流动纳米树脂预防性窝沟龋充填
Flowable nano-resin in preventive pit and fissure caries restoration
摘要
Abstract
BACKGROUND: Without use of traditional precautionary expansion, preventive resin restorations only remove a small amount of decayed tissue and immediately fill caries with composite resin or glass ionomer materials, while the pit and fissure without caries are prevented using a sealant.OBJECTIVE: To evaluate the clinical effect of Filtek Z350 flowable nano-composite resin (3M, USA) in molar occlusal pit and fissure caries, and to explore a new preventive restoration for pit and fissure caries.METHODS: A total of 350 permanent molars with occlusal pit and fissure caries in 196 patients aged from 6 to 25 years were treated with Filtek 2350 flowable nano-composite resin after the cariated tissue had been removed. The opposite or adjacent teeth also with similar caries in the identical patients were treated with Clinpro TM light cure pit and fissure sealant as the control.RESULTS AND CONCLUSION: After the patients were followed up for 4 years, Filtek 2350 flowable nano-composite resin can exhibit high retention rate and effectively prevent the caries development. There were significant differences in the retention rate and caries incidence between study group and control group within 1-2 years postoperation, but significant differences could be observed within 3-4 years postoperation (P ＜ 0.01 , P ＜ 0.05). Filtek Z350 flowable nano-composite resin can be effectively used to treat and prevent molar pit and fissure caries.关键词
