Osteosarcoma of the posterior maxilla.

Osteosarcoma is a very uncommon tumor of the maxillofacial region. Due to the occurrence of the tumor at a young age and its aggressive nature, radical surgery forms the only modality of treatment. A combination of radiotherapy and postoperative chemotherapy has been used for the management of this tumor. A case report of osteosarcoma of the posterior maxilla in an adolescent with a 1-year disease-free follow-up is presented in this report.

CBCT Cyst Leasions Diagnosis Imaging Mandible Maxilla.

The bony anatomy and the soft tissue contours of the maxillofacial region, along with the oro dental tissues, is very complex. In earlier times, analog radiographs of the skull, the mandible and the sinuses, along with intraoral films, were the only tools which were available for dentists. The past decade has seen a revolution in dental imaging, with the introduction of Cone beam computed tomography/cone beam volumetric tomography (CBCT/CBVT). In this article, we have discussed the value of CBCT in diagnosis and treatment planning which we observed in four cases of maxillofacial cystic lesions. It proved to be a multifaceted win-win situation for the diagnostician, the patient and the operating surgeon. The 3D imaging led to a precise pre-operative surgical planning, resulting in a surgery that was minimally invasive, minimally morbid and time saving and at the same time, conservative, yet complete.

Utilization of mobile dental vans at post graduate dental institutions in India.

BACKGROUND: Mobile Dental Van (MDV) removes the barrier of accessibility and improves the care of underserved populations. Dental institutions across India, providing postgraduate training in dental public health organize and conduct MDV programs as part of their curriculum. AIM: To describe the structure, conduct and utilization of MDV programs in consideration to duration of use by the academic institutions for oral health care delivery in rural areas. METHODS: Hundred postgraduates in Public Health Dentistry representing 27 dental institutions of India completed a 40 item questionnaire on MDV program and utilization. Descriptive statistics and Fisher's exact test were used for statistical analysis. RESULTS: The mobile dental van programs were more curative with limited orientation towards preventive services. The institutionally sponsored programs with experience of more than 10 years had better organized setup and adequate emergency management system together with electricity, water and storage facilities. Chair side assistants were employed in 90 percent of newer programs compared to only 50 percent of older programs. Dental hygienists were helping the dentists in only 60 percent of programs. CONCLUSIONS: The utilization of MDV in treating rural underserved is indispensable, but revenue and high productivity is difficult to achieve as lower socioeconomic patients are predominantly served. MDV programs operational in postgraduate institutions have to improvise on correcting the shortcomings regarding the facilities and manpower to improve the utilization of the programs.
