글라스 아이오노머와 레진수복물 변연의 우식내성에 관한 비교실험연구
사우경,손일수,김용기 단국대학교 치의학연구소 1992 논문집 Vol.4 No.-
Standardized cavities were prepared on 60 permanent teeth which had been selected according to inherent fluoride ion content of enamel and several glass ionomers and composite resins were restored. After classification and deposition for 1, 2 and 3 weeks, artificial caries was made on these specimens and resulting histologic appearances and depths of the lesions were observed by a polarizing microscope. Then caries resistant effects of each materials were compared and analyzed. In groups of Ketac-Fil and Fuji Ⅱ, the depth of lesion was increased markedly as the distance had been far away from the margin of restoration materials, wherease in the control group(Silux Plus), lesion depth was deeper than the experimental group and uniform depth of lesion was made despite of the distance from the margin. Fluoride ion content released in solution was higher in Ketac-Fil, Fuji Ⅱ, Silux Plus by descending order and statistically significant difference between groups could be found.

Partial anodontia associated with Ectodermal Dysplasia, may be inherited as a sex-linked recessive characteristic. The size of the primary teeth that are present may be normal or reduced. The anterior teeth are often conical, which is one of the characteristic of oligodontia associated with an Ectodermal Dysplasia. Children with a large number of missing primary teeth can have partial dentures constructed at an early age which have been shown to improve their masticatory function and nutritional states. A ?? year-old male with Ectodermal Dysplasia showing oligodontia and a number of abnormal shaped primary teeth was treated by using anterior strip/open-faced stainless steel crowns, posterior casted metal crowns and removable acrylic partial dentures on upper/lower arches in order to rehabilitate functional and esthetic problems.
