Although Er:YAG lasers are promising in treating periodontitis, the results of this study favor finishing SRP with hand curettes. Moreover, as there is a similar tendency between micro-organism and leukocyte count changes, leukocyte counts may be used as chairside marker to evaluate the efficacy of SRP.
The association between periodontal and cardiovascular disease has received considerable attention. Studies have demonstrated a higher incidence of atherosclerotic complications in patients with periodontal disease. Tissue factor (TF) has been known as a key initiator of the coagulation cascade, and the TF pathway is the primary physiological mechanism of initiation of blood coagulation. Recently, it has been shown that the circulating pool of TF in blood is associated with increased blood thrombogenicity in patients with coronary artery disease (CAD). Various tissues and saliva have been known to have TF activity. Consequently, the aim of this study was to investigate plasma TF levels and TF activity of saliva in periodontitis patients with and without diagnosed CAD. Twenty-six patients with a diagnosis of CAD and 26 systemically healthy patients were examined in the dental clinic, and the Community Periodontal Index Treatment Needs (CPITN) scores were recorded. Plasma TF levels were determined using commercially available ELISA kit. Salivary TF activities were determined according to Quick’s one-stage method. Plasma TF levels were significantly increased in patients with CAD when compared with the control group. There was no difference in salivary TF activities between the 2 groups, but there was a strong and negative correlation between salivary TF activities and CPITN indexes in both groups. In order to determine the possible role of TF activity as a salivary marker in CAD and periodontitis and to fully understand the negative correlation between salivary TF activities and CPITN, TF activity of gingival crevicular fluid that may also affect saliva can be evaluated.
Since periodontitis is a chronic and inflammatory disease, a number of hypotheses have proposed that it has an etiological or modulating role in cardiovascular disease (CVD). This study aimed to ascertain the changes in the plasma levels of C-reactive protein (CRP) and protein C (PC), a natural anticoagulant also having an anti-inflammatory effect, in patients who have mild-to-severe periodontitis with or without CVD. The test group consisted of 26 patients with CVD and chronic periodontitis and the control group consisted of 26 patients with chronic periodontitis and no systemic disease. In both groups Community Periodontal Index of Treatment Needs scores were recorded and blood samples were collected. CRP levels were significantly high and PC activity was significantly low in the test group compared to the control group (p < 0.001). There was a negative correlation between tooth loss and PC and between CRP and PC. How PC is affected by the inflammatory events and its association with CRP is an active area of investigation.
Serum total sialic acid (sTSA) has recently been shown to be a cardiovascular risk factor. However, there is little information about the role of sTSA and TSA in saliva in periodontitis, a chronic and inflammatory disease known to be a risk factor for cardiovascular disease (CVD). We aimed to investigate the changes in sTSA and TSA levels in saliva in patients having both periodontitis and CVD versus periodontitis patients without diagnosed CVD. The study group consisted of 26 patients with proven periodontitis and 26 controls with no diagnosed systemic disease but periodontitis. sTSA and saliva TSA levels were determined by the thiobarbituric acid method, and C-reactive protein (CRP) was evaluated by the nephelometric method. The severity of periodontitis has been determined by the community periodontal index of treatment needs (CPITN). TSA in blood and saliva and CRP levels in blood were significantly increased in CVD patients compared with the control group. CPITN ranged from 2 to 4 in both groups. Significant and positive correlations were found between sTSA and saliva SA levels in patients and controls and between tooth loss and TSA both in blood and saliva. Therefore, TSA in saliva may be a useful marker similar to sTSA in CVD patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
