Purpose: to evaluate the outcome of surgical endodontic treatment performed by a modern technique and to evaluate the factors influencing the outcome by means of a meta-analysis.
N= 11 studies
Materials/Methods:
•Inclusion :
(1) RCTs or prospective case series;
(2) surgical endodontic treatments performed by a modern technique
(3) periapical lesions
(4) at least 1-year follow-up
(5) outcome evaluated according to Rud et al and/or Molven et al. •Exclusion
(1) retrospective studies, case reports, review articles expert opinions;
(2) surgical endodontic treatment performed without using a modern technique
(3) re-surgery cases
(4) teeth presented with apico-marginal defects & periodontal disease (periodontal pockets and/or mobility)
(5) root fractures and root perforations;
(6) less than 1-year follow-up; and
(7) outcome evaluated not according to Rud et al and/or Molven et al
•The full texts of the studies were reviewed by 3 independent observers. •Success was considered as a complete or incomplete healing.
Most highlighted Results:
1.71 articles were identified, ending up with 11 articles meeting the inclusion & exclusion criteria.
2.The pooled percentage of success (complete healing and incomplete healing) was found to be 91.6%.
3.The pooled percentage of failure was found to be
4.7%. 4.The rest was uncertain healing 3.7%.
5.Age, gender, tooth type, root-end filling material, and magnification type had no significant effect on the proportion of success
Clinical significance:
•Surgical endodontic treatment performed by using the modern technique is a predictable treatment.
