Evidence-based orthodontics has developed rapidly in recent years, but the lack of a good quality, clinical evidence base is a problem for orthodontic practice. All orthodontists should keep the concept of evidence-based medicine in mind during patient-oriented practice. This would help us to improve our practice and to make the best clinical decisions.
Having searched The Cochrane Library (Issue 4, 2005), we found: fluoride can reduce the occurrence and severity of white spot lesions; removal of premature contacts of the primary teeth can prevent posterior crossbite; expanding the top teeth can decrease the risk of a posterior crossbite; CSF may help retaining teeth; clear overlay retainer may settle teeth quicker than Hawley retainer; adhesives for fixed orthodontic brackets is still in dispute.
