摘要
目的：应用Pro-Plus软件定量分析牙周植骨术临床疗效,探讨其客观评价牙槽骨变化的可行性。方法：选择14例牙周炎患者有22处邻间隙骨下袋,牙周基础治疗4-6周后接受牙周植骨术,随机植入脱钙牙本质基质（decalcified dentin matrix DDM）12处和生物活性玻璃陶瓷（bioactive glass ceramic BGC）10处,记录术前、术后3、6个月的牙周临床指标,并采用Pro-Plus软件对其平行投照根尖片中骨缺损区邻间隙阴影面积（polygon area PG）和角型吸收最低点至牙根尖外表面长度（tooth root T）进行定量分析。结果：DDM和BGC组术后3、6个月时的牙周探诊深度（probing depth PD）和临床附着丧失（clinical attachment loss CAL）均较术前明显减少（P〈0.05）。DDM组术后3个月时的PG较术前减少0.77 mm^2,T值增加0.94 mm;6个月时PG减少3.11 mm^2,T值增加1.84 mm。BGC组3个月时的PG较术前减少0.85 mm^2,T值增加1.06 mm;6个月时PG减少3.03 mm^2,T值增加2.17 mm。两组3、6个月时各自的PG以及T变化值有显著性差异（P〈0.05）,而两组间术前、术后3、6个月各项指标均无显著性差异。Pro-Plus软件分析稳定点测量值一致性检验ICC值均大于0.8（α〉0.4）。结论：DDM和BGC植入骨下袋均能促进牙周附着恢复和骨组织修复,在平行投照根尖片具有较高一致性情况下,Pro-Plus软件可辅助用于牙槽骨变化的定量分析。
Objective： To investigate the clinical and radiographic changes following periodontal bone graft and to validate Image Pro - Plus software analyzing the effects. Methods： Twenty - two interproximal intrabony defects in 14 periodontitis patients were selected , randomly grafted with decalcified dentin matrix （DDM） in 12 defects and bioactive glass ceramic （BGC） in 10 defects. Clinical measurements and radiographs were taken prosurgery and 3, 6 months post -surgery. The Image Pro- Plus software was used to analyze the area of the dark space （polygon area PG） between two adjacent teeth and the curved measurement of the tooth and root surface from the root apex to the deepest point of angular bone defect （T）. Results： 3 and 6 months after the periodontal bone grafts, the mean probing depth （PD） and clinical attachment loss （CAL） were decreased significantly compared with the baseline in two groups （ P 〈 0.05 ）. The DDM group showed that the decrease of PG changes compared with baseline （ A PG） at 3 months was 0.77 mm^2, and the increase T changes （AT） was 0.94 mm. At 6 months, APG and AT were 3.11 mm^2 and 1.84 mm, respectively. In BGC group, APG and AT were 0.85 mm^2 and 1.06 mm at 3 months, while APG and AT were 3.03 mm^2 and 2.17 mm at 6 months, respectively. Both groups showed significant decrease of a PG and increase of A T at 6 months compared with 3 months （P 〈 0.05 ）. There were no significant differences in all measurements between DDM and BGC groups （P 〉 0.05 ）. Radiographs had a high degree of reliability of the stable land mark ICC 〉 0.8 （ a 〉 0.4）. Conclusion： Both DDM and BGC could improve the clinical attachment gain and bone regeneration within intrabony defects. Image Pro - Plus software allowed quantitative measurement of change in alveolar bone under the consistency condition.
