This subject is talking about : description of irrigation types of irrigant solutions use in endodontic treatment

1. Irrigation In
Edodontics
By:
Bushra Hussein Kheirbek

2. The main aim of the endodontic
therapy is
to disinfect the entire
root canal system, and
prevention of its re-infection
during and after treatment

3. The primary endodontic
treatment goal must thus
be to optimize root canal
disinfection and to prevent re-
infection

4. Irrigation solution
• Is a chemical solution used to dissolve
organic and inorganic matter and kill
microbes effectively
• the only way to impact those areas of the
root canal wall that are not touched by
mechanical instrumentation.

5. Functions Of Irrigating
Solutions
• Washing action

6. Functions Of Irrigating
Solutions
• Washing action
• Lubrication

7. Functions Of Irrigating
Solutions
• Washing action
• Lubrication
• Dissolve organic
And inorganic tissue

8. Functions Of Irrigating
Solutions
• Washing action
• Lubrication
• Dissolve organic
And inorganic tissue
• Kill bacteria and
yeast

9. Chemically Non Active
Materials
•Distilled water
•Normal saline

10. Normal Saline

11. Hydrogen Peroxide
Concentration 1-30%
Has antibacterial effect
Having bubble action

12. Sodium Hypoclorite
concentrations 0.5-5.25%.
Most important solution
Dissolve organic tissue only
Effectiveness depends on
temperature & concentration

13. Iodine Potassium Iodide

14. Chlorhexidine Digluconate
Concetration 2%
Has antimicrobial effect
Dissolve tissue
antimicrobial substantivity

15. Ethylene-Diamine-Tetra-Acetic Acid
(EDTA)
Concentration 17%
decompose the inorganic
component

16. Citric Acid
Concentration 1-50%
Smear layer removal

17. Interaction Between
Irrigation Solution
Loss of it’s
activity

18. Combination Products
Composition :EDTA + carbamide peroxide
root canal conditioner
•mixture of a tetracycline
isomer + acid (citric acid)+
detergent
•Rmoves smear layer
•Disinfect root canal
MTAD

19. Conclusion
• Successful root canal therapy depends on
thorough chemomechanical debridement of root
canal
• There is no single irrigating solution that alone
sufficiently covers all of the functions required
from an irrigant.
• Optimal irrigation is based on the combined use
of two or several irrigating solutions, in a specific
sequence.
