Progressive hemifacial atrophy (Parry-Romberg syndrome) is a slowly progressing facial atrophy of subcutaneous fat and the wasting of associated skin, cartilage, and bone. This disorder includes an active progressive phase (2 to 10 years) followed by a burning out of the atrophic process with subsequent stability. This article presents a review of the(More)
PURPOSE The purpose of this descriptive clinical study was to determine the prevalence rates of taurodontism and learning disabilities in a sample of patients with Klinefelter syndrome. METHODS Questionnaires and dental radiographs of Klinefelter syndrome patients were obtained and analyzed using previously published methods. Prevalence rates were(More)
Microleakage presents a major challenge to the success of all restorations placed in the oral cavity, resulting in postoperative sensitivity, pulpal irritation, and secondary caries formation. The objective of this study was to evaluate the effects of an adhesive cavity liner under amalgam restorations in primary teeth. Sixty class V amalgam restorations(More)
More than 6% of adolescent females become pregnant in the United States per year, yet there is no concise guide for their dental treatment. The principles for medical management of these patients are not unlike those used for adult females, but the higher incidence of complications coupled with social and consent issues make their overall management more(More)

A 6-year-old female presented with clinical and radiographic evidence of severe attachment loss around several primary teeth. She had no history of systemic disease, periodontal disease, or caries prior to the(More)

The authors recommended the use of an acrylic palatal button and .040 to .045 inch palatal wires as modifications to the palatal crib appliance. By enhancing the strength of the wire, and providing anterior support, these modifications can reduce the likelihood of the crib becoming embedded in the palatal soft tissues.
Simulated clinical conditions were used to test the effect of sterilization on rubber-dam clamp stiffness and dimension. Sixty Hygienic and Ivory W7 clamps were either steam or dry heat sterilized and compared to controls. Stiffness and dimensional change between Ivory clamp groups was significant (p<.0001); the sterilized clamps showed less change than the(More)
The purposes of this study were: 1) to compare silver solder joint strength using flame and electric soldering techniques, and 2) to determine the effect of tack welding and increasing metal-to-metal contact area prior to tack welding, on the tensile strength of silver solder joints. Six methods: (flame soldered; tack welded and flame soldered; increased(More)
