Abstract
This study was conducted to clarify influence Alheistologi and Alhustokimaaúa acetylcholine acid Slcelik to eat the roots of the teeth caused by shock Thtkih the soft tissue around the age which include gums and connective ligament around the teeth .
Therefore the study has been forty - five white male rat age of each of them four weeks, the mice were divided into three equal groups :
Group A: officer.
Group II: ( experimental ) caused her shock Thtkih .
Group III: (handle) caused the same shock with injected on the second day of a shock in a drug muscle acetylcholine acid Slcelik .
The samples were prepared in the following manner :
where the mice were sacrificed After Tkhaddrém to get on histologic slides after 7 , 14, 21 days from the occurrence of shock and then prepared for injection microscopic examination in two ways :
1 - extracted samples were materials Altklsah by acetic acid ethylene four dual - Amin and fixed in formalin and then placed inside the cubes of wax samples were cut entity Hraih order pigmentation of the following dyes :
- Dye Alheimatoxlin and Eocene .
- Dye Turaakrom ( three colors ) .
- Dye a chef acid reaction .
2 - The other samples Vantzaat them materials Altklsah by this acid , but proved in acetone and then placed inside lighted cubes of wax and cut in the form of segments in order pigmentation manner Jomora to the study of basal phosphatase enzyme activity .
The histological study showed the following results :
In the experimental group , which caused her shock Thtkih :
- The emergence of Mgoor eat on the outer surface of the root with the emergence of cells Naqdhat the Age causing this erosion within eroded Almgoor .
- The presence of large cells with multiple nuclei inside and outside eroded Almgoor .
- Crushing and smashing collagen fibers in the distance near of eroded Almgoor .
The treated group injected aspirin and found the following :
- The emergence of Mgoor abraded on the outer surface of the root but small if eroded compared Balmgoor of the second Balmujuah in the same periods.
- The emergence of connective ligament naturally age and the presence of its constituent cells on a regular basis .
- An increase in collagen fibers after 7 , 14, 21 days.
Depending on the results of the previous can be Astnaj as follows :
Giving acetylcholine acid Slcelik while eat the roots of the teeth leads to :
- Increase of collagen and connective tissue.
- A lack of depth and breadth in eroded Almgoor can be ascribed and interpreted for a property that acetylcholine acid Slcelik Anti inhibitor activity of prostaglandins material .
It is therefore recommended as follows:
- Avoid any shock Thtkih - on age and tissue that cause erosion of teeth roots .
- The use of acetylcholine acid Slcelik in diseases that affect the Sunni Rabat , causing erosion of the roots of the teeth as a medicine with other medicines assistant .
