Reliability and validity of the patient disability-oriented diagnostic nomenclature system for prosthetic dentistry.

Purpose: The Japan Prosthodontic Society (JPS) has proposed a new diagnostic nomenclature system (DNS), based on pathogenesis and etiology, to facilitate and improve prosthodontic treatment. This system specifies patient disability and the causative factor (i.e.

Effects of team-based learning on fixed prosthodontic education in a Japanese School of Dentistry.

The aims of this study were to evaluate the quality of team-based learning (TBL) in prosthodontics education for fourth-year dental students at Tokushima University School of Dentistry and to compare this teaching method with traditional lecture-based delivery. Participants in the study were 36 students (22 males and 14 females) who attended the TBL-style fixed prosthodontics course. Ten 60-minute classes were held.

Assessment of allergic hypersensitivity to dental materials.

Some metallic materials in dental prostheses may cause allergic hypersensitivity. Symptoms appear not only in the oral cavity, but also on hands, feet or the entire body. Release of metal ions is thought to cause the allergic reactions; micro-particles of the corrosion products of the metal and/or ionic metal hydroxides/oxides may be the allergens.

[Studies on the standardization of parameters for jaw movement analysis--6 degree-of-freedom jaw movements analysis].

Purpose: To establish standardized evaluating methods for jaw movements analysis. In this paper, we investigated evaluating parameters for 6 degree-of-freedom jaw movements data.

Methods: Recorded data of jaw border movements from 20 male adults were employed as basic samples.

[Studies on the standardization of parameters for jaw movement analysis--jaw movement analysis at the incisal point].

Purpose: To establish standardized evaluating methods for jaw movements analysis independently of the reference coordinate system. In this paper, we focused on the analysis of incisor point paths of border movements. Then we investigated parameters that are independent of the reference coordinate system and can be utilized among different systems.

Contingent electrical lip stimulation for sleep bruxism: a pilot study.

Statement Of Problem: No effective method has been found to fully control sleep bruxism, although contingent feedback methods show some promise.

Purpose: This demonstration-of-concept study evaluated the effect of contingent electrical lip stimulation on sleep bruxism.

Material And Methods: Recordings of masseter muscle activity were performed over 5 nights in 7 subjects with acknowledged bruxism and dental attrition (5 men, 2 women).
