Endo instruments

1. ENDo_0 Prepared by : Osama Ahmad Almasry .. Level 7 Course Director : Dr . M. Altammimi

2. Goals of Root canal instruments To provide biologic environment to healing To develop canal shape to healing

3. Endo instruments :: 1 Hand instruments “ mouth mirror , Endo Explorer , Endo excavator , Endo plugger , Locking pliers , plastic instrument , Spreader “ 2 Instruments for pulp space preparation Group I Hand & finger operated instruments ( Barbed broach , Rasps , K files , Hedstrom file ) Group II Low speed instruments Group III Engine driven instruments of similar to group one

4. Types of files :: Traditional : carbon steel Stainless steel Niti : nickel titanium

5. Mouth mirror

6. Endo Explorer Two straight # very sharp end For Exploration of canal orifices

7. Endo Explorer

8. Endo spreader ( Hand ) ( Finger ) For compaction of gutta percha during obturation - Pointed tip - Hand or finger

9. Endo Spreader

10. Finger Spreaders Finger size # 15 Finger size # 20 Finger size # 25

11. Explorer vs spreader Explorer spreader

12. Endo Excavator - Much longer offset from long axis - Sharp to cut pulp tissue

13. Locking pliers Grooves to hold paper point And Gutta percha points

14. College Pliers Perry Pliers Fine tip for work within small pulp chamber

15. Plastic instrument

16. Endo plugger (hand ) - Flat tip - Depth orientation grooves - Hand or finger - Can be heated

17. Finger pluggers can be precurved to facilitate condensation. They are generally used deeper in the canal .

18.                                                                                                           Schilder Pluggers: Note that handles used in the School are NOT color coordinated and vary quite a bit . 

19. Heat Transfer Instruments Spreader – like design Designed for repeated heating

20.                                                Chamber roof is left in the the maxillary premolar (L). The other image (R) demonstrates what the access looks like immediately after un-roofing the chamber. The access needs to be completed with a tapered diamond .

21. Transfer sponge

22. Gates-Glidden Bur

23. Pesso Reamers /

24. Lentulo Spirals

25. Endo File Endodontic Files k-file #15-40 25mm length k-file #15-40 31mm length K-file #45-80 25mm length K-file #10 25mm length K-file #10 31mm length Hedstrom Files (H- file) #15-40

26. Barbed broaches

27. Endo Ruler

28. Gutta percha

29. Paper point

30. Sealer

31. REAMER The angle between the long-axis and the cutting blade is small, which is why preparation by reamer is effective only in rotating motion.

32. REAMER A reamer is manufactured from a triangular or square steel wire that is twisted to give the typical shape of a reamer.

33. K-FILE K-files are manufactured from square or sometimes triangular steel wire that is twisted to give the typical shape of a K-file. The angle The tip of the instrument is cutting which makes the K-file best suited for the preparation of straight canals. between the long-axis and the cutting blade is greater than in a reamer,

34. FLEXOREAMER : Flexoreamers are manufactured from a triangular steel wire that is twisted to give the typical shape of a reamer The angle between the long-axis and the cutting blade is small, and therefore preparation by flexoreamer is effective only in rotatory motion.

35. FLEXOFILE Flexofiles are manufactured from triangular (note!) steel wire that is twisted to give the typical profile of a K-file. The angle between the long-axis and the cutting blade is bigger than in reamers, which is why preparation by flexofile is effective both in rotating motion and in filing motion (up and down movement)

36. HEDSTR0EM FILE The angle between the long-axis and the cutting blade is close to right angle, which is why preparation by Hedstroem files is effective only when using a filing motion (up and down movement). Hedstroem files are manufactured from round steel wire by grinding.

37. NITI NiTiflex-files are manufactured from nickel-titan wire that is ground to give the typical profile of a K-file. The angle between the long-axis and the cutting blade is bigger than in reamers, and therefore preparation by NiTiflex-file is effective both in rotating motion and in filing motion (up and down movement).

38. Total of 6 radiographs will be taken and mounted for each case. Preoperative radiograph (without rubber dam). Working length radiograph (with rubber dam). Master apical file radiograph (with rubber dam). Master cone radiograph (with rubber dam). Intermediate radiograph (with rubber dam). Final radiograph (without rubber dam). A Diagnostic Endodontic Film requires that: The tooth is centered on the film. At least 5mm of bone beyond the apex of the tooth is visible. The image is as anatomically correct as possible.
