Study information
Scientific title
Chewing gum and orthodontic pain: a randomised interventional and observational cohort study
Acronym
Study hypothesis
The null hypothesis in this intention to treat study is that there is no difference between the use of ibuprofen and sugar-free chewing gum in the relief of orthodontic pain in the 3 days following the fitting and then subsequent adjustment of orthodontic fixed appliances. The secondary outcome measure is bracket or wire failure. In addition patient anxiety will be measured following brace fitting and subsequent adjustment as anxiety may affect the perception of pain.
