In external resorption cases, which type of incisors are also frequently affected?

External resorption is a condition characterized by the loss of tooth structure from the external surface of the tooth, often involving the roots. This phenomenon can be influenced by factors such as trauma, orthodontic treatment, or dental diseases. In the context of incisors, maxillary laterals are particularly susceptible to external resorption due to their anatomical and positional characteristics.

Maxillary lateral incisors can have variations in root morphology, including a slender root structure that may predispose them to resorption. Additionally, their relative location in the dental arch makes them more vulnerable to external forces, such as those from adjacent teeth or the surrounding bone. In orthodontic treatments, the movement of the maxillary laterals may increase the risk of resorption, especially if the teeth have experienced pre-existing conditions or trauma.

While other types of incisors and canines may be affected by external resorption, maxillary laterals stand out as frequently being involved in these cases due to their anatomical considerations and clinical behaviors. Therefore, the choice highlighting maxillary laterals as frequently affected incisors aligns with the understanding of the condition and the specific risks associated with this group of teeth.
