British Orthodontic Society University Teachers Group Abstracts 2015 Presented at the World Federation of Orthodontists International Orthodontic Conference, London 2015 Cervical Vertebral Maturation (CVM) as a Valid Predictor of Growth. S. HOSNI*, G. BURNSIDE and J. E. HARRISON (School of Dentistry, The University of Liverpool, UK) Objectives: The primary objective was to assess if a correlation exists between CVM stage and statural height growth velocity. The secondary objective was to assess if a correlation exists between CVM stage and mandibular growth velocity. Design/Setting: A prospective longitudinal study undertaken at Liverpool University Dental Hospital. Subjects: Participants were aged between 8-18 years, of either gender and enrolled from those patients starting orthodontic treatment between 1/10/2012 and 31/01/2014. Methods: Standing height was measured every 6 weeks with subjects barefoot and in natural head position. CVM stage and mandibular growth (using the area of the triangle condylion-gnathion-gonion) were assessed from lateral cephalograms taken at the start of treatment, on completion of functional appliance therapy and prior to debond. Intra- and inter-observer reliability of CVM staging, cephalometric and statural height measurements were assessed using Cohen’s weighted kappa, intra-class correlation coefficient, and Bland and Altman plots respectively. ANOVA was used to test for statistically significant differences between growth velocities at the CVM stages. Results: 108 participants were included for analysis. The peak in statural height growth velocity occurred at CVM stage 3 (p=0.001). The peak in mandibular growth occurred at CVM stage 3, although this was not statistically significant. Conclusions: The findings of this study demonstrate that CVM staging is valid for identifying the pubertal peak in statural height velocity. The peak in mandibular growth velocity occurred at CVM Stage 3, but this was not statistically significant. Ethical approval: Liverpool East Research Ethics

Committee, 30/10/2013; reference number 13/NW/ 0408; protocol number UoL000751. A qualitative study identifying issues affecting adult craniofacial patients. S.M.N. VISRAM1; D. GILL2; J. SHUTE3; S.J. CUNNINGHAM1 1 UCL Eastman Dental Institute 2 Great Ormond Street NHS Foundation Trust and Eastman Dental Hospital, University College London Hospitals Foundation Trust 3 Eastman Dental Hospital, University College London Hospitals Foundation Trust Objective: The main objective of this study was to assess quality of life (QoL) in adult craniofacial patients and to identify and analyse the main issues affecting QoL. Design: This was a qualitative study conducted through one-one in-depth semi-structured interviews. Setting: The Orthodontic Department, University College London Hospitals NHS Trust and UCL, Eastman Dental Institute. Methods: In-depth, semistructured interviews were conducted with ten adult craniofacial patients. The interviews were digitally recorded and then transcribed verbatim and analysed using framework analysis. This allowed the emergence of major themes and subthemes affecting adult craniofacial patients. Results: Analysis of the interviews revealed 8 main themes, these were: physical issues, emotional issues, effects on education, effects of treatment, coping strategies, relationships, information seeking and future concerns and issues. Although great variation existed amongst the individuals a number of concerning subthemes were identified. These included matters relating to teasing and bullying, as well as issues concerning low mood, anxiety, depression and self-harm. Conclusions: A number of disciplines are involved in the care of these patients and healthcare professionals should be aware of the issues affecting them and know where available support may be accessed. Further research is intended to take place in which a quality of life questionnaire

can be developed and validated before distribution to a wider cohort. Prognostic factors affecting spontaneous space closure following los of the first molar. S.M. PATEL*, J.H. NOAR AND P.F. ASHLEY (Eastman Dental Institute, University College London, UK). Objectives: 1.To determine factors that may predict space closure of the second molar after extraction of the first permanent molar (FPM). 2. Development of a toolkit to aid clinical decision-making. Design and Setting: 148 upper and 153 lower FPM extractions from 81 participants were assessed retrospectively from patients who attended the Eastman Dental Hospital Paediatric Department. Dental age, second molar developmental stage molar, second premolar and second molar angulation and the presence/absence of the third molar were assessed on pre-extraction orthopantomograms. Outcome was assessed via visual examination, study models or radiographs. Analysis involved multilevel, multivariable logistic regression analysis. Results: Closure occurred in 89.9% of upper and 49.0% of lower quadrants. Dental age was statistically, but not clinically, significant within the upper arch (p
