Intraoral radiographic techniques

• Occlusal radiography
  • Maxillary occlusal view
  • Mandibular occlusal view
  • Maxillary and mandibular occlusal views are subdivided into:
    • Cross-sectional occlusal view
    • Topographic occlusal view—anterior/posterior
    • Pediatric occlusal view.

“Role of paralleling technique in intraoral radiography: Questions answered”

• Intersection of maxillary sinus and the nasal cavity seen on the radiographs is called as ‘Y’ line of Ennis.
• It was reported by a researcher in oral radiology named Dr Ennis.
• In periapical region of maxillary canine, IOPA the lateral wall of nasal fossa and anterior border of maxillary sinus forms an inverted Y which is termed as “ Inverted Y of Ennis”.
• On radiograph, it appears as a radiopaque upside down ‘Y’ formed by the lateral wall of the nasal fossa and the anterior border of maxillary sinus.
• Inverted Y is located above the maxillary canine.
