OBJECTIVE Multiple subsequent procedures directed at the arch and/or the left ventricular outflow tract are frequently required after interrupted aortic arch repair. We the investigated patterns and factors associated with these subsequent procedures and mortality. METHODS We reviewed the data from 447 patients with interrupted aortic arch at 33 institutions enrolled from 1987 to 1997. We cla...
STATEMENT OF THE PROBLEM The stability of orthodontic treatment depends on preserving the patient's pretreatment arch form and arch size during and after treatment. PURPOSE This investigation was aimed to study the size and shape of Iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...
methodology non-native participants in this study were sixty ba students majoring in english literature and teaching english as a foreign language at khayyam university of mashhad. they were senior students, between 21 to 24 years old, who had studied english for at least three and a half years and had passed several courses including grammar, reading, conversation, and writing. this was assum...
The treatment of Class I malocclusion treatment is to arrange the teeth position in a good arch form. Arch form consists of tooth size and arch dimension (intercanine width, canine depth, intermolar width, molar depth). Several ways are developed to describe arch form. A lot of methods used to describe arch form qualitatively. The objective of this study is to develop qualitative arch form diag...
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...
Introduction: A study on the presentation of a modified beta function formula to predict maxillary arch form in patients with cleft palate (CLP) is of great importance. In order to have this information, this study was done to present a modified beta function formula for predicting upper dental arch of patients with cleft lip and palate (CLP) and to assess its accuracy. Since this information c...
Background and Aim: Infection control is an integral part of dentistry and dental impressions are considered an important issue in cross contamination. The aim of this study was to investigate the dimensional stability of two irreversible hydrocolloid materials, Alginoplast and Iralgin after disinfection with 5.2% sodium hypochlorite, used with immersion and spraying methods. Material and Metho...
Computer image monitoring was used for evaluation of dental arch changes. A new special device captured geometrically calibrated images permitting comparison of several different dental casts. In the first part of this study 792 sets of study casts were screened. Measurements of dental arch width between reference points of canines, first premolars and first molars were made: upper jaw: men: ca...
