Mouth | Odontologie | Dentition (Disease)


Dentition is characterized by the development and eruption of the teeth and their arrangement in the mouth. In particular, the characteristic arrangement, kind, and number of teeth at a given age.

Causes and Risk factors

Clinically, there are three dentitions. The primary dentition consists of 20 teeth in all: ten upper and ten lower teeth. Primary teeth may also be called baby teeth, deciduous, milk, or lacteal teeth. Primary teeth begin to appear at about age six months and are entirely replaced by about ages 12 - 13. The mixed dentition is composed of both primary and permanent teeth. It starts with the eruption of the first of the permanent teeth at about age six, and ends with the loss of the last of the deciduous teeth at about the age of 12-13 years.

The permanent dentition is composed of 32 teeth in all, 16 upper and 16 lower. Half of a dental arch (primary or permanent) is called a quadrant. The permanent teeth that replace deciduous teeth are called succedaneous teeth. Succedaneous literally means to replace. In dental science, permanent teeth that replace deciduous teeth are called successional teeth. Permanent molars, which replace nothing are called accessional teeth.

Diagnosis and Treatment

No treatment is needed for simple dental eruption. Acetaminophen and/or nonsteroidal anti-inflammatory medications are usually administered. If there is a severe infection, antibiotics may be prescribed, and sometimes the affected wisdom tooth extracted. ...
