Treatment of symptomatic, deep, almost cariously exposed lesions using ozone

Abstract

The aim of this controlled randomized crossover study was to assess post-treatment pain and the need for root canal treatment after the use of a traditional caries removal method followed by restoration, or after an ozone method of more conservatively managing the deep caries and a restoration. 84 participants (42 males and 42 females, mean age ± SD = 23.9 ± 2.0 years) were randomly allocated to receive either a traditional (n = 42, 21 males and 21 females) or ozone (n = 42, 21 males and 21 females) method. The ozone method only differed from the traditional method by leaving the deep leathery caries on the pulpal floor and then treating this with 20 s of ozone from the healozone X4 (Curozone, Germany). All caries was removed in the traditional group. A conventional glass ionomer cement (Riva Self Cure High Viscosity, SDI, Australia) was placed followed by a bonded composite resin restoration (Filtek Z250 Universal Restorative, 3 M ESPE, USA) in each cavity. The visual analogue scale was used to assess pain scores before treatment and after 24 h. The participants were then followed up for 2 years to assess the need for root canal treatment. Statistical significance levels were set at α ≤ .05. Both groups were associated with significant reduction of pain scores 24 h after treatment (p < .0001). The ozone treatment was associated with less pain 24 h after treatment (p < .0001) and less need for root canal treatment (p = .014), after 2 years follow up, than the conventional treatment. In conclusion, treatment of symptomatic, deep carious lesions by ozone following partial removal of caries was accompanied with less pain and occurrence of RCT after treatment compared to traditional complete caries removal.

Direct Pulp Capping with Advanced Platelet-Rich Fibrin: A Report of Two Cases

“…We use gaseous ozone to treat the pulp wound and dentin. Gaseous ozone stimulates dentinogenesis [ 22 ]. Our studies have proven that 24 s of gaseous ozone application removes cariogenic microbes in the cavity after removing infected dentin; it has a disinfection effect [ 13 ].…”

“…Observou-se que o uso de ozônio em cáries muito profundas reduz a necessidade de tratamento endodôntico e é considerada como uma abordagem conservadora e promissora (Al-omiri et al, 2021). Eles incluem métodos manuais e dispositivos automatizados.…”

Current Strategies to Control Recurrent and Residual Caries with Resin Composite Restorations: Operator- and Material-Related Factors

“…Conversely, calcium hydroxide and glass ionomer liners proved successful in reducing the number of viable bacteria remaining and the quality of residual caries left behind after partial caries removal [ 34 ]. To arrest residual caries and enhance remineralization in deep carious lesions managed by partial caries removal, ozone and silver diamine fluoride treatments were suggested [ 35 , 36 , 37 ]. Further studies are needed to confirm procedural effectiveness, any adverse effects on bonding, biocompatibility, or deep penetration, and esthetic consequences [ 38 ].…”
