Q

The cementum joins the enamel near the middle third of the root of the tooth; the cementoenamel junction is somewhat variable. It may extend precisely to the termination to the termination of the enamel, it may extend beyond the cervical termination of the enamel or it may fail to extend to the enamel.
(TRUE OR FALSE)
