The following is a table which gives an overview of the protocol for taking radiographs on patients as they enter the clinic for diagnosis and treatment.  It is the one recommended by the American Academy of Pediatric Dentistry.  Each practitioner will have his or her own criteria:

Patient Category

Adolescent

Adult

 

Primary Dentition (prior to eruption of first permanent tooth)

Transitional Dentition (following eruption of first permanent tooth)

Permanent Dentition (prior to eruption of third molars)

Dentulous

Edentulous

New patient

All new patients to assess dental diseases and growth and development

Posterior bite-wing examination if proximal surfaces of primary teeth cannot be visualized or probed

Individualized radiographic examination consisting of periapical/occlusal views and posterior bite-wings or panoramic examination and posterior bite-wings

Individualized radiographic examination consisting of posterior bite-wings and selected periapicals. A full mouth intraoral radiographic examination is appropriate when the patient presents with clinical evidence of generalized dental disease or a history of extensive dental treatment.

Full mouth intraoral radiographic examination or panoramic examination
