Filter by:To assess the demographic variables, periodontal parameters and to determine the expression of Trefoil factors 2 and 3 and Adrenomedullin in unstimulated saliva samples of periodontally healthy subjects with coronary heart disease and generalised chronic periodontitis subjects with and without coronary heart disease.
Three techniques for periodontal reconstruction will be compared, in which marginal access versus apical access will be carried out.
The Hamburg City Health Study (HCHS) is a large, prospective, long-term, population-based cohort study and a unique research platform and network to obtain substantial knowledge about several risk and prognostic factors in major chronic diseases.
This study evaluates clinical and radiographic parameters among riks factor groups in patients with periimplantitis. This study will also treat and evaluate the patients response before and after surgical treatment.
Pregnancy is a physiological state that is part of the reproductive life of women, establishing their fertile age between 15 and 45 years mainly. This stage will not only mark the birth of the baby but also cause various changes both immunological and physiological, to accommodate the growing fetus. Maternal periodontitis has direct and indirect potential to influence the health of the fetus-maternal unit. According to the literature reviewed, the first evidence that oral bacteria influenced pregnancy outcomes was reported by Collins et al. The injection of P. gingivalis into pregnant hamsters caused intrauterine growth retardation and smaller fetuses, together with an increase in the levels of proinflammatory mediators (IL-1b and PGE2) in the amniotic fluid. Two hypotheses have been pointed out regarding the link between oral health and the adverse outcome of pregnancy. The first states that periodontal disease causes abnormal systemic immune changes, leading to complications in pregnancy. While the second hypothesis suggests that oral bacteria directly colonize the placenta, causing localized inflammatory responses, resulting in prematurity and other adverse outcomes.
The quantification of CD163 will be analysed in the subgingival plaque samples of generalized chronic periodontitis patients with and without diabetes mellitus. The demographic and the periodontal parameters were assessed and the correlated with the quantification of the CD163. The CD163 gene expression was analyzed with RT-PCR and the quantification of CD163 will be done using ELISA.
Background Post-radiotherapy head and neck cancer (HANC) patients are at increased risk of dental caries and periodontal disease due to radiation-related damage to the teeth and salivary glands. Currently the exact aetiology of post-radiotherapy dental disease, and variation in its incidence and severity based on tumour location and radiotherapy dose, is poorly understood. Consequently there is a lack of clear guidance on how HANC patients should be dentally managed both before and after their radiotherapy. Aim The aim of this study is to quantify the relationship between dental radiation dose, 'spared' parotid gland radiation dose, tumour location, and post-radiotherapy dental disease. Methods A prospective cohort study will be undertaken in HANC patients treated with radiotherapy. A total of 215 patients will be recruited over a period of 2.5 years. Participants will be assessed and rendered dentally fit prior to radiotherapy in the School of Dentistry, Belfast. All patients will be followed-up at 6, 12, and 24-months post-radiotherapy. Data to be collected at each visit will include: total number of carious teeth, periodontal disease indices, salivary flow rates, diet, oral hygiene, mouth opening, xerostomia and oral health-related quality of life. Radiotherapy, including individual tissue-dose exposures, will be prescribed by the Clinical Oncology team as per current practice. Doses to the teeth and 'spared' parotid gland will be determined using radiotherapy research software (Non-Clinical Eclipse System sold by Varian Medical Systems UK Ltd). Using appropriate statistical tests, data analysis will determine the relationship between dental disease, radiation dose, and tumour location. Anticipated variation in the incidence and severity of post-radiotherapy dental disease based on the radiotherapy dose and tumour location, will inform the development of a clinical risk-assessment tool that will allow dentists to categorise patients as 'high' or 'low' risk of future disease. Guidelines regarding pre-radiotherapy dental extractions and post-radiotherapy preventative strategies will also be developed and will advise clinicians based on this risk assessment. A micro-costings study will be undertaken to evaluate patient and healthcare costs associated with the diagnosis and management of pre- and post-radiotherapy dental disease.
The primary objective of the study is to assess the incidence and severity of the periodontal infection of patients with preterm labor. The secondary objective of the study is to analyze the relationship between preterm labor and periodontal infection, using clinical, biochemical and microbiological methods.
The primary objective of the study is to assess the incidence and severity of the periodontal infection of patients with preeclampsia. The secondary objective of the study is to analyze the relationship between preeclampsia and periodontal infection, using clinical, biochemical and microbiological methods.
The aim of this study was to investigate the mechanism of indocyanine green photodynamic therapy (PDT) in periodontal therapy. The investigators will recruit 80 participants receiving conventional periodontal disease treatment, or can not fully accept the regular periodontal treatment of adult periodontal disease, photodynamic therapy, and oral periodontal disease of the teeth as the control group, before treatment , Gingival crevicular fluid and dental plaque were collected at 6 weeks, and 6 months after the treatment. The biochemical indexes and strains were analyzed and the data of the participants Term periodontal index. In this study, indocyanine photodynamic therapy can improve the discomfort of patients with periodontal disease and the periodontal index, the treatment area of the bacteria and the inflammatory response will be significantly decreased, and look forward to this study can establish the indigo cyanine light dynamic teeth Week therapies to provide periodontal patients with more comfortable and effective clinical therapy.
