Chronic periodontitis (CP) is an inflammatory disease, characterized by gingivitis, and affecting tooth supporting tissues, forming periodontal pockets with associated attachment loss, alveolar bone resorption. It is common in adults, but can also occur at any age. The rate of disease progression may be influenced by local, systemic conditions, and/or environmental factors that alter the normal host response to bacterial plaque, and affect the susceptibility to disease.It is suggested that periodontitis is partially associated by genetic factors, that many genes are involved in inflammation susceptibility, mainly include the vitamin D receptor (VDR) gene that is implicated in bone metabolism and the host immune response. 80 Syrian subjects were recruited for vitamin D receptor gene polymorphism study, and allocated in two groups: 50 diagnosed with CP and mean age was (64 ± 0.722) years, 30 matched controls. DNA was isolated from peripheral blood cells, and genotyping was performed by polymerase chain reaction (PCR) method and restriction fragment length polymorphism analysis (RFLP) by using FokI enzyme. By using Chi square test, no significant differences were found between the study groups in the frequencies of alleles and genotypes at FokI position of VDR gene, age and sex. These findings suggest that the investigated factors are not associated with periodontal disease in this studied sample of Syrian population.

Chronic Periodontitis is accompanied with subacute systemic inflammatory responses and a procoagulant state which manifests in changes of some serological vascular thrombotic markers levels. This study aimed to evaluate several vascular thrombotic markers levels in patients with chronic periodontitis.
Recent studies has focused on the impact of periodontal disease on the general health like cardiovascular disease and hypertension and their interactions. We aimed to study several vascular thrombotic markers levels in patients with chronic periodo ntitis and hypertension. Periodontitis in hypertensives was associated with an elevation in platelets count and fibrinogen concomitantly with an increase in blood glucose levels and body mass index,in addition to greater pocket probing depth and clinical attachment loss, compared with periodontitis only.These results shed the light on periodontitis as a risk indicator for hypertension and thrombotic propensity in susceptible individuals.
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.
Background& Objective: The success of implants is based on the quantity and height of the alveolar bone which reduce in the patients with chronic periodontitis.The purpose of this study was: to estimate the success of short implants activated by pl asma rich in growth factors in the posterior areas of bone resorption following chronic periodontitis and radiographic study of the crestal bone height.
Oral complications are common in patients with cancer who undergo chemotherapy treatment. Not all patients are at equal risk for developing oral complications. A number of variables have been identified that bear on both the frequency and severity of oral problems associated with therapy. These can be divided into those that are associated with the patient and those that are related to the treatment regimen. In this study we have studied the effect of patient age and gender on the oral complications in group of patients who undergo chemotherapy treatment. We conclude that aging can affect some oral complication chemotherapy like xerostomia and taste changes whereas gender has it effect on pain and oral sence disorders mainly in males.
