| pubmed-article:1303826 | pubmed:abstractText | The nerve fiber projection of the trigeminal ganglion cell to dental pulp, dentine and periodontal membrane was investigated with the technique of anterograde radioautographic neuroanatomical tracing (ARNT) in the rat. Results showed that the innervation in dentine and pulp was not uniform. The nerve endings were most numerous in the pulp horn, and in the tubular dentine of the cusp and cervical regions. In the periodontal membrane, both large- and small-diameter nerve fibers were found. And at least part of the innervation in the periodontal membrane was of trigeminal ganglion origin. | lld:pubmed |
