“…Several in vitro studies demonstrated that the application of BAG either before, after or during teeth bleaching did not negatively affect the bleaching efficacy. Moreover, this association exhibited many benefits including, reduced mineral degradation [ 47 , 48 ], reduced losing of enamel microhardness [ 49 , 50 ], conserved enamel surface integrity [ 50 , 51 ] and minimized the infiltration of peroxides into pulp chambers [ 52 ].…”

Background The aim of this study was to evaluate the effect of bioactive glass (BAG) 45S5 paste on colour change and tooth sensitivity (TS) when used in combination with 20% carbamide peroxide (CP) during at-home vital tooth bleaching. Methods Twenty-four patients were selected and assigned into two experimental groups (n = 12) in a double-blind study design. Each patient received 20% CP followed by the application of either BAG paste or non-active placebo paste. The shade evaluation was performed using a digital spectrophotometer based on the CIE L*a*b* colour space system at different time points and the overall colour changes ΔE were calculated. TS was evaluated using visual analogue scale (VAS). The values of ΔE and TS were statistically analysed using paired t-test. The level of statistical significance was established at p = 0.05. Results The overall colour changes (ΔE) between baseline and each time point showed no significant differences between BAG and placebo groups (p > 0.05). The use of BAG paste significantly decreased TS reported by the participants. Conclusions The association of BAG paste with at-home bleaching treatment presents a promising method as it decreased TS and did not deteriorate bleaching efficacy. Trial registration This study was approved and registered in the Australian New Zealand Clinical Trials Registry (ANZCTR) under Registration number: ACTRN12621001334897.

Aim: The purpose of this study was to evaluate of the effects of modified 45S5 bioglass (BG) before, after, and during the bleaching procedure with 35% hydrogen peroxide (HP) on the tooth colour change and physicochemical and morphological properties of human enamel. Methods: Forty-two human premolar enamel samples were prepared and randomly divided into six groups as G1: control (deionized distilled water for 20 min), G2: BG (Bioglass suspension for 20 min), G3: HP (hydrogen peroxide 35% for 20 min), G4: BG before HP (Bioglass suspension for 20 min followed by hydrogen peroxide 35%) , G5: BG after HP (hydrogen peroxide 35% followed by Bioglass suspension for 20 min), and G6: BG during HP (Bioglass in hydrogen peroxide 35% suspension for 20 min). The treatment procedure was performed on the whole enamel surface. Colorimetry was done before and after the treatment procedure. Two specimens from each group were selected for morphological analysis with scanning electron microscope (SEM). Microhardness analysis was performed after the treatment procedure and chemical analysis of BG dissolution was done for BG+DDW and BG+HP suspensions. Results: No statistically significant difference in colour was observed among different groups (P= 0.073133) and the yellowness index decreased in all of the four HP groups. The greatest reduction in microhardness occurred in groups HP and BG before HP (P<0.001) while the BG group showed increased microhardness measurements (P<0.001). Statically significant differences in microhardness were found among the groups. Elemental analysis showed significantly increased levels of Ca and P in BG after HP and BG before HP groups when compared to the HP group. Ionic release of BG was significantly greater in HP when compared to DDW. Conclusion: Using BG before HP had a greater protective effect since it increased microhardness more effectively, decreased mineral loss, and retained the integrity of the enamel surface. The HP group had the lowest microhardness and BG during HP showed less protective effects compared to BG before HP.
