Traditional restorative treatment for a carious lesion involves several invasive steps. The treatment of a primary carious lesion by means of ozone does not require any invasive treatment, simply the isolation of the tooth and the application of the ozone via the novel ozone delivery system1. Objectives: This study aimed to assess the differences in time expenditure in providing treatment with ozone compared with traditional ‘drill and fill' methods by measuring the actual time taken to deliver both treatment modalities. Method: 40 adult patients judged to have an early primary fissure carious lesion were randomly divided into two equal groups. The first group had traditional ‘drill and fill' treatment; the second group was treated by the application of ozone. Both groups were treated by the same dentist and dental nurse. Each patient's treatment was timed, in minutes, from the patient sitting in the dental chair until the completion of the procedure. Results: The conventionally treated (i.e. ‘drill and fill') patients averaged 35 minutes per patient with a SD of 10 minutes whilst the group treated by therapeutic ozone averaged 8 minutes with a SD of 2 (P<0.05). The actual time taken in the application of ozone was less than one minute per tooth. Discussion: This has profound implications for general dental practice, as the time required for ozone treatment is markedly less than conventional treatment. Conclusions: The use of ozone as treatment for primary occlusal caries was found to take less than one quarter the time required for conventional ‘drilling and filling' techniques. 1HealOzone unit, CurOzone USA and KaVo Germany.
