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 .
Dentine-bonded resin composite (Retroplast) for root-end filling: a prospective clinical and radiographic study with a mean follow-up period of 8 years.
AIM To evaluate treatment outcome after using a resin composite ( Retroplast , RP ) in combination with a dentine-bonding agent ( GLUMA ) as root-end filling material after 1 year as well as after more than 5 years ( final examination ) . Also , the influence of various pre- , intra- and postoperative factors on the treatment outcome was studied . METHODOLOGY All patients ( 87 ) undergoing root-end resection consecutively treated by root-end filling with RP on an incisor , canine , pre-molar , or first molar ( 87 teeth , 118 roots ) were initially enrolled in the study .  RP was applied on the entire resected surface that was prepared to a slightly concave shape and after conditioning with EDTA and GLUMA . The treatment outcome involving subjective , clinical and radiographic parameters was evaluated after 1 year and at the final examination . A total of 27 patients ( 36 roots ) were excluded from the study because of unavailability of follow-up ( 19 ) and extraction of the operated tooth for reasons other than failed surgery ( 8) . Consequently , 60 patients ( 82 roots ) were included in the final material . The mean follow-up period at the final examination was 8 years ( range : 6.5 - 9 years ) . RESULTS The radiographic evaluation at the final examination revealed that 77 % , 5 % , 7 % and 11 % of the treated roots were characterized by complete , incomplete , uncertain and unsatisfactory healing , respectively . A total of 95 % of the roots classified as completely healed at the 1-year control were also completely healed at the final examination . Two roots ( 5 % ) showing complete healing at the 1-year control revealed unsatisfactory healing at the final examination because of displaced or lost RP-filling . Moreover , 60 % of the roots with uncertain healing at the 1-year control demonstrated complete or incomplete healing at the final examination . The classification according to subjective , clinical and radiographic parameters revealed that 78 % of the teeth were characterized by a successful treatment outcome at the final examination . Evaluation of the influence of various pre- , intra- and postoperative factors on the treatment outcome revealed that the radiographic classification at the final examination was exclusively influenced by the radiographic classification at the 1-year control ( P < 0.001 ) . CONCLUSIONS The present long-term study indicates that RP can be used for root-end filling with a successful treatment outcome
