Ozone therapy in postgraduate theses in Egypt: Systematic review

Background: systematic reviews of the studies published in the major medical data bases have not shown solid support for the use of ozone therapy. unpublished or grey literature,including postgraduate theses,may solve this controversy. objectives: to review the postgraduate theses published in egypt in order to assess the clinical safety and effectiveness of ozone therapy in specific medical conditions. methods: the databases of the egyptian universities' library consortium and the databases of each university were searched for postgraduate theses that evaluated ozone therapy as an intervention for any disease or condition in any age group,compared with any or no other intervention and published before september 2010. results: a total of 28 quasi trials were included. the theses did not report any safety issues in terms of ozone therapy. with respect to its effectiveness,the studies suggested some benefits of ozone in the treatment of dental infection and recovery,musculoskeletal disorders,diabetes mellitus,chronic diseases,and obstetrics and gynaecology. however,the number of studies included was small and they were of limited quality. conclusion: there is insufficient evidence to recommend the use of ozone in the treatment of dental infections,in facilitating faster dental recovery after extraction or implantation,in diabetes mellitus,musculoskeletal disorders,or obstetrics and gynaecology. © 2013 egyptian public health association.
