Child with Primary and Transitional Dentition
The recall child patient with either a primary or transitional dentition who presents with no evidence of clinical caries or no increased risk factors for caries, may have proximal caries. As previously mentioned, increased caries risk has been demonstrated in specific subgroups of children17,18 and these data should be taken into consideration when determining the frequency of the radiographic examination. A posterior bitewing examination is recommended at 12 to 24 month intervals if the proximal surfaces of the teeth cannot be examined clinically. The interval recommendation is based on the rate of caries progression in primary and transitional dentitions. Children receiving routine dental care are more likely to be at a lower risk for caries.1
The recall adolescent patient with a permanent dentition who presents with no evidence of clinical caries or no increased risk factors for caries, may have proximal caries. As such, proximal carious lesions can only be identified through radiographic means. The radiographic recommendation consists of posterior bitewings at 18 to 36 month intervals. The time frame is based on the rate of caries progression in this age group while taking into consideration the caries susceptibility of young permanent teeth.
Adult Dentate, Partially Edentulous, Edentulous Patient
The recall adult dentate or partially edentulous patient who receives regular care and presents with no signs and symptoms of oral disease have a low caries risk. Caries risk factors may change over time and this must be taken into consideration when evaluating the adult recall patient. The recommended radiographic examination is posterior bitewings at 24 to 36 month intervals. Radiographic examination of the recall adult edentulous patient is not indicated.
