【摘要】 目的:观察二氧化碳激光治疗仪联合牙齿脱敏剂治疗重度磨耗所致的牙本质过敏症的效果。方法:选取2018年11月-2019年4月本科室收治的重度磨耗所致的牙本质过敏症患者60例,随机分为实验组和对照组各30例,对照组行单纯使用脱敏剂治疗,实验组在对照组的基础上行二氧化碳激光治疗,比较2组患者治疗后即刻、第1个月、第3个月的临床疗效及生活质量。结果:实验组即刻总有效率为96.67%,第1个月的总有效率为83.33%,第3个月的总有效率为80%,均高于对照组的76.67 00%、66.67%、56.67%,差异均有统计学意义(P<0.05)。结论:激光治疗仪联合脱敏剂治疗重度磨耗所致的牙本质过敏症,通过对牙体组织羟磷灰石中水分子的高吸收成功地使牙本质表面发生熔融和再结晶,堵塞牙本质小管从而脱敏,可缓解患者的牙齿刺激疼痛,具有良好的临床效果,值得在临床推广。更多还原

【Abstract】 Objective:To observe the effect of carbon dioxide laser therapy device combined with tooth desensitizer on dentin hypersensitivity caused by severe abrasion.Methods:Sixty patients with dentine hypersensitivity caused by severe abrasion in our department from November 2018 to April 2019 were randomly divided into experimental group and control group.The control group was treated with desensitizing agent alone.The experimental group underwent CO2 laser treatment on the basis of the control group,and compared the clinical efficacy and quality of life of the two groups immediately after treatment,the first month and the third month.Results:The total effective rate was 96.67% in the experimental group,83.33% in the first month,and 80% in the third month,which were higher than the control group’s 76.67 00%,66.67%,56.67.%,the difference was statistically significant(P<0.05).Conclusions:Laser therapy device combined with desensitizer for the treatment of dentin hypersensitivity caused by severe abrasion,through the high absorption of water molecules in the hydroxyapatite of the tooth tissue,the surface of the dentin is melted and recrystallized,and the dentin is blocked.The small tube is desensitized,which can alleviate the patient’s tooth irritation and pain,has a good clinical effect,and is worthy of clinical promotion.更多还原
