The interdental papilla plays a critical role in maintaining both the esthetic and functional integrity of the periodontium. Although the relationship between the papilla presence and the contact point-bone crest distance is well established, the impact of vertical bone defect morphology-common in periodontitis-remains largely unexplored. To assess the relationship between the loss of interdental papilla height and three site-specific factors-vertical bone defect morphology, probing depth, and papilla base width-in patients with periodontitis. Ten periodontitis patients contributing 28 interdental papillae adjacent to vertical bone defects were included. The recorded parameters included probing depth, papilla base width, and loss of papilla height. Intraoperative measurements of defect depth, mesiodistal width, and buccolingual width were also obtained. Patient-level variables, such as age, sex, oral hygiene, and gingival phenotype, were not controlled or included in the analysis, due to the small number of participants and the study's focus on defect-level characteristics. Spearman's rank correlation was used due to non-normal data distribution. A moderate positive association was observed between the probing depth and loss of papilla height (ρ = 0.353), approaching but not reaching statistical significance ( = 0.066). Weak, non-significant associations were found with the remaining parameters ( > 0.05). Although no statistically significant associations were found, observed trends may indicate site-specific influences on the loss of papilla height. These preliminary findings highlight the need for further research with larger, well-characterized cohorts to better understand the factors affecting papilla stability in periodontitis.
龈乳头在维持牙周组织的美学和功能完整性方面起着关键作用。尽管龈乳头的存在与接触点至牙槽嵴顶距离之间的关系已得到充分证实，但牙周炎中常见的垂直骨缺损形态的影响在很大程度上仍未得到探索。为了评估牙周炎患者龈乳头高度丧失与三个特定部位因素——垂直骨缺损形态、探诊深度和龈乳头基部宽度之间的关系。纳入了10名牙周炎患者，这些患者有28个与垂直骨缺损相邻的龈乳头。记录的参数包括探诊深度、龈乳头基部宽度和龈乳头高度丧失。还获得了术中缺损深度、近远中宽度和颊舌宽度的测量值。由于参与者数量较少且研究重点在于缺损水平特征，因此未对患者层面的变量（如年龄、性别、口腔卫生和牙龈表型）进行控制或纳入分析。由于数据分布不呈正态，因此使用了Spearman等级相关性分析。观察到探诊深度与龈乳头高度丧失之间存在中度正相关（ρ = 0.353），接近但未达到统计学显著性（P = 0.066）。与其余参数的相关性较弱且无统计学意义（P > 0.05）。尽管未发现统计学上的显著相关性，但观察到的趋势可能表明特定部位对龈乳头高度丧失有影响。这些初步发现凸显了需要对更大规模、特征明确的队列进行进一步研究，以更好地了解影响牙周炎中龈乳头稳定性的因素。
