Research summary
Background: Diabetes mellitus (DM) is well-known for long-term complications to general and oral health. Periodontal disease has a bidirectional association with the development of type 2 diabetes (T2DM) (Mealey, 2006; Taylor, 2001; Demmer et el.,2008). However, current literature conflicts with regards to dental caries incidence in patients with T2DM (Sampaio, Mello and Alves, 2011).
Objective: To investigate potential protective and risk factors for dental caries among T2DM with vitamin D and HbA1c using clinical, salivary and microbial analyses.
Methods: This project is a case-control clinical study. The study will be conducted at Royal London Dental Hospital, Institute of Dentistry, Bart’s Health NHS Trust, London, UK. This study will aim to recruit 182 participants in total with diabetes (type 2), aged ≥18 male or female and participants will be cross-matched with non-diabetes according to age and gender.
Each participant will undergo an assessment for around 60 minutes where all the following assessments will be carried out; Caries risk assessment (CAMBRA), Plaque index, International Caries Detection and Assessment System (ICDAS) and Laser fluorescence evaluator (SOPRLIFE®, Acteon, France) and Oral behavioural and sociodemographic background will be collected. In addition, blood, saliva and supragingival plaque samples will be collected for later metabolome and microbial investigation.
Prior to the clinical study, there will be a laboratory-based study using extracted teeth with dental caries. The aim of this ex-vivo study is to assess the autofluorescence variations on dental carious lesions and compare this with International Caries Detection and Assessment System (ICDAS).
Results Summary
This research investigated whether individuals with Type 2 Diabetes Mellitus (T2DM) are at higher risk of dental caries (tooth decay) compared to people without diabetes. The study involved 182 adult participants and examined their oral health, blood and saliva biomarkers (including HbA1c and vitamin D), oral hygiene habits.REC name
