The presence of any age-related differences in gingival pigmentation associated with smoking, particularly in a young population, remains to be fully investigated. The purpose of this study was to determine the age-related differences in smoking gingival pigmentation. Gingival pigmentation was analyzed using the gingival melanosis record (GMR) and Hedin's classification with frontal oral photographs taken at 16 dental offices in Japan. Participants were categorized into 10-year age groups, and their baseline photographs were compared. In addition, to evaluate the effect of smoking cessation on gingival pigmentation, subjects were divided into a former smoker group (stopped smoking) and current smoker group. A total of 259 patients 19 to 79 years of age were analyzed. People in their 30s showed the most widespread gingival pigmentation. In addition, subjects in their 20s showed a weak effect of smoking cessation on gingival pigmentation. These findings suggested that the gingival pigmentation induced by smoking was more remarkable in young people than in middle-aged people. This information may be useful for anti-smoking education, especially among young populations with a high affinity for smoking.
与吸烟相关的牙龈色素沉着是否存在任何年龄差异，尤其是在年轻人群中，仍有待充分研究。本研究的目的是确定吸烟引起的牙龈色素沉着的年龄差异。使用牙龈黑素沉着记录（GMR）和赫丁分类法，通过在日本16家牙科诊所拍摄的口腔正面照片对牙龈色素沉着进行分析。参与者被分为10岁年龄组，并比较他们的基线照片。此外，为了评估戒烟对牙龈色素沉着的影响，将受试者分为既往吸烟者组（已戒烟）和当前吸烟者组。共分析了259名年龄在19至79岁之间的患者。30多岁的人牙龈色素沉着最为普遍。此外，20多岁的受试者显示戒烟对牙龈色素沉着的影响较弱。这些发现表明，吸烟引起的牙龈色素沉着在年轻人中比在中年人中更明显。这些信息可能有助于开展戒烟教育，尤其是在对吸烟有高度亲和力的年轻人群中。
