前牙氧化锆全瓷冠粘固前排龈对牙周组织的影响
|
摘要
目的:比较分析前牙全瓷冠粘固前排龈与否对牙周健康的影响。方法:选择前牙全瓷冠美学修复患者100例,分为粘固前进行排龈组和不进行排龈组,每组各50例。对两组患者牙周改良菌斑指数、改良龈沟出血指数及探诊深度进行跟踪随访,并对结果进行统计学分析。结果:经粘固后所有患者均分别于1、3及6个月复查,两组菌斑指数、探诊深度在1个月及3个月后对比,差异无统计学意义;而6个月后两组对比差异具有统计学意义(P<0.05)。改良龈沟出血指数在粘结后1个月时,两组对比差异无统计学意义,而3个月及6个月后两组对比差异均具有统计学意义(P<0.05)。结论:前牙全瓷修复体粘固前排龈可有效预防牙周病,减少牙周损伤。
Objective: To compare the effects of periodontal tissue between gingival retraction or not before the cementation of zirconia ceramic crowns on anterior teeth. Methods: Follow up and measure the meliorated plaque index( mPLI),meliorated sulcus bleecling index( m SBI) and probing depths of two groups that each group with 50 patients,who were division by gingival retraction or not before the cementation of zirconia ceramic crown. Results: Reexamined all the patients after cementation in 1,3 and 6 months. There were no statistically significant difference between two groups in the m PLI and probing depths after 1 month and 3 months respectively. But there was statistically significant difference after 6 months( P< 0. 05). There was no statistically significant difference between two groups in the m SBI after 1 month,but there were statistically significant difference after 3 and 6 months,respectively( P < 0. 05). Conclusion: The technology of gingival retraction before the cementation of zirconia ceramic crowns on anterior teeth,which can prevent periondontal disease,and release the damage of periondontal tissue.
