Delmopinol - adsorption to and absorption through the oral mucosa.

Objectives: To investigate the surface chemical changes in dynamic interactions of delmopinol on salivary films on oral mucosa in healthy participants after rinsing with an unbuffered water solution of delmopinol, and to examine the oral tissue disposition of delmopinol in rats after local administration.

Material And Methods: The contact angle technique was used to monitor the interaction of delmopinol with the salivary film coating the upper labial mucosa of 10 healthy participants through a 4 h period. The tissue disposition of C-labelled delmopinol was examined in rats by autoradiography.

Prospective observation of a new bioactive luting cement: 2-year follow-up.

Purpose: A pilot study was conducted to determine the 2-year clinical performance of a new bioactive dental cement (Ceramir C&B, formerly XeraCem) for permanent cementation.

Materials And Methods: The cement used in this study is a new formulation class, a hybrid material comprising calcium aluminate and glass ionomer. Thirty-eight crowns and fixed partial denture (FPD) abutments were cemented in 17 patients.

On the accuracy of some in vitro models for mechanical studies of maxillary removable partial dentures.

Objectives: Comparative in vitro/in vivo studies show wide differences in functional strain magnitudes and patterns of functional strain distribution in prosthetic devices. The aim of this study was to evaluate the accuracy of three in vitro models for biomechanical studies of prosthetic devices.

Methods: Strain gages were attached to the test RPDs of six subjects.

Quality of fixed prosthodontics after twenty-two years.

After an observation period of 22 years, this study was conducted to clinically examine and interview patients who in 1984 and 1989 had participated in similar investigations regarding the quality, over time. of treatments with fixed partial dentures. The patients were examined by two standardized and experienced clinicians using thc California Dental Association quality rating system, their results indicating that after 22 years the overall survival rates were 46.

The effects of fixed and removable implant-stabilised prostheses on posterior mandibular residual ridge resorption.

This study investigated the change over time in the area of the posterior mandibular residual ridge in patients wearing either i) mandibular overdentures stabilised by two implants (Brånemark System; Nobel Biocare, Göteborg, Sweden) connected by a bar, or ii) mandibular fixed cantilever prostheses stabilised on five or six implants. Proportional measurements were made in order to compare the area of the residual ridge with an area of bone uninfluenced by resorption. Measurements were made by digitising tracings of panoramic radiographs that were taken shortly after implant insertion and up to seven years later.
