Key Points
-
Root filled teeth are often compromised by incomplete root formation, secondary caries around posts, inappropriate post space preparation, and internal resorption.
-
Traditional methods of restoration using metal posts and pins are often unsatisfactory.
-
Instead of waiting for the formation of a calcific bridge during apexification, mineral trioxide aggregate can be placed as an immediate apical seal.
-
Weakened roots can be reinforced using dentine bonding agents, composite resin and quartz-fibre posts.

Weakened anterior roots – intraradicular rehabilitation
Abstract
This paper highlights the fact that many anterior teeth requiring restoration are severely weakened having wide, flared canal spaces, and thin dentinal walls that are prone to fracture. Traditionally these teeth have been restored using metal posts and are often unsuccessful because of lack of retention or root fracture. This paper describes how mineral trioxide aggregate (MTA) can be used to form an immediate apical seal rather than waiting months for apexification. Weakened roots can be reinforced using dentine bonding agents and composite resin and if insufficient coronal tooth structure is present a quartz-fibre post can be placed to retain a composite core.
