Reduction of the initial bioburden on instruments, prior to sterilization, is believed to reduce transmission risks of iatrogenic Creutzfeldt-Jakob disease. Endodontic files are used in the preparation of root canals and are likely to have close contact and become contaminated with neural material from branches of the maxillary and mandibular cranial nerves. This study examined methods used by ...

AIM To assess levels of anxiety in children concerning different dental instruments and equipment and to relate them with parents' anxiety levels moments before the appointment. MATERIALS AND METHODS Fifty children from 4 to 12 years of age (average of 10±3.07) and their respective parents were evaluated. A facial scale was used to assess children's anxiety levels, while the Dental Anxiety Sc...

The principal objective was to measure the magnetic fields occurring in dental surgeries at simultaneous subtraction of direct ground component of the magnetic field. A specifically designed instrument with the Hall probe was used for the measurement. It consisted of two amplifiers and a low frequency filter. Its task was to measure mean square values of the field (RMS) dependent on the positio...

Over 170 million patients worldwide are chronically infected with Hepatitis C virus (HCV); making it a globally important infection. Dentists constantly handle sharp instruments infected with biological fluids and are therefore considered at high-risk of contracting HCV infection. Needle-stick injuries seem to be the most common route of exposure to blood-borne pathogens in dental practice. Mor...

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...

Introduction: Musculoskeletal disorders (MSD) are the most frequent cause of disability in the working population, exceeding accidental trauma in frequency. The risk of developing work-related upper limb disorders (WURLDs) is high among dental hygienists and the most frequently affected are elderly subjects and women. Since such disorders can have a negative effect on the working life and on th...

The Academic Motivation Scale is one of the most frequently used instruments to assess academic motivation. It relies on the self-determination theory of human motivation. However, motivation has been understudied in dental education. Therefore, to address the lack of valid instruments to assess academic motivation in dental education and contribute to future research in the field, the aim of t...

This review summarizes the available literature for both instruction and evaluation of the novice dental and dental hygiene preclinical student. Effective instruction for dental and dental hygiene instrumentation requires knowledge of motor skills theory and mechanisms of fine motor skills attainment. The novice learner requires small, explicit steps that clearly define production. Prior to any...
