“…Their prevention is a challenge that can be controlled by non-operative measures especially if implemented early. 1,2 American Academy of Pediatric Dentistry and Cochrane recommend the application of pit-and-fissure sealants on newly erupted posterior teeth so as to reduce the incidence of pit and fissure caries. 3,4 Sealant retention is crucial for it to be effective, and this can be achieved by various factors.…”

“…They can prove to be beneficial compared to the other resin sealants especially in pediatric practices. 2 There have been many in-vitro evaluation studies 7,8 conducted comparing the self-etch sealant with conventional acid etch sealants. The present in-vivo study was thus designed with the focus to clinically evaluate the sealing ability and retention of the self-etching sealant compared to the conventional resin sealant.…”

Background: Self-etching has been shown to be beneficial compared to the other resin sealants especially in pediatric practice. The present in-vivo study was designed to clinically evaluate the sealing ability and retention of the self-etching sealant compared to the conventional resin sealant. The aim was to evaluate and compare the retention and marginal integrity of the self-etch and acid etch sealant materials at three, six and twelve-month follow up. Methods: This was designed a randomized controlled trial, with double blind parallel, split-mouth design. In total, 35 children (70 teeth) between 7 and 10 years of age formed part of the study. Group 1 received acid-etch sealant and Group 2 received self-etch sealants. The study participants and the investigator who performed the statistical analysis were blinded to the treatment allocation. All the samples were evaluated at 3, 6, and 12 months. The inter-group and intragroup comparison were carried out using the Chi-Square test and Friedman test with level of significance set at 5% and the P value less than 0.05. Results: Complete retention of sealants was observed in 34.5% of conventional acid etch (group 1) and 22.9% of self-etch samples (group 2) whereas complete loss of sealants were seen in 11.4% of group 1 and 20% of the group 2 samples and intergroup comparison of retention failure was non-significant (p=0.135). In total, 85.7% of the group 1 and 82.9% of the group 2 samples exhibited good marginal integrity with no clinical changes in the enamel around the margins but this was not statistically significant (p=0.5). Conclusions: Sealants with fewer procedural steps and those which provide adequate retention would be ideal for use in children. Thus, self-etch sealants have been found to be effective and efficient as a sealant in the present in-vivo study. Clinical Trials Registry, India registration: CTRI/2019/03/018343 (29/03/2019).

“…The applicability of flowable composites has increased in recent years, mainly because of their beneficial properties, such as low viscosity, low modulus of elasticity and ease of handling, which helps in the successful placement of the material. Moreover, higher filler particle amounts provide lesser porosity and better wear resistance compared to those of conventional resin pit-and-fissure sealants [ 16 ]. However, clinicians believe that increasing the filler content leads to an increase in the viscosity and lower retention.…”

Background: This study compared conventional-resin-sealant versus nanofilled-sealant retention at different intervals. Methods: A double-blinded split-mouth randomized control trial was performed on sixty-two children aged from six to nine years. Participants with one pair of contralateral permanent first molars with deep fissures or noncavitated carious lesions were randomly selected for sealant application. Conventional resin sealant was applied on one molar and nanofilled sealant on the contralateral molar. Evaluations were performed at one, three, six, twelve and eighteen months to check for retention. The chi-squared test, McNemar test, Wilcoxon signed-rank test and Friedman test were used for statistical analysis. Results: Conventional resin sealant showed complete retention in 91.4%, 86.2%, 74.1%, 62.1% and 55.2% of the teeth, and nanofilled sealant showed complete retention in 89.7%, 81%, 77.6%, 69% and 67.2% of the teeth, at the end of 1 month, 3 months, 6 months, 12 months and 18 months evaluation, respectively. Each sealant exhibited a statistically significant change (p < 0.05) in the retention rate during the evaluation period. However, when both the sealants were compared with each other, there was no statistically significant difference in any phase. At the end of 18 months, caries development was observed in 13.8% of the teeth sealed with conventional sealant, and in 10.3% of the teeth sealed with nanofilled sealant. Conclusion: At eighteen months, the nanofilled resin sealant exhibited complete retention in 12% more teeth than the conventional sealant. However, the difference was not statistically significant. The nanofilled resin sealant yielded an acceptable performance in sealing the occlusal pits and fissures of mandibular permanent first molars, compared to conventional pit-and-fissure sealants.

“…(3,4,5) In 1974 McLean and Wilson introduced glass ionomer cement as a material for sealing the occlusal surface. (7) Currently, different types of sealants are available: with and without filler; transparent and opaque, with color change after polymerization, with and without fluoride. (8,9) The addition of fluoride to these materials aims to achieve a double effect -in addition to creation of a mechanical barrier limiting the accumulation and retention of microorganisms, low concentrations of fluoride in contact with the tooth surface increase fluorapatite and accelerate remineralization.…”

Aim: Comparative assessment of the wear and preventive effect of two materials -conventional sealant and glassionomer cement (GIC), in the coating of sound occlusal fissures of the first permanent molars. Materials and method: The study included 60 teeth in 30 children in the age group of 6 to 9 years. The teeth were diagnosed as "healthy" with code 0 (according to ICDAS II) by visual inspection. The diagnosis was also supported by the SoproLife camera. The teeth were divided into two groups: in 30 teeth the preventive sealing was made with lightcuring sealant 3M Clinpro Syringe refill, in the other 30 teeth with GC Fuji IX GP. The follow-up period was 18 months and assessment and comparison of the abrasion of the used materials and their preventive effect was made. Results: According to the criteria used to assess their abrasion, the two materials show similarly very good results over the follow-up period. In both cases there is no loss of the material thickness, which would decrease their preventive effect. No occlusal carious lesion was reported during the observation period. Conclusion: Both materials are equally effective in preventing occlusal carious lesions in newly erupted first permanent molars. The glass ionomer cement used as a preventive sealant is probably the better material for less cooperative children, given its lower sensitivity to moisture when implementing the application protocol.
