Comparative Evaluation of Remineralization Potential of Commercially Available Remineralization Agents - An In-Vitro Micro-Hardness Study.

Introduction: Dental erosion has become a common etiology for dentinal hypersensitivity with increase in the amount of cola drinks in the recent years. This in-vitro study was aimed to compare and evaluate remineralization potential of commercially available remineralization agents GC Tooth Mousse, Toothmin, Aclaim and Conybio plus after immersion in cola solution using Vickers micro hardness test. Materials and Methods : Twenty-five extracted human premolars tooth were taken for the study. Each tooth was split into four enamel blocks of dimensions (3mm long, 3mm width and 2mm thick) and embedded in acrylic blocks of size 5 x 5 x 5 mm. Each specimen was then immersed in carbonated drink with pH 2.7 for 8 min and washed with deionized water after every 2 min simulating in vivo soft drink consumption for one week. After the erosion process was completed, all the specimens were rinsed in deionized water and blotted dry . Fresh remineralizing paste was applied to the treatment halves for 3 minutes at 0, 8, 24, 36 and 48 hours.  Vickers microhardness measurements was performed at 24- and 48-hour post treatment. Conclusion: Toothmin claims to produce better remineralization compared to other commercially available toothpaste. Key words: GC Tooth Mousse, Toothmin, Aclaim and Conybio plus
