Research purpose: The research question is individuals with Diabetes Mellitus type 2 (T2DM) is more prone to dental caries?

Research purpose: The research question is individuals with Diabetes Mellitus type 2 (T2DM) is more prone to dental caries? Several literature reviews point the lack of solid evidence clear association of the DM and dental caries (Ship, J.A., 2003; Taylor et al., 2004; Lamster, I.B., 2014; Garton et al., 2012; Leite et al., 2013).Also, a controversial result available of the epidemiology of dental caries among individuals with T2DM (Sampaio, Mello and Alves, 2011), besides limited knowledge about the biological explanation as seen with periodontal disease (Verhulst et al., 2019).Moreover, no study had a comprehensive evaluating of all potential caries risk factors. Thus this study developed a preliminary conceptual model in which 48 potential risk factors were identified and categorised into four domains: biological/intra-oral factors, medical factors, oral health behaviour, and sociodemographic factors. All these potential factors will be evaluated and analysed through different appoaches; clinical, salivary, microbial analyses and patient questionnaire. Recruitment process: All participants (n=182) who meet the selection criteria and agree to participate will be invited to complete written informed consent by the PI. Invitation letters will be sent by the DARE database holders to Diabetes patients who are on this database. Diabetes patients from Royal London Dental Hospital including outreach centres (Barkantine, Southend and Guttman), General Endocrinology and Metabolic Medicine, Diabetic clinics (including Mile End hospital) will also be invited using another invitation letter. Regarding the control group, adult patients attending Dental Institute including outreach centres (Barkantine, Southend and Guttman), staff within Queen Mary University of London and Barts Health Trust and volunteers who agree to participate will be recruited. All these participants will be approached and asked by the PI/CI whether they would be interested in taking part in this research. Participants who meet the inclusion criteria, will receive a written Patient Information Sheet (PIS) describing the study in details (Appendix 3). Subsequently, they will be asked by the Principal Investigator (AA) to complete and sign written informed consent (Appendix 4), if they wish to take part in this study. This phase will take around 15 minutes. Those who consent to take part will be given an appointment to attend the dental clinic for assessments at the Institute of Dentistry. Participants may enter the trial if the following apply: Participants who are male or female ? 18 years of age. For the test group, they have been diagnosed with type 2 Diabetes For the control group, participants who are not diagnosed with type 2 Diabetes Particiapants having minimum one natural tooth They are capable of giving informed consent They have the ability to understand and speak English They are able and willing to comply with all trial requirements They are not participating in another dental trial They are not diagnosed for cognitive defect due to mental illness, depression, Alzheimer's disease, or dementia. No antibiotic, no steroidal and/or non-steroidal anti-inflammatory medication used during the last 3 weeks Participants who are not pregnant and also not breastfeeding Participations who are not in another dental study testing different dental products during the previous three months and during the study period Participants who are not currently taking Vitamin D supplements Exclusion criteria Participants who are edentulous Cognitive defect due to mental illness, depression, Alzheimer's disease, or dementia. The presence of any hard or soft tissue tumours in the oral cavity Patients undergoing chemo and/or radiation therapy Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial. Any condition, which in the opinion of the investigator, would preclude participation by the subject (such as cross-infection control risk) Participants who are prescribed long-term systematic antibiotics Participants who are pregnant and breastfeeding Participations who are in another dental study testing different dental products during the previous three months and during the study period Participants who had additional fluoride treatment in the past 6/3 months Participants who are prescribed to use high fluoridated toothpaste Participants who are currently taking Vitamin D supplements Consent: The potentially capable participant will be asked to confirm that they: Read and understand the information sheet for the study. Had the opportunity to consider the information, ask questions and have had these answered satisfactorily. Understand that his participation is voluntary and that he is free to withdraw at any time without giving any reason, without his medical care or legal rights being affected. Understand that relevant sections of his dental notes may be looked at by responsible individuals from regulatory authorities where it is relevant to his taking part in this research and give permission for these individuals to have access to his records. Agree to take part in this study. Participants would have the opportunity to withdraw consent at any time and to ask for their samples to be destroyed or the data excluded from research Risk, burden, and benefits: Those patients who consent to participate will undergo a routine dental examination to detect the dental caries extent by the aid of dental examination kit and fluorescence image evaluator device and they will be expected to collect a sample of supragingival plaque, saliva and blood. This study is observational study without any intervention so no harm expected for these participants There may be some benefit to the participant, since they will receive full mouth examination and cleaning if required in addition to the blood test for HbAc and vitamin D level. Confidentiality: Confidentiality will be observed in relation to the Caldicott Principles. Only the CI and PI will have access to this information which will be coded and secured safely by password protection and encryption. Conflict of interest: There are no known conflict of interest.
