There were thin gaps or voids in the hybrid layer between the flowable composite resin and the enamel probably leading to marginal leakage and the adsorption of the germs.
封闭剂与牙釉质的粘接面内存在微小孔隙,不排除边缘微渗漏及致龋菌吸附的可能。
A subsequent study also showed that a thick flowable composite lining contributed to reduced marginal integrity after the thermocycling test.
