Filter by:A clinical and radiographic evaluation of autogenous periosteal pedicle graft in comparison with collagen membrane for management of periodontal intrabony defects.
The present study aimed to evaluate the effects of enamel matrix derivatives either alone or combined with autogenous bone graft applied to intrabony defects in chronic periodontitis patients on clinical/radiographic parameters and gingival crevicular fluid transforming growth factor-β1 level and, to compare with open flap debridement. Our hypothesis is to test whether the use of autogenous bone graft and enamel matrix derivative combination in the treatment of intrabony periodontal defects enhance the clinical, radiographic and biochemical parameters in comparison to the use of open flap debridement alone.
Periodontitis, a bacterial dental biofilm based infectious disease, is a chronic inflammatory disease of the periodontium which results in irreversible destruction of supporting structures of the teeth such as periodontal ligaments, connective tissues, cementum and alveolar bone. More than 700 species of bacteria are estimated to be found in the sub-gingival dental biofilm in which periodontopathogens are found to be responsible in initiating periodontal disease. Chronic periodontitis, although termed as 'chronic', starts as an acute inflammation. Low levels of bacteremia and endotoxins provides a stimulus for the systemic inflammatory response. In periodontitis, the interaction of lipopolysaccharide (LPS) from gram-negative bacteria with host cells initiates the secretion of cytokines and the expression of cell adhesion molecules in gingival tissue which leads to loss of alveolar bone and connective tissues supporting the teeth. In the management of chronic periodontitis, non surgical periodontal therapy (NSPT) which includes oral hygiene instruction (OHI), scaling and root planing, is administered to improve clinical parameters as well as controlling the bacterial count responsible in initiating the disease and the resultant inflammatory response. Success of the treatment can be analyzed when the clinical parameters, counts of the microbes is reduced and inflammatory response is controlled. Studies which have evaluated the microbiological and immunological response following NSPT clearly demonstrates an improvement in clinical parameters, reduction in inflammatory mediators present as well as a decrease in microbial count. OHI which includes tooth brushing and inter-dental cleaning is found beneficial in removing microbial plaque, thus, preventing periodontal diseases such as gingivitis and periodontitis. Studies have evaluated the role of OHI on clinical and immunological parameters and microbiological profiles of periodontal maintenance subjects, while none of them evaluated its role alone in the management of chronic periodontitis subjects. Therefore, the purpose of the following investigation was to compare the changes in the clinical parameters, inflammatory mediators as well as level and frequency of detection of periodontopathogens that take place after 3-months of NSPT versus OHI and to evaluate if clinical parameters have an effect on these inflammatory mediators and microbiological changes.
The oral cavity is mostly influenced by general health. The oral microbiota which is as complex as the gastro-intestinal or vaginal microbiota are considered to be difficult therapeutic targets. The effects of probiotics in different fields of health care have resulted recently in the introduction of probiotics for oral healthcare. Probiotics have been clinically proved effective in different fields of oral healthcare such as halitosis, oral candidiasis and tooth decay. They have also been inducted in the field of periodontal healthcare because of the current views on the etiology of plaque- related periodontal inflammation.
It is common practice to carry out the therapy of periodontal diseases in two phases. In a first, non-surgical phase, bacterial deposits on tooth surfaces (plaque and calculus) are removed using a cleaning method called "scaling and root planing" (SRP). After three to six months the case is evaluated and, if necessary, further treatment is provided, usually taking a more aggressive, surgical approach. Beneficial effects of adjunctive systemic antibiotics on clinical outcomes have been shown repeatedly but specific indications for antibiotics in subgroups of diseased patients, and the optimal timing of antimicrobial therapy, continue to be issues of a long lasting controversy.This study assessed the differential outcomes of periodontal therapy supplemented with amoxicillin-metronidazole during either the non-surgical or the surgical treatment phase.
This is a split-mouth, double-blind randomized controlled trial. Computerized linear radiographic measurements were used to detect infrabony defects treated with open flap debridement (OFD) or OFD associated with enamel matrix derivative (EMD), after 24 months. Ten patients presenting 2 or more defects were selected (43 defects). An individualized film holder was used to take standardized radiographs at baseline and after 24 months. Images were digitized and used to measure the distances from the cemento-enamel junction (CEJ) to the alveolar crest (AC), CEJ to the bottom of the defect (BD) and infrabony defect angle.
In the present clinical study including chronic, aggressive periodontitis and healthy individuals, the investigators aimed to determine the RANKL, osteoprotegrin (OPG), Interleukin-1 (IL-1β), IL-10, IL-1β levels in gingival crevicular fluid(GCF) before and after surgical periodontal treatment and search out the relationship of clinical parameters with these cytokine levels.
Periodontitis is a multifactorial disease that can lead to the destruction of supporting tissues of the teeth resulting in pocket formation, recession or both. Since the primary etiological factors for periodontal disease are bacteria in supra and sub gingival biofilm, efforts for disease prevention and treatment are mainly focused on pathogen reduction and strengthening of epithelial barrier, thus contributing to decreased susceptibility to infection. Due to emergence of antibiotic resistance and frequent recolonization of treated sites with pathogenic bacteria, there was need for a new treatment paradigm to be introduced to periodontal disease. The need was fulfilled by the introduction of Probiotics and Bacterial Replacement Therapy. The term probiotic is derived from the Greek, meaning "for life" are microorganisms proven to exert health promoting influences in humans and animals. Food and Agriculture Organization and WHO have stated that there is potential for probiotic foods to provide health benefits and that specific strains are safe for human use.
1. Are adipokines involved in pathogenesis of periodontal disease in diabetic patients? 2. Does their level change after periodontal therapy?
The primary objective of this study is to assess the short-term immune response of type-2 diabetics with generalized chronic periodontitis (GCP) to nonsurgical periodontal treatment. The investigators hypothesize that type-2 diabetes exacerbates the disruption of DC (dendritic cells)-mediated immune homeostasis associated with periodontitis.
