What is Effect of Hydroxylapatite Particles During Healing of Experimental Furcation Involvement in Beagle Dogs. about?

The present study was performed to evaluate the effects of hydroxylapatite (HAP) on tissue regeneration in various types of furcation involvement. Upper premolar tooth sites of 9 beagle dogs (3-6 years old) were used. HAP particles were implanted into three types of furcation defects: Class III lesion (by Glickman) in 2nd premolar sites, artificially caused by intrafurcal suturing or spontaneously developed about 3 months after extraction of the 1st premolar; Class IV lesion in 4th premolar sites artificially produced 2 months before implantation; and through-and-through furcal bony defects in 3rd premolar sites at the time of HAP implantation. Macroscopic, radiographic and microscopical investigations of the postoperative status were carried out at intervals of 1, 2, 3 and 6 months. The appearance of the gingiva in bony defect sites was almost the same as that in the presurgical status 2 weeks after implantation, although gingival inflammation was persistent in Class III and IV lesions. Most particles in Class III and IV lesions exfoliated until 2 weeks after implantation, and the junctional space between recipient bone and particles could 本 論文 の要 旨 は, 第30回 秋季 日本歯 周 病 学 会総 会 (1987
