AI-Powered Identification of Osteoporosis in Dental Panoramic Radiographs: Addressing Methodological Flaws in Current Research.

Osteoporosis, a systemic skeletal disorder, is expected to affect 60% of women over 50. While dual-energy X-ray absorptiometry (DXA) scans are the current gold standard for diagnosis, they are typically used only after fractures occur, highlighting the need for early detection tools. Initial studies have shown panoramic radiographs (PRs) to be a potential medium, but these have methodological flaws.

Assessment of the occurrence of apical periodontitis and endodontically treated/non-treated teeth in a Lower Austrian patient population treated for osteoporosis: a cohort study.

Introduction: Osteoporosis (OP) is a bone disease linked to low bone mass and heightened fracture risk. Apical periodontitis (AP) is an inflammation of the apical periodontium, visible on radiographs, often associated with infection or necrosis of the root canal system. Both conditions, AP and OP, share inflammation and ageing as common factors, warranting exploration of their potential interactions.

Partial tooth formation diagnosed eight years after an extraction of the maxillary third molar germ in a complete crown formation stadium: A case report.

Introduction: Orthodontic purposes, such as the prevention of anterior crowding, are common and controversial indications for surgical removal of the third molar (M3) germ in young patients. A higher tooth bud position and the risk of tooth displacement in the infratemporal fossa when surgery of the maxillary M3 germ is planned makes the success of germectomy unlikely with little benefit. A rare complication of maxillary M3 germ surgery is partial tooth building after germectomy.

Clinical and radiological documentation of complete remodeling of the mandibular bone after the enucleation of a large odontogenic keratocyst: 15 years follow-up of a unique case - A case report.
