The nasopalatine duct cyst presents as a cyst of non-odontogenic origin, whose etiology has not yet been defined. However is believed in the theory of the proliferation of embryonic remains of the nasopalatine duct that leads to its formation. It is often detected in routine radiological examinations, which shows characteristics of a radiolucent lesion, defined, with a radiopaque halo, with a heart format due to overlapping of the anterior nasal spine. Because of this, it can be easily confused with an inflammatory periapical cyst from the upper central incisors. Besides, clinically the patient may complain of pain and swelling in the anterior region of the hard palate. The pain, pus, and swelling are usually associated with secondary infection. The present study aims to report a successful clinical case, of the diagnosis of a nasopalatine duct cyst, where the pulp sensitivity test and computed tomography helped in the treatment, that consisted in palatal access and total enucleation of the lesion. The recurrence of this cyst is low and usually affects adults from the fourth to the sixth decade of life. Treatment consists of total enucleation for small cysts or marsupialization followed by enucleation for larger cysts. This way, the imaging exams, and the clinical exam assist in the correct diagnosis, enabling the correct treatment. In our case, the total enucleation of the lesion was satisfactory, since, it did not cause damage to the adjacent structures and was the definitive treatment in only one surgical time. The patient continues been followed up, not showing symptoms or recurrence.
