|3470 Clinical Reversal of Occlusal Pit and Fissure Caries Using Ozone|
A. HAMID, University of London, United Kingdom|
Ozone has been shown in many studies to clinically reverse primary root carious lesions and early occlusal pit and fissure caries. This study aimed to assess the use of Ozone to manage pit and fissure caries extending up to 1 mm into Dentine. Objectives: This study assessed the effect of a novel Ozone delivery system1 on non cavitated primary pit and fissure carious lesions over a 6 month period.
Methods: 184 subjects were randomly allocated to one of 2 groups. 92 subjects were entered with 92 carious lesions whilst another 92 subjects were entered with 92 control lesions, which did not receive any Ozone or conventional treatment. Each carious lesion had been deemed to require conventional drilling and filling. Teeth were cleaned (Prophyflex 2®, KaVo, Germany) and the following were recorded: clinical severity (Ekstrand KR et al, Caries Res. 1998; 32: 247-54.) and DIAGNOdent® (KaVo, Germany). After randomisation of Subjects, Ozone was applied to each test lesion for 40 seconds both at baseline and at 3 months. After 6 months, subjects were recalled and the lesions were clinically re-assessed for severity.
Results: There were no observed adverse events. 86.6% of the ozone treated primary pit and fissure carious lesions had clinically reversed based on the clinical measurement of lesion severity whilst the control lesions did not significantly change clinically .(P<0.05). The DIAGNOdent® values correlated with the clinical findings. Conclusions: This treatment regime using Ozone is an effective alternative to conventional "drilling and filling" for primary occlusal fissure carious lesions.
