Endodontics: Part 9 Calcium hydroxide, root resorption, endo-perio lesions

P Carrotte¹

Calcium hydroxide is used in both the preservation of the vital pulp and the disinfection of the prepared root canal system.
To achieve success in direct pulp capping a strict aseptic regime must be followed.
Various forms of root resorption, their aetiology and treatment, are considered.
The Simon, Glick and Frank classification of endodontic/periodontic lesions is presented and discussed.

For more than 70 years calcium hydroxide has played a major role in endodontic therapy, although many of its functions are now being taken over by the recently introduced material MTA. Calcium hydroxide may be used to preserve the vital pulp if infection and bleeding are controlled; to repair root fractures, perforations, open apices and root resorptions. Endo-perio lesions are complex and the correct diagnosis is essential if treatment is to be successful. However, root canal treatment will always be the first phase in treating such lesions.
