A Dentigerous Cyst with Antro-Oral Fistula

Dentigerous cyst with oro-antral fistula

“…The cause of the formation of a fistula in a dentigerous cyst has been thought to be the presence of infection (Gadre, 1962;Setiya, 1965;Agarwal, 1966), but in the present case no features of active infection were present and hence it was different from other reported cases of dentigerous cyst with oro-antral fistula. It is surprising that the infection had not ascended, even in the presence of a fistulous tract.…”

“…This proliferation leads to epithelial granuloma formation. The centre of the mass undergoes liquefaction-necrosis, converting it into a cyst lined by squamous epithelium (Setiya, 1965). The essential feature of the dentigerous cyst is that it contains a whole or part of the tooth, depending upon the part of the follicle in which the cyst develops.…”

“…Bennett and Moore (1954) studied 29 cases of oro-antral fistula but did not find any which were secondary to dentigerous cyst. An extensive search of the literature revealed only two cases of dentigerous cyst with oro-antral fistula (Gadre, 1962;Setiya, 1965), and one case of dentigerous cyst with antro-cutaneous fistula (Agarwal, 1966).…”

Ectopic tooth in maxillary sinus: Case series

“…An extensive dentigerous cyst may surround the tooth or root and a fistula, either antro-cutaneous,[4] or antro-oral,[5] can develop. Maxillary sinus abnormalities occur in asymptomatic individuals and only X-ray of the antra reveals a cyst or tooth or both.…”

Ectopic Tooth in the Maxillary Antrum- A Mini Review

“…The problem of a tooth or root in the maxillary antrum can be a perplexing one. An extensive dentigerous cyst may surround the tooth or root and a fistula, either antro-cutaneous, [16] or antro-oral, [17] can develop. Maxillary sinus abnormalities occur in asymptomatic individuals and only X-ray of the antra reveals a cyst or tooth or both [18].…”
