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 .
Hominid species that lived 1.8 to 1.3 million years ago. Continuing the pattern of hominid dental morphological evolution, ergaster had a less prognathic face, smaller dental arcade. The mandibular symphysis is also shown to have grown. In general the dentition, is very similar to that of Homo erectus.
The extraction of the deciduous canine may encourage the ectopic permanent canine to erupt. This interceptive treatment is recommended for children aged 10–13 with normal physiological spacing. This is supported by the Royal College of Surgeons England (RCS Eng) guidelines; based primarily on 2 studies: A case series, with no control group [20]
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 ...
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
Extant primates exhibit a broad range of variation in sexual size dimorphism (SSD), or sexual divergence in body size. [4] It ranges from species such as gibbons and strepsirrhines (including Madagascar's lemurs) in which males and females have almost the same body sizes to species such as chimpanzees and bonobos in which males' body sizes are larger than females' body sizes.
