Bone mineral density (BMD) is related to oral health. This study investigated how changes in BMD influence tooth loss risk and dental caries prevalence. This cross-sectional observational study included 224 people (199 males and 25 females). The BMD scores of the participants’ lumbar spine, femoral neck, and total hip were categorized as normal, osteopenia, or osteoporosis. Oral health was assessed using the Decayed, Missing, Filled Teeth (DMFT) index and Oral Hygiene Index-Simplified (OHI-S) scores. Based on the number of surviving teeth, the participants were categorized into low (< 20) and high (≥ 20) groups. Differences between groups were assessed using independent sample T tests and one-way analysis of variance. The normal, osteopenia, and osteoporosis groups comprised 72, 87, and 65 participants, respectively. The OHI-S scores showed no notable variations across the groups. The DMFT index scores were highest (18.69) in the osteoporosis group and lowest (14.08) in the normal group (p < 0.001). Although the number of remaining teeth was lower in the osteoporosis and osteopenia groups compared to the normal group (p < 0.001), that in the osteopenia group approximated the normal group, but was substantially higher than in the osteoporosis group. The group with the lowest number of remaining teeth had lower total hip T-scores, despite significantly higher DMFT indexes (p < 0.001). Tooth loss and dental decay rates were significantly high in patients with osteoporosis. Although bone resorption during osteopenia is not excessive, it constitutes a crucial risk factor for dental health. Therefore, attention must be paid to bone resorption treatment in patients with osteopenia.

Background and Objectives: Shoulder pain, mainly involving rotator cuff tears, is a common type of musculoskeletal pain that significantly impairs quality of life. Arthroscopic rotator cuff repair has become the gold standard for treating symptomatic, full-thickness rotator cuff tears. Double-row repair techniques are widely used because of their superior fixation and healing results. However, fewer implants may reduce treatment costs and raise questions about the impact on clinical outcomes and re-tear rates. This study compares the functional outcomes and re-tear rates of two transosseous-like double-row repair techniques: one anchor and one push lock (Group 1), and two anchors and two push locks (Group 2). Materials and Methods: A prospective, randomized, single-blind study was conducted on 53 patients undergoing arthroscopic repair for crescent-shaped rotator cuff tears (3–5 cm). Before surgery and 24 months after surgery, patients were evaluated for shoulder function using Constant–Murley scores and shoulder abduction angles. MRI was used to assess re-tear rates. Results: Both groups showed significant postoperative improvement in Constant scores (Group 1: 84.1; Group 2: 84.0; p > 0.05). Re-tear rates were slightly higher in Group 1 (23.1%) than in Group 2 (18.5%), but this was not statistically significant (p > 0.05). Shoulder abduction angles improved similarly between groups, with no significant difference in outcome. Despite higher costs and longer operative times, the two-anchor technique provided more stable fixation, but its functional outcomes were comparable to the single-anchor method. Conclusions: Using fewer implants in a double-row repair provides comparable functional outcomes and re-tear rates, and offers surgeons a cost-effective alternative, especially at the beginning of their learning curve. However, the two-anchor technique may be more beneficial in cases requiring improved mechanical stability. These findings provide valuable information to balance cost and effectiveness in rotator cuff repair.

The necessity of antibiotic prophylaxis before dental procedures in arthroplasty patients remains unsupported by strong evidence. The aim of this study was
