Operating microscope use during alveolar ridge preservation tied to improved healing: Study
Operating microscope use during alveolar ridge preservation tied to granulomatous tissue removal and improved healing suggests a study published in the Journal of Periodontology.
The use of the operating microscope (OM) for extraction and alveolar ridge augmentation (ARP) is increasing due to enhanced magnification and illumination. The primary objective was to compare the wound healing and crestal bone quality after the use of OM and dental loupes (DL) for ARP. Forty non-molar teeth with periapical lesions in need of extraction and ARP from 33 patients were randomly assigned to 2 groups: DL (control) or OM (test). All procedures were performed by 1 surgeon and assessments done by masked examiners. ARP was performed with an allograft and a resorbable collagen membrane. The presence of granulomatous tissue remnants after debridement was recorded. Cone-beam computed tomography (CBCT) and ultrasound (US) scans were taken during the healing phase up to 16-week visits. Bone cores were retrieved from implant osteotomies for histologic analysis. Patient-reported outcome measurements (PROMs) were assessed. Results: All patients completed all study visits except 1 who dropped out before the last visit. After socket debridement, the test group exhibited significantly fewer sites with tissue remnants (p = 0.01) and a better healing score at 2-week (p = 0.04) and 4-week (p = 0.01) time points. There were no significant differences in 12-week crestal bone healing by histology (p = 0.1), US (p = 0.85), and CBCT healing (p = 0.64) at 12 weeks, as well as PROMs (p > 0.1). Within the limitation of the study, the use of OM for ARP resulted in significantly fewer tissue remnants and favorable early visual wound healing. CBCT and US-derived-crestal bone quality did not show a difference between the 2 group
