It is a good policy to sacrifice a little tooth structure inthe beginning which may obstruct a root canal than to try andmanipulate broaches around curves and angles. Not too muchemphasis can be placed upon this important step of the operationas many of the failures of root-canal treatment are directly trace-able to neglect of this initial 8 ,„£«.„!„ Fig. 87. — Calcification of the permanent upper teeth. I Hopewell-Smith.) An intimate knowledge of the anatomic structure of the indi-vidual teeth, especially in regard to the relationship of their pulpsto the surrounding dentinal walls is imperative. One should bemindful of the fact that the dental pulp is the remnant of the originalformative organ of dentin. In single-rooted teeth, i. e., incisors,canines and some of the premolars, the pulp occupies the centralpart of the tooth as regards its long axis, while in multi-rooted teethwith occasional exceptions in the third molars each root contains
