    Objective: To assess intended refusal of recent graduates from three Arab dental schools to treat HIV + patients and factors associated with this intention.

    Materials And Methods: In 2015, convenience samples of recent dental graduates were included from Libya, Egypt and the United Arab Emirates. Participants responded to a questionnaire assessing personal background, knowledge of oral manifestations and fluids transmitting HIV, perceived adequacy of training and self-efficacy to manage blood exposures, attitude to risk of infection, moral beliefs and willingness to treat HIV + patients.

    a Department of Pediatric Dentistry , Yonsei University Wonju College of Medicine , Wonju-si , Korea.
    Objective: Supernumerary teeth, a term describing a condition where patients have an abnormally large number of teeth, can be associated with non-syndromic or syndromic phenotypes. PDGFRs are cell surface tyrosine kinase receptors, and are involved in several aspects of tooth development. The purpose of this study was to identify causative genes of familial supernumerary teeth and the molecular pathogenesis of tooth number abnormalities through genetic analysis of a family that showed supernumerary premolars in two successive generations.

    Assessment of lingual nerve functions after smoking cessation.
    Acta Odontol Scand 2017 Jul 3;75(5):338-344. Epub 2017 Apr 3.
    d Department of Conservative Dentistry, Periodontology and Preventive Dentistry , University Hospital Aachen , Aachen , Germany.
    Objective: Cigarette smoking is associated with a variety of oral diseases. A previous study showed a reduction of thermal sensitivity in the innervation area of the lingual nerve in smokers possibly caused by a degeneration of thermosensitive receptors as a consequence of smoking. The current study investigates somatosensory changes in ex-smokers. Read More
