Ozone Therapy in the Dentistry
The materials presented in this section are kindly provided by our Lebanese partner Dr. Fadi Sabbah, DDS.
The use of ozone in dentistry is gaining its place in every day's dental practice and is used in almost all dental applications.
The undisputed disinfection power of ozone over other antiseptics makes the use of ozone in dentistry a very good alternative and/or an additional disinfectant to standard antiseptics. Minimally Invasive Dentistry is now the new Standard of Care in all disciplines of dentistry, most importantly in preventive and operative dentistry.
So far, arresting and reversing the process of tooth caries without invasive treatment are unpredictable and rely very much on patient's compliance.
The undisputed disinfection power of ozone over other antiseptics makes the use of ozone in dentistry a very good alternative and/or an additional disinfectant to standard antiseptics. Minimally Invasive Dentistry is now the new Standard of Care in all disciplines of dentistry, most importantly in preventive and operative dentistry.
So far, arresting and reversing the process of tooth caries without invasive treatment are unpredictable and rely very much on patient's compliance.
Recent research and clinical studies on the use of ozone in treating early tooth caries without cavitations are very promising and are showing that it is now possible to arrest and reverse these lesions in a predictable and repeatable way without invasive intervention. These findings are establishing a paradigm shift, a revolution in dentistry.
Due to safety concerns, O3 gas was not recommended for intra-oral use. Only dissolved ozone in water and ozonated oils were and are still commonly used in different fields of dentistry. With the development of a footpedal-activated dental handpiece with a suction feature, O3 gas can now be used safely in situations where diffusion is an important factor, i.e.: dental hard tissues more information.

Clinical Procedures
1. Operative Dentistry
After a comprehensive diagnosis and caries risks assessment, depending on your preferred approach and management, you should be able to classify the caries lesions according to a severity index upon which you would be able to make a clinical judgment on how to proceed with treatment.

1.2. Proximal Caries Lesions
Proximal caries lesions are readily diagnosed with Bite-Wing X-Rays unlike occlusal ones. Depending on the depth and speed onset of the lesions, a decision is made on whether to open and access the lesion or to use a non-invasive treatment.
As a general rule, in non-cavitated low speed onset lesions confined in enamel or at the EDJ, a non-invasive protocol should be used first. If the lesion extends in dentin, the final judgment should be based on the caries risks assessment of the patient. In cavitated lesions, restoration is a must.
Follow the same guidelines as described in the pits and fissures protocol.

1.4. Hyper-Sensitive Teeth
Non-carious hypersensitivity is due to many contributing factors among which are erosion, abfraction, bite pressure, recessed gum, etc. After final diagnosis and elimination of the cause(s), ozone application might alleviate almost instantly the pain felt by the patients from hypersensitive teeth in some cases.
Apply ozone for 40-60 sec on sensitive areas then a remineralizing agent. Repeat if necessary.

2. Root Canal Therapy - Peri-Apical Lesions
Ozone is highly indicated in root canal therapy due to its strong disinfection property and absence of cytotoxicity as well as other negative side effects at the recommended used concentration and form (gas or dissolved in water). Ozonized oils can also be used as a temporary canal(s) dressing in infected necrotic cases. In peri-apical lesions, ozone gas infiltration contributes in the non-surgical management of these lesions.
2.1. Vital Root Canal Therapy
After final shaping and cleaning of the canal(s), adapt a 25-27 G needle on the delivering central tip of the handpiece, making sure not to obliterate the free gas circulation inside the round tapered housing. Cut a piece of PVC or silicone tube according to the clinical situation in order to seal the access cavity with the needle inside the canal. The needle should not block the intra-canal gas circulation towards the canal orifice.
Fill the canal with saline or distilled water and apply ozone for 2-3 minutes per canal at 5µg/ml, 0.5 - 1 L/min flow rate.
During the canal shaping and irrigation, ozonated water can be used as a disinfectant and irrigant. Use Acquazone ozonated water column to easily prepare ozonated water for the entire root canal procedure. Irrigate at demand with large volumes.

2.2. Necrotic Root Canal Therapy
In some situations, there is a need to disinfect the root canal system with a temporary dressing until the symptoms are relieved and the canal(s) ready to be filled. Follow the same protocol as above and use ozonized olive oils as a temporary disinfection dressing. Fill a 1cc disposable syringe with the oil and adapt a 25G needle. Insert the needle as deep as possible inside the canal and inject slowly while retrieving the needle slowly out of the canal. You can also use a Lentulo to fill the canal with the ozonized oil.
2.3. Peri-Apical Lesions
Local anesthesia is recommended in this procedure.
In maxillary peri-apical lesions, ozone infiltration is performed the same way you give a local anesthetic injection on the buccal side. Depending on the size and severity of the lesion, the concentration varies between 5 and 10 µg/ml at a volume of 1-3 cc. Inject the gas very slowly as close as possible to the site of the lesion. Repeat the infiltration once a week until resolution of the symptoms.
In mandibular peri-apical lesions, the use of an intra-osseous needle to deliver the ozone gas right into the bone is indicated. Use your preferred technique to perforate the cortical bone, making sure to stay away of the alveolar inferior canal and mental nerve. The access point is usually 2-3 mm under the free gingival level where the cortical bone is easily perforated. Inject very slowly as described above.

3. 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 in all its application forms (gas, water, oil).
The beneficial biological effects of ozone, its anti-microbial activity, oxidation of bio-molecules precursors and microbial toxins implicated in periodontal diseases and its healing and tissue regeneration properties, make the use of ozone well indicated in all stages of gingival and periodontal diseases.
According to the clinical case, different applications modalities are available using ozone gas, irrigation with ozonated water and in-office use of ozonized oil as well as home use.

3.1. Gas application via a customized thermoformed dental appliance
Prepare a suckdown thermoformed hard or medium-soft dental appliance extending 2-3 mm beyond the affected gingival area, leaving a free space for gas circulation. Attach 2 ports for the gas inlet and outlet respectively at the distal and mesial of the treatment area. Reline the edges of the appliance with light or medium body silicone.
Light-cured dam can also be applied as an extra safety precaution to completely seal the borders. Attach the ports to the generator and the suction pump. This procedure will treat both hard and soft tissues of the affected area. You can always use the PVC or silicone cap and treat individually all the indicated areas in difficult situations where such an appliance is hard to use or uncomfortable to the patient.

3.2. Irrigation with Ozonated Water
Prepare the ozonated water using Acquazone and generously irrigate the affected area during and after scaling, root surface planning, and non-surgical pocket curettage.
3.3. In-office and Home Use of Ozonized Olive Oil
After in-office treatment with ozone gas or ozonated water, fill the pockets with ozonized olive oil using a blunt 25G needle or any other appropriate tip. Give the patient for home use some of the oils and instruct him/her on proper application. Repeat the in-office ozonized oil application once a week.

4. Post-Extractions - Surgery
In dental/oral surgery, the use of ozone is indicated during the surgical intervention as well as post-surgery as a topical disinfectant and healing agent. In these procedures, the use of ozone gas is not convenient due to the inability to properly seal the treated area. Ozonated water and oils are therefore the forms of application.
4.1. 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.
4.2. Post-Extraction Alveolitis
After thorough assessment, remove the necrotic plug and debris from the extraction site, irrigate with large amounts of ozonated water then fill the alveoli with ozonized oil. Antibiotic coverage may be indicated. Instruct the patient to apply ozonized oil 3-4 times a day until total healing.
4.3. Surgical Procedures
Ozonated water can be used as an irrigant during the surgical procedure and/or as a final surgical site lavage. Cover the sutures with a thin layer of ozonized oil and instruct the patient to apply the oil 3-4 times a day.
4.4. Peri-Implantitis
Peri-implantitis is very bothering to both the dentist and the patient. After thorough assessment and if a decision is taken to salvage the case, different modes of therapy are used in order to save the implant from total loss. Laser and/or manual debridement along with antiseptic solutions and topical anti-microbial medicines are commonly performed with a varying degree of success. Ozone can play an important role and be used as gas or in aqueous form. Cut an appropriate length of PVC or silicone cap and cover fully the abutment. In case the crown is still present, it is advisable to remove it for proper sealing of the abutment and the gingival borders around the implant. Ozone gas infiltrations are also helpful in this situation. Ozonated water can be used as an irrigant during debridement and curettage. Advise the patient to apply ozonized oil on the treated area 3-4 times/day.

5. Crowns & Bridges - Veneers - Removable Dentures
5.1. 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.
The black stain that we see under the temporaries, mainly in the shrink-wrap veneers temporization technique is due to the presence of bacteria. The use of ozone gas to both disintegrate the smear layer and disinfect the prepared teeth is highly recommended (Fig. 1 - 2). The use of Air Abrasion before ozone is an advantage to completely remove microscopic debris and smear layer from the surface of the abutments and to leave a clean dentin for ozone disinfection.
Prior to final prosthesis cementation, clean the prepared teeth with Air Abrasion, disinfect with ozone gas and seat the prosthesis according to your preferred method. Please note that recent research and published articles show that ozone use do not affect the adhesive bonding procedures.
Use ozone gas to disinfect the prosthesis. Ozonated water can also be used.

5.2. Removable Dentures
A common occurrence found in full dentures wearers is denture stomatitis, mainly due to Candida albicans (Fig. 3). Whether white patches or erythematous forms, ozone use, mainly ozonated water and oil, is highly efficient in this situation and also helps in the cleaning and disinfection of the dentures acrylic material.
Prepare ozonated water using Acquazone and soak the denture(s) after thorough cleaning and removal of hard deposits. Imbibe a 5x5 cm gauze with the prepared ozonated water and apply on the affected areas. Refresh the gauze with ozonated water frequently or replace with a new one.
Remove excess water from the dentures and apply few drops of ozonized oil on the inside of the denture(s) and seat firmly.
Supply the patient with enough ozonized oil in a disposable syringe and home use instructions. For dentures sores and ulcers, see Soft Tissue Lesions section.

6. Soft Tissue Lesions
All kinds of infectious, inflammatory, traumatic, burns, wounds, soft tissue lesions respond very well to topical ozone treatment. As mentioned earlier, the beneficial biological effects of ozone and its disinfectant / healing properties make the use of ozone highly recommended in these situations.
Some practitioners even recommend intra or peri-infiltration of ozone gas in soft tissue carcinoma lesions.
The most soft tissue lesions encountered are herpes, aphthae, removable denture ulcers, traumatic wounds and cuts, cheilitis, cysts, Candida, etc.

6.1. Ozone Gas Application
Seal the affected area with a PVC or silicone cap and apply ozone gas for 1-2 minutes. Repeat if necessary.
In case of cyst fistula, insert a plastic needle slowly in the passage of the fistula and inject 1-2 cc of ozone gas. Anesthesia might be indicated in this procedure.

6.2. Ozonated Water Application
In situations of large traumatic wounds, burns and cuts, the combined use of ozone gas and ozonated water are indicated. For ozone gas, follow the above-mentioned protocol. Prepare the ozonated water using Acquazone ozonated water column and irrigate for 10 minutes the affected area. In case of supra-infected lesions, use a strong preparation of ozonated water. During the healing phase, a mild solution is more appropriate.
6.3. Ozonized Olive Oil Application
In many instances, the soft tissue lesions we frequently see can be managed with only the daily at home application of ozonized olive oil. These oils have a greater advantage over commonly used antiseptics and ointments due to their wide range of activities during all phases of the healing process. Supply the patient with enough ozonized oil in a disposable syringe and home use instructions.

7. Other Applications
7.1. Whitening with Ozone
Due to the strong oxidation power of ozone, researchers started looking on the ability of ozone to whiten teeth. Ongoing in-vitro works are studying the effects of long time exposure of ozone on the dental hard tissues and the pulp, as well as the application forms of ozone (gas - ozonated water), concentrations, etc.
The results so far are promising. The use of ozone in teeth whitening might revolutionize our present techniques.

7.2. Dental Unit Water Lines Disinfection - Office Tap Water Disinfection
Ozone use in city water disinfection and purification worldwide is recognized as the best city water treatment today. It becomes only logical to use ozone for the dental office tap water disinfection and purification.
The result is a clean, odorless, colorless tap water. Dental unit water lines are known to carry hard to remove biofilms inside them. Besides the bad odors coming out of these dirty water lines, the microbial biofilm may represent a source of infection to patients, especially who have a deficient immune system or the elderly. Many studies showed almost complete disintegration and elimination of dental unit water lines biofilms with ozonated water.

7.3. Instruments Cold Disinfection
Ozonated water can also be used as a cold disinfection solution for medical and dental instruments, as well as for cabinets countertop disinfection. Ozonated water can also be used as hands wash disinfectant solution, fiber optic tips, contact lenses, surgical loupes lenses, etc.
7.4. 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.

FAQ
You've brought up the problem of toxic impurities possibly containing in the delivered ozone/oxygen mixture. Is it really so important?
Every doctor using ozone therapy must be sure of its safety, thus there must be no doubt about the purity of delivered ozone/oxygen gas mixtures for medical use (they should be contaminant-free).
We consider this problem as very important. It is a fact that after approx. 100 hours of continuous operation owing to the electrochemical erosion of the ozonization chamber walls and electrodes some of available ozone generators deliver an ozone/oxygen gas mixture contaminated by impurities (calcium, aluminium, silicon, magnesium, copper etc) in concentrations considered as dangerous for the health that however can become evident even some months or years after the treatment. This claim is valid through the investigation of the upper layer taken from the ozonization chamber wall. There are only two possible reasons for the products which were found out on the wall:
Parenteral methods of ozone therapy are safe only if the ozone generator delivers pure contaminant-free medical ozone. Each medical ozone generator should be equipped with a filter for extra purification of oxygen used; purity of delivered ozone/oxygen gas mixtures should be guaranteed by the manufacturer through available test protocols, the same is about accuracy in maintaining the chosen ozone concentration (not worse than 10%) and great operation resource (durability) of ozonization chamber (without any decrease in the ozone production and without any change in ozone concentration accuracy) for at least 2000 hours of continuous operation.

This claim is valid through the investigation of the upper layer taken from the ozonization chamber wall. There are only two possible reasons for the products which were found out on the wall:
- Destruction of the electrodes (the discovered products are equivalent to the materials of electrodes);
- Fine contaminants possibly containing in oxygen which during the ozonolysis can be converted into toxic products.

What do you think about oxygen concentrators used as Oxygen Supply Systems for medical ozone generators?
There is no definite opinion at this point. Oxygen produced by these devices very seldom reaches the purity of 95% and higher, and we don not know whether the remaining 5% of content would not be dangerous due to electric synthesis in the ozonization chamber or interaction with ozone.
As you know, medical ozone generators require the use of medical oxygen referred to oxygen gas with guaranteed purity of 99,9% and higher. Anyways, we do not mind the use of oxygen concentrators for external i.e. local methods of ozone therapy.

Would you please explain a necessity for a built-in oxygen filter in medical ozone generators?
Our previous experience has shown that oxygen used can contain micro-quantities of technical oils, thus each ozone generator intended for medical use should be equipped with a filter for extra purification of oxygen that inhibits the introduction of technical oils possibly containing in oxygen into the ozonization chamber. During the ozonolysis technical oils can be converted into dangerous toxic products (fatty acids, ketones, aldehydes etc).
Within a long operation time of ozone generator great volumes of oxygen are conveyed through the ozonization chamber (within 100 hours of operation in case of saline ozonization at a flow-rate of 1 L/min approx. 6000 L of oxygen are conveyed through the ozonization chamber), the ozonization chamber gradually becomes covered with an oily layer, and the doctor cannot be sure of the quality of gas mixtures delivered, thus extra purification of oxygen through a filter at the inlet of ozone generator is a reasonable step.

Would you please explain the parameter "Range of selecting the dose of ozone"?
It is puzzling to us that some manufacturers of medical ozone generators use the parameter "Ozone production per 1 hour". This parameter was obviously taken from the ozone technology for water treatment, but in the medicine the ozone production should be adjustable at least per 1 min
How important is the accuracy of +/-5% … +/-10% in maintaining the chosen ozone concentration and the adjustable range 1 : 9950, as far as I know, recently these parameters have not been taken into consideration?
Before the New-Generation of medical ozone machines characterized by unique accuracy in maintaining the chosen ozone concentration and a uniquely wide range of ozone concentration adjustment, the doctors using ozone therapy were conditioned by the "traditional" types of ozone generator with very low accuracy in maintaining the chosen ozone concentration (worse than 40-50% as a rule) and a narrow adjustable range (1 : 15 - from 1 mg/l to 15 mg/l). The ozone concentration accuracy of +/-5% …+/-10% ensures a reasonable, predictable and dose-related therapy.
The high accuracy in maintaining the chosen ozone concentration allows using ozone like any other generally accepted medicine. That might have been one of the obstacles for wide spreading of ozone therapy. Nevertheless, all advantages of the Medozons machine do not influence its price, but this is a fact that there are many medical ozone generators on the market being much more expensive, but inferior in technical properties as compared with our machines.

The parameters "Range of ozone concentration adjustment 1:9950" and "Range of selecting the dose of ozone 0,25 … 10000" are not clear to us.
Would you please explain it?
Would you please explain it?
We can explain it with the Medozons-BM:
So, medical ozone generators of Medozons series are able to produce guaranteed pure medical ozone and dose it exactly, with regards to technical and medical features they are the best ones within Russia and have no analogies worldwide! We are sure that the above parameters today considered as unique tomorrow will be the new standards of ozone therapy.
- Range of delivered ozone concentrations (50…10 000) mcg/L. This parameter means that the machine is able to maintain the chosen ozone concentration within the available range with accuracy not worse than +/- 10%: 107 mcg/L or 5671 mcg/L.
- The parameter "Range of ozone concentration adjustment (1 : 9950)" means that the machine is able to provide 9950 values/gradations of ozone concentration with accuracy +/-10% that characterizes the depth of adjustment.
- The range of selecting the dose of ozone characterizes a wide range of ozone dosage adjustment from 0,25 mcg/L to 10000 mcg/L with accuracy +/-5%, at an ozone/oxygen flow-rate of 0,25 L/min adjustable by step 0,25 mcg; 0,5 L/min - 0,5 mcg; 1 L/min - 1 mcg.
So, medical ozone generators of Medozons series are able to produce guaranteed pure medical ozone and dose it exactly, with regards to technical and medical features they are the best ones within Russia and have no analogies worldwide! We are sure that the above parameters today considered as unique tomorrow will be the new standards of ozone therapy.
Would you please explain a necessity for an automated system of ozone-oxygen flow-rate adjustment, what about doing it manually by means of oxygen flow regulator? The use of fixed flow-rates (0,25; 0,5; 1,0 L/min) may limit the range of ozone applications.
Manually setting of oxygen flow-rate by means of regulator may induce a considerable decrease in ozone dosage accuracy (the dose of ozone = CO3 x O2/O3 flow-rate x treatment time) due to possible oxygen pressure fluctuations (in oxygen tank or any other oxygen supply system) or any change in gas tract resistance.
In medical ozone generators of Medozons series oxygen flow-rate delivered to the ozonization chamber is automatically stabilized at the given level regardless of influence from outside, the automated stabilization system of oxygen flow-rate is reliable even in case of considerable pressure fluctuations that ensures a dose-related therapy. The automatic gas supply system is tested by the manufacturer for accuracy in maintaining the chosen oxygen flow-rate. We are convinced that the fixed O2/O3 flow-rates do not limit, but widen the range of ozone applications, most of doctors perform ozone therapy at a flow-rate of 1 L/min, but using a flow-rate of 0,5 or 0,25 L/min it is possible to successfully perform intracavitary ozone therapy (in gynecology, urology etc).

How would you explain the fact that your ozone generators are not equipped with a measuring device to determine the delivered ozone concentration? To my mind, this can discredit the method of ozone therapy. From my own experience I know that at the starting point any medical ozone generator has the actual accuracy of delivered ozone concentration +/-40…+/-80%.
In medical ozone generators of Medozons series like Medozons-BM and BM-02 you can see a different functional principle of the ozonization chamber that ensures a wide range of ozone concentration adjustment (from 50 to 10000 mcg/L) with high accuracy in automatically maintaining the chosen ozone concentration not worse than +/- 10%, in fact, the actual accuracy tested by the manufacturer is not worse than +/- 5%. The attested accuracy is valid for at least the same time as the specified durability of the ozonization chamber before the scheduled prophylactic service (2000 hours of continuous operation or about 5 years of usage). The latest device Medozons-System has a built-in measurer of ozone concentratrions.
