Power Hydrogen Evaluation of Apexification Materials: EndoCal 10, Mineral Trioxide Aggregate and Calasept Plus.
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.
