Lack of evidence for the necessity of root canal obturation

Conclusion: Despite showing adequate root canal obturation radiographically, persistent bacteria could be identified in all teeth extracted. While perfect disinfection of root canals is mandatory, root canal obturation seems questionable as current materials have no antibacterial activity, do not stabilize the tooth, and cannot seal the canal system if a coronal restoration is missing.
