摘要

简介:牙周组织的再生总是很难实现,无论所有的进展。在改进的过程中,人们尝试和测试了各种材料。本研究旨在评估骨内缺损易移植晶体的再生潜力,包括临床和影像学。方法:本研究于2015年10月- 2015年10月在龙塔口腔科学与研究学院进行。骨内口袋大于5mm和垂直骨丢失的影像学证据从15例患者中选择,每个患者有两个部位。选择的部位随机分为试验点:开放皮瓣清创(OFD)与易于移植的CRYSTAL和对照部位(OFD)。评估的临床参数包括牙菌斑指数、牙龈指数、探查袋深度、相对附着水平和术后基线、3个月和6个月的牙龈退缩。在基线、3个月和6个月时记录的x线摄影参数是缺陷填充和缺陷填充百分比。数据用SPSS v.20进行分析。结果:在6个月时,与基线相比,临床和放射学价值得到改善。菌斑和牙龈指数有统计学意义的降低。两组的平均探测袋深度和相对附着水平的增加均有统计学意义的降低。两组平均牙龈衰退评分均有所增加,但差异不显著。两组缺损补足率及缺损补足率均显著升高,实验组骨补足效果较好。结论:易移植晶体是治疗牙周骨内缺损的一种有潜力的再生材料。

Efficacy of Calcium Phosphate Composite Bone Graft in Treatment of Periodontal Intrabony Defects: Clinico-radiographic Study
Introduction: Regeneration of periodontium is always difficult to achieve regardless of all advancement. In an attempt to refine, various materials have been tried and tested. The present study was carried out to evaluate regenerative potential of easy-graft CRYSTAL in intrabony defects, clinically, and radiographically. Methods: This randomised split-mouth study was conducted at Rungta College of Dental Sciences and Research from 2015 October to 2015 October. Intrabony pockets more than 5 mm and radiographic evidence of vertical bone loss were selected from 15 patients having two sites each. The chosen sites were randomly divided into test sites: open flap debridement (OFD) with easy-graft CRYSTAL and control sites (OFD). The clinical parameters evaluated were Plaque Index, Gingival Index, Probing Pocket Depth, Relative Attachment Level, and Gingival Recession at baseline, three months, and six months postoperatively. Radiographic parameters recorded were Defect Fill and Percentage of Defect Fill at baseline, three months, and six months. Data were analysed in SPSS v.20. Results: At six months, improved clinical and radiographic values were obtained compared to baseline. The plaque and gingival index showed statistically significant reduction. Both groups showed statistically significant reduction in mean probing pocket depth and gain in relative attachment level. Mean gingival recession score was increased in both the group but was not significant. There was significant increase in Defect Fill and Percentage of Defect fill in both groups with better bone fill in test group. Conclusion: Easy-graft CRYSTAL is a potential regenerative material for the treatment of periodontal intrabony defects.
