Conclusion It seems that the use of flowable composite as a fissure sealing material can slightly increase the retention rate of sealants compared with conventional resin-based sealants
Objectives The aim of this systematic review and meta- analysis was to evaluate fissure sealant retention in clinical studies in which investigators used flowable composites as pit and fissure sealants compared with conventional resin-based pit and fissure sealants .
Microbial microleakage assessment of a new hydrophilic fissure sealant: a laboratory study.
PURPOSE The purpose of this study was to compare microbial leakage of a new hydrophilic sealant with that of a conventional hydrophobic resin-based sealant . METHODS One hundred extracted , caries-free , human maxillary premolars were r and omly divided into five groups . Those in Groups 1 , 2 , and 3 had dry , wet , and artificial saliva-contaminated occlusal surfaces , respectively , and were sealed with a hydrophilic sealant , while those in Groups 4 and 5 had dry and wet occlusal surfaces , respectively , and were sealed with a hydrophobic sealant . A newly design ed microbial penetration method utilizing Streptococcus mutans as an indicator was tested for leakage assessment . Data were analyzed using SPSS 15.0 software , and the significance level was set at α=0.05 . RESULTS The log rank test indicated a statistically significant difference in leakage rates among the five groups . Mantel-Cox log-rank test findings showed that Group 3 had the highest leakage rate , with Groups 2 and 4 having the lowest . There was no statistically significant difference in leakage rate between Groups 2 and 4 . CONCLUSIONS With respect to the limitations of an in vitro study , our findings suggest that hydrophilic sealants are an acceptable alternative to hydrophobic sealants
