Size Of Teeth Microdontia Macrodontia

MICRODONTIA Microdontia: It is defined as the size of theeth which is smaller than normal (or) outside the normal range of teeth size. Microdontia is again divided into 3 types: True Generalized Relatively Generalized Involving a Single Tooth

Number Of Teeth • • Anodontia Supernumerary Teeth Pre-Decidious Teeth Post-Permanent Teeth

Pre-Decidious Teeth • Deciduous teeth, otherwise known as reborner teeth, baby teeth, temporary teeth and primary teeth, are the first set of teeth in the growth development of humans and many other mammals. In some Asian countries they are referred to as fall teeth as they will eventually fall out, while in almost all European languages they are called milk teeth. They develop during the embryonic stage of development and erupt—that is, they become visible in the mouth—during infancy. They are usually lost and replaced by permanent teeth, but in the absence of permanent replacements, they can remain functional for many years.

Anodontia • In dentistry, anodontia, also called anodontia vera, is a rare genetic disorder characterized by the congenital absence of all primary or permanentteeth. It is associated with the group of skin and nerve syndromes called the ectodermal dysplasias. Anodontia is usually part of a syndrome and seldom occurs as an isolated entity.

Supernumerary teeth • Supernumerary teeth can be classified by shape and by position. The shapes include: • Supplemental (where the tooth has a normal shape for the teeth in that series); • Tuberculate (also called "barrel shaped"); • Conical (also called "peg shaped"); • Compound odontoma (multiple small tooth-like forms); • Complex odontoma (a disorganized mass of dental tissue)[
