Study Notes
Histopathology of Dental Caries - ICDAS Codes
- ICDAS Codes: International caries detection & assessment score
Moderate Stage Caries → Code 4
- Dark shadow from dentine with/without enamel breakdown
- White or brown spot when wet
- Darkened areas of intrinsic shadow (grey, blue, brown)
Extensive Stage Caries → Code 5
- A distinct cavity in opaque or discoloured enamel with visible dentine
- Visible evidence of dentine demineralisation
- White or brown wells
Extensive Stage Caries → Code 6
- An extensive cavity
- Visually able to see extension into dentine
Recap - Structure of Dentine
- The mineral component of dentine is hydroxyapatite
- Organic material is collagen
- This is a vital tissue as the dentin tubules are permeated with the cell process of the odontoblasts
- It therefore is able to defend itself from assault (alongside the pulp)
- We refer to this as the dentinal pulp complex as the 2 tissues are intimately related.
