Background: The incisive canal cysts are the non-odontogenic cysts of the oral cavity. They may be symptomatic or, more frequently, asymptomatic, and usually are seen radiographically when the radiograph is taken from other reasons. These cysts can be misdiagnosed as endodontic lesions. The aim of this study was to present patients surgically intervened because of incisive foramen cysts.
Case reports: Six patients have been included in the analysis. Asymptomatic development of the disease has
been presented in 4 cases, and symptoms of inflammation were observed in 2 cases. Radiological observed images of the cysts had dimensions from 8 mm to 20 mm. One patient had a cyst removed from the vestibular approach and the others were operated on with an approach from the palatal aspect. Autologous bone graft was used in two cases, biological active glass was implanted in two cases (in one case with mixture with autologic bone) and β-tricalcium phosphate in two case and liquid membrane was applied in two cases (in one case in combination with β-tricalcium phosphate). Long-term post-operational course revealed complications in none of the described cases. In one patient paraesthesia occurred post-operationally which disappeared within 3
Conclusions: Concluding, incisive foramen cysts may cause diagnostic difficulties. In order to extirpate the cyst good visibility is vital. It can be achieved by an approach from the vestibular side. Because of a related to this approach bone defect and frequently occurring haemorrhage haemostatic osseosubstitute can be efficiently applied. Biological active glass is such a material. In case of cyst follicle connected with palatal mucosa [more frequent in this study] the easiest approach is from the palatal aspect. In any case it is always recommended to save the nasopalatal nerve.
