Effects of systemic ozone administration on the fresh extraction sockets healing: a histomorphometric and immunohistochemical study in ratsStudies have highlighted numerous benefits of ozone therapy in the field of medicine and dentistry, including its antimicrobial efficacy against various pathogenic microorganisms, its ability to modulate the immune system effectively, reduce inflammation, prevent hypoxia, and support tissue regeneration. However, its effects on dental extraction healing remain to be elucidated. Objective: Therefore, this study aimed to evaluate the effects of systemically administered ozone (O 3 ) at different doses in the healing of dental extraction sockets in rats. Methodology: To this end, 72 Wistar rats were randomly divided into four groups after extraction of the right upper central incisor: Group C -control, no systemic treatment; Group OZ0.3animals received a single dose of 0.3 mg/kg O 3 ; Group OZ0.7 -a single dose of 0.7 mg/kg O 3 ; and Group OZ1.0 -a single dose of 1.0 mg/kg O 3 , intraperitoneally. In total, six animals from each group were euthanized at 7, 14, and 21 days after the commencement of treatment. Bone samples were harvested and further analyzed by descriptive histology, histomorphometry, and immunohistochemistry for osteocalcin (OCN) and tartrate-resistant acid phosphatase (TRAP) protein expression. Results: All applied doses of O 3 were shown to increase the percentage of bone tissue (PBT) after 21 days compared to group C. After 14 days, the OZ0.7 and OZ1.0 groups showed significantly higher PBT when compared to group C. The OZ1.0 group presented the most beneficial results regarding PBT among groups, which denotes a dose-dependent response. OCN immunostaining was higher in all groups at 21 days. However, after seven and 14 days, the OZ1.0 group showed a significant increase in OCN immunostaining compared to C group.No differences in TRAP+ osteoclasts were found between groups and time points. Conclusion: Therefore, O 3 therapy at higher doses might be beneficial for bone repair of the alveolar socket following tooth extraction.

“…Ozone used for medical applications such as wound healing must be produced from pure oxygen through silent electrical discharge/DBD. The ozone generator and delivery system as an oxygen source must have a medical level of purity to avoid nitrogen and other impurities because nitrogen can produce NO, which is toxic to tissues [27]. The Double Dielectric Barrier Discharge (DDBD) Plasma Reactor qualifies as a medical reactor because there is a space between the two barriers for the flow of pure oxygen that is not mixed with nitrogen so that when it reacts with an electric field, high-purity ozone is produced.…”

Oil is one of the most popular media for the ozonation process compared to other media such as water or saline methods or direct exposure to blood. Ozonated oil has an advantage over other ozone therapy methods because ozonated oil has an antiseptic activity that is several hundred times higher than ozonated saline. Sumbawa oil is one of the local wisdom products of the Sumbawa tribal community, which is generally used as medicine or massage therapy to heal injuries such as broken bones, tendonitis, bruises, back pain and treatment of various skin wounds. An ozonation process can be carried out to increase the ability of Sumbawa oil to regenerate skin and repair tissue. Ozonation uses a Double Dielectric Barrier Discharge (DDBD) plasma reactor. The DDBD Plasma Reactor is a reactor that can produce ozone gas with very high purity. Pure ozone gas is very well applied in the medical world. This research aims to increase the peroxide levels in Sumbawa oil by ozonation using a Double Dielectric Barrier Discharge (DDBD) Plasma reactor. The flow rates used were 0.1 L/minute, 0.4 L/minute and 0.7 L/minute for 1 hour, 3 hours and 5 hours. The results showed that the peroxide value increased with increasing oxygen flow rate and ozonation time. The highest peroxide value was obtained at a flow rate of 0.7 L/minute for 5 hours, namely 332.03 mg Eq/kg Sumbawa oil. Increased by 282.71 mg Eq/kg; the peroxide figure for Sumbawa oil without ozonation was 49.32 mg Eq/kg.
