The effect of calcium hydroxide on deep carious lesions.

Abstract After two years, 76 per cent of all deciduous and young permanent teeth with deep carious lesions proved to be clinically and roentgenographically sound subsequent to procedures involving application of a calcium hydroxide paste over residual caries for a six-month period, followed by complete excavation and restoration by conventional methods.

Incorporation of Tetracycline in Developing Dog Enamel and Dentin

Over the last 5 years reports have appeared in the dental literature on the appearance of yellow, brown, or gray discoloration of teeth. The patients had been exposed to extended treatment with antibiotics of the tetracycline group while these particular teeth were calcifying. There is lack of agreement in the literature between the work of Owen1 and of Harcourt, Johnson, and Storey2 concerning the localization of the drug in the enamel and dentin. Owen has reported the results of a study on a normal 8-week-old dog dosed with chlorotetracycline for 1 month daily except on Sundays. When the teeth erupted, they appeared pale yellow in daylight, and there was a yellow fluorescence under ultraviolet light. Histologic examination of ground sections with ultraviolet light showed yellow fluorescence of both enamel and dentin. Harcourt et al.2 have reported on their work with extracted teeth from five young patients known to have been extensively treated with tetracycline. They have observed (in ground sections viewed under ultraviolet light) numbers of bright goldenyellow bands in the dentin but no obvious fluorescence in the enamel. In their discussion, Harcourt, Johnson, and Storey have referred to Owen, suggesting that the fluorescence observed by him in enamel could be due to light scattering from the faces of the enamel rods and not to fluorescence of interprismatic substance. In view of these conflicting reports, it was thought that if the enamel and dentin of dog

Prosthodontic treatment of ectodermal dysplasia: A case report

Abstract Dental therapy as a phase in the treatment of ectodermal dysplasia is essential. The method of treatment of a patient with ectodermal dysplasia and associated oligodontia has been reported. As a result of prosthodontic therapy, the child has been improved esthetically, psychologically, and physiologically.
