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) 12017185Lertchirakarn/20024 groups, 10 teeth each In vitro
Key resultsThe 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.
