Recently, the development of dental materials has increased the availability of various hyperesthesia desensitizers. However, there are no studies on the duration of retreatment in terms of adherence rates. Thus, the adhesion rates of resin-based desensitizers were investigated. We used a conventional desensitizer and a recently developed desensitizer containing calcium salt of 4-methacryloxyethyl trimellitic acid (C-MET) and 10-methacryloyloxydecyl dihydrogen calcium phosphate (MDCP). These colored agents were applied to the surfaces of premolars and molars, and the area was measured from weekly oral photographs. Areas were statistically analyzed and mean values were calculated using 95% confidence intervals. A p-value of <0.05 was considered statistically significant. These rates were significantly higher on the buccal side of the maxilla and lower on the lingual side of the maxilla. In addition, the desensitizer containing C-MET and MDCP displayed significantly higher adhesion rates. It is suggested that this will require monthly follow-ups and reevaluation because both agents cause less than 10% adherence and there is almost no sealing effect after 4 weeks. In addition, the significantly higher adhesion rate of the desensitizer containing C-MET and MDCP indicated that the novel monomer contributed to the improvement in the adhesion ability.
最近，牙科材料的发展增加了各种过敏症脱敏剂的可用性。然而，关于再治疗持续时间的依从率尚无研究。因此，对树脂基脱敏剂的粘附率进行了研究。我们使用了一种传统的脱敏剂和一种最近开发的含有偏苯三酸4-甲基丙烯酰氧基乙酯钙盐（C-MET）和10-甲基丙烯酰氧基癸基磷酸二氢钙（MDCP）的脱敏剂。将这些显色剂应用于前磨牙和磨牙的表面，并从每周的口腔照片中测量面积。对面积进行统计学分析，并使用95%置信区间计算平均值。p值<0.05被认为具有统计学意义。这些比率在上颌颊侧显著更高，在上颌舌侧显著更低。此外，含有C-MET和MDCP的脱敏剂显示出显著更高的粘附率。由于两种试剂的粘附率均低于10%，且4周后几乎没有密封效果，因此建议每月进行随访和重新评估。此外，含有C-MET和MDCP的脱敏剂显著更高的粘附率表明，这种新型单体有助于提高粘附能力。
