|2747 Successful Use of Airbrasion in Conjunction with Ozone Treatment|

Most research in the use of ozone in the remineralisation of carious dentine has been confined to the treatment of occlusal caries. However many carious lesions occur in other sites, interproximal caries being one of concern. Objectives: This investigation aimed to establish whether other lesions, especially interproximal and ‘occult' occlusal caries could be treated by using airbrasion, to gain access to the lesion, followed by Ozone treatment, and to assess if this conservative method was faster than conventional techniques. Methods: Lesions requiring drilling and filling were selected. 37 patients involving 48 teeth were treated with airabrasion and Ozone whilst the time required to restore 48 other teeth conventionally in the same patients was also recorded. Access to the lesion was obtained using airbrasion delivered at 80 psi using 27-micron aluminium oxide as the cutting agent (Abradent DV1). Once access to the caries was established, ozone was applied for 40 seconds using a HealOzone unit (CurOzone USA and KaVo Germany). In the treatment of interproximal caries, techniques have been explored to ensure an effective seal. Glass ionomer restorative (Fuji 9 (GC) or Diamond Carve (Kemdent)) restored the cavities. Results: All lesions were successfully exposed and a seal established for the delivery of ozone. Clinically acceptable seals have been achieved around all restorations. The airabrasion and Ozone technique was significantly faster than conventional drilling and filling (P<0.05). Conclusions: Airbrasion combined with Ozone treatment, because of its' minimal intervention capability, enables carious lesions other than fissure caries to be treated without out the need for local anaesthesia and saves time compared to conventional methods.
