AIMS:  To quantify the effect of chewing gum on orthodontic outcome in adolescent patients.
SUBJECTS AND METHOD:  Six hundred and three adolescent patients (222 males, 381 females) aged 12 to 16 years within nine hospital orthodontic departments across the South West of England, who had completed treatment and for whom Peer Assessment Rating (PAR) scores were available. This was a multi-centred randomised controlled trial with two parallel groups, allocated to chew gum as a primary analgesic following fixed appliance placement and adjustment, or asked not to chew gum and use ibuprofen as required (control). Ethical approval was obtained. Data from the written records for every visit from initial bond-up to debond was collated and analysed using parametric tests and generalised linear modelling The primary measures of orthodontic outcome investigated were: duration of treatment, number of visits and reduction in PAR score, in addition to a secondary outcome namely the number, location and timing of attachment failure.
RESULTS:  The use of chewing gum for pain relief had no significant effect on any of the measures of outcome (α = 0.05). Average treatment time was 18.3 months (range 6.4 ~ 46.3 months). The mode total number of visits was nine (range 4~36 visits). The mean PAR score reduction was 83.5 per cent. There was no significant effect of chewing gum on breakages in either the upper (χ2 = 14.17, P = 0.29) or lower arch (χ2 = 11.27, P = 0.66).
CONCLUSION:  Advising adolescent patients to chew gum had no clinically significant effect on the outcome of fixed appliance therapy
