Hypodontia
Hypodontia (pronounced: hi-po-don-sha) is a medical condition characterized by the absence of one or more primary or permanent teeth. The term is derived from the Greek words "hypo" meaning "under" and "odont" meaning "tooth".
Definition
Hypodontia is a form of dental agenesis, a group of conditions characterized by the developmental absence of one or more teeth. This can occur in the primary dentition (baby teeth), the permanent dentition (adult teeth), or both.
Etiology
The exact cause of hypodontia is not known, but it is believed to be a result of a combination of genetic and environmental factors. Some genetic conditions, such as ectodermal dysplasia and Down syndrome, are known to be associated with hypodontia.
Classification
Hypodontia is classified based on the number of missing teeth. If only one or two teeth are missing, it is referred to as hypodontia. If three to six teeth are missing, it is referred to as oligodontia. If all teeth are missing, it is referred to as anodontia.
Treatment
Treatment for hypodontia depends on the number of missing teeth and the patient's age and overall health. Options may include dental implants, dental bridges, or dentures. In some cases, orthodontic treatment may be needed to correct the alignment of the remaining teeth.
