Proximal caries increment in connection with orthodontic treatment with removable appliances

The progression of proximal caries on canines, premolars and molars has been studied among 129 children treated with removable orthodontic appliances. The registration of carious lesions was performed on posterior bitewing radiographs taken before and after the orthodontic treatment. The children in this investigation showed a higher proximal caries progression than children treated with fixed orthodontic appliances where bands had been used. However, in comparison with caries data from epidemiological investigations in children of similar ages from the same area no difference was noted.
