Black's classification

Cavity/restoration classification There are several classifications of cavities in the dental literature attempting to correlate site, size of lesion, and disease activity. The oldest, simplest, and probably most universal in acceptance is Black's classification.

Black's classification of caries lesions ![[images.png]] Black's class- Site I - Posterior restoration contained within the occlusal surface II -Posterior restoration including an approximal surface III-Anterior restoration including an approximal surface IV- only Anterior incisal edge restoration V- Buccal cervical surface restoration

It is based on caries lesions now often misused by dentists as a purely descriptive analysis of restoration site

Class I 1. [0, 0, 1, 1, 0] // Occlusal and Buccal 2. [0, 1, 0, 0, 0] // Lingual 3. [0, 0, 1, 0, 0] // Occlusal 4. [0, 1, 0, 1, 0] // Buccal=labial

Class II

  1. [1, 0, 0, 0, 0] // Mesial
  2. [0, 1, 0, 0, 0] // Distal
  3. [1, 0, 1, 0, 0] // Mesial Occlusal Distal
  4. [1, 0, 1, 1, 0] // Mesial Occlusal Distal Buccal
