Insomnia and Post-Dental Surgery Pain: A Prospective Study

The purpose of this prospective observational study is to evaluate the relationship between preoperative sleep disturbances-specifically insomnia-and postoperative pain intensity following oral surgical procedures. Recent scientific literature highlights a bidirectional relationship between sleep disorders and pain in dentistry, suggesting that disturbed sleep may actively exacerbate subsequent pain perception. Although postoperative pain, swelling, and masticatory difficulties are common after dental extractions, clinical data investigating the direct impact of preoperative sleep quality on these surgical outcomes remain scarce. This study will enroll adult patients undergoing routine dental extractions and allocate them into two cohorts based on their baseline sleep quality: patients without preoperative sleep disturbances and patients with preoperative sleep disturbances. Pain levels and sleep parameters will be assessed using validated questionnaires before the surgery and at a 7-day follow-up. The primary objective is to determine whether the presence of preoperative insomnia leads to a significant increase in perceived postoperative surgical pain.

Mix of Demineralized Freeze-Dried Bone Allograft and Deproteinized Bovine Bone Mineral: a Possible Solution for Alveolar Ridge Preservation?

The purpose of the study is to compare a new grafting material for alveolar ridge preservation to a commonly used and well studied material. Alveolar ridge dimensions as well as histology will be compared.

Human Placenta Extract Use in Socket Preservation

This split-mouth pilot study evaluates the effectiveness of flowable decellularized Human Placental Connective Tissue Matrix (HPCTM) in alveolar ridge preservation following tooth extraction. Patients will receive HPCTM mixed with allograft particles in one extraction socket and allograft particles solely in the contralateral socket. The primary outcome is to assess dimensional changes in the alveolar ridge in terms of soft tissue shrinkage using a super-imposed intra-oral scans taken at baseline , day 10, 21 and 30 post-op and bone resorption rate by comparing pre-op and 4 months post-op cone beam computed tomography scans. Secondary outcomes include clinical soft tissue healing evaluation and commentary. The HPCTM used in this study is regulated by the US FDA under Section 361 of the Public Health Service Act (21 CFR Part 1271.10(a)).
