Bioelectric stimulation and residual ridge resorption.

The use of exogenous pulsed electromagnetic fields (PEMF) to stimulate the healing of nonunions and other long bone defects is common in medicine. This investigation used the dog model and image analysis of standardized radiographs to assess loss of residual ridge height following extractions. It demonstrates the effectiveness of intermittent PEMF to reduce the rate of residual ridge resorption. It further suggests there may be a causal relationship between residual ridge resorption and the alteration of endogenous bioelectric signals caused by the loss of teeth.

Young children and television: the retention of emotional reactions.

In 6 experiments, we examined preschoolers' ability to interpret or remember the affective reactions of television characters. In 2 studies, children viewed a "Sesame Street" or "Cosby Show" segment, and then retold the story. In both, mention of the protagonists' affective states was low, with less than 1% of the reactions recalled. In 3 experiments (using muppet, cartoon, or human portrayals), we examined whether this low retention was due to an inability to interpret reactions, identify their emotional labels, or remember them across a short period. For muppet and cartoon shows, children accurately recognized labels for reactions immediately after portrayal, but showed significant reductions in recognition memory by the end of the show. For human portrayals, subjects showed accurate recognition immediately after presentation, as well as after the show. In a final experiment, free descriptions of the reactions were assessed. Correct description was significantly higher for basic emotions than complex emotions.

Custom lip shield for chronic actinic cheilitis.

Chronic actinic cheilitis is a premalignant lesion related to excessive exposure to the sun. Those with fair complexions and blond hair, and those who work outside are susceptible to this disease. This article describes the fabrication of a custom lip shield to protect the lower lip from the sun in highly susceptible individuals.

Interim complete immediate dentures for a patient wearing removable partial dentures.

This article describes a technique used for fabricating temporary (interim) complete dentures for a patient who had been wearing removable partial dentures and whose remaining teeth were to be extracted. Rather than attempt to incorporate the existing removable partial dentures into the interim complete dentures, the dentist used the existing dentures to fabricate acrylic resin teeth for the interim prosthesis.

A back-action amalgam carrier.

A method has been presented for alteration of a conventional lever-type amalgam carrier for use in placement of amalgam in difficult-to-reach distobuccal and distolingual preparations. The few minutes required to alter one of these instruments will be more than repaid in time saved while attempting to place amalgam with a conventional carrier or cotton pliers. It is hoped that in the future one of the manufacturers of the conventional-type carriers will add this altered instrument to their product line.
