The prevalence and distribution of gingivitis and gingival recession were studied in 820 Nigerians aged 15, 19, 20 and 21 years sampled from Lagos educational establishments. The prevalence of gingivitis was relatively high at all ages. There was a high degree of correlation between the prevalence of gingivitis affecting mouths, papillae and margins. It therefore would appear that in those mouths with gingivitis, the proportion of affected papillae or margins to those not affected varies only within narrow limits. Although the peak prevalance of gingivitis was observed in the 15-year olds, the prevalence of gingival recession was higher in the 21-year-old students than in those aged 15 years. Gingival recession may be a sequel of gingivitis resulting from apical proliferation of the epithelial attachment with destruction of the subjacent periodontal tissues. Hence gingivitis should be distinguished from gingival recession in its prevalence and distribution.
对从拉各斯教育机构抽取的820名年龄在15岁、19岁、20岁和21岁的尼日利亚人进行了牙龈炎和牙龈退缩的患病率及分布情况研究。各年龄段的牙龈炎患病率都相对较高。影响口腔、乳头和边缘的牙龈炎患病率之间存在高度相关性。因此，在患有牙龈炎的口腔中，受影响的乳头或边缘与未受影响的乳头或边缘的比例似乎仅在狭窄范围内变化。虽然牙龈炎的患病率在15岁人群中最高，但21岁学生的牙龈退缩患病率高于15岁的学生。牙龈退缩可能是由于上皮附着向根尖方向增生并破坏下方牙周组织而导致的牙龈炎后遗症。因此，牙龈炎在患病率和分布上应与牙龈退缩相区分。
