摘要
目的:比较两种瓷贴面粘结方式,用排龈法和直接抛光法对牙龈上皮损伤的研究。方法:选择于2016年2-7月来笔者所在医院牙科就诊的需要进行瓷面贴患者34例共92颗牙,患者年龄19~46岁。数字随机分组,分为抛光组(46颗)、排龈组(46颗)。对照组为修复牙左右两侧远中邻牙的健康牙46颗;抛光组为直接树脂贴面粘结;排龈组为在15 min内,排龈线微创排龈后树脂粘结。操作后2周随访,观察、比较各指标探测深度(probing depth,PD)、Mazza牙龈出血指数(mazza index,MI)、菌斑指数(plaque index,PLI)变化情况。操作后1年,再次复诊观察牙龈外形、着色性。结果:粘结操作后2周,与对照组比较,两种操作方式的Mazza牙龈出血指数、菌斑指数均高,差异有统计学意义(P<0.01),探测深度低,差异有统计学意义(P<0.01);而抛光组及排龈组PD、MI、PLI三项指标比较,差异无统计学意义(P>0.05)。术后1年复诊,所有病例均无显著牙龈缩退、着色。结论:两种操作方式在牙龈出血、炎性反应、探测深度方面,都不同程度损伤了牙龈组织,损害了牙龈的健康程度。而在损伤的程度方面,两种操作方式并无明显差异,临床应用中应个性化选择粘结方法,减少牙龈损伤。
bObjective：To compare the effects of gingival drainage and direct polishing on gingival epithelium injury by two kinds of porcelain surface bonding methods.Method：From February 2016 to July 2016,there were 34 cases of porcelain veneer attached to our hospital,including 92 teeth.The age of the patients was 19-46 years old.Digital random grouping was divided into polishing group（46 teeth）,gingival group（46 teeth）.The control group 46 teeth were the healthy teeth of the distal and middle teeth on both sides of the prothetic teeth.The polishing group was bonded with the direct resin veneer,and the gingiva group was bonded in 15 minutes after the gingiva line.After 2 weeks of follow-up,the changes of detection depth（probing depth,PD）,Mazza gingival bleeding index（Mazza index,MI） and plaque index（plaque index,PLI） were observed and compared.1 year after operation,the gingival shape and coloring were observed again.Result：After 2 weeks of bond operation,compared with the control group,the gingival bleeding index and plaque index of the gingiva of the Mazza increased with the 2 operation methods,the differences were statistically significant（P〈0.01）,the depth of detection decreased,the difference was significant（P〈0.01）,while the polishing and gingival groups were compared with the three indexes PD,MI,PLI,the differences were not statistically significant（P〈0.05）.No recurrence of gingival recession or coloration was found in all cases after 1 year of follow-up visit.Conclusion：The two methods of operation in gingival bleeding,inflammatory reaction,detection depth,all of different degrees of damage gingival tissue,damage gingival health.In terms of the degree of injury,there is no significant difference between the two modes of operation,and the method of bonding shall be selected individually in clinical application to reduce gingival injury.
