The present study was conducted to evaluate the effect of different topical agents utilized for prevention of enamel decalcification around orthodontic brackets bonded to bleached and non-bleached enamel.
Human maxillary premolars (n = 120) were divided into two equal groups. Teeth in group I were left without bleaching while those in group II were bleached with Vivastyle gel. Metal brackets were bonded to all the teeth using light-cured adhesive. Each group was divided into six equal subgroups (A, B, C, D, E, and F). In subgroup A, no material was applied (control). In subgroups B, C, D, E, and F, the following materials were applied respectively: Profluorid varnish, Enamel Pro Varnish, Ortho-Choice Ortho-Coat, GC Tooth Mousse, and GC MI Paste Plus. All teeth were cycled in a demineralization solution/artificial saliva for 15 days. Laser fluorescence was used to measure the level of enamel mineralization. The data were statistically analyzed.
Regarding the non-bleaching subgroups, all studied material revealed significant demineralization reduction in comparison to the control subgroup (P < 0.05). Ortho-Choice Ortho-Coat revealed the highest significant effect while GC Tooth Mousse showed the least effect. In bleached subgroups, Profluorid varnish, Enamel Pro Varnish, and Ortho-Choice Ortho-Coat significantly reduced demineralization (P < 0.05) while either GC MI Paste Plus or GC Tooth Mousse had no significant effects (P > 0.05).
Ortho-Choice Ortho-Coat, and Profluorid and Enamel Pro varnishes could be utilized successfully to reduce enamel demineralization around brackets bonded to either bleached or non-bleached enamel. GC MI Paste Plus and GC Tooth Mousse were effective only in non-bleached enamel.
本研究旨在评估不同的局部制剂用于预防正畸托槽粘接于漂白和未漂白牙釉质周围脱矿的效果。
将 120 个人上颌前磨牙分为两组。组 I 牙齿未经漂白，组 II 牙齿用 Vivastyle 凝胶漂白。所有牙齿均用光固化粘结剂粘结金属托槽。每组再分为 6 个亚组（A、B、C、D、E 和 F）。亚组 A 不使用任何材料（对照）。亚组 B、C、D、E 和 F 分别使用 Profluorid 漆、Enamel Pro 漆、Ortho-Choice Ortho-Coat、GC Tooth Mousse 和 GC MI Paste Plus。所有牙齿均在脱矿溶液/人工唾液中循环 15 天。用激光荧光仪测量牙釉质矿化水平。对数据进行统计学分析。
对于非漂白亚组，与对照组相比，所有研究材料均显著减少脱矿（P<0.05）。Ortho-Choice Ortho-Coat 效果最显著，GC Tooth Mousse 效果最小。在漂白亚组中，Profluorid 漆、Enamel Pro 漆和 Ortho-Choice Ortho-Coat 显著减少脱矿（P<0.05），而 GC MI Paste Plus 或 GC Tooth Mousse 无显著效果（P>0.05）。
Ortho-Choice Ortho-Coat、Profluorid 和 Enamel Pro 漆可成功用于减少粘接于漂白或未漂白牙釉质的托槽周围的牙釉质脱矿。GC MI Paste Plus 和 GC Tooth Mousse 仅在未漂白牙釉质中有效。
