目的:体外比较不同窝沟处理方法,窝沟是否污染,不同封闭材料,不同光照时间对窝沟封闭剂渗透性的影响。方法:48颗离体前磨牙,随机分为16组,每组3颗牙,分别采用不同封闭材料及方法进行窝沟封闭,体视显微镜下观察,对窝沟封闭剂的渗透率进行测定。结果:窝沟封闭材料、窝沟处理方法两种处理因素自身不同水平比较,差异具有统计学意义(P<0.05),窝沟封闭材料和窝沟处理方法之间存在交互作用(P<0.05)。结论:窝沟釉质成形术与封闭剂Helioseal F联合应用进行窝沟封闭具有很好的临床应用价值。
OBJECTIVE: To compare the effects of different pit and fissure treatment methods, fissure pit fouling, different enclosing materials and different illumination time on the fissure sealant permeability in vitro. Methods: Forty - eight ex - molars premolar teeth were randomly divided into 16 groups with 3 teeth in each group. The foramen was closed with different materials and methods. The permeability of fissure sealant was determined by stereomicroscope. Results: The fissure sealant and pit and fissure sealant treatment methods had different statistic significance (P <0.05), there was an interaction between pit fissure sealant and pit fissure treatment (P <0.05) . Conclusion: The fissure sealant with fissure enameloplasty and Helioseal F has good clinical value.
