Which intraoral projection is described as targeting the apex of the maxillary central incisor?

• A. Occlusal radiograph
• B. Posterior periapical radiograph
• C. Bitewing radiograph
• D. Anterior periapical radiograph (maxillary central incisor PA)

Answer: (D)

To image the apex of the maxillary central incisor, use an anterior periapical projection. This view is designed to visualize the periapical region of the front teeth, placing the receptor and directing the beam so the root tip of the central incisor (and surrounding bone) is clearly captured. It’s especially useful for evaluating apical pathology, trauma, or healing in the anterior region. Other projections image different areas: an occlusal radiograph covers a broader area of the jaw such as the palate or floor of the mouth rather than focusing on a single tooth apex; a posterior periapical radiograph targets the back teeth and their apices; bitewings show the crowns and the interproximal bone between adjacent teeth, not the apices.
