透明冠修复上颌乳切牙龋损效果的临床研究

The effect of strip crown's restoration for dental caries of maxillary deciduous incisor: An in vivo study

目的:随访观察透明冠技术修复上颌乳切牙龋损的临床疗效。方法:选取2014年12月~2015年6月我院口腔科就诊的上颌乳切牙患龋儿童患者38例,共95颗上颌乳切牙;所有患牙均去龋,透明冠修复,18个月后复查修复效果并记录患儿的口腔卫生习惯。结果:累及牙面为1~2个组在边缘密合性、边缘着色、表面质地及继发龋中成功率均略高于累及牙面为3个及以上组,但差异无统计学意义(P>0.05)。非每日刷牙者治疗失败率明显高于每日刷牙者,差异有统计学意义(P<0.05);每次刷牙时间少于1 min者治疗失败率也要高于刷牙时间长者,但差异无统计学意义(P>0.05)。结论:针对乳前牙累及多个牙面的龋损,透明冠是较好的修复选择,但仍需加强口腔卫生,以延长其使用寿命。

Objective： The purpose of this study was assessing the effect of strip crown throught follow-up study on its restoration for dental caries of maxillary deciduous incisor. Methods： Thirty-eight cases of children with dental caries of maxillary deciduous incisors,and 95 maxillary deciduous incisors with dental caries were selected. All the caries were moved thoroughly. Then they were prepared as required,and restored with strip crowns. The effect of restoration for dental caries of maxillary deciduous incisors were observed after 18-month follow-up,and their oral hygiene habits were recorded. Results： No matter which standards were selected,compressing,edge coloring,surface texture or secondary caries,the group’s success ratio whose caries involved 1 ~ 2 tooth faces was a little higher than it whose caries involved 3 or more than 3 tooth faces. How-ever,it was not statistically significant（ P 〉 0. 05）. The group’s failure ratio whose brushing time was less than 1 minute every time was higher than that whose brushing time was longer,but it was also not statistically significant（ P 〉 0. 05）. The failure ratio of some research objects who brushed their teeth not everyday was higher than that who brushed their teeth everyday,and this was statistically significant（ P 〈 0. 05）. Conclusion： The strip crown in repairing extensive dental caries of maxillary deciduous incisors is with effective result,meanwhile the children should still strengthen their oral hygiene habits.
