“…A recent study investigated the flexural strength, elastic modulus, and remineralization abilities after 7 days of pH-cycling of bioactive and non-bioactive sealant materials and found that BioCoat TM had the highest amount of fluoride, calcium, and phosphate ions, and the tinniest demineralization area; moreover, they were also superior in terms of their flexural strength and modulus of elasticity [24]. This supports choosing BioCoat TM as the material representing Bio-RBS in this study.…”

“…The company claims that the material releases ionic fluoride, calcium, and phosphate and that it has a similar retention to other RBS [23]. A recent study compared this material to other bioactive materials and found BioCoat TM to have the highest flexural strength, elastic modulus, and remineralization abilities [24]. Another study found inhibition of enamel demineralization with experimental sealants containing bioactive glass in a cariogenic environment and concluded that PFS containing a bioglass filler is a promising dental material to prevent marginal or secondary caries at the marginal gap [25].…”

Background: Sealing occlusal pits and fissures is an effective preventive measure against dental caries. Pit and fissure sealants (PFS) should be strongly bonded to the teeth to prevent partial or complete loss of the sealant, which may limit its preventive effect. Objective: The objective of the study was to compare the microtensile bond strength (μTBS) of bioactive resin-based sealants (Bio-RBS) and resin-based sealants (RBS), with and without the use of a bonding agent, to the enamel of primary and permanent teeth. Methods: One hundred and twenty caries-free primary molar specimens and 120 permanent molar specimens were divided to eight groups (30 specimens per group), both primary and permanent teeth were sealed with a Bio-RBS BioCoatTM (Premier®, Plymouth Meeting, PA, USA) or with a RBS ClinproTM (3M ESPE, Saint Paul, MN, USA), with or without the use of a bonding agent (Prime & Bond NT; Dentsply, Inc., Charlotte, NC, USA). Half the specimens were aged with 5000 thermal cycles, and all specimens were tested for the μTBS and failure mode. Results: The mean μTBS of aged Bio-RBS was higher in permanent teeth than primary teeth, and the aging process reduced the μTBS of RBS more than that of Bio-RBS. Moreover, the addition of a bonding agent improved the μTBS of aged RBS in permanent teeth. Conclusion: We concluded that Bio-RBS exhibit superior μTBS than RBS when applied to permanent teeth.

“…Sample size was calculated using G*power sample size calculator program (3.1.9.6) for Mac. At power equal 95%, α equal 0.05 and effect size (2.1) based on the anticipated mean values of mineral released from the two bioactive sealants according to Fita k et.al (19) and Ibrahim MS et.al (20) . Statistical t test for the difference between two independent means of two groups calculation was used, and the minimal total sample size was (12 teeth), which was increased to (32 teeth) to increase the statistical power.…”

Aim: This study was conducted to assess the remineralizing ability, microleakage and flexural strength of resin-based and bioactive-based sealants in primary teeth.Methods: Thirty-two exfoliated second primary molars were prepared and sealed with one of the following materials: BeautiSealant and Helioseal F plus. Sixteen samples were subjected to a pH-cycling model (7 days of demineralization-remineralization cycles). Scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) were used to assess the remineralizing abilities before and after the studied sealants applied. The other (16) samples were subjected to a thermocycling model to assess the microleakage after sealants application. Flexural strength for each sealant material was also assessed following the ISO 4049 protocols using a Universal Testing Machine. Data were collected, tabulated then statistically analyzed using the Statistical Package of Social Science (SPSS) program Windows (Standard version 22).Results: After sealants application, the mean weight percentages of calcium (32.4,32.8), phosphate (15.7,16.6) and fluoride (13.6,14.02) showed a significant increase for Helioseal F and BeautiSealant respectively compared with baseline values. The mean Calcium/ Phosphate ratio (Ca/P) for Helioseal F plus was 2.163 and 1.796 for BeautiSealant after sealant application with no statistical significance difference was found. On the other hand, Helioseal F plus showed higher significance difference than BeautiSealant in flexural strength test. Conclusion:The bioactive giomer glass ionomer-based sealants could be used successfully as alternative to resin-based sealants as they showed comparable remineralizing ability and mechanical properties.
