In which periapical projection will the mental ridge be visible?

The mental ridge is a bony prominence located on the anterior mandible, typically more evident in periapical projections of the mandibular anterior teeth. In the case of the mandibular lateral and central incisors, the mental ridge can be prominently visualized due to the positioning of these teeth in relation to the mandible. When capturing a periapical projection of these areas, the mental ridge appears as a radiopaque area that provides valuable anatomical reference points for both diagnostic and treatment planning purposes.

The mental ridge may not be as visible in periapical projections of other areas such as maxillary molars, maxillary canines, or mandibular premolars because these sites are located either above or further back from the ridge itself. Specifically, maxillary structures do not typically showcase the mental ridge as it lies below the maxillary arch relative to the mandibular dentition. Understanding this anatomical relationship allows for improved interpretation of dental radiographs, particularly in identifying landmarks that assist in managing oral health conditions.
