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]
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 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]
Toxocara canis (T. canis, also known as dog roundworm) is a worldwide-distributed helminth parasite that primarily infects dogs and other canids, but can also infect other animals including humans. [ 1 ] [ 2 ] The name is derived from the Greek word toxon 'bow, quiver' and the Latin word caro 'flesh'. [ 3 ]
Ardipithecus was a more primitive hominid, considered the next known step below Australopithecus on the evolutionary tree. The A. anamensis find is dated to about 4.2 million years ago, the Ar. ramidus find to 4.4 million years ago, placing only 200,000 years between the two species and filling in yet another blank in the pre- Australopithecus ...
