title: Finding Small Root Canals.
abstract: One of the main reasons for failure of teeth that have been root treated is the inability to locate and clean canals that are very small or not identified by the clinician. In contemporary practice the use of dyes, such as methylene blue, or magnificatin, such as the microscope are used rotinely in these situations to find the canal orifice in the pulp chamber. Prior to this, other more aggressive methods have been used, such as that identified in 1920.
