目的为临床选择牙周基础治疗龈下刮治术的方式提供参考。方法将35例轻中度慢性牙周炎患者随机分为2组,行口腔卫生宣教及全口超声龈上洁治,并填写牙科畏惧量表(dental fear survey,DFS)评估患者畏惧水平。2组患者分别使用Vector治疗仪和P...目的为临床选择牙周基础治疗龈下刮治术的方式提供参考。方法将35例轻中度慢性牙周炎患者随机分为2组,行口腔卫生宣教及全口超声龈上洁治,并填写牙科畏惧量表(dental fear survey,DFS)评估患者畏惧水平。2组患者分别使用Vector治疗仪和P5治疗仪进行龈下刮治术,术后再次填写DFS。治疗前及治疗后1个月监测菌斑指数(plaque index,PLI)、探诊出血(bleeding on probing,BOP)和探诊深度(probing depth,PD)等各项临床指标,监测治疗前后临床指标及患者心理畏惧水平的变化。结果患者使用Vector系统和P5系统进行龈下刮治后各项临床指标均较术前明显改善(P<0.05),2组间BOP和PD变化的差异无统计学意义(P>0.05),PLI的改善Vector组优于P5组(P<0.05)。Vector组治疗后患者DFS得分由51.28±19.61降低为49.16±17.21,差异无统计学意义(P>0.05);P5组治疗后患者DFS得分由49.41±16.14增加至50.82±15.86,差异有统计学意义(P<0.05)。2组DFS得分变化的差异有统计学意义(P<0.05)。结论在轻中度慢性牙周炎龈下刮治术中,Vector系统与P5系统均可获得确切的临床疗效,均不会增加患者在龈下刮治过程中的畏惧水平,而保持患者心理状态的稳定性。展开更多
目的研究Vector系统进行牙周基础治疗的临床效果。方法采用口内自身对照方法,选择58例慢性牙周炎患者,口内A、D区设为试验组,B、C区设为对照组。所有患者行超声洁治后,试验组应用Vector系统行龈下刮治及根面平整术(scaling and root pla...目的研究Vector系统进行牙周基础治疗的临床效果。方法采用口内自身对照方法,选择58例慢性牙周炎患者,口内A、D区设为试验组,B、C区设为对照组。所有患者行超声洁治后,试验组应用Vector系统行龈下刮治及根面平整术(scaling and root planning,SRP),对照组应用Gracey刮治器械行SRP。对2组SRP的治疗时间,SRP前(基线期)及SRP后1、3、6个月的龈沟出血指数、探诊出血、探诊深度及附着水平进行比较,视觉模拟疼痛评级法(visual analogue scale,VAS)评定2组的疼痛程度。结果试验组每区的SRP治疗时间为(25.15±1.35)min,明显短于对照组的(40.11±1.08)min(Z=3.625,P<0.05)。SRP后各观察时点,2组的各项牙周指数较治疗前均有明显改善(P<0.05),但2组间各项牙周指数的差异均无统计学意义(P>0.05)。试验组SRP结束时(Zc=2.356,P<0.05)及治疗后1d(Zc=3.138,P<0.05)的VAS评分明显低于对照组。结论Vector系统能缩短临床操作时间,提高牙周基础治疗舒适度,有效改善慢性牙周炎的临床症状。展开更多
