OBJECTIVE:

To compare the effects of bio-oxidative ozone application with occlusal splints in temporomandibular disorder (TMD) patients with pain.

 

METHODS:

Forty participants were selected after the diagnosis of TMD and randomly divided into two groups: ozone group (OG, n = 20) and occlusal splint group (OCSG, n = 20). Ozone was applied to patients three times per week, for a total of six sessions. Patients in the OCSG were instructed to use occlusal splints every night over a period of four weeks.

 

RESULTS:

Mandibular movements showed significant differences for the time factor in OG and OCSG. Pressure pain thresholds of the temporal and masseter muscles at follow-up were significantly higher in the OCSG group. Both treatments statistically decreased the visual analog scale (VAS) scores. However, no statistically significant difference was observed between groups after the application of treatments.

 

DISCUSSION:

Occlusal splint treatment is still the gold treatment modality for objective pain relief in patients with TMD pain.

 

KEYWORDS:

Ozone; occlusal splints; orofacial pain; temporomandibular joint disorders

Dry eye, an age-related condition, is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance and tear film instability. Environmental factors are also often implicated in dry eye including exposure to pollutants, ultraviolet (UV) radiation and ozone as well as the chronic use of preserved eyedrops such as in the treatment of glaucoma. These factors increase oxidative stress and ocular surface inflammation. Here, we reviewed the cellular, animal and clinical studies that point to the role of oxidative stress in dry eye disease. The biomarkers used to indicate oxidative damage in ocular surface tissues include 8-hydroxy-2 deoxyguanosine (8-OHdG), 4-hydroxynonenal (HNE) and malondialdehyde (MDD). Antioxidative defences in the ocular surface occur in the form of tear proteins such as lactoferrin and S100A proteins, and enzymes such as superoxide dismutase (SOD), peroxidase, catalase and mitochondrial oxidative enzymes. An imbalance between the level of reactive oxygen species (ROS) and the action of protective enzymes will lead to oxidative damage, and possibly inflammation. A small number of interventional studies suggest that oxidative stress may be directly targeted in topical therapy of dry eye treatment. For example, in vitro studies suggest that L-carnitine and pterostilbene, a blueberry component may reduce oxidative stress, and in animal studies, alpha-lipoic acid (ALP) and selenoprotein P may be helpful. Examples of treatments used in clinical trials include vitamin B12 eyedrops and iodide iontophoresis. With recent emphasis on ageing medicine and preventive holistic health, as well as the role of environmental science, research on oxidative stress in the ocular surface is likely to have increasing impact in the coming years.

The use of ozone (O3) gas as a therapy in alternative medicine has attracted skepticism due to its unstable molecular structure. However, copious volumes of research have provided evidence that O3's dynamic resonance structures facilitate physiological interactions useful in treating a myriad of pathologies. Specifically, O3 therapy induces moderate oxidative stress when interacting with lipids. This interaction increases endogenous production of antioxidants, local perfusion, and oxygen delivery, as well as enhances immune responses. We have conducted a comprehensive review of O3 therapy, investigating its contraindications, routes and concentrations of administration, mechanisms of action, disinfectant properties in various microorganisms, and its medicinal use in different pathologies. We explore the therapeutic value of O3 in pathologies of the cardiovascular system, gastrointestinal tract, genitourinary system, central nervous system, head and neck, musculoskeletal, subcutaneous tissue, and peripheral vascular disease. Despite compelling evidence, further studies are essential to mark it as a viable and quintessential treatment option in medicine.

 

Introduction

Ozone (O3) gas was discovered in the 1840s, and soon after that, the scientific community began to expand past the notion that it was just another gas of the Earth's atmosphere. Though the migration of O3 into the medical field has taken a circuitous road since the 19th century, its medicinal value is currently controversial despite compelling research. O3 is highly water-soluble inorganic molecule composed of three oxygen molecules. O3's inherently unstable molecular structure, due to the nature of its mesomeric states, tends to make it difficult to obtain high concentrations. O3 will often experience transient reactions with itself or water. Thus, it was initially problematic to achieve desired levels and even more difficult is to assess the therapeutic effects of such a transient state. These mesomeric states create a conundrum within the scientific community. A divide has formed between those who believe the volatile nature of these mesomeric states can foster positive responses and those who are wary of its seemingly dangerous effects.

Despite suspicions, a multitude of O3 therapies have shown substantial benefits that span a large variety of acute and chronic ailments. O3 is currently prevalent in dentistry to treat diseases of the jaw. O3 has also proven itself beneficial as a disinfectant for drinking water and sterilization of medical instruments. The function of O3 shares similarities to that of a prodrug, as it is modified upon reacting with molecules to create more active substrates, thus stimulating an endogenous cascade of responses. On the other hand, it is hard to classify O3 as simply a prodrug, due to its capability to directly interact with phospholipids, lipoproteins, cell envelopes of bacteria, and viral capsids. The physiology of these biological responses is herein discussed.

Despite the various benefits, O3 toxicity and clinical utility depends on the concentration and administration to the appropriate site. One of the major contraindications of O3 therapy is lung inhalation. O3 therapy significantly increases airway resistance without changing the compliance or elastic characteristics of the lung. Additionally, direct contact of O3 with the eyes and lungs is contraindicated because of the low antioxidant capabilities in these specific locations.
