AIM To evaluate the radiographic technical quality of root fillings performed by undergraduate students at a dentistry faculty in Turkey. METHODOLOGY A random sample of 2000 records of patients who received dental treatment at the Faculty of Dentistry, University of Gazi between 2000 and 2003 was investigated. The final sample consisted of 1,893(More)
The aim of this study was to compare the amount of apical extrusion during manual instrumentation and engine-driven rotary instrumentation in teeth with disrupted apical constriction. Fifty-two teeth were divided into two groups comprising 26 teeth each. Teeth in each group were further divided into two sub-groups, the apices of which were enlarged(More)
In endodontics, a laser can be used as a heat source and gutta-percha can be softened by a laser and used in the root canals. The System-B endodontic heat source unit was designed for the obturation of the root canal system with a single continuous wave of thermoplasticized gutta-percha. The aim of this study was to compare the apical leakage of lateral(More)
The main objective of this in vitro study was to evaluate the effects of the operator's experience level and pre-flaring on the accuracy of the results of three different brands of a new generation of root canal measuring devices, as well as the comparison among them. Extracted human teeth were prepared and then actual length and electronic length(More)
OBJECTIVE The objective of this study was to evaluate whether the changes in the design of the ProTaper canal instruments contribute to the shaping ability of the instrument in terms of the morphology of curved canals measured by the cross-sectional area using the Bramante method. STUDY DESIGN Ten extracted human mandibular molars with root canal(More)
AIM To present a case describing the endodontic treatment of a permanent canine with radiculomegaly and to draw the attention of the endodontic community to this rare anomaly. SUMMARY Oculo-facio-cardio-dental (OFCD) syndrome is a rare X-linked dominant syndrome characterized by canine teeth with extremely large roots (radiculomegaly), dental(More)
AIM To collect quantitative information about the numbers of odontoblast-like cells and reparative dentine thickness after direct pulp capping with platelet-rich plasma (PRP) and enamel matrix derivative (EMD). METHODOLOGY The experiment was conducted on 36 Wistar albino rats and a total of 144 incisor teeth. Calcium hydroxide, mineral trioxide aggregate,(More)
Furcal perforation is usually an undesired complication that can occur during preparation of endodontic access cavities or exploring canal orifice of multirooted teeth. Inadequacy of the repair materials has been a contributing factor to the poor outcome of repair procedures. On the basis of the recent physical and biologic property studies of the(More)
OBJECTIVE Sodium hypochlorite (NaOCl) is a common antimicrobial and tissue-dissolving irrigant. The aim of this in vitro study is to evaluate and compare dissolution capacities of sodium hypochlorite solutions after electrically activation (E-NaOCl) on bovine muscle specimens at various time periods and concentrations. MATERIALS AND METHODS Three sodium(More)
This study evaluates the amount of remaining tooth structure and possibility of producing lateral perforation following the use of different diameters of parallel-sided Parapost drills in groups of different canal curvatures (0 degrees-15 degrees, 16 degrees-25 degrees, 26 degrees <) in distal canals of first and second mandibular molar teeth. After(More)
