In this study, we compared outcomes of traditional apicoectomy versus modern apicoectomy, by means of a controlled clinical trial with a 5-year follow-up. The study investigated 938 teeth in 843 patients. On the basis of the procedure performed, the teeth were grouped in 3 groups. Differences between the groups were the method of osteotomy (type of instruments used), type of preparation of retrograde cavity (different apicoectomy angles and instruments used for root-end preparation), and root-end filling material used (gray mineral trioxide aggregate or silver amalgam). Outcome (tooth healing) was estimated after 1 and 5 years, postoperatively. Clinical success rates after 1 year were 67% (306 teeth), 90% (186 teeth), and 94% (256 teeth) according to traditional apicoectomy (group 1), modern microsurgical apicoectomy using burns for osteotomy (group 2) or using piezo-osteotomy (group 3), respectively. After 1 year, group comparison results were statistically significant (P G 0.0001). Linear trend test was also statistically significant (P G 0.0001), pointing out larger healing from group 1 to group 3. After 5 years, teeth were classified into 2 groups on the basis of root-end filling material used. Clinical success was 90.8% (197 teeth) in the silver amalgam group versus 96% (309 teeth) in the mineral trioxide aggregate group (P G 0.00214). Multiple logistic regression analysis found that surgical technique was independently associated to tooth healing. In conclusion, modern apicoectomy resulted in a probability of success more than 5 times higher (odds ratio, 5.20 [95% confidence interval, 3.94Y6.92]; P G 0.001) compared with the traditional technique.

Abstract

In this study, we compared outcomes of traditional apicoectomy versus modern apicoectomy, by means of a controlled clinical trial with a 5-year follow-up. The study investigated 938 teeth in 843 patients. On the basis of the procedure performed, the teeth were grouped in 3 groups. Differences between the groups were the method of osteotomy (type of instruments used), type of preparation of retrograde cavity (different apicoectomy angles and instruments used for root-end preparation), and root-end filling material used (gray mineral trioxide aggregate or silver amalgam). Outcome (tooth healing) was estimated after 1 and 5 years, postoperatively. Clinical success rates after 1 year were 67% (306 teeth), 90% (186 teeth), and 94% (256 teeth) according to traditional apicoectomy (group 1), modern microsurgical apicoectomy using burns for osteotomy (group 2) or using piezo-osteotomy (group 3), respectively. After 1 year, group comparison results were statistically significant (P G 0.0001). Linear trend test was also statistically significant (P G 0.0001), pointing out larger healing from group 1 to group 3. After 5 years, teeth were classified into 2 groups on the basis of root-end filling material used. Clinical success was 90.8% (197 teeth) in the silver amalgam group versus 96% (309 teeth) in the mineral trioxide aggregate group (P G 0.00214). Multiple logistic regression analysis found that surgical technique was independently associated to tooth healing. In conclusion, modern apicoectomy resulted in a probability of success more than 5 times higher (odds ratio, 5.20 [95% confidence interval, 3.94Y6.92]; P G 0.001) compared with the traditional technique.
