Abstract
Pharmaceutical Sciences Behavior Oral Pediatric Dentistry (Director: Tsutomu Shimono)**Health Care Products Laboratory, KAO Corporation (Director: Toshiyuki Suzuki)Patients found with initial dental caries (white spots) under the recall system in The Pediatric Dental Clinic of Okayama Medical and Dental School and Hospital (14 Infants involving 37 teeth) were monitored under the special recall program using dual component dentifrice. This recall was undertaken 3 times.
The findings are as follows:
1. At the start of the program, The average age of the patients was 11 years 10 months. The average Cariostat®was 1.8. Their teeth were all anterior teeth.
2. To evaluate the effect of the program, we used the light-induced fluorescence method, and picked up an area of initial caries and a luminance rate of initial caries. Area of the initial caries signifies the width of the initial caries. And at the time immediately before beginning, the average of it was 7.4mm2. As the program, the area of initial caries decreased. At the area, there was a significant difference between the time of before beginning and the first recall, between the time before beginning and the second recall, between the time before beginning and the third recall.
3. The luminance rate of initial caries means the depth of the initial caries. As the program, the luminance rate of the initial caries decreased. There was however no significant difference between the time before beginning and other the recalls.
