ABSTRACT
AIM:
The aim of this 5-years longitudinal study was to investigate the pattern and rate of periodontal attachment loss (PAL) progression in an urban population in South Brazil.METHODS:
In 2001, a multistage probability sampling strategy was used to derive a representative sample of 1,465 dentate individuals from Porto Alegre, Brazil. Five years later, 697 dentate individuals (294M/403F, mean age 37.9 ± 13.3) were available for follow-up. PAL was assessed by calibrated examiners using a full-mouth protocol. Estimates of proximal PAL progression and standard errors (SE) are reported.RESULTS:
Fifty-six per cent (SE 1.9) and 36% (SE 1.8) of subjects showed PAL progression ≥3 mm affecting ≥2 and ≥4 teeth respectively. PAL progression ≥3 mm was mostly localized affecting 3.8 (SE 0.2) teeth and 5.7 (SE 0.3) sites. Annual PAL progression was, on average, 0.3 mm (SE 0.01). Significant differences in PAL progression were observed according to age, gender, race and socioeconomic status. PAL progression increased with age reaching the highest progression rate in the 40-49 years cohort, and then decreased in older age groups. PAL progression was consistently higher among males and non-Whites than females and whites.CONCLUSION:
A large proportion of this urban Brazilian sample was affected by PAL progression underscoring the need for health promotion initiatives aiming at preventing progression of destructive periodontal disease.
