This study investigated the use of alendronate in the formation of new dentin in vitro. Extracted human premolar and molar teeth with immature apices were grown in tissue culture medium for 60 days. Six control specimens were grown without alendronate in the medium, and 22 experimental specimens were grown with alendronate at [10(-9) M] in the medium. Newly formed dentin was stained with tetracycline and procion brilliant red at days 1 to 3, 30 to 33, and 60. Specimens were decalcified and 5-micron sections were prepared for examination using fluorescent microscopy. New dentin formation was measured in microns at the most apical region, at 125-micron from the apical measurement and at 250-micron from the apical measurement. The alendronate group had 57.15% more growth than the control group at the most apical region, and this difference was significant (p = 0.0001). The results indicate that alendronate at [10(-9) M] is effective in accelerating dentin formation in vitro.
