LEC 2 Flashcards
Carries affecting pits and fissures on occlusal third of molars and premolars, occlusal two thirds of molars and premolars, and lingual part of anterior teeth
Class I
Cavity affecting proximal surfaces of molars and premolars
Class II
Caries Affecting proximal surfaces of central incisors, lateral incisors and cuspids without involving the incisal angles.
Class III
Caries affecting proximal including incisal angles of anterior teeth.
Clas IV
Caries affecting gingival one third of facial or lingual surfaces of anterior or posterior teeth.
Class V
Caries affecting cusp tips of molars, premolars and cuspids.
Class VI
Sound Surface
Score 1
First visual changes in enamel (seen only after prolonged air-drying or restricted to within the confines of a pit of fissure).
Score 2
Distinct visual change in enamel.
Score 3
Localized Enamel breakdown. (Without clinical signs of dentin involvement).
Score 4
Underlying dark shadows from dentin.
Score 5
Distinct cavity with visible dentin.
Score 6
Extensive distinct cavity with visible dentin.
Score 7
White or discolored enamel, no cavitation clinically.
Grade 1
Small cavitation in enamel.
Grade 2
Moderate sized cavity in enamel with exposed dentine (verified by probing).
Grade 3
Large cavity in enamel and moderate cavity in dentin.
Grade 4
Extensive cavity in enamel and substantial loss of dentin.
Grade 5
White or brown discoloration in enamel. No clinical cavitation. No radiographic evidence of carries.
Grade 1
Small cavity formation or discoloration of the fisher with surrounding gray or opaque enamel and or radiolucency in enamel on radiograph.
Grade 2
Moderate size cavity and radiolucency in the outer third of dentin.
Grade 3
Big gravitation and radiolucency in the middle third of dentin.
Score 4
Very big cavity and or radiolucency in the inner third of dentin.
Grade 5
Radiolucency in outer half of enamel
Grade 1
