Interdental soft tissues play a critical role in pink esthetics. The presence and preservation of the interdental papillae in the esthetic zone is as crucial as the shape and contour of the anterior teeth in achieving an esthetically pleasing smile. The present study determines the association of central papilla recession with gingival and interdental smile line in periodontally healthy patients of different age groups.
The present study included 200 patients equally divided into 21 to 40 years and 41 to 60 years age groups. The clinical and photographic evaluation of the central papilla, with midfacial gingiva, and its relationship with the vermilion border was performed.
In total, 137 patients exhibited presence of central papilla, whilst 63 patients had central papilla recession with variable extent. The male patients predominantly had presence of central papilla in both the age groups, with 86% and 64%, compared with 74% and 50% in females, respectively. High gingival smile line was seen in the majority of the patients (62%), and this trend was similar to high interdental smile line (82% of the patients).
Esthetics is affected in individuals having papilla recession along with high gingival smile line and interdental smile line as compared to individuals with low or cupid bow gingival smile line and interdental smile line.
牙间软组织在牙龈美学中起着关键作用。在美学区域，牙间乳头的存在和保留对于实现美观的笑容与前牙的形状和轮廓同样重要。本研究确定了不同年龄组牙周健康患者中央乳头退缩与牙龈及牙间微笑线之间的关联。
本研究纳入200例患者，平均分为21至40岁和41至60岁两个年龄组。对中央乳头、面部中部牙龈进行了临床和影像学评估，并评估了其与唇红缘的关系。
总共137例患者存在中央乳头，而63例患者有不同程度的中央乳头退缩。两个年龄组中男性患者中央乳头存在率较高，分别为86%和64%，而女性患者分别为74%和50%。大多数患者（62%）出现高牙龈微笑线，这种趋势与高牙间微笑线（82%的患者）相似。
与低牙龈微笑线或丘比特弓牙龈微笑线及牙间微笑线的个体相比，伴有高牙龈微笑线和牙间微笑线且有乳头退缩的个体的美学受到影响。
