Methods: 20 children took part in this study and were divided into two groups. Laser group received CRA management, periodical visual and tactile examination and laser assisted caries process progression with Diagnodent device. Non-laser group received CRA management, periodical visual and tactile examination. For Diagnodent scanning, at first, the flat surface was divided into four portions and the midpoint of each quadrant was chosen for Diagnodent scanning. The midpoint of each proximal surface was chosen for Diagnodent scanning of the proximal surfaces. Finally, the mean score of Diagnodent scale was chosen as an index to determine the patient cooperation in control of dental caries progression.
Results: Diagnodent scale after 1 year and 2 years of the study in the two groups were different, so that in the laser group the Diagnodent scales for both proximal and flat surfaces were better than non-laser group (P=0.00). DMFS index in the two groups after 1 year was not significantly different, but after 2 years follow-up the DMFS index was significantly different (P=0.02).
Conclusions: Diagnodent scanning for monitoring of dental caries progression is an effective device in management of CRA.
