Conclusions : The probability for success for EMS proved to be significantly greater than the probability for success for RES , providing best available evidence on the influence of cavity preparation with ultrasonic tips and /or SuperEBA ( Keystone Industries , Gibbstown , NJ ) , IRM ( Dentsply Sirona , York , PA ) , MTA , or silicate cements as root‐end filling material instead of a shallow cavity preparation and placement of a resin‐based material .
HIGHLIGHTSEndodontic microsurgery ( EMS ) with the use of high‐magnification ultrasonic root‐end preparation and root‐end filling with SuperEBA , IRM , MTA , or other calcium silicate cements has a high probability of success .
Resin‐based endodontic surgery with the use of high‐magnification preparation of a shallow concave root‐end cavity with bonded resin‐based root‐end filling material performed less favorably than EMS
Introduction : The aim of the present study was to investigate the influence of root‐end preparation and filling material on endodontic surgery outcome .
[Periradicular surgery with endoscopy--a clinical prospective study].
Using an endoscope in periradicular surgery provides an impressive optical enlargement and may lead to better clinical diagnostics and a high rate of success . Aims of this investigation were examining this hypothesis as well as detecting influencing factors . In 2002 and 2003 , 114 teeth of 91 patients were root-end resected using endoscope .  Before surgery , the tooth , number of resected root-ends , content of root channels , clinical diagnosis and moment of surgery were recorded . Patients were controlled one year after surgery and success was evaluated as a summary of clinical and radiological findings . Four patients did not reappear for the control examination . Out of 110 teeth , treatment was successful in 91.8 % and failed in 7.3 % . 0.9 % could not be classified . Statistically , more failures were noted after periradicular surgery in molars . The rate of success increased during the study by means of a learning curve . The results confirm the hypothesis that where using an endoscope periradicular surgery is highly successful
Conclusions : The probability for success for EMS proved to be significantly greater than the probability for success for RES , providing best available evidence on the influence of cavity preparation with ultrasonic tips and /or SuperEBA ( Keystone Industries , Gibbstown , NJ ) , IRM ( Dentsply Sirona , York , PA ) , MTA , or silicate cements as root‐end filling material instead of a shallow cavity preparation and placement of a resin‐based material .
