The aims of this investigation were to determine whether stabilization of maximum voluntary bite force (MVBF) occurs between 15 and 18 years of age in subjects with a normal occlusion, and to assess the influence of gender, body mass index (BMI), morphological occlusion, and jaw function measured by the number of occlusal contacts, overjet, overbite, maximal mouth opening, mandibular deflection...

A new method that employs a cerebral perfusion imaging agent, 99mTc-HMPAO, is described for identifying those patients who clinically pass an internal carotid artery balloon test occlusion but who then may develop a cerebral infarction after permanent occlusion. Test balloon occlusion of the internal carotid artery was performed in 17 patients, and 99mTc-HMPAO was injected intravenously while t...

INTRODUCTION Tooth-size studies are important in orthodontics. Our aim in this study was to establish normative data on tooth size with a clustering method. METHODS Dental casts of 307 subjects with normal occlusion were examined. In these subjects, the tooth-size data sets in the maxilla and the mandible were clustered for men and women by using multivariate normal mixture models. This analy...

background. this study aimed to evaluate whether the parents’ knowledge about the adverse effects of oral habits and dentoskeletal discrepancies would improve by an educational pamphlet. methods. a parallel-group randomized clinical trial was conducted on parents in kindergartens of shiraz, iran, 2013. the parents completed a designed questionnaire to determine the pre-intervention score. the s...

We retrospectively studied 46 patients with symptomatic retinal artery occlusion and assessed the pattern and extent of carotid artery disease ipsilateral to the retinal artery occlusion. Ipsilateral internal carotid artery atherosclerotic lesions were virtually limited to the cervical arterial segment; 50% of such lesions were plaques or stenoses of less than or equal to 60%, whereas 15% of th...

Parent artery occlusion is an effective treatment for giant intracranial aneurysms that cannot be clipped directly by surgery in patients who tolerate balloon test occlusion. However, concern remains that impaired hemodynamics after parent artery occlusion may cause delayed ischemic events in the ipsilateral hemisphere. We used computed tomography perfusion studies to evaluate the cerebral hemo...

The aims ofthis study were (1) to apply the quadrilateral analysis to Saudi adult male and female patients with normal occlusion, (2) to compare the results to Saudi adult male and female with anterior openbite, and (3) to evaluate the correlation of the quadrilateral variables. The normal occlusion sample consisted of 60 lateral skull radiographs (30 male and 30 female) of Saudi adults with no...

Basilar artery occlusion is not a diagnosis which is frequently made, although, since the clarification of the clinical manifestations by Kubik and Adams (1946), more cases are being recognized. The following two cases are reported because no instances of basilar artery occlusion in childhood have been found in the literature, and because in one of the patients the occlusion was a completely is...

Esthetic anterior dental appearance depends on the alignment, occlusion, and exposure of anterior teeth.1–3 In order to establish adequate alignment and occlusion, the upper and lower incisors need to be proportional in size. Interarch tooth size discrepancy (ITSD) is defined as a disproportion in the mesiodistal dimensions of teeth of opposing dental arches. In the absence of a proportional ma...

This study was intended to correlate the appearance of the cavernous segment of the carotid artery on MR images with the presence of significant stenosis or occlusion of the cervical carotid artery as seen on angiograms in 37 patients with cerebrovascular disorders who had brain MRI and arteriography. Three patients demonstrated an isointense signal within the carotid artery's cavernous segment...
