Aim: The aim of this study was to comparatively evaluate the effect of 4% titanium tetrafluoride (TiF4) and 1.23% acidic phosphate fluoride (APF) gel on the microhardness of human coronal dentin. Materials and Methods: Thirty noncarious extracted premolars were collected and sectioned buccolingually with the help of diamond disk. Exposing the sectioned surface, teeth were embedded in self-cure acrylic. Exposed coronal dentin was polished with abrasive papers starting with 220–5000 grit. Microhardness was evaluated by Vickers microhardness evaluator, at four different stages as follows - stage 1: Baseline values, Stage 2: Exposure of specimens to acidic environment at a pH 1 for 5 min, Stage 3: Application of 1.23% APF gel and 4% TiF4 (after dividing the specimens into two groups, i.e., Group A and B, respectively), and Stage 4: Followed by exposure of fluoridated specimens to acidic protocol as mentioned above. Results: Paired t-test was used to compare the readings between Groups A and B. Group B has shown greater resistance to decrease in microhardness of coronal dentin (P < 0.05) on exposure to acidic protocol. Conclusion: Due to acidic pH (1.5) of 4% TiF4, amount of increase in microhardness of dentin is <1.23% APF gel. 4% TiF4 was more effective in resisting demineralization than 1.23% APF gel.
