BACKGROUND Bubbles and voids on the occlusal surface impede the actual intercuspation and pre-impression preparation aims to reduce the incidence of air bubbles and voids as well as influences the quality of occlusal reproduction and actual clinical intercuspation in the articulator. The study was undertaken to determine the influence of different pre-impression preparation procedures of antago...

OBJECTIVE The research sought to ascertain medical and dental libraries' collection development policies, evaluation methods, purchase decisions, and issues that relate to print and electronic United States Medical Licensing Examination (USMLE) and National Board Dental Examination (NBDE) preparation materials. METHODS The investigators surveyed librarians supporting American Association of M...

For prospective motion correction in ultrahigh-field magnetic resonance imaging, optical tracking is employed by fixating a tailored dental splint on the subject’s upper jaw. However, producing such dental splints is cumbersome and exposes subjects to significant discomfort due to the required dental cast preparation. To catalyze the production of these custom-made splints, we propose a semi-au...

AIM To analyze the influence of cavity design preparation on stress values in three-dimensional (3D) solid model of maxillary premolar restored with resin composite. METHODS 3D solid model of maxillary second premolar was designed using computed-tomography (CT) data. Based on a factorial experiment, 9 different mesio-occlusal-distal (MOD) cavity designs were simulated, with three cavity wall ...

IMPORTANCE The relatively high and possibly rising incidence of mouth squamous cell carcinoma in nonsmokers, especially women, without obvious cause has been noted by previous authors. Is chronic dental trauma and irritation a carcinogen, and what is its importance compared with human papillomavirus (HPV) oropharyngeal cancer in nonsmokers? OBJECTIVE To determine whether oral cavity cancers o...

background: obtaining optimal marginal adaption with prefabricated stainless steel crowns (sscs) is diffi cult, especially after removing dental caries or defects in cervical areas. this situation requires the use of an ssc after tooth reconstruction. this study evaluated microleakage and material loss with fi ve restorative materials at ssc margins. materials and methods: one hundred and twent...

BACKGROUND AND OBJECTIVES The aim of the study was to determine the effect of two access cavity designs on the peri-cervical dentin thickness before and after instrumentation using cone beam computed tomography (CBCT). MATERIALS AND METHODS Sixty mandibular anterior teeth were divided into two groups of thirty teeth each: Group I: conventional access cavity preparation, where access was prepa...
