顯微根尖手術(shù)聯(lián)合MTA治療難治性慢性根尖周炎的研究
[Abstract]:Objective: to study the feasibility, characteristics, success rate and related influencing factors of MTA in the treatment of refractory chronic periapical periodontitis. Methods: the clinical data of 146 refractory chronic periapical periodontitis teeth were analyzed from January 2013 to December 2015 in 106 patients with refractory chronic periapical periodontitis, including 75 cases of maxillary anterior teeth and 13 cases of mandibular anterior teeth. There were 6 cases of maxillary premolars, 4 cases of mandibular premolars, 4 cases of maxillary molars and 4 cases of mandibular molars. The operation included apical resection, apical inversion preparation and apical filling. 1 year after operation, the curative effect was evaluated by clinical symptoms and radiology, and the prognostic factors were analyzed by chi-square test. Results: the 1-year success rate of microapical surgery combined with MTA was 95.9% (140 脳 146). According to the sex, age, tooth position and the range of apical lesions, there was no significant difference between the two groups. 5 cases (6 teeth) failed, the main causes were root fracture and severe periodontitis. Conclusion: microapical surgery combined with MTA can achieve satisfactory results in the treatment of refractory chronic periapical periodontitis, and microapical surgery is an effective method for the treatment of chronic periapical periodontitis.
