this study was aimed to investigate the use of panoramic radiography in patients with low bone mineral density (bmd) in order to diagnose and prevent osteoporotic fractures. panoramic radiographs of 60 patients  (20 men and 40 women) aged from 40 to 70 years with cortical thicknesses of less than 3 mm in the mandibular angle were selected from patients referred to a dentomaxillofacial radiology...

A study was conducted to evaluate the effects of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in...

Biomineralization is a dynamic, complex, lifelong process by which living organisms control precipitations of inorganic nanocrystals within organic matrices to form unique hybrid biological tissues, for example, enamel, dentin, cementum, and bone. Understanding the process of mineral deposition is important for the development of treatments for mineralization-related diseases and also for the i...

reconstruction methods are an essential prerequisite for functional rehabilitation of the stomatognathic system. plasma rich in growth factors (prgf) offers a new and potentially useful adjunct to bone substitute materials in bone reconstructive surgery. this study was carried out to investigate the influence of prgf and fibrin membrane on regeneration of bony defects with and without deprotein...

Twenty-seven patients were randomized into two treatment groups following single tooth extraction in the incisor, canine and premolar area. In the test group, the alveolar socket was grafted with Straumann Bone Ceramic (SBC), while in the control group, Bio-Oss deproteinized bovine bone mineral (DBBM) was applied. In both groups, a collagen barrier was used to cover the grafting material. Compl...

both anorganic bovine bone (abb) and β-tricalcium phosphate (β-tcp) are used in clinical practice as bone substitute materials, but there is limited data comparing these two materials in standardized defects. the aim of this study was to histologically evaluate the effectiveness of abb and β-tcp in the healing of experimentally induced bone defects.eighteen bone defects were created on the calv...

from the last few years, the inclusion of microbial phytase in poultry diets has increased significantly, mainly in response to heightened concerns over phosphorus pollution of the environment and as cheaper means to make phosphorus available to birds from phytate. phytate is the major form of phosphorus, abundantly found in cereal grains, beans and oilseed meals used in poultry diet but the mo...

OBJECTIVE An experiment was conducted to evaluate dietary supplemental trace mineral source and deletion on mineral content in tissues. METHODS Weanling crossbred pigs (n = 144; 72 barrows and 72 gilts; body weight [BW] = 7.4±1.05 kg) were used. A basal diet was prepared, and trace mineral premix containing either inorganic (ITM) or organic (OTM) trace minerals (Cu, Fe, Mn, and Zn) was added ...

PURPOSE Fibronectin (FN) has been shown to stimulate bone regeneration in animal models. The aim of this study was to evaluate the capacity of bovine bone mineral coated with synthetic oligopeptides to enhance bone regeneration in rabbit calvarial defects. METHODS Oligopeptides including fibrin-binding sequences of FN repeats were synthesized on the basis of primary and tertiary human plasma ...
