Caries detector dyes...

 Is there any role of pH in the absorption of 

caries detector dyes on the dentinal surface?

What is a caries detector?

These dyes selectively stain infected demineralized dentine if so it acts as a clinical guide to remove irreversible decalcified tissue. Mainly used to diagnose occlusal caries.

Here we describe the application of the Ir/IrOx pH sensor, which is used to detect the pH of caries dentinal surface. The pH level is to distinguish between active and arrested caries.

The average pH values of active caries, arrested caries, and the sound root 6.85, 6.05, 5.30 respectively.

This caries testing technique using Ir/IrOx sensor gives accurate quantitative caries evaluation. 

What we eat, drink, change the pH level in our mouth which is responsible for an optimal environment for Bad breath which can cause caries in the tooth. 

When the pH level falls below the normal level, demineralization occurs. when teeth get bacteria, the oral cavity starts to release lactic acid which is the sign of demineralization process occurrence, causes tooth decay or tooth caries.

So it is recommended mostly that everyone should have to brush twice a day for maintenance of ph level. As we all have saliva formation which has a ph of 6.5-7.2 which is normal for our mouth and decreases the formation of caries, tooth decay.
