Abstract
The purpose of this study was to evaluate the clinical and radiographic features of 35 cases of nasopalatine duct cyst by means of the analysis of periapical and/or occlusal radiograms in 35 persons visited the Department of Oral and Maxillofacial Radiology, School of Dentistry, Kyung Hee University and Chonbuk National University.
The obtained results were as follows :
1. The incidence of nasopalatine duct cysts was higher in males(74.3%) than in females(25.7%).
2. The nasopalatine duct cysts were the most frequently occurred in the 4th decades(34.3%). The-6th and 7th decades(17.1%, 17.1%) were next in order to frequency followed by the 5th decades(14.3%), the 3rddecades(8.6%), the 2nd decades(5.7%), and 8th decades(2.9%).
3. In the signs and symptoms of nasoplatine duct cysts, 25.7% were swelling, 17.1% were swelling and tenderness, 20.0% were swelling and pain, and 37.2% were asymptom.
4. In the shape of nasopalatine duct cysts, 40.0% were round type, 48.6% were oval type, and 11.8"Ic were heart type. In symmetry of the nasopalatine duct cysts to the median palatine nurture, 85.7% were symmetry, 14.3% were asymmetry.
5. In the width of nasopalatine duct cysts, 11.4% were 6-10mm, 48.6% were 11-20mm, 25.7% were 21-30mm, and 14.3% were 31.-40mm.
6. In the periphery of nasopalatine duct cysts, 82.9% were distinct, 17.1% were relatively distinct.
7. In the change of root, 51.5% were intact, 17.1% were root divergence, 20.0% were root resorption, and 11.4% were root divergence and resorption.
