We developed computer software which works out the duration of decalcification and recalcification of the teeth based on the Stephan curve and the critical pH.
Making use of this software, we examined a total number of 234 children (115 males and 119 females)aged between three and fourteen with an average of six years of age and the following results were obtained.
1. The number of dental caries had a tendency to increase in proportion to the duration of decalcification.
2. The index of DMF (dmf) tooth correlated positively to the duration of decalcification significantly.
These results suggested that the duration of decalcification obtained by the use of this software correlated to the state of dental caries.
