Legal implications of OSHA and CDC regulations.

The epidemic of acquired immunodeficiency syndrome has initiated a number of regulations, at both the federal and state level, that impact directly on the practice of dentistry. During the past 5 to 6 years, guidelines have been published that specifically and generally state those procedures which should be implemented in the dental practice with regard to infectious disease control. However, confusion remains regarding these procedural guidelines and the differences that exist between municipal, state, and federal regulations. The ensuing discussion (1) reviews the historical background of the guidelines, (2) reflects on the current Occupational Safety and Health Administration guidelines as they relate to the dental practice, (3) summarizes the role of the regulatory agencies, (4) discusses federal and state statutes that have impact on the dental practitioner, and (5) describes the possible legal implications that these regulations may have on the dental practice.

A comparison of glazing materials for composite restorations.

Composite restorations containing quartz fillers have shown persistent roughness after finishing which contributes to marginal discoloration and staining. Resin finish coatings have been used to attempt to overcome this problem. This study was designed to compare the durability of two resin coating materials used on two brands of composite restorative materials. Results showed that composites glazed with resin coating finishes at placement maintained their luster, color match, and surface smoothness significantly better after one year than composites that were not coated. After a year it was concluded that composites on which the resin coating is intact maintain their color match, luster, and smoothness significantly better than uncoated composite restorations.

Effect of glutaraldehyde-based cold sterilization solutions on light transmission of single-use, plastic light-curing tips.

Previous research has demonstrated that autoclaving of conventional curing tips results in the build-up of an opaque scale on the curing tips ends, greatly reducing light intensity output. Cold sterilization of conventional light-curing tips in most glutaraldehyde-based solutions did not damage the tip or decrease light-transmission quality. However, the specific brand of cold sterilant was found to be of importance, as one specific product was shown to decrease light-tip intensity values irreversibly, even after subsequent tip polishing. A decrease in light intensity output from the curing source significantly affects polymer cure and the biological properties of the restorative material.
