Abstract

Background and Objective: White spot lesions (WSLs) are commonly seen after completing orthodontic treatment. Different approaches have been suggested to avoid such a complication. Recently, 45S5 bioglass (BG) was introduced as remineralizing agent. Therefore, the objective of this in-vitro study was to assess the effect of BG in remineralizing WSLs using Optical coherence tomography (OCT). Methods: Fifteen human premolar teeth were sectioned and bonded to orthodontic brackets with Transbond XT primer followed by Transbond PLUS color change adhesive (3M Unitek, USA) on their smooth surfaces according to the manufacturer’s instructions. Then, all specimens were varnished excluding the area of interest (AOI) around the bonded restoration, immersed in demineralizing solution and imaged by cross-polarization OCT (CONT group), and the maximum pixel value (MPV) of the AOI were calculated. Then, they were subjected to remineralizing solutions and BG application followed by OCT imaging (REM group). Results: Mann-Whitney test showed the MPV of the AOI in REM was greatly increased and was significantly different from CONT (p<0.05). Conclusion: CP-OCT is a useful diagnostic tool that can be used to detect surface changes in enamel by MPV technique. The BG has a great potential to remineralize enamel defects, however further investigation is required.
