A small informative presentation on the uses of ozone therapy in dentistry.

Ozone Therapy in Dentistry

  1. 1. Introduction • Ozone is known to us as a molecule present in the atmosphere which protects us from radiation. It also binds to the pollutants presents, hence used to measure pollution levels. • This is the job of ozone, to be nature’s filter of “bad” particles.
  2. 2. WHAT IS OZONE ? • • • • • Ozone (O3) is a triatomic molecule. 10-fold more soluble in water than oxygen. Ozone is not a radical molecule It is the third most potent oxidant. It also has the capacity to stimulate blood circulation and the immune response.
  3. 3. How is ozone produced ? Ozone is naturally formed by the sun and lightning in storms.
  4. 4. Ozone Generators
  5. 5. Forms of ozone used • Ozone gas. • Ozonated water. • Ozonated olive oil. These can be used singly or in combination
  6. 6. HOW DOES OZONE THERAPY WORK ? • Ozone, when introduced into the living system, creates what is called a "transient oxidative burst". The infective microorganisms have no natural defense against the reaction, and, as a result, are overstressed and die. Thus, Ozone disinfects the area treated. • This "oxidative burst" also includes a multitude of natural biochemical and physiological reactions. These reactions include better blood flow, enhanced immune response, and a more rapid healing response.
  7. 7. CAN YOU BE ALLERGIC TO OZONE ? • No, Ozone is just an energized form of oxygen.
  8. 8. Safety from ozone • Due to safety concerns, O3 gas was not recommended for intra-oral use earlier. • With the development of a foot pedal activated dental handpiece with a suction feature, O3 gas can now be used safely in situations where diffusion is an important factor.
  9. 9. Primary Pits & Fissures Caries Proximal Caries Lesions – As a general rule, in non-cavitated low speed onset lesions, a non-invasive protocol should be used first. In cavitated lesions, restoration is a must. – The tooth is treated with ozone can completely stop all caries activity and in initial lesion even reverse the damage and allow remineralization.
  10. 10. Hyper-Sensitive Teeth – Non-carious hypersensitivity is due to many contributing factors among which are erosion, bite pressure, recessed gum, etc. – After elimination of the cause(s), ozone application might alleviate almost instantly the pain felt by the patients from hypersensitive teeth in most cases. – Apply ozone for 40-60 sec on sensitive areas then a remineralizing agent. Repeat if necessary.
  11. 11. Root Canal Therapy – Ozone is highly indicated in root canal therapy due to its strong disinfection property and absence of cytotoxicity at the recommended concentration and form. – The ozonated air can get to the narrowest places in the canal and peri-apical region where conventional liquids may not be able to reach, disinfect the area and accelerate healing. – Also it reduces the requirement of antibiotics as the region is disinfected locally. – Ozonated oil can be used as a root canal dressing.

  13. 13. Periodontal Therapy – Gingival and Periodontal diseases represent a major concern both in dentistry and medicine. – The majority of the contributing factors and causes in the etiology of these diseases are reduced or treated with ozone. – Using ozonated water generously irrigate the affected area during and after scaling, root surface planning, and non-surgical pocket curettage. – Fill the pockets with ozonized olive oil using a blunt 25G needle or any other appropriate tip. Repeat once a week till seen fit.

  15. 15. TMJ Peri-Articular Ozone Gas Injection - Trigger Points – The biostimulation and anti-inflammatory effects of ozone help in the management of articulation inflammatory diseases and muscular trigger points. – Chronic oxidative stress and elevated levels of pro-inflammatory cytokines are commonly found in these skeletal chronic inflammations where ozone gas infiltration can contribute in stimulating the anti-oxidant defense mechanism and in balancing the immune response by modulating the production of cytokines

  17. 17. Post-Extraction – After final debridement of the socket, irrigate with copious amounts of ozonated water and then use gauze imbibed with ozonated water to compress the extraction site. Before retiring the patient, fill the socket with ozonized oil and cover it with gauze, it improves healing and prevents infection.

  19. 19. Peri-Implantitis – Peri-implantitis is very bothering to both the dentist and the patient. – Ozone can play an important role and be used as gas or in aqueous form. – Ozonated water can also be used as an irrigant during debridement and curettage. – Also advise the patient to apply ozonized oil on the affected area 3-4 times/day.

  21. 21. Crowns & Bridges - Veneers – A common occurrence we sometimes see during the temporization phase in crowns, inlays/onlays and veneers procedures is hypersensitivity. – Many factors might contribute in this event, one of which is the presence of bacteria left inside the opened dentinal tubules during preparation. It is paramount to remove the smear layer and disinfect the prepared teeth before temporization and before seating of the final restoration.

  23. 23. Soft Tissue Lesions – All kinds of infectious, inflammatory, traumatic, burns, wounds, soft tissue lesions respond very well to topical ozone treatment. – The infected area is sealed with a PVC or silicone cap and ozone gas applied for 1-2 minutes. In larger areas aqueous ozone is also used. Repeat if necessary. – In case of cyst fistula, insert a plastic needle slowly in the passage of the fistula and inject 12 cc of ozone gas. – In many instances, daily at home application of ozonized olive oil is required.
  24. 24. EFFECT OF OZONE THERAPY ON SOFT TISSUE LESIONS Herpetic lesion treated with 2 min application of ozone gas. Picture taken 40 min post ozone application.
  25. 25. Whitening with Ozone – Due to the strong oxidation power of ozone, researchers started looking on the ability of ozone to whiten teeth. – The results so far are promising.
  26. 26. Conclusion • Modern dentistry is all about non/minimal invasive dentistry. Ozone therapy in the present stage is reducing caries activity, improving periodontal health, and also improving the healing time of oral lesions and wounds. Ozone therapy is bound to revolutionize the way dentistry is going to be practiced in the future.
