无创渗透树脂材料修复早期乳牙邻面龋

Noninvasive penetration resin materials repair early stage deciduous caries

背景:乳牙早期邻面龋因解剖位置的原因菌斑不易去除,常规再矿化治疗疗效不佳。目的:观察无创渗透树脂技术治疗乳牙早期邻面龋的临床疗效。方法:选择乳牙邻面早期龋的患牙120颗,随机分为渗透树脂组和流动树脂组,每组60颗,分别应用渗透树脂和流动树脂进行治疗,治疗后1年随访,对患者邻面龋的牙体形态、去除釉质脱矿造成的白垩色斑和色泽稳定性、继发龋和治疗成功率方面进行临床评价。结果与结论:两组患者在充填治疗后1年的疗效检查结果中发现,渗透树脂组邻面龋的牙体形态、去除釉质脱矿造成的白垩色斑以及色泽稳定性、继发龋方面均好于流动树脂组。渗透树脂组的治疗成功率96.7%远高于流动树脂组的76.7%,差异有显著性意义(P<0.05)。无创渗透树脂材料是目前阻断龋病发展简便高效的方法。

BACKGROUND： Due to the anatomical location of early deciduous caries, plaque is difficult to remove, and the effect of conventional remineralization therapy is poor. OBJECTIVE： To observe the clinical effect of noninvasive penetration resin for the treatment of early deciduous caries. METHODS： 120 teeth with early deciduous caries were collected and divided into penetration resin groupand flowable resin group, 60 teeth in each group. The teeth were treated with penetration resin and flowable resin respectively. The tooth morphology of caries, enamel demineralization removing caused chalk stains and color stability, secondary caries and treatment success rate were evaluated at 1-year follow-up after treatment. RESULTS AND CONCLUSION： The efficacy at 1 year after filling treatment showed that tooth morphology of caries, enamel demineralization removing caused chalk stains and color stability, and secondary caries in the penetration resin group were better than those in the flowable resin group. The treatment success rate in the penetration resin group （96.7%） was significantly higher than that in the flowable resin group （76.7%）, and the difference was significant （P 〈 0.05）. Noninvasive penetration resin material is the simple and efficient method to prevent the development caries.
