Obesity Clinical Trial
Official title:
Periodontal Assessment of a Bariatric Care Population, Clinical, Genetic and Microbiological Characteristics. A Cross-sectional Study.
Our primary aim is to investigate the prevalence and severity of Periodonotal Disease (PD) in a population of obese patients. Our secondary objectives are to: Investigate inflammatory biomarkers that have been associated with PD in the saliva of obese patients. Investigate the association of FTO gene (Obesity) polymorphisms with the prevalence of PD in this population. Investigate and describe the subgingival microbial flora in obese patients with PD from subgingival dental plaque samples as well as the salivary samples.
Overall design and plan of the study This is a cross-sectional association study. The study population will be recruited among individuals attending the UCLH Centre for Weight Loss, Metabolic & Endocrine Surgery (UCLH bariatric clinic) and have given written informed consent to the study. Experimental Design All individuals who consent to this study will receive as part of their routine care a medical examination, where a series of parameters are recorded (including age, gender, smoking status, Bio-impedance for full body composition, ethnicity, and body mass index). These data will be copied for this study. A blood sample will also be collected for genetic analysis unless the patients have DNA already collected and it has been verified that the results are available. In that case no venepuncture will be needed. All subjects will receive a basic periodontal examination (BPE). For individuals with signs of destructive periodontitis (BPE scores 3-4) full mouth plaque and gingival bleeding scores will also be calculated. In addition to that also a comprehensive full mouth periodontal probing depths assessment will be performed. ;
