OPERATIVE CAUSES OF ENDODONTIC FAILURE

Gutta-Percha (GP) cone disinfection with Sodium Hypochlorite (NaOCl) is a rapid chairside procedure performed immediately before obturation:

1-Concentration: Use 2.5% to 5.25% NaOCl.
2-Contact Time: Immerse the GP cones for 1 minute (60 seconds) to eliminate surface pathogens (e.g., Enterococcus faecalis).
3-Rinse: Flush with 70% Isopropyl Alcohol or Sterile Saline to remove residual sodium chloride crystals and chemical residue.
4-Dry: Gently dry with Sterile Gauze before root canal insertion.

🔴BIO CERAMIC SEALER🔴

١-يعني ايه؟

-Its hydraulic calcium silicate based sealer

٢-بيعمل ايه؟
-Hydrophilic material..so,slightly expansion by bonding fluids (in Dentinal tubules) forming caoH ,,hydroxyapatite crystals.

عشان كده مش بعمل completely dryness of canals by paperpoints

٤-اهم مميزاته؟
- flowbility..
-Biocompatibility

٥-امتي بستخدمه؟

-Severly curved rootcanal.
-Double curved rootcanal.
-Difficult accessibility teeth (upper or lower 7&8)
-Anatomical complex (C shaped canal)
-Canal with broken file bypass.

٦-اكتر عيوبه؟
-Hard to remove for retreatment specially, if you fill canal with bioceramic sealer only without guttapercha.
٧-ازاي بستخدمه؟
-because, flowbility of bioceramic sealer, so must have experience to use it to avoid overextension beyond apex.
-Tip of biocer. Sealer shouldn’tbe locked inside the r.canal ..but, free so can do withdrawal outside with injection.

٨-طريقه الحقن؟
TWO WAYS;
1-for inexperience
Inject only in coronal -1/3 of canal then use mastercone to push sealer and pump in all sides of canal.
2-traditional ;
Adjust stoper shorter than 2-3 mm from full W.L then withdrawal slowly outside.

Bioceramic sealer used in special cases like mention before with accurate selected master cone Guttapercha.

IRRIGATION PROTOCOL AS A ESSENTIAL STEP IN RCT ..

استكمالا لموضوعنا الاساسي WHY ENDO FAIL??

(Irrigation protocol fe comments)

25/03/2026

🔴 Top 3 causes of root canal failure;

1-Missed canal . ( short term faliure)
يعني اعراض فشل حاله اندو متعالجه من سنه الي ٣سنين بحد اقصي.

👉How to avoid?
اهتم بخطوه ال ACCESS جداا
احنا دايما بندور علي missed canal الي ان يثبت العكس.

2-Insufficient RC disinfection;
يعني اعراض فشل حاله اندو ..with agood obturation x ray

👉How to avoid?

اعمل + اهتم بخطوه Irrigation protocol

3-delay or missing coronal seal

الحل بسيط جداا 🙂
seal the canal’s or***ce after obturation immediately..

The truth about endodontics

The truth about endodontics

🔴حقائق لازم تعود نفسك عليها وانت شغال RCT. 🔴

1-Try to train yourself to finish RCT in single visit whenever possible ( always keep this as your goal)

2-Re treatment cases always couldbe finished in single visit ( special cases)

3-At obturation step.. ( lateral condensation)
*The spreader size larger than the auxiliary cone.,
**Sealer only apply on master cone .
***When you cut the Gp, always leave it at the or***ce level or at least 2 mm below it, so you can place flowable composite to achieve agood coronal seal.

4-Try to complete the coronal restoration in the same visit as obturation ,to ensure aproper coronal seal together with the apical seal as coronal seal affect on success rate of rct.

🟥 To avoid instrumentation mishapes!!

-Before rotary shaping canal:
1-canal scouting (file 10 k)
2-Negotiation to patency.
3-Coronal flaring ( or***ce opener)
4-Determination of W L
5-Glide path preparation (till file 20 )

🔴 SHOULD THE CROWN COVERAGE BE REMOVED OR KEPT DURING RE RCT??

دايماا بننصح removing the existing crown عن اني اعمل access through it

ليه!!
ده بيخليني اتجنب risk of iatrogenic errors
PERFORATION
الافضل نشيل الكراون as single unit
وبستخدمه كمؤقت بين الزيارات ..

احتماليه اني اشيل الكراون بتزيد لو not clinically perfect
Such as, in cases of defective restorations as open margins
وبالتالي
1-caries beneath the crown.
2-periodontal inflammation ( periodontal pocket mimicking endo pain.

**Rationale for crown removal in re rct;

1-Elimination of potential sources of infection , including micro leakage beneath defective crowns.
2-Improved visualization and straight line access to the pulp chamber and root canals .
3-Reduced risk of perforation and missed canals.
4-Better assessment of the remaining tooth structure and ferrule effect for restorability.
