Vascular mechanism of spongious dental anesthesia.

By their mechanism of action local anesthesia methods are divided into diffuse and vascular. Anesthesias are vascular at arteriolo-capillary-venous system level. Besides more than 2-fold efficacy increase, circulatory mechanism also contributes to enhancement of cardiovascular system reactions.

[Aspiration test to intraseptal anesthesia of lower teeth].

Frequency of positive aspiration and value of pain threshold of lower posterior teeth after intraseptal anesthesia 0,4 ml 4% articaini with epinephrine 1:100 000 of low firstpremolar were studied on 48 volunteers. Positive aspiration with maximum sensitivity of this and neighbour teeth was observed in 43 cases.

[Vascular dental anaesthesias and their mechanism].

By their mechanism of action local anaesthesia methods were divided into diffused and vascular. Intraosseous, intraseptal and intraligamental anesthaesias are vascular ones at capillary-venous system level. Circulatory mechanism besides effectiveness increased more than 2-fold and also promotes enhancement of cardiovascular system responses.

[Intraceptal anesthesia of lower and upper teeth].

Effectiveness of intraseptal anesthesia for dental caries and its complications in 154 patients of different sex and ages was studied. Arterial pressure and heart rate were investigated in all patients before and after intraseptal injection with the help of automated monitor. Complete pain relief was observed in 135 patiensts, incomplete - in 12 patients. Intraseptal injection didn't act in 7 cases. There was no difference between the anesthesia on mandibula and maxilla. This was simple and predictable technique strong reaction of cardiovascular system occurred.
