Purpose: to Investigate the outcomes of contemporary root-end surgery (CRS) techniques with only loupes or no visualization aids compared with endodontic microsurgery using the same instruments and materials but with high-power magnification (surgical operating microscope or the endoscope) EMS. The influence of the tooth type on the outcome was also investigated.
N=16 data sets
•3 Electronic data bases were searched to identify human studies from 1966 to October 2009 in 5 (different languages, journals) through 3 independent reviewers .
•Inclusion criteria: same as part 1 except (minimum follow up period of 12 months).
Most highlighted Results:
•The CRS group included 7 studies with a weighted pooled success rate of 88%.
•The EMS group included 9 studies with a weighted pooled success rate of 94%.
This study providing best available evidence on the influence of high-power magnification rendered by the dental operating microscope or the endoscope.
