Effect of Preventive Dental Products on Bonding Force: An Study.

Aim: Testing the effect of Fluoride, chlorhexidine, and molecular iodine applications on the mean micro-shear bond strength (SBS) of enamel in an attempt to preserve enamel integrity during the bonding process.

Materials And Methods: The study was an observational case-control one in which 150 human teeth were classified into 10 groups according to the product kind and the prescribed treatment. Each group consisted of 15 teeth. Group C was the control group. Groups FP, FV, and OS utilized products that could be utilized in a professional dental setting. Group FP was treated with 1.23% NaF prophy paste, Group FV was treated with 5% NaF varnish, and Group OS was treated with Opal® Seal Fluoride releasing primer and sealant. Groups L, LF, CHX, and I were treated with mouth rinses. Group L was treated with Listerine Zero Fluoride-Free Mouthwash, Group LF with Listerine Zero 0.02% NaF Mouth Rinse, Group CHX with 0.12% chlorhexidine gluconate, and Group I with ioRinse RTU 100 ppm molecular iodine rinse. Groups TP and G utilized alternative remineralization products. Group TP was treated with Fluoro Calcium Phosphosilicate bioglass containing toothpaste, and Group G was treated with Curodont Protect remineralizing tooth gel. One-way ANOVA test was utilized to perform all statistical analysis in this study.

Results: For mean micro-SBS, no significant difference ( > 0.05) between any of the experimental groups was observed when compared to the control group. There was a significant difference ( < 0.05) between Opal Seal versus Listerine Total, Opal Seal versus Peridex, Listerine versus Listerine Total, and Listerine versus Peridex. All other experimental group comparisons revealed a nonsignificant difference ( > 0.05).

Conclusions: As the null hypothesis (H0) assumes that changes observed in an experiment are due to chance, hence, the outcomes of this study are coherent with (H0) since the aforementioned application methods did not significantly impact the SBS of orthodontic resin cement to enamel.
