OBJECTIVE To determine the distribution of skeletal and dental malocclusions in a sample of Saudi orthodontic patients. METHODS Six hundred and two randomly selected pretreatment orthodontic records were evaluated in this descriptive, retrospective study conducted between June to September 2009 at the Orthodontic Clinic of the College of Dentistry, King Saud University, Riyadh, Kingdom of Sa...

Night shifts work in particular is the most frequent reasons for circadian rhythm disruption and subsequent psychological physiological disturbances, especially increased risk of cardiovascular respiratory ailments compared to daytime workers. Alternate nostril breathing about 15 minutes was known have effect over cardiac, parameters muscle strength. Hence aim interest assess effects alternate ...

Simultaneous bioelectricity generation and dye degradation was achieved in the present study by using a combined anaerobic-aerobic process. The anaerobic system was a typical single chambered microbial fuel cell (SMFC) which utilizes acid navy blue r (ANB) dye along with glucose as growth substrate to generate electricity. Four different concentrations of ANB (50, 100, 200 and 400 ppm) were tes...

INTRODUCTION In growing patients with skeletal discrepancies, early diagnosis, evidence-based explanations of etiology, and assessment of functional factors can be vital for the restoration of normal craniofacial growth and the stability of the treatment results. The aims of our study were to compare the 3-dimensional pharyngeal airway volumes in healthy children with a retrognathic mandible an...

INTRODUCTION The purpose of this study was to determine the relationship between the length of the lingual frenulum and craniofacial morphology and test the hypothesis that skeletal Class III malocclusion is related to tongue-tie, in which the lingual frenulum is short and restricts the mobility of the tongue. METHODS The sample consisted of 50 skeletal Class I patients (0° < ANB angle < 4°),...

Objective To assess the ANB angle's and Wits appraisal's diagnostic performance using an extended version of Receiver Operating Curve (ROC) analysis, which renders ROC surfaces. These were calculated for both the conventional and normalized cephalometric tests (calculated by exchanging the patient's reference landmarks with those of the Procrustes superimposed sample mean shape).The required 'g...

Accessory Navicular Bone (ANB) (os navicularum or os tibiale externum) is a common variant of secondary ossification present in 5 to 10 % the population. Due its unique anatomical location foot and associated relation with tibialis posterior tendon, these are usually symptomatic type 2 ANB 3 stages. Often patients can develop plantar fascitis bunions calcaneal spur.Case Report: A 20 year old fe...
