Oro-dental and cranio-facial characteristics of osteogenesis imperfecta type V.

Osteogenesis imperfecta (OI) type V is an ultrarare heritable bone disorder caused by the heterozygous c.-14C > T mutation in IFITM5. The oro-dental and craniofacial phenotype has not been described in detail, which we therefore undertook to evaluate in a multicenter study (Brittle Bone Disease Consortium).

Preventive Dental Treatment Workload/Costs to Mitigate Antiresorptive Bone Medication-related Osteonecrosis Risk.

Purpose: To determine the extent of dental disease and associated treatment costs designed to mitigate the risk of medication-related osteonecrosis of the jaws (MRONJ) among older, socially disadvantaged veterans prior to physician's administration of antiresorptive medication for osteoporosis or malignant bone disease.

Materials And Methods: This prospective study based on over seven years (2008-2015) of data describes the type and volume of disease, treatment, work-load measures, and costs using Veterans Affairs databases.

Results: One hundred fifty-two outpatients (94% male, mean age 69 ± 12 years) were referred by physicians for clinical/radiographic examination and treatment.

Pathophysiology of Osteonecrosis of the Jaws.

Osteonecrosis of the jaw (ONJ) is a multifactorial disease in patients with primary or metastatic bone malignancy or osteoporosis undergoing systemic antiresorptive therapy, where pathophysiology has not yet been fully determined. The staging of ONJ is based on severity of symptoms and extent of clinical and radiographic findings. Treatment strategies range from conservative local wound care to aggressive resective surgery of all necrotic bone.

High C-Terminal Cross-Linking Telopeptide Levels Are Associated With a Minimal Risk of Osteonecrosis of the Jaws in Patients Taking Oral Bisphosphonates and Having Exodontia.

Purpose: The clinical significance of bone turnover marker C-terminal cross-linking telopeptide (CTX) levels less than 150 pg/mL among recipients of oral bisphosphonate (OBP) medications who develop osteonecrosis of the jaws (MRONJ) after exodontia is unclear. We searched the published data to determine the prevalence of such levels and the association, if any, with development of MRONJ.

Materials And Methods: A systematic review of published studies in the PubMed database was undertaken to ascertain the prevalence of preoperative, fasting CTX levels less than 150 pg/mL among recipients of OBP scheduled for exodontia and to determine whether such levels are associated with the development of postoperative MRONJ.
