As hackers are trying to break security seal, the microbial enemy tries to break both of coronal and apical seal.
Concomitantly, procedural errors act as a co-hackers that may lead to endodontic failure.
Therefore, dentists are in big challenge to obtain and to maintain sealing of the root canal system.
This is a 26 years old female patient that was referred to me seeking for retreatment of 16 tooth.
Clinical and radiographic (periapical & CBCT )examinations revealed the following;
•Severally curved mesial root.
•Missed MB2
•Two broken instruments in DB canal
• Ledged palatal canal at the apical third.
•No coronal and apical seal of the root canal system.
Based on previous data; the treatment plan was directed to the following procedures in an arranged manner;
1-Removal of the coronal carious tooth structure with pre endo build up.
2- Removal of old GP from both of MB, and palatal canals.
3-Removal of the broken instruments from the DB canal.
4- Cleaning and shaping of the MB, DB and Palatal canals.
5-Negotiation, cleaning and shaping of MB2.
6-Ultrasonic activation of the irrigating solution for 1 min in each canal.
7- Dryness of the root canal system.
8- Obturation of the root canal system using WVC utilizing warm GP and MTA Endoseal sealer .
