BACKGROUND Pulp stones (PS) are discrete calcified masses found in the dental pulp, in the pulp tissue or become attached to or embedded into the dentine. The formation of pulp stones is still something of an enigma, leading to existence of some epidemiological gaps. AIM To determine the prevalence and distribution of pulp stones in posterior tooth group by using panoramic radiograph. MATER...

• If the pulp chamber of a tooth is penetrated, either by dental caries, or by a dental drill, inflammation and eventual death of the pulp tissue usually follows. While a long interval may elapse before degeneration is complete, necrosis is an almost inevitable consequence of pulpal penetration. A current explanation in the dental literature for this phenomenon is as follows. The application of...

Current data on refinery products: LPG, mogas, naphtha, aviation fuel and Kerosene, gas/diesel oil, residual other total products, products. Countries covered: Canada, the United States, Japan, Australia, Belgium, France, Germany, Greece, Italy, Netherlands, Spain, Kingdom. Average production is thousand barrels per day. Updated a monthly basis. crude oil runs.

Abstract: This study presents the research results of effect that refining process has on porosity and mechanical properties of high pressure die castings made of AlSi12S alloy. The operation of refining was carried out in a melting furnace with the use of an FDU Mini Degasser. Mechanical properties (UTS, YS, Elongation, Brinell Hardness) were assessed on samples taken from high pressure die ca...

The results from this study showed a variety of pulpal responses to various calcium hydroxide materials when placed directly on the dental pulp. Two of the materials proved to be more successful at stimulating reparative dentin bridging and healing of the underlying pulp tissue. The remainder of the pulp capping agents were ineffective at healing the pulp and forming a reparative dentin bridge....
