AIM To determine the incidence of aspiration and ingestion of endodontic instruments in France during root canal treatment without using rubber dam. METHODOLOGY Data was provided by two insurance companies representing 24,651 French general dentists over 11 years. The type and number of accidents per year, the number of dental items involved and the percentage of occurrence of either aspirati...

Differences in mechanical properties between endodontic instruments might be related to the chemical composition, phase constitution, or fabrication process of nickel–titanium (NiTi) endodontic instruments. An awareness and knowledge of the mechanical properties of NiTi endodontic files and their association with the metallurgical properties is useful for clinicians to understand the behavior o...

AIM To determine whether the following can be sterilized by autoclaving - endodontic sponges, rotary nickel-titanium (NiTi) instruments within endodontic sponges, and rotary NiTi instruments with rubber stoppers. METHODOLOGY Sixty-four samples of eight different endodontic sponges (n = 512) were placed into brain heart infusion broth (BHI) for 72 h. An aliquot of this was then spread onto hor...

introduction: root canal preparation techniques may cause postoperative pain. the aim of the present study was to compare the intensity of postoperative pain after endodontic treatment using hand files, single file rotary (oneshape), and single file reciprocating (reciproc) systems. methods and materials: in this single-blind, parallel-grouped randomized clinical trial a total of 150 healthy pa...

BACKGROUND AND AIM: This study was carried out to compare three different ultrasonic cleaner devices in the cleaning process of endodontic instruments by scanning electron microscope (SEM). METHODS: In this study, 120 unused brand new hand and rotary instruments were examined after removing from the sealed package. The instruments were randomly divided into six groups of 20 rotary or hand files...

There is current concern in the UK over the possible transmission of prions via contaminated surgical instruments. Some dental instruments (endodontic files) raise particular concerns by virtue of their intimate contact with terminal branches of the trigeminal nerve. A visual assessment using a dissecting light microscope and scanning electron microscopy of endodontic files after clinical use a...

This study evaluated the perceptions of Brazilian undergraduate dental students about the endodontic treatments performed using NiTi rotary instruments and hand stainless steel. Data were collected using a questionnaire administered to undergraduate dental students enrolled in endodontic disciplines. The students were divided into 3 groups: G1, students who had treated straight canals with SS h...

OBJECTIVE The purpose of study is to find the prevalence of usage of different advanced endodontic instruments and techniques in pediatric dentistry. MATERIALS AND METHODS A self-administered, structured questionnaire written in English validated through a pretested survey was randomly mailed to the postgraduate students in different dental colleges. A total of 182 of the complete filled ques...

Background and Aims: The aims of this article were to assess the current endodontic practice in Turkey and to find out the opinions of practitioners on their level of practice and training needs. Subjects and Methods: A questionnaire dealing with current endodontic practice was prepared. A total of 650 practitioners from Turkey were randomly chosen and the questionnaires were sent to their e-ma...
