Randomized clinical trial of root‐end resection followed by root‐end filling with mineral trioxide aggregate or smoothing of the orthograde gutta‐percha root filling – 1‐year follow‐up

Abstract

The results from this RCT emphasize the importance of placing a root-end filling after root-end resection. Teeth treated with MTA had significantly better healing (96%) than teeth treated by smoothing of the orthograde GP root filling only (52%).

Outcome of Endodontic Surgery: A Meta-analysis of the Literature—Part 2: Comparison of Endodontic Microsurgical Techniques with and without the Use of Higher Magnification

“…Of the 101 citations obtained after abstract and full-text review, a total of 14 records were included in this second part of the meta-analysis (10-23). Data from 2 articles were used for CRS as well as EMS (12,15), bringing the total number to 7 datasets for CRS (10-16) and 9 datasets for EMS (12,15,(17)(18)(19)(20)(21)(22)(23). There were 6 randomized controlled trials (best) (13,15,16,18,21,23), 2 prospective studies with concurrent controls (better) (12,22), and 6 prospective case studies (average) (10,11,14,17,19,20) included into the analysis ( Table 1).…”

“…1) (2). The detailed remedial solution for the incorporation of Christiansen et al (23), which had a 100% success rate and thus presented with a statistical problem as the inverse variance was undefined, was described in part 1 of this investigation. Briefly, the remedial solution adjusted the individual success rates to 0.99 and computed the inverse variance from the adjustment (107).…”

Periapical Tissue Response After Use of Intermediate Restorative Material, Gutta-Percha, Reinforced Zinc Oxide Cement, and Mineral Trioxide Aggregate as Retrograde Root-End Filling Materials: A Histologic Study in Dogs

“…2 In addition to the sealing properties of the material used, the material has to be biocompatible with the surrounding tissue.…”

Calcium silicate materials in endodontics

“…1,2 In both instances, there was also evidence of cementum covering the restoration site. Since these initial studies, there are records of good clinical success when it has been used as a root-end filling material 3,4 (Figures 1 and 2) for root perforation repair, 5 direct pulp capping, However, because the grey colour affected aesthetics, the composition of MTA was altered to reduce the iron content and become more tooth-coloured. This was introduced as white ProRoot MTA in March 2002 13 ( Figure 5).…”
