Evaluation of bone regenerative capacity in rats claverial bone defect using platelet rich fibrin with and without beta tri calcium phosphate bone graft material.

Aim: To compare bone regeneration in noncritical rat calvarial bone defects filled with platelet-rich fibrin (PRF), alone or combined with beta-tricalcium phosphate (β-TCP), using micro-computed tomographic (MCT) evaluation.

Animals And Methods: Two calvarial bone defects were created in each of 45 male Sprague-Dawley rats (age: 20-22 weeks, weight: 350-450 g), using a dental trephine with an external diameter of 3 mm. The 90 defects were randomly allocated among three groups, each containing 30 unilateral defects in a total of 30 rats.

Changes in quality of life after orthognathic surgery in Saudi patients.

Aim: This study was conducted to measure the impact of orthognathic surgery on quality of life in Saudi patients.

Materials And Methods: Patients with a discrepancy of 5 mm or more who underwent orthognathic surgery either single jaw or bimaxillary at the Department of Oral and Maxillofacial Surgery, College of Dentistry, King Saud University, between September 2007 and June 2013 were included in the study. They were asked to complete the Arabic version of the 22-item Orthognathic Quality of Life Questionnaire (OQLQ) preoperatively and postoperatively.

Dental extraction in patients on warfarin treatment.

Background: Warfarin is one of the most common oral anticoagulants used to prevent thromboembolic episodes. The benefits of discontinuation of this drug before simple surgical procedures are not clear and this approach could be associated with complications. The aim of this study was to evaluate the risk of bleeding in a series of 35 patients (in cases where the international normalized ratio [INR] is less than 4) following simple tooth extraction without modification of the warfarin dose given to patients.

The effects of surgicel and bone wax hemostatic agents on bone healing: An experimental study.

Background: The biological effects of hemostatic agends on the physiological healing process need to be tested. The aim of this study was to assess the effects of oxidized cellulose (surgicel) and bone wax on bone healing in goats' feet.

Materials And Methods: Three congruent circular bone defects were created on the lateral aspects of the right and left metacarpal bones of ten goats.

Modifying gummy smile: a minimally invasive approach.

Aim: Excessive gingival display is a problem that can be managed by variety of procedures. These procedures include non-surgical and surgical methods. The underlying cause of gummy smile can affect the type of procedure to be selected.

Patterns and etiology of maxillofacial fractures in Riyadh City, Saudi Arabia.

Objective: The aim of the present study was to study the etiologies and patterns of maxillofacial fractures in patients treated in Riyadh City, Saudi Arabia, between 2007 and 2011.

Patients And Methods: Data were obtained through a retrospective review of 237 patients admitted to the King Saud Medical City Dental Department with a diagnosis of maxillofacial trauma. After excluding patient files with incomplete or unclear records, and cases in which computed tomography showed no evidence of fracture, the files of 200 patients with a diagnosis of maxillofacial fracture were included in the study.

Evaluation of bone regenerative capacity following distraction osteogenesis of goat mandibles using two different bone cutting techniques.

Purpose: To compare the regenerative capacity of goat mandibles following sagittal split osteotomy and distraction osteogenesis with a vertical body osteotomy.

Animals And Methods: Bilateral vertical and sagittal body osteotomy was performed on the left and right sides of the mandibles in 18 goats. The distraction period lasted for 10 days at 1 mm/day.

Surgical treatment of keratocystic odontogenic tumour: A review article.

KCOT is one of the most aggressive odontogenic cysts with a high recurrence rate, this was explained histopathologically as it typically shows a thin, friable wall, which is often difficult to enucleate from the bone in one piece, and have small satellite cysts within the fibrous wall. Multiple surgical approaches were introduced including decompression, marsupilization, enucleation with or without adjunct (Carnoy's solution, enucleation) and resection. Depending on other studies KCOT can be conservatively treated with enucleation and application of Carnoy's solution or cryotherapy.

The use of a single titanium microplate in displaced pediatric parasymphysial mandibular fractures.

Objective: The objective of this study was to evaluate the use of one titanium microplate in the fixation of displaced pediatric parasymphysial mandibular fractures.

Materials And Methods: The study was conducted on 7 children in the mixed dentition stage with displaced parasymphysial fracture. Patients' age ranged between 5 years 9 months and 8 years 4 months with an average of 7 years 1 month.
