“…The results of our study are in agreement with the observations by Samuel et al 41 , who showed that ozone significantly improved the remineralizing capability of nano-hydroxyapatite on artificially induced enamel caries lesions compared to nano-hydroxyapatite alone. Results contrary to the present study were reported by Tahmassebi et al 42 , who analysed in vitro the effect of ozone on artificial caries-like lesions and concluded that ozone alone is not effective in promoting remineralization or preventing enamel demineralization unless combined with an agent containing high levels of fluoride. The diverse observations may result from a different way of ozone application and a different ozone generator.…”

The aim of the study was to assess the efficacy of three methods of enamel remineralization on initial approximal caries: (1) a nano-hydroxyapatite gel, (2) gaseous ozone therapy, (3) combination of a nano-hydroxyapatite gel and ozone. Patients (n = 92, age 20-30 years) with initial approximal enamel lesions on premolar and molar teeth (n = 546) were randomly allocated to three groups subjected to a 6-months treatment: Group I: domestic nano-hydroxyapatite remineralizing gel, group II: in-office ozone therapy, group III: both domestic remineralizing gel and ozone therapy. Caries lesions were assessed on bitewing radiographs at baseline, after 1 year and after 2 years. At one-year follow-up, the smallest rate of lesions with remineralisation (36.5%) was found in group I, and the highest (69.3%)-in group III. In group III a significant remineralisation was noticed in after 1 year and then a demineralisation after 2 years. Thus nano-hydroxyapatite gel and ozone therapy exert some capacities to remineralize approximal enamel and dentine subsurface lesions of premolar and molar teeth. Moreover, the combination of both methods produces the best effect compared to nanohydroxyapatite or ozone therapy applied alone. However, the treatment should be continued for a long time in order to achieve nonrestorative recovery of caries.

“…An increase in the S. mutans and Lactobacillus counts, seen during orthodontic treatment, might affect the balance of the oral flora and produce a cariogenic disposition (19). Ozone, which is a strong antioxidant and antimicrobial, is reported to be one of the agents that can be used to suppress cariogenic oral flora in at-risk individuals (4,20). However, owing to its strong oxidizing effect, ozone might have a negative impact on resin tooth adhesion (13).…”

Color change after tooth bleaching with ozone and 10% ozonized carbamide peroxide for in-office use

et al. 2022

There is a constant search for bleaching treatments that can offer greater safety with fewer adverse effects, especially in the techniques performed in the office, which usually employ hydrogen peroxide in high concentrations (35% to 40%) that are not recommended by some international control agencies. This in vitro study evaluated the color change after tooth bleaching with the use of ozone and a 10% ozonized carbamide peroxide bleaching treatment for in-office use. Thirty molars were allocated ( n = 10): three applications of ozone (1 hour every 3 days); three applications of 10% ozonized carbamide peroxide (1 hour every 3 days); 10% carbamide peroxide agent (8 hours a day for 7 days). The teeth were mounted on a plaster model to simulate the dental arch, and trays made of silicone were used for the application of the bleaching agents and to allow ozone to enter through. The ozone concentration used was 60 μg/mL, with an oxygen flow of 0.25 L/min. The values of color change showed no significant differences among treatments. The variations in the parameters over time, as well as the values of Δ E ab , Δ E 00 , and WI D , showed that there was no significant difference among the three treatments. The use of ozone and 10% ozonized carbamide peroxide for in-office use was effective for tooth bleaching with clinically perceptible and acceptable color alterations. The study was approved on September 10, 2019 by the São Leopoldo Mandic Ethics Research Committee (CAAE No. 17711719.4.0000.5374).
