치주과용 쿠렛과 Roto bur를 이용한 치근면 활택술을 시행한 치근의 변화 및 치근에 도포된 Tetracycline HC1의 효과에 대한 비교 연구
박해승,임성빈,정진형,Park, Hae-Seung,Lim, Sung-Bin,Chung, Chin-Hyung 대한치주과학회 1997 Journal of Periodontal & Implant Science Vol.27 No.1
Recently, alteration on chemical treatment on the root and removal of pathologic bacteria, which is the main reason for periodontal disease, by complete removal of infected cementum layer was been emphasied In this study, teeth extracted due to periodontal disease were root planed using periodontal curette and roto bur. Then they were treated with different concentration of Tetracycline HCI at different time. The state of root surface and change in the pre and post treatment was observed. The results were as follows. 1. The group treatment with periodontal curette and saline showed remaining plaque, debris and irregular surface and no dentianl tubule orifice could be seen. 2. The group treatment with periodontal curette and tetracycline HCI showed process compoed with decacified material and there was concanity seemed to be a lacunae of cementocyte. 3. The group treatment with roto bur and saline, there was no remaning plaque and partial dentinal tubule orifice could be seen but smear layer covering them.4. The group treatment with roto bur and tetracycline HCI showed various shape and size dentinal tubule orifice could be seen. From the results, roto bur showed cleaner surfaces than treatment with periodontal curette. But still smear layer existed. Thus for regeneration of periodontal tissue, chemical treatment using tetracycline HCI should follow roto bur treatment. And it is considered that the treatment time is more important than the concentration of tetracycline HCl.

There are various type of maxillary cyst. We treated a one case of aneurysmal bone cyst and two cases of dentigerous cyst of maxilla. Aneuryemal bone cyst is still an uncommon jaw lesion and is regarded as a nonneoplastic lesion consisting of cystic lesion consisting of cystic cavities with non-endothelial-lined space. Although its pathogenesis is controversial, radiographic and histologic feature is characteristic. In this case, a cystic lesion which was clinically diagnosed as a traumatic bone cyst but postoperative biopsy showed as an aneurysmal bonw cyst was developed around the apices of left central incisor and lateral incisor of maxilla, and its cause is suggested to be a trauma. Dentigerous cyst is fomed in relationship to a normal permanent tooth, but rarely it may be associated with a supernumerary tooth. In this case, a large dentigerous cyst developed around the impacted maxillary third molar encroached upon maxillary sinus and almost entirely obliterated it. One case of dentigerous cyst was found around the maxillary supernumerary impacted tooth which was located beneath the apices of left central incisor and lateral incisor. Under the local anesthesia, an aneurysmal bone cyst was thoroughly curetted and primary closure was performed. Under the general anesthesia, a dentigerous cyst which was developed maxillary third molar was enucleated with a combination of Caldwell-Luc operation and the other was enucleated with primary closure. Post-operative follow-up check revealed a good prognosis.

顔面部에 發生한 Angiolymphoid hyperplasa with eosinophilia(Kimura s disease)의 治驗例
Woong Chul Ha(河雄喆),Young Hwan Yang(梁榮桓),Hae Seung Park(朴海昇),Chong Ha Kim(金宗河) 대한구강악안면외과학회 1981 대한구강악안면외과학회지 Vol.7 No.1
Angiolymphoid hyperplasia with eosinophilia (Kimura s disease) primarily affects the skin of the head and neck and the oral mucosa. While the clinical picture is nonspecific, the variable microscopic tissue pattern often is diagnostic. The etiology is unknown, and treatment is unpredictable. A case is presented in which Kimura s disease was not suspected clinically prior to biopsy. At its early stage, the main findings consist of active vascular proliferation with plump endothelial cells and varying degrees of lymphocytic, histiocytic, and eosinophilic infiltration. The lesion at its later stage features hyperplastic blood vessels with inconspicuous endothelial cells, well-formed lymphoid follicles, and varying degrees of lymphocytic and eosinophilic infiltration. Blood eosinophilia is frequently seen.
