Endodontics: Introduction

Introduction:
Definition of endodontology:
•form
•function
•health of the dental pulp and the periradicular tissues that surround the root(s) of teeth.
•injuries and diseases of the pulp and periradicular tissues and their prevention and treatment.
History:
1- Ancient root canal filling: Nabatean warrior in 2200 years ago
(around 200 BC), 2.5 mm metal bronze wire inside the root canal.
2-It was thought that the metal wire could prevent the tooth
warm from burrowing inside the canal.
3- The ancient Chinese also thought that the cause of the caries
is tooth warm.
4- Chinese used arsenicals to treat pulpitis by the year 200 AD.
Specific indications for RCT:
Every tooth is indicated for endodontic treatment, from central incisor to third molar.
The specific indications of endodontic treatment are:
•Teeth with irreversibly damaged or necrotic pulps, with or without clinical and/or radiographic signs of apical periodontitis.
•Teeth with no clear evidence of pulp disease, where pulp space is required for restorative procedure (e.g. post space preparation, preparation of overdenture abutments, tooth hemisection, crown preparation on mis-aligned teeth).
So, RCT can be provided for teeth with vital and non-vital pulp tissues.

Aim:
Endodontic or root canal treatment aims to preserve teeth in a healthy and functional condition by:
•removing diseased pulp tissue
•managing internal infection
•preventing its recurrence.

Method:
Instrumentation
Irrigation
Obturation
