background: recently, there has been interest in non‑mammalian collagen sources such as fish collagen in the development of biomatrices and scaffolds for periodontal regeneration. in the present study, a novel collagen barrier membrane of fish origin was assessed in the treatment ofperiodontal intra‑bony defects. materials and methods: ten systemically healthy chronic periodontitis patients hav...

background: chewing gum is a habit practiced regularly by a relatively high proportion of individuals in many countries including india, and its use has increased within the last decade. the aim of this study was to determine the effects of sugar-free and sugar chewing gums on plaque deposition. materials and methods: the study is a double blind clinical trial involving 16 healthy volunteers (d...

BACKGROUND/AIMS Chlorhexidine (CHX) spray has proven to be an easily applicable method for the chemical control of plaque in elderly and handicapped patients. A randomized double-blind cross-over placebo-controlled trial was undertaken to compare the effects of 0.2% CHX spray applied once or twice daily on the plaque and gingival indexes in 13 institutionalized elderly patients. METHOD The st...

BACKGROUND The aim of the present study was to evaluate the effect of adjunctive chlorhexidine (CHX) mouthrinse on gingival crevicular fluid (GCF) MMP-8 and TIMP-1 levels in plaque-associated gingivitis. METHODS A total of 50 gingivitis patients were included in the present study. In addition to daily plaque control, CHX group rinsed with CHX, while placebo group rinsed with placebo mouthrins...

BACKGROUND The influence of donor-transmitted coronary atherosclerosis (DA) on plaque progression during the first year after cardiac transplantation (Tx) is unknown. METHODS Serial 3-dimensional intravascular ultrasound (IVUS) studies were performed within 8 weeks (baseline; BL) and at 1 year after Tx in 38 recipients. On the basis of maximum intimal thickness (MIT) at BL, recipients were di...

objective: microbial plaque is among the main etiologies of periodontal disease, and tooth brushing with toothpaste is the most commonly used method of plaque control. this study aimed to compare the efficacy of tooth brushing with and without three different dentifrices.   methods: thirty dental students were randomly selected to participate in this clinical trial and were asked to refrain fro...

BACKGROUND AND PURPOSE The purpose of this study was to determine the accuracy of a risk index in symptomatic or asymptomatic carotid stenoses. METHODS Consecutive patients presenting 50% to 99% carotid stenoses were included. A semiautomated gray scale-based color mapping (red, yellow, and green) of the whole plaque and of its surface was achieved. Surface was defined as the region located b...

Although intensive lipid lowering by statins can enhance plaque stability, few data exist regarding how early statins change plaque composition and morphology in clinical setting. Therefore, to examine early changes in plaque composition and morphology by intensive lipid lowering with statins, we evaluate coronary plaques from acute coronary syndrome (ACS) before and 3 weeks after lipid lowerin...
