    Abstract:
    OBJECTIVE: The purpose of this study was to investigate the effects of aqueous solutions of different concentrations of titanium tetrafluoride (TiF4) on dentin matrix stability up to six months. DESIGN: Dentin specimens prepared from fifteen nonerupted molars were demineralized and randomly distributed into groups: 2.5% TiF4, 4% TiF4, 1000 ppm NaF, and control (distilled water). The modulus of elasticity (ME) and dry masses of the dentin matrix were determined at baseline, and up to 6 months following treatment. Collagen solubilization was estimated by hydroxyproline (HYP) quantification in the simulated body fluid used to store the dentin specimens. RESULTS: The 2.5% TiF4 group presented higher ME immediately after treatment, and at 3 and 6 months storage, whereas 4% TiF4 showed higher means at 3 and 6 months (p < 0.001). No significant differences were observed among the groups over time (p = 0.9325). However, the 2.5% TiF4 group showed significantly higher ME than the control group, immediately after treatment. All the groups presented significantly higher mass change immediately, compared with 3 and 6 months (p < 0.0001). Except for the 4% TiF4 group, HYP release was higher in the first quarter (p = 0.0152), when no significant differences were found among the groups. In the second quarter, the means were significantly higher in the 2.5% TiF4 and 4% TiF4 groups. The group treated with 2.5% TiF4 had a statistically higher HYP release than the control group. CONCLUSION: An aqueous solution of 2.5% TiF4 increases the immediate stiffness values, but does not stabilize the collagenous dentin matrix.
