Intensively feeding animals can be a costly exercise, and as a result many producers are exploring innovative ways to reduce their input costs. Commercial by-products from the human food industry (eg brewers grain, citrus pulp and apple pulp) have recently become popular in animal production. Bakery waste displays favourable characteristics for animal production, however, limited information is...

OBJECTIVE The present study aimed at analyzing, with the use of dental casts, the transverse changes of the upper and lower dental arches, after non-extraction orthodontic treatment, with self-ligating brackets. METHODS The sample comprised 29 patients, all presenting Class I malocclusion with upper and lower crowding of at least 4 mm and treated only with a fixed appliance, without stripping...

The study of subterranean ant nests has been impeded by the difficulty of rendering their structures in visible form. Here, several different casting materials are shown to make perfect casts of the underground nests of ants. Each material (dental plaster, paraffin wax, aluminum, zinc) has advantages and limitations, which are discussed. Some of the materials allow the recovery of the ants ento...

Dental plaster is one of these products that mainly used to produce dental casts and mounting purposes. Although the cost very low, their inferior compressive strength, low abrasion resistance dimensional instability restricted usage as primary working casts. The inclusion different fillers in gypsum could play an important role improving performance. Aim: aim this study was evaluate physical p...

Originally identified as an ornithischian dinosaur, Crosbysaurus harrisae has been found in New Mexico, Arizona, and its type locality in Texas, as well as in North Carolina. The genus has been reassessed by other workers in light of reinterpretations about the postcrania of another putative Triassic ornithischian, Revueltosaurus. The understanding of Triassic dental faunas has become more comp...

in this paper we propose novel algorithms for retrieving dental images from databases by their contents. based on special information of dental images, for better content based dental image retrieval and representation, the image attributes are used. we propose disr (dental image segmentation and retrieval), a content-based image retrieval method which is robust to translation and scaling of th...

the present report aimed to study an uncommon case of a pair of twins that presented a discordant dental phenotype. family investigation, clinical, radiographic examination and molecular analysis were performed in both girls. molecular analysis confirmed the monozygosity by deoxyribonucleic acid chip technology. one twin presented tooth agenesis in left upper lateral incisor and peg-shaped on t...

The aim of this study was to measure and compare the dimensions of the dental arches on three-dimensional digital study models in children with and without cleft lip and palate before the primary surgery. The sample consisted of 223 digital models of children aged 3-9 months, divided into 5 groups: without craniofacial deformities, unilateral and bilateral incomplete cleft lip and alveolus, uni...

This in vitro study evaluated (1) the dissolution of bovine pulp tissue in solutions consisting of varying NaOCl concentrations and combined with EDTA; and (2) the pH of these solutions before and after the experiment. The independent variables were the concentration and the volume of the solution. Thirty bovine pulps were divided in equal fragments, resulting in 90 fragments of pulp tissue. Ea...
