The purpose of the present investigation was to compare clinical periodontal healing in periodontally involved teeth with and without pulpal pathosis. The investigation was conducted as a retrospective study on a consecutive referral population. The periapical conditions in endodontically involved single-rooted teeth from a selected patient sample were evaluated and correlated with their periodontal healing pattern. Multiple regression analysis of the registered variables showed that initial mean pocket depth and time elapsed after treatment significantly influenced change in pocket-depth. Non-surgical treatment of periodontal pockets exceeding 2.5 mm in teeth with horizontal marginal defects, over the observation period, showed significantly reduced mean pocket depth reduction in teeth with periapical pathology compared to teeth without periapical pathology. It was, furthermore, evident that proximal restorations, abutments for fixed bridges and root fillings with and without dowels did not significantly influence pocket depth reduction in the present material. It was concluded, based on the present results, that a root-canal infection, evident as a periapical radiolucency, if left untreated may in the long term perspective result in retarded or impaired periodontal healing following periodontal therapy and, consequently, should be given appropriate consideration when coordinating endodontic therapy and periodontal treatment.
本研究的目的是比较有和没有牙髓病变的牙周受累牙齿的临床牙周愈合情况。该研究作为一项对连续转诊人群的回顾性研究进行。对选定患者样本中牙髓受累的单根牙的根尖周情况进行评估，并将其与牙周愈合模式相关联。对记录变量的多元回归分析表明，初始平均牙周袋深度和治疗后经过的时间显著影响牙周袋深度的变化。在观察期内，对水平边缘缺损且牙周袋超过2.5mm的牙齿进行非手术治疗，结果显示与无根尖周病变的牙齿相比，有根尖周病变的牙齿平均牙周袋深度减少明显降低。此外，在本研究材料中，明显的是，邻面修复体、固定桥基牙以及有无桩的根管充填对牙周袋深度减少没有显著影响。根据目前的结果得出结论，从长远来看，如果不治疗，表现为根尖周透射区的根管感染可能会导致牙周治疗后牙周愈合延迟或受损，因此，在协调牙髓治疗和牙周治疗时应给予适当考虑。
