Posterior teeth Posterior teeth In dentistry, the term posterior teeth usually refers as a group to the premolars and molars, as distinguished from the anterior teeth, which are the incisors and canine teeth. The distinction is one of anterior (front of the body) versus posterior (rear of the body). The distinction holds in both the upper jaw (maxilla) and lower jaw (mandible). As a rough guide, it can be said that the anterior teeth are tailored to biting (breaking the food into chewable chunks) whereas the posterior teeth are tailored to chewing (comminuting the food into swallowable particles). Anterior teeth are inherently
Failure of eruption of teeth eruption has a genetic or familial background precursor as a cause. The prevalence is of PFE is about 0.06% in population. In this type of failure, teeth that are non-ankylosed fail to erupt in the mouth. These teeth do not have a precursor tooth that is blocking their path. These teeth tend to erupt partially but then fail to erupt as the time goes on. Profitt stated that only the posterior teeth are the ones to be affected and all the teeth which are distal to the affected tooth are also affected. Both permanent and primary teeth may equally be
