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...

BACKGROUND AND AIMS Nowadays centric relation is defined as a musculoskeletal stable position, with the condyles forward, as far upward as possible, centered transversely and with the articular disc properly interposed. On the other hand, centric occlusion or maximum intercuspidation is a dental determined position. The purpose of this pilot study is to evaluate the direction, frequency and mag...

PURPOSE Facial asymmetry often persists even after mandibular deviation corrected by the bilateral sagittal split ramus osteotomy (BSSRO) operation, since the reference facial sagittal plane for the asymmetry analysis is usually set up before the mandibular menton (Me) point correction. Our aim is to develop a predictive and quantitative method to assess the true asymmetry of the mandible after...

This paper reports the treatment and 12-year follow-up of a patient 7 years old who had been diagnosed with Aarskog-Scott syndrome. The patient had a history of premature multiple tooth loss, vertical dimension loss and severe dentoalveolar discrepancy. Orthopedic and orthodontic rehabilitation treatments were performed to improve the patient's esthetic, functional and psychological condition. ...

Abstract. It is shown how an arbitrary set of points in the hypercube can be Latinized, i.e., can be transformed into a point set that has the Latin hypercube property. The effect of Latinization on the star discrepancy and other uniformity measures of a point set is analyzed. For a few selected but representative point sampling methods, evidence is provided to show that Latinization lowers the...

Face representation in the wild is extremely hard due to large scale face variations. Some deep convolutional neural networks (CNNs) have been developed learn discriminative feature by designing properly margin-based losses, which perform well on easy samples but fail samples. Although some methods mainly adjust weights of training stage improve discrimination, they overlook distribution proper...

BACKGROUND Anterior segment imaging using fluorescein angiography is only suitable in lightly pigmented irides as the brown pigmentation of the iris masks fluorescein transmission. Indocyanine green (ICG) angiography has excellent penetration of pigment epithelium and, therefore, has potential application in detecting perfusion changes of dark irides after strabismus surgery. METHODS A prospe...

PURPOSE We investigated whether differences in the pattern visual evoked potentials exist between patients with convergence insufficiency and those with convergence insufficiency and a history of concussion using stimuli designed to differentiate between magnocellular (transient) and parvocellular (sustained) neural pathways. METHODS Sustained stimuli included 2-rev/s, 85% contrast checkerboa...
