Which radiograph view is most likely to determine the presence of an unerupted lateral incisor?

The anterior occlusal radiograph is particularly useful for visualizing the anterior teeth, including incisors. This view allows for a broader perspective of the upper and lower dental arches and provides clear details of unerupted teeth, including laterals. When assessing for unerupted lateral incisors, the anterior occlusal radiograph's unique perspective helps in identifying their positional relationship with adjacent teeth, the bone structure, and potential impaction.

The dental pantomograph, while beneficial for obtaining a comprehensive view of the entire mouth, may not provide the specific focus needed for diagnosing unerupted teeth in the anterior region. Similarly, horizontal bitewing radiographs are primarily designed to capture interproximal details of posterior teeth and are not suited for identifying issues with unerupted incisors. The lateral oblique view is more targeted for specific areas of the jaw and is less effective for general assessments of dental anomalies in the anterior segment.

In essence, the anterior occlusal radiograph is the most effective option among the choices given for determining the presence of an unerupted lateral incisor.
