• Clinical Classification of Caries:
1️⃣ According to Anatomical Site –
- Pit & fissure caries
- Smooth Surface Caries
- Root caries
2️⃣ According to rate of caries progression –
- Acute dental caries
- Chronic dental caries
3️⃣ According to nature of attack-
4️⃣ Based on chronology –
- Infancy caries
- Adolescent caries
A. Pit & Fissure Caries:
B. Smooth surface caries:
- On proximal surface of teeth or gingival 3rd of buccal & lingual preceded by formation of plaque.
- Early while chalky spot – decalcification of enamel.
C. Linear Enamel Caries:
- Atypical form
- Found in primary dentition
- Gross destruction of labial surface of incisor teeth
D. Root caries:
- Soft progressive lesion that is found everywhere on root surface that has least connective tissue attachment & is exposed to oral enviornment.
- Older age group & gingival recession
E. Acute Dentinal Caries:
- Rapid clinical course
- Early pulp involvement
- Initial lesion is small, while rapid spread of process at DEJ & diffuse involvement of dentin produce large internal excavation.
F. Rampant Caries:
Sudden, rapid & almost uncontrolled destruction of teeth affecting surface that are relatively caries free.
G. Nursing bottle caries (Baby bottle syndrome)
Affect deciduous teeth due to prolonged use of nursing bottle containing milk, sugar or honey.

H. Chronic dental caries: (Slower progress)
I. Recurrent caries: (Presence of leaky margins)
J. Arrested caries:
- No tendency of future progression, caries become static.
- Brown pigmentation in the hard tissue.
