OBJECTIVES: Medication-related osteonecrosis of the jaws (MRONJ) is an extremely therapy-resistant disease involving the jaws especially following bisphosphonate treatment. Bisphosphonates accumulate in bone in concentrations sufficient to be directly toxic to the oral epithelium. Current therapeutic options are inadequate for the prevention and treatment of MRONJ. The aim of this study was to investigate effects of ozone gas plasma therapy on wound healing in bisphosphonate-applied human fibroblasts.

MATERIAL AND METHODS: Human primary gingival fibroblasts were cultured. Cytotoxic concentrations (IC50) of bisphosphonates (pamidronate (PAM), alendronate (ALN), and zoledronate (ZOL)) were determined by MTT test. A 60 μg/μl for 30 s of ozone gas plasma application was performed to all experimental culture flasks after drug treatment at 24-h intervals as 3 s/cm(2). Genotoxic damages were evaluated by comet assay and wound healing was determined by in vitro scratch assay.

RESULTS: PAM, ALN, and ZOL applications caused genotoxic damage on primary human gingival fibroblast DNA. Ozone gas plasma therapy significantly decreased the genotoxic damage (p < 0.05), and this application provided 25, 29, and 27% less genotoxic damage in order of ALN, PAM, and ZOL groups. Ozone gas plasma therapy significantly increased wound healing rates both in postsurgical 24th and 48th hours for all doses of experimental drug groups (p < 0.05).

CONCLUSION: The ozone gas plasma application decreased genotoxic damage effect of bisphosphonate usage while improved the wound closure rate on human gingival fibroblasts.

CLINICAL RELEVANCE: Ozone gas plasma therapy may be helpful in prevention of gingival healing delay in MRONJ pathogenesis especially when applied simultaneously with surgical intervention.

OBJECTIVES: To evaluate the effect of bio-oxidative ozone application at the points of greatest pain in patients with chronic masticatory muscle pain.

 

METHODS: A total number of 40 (40 women, with a mean age of 31.7) were selected after the diagnosis of myofacial pain dysfunction syndrome according to the Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD). The patients were randomly divided into two groups; patients received the ozone therapy at the point of greatest pain, ozone group (n = 20); patients received the sham ozone therapy at the point of greatest pain, placebo group (n = 20). Ozone and placebo were applied three times per week, for a total of 6 sessions. Mandibular movements were examined, masticator muscles tenderness were assessed and Pressure Pain Threshold (PPT) values were obtained. Subjective pain levels were evaluated using Visual Analogue Scale (VAS). These assessments were performed at baseline, 1 month and 3 months.

 

RESULTS: Ozono therapy decreased pain intensity and increased PPT values significantly from baseline to 1 monthand 3 months in Ozone Group (OG) compared with Placebo Group (PG). PPTs of the temporal (OG=24,85±6,65, PG=20,65±5,43, p=.035) and masseter (OG=19,03±6,42, PG=14,23±2,95, p=.007) muscles at 3 months control (T2) were significantly higher in the OG group. PPT value of the lateral pole (LP) was also significantly higher at T2 in the OG group (OG=21,25±8,43, PG=15,35±4,18, p=.012). Mandibular movements did not show significant differences between treatment groups except right lateral excursion (RLE) values at T2 (OG=8,90±1,77, PG=6,85±2,41, p=.003), however, OG demonstrated significanty better results over time. Overall improvements in VAS scores from baseline to 3 months were: OG 67.7%; PG 48,4%.

 

CONCLUSION: Although ozone therapy can be accepted as an alternative treatment modality in the management of masticatory muscle pain, sham ozone therapy (placebo) showed significant improvements in the tested parameters. This article is protected by copyright. All rights reserved.

Abstract

 

The panniculosis or edematous fibrosclerotic panniculopathy (PEFS), commonly called cellulite is a subcutaneous adipose disease that afflicts the vast majority of women at all ages. PEFS is framed as a subcutaneous adipose suffering from venous and lymphatic stasis whose etiology is multifactorial. Many others are the implications and clinical relapses of diseases of inflammatory or autoimmune basis that determine disease states with involvement of the patient’s general conditions. The oxygen-ozone therapy, thanks to its abilities of improving the rheological properties of the microcirculation, immuno-modulating and anti-inflammatory abnormalities, arises as adjuvant and is a valid method, which is also an alternative compared to conventional protocols.
