Approximal caries The detection and diagnosis of approximal caries in posterior teeth is difficult because of the restricted access for visual inspection. Anonymous uqBeAy8on. Dentin caries In dentin caries, OCT can distinguish the lesion that penetrates into dentin [ 18 ]. J Am Dent Assoc. In this study, no cases of deep caries that required dental pulp treatments were included.

Tooth crack A tooth crack initially occurs on the enamel surface due to local stress concentration and grows with increased load and penetrates into the dentin [ 3536 ]. SS-OCT imaging for approximal caries was performed from the occlusal aspects of posterior teeth in a real clinical situation [ 29 ]. Seventy-five non-restored proximal surfaces of premolars and molars were selected from for the 53 healthy adults. Further development of the technology, such as systems with improved transmission into the soft tissue and special imaging probe for the detection of sub-gingival zone, can improve the diagnostic accuracy for the detection of tooth cracks and enhance its demand in clinical usage.
