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 .
Comparative evaluation of platelet-rich plasma and guided tissue regeneration membrane in the healing of apicomarginal defects: a clinical study.
INTRODUCTION The aim of the study was to compare the healing responses of platelet-rich plasma ( PRP ) , PRP + a collagen sponge , and a collagen membrane used as guided tissue regeneration ( GTR ) material s for the treatment of apicomarginal defects . METHODS Thirty patients with suppurative chronic apical periodontitis and apicomarginal communication were selected and allocated r and omly into three groups according to the barrier technique to be used during periradicular surgery : the collagen membrane group , the PRP group , and the PRP + collagen sponge group .  Clinical and radiographic measurements were determined at baseline and every 3 months after surgery up to 1 year . Cases were defined as healed when no clinical signs or symptoms were present , and radiographs showed complete or incomplete ( scar tissue ) healing of previous radiolucencies . RESULTS The PRP and PRP + collagen sponge groups depicted 83.33 % and 88.89 % healing , respectively , in terms of combined clinical -radiographic healing as compared with 80 % in the collagen membrane group . All the three treatments showed highly significant ( P < .05 ) reductions in the periodontal pocket depth ( PD ) , the clinical attachment level ( CAL ) , the gingival margin position ( GMP ) , the size of the periapical lesion , the percentage reduction of the periapical rarefactions , and periapical healing . No significant differences between the three groups were evident for these parameters ( P > .05 ) . CONCLUSIONS GTR applied to apicomarginal defects using PRP or PRP + collagen sponge lead to similar enhancements of the clinical outcome of periradicular surgery in terms of periapical healing , gain of periodontal support , PD reduction , and PRP may be an alternative treatment for GTR membrane in the treatment of apicomarginal defects
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 .
