| Title |
Endodontically Treated Roots with Ketac-Endo Sealer are Stronger and More Resistant to Vertical Root Fracture Compared to Roots Sealed with AH Plus Sealer |
| Clinical Question |
For a patient with a need for root canal treatment, will the use of Ketac-Endo root canal sealer make the root more resistant to vertical root fracture compared to the use of AH plus sealer? |
| Clinical Bottom Line |
For a patient with a need for root canal treatment, obturation using Ketac-Endo sealer made the roots stronger and more resistant to vertical root fracture compared to obturation with AH plus sealer. Thus, the use of Ketac-Endo sealer is preferred when forces that could cause vertical root fracture are anticipated. |

| #1) 12017185 | Lertchirakarn/2002 | 4 groups, 10 teeth each | In vitro | | Key results | The resistance to vertical fracture in roots of mandibular incisors treated endodontically using Ketac-Endo sealer is found to be about 30% greater than those sealed with AH plus and no significant difference was found between roots filled with Ketac-Endo and uninstrumented roots. There was a significant difference (p < 0.05) in forces needed to cause fracture of a sealed root with Ketac-Endo (317.1 ± 32.0 N) compared to roots sealed with AH plus which fractured at forces equals (246.9 + or - 23.6 N). | |

Comments on
The Evidence |
Validity: The teeth in all groups were treated with the same technique using different sealers and a similar force was applied until fracture acquired. All teeth were mandibular incisors and follow-up studies should ensure that this finding can be generalized to other teeth such as mandibular molars.
Perspective: This comparative study supports the conclusion that Ketac-Endo sealer made the roots more resistant to vertical fracture. However, the study was done on mandibular incisors only, which are single rooted.
|
| Applicability |
The result of the study would be of interest to the dentist when an endodontic treatment of a tooth is indicated and the root is weak and susceptible to vertical fracture. |
