background and aims. panoramic radiography is a method widely used because of low absorbed dose in patients (approximately 10 times less than that in the full mouth survey), reasonable cost and time. disadvantages of this radiography technique are magnification and distortion as a result of unequal magnification, which can influence dimensional and angular measurements used in clinical dentistr...

OBJECTIVE Previous studies revealed that hypertrophic cardiomyopathy (HCM) patients have impaired aortic elastic properties with contrasting data about aortic dimensions. We aimed to extend our knowledge about this topic, considering tissue Doppler imaging (TDI) and tissue strain. PATIENTS AND METHODS 25 HCM patients and 25 healthy volunteers matched for age and sex were enrolled. They underw...

Orthodontic treatment for malocclusion correction may involve extraction or non-extraction of specified teeth for esthetic and functional harmony. Antero-posterior and transverse arch dimensional changes following orthodontic treatment has been evaluated using many methods. The present study evaluated the arch dimensional changes after orthodontic treatment in extraction and non-extraction case...

OBJECTIVE This study aimed to assess three-dimensional changes in the temporomandibular joint positions and mandibular dimensions after correction of dental factors restricting mandibular growth in patients with Class II division 1 or division 2 malocclusion in the pubertal growth period. METHODS This prospective clinical study included 14 patients each with Class II division 1 (group I) and ...

The development of the dental arches in children with oral clefts differs from that in a normal population, due to the type and extension of the cleft, surgical procedure and timing, and decreased growth potential. The size of the maxillary and mandibular dental arches and the amount of interdental space in 3-year-old, cleft-affected and non-cleft children was investigated. Fifty non-cleft (NON...

the osteology of the hyoid and branchial arches in several representatives of eurypterygian fishes were examined. the hyoid arches consist of a single basihyal and urohyal, and the arch on each side consists of a dorsal and a ventral hypohyal, an anterior and posterior ceratohyal, an interhyal, and branchiostegal rays that are borne on the ceratohyals. the branchial arches consist of three sing...

OBJECTIVES The study determined, in a population-based setting, whether dilatation of the thoracic aorta is an atherosclerosis-related process. BACKGROUND The role of atherosclerosis in thoracic aortic dilatation and aneurysm formation is poorly defined. METHODS The dimensions of the thoracic aorta were measured with transesophageal echocardiography in 373 subjects participating in a population...
