introduction althoughthere is a consensus that the economic burden of burn injury is high, but few studies have conducted about cost of burns injury among pediatric in developing countries. we explored the main factors influencing on hospital costs and length of stay (los) associated with pediatric burns injury in kermanshah, iran. methods and material we performed a review ofmedical records fr...

Ectodermal organs, such as the tooth, salivary gland, hair, and mammary gland, develop through reciprocal epithelial-mesenchymal interactions. Tooth morphologies are defined by the crown width and tooth length (macro-morphologies), and by the number and locations of the cusp and roots (micro-morphologies). In our current study, we report that the crown width of a bioengineered molar tooth, whic...

A method is presented that allows the accurate measurement of the tooth pair stiVness of a pair of spur gears. The method reveals the stiVness behaviour throughout the full length of the normal path of contact and also into the extended contact region when tooth corner contact occurs. The method makes use of the properties of transmission error plots for mean and alternating components over a r...

the operation was begun that almost every case in British practice entailed the mother's death, and as the child had been previously destroyed, the operation got to be looked upon as almost necessarily fatal both to mother and child. I saw the late Dr. Dyce of Aberdeen perform the operation on a dwarf whose pelvis measured full three inches in the conjugate diameter. The forceps had been tried ...

The aim of this study was to document variation of deciduous tooth formation and eruption. The material comprises 121 individuals of known or estimated age (using tooth length) from Spitalfields in London, and radiographs of 61 healthy living children aged 2-5 years. Other skeletal material from two medieval Scottish archaeological sites (Whithorn, N=74; Newark Bay, N=59) was also examined. Sta...

OBJECTIVE Provide reference basis for the clinical implant restoration to select implant diameter through measuring each data of 7 teeth in the dental neck of bilateral upper and lower jaws of the young volunteers with normal dentition. METHODS Select 30 healthy young volunteers with complete dentition but no malocclusion, take cone beam CT (CBCT), measure the mesiodistal and buccolingual dis...

The aim of this prospective clinical study was to evaluate the short-term and long-term skeletal and dental changes after mandibular osteodistraction with tooth-borne appliances in adult orthodontic patients. The sample consisted of 10 non-growing Caucasian patients with a Class II skeletal relationship due to mandibular deficiency, together with Class II dental malocclusion. All patients under...

An accurate determination of the root canal length, which is the most critical procedure in the endodontic treatment of a tooth, is commonly performed nowadays by electronic apex locators which are based on electrical impedance measurements. In this paper tooth impedances were measured in vitro on extracted tooth in alginate material using HP 4284A LCR meter and a specially designed stalk with ...
