Maxillary lateral incisor agenesis

Maxillary lateral incisor agenesis (MLIA) is a dental condition characterized by the absence of one or both maxillary lateral incisors, the second teeth from the middle in the upper jaw. This condition can be either unilateral, affecting one side, or bilateral, affecting both sides.

Etiology

The exact cause of MLIA is not fully understood. However, it is believed to be a result of a combination of genetic and environmental factors. Some studies suggest a strong genetic component, with the condition often running in families. Environmental factors such as maternal smoking during pregnancy, use of certain medications, and exposure to radiation have also been associated with an increased risk of MLIA.

Prevalence

MLIA is a relatively common dental anomaly, with a prevalence ranging from 0.8% to 2.6% in the general population. It is more common in females than in males, and more common in Caucasians than in other racial groups.

Diagnosis

Diagnosis of MLIA is typically made through a dental examination and imaging studies such as dental radiographs. The absence of one or both maxillary lateral incisors on these images confirms the diagnosis.

Treatment

Treatment for MLIA depends on the individual patient's needs and may include orthodontic treatment, dental implants, or prosthetic replacement of the missing teeth. The goal of treatment is to improve the patient's oral function and aesthetics.

Impact

MLIA can have a significant impact on a person's quality of life. It can affect oral function, making it difficult to eat and speak properly. It can also affect a person's appearance and self-esteem, particularly if the missing teeth are in the front of the mouth.
