摘要

本研究评估了用 35% 过氧化氢(HP)结合含 1% 四氟化钛(TiF4)的实验凝胶漂白的珐琅质的颜色变化、表面粗糙度、矿物质含量和形态。材料和方法用(n = 12)牛珐琅质块进行处理:(TiF)含 1% TiF4 的实验凝胶;(HP)35% HP;(HPT)35% HP + 1% TiF4;(CT)对照组。pH 值、比色参数、表面粗糙度、矿物质含量和釉质形态均已测定。pH 值的评估时间为 45 分钟。颜色参数在漂白前(T0)和最后一次漂白后 14 天(T4)测定。在漂白前(T0)和最后一次漂白后(T3)立即对表面粗糙度进行分析。在 T4 时对釉质矿物质含量和形态进行验证。结果STiF增加了表面粗糙度,HP和HPT在颜色和CO 3 2 - $$ {\mathrm{CO}}_3^{2-} 方面没有差异。PO 4 3 - $$ {\mathrm{PO}}_4^{3-}$$ 矿物含量。结论:TiF4 和 35% HP 的组合不会干扰珐琅质漂白效果、控制表面粗糙度并保持矿物质含量,但会促进轻微的表面形态改变。临床意义由于漂白的不良影响,四氟化钛(TiF4)因其治疗特性而备受关注,包括逆转矿物质流失和中和矿物质结构再矿化的能力。因此,TiF4 的再矿化能力可能是将其加入过氧化氢漂白剂中的一个很好的替代品。

Evaluation of Enamel Surface Properties Submitted to Bleaching With 35% Hydrogen Peroxide Associated With Titanium Tetrafluoride (TiF4).
OBJECTIVE This study evaluated the color change, surface roughness, mineral content and morphology of enamel bleached with 35% hydrogen peroxide (HP) combined with an experimental gel containing 1% titanium tetrafluoride (TiF4). MATERIALS AND METHODS Bovine enamel blocks were treated with (n = 12): (TiF) experimental gel containing 1% TiF4, (HP) 35% HP, (HPT) 35% HP + 1% TiF4 and (CT) control. Bleaching with HP was performed in 3 sessions (3 × 15 min/applications). pH, colorimetric parameters, surface roughness, mineral content and enamel morphology were determined. The pH was evaluated for 45 min. The color parameters were determined before bleaching (T0), and 14 days elapsed from the last bleaching session (T4). Surface roughness was analyzed at T0 and immediately after last bleaching session (T3). Enamel mineral content and morphology were verified at T4. Data were statistically analyzed by one-way, two-way ANOVA and Kruskal-Wallis (α = 0.05). RESULTS TiF increased surface roughness, and no differences between HP and HPT in terms of color and CO 3 2 - $$ {\mathrm{CO}}_3^{2-} $$ - PO 4 3 - $$ {\mathrm{PO}}_4^{3-} $$ mineral content. Ti was detected only on TiF, and slight surface morphology changes were observed in bleached enamel. CONCLUSIONS The combination of TiF4 and 35% HP did not interfere with the enamel bleaching effect, controlled surface roughness, and kept mineral content but promoted a minor surface morphology alteration. CLINICAL SIGNIFICANCE Due to the adverse effects of bleaching, titanium tetrafluoride (TiF4) has gained attention for its therapeutic properties, including the ability to reverse mineral loss and neutralize remineralization of mineral structures. Therefore, TiF4's remineralizing capacity may be a good alternative for incorporation into hydrogen peroxide bleaching agents.
