Oral health status, knowledge, attitude and practice of patients with heart disease

BACKGROUND: The aim of this study was to investigate knowledge, attitude and practice (KAP) of cardiovascular disease (CVD) patients about their oral health status. METHODS: In this cross-sectional study, we analyzed the data of 150 CVD patients that collected by a self-administered questionnaire consists of demographic characteristics and KAP. Oral health indicators calculated based on the results of oral examination by an expert dentist. RESULTS: CVD patients had an overall moderate level of knowledge and attitude, but their practice was lower than moderate. There were important associations between knowledge scores with gender, education, residential area and financial status, between attitude scores with education and residential area, and between practice scores with education and financial status. There were no associations between KAP and age, marital status or job. Significant positive correlations were found between KAP components. Significant negative correlations were found between oral hygiene index with knowledge and practice. CONCLUSION: The practice of heart disease patients about their oral health was poor, and declares that increasing awareness and attitude may not promote practice. Efficient programs are needed to promote oral health practice of adult populations in special groups. © 2016, Isfahan University of Medical Sciences(IUMS). All rights reserved

Evaluation of the Effect of Plasma Rich in Growth Factors (PRGF) on Bone Regeneration

Objective: Reconstruction methods are an essential prerequisite for functional rehabilitation of the stomatognathic system. Plasma rich in growth factors (PRGF) offers a new and potentially useful adjunct to bone substitute materials in bone reconstructive surgery. This study was carried out to investigate the influ-ence of PRGF and fibrin membrane on regeneration of bony defects with and without deproteinized bovine bone mineral (DBBM) on rabbit calvaria. Materials and Methods: Twelve New Zealand white rabbits were included in this randomized, blinded, prospective study. Four equal 3.3×6.6 mm cranial bone defects were created and immediately grafted with DBBM, PRGF+DBBM, PRGF+fibrin membrane and no treatment as control. The defects were evaluated with histologic and histomorphometric analysis performed 4 and 8 weeks later. Results: Adding PRGF to DBBM led to increased bone formation as compared with the control group in 4- and 8-week intervals. In DBBM and PRGF+fibrin membrane samples, no significant increase was seen compared to the control group. There was also a significant increase in the rate of biodegradation of DBBM particles with the addition of PRGF in the 8-week interval. Neither noti-ceable foreign body reaction nor any severe inflammation was seen in each of the specimens evaluated. Conclusion: Under the limitation of this study, adding PRGF to DBBM enhanced osteogenesis in rabbit calvarias. Applying autologous fibrin membrane in the de-fects was not helpful
