Objective: To determine the psychometric properties of a pre-existing orthodontic satisfaction questionnaire and to assess patient satisfaction of their orthodontic treatment. Design: Psychometric assessment of a pre-existing orthodontic satisfaction questionnaire. Setting: Two sites at King’s College Hospital NHS Foundation Trust. Participants: Individuals aged 12–15 years who had completed fixed orthodontic treatment. Methods: An expert panel assessed a pre-existing orthodontic treatment satisfaction questionnaire for validity and readability. As a result, revisions were made to the questionnaire and it was distributed to 103 participants aged 12–15 years, on completion of their fixed orthodontic treatment (T1). Test–retest reliability of the questionnaire was assessed through completion of a second questionnaire by 17 participants, at a two-week interval (T2). The questionnaire was assessed for reliability using item-total correlations (I-TC) and Cronbach’s alpha. Factor analysis allowed exploration of the underlying factor structure of the questionnaire. Test–retest reliability was assessed using Cohen’s kappa coefficient. Multiple regression analysis was used to find out the significant demographic variables that predicts the satisfaction level of treatment. Results: Following validity and readability assessment by the expert panel, the questionnaire was revised. Eleven items were removed following item analysis (with I-TC ⩽ 0.3). Factor analysis was deemed uninterpretable. The overall scale demonstrated greater reliability than the underlying sub-scales. Therefore, the sub-scales were removed, resulting in one scale which assessed overall orthodontic satisfaction, comprising 37 items, with a Cronbach alpha of 0.92. The test–retest reliability of the revised 37-item scale was deemed to be poor (kappa coefficient = 0.39). Multiple regression analysis identified ethnicity as a significant predictor of orthodontic treatment satisfaction ( P = 0.01). Conclusion: This study provides a valid measure to assess orthodontic treatment satisfaction for use in a UK population aged 12–15 years on completion of fixed orthodontic treatment.

The aim of this article was to establish the geographic origin and the proportion of full length and research articles in each of four journals over a five-year period: Angle Orthodontist (AO), American Journal of Orthodontics (AJODO), European Journal of Orthodontics (EJO) and Journal of Orthodontics (JO). CPD/Clinical Relevance: Evidence-based practice is crucial in the management of our patients. Journals remain a conventional way of disseminating scientific literature to a global audience. When considering articles for publication, are certain characteristics thought of more favourably, such as article type (eg research), or geographic origin? This, in turn, may influence the type of articles readers are exposed to, and the journal that authors submit to, consequently posing barriers to a truly global orthodontic community.

A case is presented of a 14-year-old male patient being treated with a fixed orthodontic appliance who presented with a persistent upper lip swelling. The patient was experiencing discomfort from the appliance and the appliance was debonded. A diagnosis of orofacial granulomatosis was established and the patient was managed carefully with a cinnamon- and benzoate-free diet leading to resolution of the swelling. Orofacial granulomatosis is a rare condition and its presentation, diagnosis, and management are discussed. CPD/Clinical Relevance: Orthodontists should be aware of the presentation of orofacial granulomatosis and the possible challenges associated with managing these patients.
