ABSTRACT Oxygen-ozone therapy, initially started as an empirical approach, has now reached a stage where most of the biological mechanisms of action of ozone have been clarified, showing that they are in the realm of orthodox biochemistry, physiology and pharmacology. Here we have reviewed a few relevant clinical applications and have shown that ozone therapy is particularly useful in cardiovascular disorders and tissue ischemia. In chronic viral infections, it is unable to eliminate the viremia but it may display supportive help by stimulating the immune system. Recently, its use has been successfully extended to the herniated disk pathology and therapy of primary caries in children.

    ABSTRACT: The aim of this study is to evaluate the effect of ozone and fluoride varnish on occlusal caries in primary molars in a split-mouth study. Caries risk was estimated by treating Public Dental Health Service dentists. Children with occlusal caries with Ekstrand index scores ≤3 (VI ≤3) were included. Selection of caries lesions was discontinued for ethical reasons due to non-acceptable clinical results during the follow-up. In the continued evaluation pairs of teeth with non-cavitated caries lesions, Ekstrand score ≤2a (VI ≤2) were selected. Fifty pairs of carious primary molars were included, 18 boys and 15 girls (mean 4.7 years, range 3-8). At baseline, the lesions were assessed by visual inspection (VI) and laser-induced fluorescence (LF), in each pair to treatment with 40 s ozone (HealOzone(TM), 2,100 ppm) or fluoride varnish Duraphat®. The treatments and evaluations were repeated at 3, 6 9 months and evaluations only at 12 months. Medium-high caries risk was observed in VI ≤3 children and low-medium risk in VI ≤2a children. In the 15 pairs VI ≤3 lesions, 8 treated with ozone and 9 with fluoride progressed to failure. In the 35 pairs VI ≤2a lesions, one lesion failed. Median baseline LF values in the VI ≤3 group were 76 and 69, for ozone and fluoride lesions, respectively, and 21 and 19 in the VI ≤2a group. At 12 months, LF values in the VI ≤2a group were 15 and 18. No improvement or difference in LF values was found over time between the caries lesions treated with ozone or fluoride. Neither ozone nor fluoride varnish treatments stopped the progression of caries in cavitated lesions. In low and medium caries risk children, non-cavitated lesions following both treatments showed slight or no progression. The use of ozone or fluoride varnish treatments in this regime as caries preventive method, added to the daily use of fluoridated toothpaste, to arrest caries progression in primary molars must therefore be questioned.

    ABSTRACT: The objective of this study was to evaluate the role of ozone therapy (as a part of a comprehensive approach) with its different techniques in the management of diabetic foot problems and chronic nonhealing wounds. The study design included a case series study, with review of the literature. Researchers used an ozone therapy unit, a Navy Diving and Hyperbaric Medicine Institute, and Ozone Therapy Unit, at the Armed Forces Hospital, in Alexandria, Egypt. All patients with diabetic foot problems and chronic nonhealing wounds were treated with ozone therapy from August 2006 to August 2009. Full history and clinical examination to identify diagnosis, and determine therapeutic comprehensive approaches including ozone therapy treatment protocols. Observation notes on the practice of ozone techniques, progress of diseases and outcome were accurately documented. Data were reviewed against best practice described in the literature. We observed overall successful treatments in 87% (46% of them complete healing) of patients treated with ozone. We reported the general and topical effects of ozone correlated to the technique used. The present study offers the clinical evidence which supports and recommends the use of ozone in diabetic foot and chronic nonhealing wounds. Cooperation between surgeon and ozone therapist is a must for successful outcomes. Randomized controlled trials should be performed as an essential method for accurately proving the reliability, efficacy and possible side effects of ozone therapy, and to introduce ozone to the world of surgeons and clinicians.

    ABSTRACT: This study aimed to compare the antimicrobial efficacy of low temperature atmospheric pressure plasma (LTAPP) design and gaseous ozone delivery system with 2.5% NaOCl on E.faecalis in root canal walls and dentine tubules. The samples were divided into LTAPP (n=12), ozone (n=12), NaOCl (positive control, n=12); and saline (negative control, n=6) groups. Microbial samples were collected using paper points and dentin chips from root canals. Antimicrobial efficacy was assessed by counting the Colony Forming Units of E. faecalis before and after each irrigation protocol. Data were analyzed using Kruskall-Wallis, Wilcoxon signed-rank, Friedman and Bonferroni t (Dunn's test) tests (P=0.05). The microbial sampling with paper points showed antibacterial efficacy of NaOCl, LTAPP, ozone, and saline in descending order, respectively (P<0.05). The microbial sampling with dentin chips demonstrated a superior efficacy of LTAPP compared to NaOCl in the middle third (P<0.05), while both had similar effects in coronal and apical thirds (P>0.05). NaOCl and LTAPP were better than ozone at the coronal and middle parts of the root canals (P<0.05). These findings led us to suggest that LTAPP, which has no thermal and chemical effects, may be of great aid in endodontic treatment. This article is protected by copyright. All rights reserved.
