is now being investigated as a pharmaceutical treatment
for occlusal caries in permanent and primary teeth.
To assess and monitor the progression of carious lesions using
both DIAGNOdent® (KaVo, Germany) and Electrical Caries
Monitor (ECM, LODE BV, Netherlands) standard scale readings
after Ozone treatment in primary teeth.
17 patients with 50 non-cavitated occlusal carious lesions
were recruited. All teeth were cleaned by an air-abrasive
system called Prophyflex 2® (KaVo, Germany) before DIAGNOdent,
ECM standard scale readings and clinical classifications (Ekstrand,
1998) were recorded. After randomisation, half of the lesions
were treated with Ozone using a silicone-sealed cup via a
hand piece (HealOzone unit, CurOzone USA) for 10 seconds,
whereas, the other half was reserved as a control group. The
DIAGNOdent, ECM standard scale readings and clinical classifications
readings were repeated after 3 months.
ECM readings were increased significantly (p<0.05) and
DIAGNOdent readings were reduced significantly (p<0.01)
in the test lesions compared to the control lesions.
Reduced DIAGNOdent readings have previously been shown to
correlate with reduced lesion severity whilst higher ECM values
correlate with less porosity within lesions, reflecting their
reduced severity. These DIAGNOdent and ECM changes imply healing.
