The purpose of the study was to investigate if the presence of vertical destruction in proximal sites influences periodontal status and healing in adjacent sites in the same proximal space without vertical destruction. The investigation was conducted as a retrospective study on a 3-year consecutive referral population of periodontitis-prone patients based on full-mouth oral radiographic examinations, probing pocket depth registrations and plaque scores. The analyses were performed by using regression analyses on a final sample of 1169 (periodontal status) and 1051 (periodontal healing) proximal sites in 163 patients. The relative radiographic attachment level (RRAL) in proximal horizontal sites did not depend on the type of destruction, vertical or horizontal, in the adjacent proximal sites. However, after non-surgical treatment, pocket-depth reduction in proximal sites with horizontal destruction was significantly reduced in the presence of a vertical destruction in the adjacent proximal site compared to the corresponding sites adjacent to a horizontal defect. It was concluded that marginal periodontal healing in proximal sites with horizontal destruction is impaired by the presence of a vertical destruction in the adjacent proximal site.
本研究的目的是调查近端部位垂直性破坏的存在是否会影响同一近端间隙中无垂直性破坏的相邻部位的牙周状况和愈合情况。该调查是一项回顾性研究，基于全口口腔X光检查、探诊深度记录和菌斑评分，对连续三年前来就诊的易患牙周炎患者群体进行研究。分析是通过对163例患者的1169个近端部位（牙周状况）和1051个近端部位（牙周愈合）的最终样本进行回归分析来进行的。近端水平部位的相对放射学附着水平（RRAL）并不取决于相邻近端部位破坏的类型，垂直性或水平性。然而，在非手术治疗后，与相邻水平缺损部位对应的部位相比，相邻近端部位存在垂直性破坏时，水平性破坏近端部位的探诊深度减少显著降低。得出的结论是，相邻近端部位存在垂直性破坏会损害水平性破坏近端部位的边缘牙周愈合。
