“…Ozone gas was distributed to the tooth surfaces through disposable silicone cups provided by the manufacturer and assured a perfect seal to prevent any ozone leakage. The healOzone X4 machine only supplies ozone once the cup provides an absolute seal; this element allows the machine to be safely employed to humans 17 , 31 . Subsequently, application of 38% H 2 O 2 gel (BMS white 38%; BMS Dental) followed for 20 minutes.…”

The clinical efficacy regarding bleaching sensitivity and tooth shade lightening using a standard hydrogen peroxide (H2O2) bleaching gel was compared with the additional use of ozone either before or after application of H2O2. Using computer-generated tables, 45 participants were randomly allocated into three groups (n = 15 each) in this investigator-driven, single-centre trial. In Group 1, upper anterior teeth were bleached using ozone (produced via a healOzone X4 device) for 60 seconds, then 38% H2O2 for 20 minutes; in Group 2, 38% H2O2 application (20 min) was followed by ozone (60 s); air produced by the healOzone machine (60 s) followed by 38% H2O2 (20 min) was used in Group 3 (control). Bleaching sensitivity was evaluated via visual analogue scales, and a treatment-blinded reader objectively recorded tooth shades using a colorimeter before and 24 hours after bleaching (at α = 0.05). The H2O2/ozone combination did not result in pain sensations, while both ozone/H2O2 and H2O2 alone increased bleaching sensitivity (p < 0.001). Teeth achieved lighter shades (higher L*/lower b* values) after bleaching in all groups (p < 0.001), while Ozone boosted lighter tooth shades, irrespective of its use before or after H2O2 (p < 0.05). Due to the complimentary effects, applying ozone after H2O2 seems preferable for bleaching.

“…In the present audit gaseous ozone was used. The choice of gaseous ozone was based on the ozone generator cur- rently available and in use by the authors, it has been approved for use in the EU and room contamination and staff and patient exposure can be significantly reduced by adherence to safety measures including application of suction [18,22]. Attention to safety is important with ozone.…”

“…To make sure that the observed therapeutic effect was that of ozone patients were also instructed not to use any of the available antimicrobials after the treatment with ozone. It is known that agents like chlorhexidine are being used as part of the chemo-mechanical treatment approach of chronic periodontitis and can significantly reduce the depth of deep and medium-deep pockets [22]. Patients were given oral hygiene instructions and were asked to keep their oral hygiene daily diary.…”

Objectives: To evaluate the effects of ozone in periodontal treatment in dental practice. Methods: An evaluation of the current state of knowledge regarding the application of ozone in periodontal treatment revealed limited available literature. Therefore an audit was conducted in dental practice in order to evaluate the effects of ozone in periodontal treatment. Twenty-five patients were treated with gaseous ozone after having had failed conventional periodontal treatment. BPE scores and the six deepest pockets were measured in each patient before and after the use of ozone. Results: From the initial number of twenty-nine patients selected, twenty-five patients attended both follow up appointments. Based on BPE scores, twenty of the patients have overall improvement while five of the patients continued to have deterioration. Eight patients had an improvement in depths of periodontal pockets by three millimetres, sixteen patients had improvement by one to two millimetres and one patient did not improve. The depth of pockets after the use of ozone decreased significantly (P < 0.001). Conclusion: The audit revealed that gaseous ozone significantly (P < 0.001) reduced the depth of pockets in patients with periodontal disease. The positive results encourage further investigation in the subject.
