OBJECTIVE This in situ study evaluated the effect of high-fluoride dentifrice (5000 μg F-/g) and fluoride-containing bonding composite resin on enamel demineralization adjacent to orthodontic brackets. METHODS Ten volunteers wore palatal appliances containing bovine enamel blocks with metallic brackets bonded with fluoride-free or fluoride-containing composite resin. During three phases of 14 days each, three dentifrices with different fluoride concentrations (0, 1100, and 5000 μg F-/g) were tested. The cariogenic challenge consisted of 20% sucrose solution dripped 8x/day onto the dental blocks. At the end of each phase, biofilm formed was collected for fluoride analysis. Cross section hardness was performed in enamel blocks, and the lesion area was calculated. Data were analyzed by two-way ANOVA followed by Tukey post hoc test (α = 5%). RESULTS The only signicant factor for all the variables under study was the dentifrice. Smaller lesion area and higher fluoride concentration on biofilm were found in 5000 μg F-/g group, irrespective of bonding composite resin (p < 0.001). Neither bracket-bonding composite resin nor the interaction between the factors was statistically significant (p > 0.05) for all the variables. CONCLUSION High-fluoride dentifrice is effective in reducing demineralization on enamel adjacent to orthodontic brackets, while the fluoride-containing bonding composite resin does not influence it. CLINICAL SIGNIFICANCE Since high-fluoride dentifrice was able to reduce demineralization adjacent to brackets, it can be an option to caries management in orthodontics patients.

高氟洁牙剂和托槽粘结复合材料对牙釉质原位矿化的影响。

目的这项原位研究评估了高氟化物洁牙剂(5000μgF- / g)和含氟粘结复合树脂对正畸托槽附近牙釉质脱矿的影响。方法十名志愿者穿着pa器械,其中装有带有搪瓷支架的牛牙釉质块,并用无氟或含氟复合树脂粘合。在每个阶段为14天的三个阶段中,测试了三种具有不同氟化物浓度(0、1100和5000μgF- / g)的洁牙剂。致龋的挑战包括每天以8x /天滴到牙膏上的20%蔗糖溶液。在每个阶段结束时,收集形成的生物膜用于氟化物分析。在搪瓷块中进行截面硬度,并计算病变面积。数据通过双向方差分析进行分析,然后进行Tukey事后检验(α= 5%)。结果所研究的所有变量的唯一重要因素是洁齿剂。5000μgF- / g组的病灶面积较小,生物膜上的氟化物浓度较高,而与粘结复合树脂无关(p <0.001)。对于所有变量,方括号键合复合树脂和因素之间的相互作用均无统计学意义(p> 0.05)。结论高氟化物洁牙剂可有效减少正畸托槽附近牙釉质的脱矿质作用,而含氟的粘结复合树脂则不会对其产生影响。临床意义由于高氟洁牙剂能够减少托槽附近的脱矿物质,因此它可以作为正畸患者龋齿治疗的一种选择。5000μgF- / g组的病灶面积较小,生物膜上的氟化物浓度较高,而与粘结复合树脂无关(p <0.001)。对于所有变量,方括号键合复合树脂和因素之间的相互作用均无统计学意义(p> 0.05)。结论高氟化物洁牙剂可有效减少正畸托槽附近牙釉质的脱矿质作用,而含氟的粘结复合树脂则不会对其产生影响。临床意义由于高氟洁牙剂能够减少托槽附近的脱矿物质,因此它可以作为正畸患者龋齿治疗的一种选择。5000μgF- / g组的病灶面积较小,生物膜上的氟化物浓度较高,而与粘结复合树脂无关(p <0.001)。对于所有变量,方括号键合复合树脂和因素之间的相互作用均无统计学意义(p> 0.05)。结论高氟化物洁牙剂可有效减少正畸托槽附近牙釉质的脱矿质作用,而含氟的粘结复合树脂则不会对其产生影响。临床意义由于高氟洁牙剂能够减少托槽附近的脱矿物质,因此它可以作为正畸患者龋齿治疗的一种选择。对于所有变量,方括号键合复合树脂和因素之间的相互作用均无统计学意义(p> 0.05)。结论高氟化物洁牙剂可有效减少正畸托槽附近牙釉质的脱矿质作用,而含氟的粘结复合树脂则不会对其产生影响。临床意义由于高氟洁牙剂能够减少托槽附近的脱矿物质,因此它可以作为正畸患者龋齿治疗的一种选择。对于所有变量,方括号键合复合树脂和因素之间的相互作用均无统计学意义(p> 0.05)。结论高氟化物洁牙剂可有效减少正畸托槽附近牙釉质的脱矿质作用,而含氟粘结复合树脂则不会对其产生影响。临床意义由于高氟洁牙剂能够减少托槽附近的脱矿物质,因此它可以作为正畸患者龋齿治疗的一种选择。
