Ozone Efficacy in Treatment of Occlusal Caries in Primary Teeth

. OT. ABU-SALEM*, MM. MARASHDEH, E. LYNCH (Oral Health Care Research Centre, School of Dentistry, QUB, Belfast, UK). Ozone is now being investigated as a pharmaceutical treatment for occlusal caries in permanent a primary teeth. Objectives, To assess and monitor the progression of carious lesions using b DIAGNOdent® (KaVo, Germany) and Electrical Caries Monitor (ECM, LODE BV, Netherlan standard scale readings after Ozone treatment in primary teeth. Methods, 17 patients with 50 no cavitated occlusal carious lesions were recruited. All teeth were cleaned by an air-abrasive syst called Prophyflex 2® (KaVo, Germany) before DIAGNOdent, ECM standard scale readings a clinical classifications (Ekstrand, 1998) were recorded. After randomisation, half of the lesions w treated with Ozone using a silicone-sealed cup via a hand piece (HealOzone unit, CurOzone US for 10 seconds, whereas, the other half was reserved as a control group. The DIAGNOdent, EC standard scale readings and clinical classifications readings were repeated after 3 months. Resu ECM readings were increased significantly (p<0.05) and DIAGNOdent readings were reduc significantly (p<0.01) in the test lesions compared to the control lesions. Discussion, Reduc DIAGNOdent readings have previously been shown to correlate with reduced lesion severity wh higher ECM values correlate with less porosity within lesions, reflecting their reduced sever These DIAGNOdent and ECM changes imply healing within the Ozone treated lesions. Conclusio In Deciduous teeth, Ozone efficiently enabled remineralisation of carious lesions with corresponding reduction in their porosity as measured by the ECM and DIAGNOdent respectively
