This study was to analyze the changes of levels of alkaline phosphatase before and after enucleation of jaw cysts combined with bone grafting, and to evaluate biochemically the effectiveness of the early detection of bone healing and infection as a prognostic marker. Eighteen patients (13 males, 5 females) with cystic lesions of the jaws were divided into two groups. The bone graft group underwent enucleation and bone graft. The control group underwent only enucleation. Both groups were measured levels of ALP before surgery, and plus-minus 4 weeks postoperatively. The more discriminating results were obtained in the bone graft group. The results were as follows : 1. Levels of ALP after enucleation of jaw cysts were decreased in all patients with and without bone graft. 2. The bone graft group showed more marked decrease in variation of levels of ALP than the control group.(p=0.008) This should be considered as a result of increased osteoblastic activity and new bone formation. 3. Such variation could be used as a prognostic marker for bone healing after cyst operation. In the cost/benefit ratio, measurement of ALP activity could be useful as a convenient procedure in routine clinical practice.

Objective: The purpose of this study was to determine whether cyst enucleation would be done after marsupialization of large cystic lesion on the jaws or not, and if so, when it should be done. Patients & Methods: 12 patients with cystic lesion treated by marsupialization only and 10 patients with cystic lesion treated by marsupialization followed by enucleation were examined in this study. Postoperative clinical and radiographic examinations were performed at 1, 4, 7, 10, 13, 16, 19 months on 22 patients. Bone regeneration and reduction rate of the residual cystic cavities and bone density were evaluated with a analysis of digital panoramic radiographs. Also histological evaluation of the healing process was performed on 1 patient. Results: Uneventful healing and spontaneous bony filling of the residual cavities were observed in all cases. Postoperative radiographs showed that the size of the lesions was reduced for a few months, but the reduction rate of the residual cavity was minimized for 13~16 months after marsupialization. The bone density was increased 22.5 % after 19 months. Conclusion: This results suggest that the appropriate timing to perform enucleation would be 13~16 months after marsupialization. The state of healing process could be confirmed by histological examination and radiographic evaluation of bone density. Enucleation after marsupialization could be applied appropriately to reduce the periods of bone healing in large cystic lesion on the jaws.

This study evaluated the use of endoscopy to examine jaw cysts during the operation. Fifteen jaw cysts were explored with a endoscope immediately before and after enucleation. Endoscopic findings were evaluated and recorded with video tape. Before enucleation, there were many white fibrous floating materials within the cystic cavity. Cystic lining showed smooth and regular appearance with capillary network. However, there were some fibrous scar tissues and irregular architecture in preoperative infection. After enucleation, there were white shiny bony surfaces with fresh vascular network. In some cases, floating fibrous tissues remained after removal.

Bone grafts are becoming increasingly common in oral and maxillofacial surgery to improve bone healing procedures. Bovine bone as a xenograft is a representative osteoconductor and space filler; however, sometimes complications, such as infection and wound dehiscence are encountered with its use. We report the result of an eight-year follow-up of a xenograft case and processing methods of inorganic bovine bone along with a review of the literature. Xenograft ($LUBBOC^{(R)}$) was used in a cyst enucleation site of the maxilla, as a bone substitute and space filler. Inflammation and infection were defined several times as lack of osseous contact between the graft and host bone, caused by remodeling failure over an eight-year period. Pathologic findings of the xenograft revealed dead bony trabeculae with inflamed fibrous tissue and actinomycosis.

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare form arising within the jaws. PIOSCC is not related to the oral mucosa, presumably developing from remnants of the odontogenic epithelium. Because odontogenic cyst epithelium often transforms malignantly into PIOSCC, it could be misdiagnosed as odontogenic cyst based on a relatively ill-defined radiolucent lesion. Therefore, definite diagnosis is established from histological examination of biopsy samples taken during cyst enucleation in many cases. The present study is reported with a case of patient complaining of discomfort on his mandible. He was diagnosed as a putative dentigerous cyst and underwent a cyst enucleation treatment. After definite diagnosis as PIOSCC was established based on histologic findings, partial mandible resection and mandible reconstruction were performed. Up to the present, 10 months follow up of the patient showed satisfactory healing without recurrence and abnormal findings; thereby, we are reporting this case with literature review.

A dentigerous cyst is an epithelium-lined sac that surrounds the crown of an impacted, embedded, or unerupted tooth. Many surgical procedures have been described for the elimination of dentigerous cyst, but they can be devided into two basic group: enucleation and marsupialization. Marsupialization is a conservative technique which allows the reduction or elimination of a cystic lesion by making it an accessory compartment to the oral cavity and it is the best way to conserve a tooth affected by dentigerous cyst and to permit its eruption, especially in young patient. After using marsupialization to treat dentigerous cyst associated with the crown of unerupted premolar in young patient, the results were as follows: 1. Reduction of bony expansion and rapid bone regeneration without infection and recurrence were observed. 2. Normally spontaneous eruption of involved teeth were permitted, as well as loss of affected tooth was avoided. 3. Follow-up examinations revealed no complication and recurrence.

Ameloblastoma is an aggressive benign odontogenic epithelial tumour that may arise from the enamel organ, remnants of dental lamina, or the lining of an odontogenic cyst. It is usually categorized into solid or multicystic, unicystic, and peripheral types. Treatment ofameloblastomas include conservative methods such as marsupialisation, enucleation, and curettage; and radical treatments such as marginal or segmental resection. Radical treatments have resulted in lower recurrence rates; however, may also encounter esthetic, functional, and reconstructive problems. Unicystic ameloblastoma has been considered less aggressive and a lower recurrence tendency. Thus, many authors have recommended conservative treatment in cases of unicystic ameloblastoma. An 11 year-old boy presented with displaced second and third molars by luminal unicystic ameloblastoma in the mandible. Cyst enucleation, curettage, and third molar extraction were done. No signs of recurrence or esthetic problems such as facial asymmetry were seen radiologically and clinically, up to 8 years 2 months postoperatively.

Cyst is pathologic disease develops in hard tissue as well as soft tissue, which is lined by epithelium filled with liquid, semi-liquid, or air. Origins and symptoms of the cyst are various according to region, and symptoms are malocclusion, diversion of root, tooth mobility, periapical swelling, discoloration and lesion expansion, because the odontogenic cysts begin in the numerous rests of odontogenic epithelium. But almost cysts produce no symptoms unless secondary infection occurs. Treatment of small cysts may include extraction, endodontic therapy, and apical surgery. Treatment of a large cysts usually involves surgical removal (enucleation), Marsupialization(a method of decompression) or combination of two before mentioned. Bone graft is done for helping of bone defect healing at the same time of enucleation This clinical research from January 2000 to December 2005, analyzed by the age, sex, classification, size, region, treatment method, whether or not of bone graft of cyst in the jaw in Daegu Catholic University Hospital.
