Pycnodysostosis: a case report, a brief review of the literature and our treatment strategy
Free Papers—Oral Presentations the coronal aspect of the implant collar using William’s periodontal probe. Each implant bony defect augmented by different forms of polylactic and polyglycolic acids (PLA-PGA). Results: All implants were successfully osseointegrated yielding a survival rate of 100%. Measurement of VDH was applied to all sides, with observation of significant decrease in defect height. The main initial defect height was 5.7 mm (standard deviation = 3), after healing the remaining defect height was reduced to 1.1 mm (standard deviation = 2.1). Conclusion: This study demonstrates that PLA-PGA fisiograft can work as an effective augmentation material in the treatment of implants fenestration and dehiscence doi:10.1016/j.ijom.2009.03.350
O9.70 The investigation of low level laser therapy efficacy on temporomandibular joint disorders with magnetic resonance imaging ˙ Görür ∗ , K. Orhan, A. Öztürk, D.I. S. S¸ahin Department of Oral and Maxillofacial Surgery, Ankara University, Ankara, Turkey
Background and Objectives: Temporomandibular disorders (TMD) are conditions that affect the form and/or function of the temporomandibular joint (TMJ), masticatory muscles, and dental apparatus. Often TMD is associated with pain localised in the TMJ and/or in the muscles of the face and neck. The aim of this study is to evaluate the effectiveness of low-level laser therapy (LLLT) both subjectively and objectively with magnetic resonance imaging (MRI) according to pain, mouth opening, subgroups of TMD, and duration of disorders. Methods: This clinical trial was performed in 12 patients, diagnosed with TMD of multiple causes. All patients received both methods of treatment in two consecutive weeks. LLLT was delivered with a custom made TMJ laser apparatus with a 650-nm wavelength and 15 mW output diode laser, and 904 nm infrared laser with 30 mW output. The amplitude of mouth opening was recorded before treatment and immediately after the therapy by using a millimeter rule. Changes in pain were evaluated by self-administered questionnaire with a visual analogue scale. The MR imaging were performed for objective assessment both pre and post laser therapy.
The effusions, signal intensity ratios of TMJ structures were measured. Results: After LLLT, there was a significant increase in the mouth opening, decrease in pain over time. The MR images showed a decrease in effusions in TMJ joint compartments and the SIR of the disk and TMJ condyle were decreased. Conclusion: LLLT can be considered as a useful method for the treatment of TMDrelated pain, and effective to improve mouth opening. The objective evaluation shows that the effusion diminishes from the joint compartment over time with LLLT. doi:10.1016/j.ijom.2009.03.351
O9.71 Pycnodysostosis: a case report, a brief review of the literature and our treatment strategy C. Voisin ∗ , F. Bianchi, A. Balon-Perin, R. Glineur Department of Oral and Maxillofacial Surgery, Erasme University Hospital, Avenue Nellie Melba, Anderlecht, Belgium
Pycnodysostosis is a rare human autosomal genetic disorder. It is mainly characterised by osteosclerosis of the skeleton, severe bone fragility and short stature. This syndrome usually presents very typical craniofacial deformities such as brachycephaly, hypoplastic midface, micrognathia, open mouth posture, anterior crossbite and dental crowding. We present a report of case of pycnodysostosis of a seven year old boy, admitted in our department. Some of the specific craniofacial and radiological findings that are frequent with pycnodysostosis are reported along with a brief report of the literature, followed by a discussion about a treatment strategy in this case. doi:10.1016/j.ijom.2009.03.352
O9.72 Experience in 15 patients with osteochemonecrosis J. Garcia Linares ∗ , J. González-Lagunas, J. Rubio Palau, J. Mareque Bueno, J.A. Hueto Madrid, G. Raspall Martín Department of Oral and Maxillofacial Surgery, Hospital Quiron, Hospital Vall d’Hebron, Sant Just Desvern, Barcelona, Spain
Background and Objectives: We present our experience with the follow-up of 15 patients with osteochemonecrosis in maxilla or mandible. They had been treated
495
with bisphosphonates, and complications resulted in almost all of them after a dental procedure. Methods: All the patients were treated at our centre, depending on the exploration, extension, pain, radiographic tests and clinical manifestations like swelling of soft tissues, and depending on these criteria we provided a conservative treatment with oral rinses or surgical bone curettage with culture, antibiogram and pathology. Results: Following treatment, all patients are without pain although almost all of them are with bone exposure. Most of the patients had taken zoledronate (11/15) and these patients are the ones with worst evolution of the disease. Location of the disease was 11 in mandible and 5 in maxilla (1 both in mandiblemaxilla). 85% of patients had undergone an exodontia procedure before developing osteochemonecrosis. We performed curettage in 53% of the patients with good evolution in all of them. Conclusions: Osteochemonecrosis is an idiosyncratic disease that a patient suffers with another disease (bone metastasis of breast cancer in most of patients) and zoledronate is the bisphosphonate with worst evolution, and patients with pain, infection or bone sequestrations improve so much with bone curettage and antibiotics. doi:10.1016/j.ijom.2009.03.353
O9.73 Clinical implications of continued alcohol and tobacco consumption after treatment for oropharyngeal malignancies J. Rajinikanth ∗ , M.E. Thomas Department of Maxillofacial/Head and Neck Surgery, Royal Darwin Hospital, Darwin, Northern Territory, Australia
Background and Objectives: Despite the clear association of alcohol and tobacco in the aetiology of oral cancers, continuing abuse of these risk factors in patients who have undergone treatment for these cancers is of concern. To better understand this issue, our study was designed with two specific aims: 1) to examine the prevalence and patterns of continued tobacco/alcohol use after initial treatment, and 2) its association with quality of life. Methods: All patients managed for newly diagnosed mucosal squamous cell carcinomas of the head and neck region at the Royal Darwin Hospital, Australia from 2005–2008 were included. Questionnaires on smoking, drinking, depression and on quality of life were employed. The relation
