It is not known for certain that dental stone components influence titanium welding. In this study, we investigated metallurgical problems caused by laser welding on dental stones using wrought commercial pure (CP) titanium. A pulsed Nd:YAG laser irradiated a number of specimens' surfaces which were fixed on either a dental hard stone or a titanium plate. The metallurgical properties of the wel...

Calcifying nanoparticles (CNPs, previously called nanobacteria) are self-propagating, cultivable macromolecular complexes. Their extraordinary characteristic is that they can aggregate carbonate apatite on their envelope from soluble calcium and phosphorus at physiologic concentrations and display cytotoxic effects on murine and human fibroblast cell lines. The question arises whether CNPs cont...

Introduction: Nanobacteria have been implicated in the formation of pathogenic calcifications e.g. kidney stones, arterial plaque, calcified cardiac valves, dental pulp stone, etc. It has been hypothesized that nanobacteria may be present in dental calculus which has a similar mineralization formation process and that nanobacteria may play an efficient role in the calcification of dental calcul...
