Retrospective follow‐up assessment of prognostic variables associated with the outcome of periradicular surgery

Abstract

The findings of this study suggest that whilst the quality of both the coronal restoration and the root-end filling might be the foremost prognostic variables in periradicular surgery, there are synergistic biological interactive and mutually confounding effects with respect to root-end resection bevel and preoperative signs and/or symptoms that may be also associated with an increased proportion of failures after periradicular surgery.

The resection angle in apical surgery: a CBCT assessment

“…The effect of the resection angle on healing outcome has not been evaluated in detail in clinical studies. In a retrospective study [17] of prognostic variables, 116 teeth treated with apical surgery had a Bminimal^bevel of 0°-10°, whereas 55 teeth had a Bpronounced^bevel >10°. The rate of failures was 10.3 % in teeth with a minimal bevel, but 29.1 % in teeth with a pronounced bevel.…”

Mineral trioxide aggregate and other bioactive endodontic cements: an updated overview – part II: other clinical applications and complications

“…Type of root‐end filling material is one of the variables that may have an impact on the outcome of periapical surgery (von Arx , Villa‐Machado et al . ). Placement of a root‐end filling is associated with a significantly better outcome compared to smoothing a gutta‐percha root filling during periapical surgery (Christiansen et al .…”

Influence of Size and Volume of Periapical Lesions on the Outcome of Endodontic Microsurgery: 3-Dimensional Analysis Using Cone-beam Computed Tomography

“…In other studies, the outcome was not correlated with the size of the periapical lesion (8)(9)(10). Widening the scope to traditional apical surgery, some authors noted that the size of the lesion was related to the outcome (11,12); however, opposite results were reported as well (13,14).…”
