Purpose: The purpose of this study was to investigate the effects of specialized Kyokushin Karate exercises on the activity of leg muscles and the height of the medial longitudinal arch in adolescent girls with foot pronation.    Methods: This study recruited twenty-four adolescent girls with foot pronation who voluntarily agreed to participate and were randomly assigned to either a train...

BACKGROUND Recurrent cephalic arch stenosis (CAS) has been linked to high flow and has a high rate of recurrence following angioplasty. This study investigates the effectiveness of access flow reduction in decreasing rapidly recurrent symptomatic CAS. METHODS A retrospective study of patient records from February 2005 to April 2009 was conducted. Patients with brachiocephalic fistulas who had...

AIM The purpose of this investigation was to examine the extent to which arch dimension or tooth size contributes to dental crowding. METHODS AND MATERIALS Two groups of dental casts were selected. Each group consisted of 30 pairs of dental casts including equal male and female samples. The first group had Class I malocclusions without crowding or spacing. The second group exhibited Class I m...

The aim of this study was to evaluate the characteristics (shape of dental arches, overjet and overbite) of the primary dentition of 6- to 39-month-old children from four nurseries of Rio de Janeiro, Brazil, and to associate them to gender and dentition phase. It was observed that 68.6% of the children presented round upper arch, while 31.4% had triangular upper arch; 92% of the children presen...

BACKGROUND Studies of aortic arch plaques with transesophageal echocardiography have demonstrated that complex aortic arch plaques (CAPs) greater than or equal to 4 mm in thickness are associated with ischemic stroke. Recent studies have demonstrated that the morphological features of plaques may aid in the identification of aortic plaques that are more likely to be associated with embolic stro...

It has been proposed that a mass transfer phenomenon called concentration polarization of low-density lipoproteins (LDLs) may occur in the arterial system and is likely involved in the localization of atherogenesis. To test the hypothesis that concentration polarization of LDL may be suppressed by the helical flow pattern in the human aorta, hence sparing the ascending aorta from atherosclerosi...

AIM This research was conducted to study the effect of school-based caries prevention program on the crowding in the early permanent dentition. STUDY DESIGN upper and lower arch crowding was compared between 78 subjects who had received a successful caries prevention programme and 94 control subjects. MATERIALS AND METHODS A study model was taken for each of the subjects. From these models ...

OBJECTIVE The purpose of this study was to investigate the relationship between the mandibular dental and basal arch forms in subjects with normal occlusion and compare them with those of Class III malocclusion using cone-beam computed tomography (CBCT). METHODS CBCT images of 32 normal occlusion (19 males, 13 females; 24.3 years) and 33 Class III malocclusion subjects (20 males, 13 females, ...

AIMS To evaluate the accuracy of dies made from dual arch impressions using different sectional dual arch trays, combinations of elastomeric impression materials, and the sequence of pour of dies. SUBJECTS AND METHODS The dual arch impression materials were grouped into three groups depending on the combination of impression materials used and each group is subdivided into four subgroups. A s...
