Outcome of Different Treatment Modalities of Fracture Zygoma.

Objectives: This study aimed to determine the pattern of fractured zygoma, different treatment modalities, and complications of the treatment in our center. It also aimed to determine the association between the treatment modalities and complication of treatment, and association between number of fixation and complication.

Methodology: A retrospective review was conducted from January 2008 until December 2011.

An intraorbital metallic foreign body.

A 30-year-old male presented with diplopia for 20 days post occupational accident involving left side of his nose, while he was working with a nail gun. He was fully conscious and did not have any neurological deficits. Patient narrated the mechanism of injury and was sure that the nail fell down after hitting the left side of his nose.

3D mapping of safe and danger zones in the maxilla and mandible for the placement of intermaxillary fixation screws.

Intermaxillary (IMF) screws feature several advantages over other devices used for intermaxillary fixation, but using cone beam computed tomography (CBCT) scans to determine the safe and danger zones to place these devices for all patients can be expensive. This study aimed to determine the optimal interradicular and buccopalatal/buccolingual spaces for IMF screw placement in the maxilla and mandible. The CBCT volumetric data of 193 patients was used to generate transaxial slices between the second molar on the right to the second molar on the left in both arches.

Arteriovenous malformation of the mandible: a rare but life-threatening disease.

AVM in the mandible is rare. It may present with recurrent episodes of unexplained gingival haemorrhage, bony swelling, tooth mobility or facial asymmetry. We reported our experience in managing a case of a 15 year old Malay girl who presented with a life threatening bleeding from her mandible.

Comparative study between dense and porous hydroxyapatite using light and scanning electron microscopy.

This in vivo study revealed that porous hydroxyapatite (PHA) and dense hydroxyapatite (DHA) are good implant materials that can accelerate bone healing and resorbed in acceptable time. But there were differences in the mechanism of the resorption of DHA and PHA due to variability in the physical properties and osteogenicity.
