objective: various techniques of composite placement have been used to decrease microleakage around the composite restorations. due to controversial results, the present study was conducted to investigate the effect of different placement techniques on microleakage in class v composite restorations. materials and methods: sixty class v cavities were prepared on the buccal and lingual surfaces o...

OBJECTIVE To determine whether a swimmer's view or supine (trauma) oblique views are more likely to visualise the lower cervical spine when a lateral view fails to show the cervicothoracic junction. DESIGN A prospective study comparing two 20 week periods. In the first phase the swimmer's view was performed as an additional view when the cervicothoracic junction was not demonstrated. In the s...

[Purpose] The aim of this study was to determine the effect of three different bridge exercises on internal oblique, external oblique, transverse abdominis, and erector spinae activities. [Subjects and Methods] Forty-five subjects with chronic low back pain participated in this study. The training outcome was evaluated with three different testing methods: supine bridge exercise, supine bridge ...

PURPOSE To search for a new definition of muscle hypoplasia in congenital or idiopathic superior oblique muscle palsy. DESIGN Retrospective case-control study. METHODS Cross-sectional areas of the superior oblique and 4 rectus muscles near the eye globe-optic nerve junction were measured by an image analysis software on magnetic resonance images of 50 patients with congenital or idiopathic ...

Brown (I950) defined the features of the superior oblique tendon sheath syndrome and reported five cases. He postulated that the restriction in elevation of the affected eye in the adducted position was caused by a congenitally short anterior tendon sheath of the superior oblique muscle. As the eye moved into adduction, this ligament-like sheath became taut and strongly opposed the action of th...

The contention is examined that the oblique effect, i.e., the well-known performance deficit in detecting orientation difference in oblique lines as compared to vertical and horizontal ones, has its origin in a relative deficiency of neurons with obliquely-oriented receptive fields in the primary visual cortex. Psychophysical observations demonstrate a prominent oblique effect also in visual ta...

The superior oblique tendon sheath syndrome was first described by Brown (I950). The essential feature is a limitation of elevation in adduction caused by a short or inadequately mobile anterior segment of the superior oblique tendon and its sheath. Treatment of the condition is indicated if an abnormal head posture is necessary in order to maintain an adequate field of binocular single vision;...

The psychological oblique effect, a well-known phenomenon that humans and some mammals are more visually sensitive to cardinal (vertical and horizontal) contours than to oblique ones, has commonly been associated with the overrepresentation of cardinal orientations in the visual cortex. In contrast to the oblique effect, however, Essock et al. [E.A. Essock, J.K. DeFord, B.C. Hansen, M.J. Sinai,...
