Bite-wing:Used primarily to detect interproximal caries,occlusal caries that have penetrated into thedentin, and possible caries under existingrestorations. - A bite-wing radiograph will show:• Surfaces involved• Depth of the lesion in relation to the pulp• Presence or absence of certain permanent teeth
Periapical:Used primarily to detect both normal conditions,and pathology involving the roots of the teeth and theirsupporting structures - A periapical radiograph will show :• Furcation or apical involvement.• Presence of calcified tissues.• External root or bone resorption.• Internal root resorbtion.• Anomalies of the supporting bone and associatedstructures (cysts, supernumary or ectopically eruptingteeth, etc.
Panoramic:Used primarily to provide baseline data for growth and development, and to evaluate changes that are occurring over time. - A Panoramic radiograph will show:• Presence or absence of permanent teeth• Positions of the permanent teeth in relation to the primary teeth• Evaluation of bony lesions and TMJ
