classification of caries Etymology: L, classis, collection, facere, to make, caries, decay a system for dividing dental caries into several classes based on the part of the tooth they affect. Class I caries are pits and fissures in the facial and lingual surfaces of maxillary incisors. Class II caries affect the proximal surfaces of premolars and molars but have not broken through to the occlusal surfaces. Class III caries affect the proximal surfaces of incisors and canines, excluding the incisal angles. Class IV caries affect the proximal surfaces of incisors and canines, including the incisal angles. Class V pertains to caries other than pits and fissures that affect the gingival third of the labial, buccal, and lingual surfaces. A modification of this classification system (not included in Black's Classification) adds another group, Class VI, consisting of caries on the incisal edges and cusp tips. Also called Black's Classification of Caries, artificial classification of caries. See also cavity classification. How to thank TFD for its existence?
