Zinc supplementation improves bone density in patients with thalassemia: a double-blind, randomized, placebo-controlled trial

submitted by: efung
BACKGROUND: Patients with thalassemia major (Thal) frequently have low plasma zinc, which has been associated with low bone mass. OBJECTIVE: The objective was to determine the effect of zinc supplementation on bone mass in patients with Thal. DESIGN: Forty-two subjects (21 females aged 10-30 y) with Thal and low bone mass were randomly assigned to receive 25 mg Zn/d or placebo. Bone mineral content (BMC) and areal bone mineral density (aBMD) were assessed by using dual-energy X-ray...

Extraction sockets: erratic healing impeding factors

submitted by: freetist
Aim: The aim of this exploratory study was to analyse prevalence of extraction sockets showing erratic healing and evaluate factors potentially impeding healing. Methods: Erratic healing was defined as extraction sites showing clinical observations of fibrous scar tissue occupying the extraction site rather than bone following 12 or more weeks of healing. Computerized tomography was used to evaluate characteristics and calculate Hounsfield unit scores for sites showing erratic healing....
