[Quantitative study of catecholamines in normal human dental pulp].
The purpose of this report was to study quantitatively the levels of catecholamines in human dental pulp by high-performance liquid chromatography (HPLC). 10 healthy teeth were selected from the extractions due to orthodontic reasons. The pulp of the teeth were obtained immediately after the extraction and samples were analyzed by means of HPLC for levels of dopamine, epinephrine and norepinephrine. The result showed that the concentration of norepinephrine in human dental pulp was 23.47 +/- 0.52 micrograms/g pulp tissue and dopamine was 19.17 +/- 1.03 micrograms/g pulp tissue.
