The goal of all prosthetic treatment is to obtain a satisfying functional and esthetical oral status. Successful treatment outcome following prosthetic treatment relies on healthy hard tissues but also on healthy soft tissues. The aim of this study is to comparatively assess the clinical and biochemical parameters in gingival sulcus around the teeth received zerconium ceramic crowns with supra and sub-gingival crown margin position.

This study aimed to evaluate the clinical and microbiological effect
of fluoride in drinking water on the severity of chronic periodontitis
and its effect on the relationship between diabetes and periodontitis.

The failiers in fixed prosthodontics are very dangerous on the health of the periodontics.
This study aims to early diagnose the periodontitis caused by the failiers in the designe and
application of fixed prosthodontics.
The study sample consists
of 15 abutments in 15 patients aged (15-50) years with fixed
prosthodontics aged (1-3) years. (Average 2 years)
The results show the negative effect of bad prosthodontics on the absorbtion of the buccal
cortical plate due to very long margines of the prosthodontics, the leakage of the adhesing
cement and the beveldsholdermargines that play a role in changing the periodontal biofilm.
Four varieties of grape raisins where made in traditional way and
investigated for their chemical composition, mineral elements and total
antioxidanst capacity. Results reveals that there were significant differences in
the average percentage of m
oisture and carbohydrate between varieties,
whereas the protein, fat and ashes percentages were not significant. Results of
minerals analysis showed that blue raisins had the highest amount of Calcium,
phosphorous and potassium with a level of 66 mg, 193 mg and 989 mg in 100 g
raisins respectively. In addition, the total polyphenol contents by Folin-
Ciocalteau assay were higher in blue (257 mg) and red raisins (213mg) when
compared to the others varieties and vitamin C was 45mg/100g and 34 mg/100g
in blue and red raisins respectively. The antioxidant activity of raisins was
assessed by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay.
The amount of raisins needed to scavenge 50% of DPPH radical (EC50) was
similar for all varieties ranging from about 4.18 mg to 6.41 mg. Total
antioxidants capacity were in descending order blue >red > white > green
raisins. Therefore, the consumption of raisins is considered to contribute the
intake of antioxidants and minerals in Syrian diet .
The role of Interleukin-1 genes in the association between chronic periodontitis
and atherosclerosis has been under debate. The purpose of this study is to compare the existence of
interleukin1 genes polymorphism in the chronic periodontitis subjects with and without atherosclerosis.
