Oligodontia
Oligodontia
Oligodontia (pronunciation: /ˌɒlɪɡoʊˈdɒntiə/) is a rare genetic condition characterized by the absence of six or more teeth, excluding the third molars. The term is derived from the Greek words oligos meaning few and odontos meaning tooth.
Etymology
The term "Oligodontia" is derived from two Greek words: oligos, which means "few", and odontos, which means "tooth". Thus, the term literally translates to "few teeth".
Symptoms
The primary symptom of Oligodontia is the absence of six or more teeth, which can occur in either the primary or permanent dentition. This absence is not due to extraction or any other dental procedure. Other symptoms may include small and misshapen teeth, delayed eruption of permanent teeth, and malocclusion.
Causes
Oligodontia is typically caused by mutations in the AXIN2, EDA, or MSX1 genes. These genes are involved in the development of teeth and other structures in the body. Mutations in these genes can disrupt the normal development of teeth, leading to Oligodontia.
Treatment
Treatment for Oligodontia typically involves a multidisciplinary approach and may include dental implants, orthodontics, and prosthodontics. The goal of treatment is to improve the function and appearance of the teeth.
