osteosarcoma (os) is a malignant mesenchymal tumor, which rarely occurs in the maxilla. although variable histologic and radiographic features of os have been reported previously, in the majority of the cases painful swelling of the jaw is mentioned as the first clinical presentation. furthermore, early diagnosis and wide surgical resection of the tumor are the most important determinant factor...

anthropometry, a useful method for evaluating craniofacial soft tissues, makes the quantitative description of the face possible. it also assesses the degree of disharmony and imbalance in the growth and development of the face. the aim of this study was to examine the overall common age-related changes of nasomaxillary complex of adolescent boys in northeast iran. three- hundred- twelve 12 to ...

mesenchymal chondrosarcoma (mc) is an uncommon tumor with an aggressive behaviour. we present two cases of mc. the first one is a unique case of mc of the maxilla metastasized from the clavicle. the second describes mc in the mandible with extensive involvement of the condyle. a 31-year-old male and a 22-year-old male presented to saveetha dental college, with a 2-month history of progressive m...

the anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. with the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. immediate implant placement has numerous advantages compared to the delayed procedure including superi...

Osteosarcoma is the most common primary malignancy of bone although only 6% to 10% of osteosarcomas occur in the craniofacial region.1 Within the craniofacial region the mandible is usually reported as the most common site of the involvement, followed by the maxilla and skull.1,2 The average age at the onset of osteosarcoma of the maxillofacial region is about one or two decades later than that...

introduction: many patients suffer from mild, moderate or severe pain during or after root canal therapy. theoretically, post-operative pain control can be achieved by using long-acting local anesthetics. the aim of this study was to evaluate the efficacy of a long acting anesthesia, bupivacaine, on preventing post-operative pain associated with endodontic treatment, and to compare it with lido...

objectives: implant primary stability is one of the important factors in achieving implant success. the osteotome technique may improve primary stability in patients with poor bone quality. the aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. materials and methods: in this controlled randomi...
