We have developed a combinatorial method for determining optimum tissue scaffold composition for several X-ray imaging techniques. X-ray radiography and X-ray microcomputed tomography enable non-invasive imaging of implants in vivo and in vitro. However, highly porous polymeric scaffolds do not always possess sufficient X-ray contrast and are therefore difficult to image with X-ray-based techni...

primary antibody deficiencies (pad) are a group of immune system disorders, associated with decreased levels of secretory and protective immunoglobulins. because of the important role of immunoglobulins in the protection  of oral cavity, patients with pads  are more susceptible to dental caries or oral manifestations. this study was performed  to investigate the oral and dental manifestations o...

A fundamental improvement of restorative dentistry is the compensation of missing teeth by insertion of artificial dental roots allowing retention of dental prosthesis. The function of dental implants conserves a permanent perforation of the mucosa and upholds a non-physiological contact of bone with foreign material and oral micro-organisms. Occasionally head and neck cancer patients are sched...

BACKGROUND Pulp stones or denticles are frequently found in the dental pulp; there is, however, scarce evidence about this phenomenon. Regardless of the obvious endodontic problem of inhibiting access to the canals and their further treatment, they have not been given great importance. The latest experiences of scientific and practical research, including examinations of dental calcifications a...

The aim of the present study was to determine and assess the variables most involved in the etiology of a child's dental fear. The study was performed on a sample of 89 children aged from 5.5 to 12.5 years and their mothers. The sample comprised 37 children with experience of dental trauma (19 boys and 18 girls) and 52 children without experience of dental trauma (28 boys and 24 girls). Corah D...
