Enamel microabrasion: a new approach.

Enamel microabrasion is a proven method of removing superficial intrinsic enamel discoloration defects. The method is safe, easily performed, and causes no discomfort for the patient. A new commercially available microabrasion system has been introduced by Ultradent Products Inc. In addition, a new tooth isolation material is available, along with a visible light-activated in-office hydrogen peroxide solution. This article describes these new products and documents tooth-color correction for two young patients using this new tooth-color correction approach.

Dental students' attitude to gender roles.

This investigation assessed attitudes held by United States women and men dental students toward professional and sex role concepts. The concepts included: female dental student, male dental student, dentist, adult woman, adult man, wife and husband. These attitudes were evaluated and compared in the context of the students' current and future professional roles and their sex roles. Although there were several differences in attitudes between the two subject groups, the results suggest that the women and men dental students viewed their various roles as consistent with one another. It is particularly important to note that the women dental student is viewed by both gender groups as having professional and sex roles which do not conflict.

Preformed resin-veneered stainless steel crowns for restoration of primary incisors.

Stainless steel crown forms with bonded resin veneers for primary incisors are commercially available to dentists. This type of preveneered crown was developed to serve as a convenient, durable, reliable, and esthetic solution to the difficult challenge of restoring severely carious primary incisors. This article describes preveneered crowns, reviews their advantages and disadvantages, and details a technique for placement of such restorations.

Bilateral fusion and gemination: a literature analysis and case report.

The dental literature concerning the bilateral presentation of fusion and gemination is reviewed and analyzed. Tables are presented to show the prevalence and distribution of these anomalies in both the primary and permanent dentitions. In addition, the first prevalence statistics for the bilateral occurrence of fusion and gemination in the primary and permanent dentitions are determined. The first case of bilateral fusion of mandibular primary incisors to be reported in 13 years is presented. The presence of all four succedaneous incisors and the diagnosis of bilateral fusion are confirmed radiographically. The developmental concerns and possible sequelae of bilateral fusion and gemination are also discussed.

Vitremer restorative cement for children: three clinicians' observations in three pediatric dental practices.

BACKGROUND: The authors retrospectively evaluated the clinical performance of a resin-modified glass ionomer cement as a Class I, Class II, Class III, and Class V restorative material in primary teeth. METHODS: Three hundred and six patients that had received 864 resin-modified glass ionomer restorations, which had been in the mouth for a minimum of three years, were included in this evaluation. RESULTS: The results demonstrated an overall 93.4 percent restoration success rate, Class I restorations presenting a 92.6 percent success. Class II restorations presenting a 93.4 percent success, Class III restorations presenting a 100 percent success and Class V restorations presenting a 98 percent success, respectively. CONCLUSIONS: The resin-modified glass ionomer cement functioned well as a Class I, Class II, Class III, and Class V restorative material in the primary dentition. CLINICAL IMPLICATIONS: Resin-modified glass ionomer cement restorative material functions well for Class I, Class II, Class III, and Class V restorations in primary teeth.

Local anesthetic mortality: report of case.

The case of a healthy five-year-old, thirty-six pound female patient scheduled for multiple extractions is reported. The child received a total dose of 270 mg of mepivacaine, instead of the correct dose of 72 mg, which resulted in multiple seizures, hospital admission, pneumonia, and death caused by anoxic brain injury secondary to cardiopulmonary arrest following the overdose.

Clean vs sterile technique for pediatric dental patients in the operating room.

Recommendations on the need for clean or sterile technique have been made based on personal experience. This retrospective analysis of 100 children and adolescents who received dental treatment in the operating room shows no statistical difference in morbidity or postoperative complications between patients treated with the different techniques.

Troubleshooting for the laminate veneer restoration.

The laminate veneer restoration may present problems for the practitioner when stain lines occur at the incisal edge, after a period of use. This paper describes a successful conservative technique that avoids compromising the veneer by applying a heating source to a bleaching medium on the tooth.

Heat adaptation for the laminate veneer: a new technique.

A new method of heat adaptation for the Mastique laminate veneer restoration has been described. This technique is substantially quicker and easier to employ than the old method of boiling. It also has the advantage of permitting greater control since each veneer is individually molded. While this technique has not been attempted with veneers made by other manufacturers, it appears that the basic principles will, nonetheless, apply.
