The evolution of tribosphenic molars is a key innovation in the history of Mammalia. Tribospheny allows for both shearing and grinding occlusal functions. Marsupials and placentals are advanced tribosphenic mammals (i.e., Theria) that show additional modifications of the tribosphenic dentition inclu …
Conodonts are chordates that resembled eels. The entire class of conodonts was wiped out by the Triassic-Jurassic extinction event, which occurred 200 million years ago.. Researchers used X-rays to create computer models of the eight paired, food-processing structures from fossils of the Wurmiella excavata. The tips of the teeth are just 2 micrometers across. Using finite-element analysis, which uses numerical analysis to approximate the solutions of partial differential equations, the scientists compared conodont teeth with similar-sized bat molars. The findings were published in the journal Proceedings of The Royal Society B.. Conodonts relied on minuscule forces that were concentrated because of the extreme sharpness of their teeth. They didnt use muscular force as mammals do and conodont teeth sliced from left to right, instead of up and down. The sharpness would have made the teeth brittle, but conodonts may have been able to re-sharpen them, a quality that other vertebrates have failed to ...

What is Mixed Dentition? Mixed Dentition is the situation when both deciduous and permanent teeth are present. Save on dental care procedures with a dental plan.
A positive mold for use in creating an orthodontic appliance is produced by obtaining a digital dentition model, such as a 3D geometric surface model or a 3D volumetric image model, that defines the shape of an orthodontic appliance and then altering the digital dentition model to remove a portion that does not affect the shape of the orthodontic appliance. The altered digital dentition model then is used to construct a positive mold for the orthodontic appliance. Processing circuitry, such as a programmed computer, is used to obtain and alter the digital dentition model. A rapid prototyping device, such as a stereolithography machine, is commonly used to construct the positive mold.
The fossil record of conodonts may be among the best of any group of organisms, but it is biased nonetheless. Pre- and syndepositional biases, including predation and scavenging of carcasses, current activity, reworking and bioturbation, cause loss, redistribution and breakage of elements. These biases may be exacerbated by the way in which rocks are collected and treated in the laboratory to extract elements. As is the case for all fossils, intervals for which there is no rock record cause inevitable gaps in the stratigraphic distribution of conodonts, and unpreserved environments lead to further impoverishment of the recorded spatial and temporal distributions of taxa. On the other hand, because they are resistant to abrasion and can withstand considerable metamorphism conodonts can preserve evidence of otherwise lost sequences or environments through reworking.. We have conducted a preliminary investigation into how the various forms of gross collecting bias arising from period to period ...

Trechnotheria is a group of mammals that includes the therians and some fossil mammals from the Mesozoic Era. In the Jurassic through Cretaceous periods, the group was endemic to what would be Asia and Africa. Trechnotheria has been assigned various ranks, but was originally called a "superlegion" by the original author. One reference has defined the Trechnotheria as the clade comprising the last common ancestor of Zhangheotherium and living therian mammals, and all its descendants. Like most Mesozoic mammal groups, early trechnotherians are known mainly from their teeth. Hence, one of the most prominent features of this group is the "hypertrophied postvallum/prevallid shearing mechanism", along with other dental characters. Features of the shoulder blade, tibia, humerus, and ankle joint also diagnose this clade. A cladogram compiled by Mikko Haaramo and based on individual cladograms of after After Luo, Cifelli & Kielan-Jaworowska, 2001, Luo, Kielan-Jaworowska & Cifelli, 2002 and, ...
But maybe the show could have retained some use if all of this human-like/fictional appearance and behavior was there to illustrate some greater true scientific fact, that even network execs think viewers could remember. Alas, no. The implication of the Eoraptor portion was that dinosaur success was due to more complex parental care, but my impression has been that evidence for such care is limited to maniraptorans, supposed evidence for care in hadrosaurs (and thus Ornithischia) has been refuted, and that baby sauropods were too small to associate with adults and arent apparent in herd trackways. And even the mosasaur cares for its babies enough to get revenge on sharks for eating them (vengeance is such a widespread trait in squamates...). As does the Cretaceous mammal, more realistically. If you want to make the point dinosaurs were probably often brightly colored with display structures as the Gigantoraptor portion tries to, a far superior method would be to show say ten different ...
How to Regain Good Dental Formula. There is a significant portion of the country population who have had to persevere dental related appearance challenges. Stained dentals and poor arrangement of teeth are just but some examples of the abnormalities. Failure to understand that the problem can be solved is the primary reason many people have accepted to live with those conditions. Price consideration has also forced a significant number to shy away from visiting dental experts often giving away ones health for money. One should never be deceived to think that saving some dollars can keep one away from dental complications.. Anyone can be a candidate of teeth problems that affect looks or prevent one from having a real smile. An individual who has ever been affected by dental challenges can tell the story. These complications may also affect a close family member or a friend. In this piece of writing, there is a description of various forms of assistance one can obtain from a cosmetic ...
With the exception of the maras, which have a more rabbit-like appearance, caviids have short, heavy bodies and large heads. Most have no visible tails. They range in size from the smaller cavies at 22 cm in body length, and 300 grams in weight, up to the capybara, the largest of all rodents at 106 to 134 cm in length, and body weights of 35 to 66 kilograms. Even larger forms existed in the Pliocene, such as Phugatherium, which was about the size of a tapir.[1] They are herbivores, eating tough grasses or softer leaves, depending on species. The dental formula is similar to that of various other rodents: 1.0.1.31.0.1.3. Females give birth to two or three furred and active young after a gestation period of 50 to 90 days in most species, or 150 days in the capybara. In most species, they are sexually mature within a few months of birth, although in capybaras, maturity is not reached until around 18 months.[2] Social organisation varies widely among the group. Many cavies are promiscuous, forming ...

The morphology of the lower jaw and teeth of the legless lizard Pseudopus apodus (Anguimorpha, Anguidae, Anguinae) from Eurasia are described in detail and compared with those of other species of the subfamily Anguinae. The lower jaw anatomy of Pseudopus, especially the dentary and teeth, clearly differs from the genera Ophisaurus and Anguis. Even so, Ophisaurus is largely uniform in its lower jaw morphology across species. The teeth of North American Ophisaurus are slender cylinders, the shafts are mesiodistally compressed and bulge lingually; the apices are curved lingually and posteriorly and have weakly developed cutting edges. Southeast Asian and North African Ophisaurus present conical teeth, with broadened bases, apices more distinctly curved lingually and posteriorly, and cutting edges that are distinctly developed. The lingual surfaces of the tooth apices are striated in Ophisaurus and Pseudopus. The lower jaw of Ophisaurus is in many respects similar to that in Anguis, however, the ...
Evidence suggests that energy-protein malnutrition is associated with impaired growth and development of facial bones. The objective of this study was to investigate the association between nutritional status and reduced space for dental eruption (crowding) in permanent dentition. A cross-sectional study with probabilistic sampling design was used. We evaluated 2,060 students aged 12 to 15 years enrolled in schools in the northeast of Brazil. Crowding was defined according to World Health Organization (WHO) as misalignment of teeth due to lack of space for them to erupt in the correct position. Nutritional status was evaluated by means of body mass index and height-for-age, using the WHOs reference curves. Parents and adolescents responded to a questionnaire about demographic, socioeconomic, biological and behavioral characteristics. The associations were estimated by odds ratio (OR) in multivariate logistic regression analysis (alpha = 0.05). Confounding and effect-modification were taken into account
Eruption is a complicated process where teeth begin to appear through the gums.Humans have 2 sets of teeth, namely primary dentition and permanent dentition.Primary dentition consists of 20 baby teeth and erupts when infants are around 6 months of age. Permanent dentition consists of 32 teeth which starts erupting at the age of 6 years old ...
The Soom Shale is perhaps most famous for conodonts. The remains of this taxon exemplify the quality of preservation, the unusual composition of the fossils and that Soom taxa are often anatomically peculiar members of their kind. Conodonts are mostly represented in the fossil record by millimetre-sized phosphatic elements recovered after acid preparation of rocks from Cambrian to Late Triassic age; they are the teeth of otherwise nonbiomineralized jawless fish (Aldridge et al. 1986). Rarely, these phosphatic elements occur as natural assemblages reflecting the morphology and topology of the conodont tooth-set, albeit collapsed into two dimensions on the bedding plane. The Soom Shale preserves hundreds of bedding plane assemblages of conodonts, which can be seen on the shale surface with the naked eye. All are from the priniodontid order; those of the taxon Promissum pulchrum form a significant proportion of the fossils collected from the Lagerstätte (Aldridge et al. 2013). They are both the ...
During any anesthetic, especially during General Anesthesia, it may be necessary to place life sustaining, and life saving airway devices. Be aware that no dental restoration, cap, crown, bridge, implant, partial, denture or any other unnatural dental work present, is as sound or strong as natural dentition. It is thus possible that during placement of the aforementioned devices, and perhaps even more commonly, during involuntary emergence biting down, that the dental work can be damaged. Despite the anesthesiologist taking utmost care to protect your dentition, situations may arise, out of his / her control, that could lead to dental damage. Similarly, unsound natural dentition are prone to the same risks. We encourage our patients to disclose all dental work and dental conditions, so that optimal protection can be put in place. ...
Partial mandibulectomy is a procedure that involves the partial removal of the lower jaw. This procedure is most often used to treat oral cancers affecting the mandible. - Wag!
Mandible is the scientific term for the lower jaw. Whereas we humans have a lower jaw made of only a single bone (the dentary), penguins have a more complicated mandible made up of half a dozen different elements (the dentary, splenial, articular, prearticular, angular and surangular). These bones are all connected in penguins, though some…

I am indebted to my friend Mr. A. N. Leeds, of Eyebury, near Peterborough, for the opportunity of bringing under the notice of the Society a very interesting, although unfortunately imperfect, Dinosaurian jaw, recently obtained from the brick-pits in the Oxford Clay near the town named.. The specimen comprises the anterior and posterior extremities of the left ramus of the mandible, showing the alveoli of the teeth and the cavity for the articulation of the quadrate. The fractured surfaces are fresh, and it is thus evident that the present imperfect condition of the specimen is due to a blow from the pick of the workman by whom it was disinterred. When entire, its total length was probably about 1 foot. The anterior fragment (Pl. XI. figs. 1, 1 a)comprises the greater portion of the dentary bone, with the symphysis entire; while the hinder moiety (ibid. figs. 2, 2 a) includes the articular, and portions of the angular and surangular elements.. The dentary bone is somewhat roughened and pitted on ...

Segmental mandibulectomy is a surgical procedure involving removal of a segment of the mid-body of the mandible while preserving both the rostral and caudal mandible. This technique is indicated for benign oral tumors, such as acanthomatous ameloblastoma and either small or low-grade malignant tumors, of the mid-mandibular ramus. The overall complication rate following segmental mandibulectomy in dogs is 33%, including dehiscence and mandibular drift with associated malocclusion. Rim mandibulectomy is similar to a segmental mandibulectomy in terms of indications and technique; however, the ventral cortex of the mandibular ramus is preserved with a cresenteric osteotomy. Preservation of the ventral cortex of the mandible prevents mandibular drift and malocclusion associated with segmental mandibulectomy.. The overall complication rate following segmental mandibulectomy in dogs is 33%. The most common complications are wound dehiscence (17%) and short-term eating difficulties (up to 44% overall ...

Elephant shrews are small, quadrupedal, insectivorous mammals resembling rodents or opossums, with scaly tails, long snouts, and legs quite long for their size, which are used to move from one place to another like rabbits. They vary in size from about 10 to 30 centimetres (3.9 to 11.8 in), from 50 to 500 grams (1.8 to 17.6 oz). The short-eared elephant shrew has an average size of 150 mm (5.9 in). Although the size of the trunk varies among species, all are able to twist it about in search of food. Their lifespans are about two and a half to four years in the wild.[7][page needed] They have large canine teeth, and also high-crowned cheek teeth similar to those of ungulates.[8] Their dental formula is 1-3.1.4.23.1.4.2-3 Although mostly diurnal[9] and very active, they are difficult to trap and very seldom seen; elephant shrews are wary, well camouflaged, and adept at dashing away from threats. Several species make a series of cleared pathways through the undergrowth and spend their day ...
