目的探计两种酸蚀剂对牙髓刺激的敏感及效果,以期对临床治疗有所指导。方法对临床上分别有浅龋、中龋的患者进行实验;浅龋的患者分别采用全酸蚀和瞬息万酸蚀的方法进行树脂充填窝洞,中龋和深龋的患者一样采用全酸蚀和自酸蚀两种方法进行充填龋洞进行实验分析。结率浅龋中龋、深龋进行全酸蚀技术充填的患牙对牙髓刺激性的敏感性较强,而使用自酸蚀技术进行龋洞充填的患牙对牙髂刺激的敏感性较弱。结果对于两种酸蚀剂分别对浅龋、中龋、深龋的患牙进行比较。自酸蚀技术对浅、中、深龋的牙髓刺激一般敏感较轻,而全酸蚀技术对浅、中、深龋的牙髂刺激较敏感。
Objective To explore the sensitivity and effect of two kinds of acid etchants on pulp stimulation in order to guide the clinical treatment. Methods The patients with light caries and caries were studied in the clinic. The patients with superficial caries were treated with all-acid etching and instantaneous allodynia respectively, And self-etching two methods for filling cavities for experimental analysis. The rate of dental caries in the light caries, caries-bearing deep tooth caries is more sensitive to dental pulp irritation, while the use of self-etching technology for dental caries filling of the teeth is more sensitive to dental iliac stimulation weak. Results For the two types of etchant, the teeth with shallow caries, middle caries and deep caries were compared respectively. Self-etching techniques are generally less sensitive to dental pulp stimulation of shallow, middle and deep caries, and total acid etching is more sensitive to dental iliac stimulation of shallow, middle and deep caries.
