Bone is a dynamic tissue. Skeletal bone integrity is maintained through bone modeling and remodeling. The mechanisms underlying this bone mass regulation are complex and interrelated. An imbalance in the regulation of bone remodeling through bone resorption and bone formation results in bone loss. Chronic inflammation influences bone mass regulation. Inflammation-related bone disorders share many common mechanisms of bone loss. These mechanisms are ultimately mediated through the uncoupling of bone remodeling. Cachexia, physical inactivity, pro-inflammatory cytokines, as well as iatrogenic factors related to effects of immunosuppression are some of the common mechanisms. Recently, cytokine signaling through the central nervous system has been investigated for its potential role in bone mass dysregulation in inflammatory conditions. Growing research on the molecular mechanisms involved in inflammation-induced bone loss may lead to more selective therapeutic targeting of these pathological signaling pathways.

Mandibular trabecular bone pattern before and two years after medical or surgical obesity treatment in young Swedish women.
Clin Oral Investig
January 2025
Department of Behavioral and Community Dentistry, Institute of Odontology, Sahlgrenska Academy, University of Gothenburg, P.O. Box 450, Gothenburg, SE-40530, Sweden.
Objective: To investigate if changes in body mass index (BMI) result in changes of the mandibular trabecular bone structure.
Materials And Methods: Females (18-35 years at baseline, mean BMI 42,3) were followed from before (n = 117) until two years (n = 66) after obesity treatment (medical or surgical). The mandibular bone trabeculation was classified as sparse, dense, or mixed on intraoral radiographs (Lindh's index).

Objective: To investigate the predictive ability of the MRI-based vertebral bone quality (VBQ) score for pedicle screw loosening following instrumented transforaminal lumbar interbody fusion (TLIF).
Methods: Data from patients who have received one or two-level instrumented TLIF from February 2014 to March 2015 were retrospectively collected. Pedicle screw loosening was diagnosed when the radiolucent zone around the screw exceeded 1 mm in plain radiographs.

Article Synopsis
- The study aimed to evaluate the effectiveness of antimicrobial photodynamic therapy (aPDT) combined with mechanical debridement (MD) in treating peri-implantitis in patients undergoing chemotherapy compared to systemically healthy patients.
- Both patient groups were assessed; however, results showed no significant differences in key measurements (plaque and gingival indices, probing depth, and bone loss) between the two groups at both baseline and three-month follow-up.
- Overall, the findings indicated that adding aPDT to MD did not lead to enhanced treatment outcomes for peri-implantitis in either chemotherapy patients or systemically healthy individuals.

This study aims to provide an initial database to gain more detailed knowledge of the trabecular and cortical bone structure of pelvic and femur bones in cats and smaller dogs. Additionally, the bony microarchitecture between cats and smaller dogs was compared to identify possible differences between those species. These findings could potentially improve the development of non-cemented total hip replacement (THR).

Purpose: The aim of this study was to investigate the correlations between areal bone mineral density (aBMD) and body composition measured by two dual-energy X-ray absorptiometers (DXA), the DMS Stratos® (STR) and the Hologic Horizon A® (HRZ), and then generate cross-calibration equations between the two scanners.
Methods: Repeat scans were obtained from 251 adults (85 % female), 36 ± 14 years old with mean body mass index (BMI) of 28.7 ± 11.
