Orthodontic treatment can be effective only with the proper adhesion strength of the bonded elements on the teeth. The aim of the study was to analyze the influence of different remineralization products on the brackets (Evolve Low Profile Brackets 0.022 Roth prescription (DB Orthodontics Ltd., Silsden, England) shear bond strength (SBS)). In all, 40 teeth were investigated for this study; n = 30 demineralized (immersed in 0.1% citric acid for 30 min, twice a day, for 20 consecutive days) and n = 10 immersed only in artificial saliva. After the demineralization process, remineralization agents were applied to each group (n = 10): Group I: Elmex Sensitive professional toothpaste (CP, Gaba GmbH, Witten, Germany) and GC MI Paste Plus (GC, Leuven, Belgium), Group II: Elmex Sensitive professional toothpaste (CP, Gaba GmbH, Germany) and GC Tooth Mousse (Leuven, Belgium), Group III: Elmex Sensitive professional toothpaste (CP, Gaba GmbH, Germany). For the teeth in control group C, Elmex Sensitive professional toothpaste was used. SBS tests were performed by means of an advanced materials-testing machine that generated maximum load and tensile strength values. The data obtained underwent statistical analysis (ANOVA and Tuckey test) with a statistical threshold of < 0.05. The SBS values were higher for group II (14.20 MPa) and I (10.36 MPa) and lower for group III (4.25 MPa) and C (4.11 MPa), with statistically significant differences between groups I and II when compared with groups III and C ( < 0.05). In conclusion, GC Tooth Mousse and MI-Paste Plus have no adverse effect on brackets SBS and are recommended to be used for enamel remineralization during orthodontic treatment.
正畸治疗只有在牙齿上粘结元件具有适当的粘结强度时才会有效。本研究的目的是分析不同再矿化产品对托槽（Evolve低轮廓托槽0.022 Roth规格，DB正畸有限公司，英国锡兹登）剪切粘结强度（SBS）的影响。本研究共调查了40颗牙齿；n = 30颗脱矿牙齿（每天两次浸泡在0.1%柠檬酸中30分钟，连续20天），n = 10颗仅浸泡在人工唾液中。脱矿过程后，将再矿化剂应用于每组（n = 10）：第一组：Elmex Sensitive专业牙膏（CP，加巴有限公司，德国维滕）和GC MI Paste Plus（GC，比利时鲁汶），第二组：Elmex Sensitive专业牙膏（CP，加巴有限公司，德国）和GC Tooth Mousse（比利时鲁汶），第三组：Elmex Sensitive专业牙膏（CP，加巴有限公司，德国）。对于对照组C中的牙齿，使用Elmex Sensitive专业牙膏。通过一台先进的材料测试机进行SBS测试，该测试机可生成最大载荷和拉伸强度值。所获得的数据采用统计阈值<0.05进行统计分析（方差分析和Tuckey检验）。第二组（14.20 MPa）和第一组（10.36 MPa）的SBS值较高，第三组（4.25 MPa）和C组（4.11 MPa）的SBS值较低，与第三组和C组相比，第一组和第二组之间存在统计学显著差异（<0.05）。总之，GC Tooth Mousse和MI-Paste Plus对托槽SBS没有不良影响，建议在正畸治疗期间用于牙釉质再矿化。
