Abstract

Background: A study was made of the clinical periodontal changes and buccal cortical bone modifications using cone-beam computed tomography (CBCT) in anterior maxillary teeth with chronic apical periodontitis one year after periapical surgery with submarginal incision.

Material and methods: A prospective case series analysis was made of anterior teeth subjected to apical surgery and submarginal incision with a follow-up period of 12 months. Clinical periodontal parameters were recorded, along with tomographic measurements of the buccal cortical bone and volume of the lesion (in mm3) before and one year after surgery. Success was assessed based on the clinical and tomographic data.

Results: Thirty-six anterior maxillary teeth from 36 patients with a mean age 43.1 years were enrolled in the study. One year after surgery, mean gingival recession was found to be 0.19 mm with a clinical attachment loss of 0.28 mm. Marginal bone loss was 0.25 mm. The thickness of the buccal cortical bone decreased at all three measurement points, with the greatest decrease being observed at 3 mm from the bone crest (0.58 mm). The distance from the apex to the buccal cortical bone (depth of the apex) decreased 0.59 mm at one year. The clinical parameters (clinical attachment level and probing depth) were not correlated with the tomographic measurements (cementoenamel junction-bone crest distance). The mean lesion volume was 457 mm3 at baseline versus 28.4 mm3 one year after surgery, representing a decrease of 93.8% in 12 months. The success rate at one year postsurgery was 94.4%.

Conclusions: One year after apical surgery of anterior maxillary teeth with submarginal incision, only minimal clinical periodontal and tomographic changes are observed, with no clinical relevance. The mean lesion volume decreased 93.8%, and the success rate was 94.4%.

36颗上颌前牙根尖周手术后1年牙周及层析参数的变化。
背景:应用锥形束计算机断层扫描(CBCT)研究慢性根尖牙周炎患者在根尖周缘下切口手术后1年的临床牙周变化和颊皮质骨改变。材料与方法:对行根尖手术及缘下切口的前牙进行前瞻性病例系列分析,随访12个月。记录临床牙周参数,以及术前和术后一年颊皮质骨的断层扫描测量和病变体积(mm3)。根据临床和断层扫描数据评估手术成功与否。结果:36例患者的36颗上颌前牙被纳入研究,平均年龄43.1岁。术后一年,平均牙龈退缩0.19 mm,临床附着损失0.28 mm。边缘骨丢失0.25 mm。颊皮质骨厚度在三个测量点均下降,在距骨嵴3 mm处下降幅度最大(0.58 mm)。从牙尖到颊皮质骨的距离(牙尖深度)在一年内减少0.59 mm。临床参数(临床附着水平和探探深度)与层析测量(牙骨质-牙釉质连接-骨嵴距离)无关。基线时的平均病变体积为457 mm3,而术后一年的平均病变体积为28.4 mm3,在12个月内减少了93.8%。术后1年成功率为94.4%。结论:上颌前牙边缘下切口根尖手术后1年,牙周及体层扫描变化很小,与临床无相关性。平均病灶体积缩小93.8%,成功率94.4%。
