Arrested root caries may need the use of flowable composite resins to improve esthetics. Objectives: To assess the efficacy of ozone (HealOzone, KaVo) to reverse shallow, non cavitated, leathery primary root caries lesions (PRCL's) which were approaching a hard consistency (J Dent Res 1993,73: 623-629) in an ageing patient group (>60, mean 72.3yrs, SD 5) and to subsequently assess the retention of a flowable composite resin to the ozone arrested lesions. Methods: A total of 62 subjects with 2 lesions each (124 PRCL's in total) were recruited. The lesions were randomly assigned into two groups; treated with ozone, or air. The Ozone treatment was applied by a different operator to the one recording the clinical criteria used to define the severity of the lesions. At baseline and at 1 month, the lesions were clinically assessed as soft, leathery or hard and received treatment as at baseline. At one month, all PRCL's were etched, and sealed using Bond-It and Flow-It (Pentron) and the subjects were recalled after a further 12 months. Results: After 1 month, 61 patients reattended. There were no observed adverse events. 60 of the ozone treated PRCL's had become hard and were therefore arrested, whilst only 24 of the control lesions arrested (p < 0.05). 56 subjects attended the 13 month recall. In the control group, 8 out of the 32 sealed non arrested PRCL's had a partial or complete loss of their sealant whilst in the test group only 2 of the 55 arrested PRCL's had a partial or complete loss of their sealant. Conclusions: Leathery non cavitated primary root caries, approaching a hard consistency can be arrested within one month after the use of ozone and the retention of sealants on these arrested lesions is very promising at 12 month recall.
