this isolated population was a high proportion of sites (> 30%) presenting supragingival calculus [OR = 23.2]. Having experienced an urgency dental treatment was a protective factor for AgP [OR = 0.1]. The authors concluded that this isolated and untreated population from Brazil presented a high prevalence of AgP. Local plaque-retaining factors played a major role in the prevalence of AgP in this isolated population, and should be included in further studies evaluating this destructive periodontal disease form.
Highlights
Aggressive periodontitis (AgP) is a periodontal disease characterized by a rapid progression rate, leading to pronounced tooth loss.[1]
The analysis suggested a significant association between presence of urgency treatment (OR = 0.1 [0.0-0.7]) and a high proportion of sites with supragingival calculus (OR = 23.2 [2.4225.5]) and AgP
The results of the present study demonstrate that AgP was highly prevalent among young individuals of an isolated and untreated Brazilian population
Summary
Aggressive periodontitis (AgP) is a periodontal disease characterized by a rapid progression rate, leading to pronounced tooth loss.[1]. In a general perspective of all epidemiological studies including young subjects, lower prevalence estimates (< 1%) have been found among Caucasian subjects living in developed countries in comparison to subjects living in developing countries (~0.55%).[2] an aspect that hinders the interpretation of epidemiologic data concerning AgP is that the parameters used for assessing identification of cases vary greatly among surveys.[3,4]. Age,[9] certain ethnic groups,[10] low socioeconomic status,[3,11] poor oral hygiene,[12] local plaque-retaining factors[11] and smoking[11,13] have been associated with destructive periodontal disease in young subjects
