6. 임상적으로 방사선사진을 참고로 함치성낭종이라 잠정진단되었던 117예 중에서, 함치성낭종으로 확진된 예는 92예(79%)였으며, 함치성낭종서 유래된 벽제성 법랑아세포종(mural ameloblastoma) 7예(7%), 연상된 편평상피세포암종 1예, 기타 17예(14.5%)가 있었다.
7. 함치성낭종은 잠재성 합병증을 방지하고 재발을 막기 위해서 가능한 한 냉동표본검사를 이용한 완전적출술과 적출물의 병리조직학적 검사 및 술후 세심한 관찰과 치료가 매우 중요하리라 사료되었다.

The dentigerous cyst originates through alteration of the reduced enamel epithelium after the crown of the tooth has been completely formed, with accumulation of fluid between the reduced enamel epitheliun and the tooth crown.
It is very important clinically because several serious potential complications exist stemming from the dentigerous cyst, besides simply the possibility of recurrence following incomplete surgical removal.
The author has studied clinically and histopathologically about one hundred and seventeen biopsy specimens and charts collected from department of oral surgery and oral pathology, College of dentistry, Yonsei University, Seoul National University and Kyung Hee University during the period of January, 1977. to August, 1982. which had been diagnosed clinically and radiologically as dentigerous cyst.
The results were as followings:
1. The moat common complaints were swelling and pain. Other symptoms included pus discharge, delayed eruption of tooth and unhealed postextraction wound.
2. In the sex incidence of 92 cases of dentigerous cyst, 61 cases(67%) were in male and 31 cases(34%) in females.
The average age was 23.7 years, and more decreased in the incidence after 30 years.
3. The most common location of the dentigerous cyst was the anterior regions of the maxilla, where were many supernumerary teeth.
4. The histologic pattern of epithelium lining cysts showed mainly stratified squamous epithelium, and ciliated epithelium were fecund partly in association with nasal and maxillary sinus mucosa.
5. Heterogenous histopathologic features of dentigerous cyst showed keratinization in 13 cases, daughter cyst 3 cases & severe epithelial hyperplasia 10 cases.
6. Among the 117 dentigerous cyst diagnosed clinically and radiologically, 92 cases(79%) were dentigerous cyst, 7 cases mural ameloblastoma, 1 case suggested epidermoid carcinoma other differential diagnosis 17 cases(14.5%).
7. In treatment of dentigerous cyst, complete enucleation using frozen section, histopathologic examination and post-op clouted observation and care were very important to prevent the potential complications and recurrence of dentigerous cyst.
