Because of the dental profession's increased utilization of light-cured restorative materials, there has been a corresponding increase in research into the light sources used to initiate polymerization. The argon laser is one promising source, as the wavelength of light emitted by this laser is optimal for the initiation of polymerization of composite resins. The literature reflects a strong di...

Background Hypochlorite solution is widely used in dental practice during root canal treatment. Although it is generally regarded as being very safe, potentially severe complications can occur when it comes into contact with soft tissue especially due to its cytotoxic features. Objective The aim of our paper is to present a case of damage of oral mucosa because of leakage of 3% hypochlorite thr...

In our original paper (Wiseman & Milton, 1999), we described a number of potential information leakage pathways in Experiment One of the SAIC remote viewing program. In this paper, we counter May’s assertion that the proposed leakage paths could not have accounted for the observed difference between performance in the static-target and dynamic target conditions and refute May’s claim that there...

micro-leakage, one of the major reasons for recurrent decays, may lead to uncontrollable flow of liquids, pulp inflammation and peri-apical pathology. the purpose of this in vitro study was to evaluate micro-leakage of pit and fissure sealants after using three different pit and fissure preparation techniques: 1) acid etching, 2) fissure enameloplasty and acid etching, and 3) air abrasion and a...

Correlated sources are present in communication systems where protocols ensure that there is some predetermined information for sources. Here correlated sources across an eavesdropped channel that incorporate a heterogeneous encoding scheme and their effect on the information leakage when some channel information and a source have been wiretapped is investigated. The information leakage bounds ...

The objective of the research was to determine effectiveness obturation root canals and crown part teeth, identify most important factors influencing its results, based on X-ray examination.
 Materials methods: study conducted at Dental Center (University Clinic, Ivano-Frankivsk National Medical University). Evaluation 140 orthopantomograms, computed tomograms digital intraoral images pati...
