Intrapulpal venous injection. Pilot study
Abstract
Relevance. The reason for the study was our histological specimen with intrapulpal dye injection from the monograph Anesthesia in Endodontics . Outside the pulp chamber, in the root canal, the ink is diffusely distributed throughout the vessels. There was a hypothesis about the vascular nature of intrapulpal injection.Aim. Тo prove vascular mechanism intrapulpal injection.Materials and methods. A randomized prospective pilot study was performed in 15 patients (9 men, 6 women) with 15 teeth vital pulpectomy. Traditional anesthesia conducted articaine 4% with epinephrine 1:100 000. When accessed in the pulpintroduced drop the same anesthetic. Heart rate was determined after 30 seconds for 3 minutes pulse oximeter MD 300.Results. There was expressed vascular reaction to intrapulpal introduction anesthetic with epinephrine. It has resulted in a sharp increase in pulse rate by an average of 11.3 beats /min, return to the original level after 3 minutes. Conclusions. Based on the results obtained, we assume the vascular-venous nature of intrapulpal anesthesia.
