【摘要】：目的：觀察Vitapex糊劑、氫氧化鈣糊劑治療慢性根尖周炎的臨床療效。方法：選擇有明顯慢性根尖周炎患者100例，分為A、B兩組，每組50例。A組50例采用Vitapex糊劑治療慢性根尖周炎，B組50例采用氫氧化鈣糊劑治療慢性根尖周炎。對(duì)比Vitapex糊劑與氫氧化鈣糊劑治療慢性根尖周炎的臨床療效。 結(jié)果：1.Vitapex糊劑比氫氧化鈣糊劑治療慢性根尖周炎的臨床療效顯著。2. Vitapex對(duì)根尖周組織不產(chǎn)生刺激，體積不會(huì)收縮，凝固后與根管壁不會(huì)產(chǎn)生間隙，X線阻射，操作上簡(jiǎn)單易行，不會(huì)使牙齒發(fā)生變色等優(yōu)點(diǎn)。3.氫氧化鈣糊劑的弊端（1）粘稠度及流動(dòng)性差，，氫氧化鈣必須與根尖組織密切接觸才能充分發(fā)揮作用；（2）易吸收，若尖周炎癥未能控制，吸收后炎性結(jié)締組織進(jìn)入根管，反而影響正常的根尖修復(fù)；（3）對(duì)Ｘ線不阻射，故不易掌握其充填深度，對(duì)準(zhǔn)確判斷根管充填情況及療效分析帶來一定困難；（4）需臨時(shí)配制從而增加了操作工序,而且對(duì)彎曲的小根管充填困難，形成的鈣化橋有時(shí)不在根尖1/3處，而在根中1/3處。 結(jié)論：Vitapex糊劑治療慢性根尖周炎效果更好，可在臨床推廣使用。
[Abstract]:Objective: to observe the clinical effect of Vitapex paste and calcium hydroxide paste on chronic periapical periodontitis. Methods: one hundred patients with chronic periapical periodontitis were divided into two groups: group A (n = 50) and group A (n = 50) treated with Vitapex paste. Group B (n = 50) was treated with calcium hydroxide paste for chronic periapical periodontitis. To compare the clinical efficacy of Vitapex paste and calcium hydroxide paste in the treatment of chronic periapical periodontitis. Results 1. Vitapex paste was more effective than calcium hydroxide paste in the treatment of chronic periapical periodontitis. Vitapex has no stimulation on periapical tissue, no contraction in volume, no gap between Vitapex and root canal wall after solidification, simple operation and no discoloration of teeth. The disadvantages of calcium hydroxide paste (1) poor viscosity and fluidity, calcium hydroxide must be in close contact with the root tip tissue to play a full role, (2) easy to absorb, if the periapical inflammation can not be controlled, the absorption of inflammatory connective tissue into the root canal, On the contrary, it affects the normal apical restoration; (3) it is difficult to grasp the depth of the root canal filling because it does not block the radiography, so it is difficult to accurately judge the root canal filling condition and the curative effect analysis; (4) the temporary preparation is needed to increase the operation procedure. It is also difficult to fill curved small root canals, and calcified bridges are sometimes formed not at a third of the root tip, but at a third of the root. Conclusion Vitapex paste is more effective in the treatment of chronic apical periodontitis and can be popularized in clinic.
