摘要

本研究的目的是评估亲水性牙本质引物消除牙本质对热刺激的超敏反应的有效性。8名患者参加了这项研究,共有42颗牙齿因侵蚀、磨损或牙周治疗而出现颈椎敏感。所有牙齿对冷空气和触觉探索都很敏感。所有的测试部位都用水冲洗,风干,并用湿润的棉质布擦拭。然后用刷子在暴露的牙本质上涂上几层牙本质底漆,底漆由n -甲苯甘氨酸-甲基丙烯酸甘油酯和二甲基丙烯酸双苯酯组成。所有患者在治疗后立即用热刺激重新测试这些部位时均报告完全没有疼痛。9个月后,7名患者仍无症状,1名患者对冰有轻微敏感性。结果表明,单次应用亲水性牙本质引物可有效减少或消除牙本质对热刺激的超敏反应,至少持续9个月。

Polymeric sealing of dentinal tubules to control sensitivity: preliminary observations.

The purpose of this study was to evaluate the effectiveness of a hydrophilic dentin primer to eliminate dentinal hypersensitivity to thermal stimuli. Eight patients enrolled in the study, with a total of 42 teeth having cervical sensitivity caused by erosion, abrasion, or periodontal therapy. All teeth were sensitive to cold air and tactile exploration. All test sites were rinsed with water, air-dried, and rubbed with a moist cotton pledget. Several coats of a dentin primer, consisting of N-tolylglycine-glycidyl methacrylate and bisphenyl dimethacrylate, were then applied with a brush to the exposed dentin and light-cured. All patients reported a complete absence of pain when the sites were retested with thermal stimuli immediately after treatment. After a 9-month period, seven patients remained symptomless, and one patient indicated slight sensitivity to ice. It was concluded that a single application of a hydrophilic dentin primer is highly effective in reducing or eliminating dentinal hypersensitivity to thermal stimuli for at least 9 months.
