The human tooth have a lot of anatomical variation and adequate information of root canal anatomy is an important
factor in successfull root canal therapy. The purpose of this study was evaluation incidence of second canal in distal
root of inandibular first and second molars.
Materials & Methods:
In this descriptive invitro study, 100 extracted human extrated first and second mandibular molar used then; distal
roots resected from CEJ. After removal the pulp tissue, teeth stored in 30% hydrogen peroxid for 48 hours. Root
canal system was studied with dye penetration and serial horizontal sectioning methods.
Results:
There were 16% and 18% two canals in distal root of mandibular first and second mandibular molars. Different type
of canals in distal root of first mandibular molars were observed as follow: 10% type IV and 6% type II. Different
type of canals in distal root of second mandibular molars were as follow: 2% type IV, 2% type III, and 14% type II.
Conclusion:
With attention to the results of this study about incidence of second canal in distal root of mandibular molars careful
exploration is necessary for finding of extra canals.
Key words:
Second canal, distal root, first and second mandibular molar.Read More
