Some Dentists are currently treating stained carious lesions = with Ozone=20 without placing any restoration whilst others are bonding = composite resin=20 on top of the Ozone treated stained lesion. Objectives: The aim of = this=20 study was to assess the placement time required and durability of=20 restorations placed on Ozone treated carious lesions as well as to = assess=20 the aestetics of these restorations from a Patients perspective. = Methods:=20 100 lesions in 50 subjects (2 per subject) were treated with Ozone = from=20 the HealOzone system (KaVo, Germany) for 40 seconds. Immediately = after=20 Ozone treatment, 50 randomly chosen lesions (1 per subject) were = etched=20 for 15 seconds with 37% Phosphoric Acid Etching Gel and sealed = with=20 Nano-Bond Adhesive (Pentron Clinical Technologies,Wallingford, CT = USA=20 06492), cured using Ultralume 5 (Ultradent Products, South Jordan, = Utah=20 84095) for 20 seconds, and Simile Nano-hybrid Composite (Pentron) = was=20 placed and cured for 20 seconds. The remaining 50 Ozone treated = lesions=20 served as controls. Results: The mean (SD) time required to Ozone = treat=20 and place a restoration was 3 (1) minutes. After 6 weeks, 100% of = all=20 restorations scored alpha in every recorded USPHS criteria. The = test=20 lesions were scored aesthetically as excellent in appearance in = 100% of=20 cases whilst the control lesions were scored aesthetically as = excellent in=20 only 10% of cases (P<0.01). Conclusions: An Ozone treatment and = subsequent restoration can be completed in 3 minutes and the early = results=20 of aestetically improving the appearance of Ozone treated stained = caries=20 are excellent using the above technique and materials and the = restorations=20 are durable.=20
