What method is used to fill the root canal of a maxillary lateral incisor?

The correct method for filling the root canal of a maxillary lateral incisor is laterally condensed. This technique involves using multiple smaller cones of gutta-percha that are compacted laterally against the walls of the root canal. It is particularly effective for achieving a dense and complete fill within the canal, which is essential for sealing any spaces that could harbor bacteria and lead to reinfection.

Laterally condensed filling allows for better adaptation of the gutta-percha to the irregularities and anatomy of the canal compared to a single major cone. This technique enhances the overall quality of the endodontic treatment by minimizing the risk of voids or gaps in the filling material. Additionally, it is commonly employed in smaller canals, such as those found in maxillary lateral incisors, where precise control and thorough filling are crucial.

Other methods, such as the use of a single large gutta-percha cone, may not provide the same level of sealing ability, and vertical condensation is typically reserved for wider canals where the space allows for such techniques. Laterally above condensed is not a recognized method in endodontic practice, which makes laterally condensed the optimal choice for this scenario.
