“…Similar to the results of the SBS analysis, the microleakage results in the EG were inferior (12.8%); in contrast, in the CG, little dye infiltration was observed (1.1%). A similar trend has been reported in the literature, in which a few studies have observed microleakage for the self-etch adhesive sealants in a range closer to that of acid-etch sealants 14,15) . However, extremely high microleakage values greater than those observed in our study have also been reported 16) .…”

This study aimed to evaluate the shear bond strength (SBS) and microleakage of a new self-etch adhesive-based fissure sealant (EG) on aprismatic enamel in comparison to conventional fissure sealing with 30 s acid etching (CG). The fissures were sealed according to the manufacturer's instructions. Each group was divided into 3 subgroups: 1-day water storage, 3-month water storage, and 5,000× thermocycling. After measuring SBS using the Ultradent method, failure mode was analyzed. In additional 16 teeth, microleakage was tested using dye penetration method. Pairwise comparisons were analyzed using Mann-Whitney U-Test. Multiple linear regression was performed to assess the factors influencing on SBS. EG had significantly lower mean SBS (4.1 MPa±2.1) than the CG (17.6 MPa±6.4). CG (1.1%) performed significantly better than the EG (12.8%) in microleakage analysis. The tested EG yielded significantly inferior results and its clinical use should be decided after weighing its pros and cons.

“…They attributed the higher microleakage of self-adhesive composite to inability to eliminate the smear layer. Studies comparing the microleakage of selfetch and conventional etch and rinse adhesives have also mainly reported higher microleakage of self-etch adhesives at the enamel margins [25][26][27]. However, Vichi et al…”

Objectives: Application of fissure sealants is a practical method for prevention of occlusal pit and fissure caries. Microleakage is an important factor affecting the success of fissure sealant treatment. This study aimed to assess the microleakage of a self-adhesive flowable composite, a self-adhesive fissure sealant and a conventional fissure sealant in permanent teeth with/without saliva contamination. Materials and Methods: This in vitro, experimental study evaluated 108 extracted human third molars, which were randomly divided into six groups (n=18) of control, Denu-Seal conventional fissure sealant applied on etched enamel with/without saliva contamination, Vertise Flow self-adhesive flowable composite applied on rinsed and dried enamel with/without saliva contamination and Prevent Seal self-adhesive fissure sealant applied on rinsed and dried enamel with/without saliva contamination. Microleakage was assessed using the dye penetration technique and subsequent observation of samples under a stereomicroscope. Data were analyzed using the Kruskal-Wallis and Tukey’s test. Results: Microleakage of the conventional fissure sealant with/without saliva contamination was significantly lower than that of other groups (P<0.05). Conclusion: Microleakage of the conventional fissure sealant is less than that of self-adhesive fissure sealant and self-adhesive composite, irrespective of saliva contamination.

“…However, the effect of the time of contamination during light curing was not considered in the Peng et al 15 and Memarpour et al [16] studies. Basir et al [17] carried out a study on the effect of the different adhesive system on fissure sealant microleakage with or without saliva contamination. They have reported that microleakage was reduced by using bonding systems, although it was not eliminated and sealants without any bonding agent could not tolerate slightest saliva contamination.…”

Background and Aim: One of the important factors in microleakage of fissure sealants is saliva contamination. Researchers believe that applying bonding agents can reduce the microleakage. The present study compared the microleakage of a fissure sealant contaminated with artificial saliva at different curing times with or without using a bonding agent. Materials and Methods: In this in-vitro study, 96 extracted premolars were randomly divided into eight groups. Fissure sealant was applied to all groups; in 4 groups after putting on a bonding agent and in remaining four without a bonding agent. Specimens of each group were contaminated with saliva at different times (5, 10, 15 and 20 seconds) during curing. Then the microleakage of samples was measured. Mann-Whitney and Kruskal-Wallis tests were used to statistically analyze the collected data. Results: No-bonding groups had significantly higher microleakage values than bonding groups. Among bonding groups, the microleakage values were significantly lower when contamination occurred after 15 and 20 seconds of light curing. Amounts of microleakage were similar in no-bonding groups (P=0.39) when contamination occurred at 5, 10 and 15 seconds of curing; however, contamination after 20 seconds led to significantly lower microleakage (P<0.001). Conclusion: The findings revealed that when using the bonding agent, retreatment is not required if contamination occurs after 10 th second of curing; however, retreatment is required when no bonding has been applied, and contamination happens before 20 th s of curing. Thus the isolation is more critical when pits and fissure sealants are applying without using a bonding agent.
