Content and solubility of sodium in denture adhesives.

The objectives of this study were to determine the content and solubility of sodium in denture adhesives, and to ascertain relationships between these values. Nine powder and 10 cream denture adhesives were assayed for sodium by spectrophotometry. The range of dry weight sodium content was 2.4 gm/100 gm to 6 gm/100 gm. The range of solubility of sodium in the denture adhesives, as determined by in vitro methods, was 0.51 gm/100 gm to 1.70 gm/100 gm. The percent of solubility of sodium was 12% to 42%. Application of the Mann-Whitney test determined that the observed differences in sodium content and percent of solubility between the groups of powder and cream adhesives were not significant (alpha 0.001). However, sodium solubility of the powder adhesives was significantly greater (alpha 0.001) than that of the cream adhesives. It has been shown that dietary sodium restriction reduces blood pressure in hypertensive patients and that a diet high in sodium chloride produces hypertension in the population predisposed to the disease. This study raises questions as to the possible effect of the sodium in denture adhesives on the hypertensive patient. We suggest the use of adhesives with a low percent of sodium solubility.

A clinical view of mandibular premolars in removable partial denture design.

Mandibular premolars are used as a model to discuss various strategies for the design of removable partial dentures. Factors that must be taken into consideration as the prosthesis is designed, such as coronal and radicular anatomy of the abutment teeth, the relationship of the abutment teeth to other teeth, and the presence of existing restorations, are also identified.

Microcomputer-aided removable partial denture design: the next evolution.

A microcomputer-based program for the design of removable partial dentures has applications in dental education and the clinical practice of dentistry. The program requires a Macintosh computer with a minimum configuration of one megabyte of random access memory and a hard disk drive with a HyperCard program. The instructional design uses an interactive, branching user interface to conduct a search of removable partial design data. The screen design is based on a dental laboratory work authorization, with graphic representations of partially edentulous dental arches and textual information that can be browsed in a nonlinear manner by the user. Approximately 160 removable partial denture designs are provided in the program, as well as the ability to modify the drawings and text to reflect various other clinical situations and to print the work authorization for submission to the dental laboratory.

Microcomputer-aided removable partial denture design.

A microcomputer-based program for the design of removable partial dentures is described that has an interactive user interface to conduct a heuristic search of removable partial denture design data and produces computer-generated design graphics. The program is useful educationally and clinically.
