A novel supramolecular plaster, (AEDPH(3))·(BtaH) (1), is synthesised and characterized. The supramolecular plaster is easy to synthesise and process, and displays good mechanical properties. It can adsorb and eliminate formaldehyde (HCHO) with high efficiency and exhibits very interesting HCHO/ultraviolet ray-induced luminescence switching.

Background: Distal radius fractures are among the most prevalent fractures predictive of probable occurrence of other osteoporotic fractures. They are treated via a variety of methods, but the best treatment has not been defined yet. Objectives: This study was performed to compare the results of open reduction and internal fixation with locking plates versus the pin and plaster method. Material...

The aim of this study was to determine the reproducibility, reliability and validity of measurements in digital models compared to plaster models. Fifteen pairs of plaster models were obtained from orthodontic patients with permanent dentition before treatment. These were digitized to be evaluated with the program Cécile3 v2.554.2 beta. Two examiners measured three times the mesiodistal width o...

THE JOURNAL OF PROSTHETIC DENTISTRY 113 The most commonly used molds in the subspecialty of facial prosthetics are made of dental plaster and stone. The molds’ material advantages are that they are economical, time efficient, and easy to fabricate. The disadvantages are wear with repeated use for prosthesis fabrication, they must be thoroughly dry before processing with moisture sensitive facia...

The form of primary and permanent teeth can differ morphologically from that which is considered normal, completely or in some parts. The changes in tooth form can be hereditary or caused by some disease or trauma. Fusion is a union of one or more teeth during development. Gemination means that two separate morphological units were created by division of the tooth germ. The intention of this st...

CREDIT is generally given to Taggart1 for introducing the cast gold inlay to the dental profession. Although he realized that gold shrinks when cooled from molten state to solid state of room temperature, the investment available to him did not supply sufficient compensation. In 1910, Van Horn2 published a paper dealing with a method by which he obtained the compensation by means of wax expansi...

conclusions in treatment of intra-articular distal radius fractures in middle-aged patients internal fixation with locking plates may be prefered to pin and plaster as the treatment of choice. results sf-36 test demonstrated a better general health (p < 0.001), mental health (p = 0.006), physical functioning (p < 0.001), social functioning (p < 0.001) and energy/fatigue (p < 0.001) in lcp group...

ment recommended are eminently practical and good. We notice that the author speaks with high approval of Sayre's plaster-of-Paris jackets in spinal caries, and that he prefers the horizontal suspension on a hammock to the vertical method of suspension by the head and arms. We are quite of his opinion, but we do not see why he should always speak of Sayre as " Sayer." In the treatment of parapl...

The present study is concerned with the investigation of mechanical properties of A713 alloy castings produced by investment casting process using expandable polystyrene as the pattern material and the plaster of paris as the mould material. Experiments were conducted as per Taguchi’s L9 orthogonal array. Castings were made under the constraint of different process parameters like mould firing ...

OBJECTIVE To examine the intra- and interexaminer reliability of assessing rotation of teeth on photographed study casts. In addition, the reliability parameters of two examiners scoring in mutual consultation were compared with the reliability parameters by one observer. MATERIALS AND METHODS Standardized photographs of sets of maxillary and mandibular plaster casts of 10 patients before tre...
