Interradicular branches terminate in the PDL at which locations?

Explanation:
Interradicular branches are the nerve fibers that supply the periodontal ligament specifically between the roots of a multirooted tooth. They travel to the PDL in the furcation area—the space where the roots diverge—and terminate there. That furcation region is the key site where these branches end, distinguishing them from nerves that go to the pulp at the apex or from tissues inside the tooth (pulp chamber) or the surrounding bone (buccal plate). Therefore, their termination in the PDL occurs at the root furcations, not at the apex, pulp chamber, or buccal plate.
