摘要
目的观察利用超声波技术去除浅、中龋龋洞内的腐质的临床效果。方法随机选取69例患者114颗浅、中龋洞牙齿,随机分成2组,分别用高速涡轮钻去腐法,超声去腐法去腐后充填,观察1年内的疗效。结果高速涡轮钻去腐法去腐后充填的成功率为98.41%,超声去腐后充填的成功率为96.08%。经统计学χ2检验高速涡轮钻去腐法组与超声方法组之间疗效差异无统计学意义。结论超声去腐法去除浅、中龋在临床中应用是可行的。
Objective To observe the Clinical application effects of ultrasonic removing necrotic tissue on enamel caries and superficial caries of dentin.Methods 114 teeth with enamel caries and superficial caries of dentin coming from 69 patients were randomly divided into two groups.One group were used with dental handpieces/burs removing necrotic tissue,the other were used with ultrasonic diamond tips removing necrotic tissue,then both restored by nanometer composite resin.All the patients were followed-up for 1 year to compare the clinical effects.Results The successful ratio of dental handpieces/burs removing necrotic tissue group were 98.41%,ultrasonic removing necrotic tissue group were 96.08%.There was no significant difference between handpieces/burs group and ultrasonic group by chi square test.Conclusion That using ultrasonic removing necrotic tissue on enamel caries and superficial caries of dentin is feasible in clinical application.
