根尖发育未完成的牙要进行常规的根管充填,必须先行根尖成形术。氢氧化钙具有刺激钙化组织形成,完成根尖闭合的能力,因而目前仍是根尖成形术中常用的材料。本研究的目的是评价氢氧化钙治疗的作用及根尖孔直径对根尖硬组织形成的时间和硬组织类型的影响。
Apical development of unfinished teeth To perform conventional root canal filling, apical apical surgery must be performed first. Calcium hydroxide has the ability to stimulate the formation of calcified tissue to complete apical closure, which is still the most common apodysis material. The purpose of this study was to evaluate the effect of calcium hydroxide treatment and the effect of apical foramen diameter on the time and hard tissue type of apical hard tissue formation.
