The present study was to evaluate pH values of apexification materials.
The materials were placed in 1 cm long and 4 mm diameter tubes. After sample immersion, glass flasks were hermetically sealed with rubber caps to attenuate any effects of external environmental factors and maintained at 37°C. The power hydrogen of the pastes was measured 1 hour, 3 hours, 8 hours, 24 hours, 72 hours and 7 days after preparation. pH was calibrated with solutions of known pH (7.0). Mann-Whitney test were used to determine significant differences.
The mean pH of all medications was < 12.0 throughout the experiment. At 24 hours, EndoCal 10 had the highest pH of all the materials (p < 0.05).
According to the results obtained, it may be concluded that calcium oxide (EndoCal 10) presented the highest pH compared with mineral trioxide aggregate (MTA) and Calasept Plus [Ca(OH)2].
Apexification is an important treatment in immature teeth. For this reason, used materials in apexification should have some properties, such as high pH and stimulating to be hard tissue. Therefore, the material should be chosen carefully in apexification of immature teeth.
本研究旨在评估根尖诱导成形术材料的pH值。
将材料置于长度为1厘米、直径为4毫米的试管中。样品浸泡后，用橡胶帽将玻璃瓶密封，以减弱外部环境因素的任何影响，并保持在37°C。在制备后1小时、3小时、8小时、24小时、72小时和7天测量糊剂的氢离子浓度。用已知pH值（7.0）的溶液校准pH值。采用曼-惠特尼检验确定显著差异。
在整个实验过程中，所有药物的平均pH值均<12.0。在24小时时，EndoCal 10在所有材料中pH值最高（p<0.05）。
根据所得结果，可以得出结论，与矿物三氧化物凝聚体（MTA）和Calasept Plus[氢氧化钙（Ca(OH)2）]相比，氧化钙（EndoCal 10）的pH值最高。
根尖诱导成形术是治疗年轻恒牙的重要方法。因此，根尖诱导成形术中使用的材料应具有一些特性，如高pH值和对硬组织有刺激性。因此，在年轻恒牙的根尖诱导成形术中应谨慎选择材料。
