To describe changes in gingival recession (GR) at buccal and palatal sites in adults over an average follow-up of 4 years.
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.
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.
Incidence and progression of GR are high in a general urban Brazilian population of adults.
描述成人颊侧和腭侧牙龈退缩（GR）在平均 4 年随访期间的变化。
基线数据来自巴西阿雷格里港多阶段概率代表性样本中的 1023 名年龄≥35 岁的个体。分析了颊侧和腭侧/舌侧 GR。
402 名个体（6862 颗牙）接受了随访。基线时，3356 颗（48.9%）牙在颊侧没有 GR，1206 颗牙在随访期间出现了这种情况（发生率=35.9%；95%CI 32.6-38.9）。患有牙周炎 III/IV 期的个体（42.3%）中出现的牙齿比例高于没有牙周炎的个体（29.5%）。在随访时出现近中附着丧失的牙齿中，有 38.5%发生了 GR，而没有近中附着丧失的牙齿中，只有 7.6%发生了 GR。32.5%的牙齿出现腭侧 GR（95%CI 29.7-35.3）。颊侧和腭侧/舌侧 GR 的平均发生率分别为 2.11mm 和 2.33mm，而颊侧和腭侧/舌侧 GR 的进展分别为 0.40mm 和 0.48mm。患有牙周炎的个体（从 35.9%增加到 47.4%）和没有牙周炎的个体（从 25.2%增加到 41.5%）中，GR≥3mm 的患病率增加。
在巴西一个普通城市成年人群中，GR 的发生率和进展率都很高。
