A diastema (pl.: diastemata, from Greek διάστημα, 'space') is a space or gap between two teeth. Many species of mammals have diastemata as a normal feature, most commonly between the incisors and molars .
Post-canine megadontia is a relative enlargement of the molars and premolars compared to the size of the incisors and canines. This phenomenon is seen in some early hominid ancestors such as Paranthropus aethiopicus .
The interpretation of the results shows that when there is a PAR score of more than 70% it represents a very high standard of treatment, anything less than 50% shows an overall poor standard of treatment and below 30% means that the patients malocclusion has not been improved by orthodontic treatment [29]
Canidae is a family of mammals in the order Carnivora, which includes domestic dogs, wolves, coyotes, foxes, jackals, dingoes, and many other extant and extinct dog-like mammals. A member of this family is called a canid; all extant species are a part of a single subfamily, Caninae, and are called canines. They are found on all continents ...
Canine space infections may occur by spread of infection from the buccal space. [2] Signs and symptoms of a canine space abscess might include swelling that obliterates the nasolabial fold . If left untreated, infections of this space will eventually spontaneously drain via the medial or lateral canthus of the eye, as this is the path of least ...
The book tackles the complex relationships between humans and dogs, and explores the themes of ethics, politics, and trans-species engagement. Drawing on memoirs, case law, and film, Dayan investigates the shared histories and struggles of dogs and humans, challenging established views of liberal humanism and offering new perspectives on ...
Hominid species that lived 3.9 to 2.9 million years ago. Compared to modern apes, A. afarensis and A. africanus have much smaller molars and canines, but they are still larger than those of humans’. [7] The smaller molars have been attributed to consuming seeds. [8] The jaws of both A. afarensis and A. africanus are very much prognathic. [9]
Another problem presents itself in the fact that it has been very difficult to assess which hominid [now "hominin"] represents the first member of the genus Homo. Without knowing this, it is not possible to determine which species of australopithecine may have been ancestral to Homo .
