18 ORTHO NEWS Ortho Tribune United Kingdom Edition | 1/2017 Obesity may infl uence response to orthodontic treatment in minors By DTI LONDON, UK: In Western countries like the UK, it is estimated that almost every third child is now AD overweight or obese. At the same time, an increasing number of children are receiving fi xed braces to correct malocclusions at an early age. A new study conducted by re- searchers at King’s College London Dental Institute and published in the Journal of Dental Research has now indicated that the response to this particular type of treatment can signifi cantly vary depending on a child’s body weight. In the cohort study, the re- searchers followed a number of register for FREE – education everywhere and anytime – live and interactive webinars – a focused discussion forum – free membership – no travel costs – no time away from the practice – interaction with colleagues and experts across the globe – a growing database of scientific articles and case reports – ADA CERP-recognized credit administration www.OTStudyClub.com Ortho Tribune Study Club Join the largest educational network in orthodontics!

During the examina- tions, it was found that those patients who were obese had a sig- nifi cantly increased rate of initial tooth movement and required less time to achieve tooth align- ment compared with normal- weight patients. The researchers also noticed increased levels of infl ammatory biomarkers in the gingival tissue of obese patients prior to ortho- dontic treatment. The fi rst of its kind to study the relation between obesity and orthodontic tooth movement, it demonstrates that the condition in adolescent patients infl uences the supporting tissue around the tooth, the researchers said, and this could have important impli- cations for orthodontic treatment outcome in obese patients over both the short and long term. Levels of obesity have in- creased signifi cantly throughout all age groups in Western societies in the last two decades, and it has been linked to multiple chronic diseases, including periodontal infl ammation. In a 2015/2016 evaluation, Public Health England found that 14 per cent of one million schoolchildren in the UK were classifi ed as overweight and almost 20 per cent as obese. The King’s study, titled “Im- pact of obesity on orthodontic tooth movement in adolescents: A prospective clinical cohort study”, was published online on 23 January in the Journal of Dental Research.
