A Case of a Dentigerous Cyst Causing Chronic Antral Infection

An Extensive Dentigerous Cyst with Antro-Cutaneous Fistula

“…Various authors including Durcan and Holden (1962), Gadre (1962) and Setiya (1965) have reported the occurrence of an oroantral fistula with a dentigerous cyst but no case could be found in the literature of a dentigerous cyst with an antro-cutaneous fistula. Although pressure atrophy of bone may facilitate the formation of such a fistula in the case of an ever enlarging cyst, yet why the fistula should occur on the top of swelling rather than on a dependent portion is difficult to explain.…”

Dentigerous cyst with oro-antral fistula

“…These clusters have been described as the epithelial debris of Mallasez, from which the lining of the dental cyst originates. Durcan and Holden (1962) have suggested that the epithelial rests of Mallasez are stimulated to proliferate by irritative conditions, such as sepsis, in the deciduous predecessor or in the adjacent teeth. This proliferation leads to epithelial granuloma formation.…”
