CASE REPORT
A 42-yr-old male was referred to the Endodontics Department, Naval Dental School (Bethesda, MD) to evaluate a possible sinus tract on the palate associated with the maxillary right central incisor. The patient was asymptomatic and had no knowledge that there was anything present on his palate. A review of his past dental history revealed that he had traumatized the anterior area ∼25 years previously and the maxillary right central incisor had been endodontically treated. In 1994, he noticed
DISCUSSION
Radiographically, the usually singular nasopalatine foramen may actually present as up to six separate foramina. This separation occurs most commonly as two foramina with separate left and right neurovascular bundles. There may also be separation of the neural and vascular components into three or four foramina. The foramina carrying the vascular components are called the foramina of Scarpa. Additionally the afferent and efferent vessels may separate for a possibility of up to four foramina of

2021, Journal of EndodonticsCitation Excerpt :However, the positive sensitivity tests were contradictory. It is well recognized that nonodontogenic pathoses can also explain these findings because they may mimic endodontic pathoses.1,6,7,11,12 In most cases, they mimic asymptomatic apical periodontitis,1,4 but they can also mimic root resorption13 or a CAA in rare cases.7,12

2013, Journal of EndodonticsCitation Excerpt :Retrospectively, after a complete treatment record review and radiographic analysis, multiple diagnostic interventions might have prevented an undesirable outcome. The nasopalatine duct region is an area in which radiographic superimposition of either the incisive foramen or an NPDC over the apex of 1 or both central incisors can lead to inaccurate endodontic diagnosis and improper treatment (1, 3, 7). NPDCs can present at any age but are predominantly associated with men in their fourth to sixth decades of life (8).
Differential diagnosis of apical periodontitis and nasopalatine duct cyst
2011, Journal of EndodonticsCitation Excerpt :The prevalence of NPDC is higher among men in their third and fourth decades of life (29, 30), and the cases described here confirm it. NPDC, which accounts for 1.3% to 4.2% of nonodontogenic cysts, has a less aggressive behavior, low recurrence rates, and limited growth (25, 28–34). The optimal approach to the treatment of NPDC is surgical enucleation because of its cyst-like features (25, 29–32).
