An attempt to correlate dentin and pulp changes in human carious teeth.

O Skogedal, L Tronstad

Oral Surgery, Oral Medicine, and Oral Pathology

|January 1, 1977

Summary

Comparing carious teeth halves revealed similar dentin changes but variable pulp inflammation. This suggests bisected teeth may not be ideal for studying caries-related dentin and pulp reactions together.

Area of Science:

Dentistry

Cariology

Background:

Caries progression affects both tooth dentin and pulp.
Bisecting teeth is a common method to study these changes.
Comparability of changes in bisected teeth requires investigation.

Purpose of the Study:

To compare dentin and pulp changes in bisected carious teeth.
To assess the suitability of bisected teeth for studying caries-related reactions.
To determine if changes in each half of a bisected tooth are comparable.

Main Methods:

Contact microradiography for dentin mineralization analysis.
Histological examination of demineralized serial sections for pulp changes.
Comparison of mineralization and inflammation in contralateral halves of bisected carious teeth.

Main Results:

Dentin showed similar hypo- and hypermineralized zones in both halves.
Secondary dentin formation was comparable between the two halves.
Pulp exhibited significant inflammation and abscesses in one half, but only scattered cells in the other.

Conclusions:

Dentin changes in bisected carious teeth are generally comparable.
Pulp inflammation can be highly asymmetrical in bisected carious teeth.
Using bisected teeth to correlate dentin and pulp reactions to caries is questionable due to pulp asymmetry.
