Light-cured resin for post patterns.

A method of using light-cured acrylic resin as an alternative to the use of chemically-cured acrylic resins with elastomeric impressions for direct post patterns is presented. The GC Unifast LC acrylic resin is a powder/liquid type resin cured by exposure to visible light. The polymerization process has four stages before final curing: slurry, stringy, dough-like (plastic), and rubber-like (elastic). Advantages over current direct and indirect procedures include ease of manipulation of the material and no change in laboratory handling procedures. While in the dough-like state, the material can be contoured. In the rubber-like state, it is flexible to disengage from minor undercut areas.

Removable partial overdentures. Clinical considerations.

Removable partial overdentures have the potential for salvaging teeth with poor prognoses and using them for prosthesis support and retention. Careful case selection and creative treatment planning can lead to aesthetic, well-supported restorations for a variety of patients with compromised dentitions.

Endodontic considerations in restoration of partial overdenture abutments.

Overdenture abutment teeth often require endodontic treatment. Various factors, such as status of the pulp, periodontal state of the tooth, and the sequence of overdenture treatment, influence endodontic management of the patient. After completion of endodontic treatment, the coronal part of the root filling is removed, leaving an adequate amount of the root filling in the apical part of the root canal undisturbed. The abutment tooth is then permanently restored with a filling material, or is prepared for a cast restoration.

Clinical and microbiological effects of daily brushing with either NaF or SnF2 gels in subjects with fixed or removable dental prostheses.

61 adults, with fixed or removable dental protheses, completed a 6-month double-blind trial comparing the clinical and microbial effects of brushing twice daily with either 0.22% NaF or 0.4% SnF2. Those subjects brushing with SnF2 had less gingivitis and fewer bleeding sites for both "total teeth" and "abutment teeth". Plaque scores between groups were only statistically different for the "abutment teeth". The microbial parameters, salivary S. mutans and subgingival plaque total CFU, were significantly reduced in the SnF2 group. In both treatment groups, there was a reduction over the course of the study in the number of subjects with recoverable A. actinomycetemcomitans and black pigmented bacteroides, yet there was no difference between groups.

The quality of restorative dental care.

This study investigated the quality of restorative care in a group of health center employees. With limitations in sample size, representativeness of the sample, and methods of measuring quality clearly recognized, the results of the study suggest that significant improvements in the quality of amalgams, synthetic restorations, crowns, fixed partial denture abutments, and pontics will probably require advances in the science and technology of dentistry and modifications in the present system for delivering dental care. The impact of a quality review system is unlikely to affect the care provided by the majority of dentists. Quality review should play a role in monitoring the services fo the small percentage of dentists whose care is very inadequate. Admittedly, these conclusions are speculative and are not based on a large body of experimental information. Nevertheless, the evidence that is available is suggestive, and the development of a national policy to monitor the quality of dental care must consider what can be reasonably achieved with a quality assurance system.
