2. Radiographic features of Superior
Foramina of the Nasopalatine canal
 The nasopalatine canal originates at two foramina in floor of the
nasal cavity.
 Radiographically, it can be recognized as two radiolucent areas
above the apices of the central incisors in floor of the nasal cavity
near its anterior border and both the sides of the septum.

8. RADIOGRAPHIC FEATURES OF THE
LATERAL FOSSA
 Also called as INCISIVE FOSSA.
 Appears as depression in the maxilla near the apex of
the lateral incisor .
 Appears diffusely radiolucent in the IOPA.

12. RADIOGRAPHIC FEATURES OF
NOSE
 The soft tissue of the nose is frequently seen in the
projections of the maxillary central and lateral incisors
,superimposed over the roots of these teeth.
 Image appears uniformly opaque with a sharp border.

18. RADIOGRAPHIC FEATURES OF
THE NASOLACRIMAL CANAL
 The nasal and maxillary bones form the nasolacrimal
canal.
 It runs from the medial aspect of the antero inferior
border of the orbit inferiorly, to drain under the inferior
conchae into the nasal cavity.
