Soft tissue profile: a survey of African-American preference.

Soft tissue profile is a critical area of interest in the development of an orthodontic treatment plan. This study was designed to elicit the current soft tissue profile preference of African-American respondents. Results indicate that: (1) African-American male and female subjects prefer relatively flat profiles, with varied fullness of the lips. (2) African-American male and female subjects prefer the male subjects to have more protrusive profiles than the female subjects. (3) Respondents do not always correctly select their own profile type. (4) More than a third of the respondents desire a change in their own profile.

Endodontic considerations in the design of acid-etched anterior splints for patients with reduced periodontal support.

A modification of existing designs for resin-bonded retainers has been introduced. This new design is appropriate for the extracoronal splinting of anterior teeth with reduced periodontal support. The design of the splint will accommodate the increased risk of these teeth for endodontic failure. The versatility and advantages of this design have been presented and compared with other anterior splinting techniques. At present, there appears to be no clinically significant difference in the retentiveness of perforated and nonperforated etched metal retainers.

Applying an evaluation model to a dental public health program.

The applicability of an evaluation model applied to an urban dental public health program was assessed. The model required the specification of objectives and focuses on the accomplishment of these objectives and the associated costs. This model is primarily a goal model as contrasted with a system model; thus, the focus was on goal accomplishment. The model was simple to use and provided detailed evaluation information for use by administrators.

Reliability of an intraoral camera: utility for clinical dentistry and research.

Photographic images can be reliable and efficient sources of data in dentistry. Many variables can be investigated from single exposures. This study was undertaken to test the reliability of an intraoral graphic instrument--the Orthoscan camera. The utility of this instrument in clinical orthodontics has been described, but the research potential has yet to be investigated. Upper and lower dental arches of fifteen patients were photographed intraorally. Alginate impressions of the arches were taken immediately afterward. Identical intertooth distances were located (1) on the intraoral photographs, (2) on the photographs of the dental casts, and (3) on the dental casts themselves. Univariate and multivariate analyses were used to assess measurement error in these replicate measurements. The camera was found to be a highly reliable instrument. The images are flat and free of distortion, with a one-to-one size relationship. The camera is quite suitable for precise scientific investigations, and the data are acceptable for valid interobserver and interpopulation comparisons.

An endodontic-orthodontic technique for esthetic stabilization of externally resorbed teeth.

Previous studies reveal that external root resorption is often coincident with orthodontic therapy. Some investigators have reported that root resorption ceases when orthodontic therapy is terminated. However, this is not always the case. The purpose of this article is to present an 11-year history of an unusual case in which root-resorptive processes continued for 3 years after orthodontic treatment had been discontinued. The article also describes and discusses a combined endodontic-orthodontic approach to halt external root resorption and stabilize mobile maxillary anterior teeth. Calcium hydroxide therapy was instituted to inhibit inflammatory apical root resorption. A rectangular orthodontic wire was adapted and inserted intracoronally to splint the teeth esthetically. The advantages and disadvantages of this intracoronal splinting technique are compared with other extracoronal splinting methods. Examination of one-year recall radiographs suggested inhibition of the root resorption. Masticatory function was restored for the patient. Considerations for monitoring patients with this problem are discussed.
