consent before proceeding with treatment (Fig 22F).

Crown lengthening procedure allows more tooth structure to be exposed, making it
easier to isolate which lower the chances of microleakage in the future. In addition,
crown lengthening also allows for easier removal of carious lesions. A crown needs to be
supported on healthy tooth structure, if it rests on demineralised or carious structures,

caries can progress and re-infection of the root canal system will happen in the future. Dr.
Schilder often reinforced the idea that coronal seal is as important as apical seal.
Therefore, the need for pre-treatment isolation, crown lengthening surgery, post, core,

and crown should be discussed prior to initiating root canal treatment. The success of root
canal treatment depends on the ability to maintain both coronal and apical seal.
