Comparison of tooth derived hydroxyapatite with commercially pure hydroxyapatite
365 significant correlation between video usefulness and viewing rate, viewer’s interaction and video length. The quality of the videos uploaded by the general public was comparatively inferior to those uploaded by the healthcare units. Conclusion: YouTube videos concerning third molars currently available are lack of accurate information and cannot be deemed as a source for general public to raise awareness on mandibular third molars issues. http://dx.doi.org/10.1016/j.ijom.2017.02.1227 Comparison of tooth derived hydroxyapatite with commercially pure hydroxyapatite E.D.S. Azariah ∗ , A. Evangeline, R. Chinnasami Department of Oral and Maxillofacial Surgery, Sri Ramachandra University, Chennai, India Background: There has been a constant search for an ideal bone graft in dentoalveolar surgery. Tooth derived hydroxyapatite has been proposed as a Autogenous tooth derived bone graft material (Auto BT) was proven to show the osteoinductive, osteoconductive and osteogenesis properties.1,2 Objective: To assess the efficiency of tooth derived hydroxyapatite (Auto BT) as a bone graft material by comparing it with commercially available hydroxyapatite (SYBOGRAFT). Methods: The study was designed as a randomised controlled trial with 30 patients. The patients who had a distoangularly impacted third molar were included in the study. Case group were grafted with the tooth derived hydroxyapatite and a control group had SYBOGRAFT placed in their socket. Radiographs were done following extraction and following grafting. After a week the wound healing was evaluated and six weeks later the quality of bone was assessed using a computed tomography scan. Findings: There was no significant different in the postoperative complication and healing of the wound. The mean radiodensity of Auto BT was 943.34 HU with a standard deviation of 157.82 HU and the mean radio density of the control group was 973.94 HU with a standard deviation of 153.18 HU. Conclusion: Though there is no statistical significance between SYBOGRAFT and tooth derived hydroxyapatite. But the organic substances like the bone morphogenetic protein (BMP) and proteins with osteoinductive capacity as well as type I collagen that is similar to alveolar bone is present in tooth derived HA.2 Therefore, it may have the same bone remodelling capacity as autogenous bone.

Educational philosophies within medical graduates undertaking a dental degree when compared with other non-medical graduates M. Bajalan ∗ , Z. Ahmad, S. Roberts Kings College, School of Dentistry, London, United Kingdom Background: Kings College offers the only three-year dental programme for medical graduates within Europe. Dual qualification in medicine and dentistry is a requirement for training in maxillofacial surgery. On the tenth year running, we conducted a study looking at the differences in various parameters relating to educational philosophy. Objective: The aims of this study were to identify the variance in the ways specific student groups approached their undergraduate training. The areas included: learning methodology, attendance, self-directed techniques, career motivation, stress levels and coping strategies, time management and time spent in paid employment. Methods: Questionnaires were used to evaluate how medical graduates on the three-year dental programme compared with university graduates on the four-year programme and school leavers on the five-year programme. Findings: Medical graduates came across as highly motivated self-directed learners with excellent time management skills. Attendance at lectures was poor owing to time spent in paid employment and the basis of previous studies. School leavers on the five-year programme demonstrated grossly contrasting study methodology where the majority attended lectures regularly. Their stress levels were higher when compared to medical graduates despite spending a longer duration on the programme. Graduates on the four-year programme demonstrated a mixture of attributes. Conclusion: Students on different dental programmes within Kings College exhibit an array of different study techniques. Career motivation, past learning experiences, extracurricular commitments and differences in stress coping mechanisms were all thought to be key factors in explaining these differences. http://dx.doi.org/10.1016/j.ijom.2017.02.1229 Analysis masticatory function of influence in complications of patients submitted to bariatric surgery G. Campos ∗ , J. Laureano Filho, J. Campos University of Pernambuco, Brazil Objective: The aim of this study was to analyse the influence of masticatory performance in patients undergoing gastric bypass Roux-Y with and without the use of the ring and to identify factors correlating with postoperative complications. Methods: This was a retrospective and cross-sectional analytical, independent samples. We evaluated 50 patients after bariatric surgery were divided into two groups, 25 patients with the placement of the ring and 25 patients without placing the ring and analysed in the period October 2011 to November 2012. The masticatory performance was evaluated by the colorimetric method, where the colour intensity of the solution of beads stained by fuccina was measured by a spectrophotometer. Results: The used analysis of variance and Pearson correlation coefficient (r) to perform the statistical analysis (P < 0.05). It was found that patients with the presence of the ring in their DGYR and
