Results In both jaws, ARP prevented ridge height loss, but

ridge width was significantly reduced by approximately 2.5mm. Healing time, initial clinical attachment loss and amount of keratinized tissue at extraction site were identified as determinants of ridge height outcome. Buccal plate thickness and tooth root length were identified as determinants of ridge width outcome. In addition, initial ridge width was positively correlated with ridge width loss. Micro-CT revealed greater mineralization per unit volume in new bone compared with existing bone in mandible (p<0.001). Distributions of residual graft, new cellular bone and immature tissue were similar in both jaws. Conclusion Within the limitations of this study, the results indicate that in different anatomic locations different factors may determine ARP outcomes. Further studies are needed to better BTSA1 mouse understand determinants of ARP outcomes.”
“Background: One in four Swedish women suffers a hip fracture yielding high morbidity and mortality. We wanted to revalidate a 4-item clinical risk score and evaluate a portable heel bone mineral density (BMD) technique regarding hip and fragility fracture risk among elderly women.\n\nMethods: In a population-based prospective cohort study we used clinical risk factors from a baseline questionnaire and heel BMD to predict

a two-year hip and fragility fracture outcome for women, in a fracture preventive program. Calcaneal heel BMD was measured Selleck MX69 by portable dual X-ray laser absorptiometry (DXL) and compared to hip BMD, measured with stationary dual X-ray absorptiometry (DXA) technique.\n\nResults: Seven women suffered hip fracture and 14 Pevonedistat nmr women fragility fracture/s (at hip, radius, humerus and pelvis) among 285 women; 60% having heel BMD <=-2.5 SD. The 4-item FRAMO (Fracture and Mortality) Index combined the clinical risk factors age >= 80 years, weight <60 kg, prior fragility fracture, and impaired rise-up ability. Women having 2-4 risk factors showed odds ratio (OR) for hip fracture of 5.9 and fragility fracture of 4.4. High risk group hip fracture risk was 2.8% annually compared to 0.5% for the low risk majority (69%). Heel BMD showed hip

fracture OR of 3.1 and fragility fracture OR of 2.6 per SD decrease. For 30 DXA assessed participants mean hip BMD at -2.5 SD level corresponded to a lower BMD at the heel. Five of seven hip fractures occurred within a small risk group of 32 women, identified by high FRAMO Index + prior fragility fracture + heel T-score <=-3.5 SD.\n\nConclusions: In a follow-up study we identified high risk groups for hip and fragility fracture with our plain 4-item risk model. Increased fracture risk was also related to decreasing heel BMD in calcaneal bone, measured with a mobile DXL technique. A combination of high FRAMO Index, prior fragility fracture, and very low BMD restricted the high risk group to 11%, among whom most hip fractures occurred (71%).
