Caries prophylaxis by obstruction of the invasion roads
1.
1. Whether or not the invasion roads may be blocked by calcium deposition from the saliva apparently depends on some unknown quality of the saliva.
2.
2. People who are naturally caries immune are fortunate enough, apparently, to possess saliva of such quality that it has deposited calcium in these invasion roads.
3.
3. When the dentinal tubules are obstructed by calcium deposition and, as a result, opaque, nonsensitive dentine is produced, caries resistance is established.
4.
4. So now, when testing the ability of a chemical to produce caries resistance, we may use a different guide. Instead of employing the acidophilous count, we, may note the effectiveness of the chemical in question in desensitizing sensitive dentine.
5.
5. A saliva test for the enzyme will then show the presence or absence of caries-immune conditions for any certain dentition.
