Chapter
The difference between carious lesion diagnosis and carious lesion detection is discussed here. Concerning carious lesions, 3 diagnostic requirements should be fulfilled: to detect lesions, to assess surface integrity, and to assess lesion activity to support clinical decision making. The first and most important diagnostic method is meticulous vis...
Chapter
The detection of occlusal lesions is difficult because of the morphology of molars and premolars. Deep fissures are often plugged with organic material that can be stained over time or that can promote the beginning of the caries process. Deep fissures also often hamper direct sight of an existing incipient caries lesion that might therefore be det...
