Comprehensive Evaluation of Effect of Remineralizing Agents on Bond Strength in Between Two Commercially Available Restorative Composite Resins and Enamel in Deciduous Teeth: An Original Research Study

Abstract

Background and Aim: Tooth remineralization is a reparative procedure, which happens naturally and daily in the oral cavity. This remineralization procedure repairs the vanished enamel and helps in preventing dental caries. Commercially available remineralizing agents also used for these purposes. However, they have been shown to affect the bond strength of composite resins. This study was designed to comprehensively evaluate the effect of remineralizing agents on bond strength in between two commercially available restorative (composite) resins and enamel in deciduous teeth.  

Materials & Methods: This study was performed in the department of Pedodontics and Preventive dentistry which included forty deciduous maxillary molars. Two commercially available restorative composite resins were used on the buccal surface of enamel. Group one included twenty samples in which Beautifil Flow Plus X was used. Group two included twenty samples in which Filtek™ Z350 XT Universal Restorative was used. All samples were immersed in to Remineralization agent independently. Universal testing machine was used to evaluate the shear bond strength between composite resins and enamel. Readings were noted before and after immersion into Remineralization agent. P value less than 0.05 was considered significant (p< 0.05).

Statistical Analysis and Results: Statistical analysis was done by statistical software Statistical Package for the Social Sciences (SPSS). The resultant data was sent to suitable statistical tests to achieve p values, mean, standard deviation, standard error an 95% CI. P ≤ 0.05 was considered as statistically significant. Out of 40 studied patients, males were 25 and females were 15. All studied patients were separated into four age groups. After immersion into Remineralization agent, highest mean (shear bond strength) was noticed for group 1 samples (15.08). After immersion into Remineralization agent, minimum mean (shear bond strength) was noticed for group 2 samples (12.52).

Conclusion: Within the limitations of the study, authors concluded that the tested remineralizing agent literally affects shear bond strength in between studied composite resins and enamel of primary teeth.
