Findings and conclusions: In immunohistochemical analysis, there were more factors associated with neurological recovery in Stro-1, CD146, ES cell groups compared to PBS and pulp cell grouops. In walking footprint analysis Stro-1, CD146, ES cell group show better recovery but but no significant difference was noted.

The effectiveness of the surgical approach and drug-holiday on the treatment of bisphosphonate related osteonecrosis of the jaw patient
Background: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is an area of uncovered bone in the maxillo-facial region that did not heal within 8 weeks after identification by health care provider, in a patient who was receiving or had been exposed to Bisphosphonate Therapy (BPT) without previous radiation therapy to the craniofacial region. Objectives: The purpose of this study is to compare the surgical treatment with conservative treatment and to evaluate the effectiveness of drug holiday in bisphosphonate related osteonecrosis of the jaw (BRONJ) patients who were diagnosed as stage 2. Methods: From January 2012 to October 2014, seventy two patients who visit to Pusan National University of Dental Hospital were diagnosed as stage 2 of BRONJ. All the patients had taken computed tomography (CT) and panoramic radiography. The surgical treatment including sequestrectomy of necrotic bone and curettage of soft tissue around the sequestrum were performed to fifty patients. Twenty two patients underwent conservative treatment such as antibiotics medications, mouth rinsing and follow up checking for every two weeks. Conclusions: Statistically, the prognosis of patients with stage 2 BRONJ treated with surgery was significantly better than conservative treatment. There was no statistical difference for the preoperative drug holiday.

Department of Oral and Maxillofacial Surgery – Paulista University Assistant Professor, São Paulo, Brazil 2 Department of Oral and Maxillofacial Surgery – Paulista University Chief Professor, São Paulo, Brazil Synovial chondromatosis of the temporomandibular joint is a rare disease characterized by the presence of calcified loose bodies within the joint, first described by Axhausen in 1933.1–4 It is cartilaginous metaplasia that results in the proliferation of abnormal synovial membranes of joints. Cartilaginous nodules form and may become pedunculated and detached from the synovial membrane, so becoming loose bodies within the joint space. We present a case that affected the temporomandibular joint and was treated with arthroscopy, which is an efficient and conservative treatment (Pictures 1–4).

Jung, H.K. Oh Dept. of Oral & Maxillofacial Surgery, School of dentistry, Chonnam National University, Gwangju, Republic of Korea Background: The peripheral nerves can be recovered from injury through regeneration of axons. In order to enhance this recovery, various experimental approaches were reported, such as, the application of an electric field and supplementation with stem cells and neurotrophic factors. Transplantation of human bone marrow stromal cells or skin-derived fibroblasts led to substantially impaired recovery. And also, most adult stem cells have limitations such as the insufficient number of cells and the invasive procedure to obtain them, which limits the clinical application. Objectives: This study was performed to investigate the in vivo therapeutic efficacy of human dental pulpal stem cells in nerve injury model. Methods: To investigate the in vivo therapeutic efficacy of human dental pulpal stem cells in nerve injury model, we transected the sciatic nerve in 300g weight-rat models. Within half hour of removal of the sciatic nerve, Stro-1, CD146, ES cell, PBS, pulp cell were implanted into an artificial nerve conduit for stable supply of cells with best engraftment efficiency and this was connected to the injured nerve. Functional recovery in the improved engraftment efficiency and greater regeneration of injured peripheral nerve was examined at the 1, 3, 5 days after experiment using walking-foot-print analysis and immunehisto-chemical analysis.

with respect to lifestyle and health of the caregiver, which could potentially impact or affect the care they offer their own patients. Method: We will send out an anonymous voluntary web-based questionnaire to all members of ANZAOMS. As the second endpoint we aim to identify risk factors amongst the different groups of surgeons with regards to sleep patterns, obesity, personal difficulties, work related pressures, sedentary lifestyle, and poor diet. Ethics approved by Austin Health Human Research Ethics Committee (LNR/13/Austin/109). Conclusion: We hope to present the results with an indication of any potential variations in health behaviour amongst the groups. It has been shown that individuals identifying high incidences of known risk factors amongst themselves can have a positive impact. We hope that this study may help the individuals concerned address these at an earlier stage in their practicing life.

Background: It has been well documented and researched that poor health and lifestyle can have a negative impact with respect to chronic illnesses increasing morbidity and the risk of burnout.1 The Royal College of Physicians recommended that employers should intervene with the ever-growing scrutiny of patient and health practitioners safety.2 Aims and objectives: Our primary endpoint will be to identify if there is a higher incidence of burnout or stress in a particular area of practice or group of practitioners, by using a questionnaire using the Copenhagen Burnout Inventory (CBI). Also we will look at different groups to identify any pattern of poor behaviour
M. Patil Sparsh Hospital, Bangalore, India Objectives: The purpose of this study was to assess the longterm treatment results of closed reduction rigid MMF for 10 days to 2 weeks followed by functional MMF for unilateral condylar fractures Methods: All patients with unilateral condylar fractures undergoing closed reduction at Sparsh Hospital from 2008 to 2014 were included in this study were included in this retrospective study. Of 31 patients who underwent closed reduction 6 patients were lost to follow up 2 patients had died due to trauma related complications. To evaluate the results of this protocol, 23 patients who reported were examined for gender, diagnosis, age at injury, time since operation, and cause of the fracture. Each group was assessed for maximum interincisal opening, right lateral excursion and left lateral excursion, protrusion of the mandible deviation on opening, occlusion assessed by clinician and patient perception, perception of pain using VAS and subjective assessment of ease in mastication and return to normal pre trauma diet. Findings: 4 patients out of 23 had deviation of the jaw on opening. Two patients had slight pain on chewing hard food (VAS score – 2). 1 patient had mouth opening < 3.5 mm. No patients had significant occlusal disturbances. Conclusions: Closed reduction with rigid MMF for 10 days to 2 weeks followed by functional MMF is a good alternative for patients with unilateral condylar fractures. http://dx.doi.org/10.1016/j.ijom.2015.08.283
