Ozone continues to be investigated as a pharmaceutical treatm ent for pit and fissure carious lesions (PF CLs) in a longitudinal controlled clinical trial. Aim: To monitor lesions' remineralisation, arrest or progression after Ozone treatm e nt using ECM and DIAGNOdent readings. Met hods: 210 non-cavitated occlusal pit and fissure carious lesions in 47 patients were enrolled in this study. A fter clinical classification (Ekstrand, 1998) and cleaning using an airabrasive system; Prophyflex 2® (KaVo, Ger many), the DIAGNOdent® (D) (KaVo, Germany) and ECM (LODE BV, Netherlands) standard scale b aseline readings were tak e n over each specific tooth surface. After randomisation of lesions, 105 lesions were treated with Ozone for 10 seconds (HealOzone unit, CurOzone USA) and the other 105 were reserved as controls. After 1 & 3 months (m), the procedure was repeated. Results: The changes in the ECM values were tested by one sample t test of Log10 m/base. (Tt = Treatm ent Group, Cl= Control Group) Conclusion: Ozone significantly remineralised early Pit and Fissure Carious L esions (D<40) at three months. Further studies are required to study the effect of Ozone on PFCLs with baseline DIAGNOdent readings over 40. (Supported by CurOzone, USA).
