Statement Of Problem: The prevalent use of computer-aided design and computer-aided manufacturing (CAD-CAM) for tooth-colored ceramic materials has led to several case reports and retrospective clinical studies of surveyed crowns used to support removable partial dentures. How the specific contour of a cingulum rest seat affects the fracture resistance of these CAD-CAM tooth-colored materials is unknown.

Purpose: The purpose of this in vitro study was to compare the fracture resistance of monolithic CAD-CAM tooth-colored mandibular canine-surveyed ceramic crowns with cingulum rest seats of different designs. Read More

Purpose: To ascertain whether in the presence of a previously endodontically treated tooth with periapical pathology and/or symptoms and an uncertain prognosis, it is better to endodontically retreat it or to replace the tooth with a single-implant-supported crown.

Materials And Methods: Twenty patients requiring the treatment of a previously endodontically treated tooth, with periapical pathology and/or symptoms of endodontic origin and an uncertain prognosis, as judged by the recruiting investigator, were randomly allocated to endodontic retreatment (Endo group, 10 patients) or tooth extraction and replacement with an implant-supported crown (Implant group, 10 patients) according to a parallel-group design at a single centre. Patients were followed to 3 years after completion of the treatment. Read More

Background: Bulimia nervosa is an eating disorder resulting in an intended weight loss due to decreased food intake, induced vomiting, or hyperactivity, and is observed frequently between 12 and 25 years of age. One of the complications is early tooth loss. Moreover, since bulimia nervosa patients suffer from increased atrophy of the alveolar processes, oral rehabilitation even with short dental implants may be impossible. Read More

The Spanish term grima refers to the aversive emotional experience typically evoked when one hears, for example, a scratch upon a chalkboard. Whereas Spanish speakers can distinguish between the concepts of grima and disgust, English and German speakers lack a specific word for this experience and typically label grima as disgust. In the present research, we tested the degree of differentiation between the two aversive experiences in Spanish speakers. Read More

Dental root fractures are rarely documented in past human populations, but when they are observed, diagnosing ante-mortem events as causal factors can be difficult due to postmortem alteration. Can high resolution X-ray computed tomography (CT) improve our ability to diagnose if a dental fracture was caused ante- or post-mortem? To test this, a case study of two individuals with previously diagnosed dental root fractures were re-examined with high resolution CT to confirm or refute the original diagnoses. For individual 4170, use of high resolution CT supported the original diagnosis of an ante-mortem root fracture on the right mandibular central incisor that was made based on planar X-ray. Read More
