Abstract

Effectiveness of Two Bioactive Restorative Materials in Dental Hard Tissues Remineralization as Indicated by Laser Fluorescence

Author(s):Turki Hasan Alotibi and Yasser Maher El-Bouhi

Twenty extracted human sound premolars were selected and grouped into four groups and two class V cavity preparations, facial and lingual, were prepared at the cervical one-third of the crown of each tooth and extending into the root cementum to make a total of 40 cavities (n=10). The teeth were soaked in a demineralizing solution of pH 4.5 for 72 hours and a tooth surface conditioner was applied to remove remnants of the smear layer. Three laser fluorescence readings were recorded by DIAGNOdent pen for each cavity at enamel margin, dentin floor, and cementum margin. The groups were restored with four different restorative materials Cavit, temporary filling material (control), Ketac-Fil; a conventional glass-ionomer, and two bioactive restorative materials; Glass Carbomer and Biodentine. The restored teeth were stored in mineral water (37°C) for three weeks and brushed twice daily with Tooth Mousse toothpaste. The teeth were longitudinally cut into halves in the middle of the restorations and three DIAGNOdent pen readings were recorded at the same previous sites. Data were collected and statistically analyzed by one-way ANOVA and Tukey’s post-hoc-test at (p??0.05). The results showed a significant increase in DIAGNOdent pen readings after soaking in the demineralizing solution in all tooth hard tissues, while a significant decrease was noted after the application of the restorations and storage in the three groups, other than control, indicating that both examined bioactive restorative materials were suitable for enhancing remineralization and subsequently arresting the three-tooth hard tissues carious lesions as the conventional glass-ionomer.
