Aim: The aim of this prospective study was to evaluate the clinical pattern of post-extraction wound healing with a view to identify the types, incidence, and pattern of healing complications following non-surgical tooth extraction.
Study Design: A total of 311 patients, who were referred for non-surgical (intra-alveolar) extractions, were included in the study. The relevant pre-operative information recorded for each patient included age and gender of the patient, indications for extraction, and tooth/teeth removed. Extractions were performed under local anesthesia with dental forceps, elevators, or both. Patients were evaluated on the third and seventh postoperative days for alveolus healing assessment. Data recorded were: biodata, day of presentation for alveolus healing assessment, day of onset of any symptoms, body temperature (degrees C) in cases of alveolus infection, and presence or absence of pain.
Results: Two hundred eighty-two patients (282) with 318 extraction sites were evaluated for alveolus healing. Healing was uneventful in 283 alveoli (89%), while 35 alveoli (11%) developed healing complications. These complications were: localized osteitis 26 (8.2%); acutely infected alveolus 5 (1.6%); and an acutely inflamed alveolus 4 (1.2%). Females developed more complications than males (p=0.003). Most complications were found in molars (60%) and premolars (37.1%). Localized osteitis caused severe pain in all cases, while infected and inflamed alveolus caused mild or no pain. Thirty patients (12%) among those without healing complications experienced mild pain.
Conclusions: Most of the post-extraction alveoli healed uneventfully. Apart from alveolar osteitis (AO), post-extraction alveolus healing was also complicated by acutely infected alveoli and acutely inflamed alveoli. This study also demonstrated a painful alveolus is not necessarily a disturbance of post-extraction site wound healing; a thorough clinical examination must, therefore, be made to exclude any of the complications.

Biologically-oriented alveolar ridge preservation to correct bone dehiscence at immediate implant placement.

Background: The purpose of the present case study is to describe the application of a modification of the Biologically-oriented Alveolar Ridge Preservation (BARP) principles in cases of peri-implant bone dehiscence (PIBD) due to a compromised alveolus at immediate implant placement (IIP).
Methods: The technique is based on the stratification of three layers: a deep layer with a collagen sponge (CS) in the apical part of the alveolus (where the buccal bone plate was still present) to support the blood clot; a graft layer to correct the PIBD; and a superficial collagen layer to cover the graft thus providing space and enhancing clot/graft stability. Healing was obtained by primary closure.

Aim: This study aims to evaluate the impact of platelet-rich fibrin (PRF) and platelet-rich plasma (PRP) on pain, swelling, trismus, soft tissue healing and bone regeneration following mandibular third molar extraction.
Material And Methods: A systematic review was conducted from a period of January 2014 to June 2024 using PRISMA guidelines. The search strategy included databases such as Scopus, PubMed, Google Scholar, and Cochrane Central Register of Controlled Trials, using key terms related to "PRF", "PRP", oral surgery, and third molars.
Abaloparatide Enhances Bone Regeneration in Extraction Socket Dental Implant Defects: An Experimental In Vivo Study.

Objective: Abaloparatide (ABL) is a synthetic parathyroid hormone-related protein analog developed as an anabolic drug to treat osteoporosis. ABL increases bone mineral density (BMD) of the long bones and spine; however, the influence of ABL on alveolar bone regeneration remains unknown. This study assessed the effects of systemic ABL administration on tooth extraction socket healing and dental implant osseointegration in a preclinical rodent model.

Tooth extraction is physiologically followed by resorption of alveolar bone. Surgical method which aims to minimise this reduction in alveolar bone with a goal to provide enough bone volume for dental implant insertion is called socket preservation. The purpose of this article was to asses clinical, histomorphometric and histological results of socket preservation conducted with natural bovine bone substitute with hyaluronate.

The purpose of this case report is to examine the management of vestibular bone fenestration during alveolar socket preservation using the Periosteal Inhibition (PI) approach. Here, for the first time, the PI technique, which has been shown to be successful in maintaining intact cortical bone, is examined in the context of a bone defect. : After an atraumatic extraction of a damaged tooth, a vestibular bone fenestration was discovered in the 62-year-old male patient.
