Treatment Of Symptomatic, Deep, Almost Cariously Exposed Lesions Using Ozone
Objectives: Traditional management of symptomatic, deep, almost cariously exposed lesions usually involves removing the infected dentine which can be associated with postoperative sensitivity and/or root canal therapy (RCT). Ozone has been proven effective to kill dentine caries microorganisms (J Dent. 2009;37:449-53; Swed Dent J. 2008;32:139-47; Eur J Oral Sci. 2006 ;114:349-53; J Esthet Restor Dent. 2008;20:218-22). Ozone treatment of deep caries might allow a less invasive management strategy. The aim of this pilot study was to assess the pain VAS score and need for RCT after the use of a traditional caries removal and restoration method or after an ozone method of more conservatively managing the deep caries and restoration.
Methods: After ethics committee approval 20 subjects consented to be randomly allocated to receive either the traditional (n=10, 5 male, 5 female, mean age 24.1) or ozone (n=10, 5 male, 5 female, mean age 24.2) methods. The ozone method only differed from the traditional method by leaving the deep leathery caries on the pulpal floor and then treating this with 10 seconds of ozone from the healozone X4 (Curozone, Germany). A conventional glass ionomer cement (Riva Self Cure High Viscosity, SDI Australia) was placed followed by amalgam in each cavity. The pain VAS score was recorded before treatment and after 24 hours.
Results: The pain VAS score for subjects with the traditional treatment was 8.1 before treatment and 6.0 after 24 hours whilst these were 8.3 and 0.5 for the ozone treated subjects. After 3 months, 5 subjects required RCT from the traditional management group whilst no subject required RCT in the ozone group.
Conclusions:
Ozone treatment of symptomatic, deep, almost cariously exposed lesions shows promise to allow a more conservative approach to treating these extensive carious lesions as well as being associated with less postoperative sensitivity and less need for root canal therapy.
