The economic health of dentistry: past, present, and future.

Important changes in dentistry during the past two decades include a declining caries incidence, an increase in the number of dentists, greater competition for patients, and the spread of retail dentistry and alternative plans for financing and delivering dental services. Dire predictions about the effects of these changes often have not been based on facts. This article uses available data to examine the profession's economic prospects.

Capitation and fee-for-service dental benefit plans: economic incentives, utilization, and service-mix.

Insurance carriers, corporations, and labor groups are actively developing and marketing dental capitation benefit plans. Incentives to both dentists and patients in these plans differ from those in the traditional fee-for-service system used with conventional benefit plans. This paper describes the likely effects of these incentive differences on utilization and service-mix patterns in both systems. Data for a large (approximately 10,000), homogenous group of subscribers are presented and discussed. Faced with a dual option, at no cost to the employee, 60% of the subscribers chose the fee-for-service plan, and 40% chose the capitation plan. Observed differences in the utilization and mix of services between the two plans cannot be explained solely in terms of dentists' responses. Employee response to altered economic incentives appears to be strong.

A radiographic study of tongue posture at rest and during the phonation of /s/ in class III malocclusion.

In this investigation a group of individuals with Angle Class III malocclusions were studied radiographically to determine their tongue posture at rest and during phonation of /s/. Their speech and hearing was also evaluated. All of the subjects had normal hearing, while eleven of the twelve in the group showed some degree of sibilant distortion. At rest, these Class III subjects demonstrated a tongue posture that was lower than normal and more retruded. During the phonation of /s/ these individuals also demonstrated retrusion of the tongue in an apparent attempt to achieve a normal relationship of the tongue tip to the maxillary anterior teeth, an increased amount of mandibular depression, and a greater than normal distance between the tongue tip and the mandibular anterior teeth. Despite the compensatory movements exhibited by these individuals with Class III malocclusions, normal /s/ production was found in only one of the twelve subjects studied. This is in contrast to the successful compensations that result in normal /s/ production seen in a great number of individuals with a Class III, Division 1 malocclusion, as demonstrated by Subtelny, Mestre and Subtelny.
