Abstract
This research conducted for the purpose of :
1 - Set the acidic substance Hacwaljlas Aaonomr cement by measuring the changes that occur in hydrogen ion concentration ) (pH) of the cement before the end of the interaction , as well as several .
These changes compared with hydrogen Trkizaaon ( Ph ) for two of the cement lining materials for stuffing, as well as to kind of glass the Aaonomsmnt user base for stuffing .
2 - study the effect of filler material glass Aaonomr on the core cement to Adamic Adwag upper padded after prepared the different pits and using my evaluation histology way Baktraolga .
3 - Analysis of statistical data to set the existence of any possible relationship between mentioned previously .
Results:
The results showed a rapid increase in hydrogen ion concentration (ph) for all types of cement within fifteen minutes after mixing .
There have also been a slow increase in hydrogen ion concentration during the first sixty minutes and lasted up to eight hours for all types of cement .
Caused a filler material glass Aaonomr cement major histological changes in the dental pulp more than material Zinc Oxide Eginol .
I found a clear histological changes in the core of the year under the deep pits .
It also found a few changes under the surface pits .
As well as the medium changes under the deep pits lining .
Has also found that the thickness of the Ivory rest has no effect on the inflammatory response pulp Age padded and found that bacterial leakage of filler material glass Aaonomr within very few .
Summary :
1 - explained the hydrogen ion concentration measurements of shortening after the interaction that Material ( Ketak cm ) cement lining of the hole remains the hydrogen ion concentration have long been less than 3 .
2 - caused a filler material الجلاس Aaonomr Cement clear histological changes in the dental pulp hominid more than substance ( Zinc Oxide Eginol ) which has been used Control.
3 - Effect of degree of histological changes with filler material the Aaonomr cement pit depth , as well as the presence of cement lining of the hole.
4 - I found a strong relationship between the degree of inflammation dental pulp and bacteriological leak degree at the confluence of the materials used in the padding and the wall of the hole .
