The canine teeth are able to withstand the tremendous lateral pressures from chewing. There is a single cusp on canines, and they resemble the prehensile teeth found in carnivorous animals. Though relatively the same, there are some minor differences between the deciduous (baby) mandibular canine and that of the permanent mandibular canine.
Animals where this occurs include antelopes, musk-deer, camels, horses, wild boar, some apes, seals, narwhal, and walrus. [6] Male dogs have larger canines with different contour than do females. [7] Humans have the proportionately smallest male canine teeth among all anthropoids and exhibit relatively little sexual dimorphism in canine tooth size.
Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]

One of the factors that complicate restorative work is over-eruption of teeth as there is now a reduced height between the upper and lower arch. The prosthesis won't be able to seat fully and the patient will appear to have a premature bite or appear 'high' in ICP. Other features that result in an unstable ICP are: Drifting of teeth; Tilting of ...
It is most commonly seen in school children. Dental subluxation is one of the most common traumatic injuries in primary dentition. Maxillary central incisors are the most commonly affected teeth. [10] [11] Some studies have proposed that the resilience nature of periodontium favours dislocation than fracture of the tooth itself. [12]
Occurs due to a localized and limited injury to the root surface or periodontium. It is a transient, self-limiting process of resorption that ceases after removal of the traumatic stimulus and is followed by healing of root surface, cementum , and periodontal ligament .
