Treatment of enucleated odontogenic jaw cysts: a systematic review

Abstract

In this systematic review, we aimed to assess the impact of filling or not filling enucleated odontogenic jaw cysts on bony defect consolidation. In terms of filling, we aimed to assess which is the best filling material based on current evidence. An electronic search was performed using PubMed, Embase, and MEDLINE databases with the logical operators: "odontogenic cysts" AND "jaw cysts" AND "treatment AND therapy." Thirteen studies with primary enucleation (6 with filling and 7 without filling) were included. In terms of filling, either synthetic bone substitutes or autologous bone were used. The primary outcome was bony regeneration judged by radiographic follow-up measurements. Two-dimensional (2-D) radiographic follow-up measurements (densitometry) revealed a bone density increase and comparable bone regeneration in both groups. Because of the low number of studies and the heterogeneity of the included data, evidence-based treatment recommendations cannot be given at this time. Also, outcomes based on 2-D measurements should be interpreted with caution. However, the following factors are suggested as having an impact on bony defect consolidation: defect size, defect configuration, the preservation of the periosteum, and localization (upper or lower jaw). Prospective comparable clinical studies with a 3-dimensional follow-up are needed.
