【摘要】 目的观察新型脱敏剂MSCOAT治疗牙颈部牙本质过敏症的短期疗效。方法选取患有牙颈部牙本质过敏症的患者53人,患牙82颗,随机分成MSCOAT处理组和75%氟化钠甘油脱敏剂处理组(对照组),采用可视分级评价法(VAS法)评价患牙脱敏治疗前、后的敏感性,观察治疗后即刻、治疗后1周、1个月、3个月的疗效。结果与治疗前相比,治疗后即刻、1周、1个月、3个月时MSCOAT治疗组患牙的敏感性显著降低,其VAS降低值明显多于对照组(P<0.001),即MSCOAT脱敏效果优于对照组。结论脱敏剂MSCOAT的脱敏效果优于75%氟化钠甘油脱敏剂,是一种临床疗效较好的治疗牙颈部牙本质过敏症的脱敏剂。更多还原

【Abstract】 Objective To investigate the effects of desensitizer MS COAT on dentine hypersensitivity of dental cervix.Methods Eighty-two teeth with dentine hypersensitivity of dental cervix in 53 patients were selected in this study.The teeth were divided into two groups,desensitizer MS COAT-treated group and 75% sodium fluoride glycerin(NAF) treated-group(control).The sensitivity of teeth was evaluated by visual analogue scale method(VAS) before treatment,immediate after treatment,1 week,1 month and 3 months after treatment.Results Compared with pre-treatment,the sensitivity of teeth at immediate,1 week,1 month and 3 months after treatment decreased significantly in desensitizer MS COAT-treated group.The values of VAS in MS COAT-treated group were significantly greater than those of control group(P<0.001).Conclusion The treatment effect of MS COAT on dentine hypersensitivity of dental cervix was better than that of NAF.The desensitizer MS COAT has better effect on dentine hypersensitivity.更多还原
