AIM: To describe changes in gingival recession (GR) at buccal and palatal sites in adults over an average follow-up of 4 years.
MATERIALS AND METHODS: Baseline data were obtained from a multistage probabilistic representative sample of 1023 individuals aged ≥35 years from Porto Alegre, Brazil. Buccal and palatal/lingual GR were analysed.
RESULTS: 402 individuals (6,862 teeth) were followed. At baseline, 3,356 (48.9%) teeth did not have GR at the buccal site and 1206 developed the condition overtime (incidence =35.9%; 95% CI 32.6-38.9). Percentage of incident teeth was higher among individuals with (42.3%) than those without (29.5%) periodontitis stages III/IV. Also, 38.5% of teeth with proximal attachment loss at follow-up had incident GR compared to 7.6% of those without proximal attachment loss. Incidence of palatal GR was observed in 32.5% of teeth (95% CI 29.7-35.3). Mean buccal and palatal/lingual GR incidence was 2.11 mm and 2.33 mm, whereas buccal and palatal/lingual GR progression equalled 0.40 mm and 0.48 mm. The prevalence of GR ≥3 mm increased in individuals with (from 35.9% to 47.4%) and without (from 25.2 to 41.5%) periodontitis.
CONCLUSION: Incidence and progression of GR are high in a general urban Brazilian population of adults.
