Occlusal hidden caries in permanent molar is a term used to describe occlusal dentin
caries, which is not diagnosed clinically due to the occlusal surface appears obtensity intact with
minimal demineralized enamel. However, bitewing radiographs show radiolucencies in dentin.
Two patients with occlusal hidden caries are presented in this article. Oral examination of these
patients did not reveal cavities on occlusal surfaces but large carious lesions were observed in
bitewing radiographs. These lesions when appropriately treated, before being harmful to dental
pulp, tooth loss and high treatment expense can be avoided.
