用光固化粘结剂作牙颈部牙本质敏感症脱敏治疗，临床疗效优于７５％氟化钠甘油糊剂脱敏法。患者年龄３１～６０岁。实验组１２例４６颗患牙，用３７％磷酸酸蚀敏感区３０秒，冲洗吹干，涂光固化粘结剂及光照２０秒各２次。对照组１１例４５颗患牙，用７５％氟化钠甘油糊剂置于敏感区３分钟。检查患牙在治疗后即刻、１月的反应。以患者治疗前后自觉症状改变，探诊有无敏感，喷冷水有无酸痛判定疗效。即刻检查实验组显效牙４０颗，无效６颗，有效率８６９６％；对照组显效牙３４颗，无效１１颗，有效率７５６％，两组ｘ２值１９５，Ｐ＞００５。１月复查实验组显效牙３０颗，无效５颗；对照组显效牙２２颗，无效１２颗，有效率６４７％，两组Ｘ２值４１，Ｐ＜００５。
With light-cured adhesive dentin hypersensitivity treatment for cervical and neck, the clinical curative effect is better than 75% sodium fluoride glycerol paste desensitization method. Patients aged 31 to 60 years old. Experimental group of 12 patients with 46 teeth, with 37% phosphoric acid etching sensitive area 30 seconds, rinse dry, coated with light curing adhesive and light 20 seconds each 2 times. Control group of 45 patients with teeth, with 75% sodium fluoride glycerol paste placed in the sensitive area for 3 minutes. Check the teeth immediately after treatment, January response. Patients with symptoms before and after treatment to change, explore the presence of sensitive, whether to spray cold water to determine the efficacy of pain. Immediately check the experimental group of 40 effective teeth, invalid 6, the effective rate was 86.96%; the control group of 34 effective teeth, ineffective 11, the effective rate was 75.6%, the two groups x2 value of 1 95, P> 0 05 January review of the experimental group marked effective teeth 30, invalid 5; control group marked effective teeth 22, 12 ineffective, the effective rate was 64.7%, two groups X2 value 4 1, P <0 05.
