Filter by:Objective The aim of this study was to test a protocol for the extraction of high quality genomic DNA from saliva samples obtained with mouthwash and taken from patients with periodontal disease. Materials and methods Saliva samples were taken from 60 patients, then stored at room temperature. DNA extraction was carried out at distinct post-sampling times (10, 20 and 30 days). Evaluation of genomic DNA was performed with spectrophotometry, electrophoresis, and PCR genotyping and sequencing.
Background: Association between periodontal disease (PD) and chronic obstructive pulmonary disease (COPD) has been widely studied and the aspiration of periodontal pathogens is one of the most accepted causal mechanisms for pulmonary exacerbation. Bronchiectasis is clinically quite similar with COPD, including chronic administration of antibiotics, increased systemic inflammation and relatively similar clinical symptoms, but for the time being; there are no studies that have correlated this condition to PD. This study will evaluate if the scaling and root planning (SRP) associated with photodynamic therapy improves periodontal clinical parameters, halitosis, and the quantity of microorganisms associated with exacerbation of bronchiectasis in saliva, subgingival periodontal microenvironment, sputum and nasal lavage at baseline, after 3 months and one year of SRP. Methods/Design: Ninety patients with chronic periodontal disease and bronchiectasis will be enrolled in the study and they will be treated as follow:G1 control (n = 30) - supragingival scaling (SS) and dental hygiene orientation (DHO); G2 experimental (n = 30) - SRP + DHO; G3- experimental (n = 30) - SRP + PDT + DHO. The quantification of bacterial groups commonly associated with exacerbation of bronchiectasis (P aeruginosa, S. aureus) and periodontal diseases (P. gingivalis), will be evaluated in periodontal pockets, saliva, nasal lavage and sputum by quantitative PCR at baseline 3 months and one year after the SRP. G1 patients will receive SRP upon completion of the investigation. If the mean depth of probing of this group worsen (> 1mm) at 3 months they will be excluded from the study, treated (SRP) and the data will be described. Discussion: The results of this protocol will determine the efficacy of periodontal treatment in decreasing the total amount microorganisms in saliva periodontal pocket, sputum and nasal lavage, the most probable niches of bronchiectasis exacerbation, and reducing local inflammation and halitosis after 3 months and one year. It is expected an higher improvement in all parameters measured over 3 months and 1 year for G3
Obesity is an epidemic with increasing prevalence in the Asia Pacific region. The first Malaysian national estimate in 1996 of obesity was 5.8%. A systematic review reported a marked increase in obesity in 2003, 2004 and 2006 with 12.2%, 12.3% and 14.0% respectively. Periodontal disease is a chronic inflammatory disease which results in gingival inflammation, irreversible attachment loss, alveolar bone destruction and eventually tooth loss. Worldwide, the prevalence of periodontitis in the adult population is about 10-15%. Periodontal disease, through inflammation and destruction of the periodontium produces clinical signs and symptoms, some of which may have a considerable impact on quality of life (QoL). A positive association between obesity and periodontal disease was repeatedly demonstrated worldwide. Obese individuals have elevated levels of circulating TNF- α and IL-6 compared to normal weight individuals. These cytokines decrease after weight loss. Adipokines produced by adipose tissue could be one of the mechanisms mediating the association between obesity and periodontal disease. This suggests that obesity may have the potential to modify the host's immunity and inflammatory system. This project will extend the existing information on the association between obesity and periodontal disease including QoL aspect to a Malaysia population. It will also improve knowledge on the cellular and molecular mechanisms that underpin obesity-periodontal disease relationship. By extension, this study also will cast light on the effects of periodontal interventions for the subgroup population.
The purpose of the study is to evaluate if surgical treatment of peri-implantitis with enamel matrix derivative (Emdogain®, EMD) will have an additional effect on the healing outcome, changes in the peri-implant microflora and on the inflammatory response in the periimplant pocket at 12 months.
The aim of this clinical study is to asses the effect of ultrasonic periodontal debridement associated to locally delivered doxycycline (20%) by PLGA microspheres on chronic generalized periodontitis treatment.
To clinically evaluate the treatment of mandibular class II furcation defects with enamel matrix derivative (EMD) and/or a bone substitute graft make of beta tricalcium phosphate/hydroxyapatite (βTCP/HA).
Till date, no study has been reported in the literature where porous bioactive glass was used for the management of periodontal osseous defects. In this context, the present study is designed to assess the efficacy of the porous variant of bioactive glass and compare with that of nonporous variant using cone beam computed tomography.
This study aim is to determine the efficacy of two Oral Hygiene Regimens in the reduction of dentin hypersensitivity on subjects undergoing non-surgical periodontal treatment, over a period of 8 weeks.
This study has compared quadrant scaling and root planing (Q-SRP) versus intensive treatment performed within 24 hours (FM-SRP) in terms of acute phase responses following treatment of periodontal disease. The primary aim was to compare the differences in CRP acute increase following FM-SRP versus Q-SRP therapy (24 hours after therapy). Secondary outcomes included changes in a broad array of inflammatory and endothelial injury markers between groups. Patients were randomly assigned to either FM-SRP and Q-SRP. Data indicated that non-surgical periodontal therapy performed within 24 hours induced greater perturbations of systemic inflammation compared to conventional treatment.
The purpose of this study was to evaluate acute phase proteins (APPs) Fetuin-A and Serum Amyloid A (SAA) levels in gingival crevicular fluid (GCF) and serum samples in periodontal health and disease.
