Purpose:  to report the healing outcome of two different methods of root-end preparation & filling in apical surgery, MTA & an adhesive resin composite Retroplast. 


n: 339 teeth distributed non randomly to GP.1.MTA (173 teeth) and GP.2.Retroplast (166 teeth)

•Patients needing apical surgery were enrolled form 2001-2007. Teeth with through & through lesions, roots with perforations or with apicomarginal lesions were excluded.

•F/U radiographs were evaluated after 1 year by 3 examiners and criteria of healing followed Molven and Rud classification.

Most highlighted Results: 

•The Retroplast group had more mandibular molars than the MTA group. In contrast MTA group included more anterior teeth than the Retroplast group.

•The overall rate of healed cases was 85.5%.

•Significantly higher healing rate of MTA 91% when compared with Retroplast 80%.

•Retroplast healing rate varied in different types of teeth lowest was 67% in mandibular Pm and 68% in mandibular M Table.1.

•Rates of healed cases in re-surgeries were lower than in the first time surgeries for all teeth.

Clinical significance:

•MTA success rate was higher and constant than Retroplast.
