The aim of this study was to compare the aging effects on wear, surface roughness and microhardness of fissure sealants having varying contents. Four fissure sealant types were used in the study: Aegis (Bosworth, USA) (Group A), Beautisealant (Shofu, Japan) (Group B), Clinpro (3M, USA) (Group C), and Ultraseal XT/Hydro (Ultradent, USA) (Group U). Hundred disc-shaped specimens (5 mm diameter/3 mm width) were designed according to the manufacturer's instructions and assigned for microhardness/Vickers Hardness (VHN), surface roughness, and wear tests. Thermocycling (10,000 times/5-55 • C ± 2 • C/20 s) and chewing simulator (75,000 times/49 N) were applied as the aging procedures. Measurements were made before and after the aging procedures. The specimens were examined by Scanning Electrone Microscopy (SEM). Data was statistically analyzed through Kruskal Wallis, Wilcoxon and Welch tests. The highest and the lowest changes in mean microhardness values were obtained for Group U (9.88 ± 1.46) and Group A (4.40 ± 0.46), respectively; and a significant difference (p < 0.001) was found between the mean changes in microhardness numbers (U > B > C > A). The median roughness values had no significant difference; the surface roughness had the highest mean differences in Groups U and C (U = C > A > B). Significant difference was found between the mean changes in wear/weight values (p < 0.001); the highest and the lowest mean weight losses were recorded in Group U (0.0097 ± 0.0003 gr), and Group C (0.0041 ± 0.0006 gr), respectively (U > B > A > C). The highest physical changes were determined in Group U after the aging procedures. It is concluded that the aging procedures affect physical structures of all test materials with varying degrees, however Ultraseal XT/Hydro is the most affected. The individual treatment needs and material properties must be considered to select a fissure sealant material.

“…(29) The use of sealants undoubtedly contributes to reducing the incidence of dental caries, there is a new revolutionary set of sealants that are releasing fluoride cross the whole world. (30,31) Unique bioactive rechargeable sealants include unique capabilities, including the ability to release and recharge fluoride in the mouth. (32) The present study was conducted to compare between a novel bioactive giomer material (Beautisealant) and unique Bis-GMA-free sealant material ( Helioseal F Plus) in primary teeth.…”

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.

“…The sealants and mouth rinses are mostly bactericidal and bacteriostatic against Streptococcus mutans, the most common bacteria that initiate dental caries [8]. The main disadvantages reported are changes in taste sensation, tooth stains, burning sensation, incomplete photopolymerization, microleakage, and bond strength [9]. The herbal concoctions are thought to be moderately effective and less harmful than the majority of commercially available pharmaceutical mouthwashes [10].…”

Introduction: Dental caries has become a substantial global health burden, and many techniques have been used in dentistry to protect the tooth from decay. Brassica oleracea is a green cruciferous vegetable with a good source of vitamins C, K and E, which are also effective antibiotics and antioxidants. These characteristics will shield the oral cavity from pathogenic onslaught and can be considered during the formulation of antimicrobial mouthwash, toothpaste, or dental sealants.Materials and methods: B. oleracea extract was prepared by heating and condensing the red and green cabbage. Both extracts were assessed for antimicrobial activity (antibacterial and antifungal activities) and cytotoxicity. After incubation, the zone of inhibition was calculated for antibacterial activity and the number of live nauplii for cytotoxicity.Results: The extract from red cabbage was found to have more effective antibacterial properties than that from green cabbage. The red B. oleracea extract formed the highest zone of inhibition against Candida albicans (20 mm), followed by Enterococcus faecalis (15 mm) and Streptococcus mutans (9 mm). In contrast, the green cabbage extract formed the highest inhibition against E. faecalis (12 mm). The cytotoxicity increases with increased concentration, with the highest toxicity at 20 µL for both extracts. Conclusion:The properties of B. oleracea can be utilized in dental products such as toothpaste, mouthwash, and dental sealants due to their antibacterial effects. By incorporating B. oleracea extracts into these products, oral health professionals may soon have additional tools to promote oral hygiene and prevent oral infections, offering a natural and effective alternative to traditional oral care ingredients.
