Abstract

Farelerin kesici dişleri, pulpa odasına kadar oyularak bir yapay kavite meydana getirildikten sonra uygulanan çeşitli irritan maddelerin, pulpadaki kan dolaşımına etkisi incelendi. Aşağıdaki sonuçlar elde edildi:

1.Alkol, öjenol ve soğuk uygulamalarının kan dolaşımında herhangi bir etkisi bulunmamaktadır.

2.Adrenalin’in 1:1000 konsantrasyonu, damarları vazokonstriksiyon yaparak pulpada işemiye yol açmaktadır.

3.Fosforik asit, kan dolaşımının yavaşlamasında, tromboz oluşumunda, damarların genişlemesinde (dilatasyon), kanamanın meydana gelmesinde ve sonunda dentinin dekalsifikasyonunda rol oynamaktadır.

4.Sıcaklık uygulandığında, pulpada bir vazokonstriksiyon ardından bir vazodilatasyon, kan akışında yavaşlama, tromboz oluşumu ve kanama, yaklaşık 3 dakikalık bir süre içinde gerçekleşmektedir.

Keywords

vazokonstriksüyon, tromboz, demineralizasyon

Blood Circulation in Dental Pulp

Abstract

After the incisors of rats were drilled to the pulp chamber to create an artificial cavity, the effects of various irritant substances on the pulp circulation were observed. The following results were obtained:

1.Alcohol, eugenol, and cold applications had no effect on the blood circulation.

2.The 1:1000 concentration of adrenaline caused vasoconstriction in blood vessels and ischemia in the pulp.

3.Phosphoric acid plays a role in slowing down the blood circulation, the formation of thrombosis, dilation of blood vessels, the occurrence of bleeding, and ultimately the demineralization of the dentin.

4.When heat is applied, a vasoconstriction in the pulp is followed by vasodilation, slowing of the blood flow, thrombosis formation, and bleeding within approximately 3 minutes.

Keywords

vasoconstriction, thrombosis, demineralization
