statement of the problem: exposure to patients’ blood and body fluids would prone the dental students to the risk of blood borne infections. several studies have shown a high prevalence of these exposures in dental settings particularly in developing countries. however, few studies have evaluated the epidemiology of these exposures in dental students in iran. purpose: to assess the epidemiology...

T HE USE of conventional or increased handpiece operating speeds for the shaping of cavities in human teeth results in vibration, temperature changes, and other physical factors within the calcified tooth tissue and its organic matrix. The airbrasive and ultrasonic methods of cutting tooth tissue appear to create similar forces. The effects of these trauma may or may not be significant to the l...

OBJECTIVE The aim of this study was to compare the cyclic fatigue resistance of two nickel-titanium (NiTi) endodontic instruments from ProTaper and GT series X files. STUDY DESIGN Cyclic fatigue test was realized with instruments from ProTaper: F1 and F3 (Denstply Maillefer, Ballaigues, Switzerland) and GT-X: 20.06 and 30.08 (Dentsply Tulsa Dental, Tulsa, Oklahoma, United States of America). ...

The implementation and execution of effective infection control protocols among all health care communities cannot be overstressed. Infection control becomes even more significant in dentistry as more microorganisms are found in the oral cavity than in any about half as infectious as blood, and the most likely modes of transmission in dental offices are through puncture wounds, skin abrasions, ...

Root canal stripping is defined as an oblong, vertical perforation that appears especially in the middle section of curved root canals during endodontic treatments with nickel-titanium (Ni-Ti) instruments. Its occurrence may drastically affect the outcome of the treatment, transforming a common otherwise efficient endodontic procedure into a complication such as tooth extraction. In order to di...

A cohort of dental students (N=28) at the University of Manitoba was followed throughout their entire dental education program to explore changes in their perceptions of the learning environment over time. Aspects of the students'psychological functioning, including common psychological symptoms, self-esteem, and coping strategies, were also evaluated to assess changes in these factors over tim...

one of the complications during a routine dental implant placement is accidental ingestion of the implant instruments, which can happen when proper precautions are not taken. appropriate radiographs should be taken to locate the correct position of foreign body; usually the foreign body passes asymptomatically from gastrointestinal tract but sometimes it may lead to intestinal obstruction, perf...

BACKGROUND Although the contamination of the dental environment and personnel through aerosol contamination is a definite source of cross contamination; there is little data on the microbial involvement of the dental environment. MATERIALS AND METHODS A total of 100 samples were taken from various inanimate surfaces in the clinical dental setting were collected aseptically by rotating sterile...
