Reliability and validity of a questionnaire for self-assessment of complete dentures.

Background: Demand for complete denture treatment is expected to rise over several decades. However, to date, no questionnaire on complete dentures, as evaluated by edentulous patients, has been shown to be reliable and valid. This study sought to assess the reliability and validity of Patient's Denture Assessment (PDA), which provides a multidimensional evaluation of dentures among edentulous patients.

Reliability and validity of a Japanese version of the Oral Health Impact Profile for edentulous subjects.

Objective: To evaluate the reliability and validity of the Japanese version of the Oral Health Impact Profile for edentulous (OHIP-EDENT-J) patients.

Background: Oral Health Impact Profile for edentulous is an appropriate instrument for assessing the Quality of life (QOL) in edentulous patients. However, the reliability and validity of the Japanese version had not been evaluated.

Influence of palatal coverage on oral function - oral stereognostic ability and masticatory efficiency.

Purpose: Oral sensorimotor function performs an important role in mastication. This study investigated the influence of wearing experimental palatal plates on masticatory efficiency and oral stereognostic ability (OSA), and the relationship between these two functions.

Methods: Fifteen young adults with healthy dentitions (mean age, 26.

Evaluation of denture retention and ease of removal from oral mucosa on a new gel-type denture adhesive.

Purpose: The purpose of this study was to evaluate the effect of a new gel-type denture adhesive on denture retention and ease of removal from the oral mucosa after use.

Methods: Eleven complete denture wearing patients (3 males and 8 females; age range, 58-84 years; mean age, 73.7 years) with compromised maxillary denture-bearing tissues were included in the study.

Palatal coverage disturbance in masticatory function.

Oral sensorimotor function is essential for mastication. We hypothesized that palatal coverage would disturb mastication and sensorimotor function. Masticatory efficiency, which was expressed by the declination rate of particle size, and oral stereognosis ability (OSA) were measured for 20 dentate subjects.
