Are Diabetics Type 2 More Prone to Dental Caries?

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 a baseline screening 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. Prior to the clinical study, there will be a laboratory based study using extracted teeth. The aim of this ex-vivo study is to assess the autofluorescence variation in dental carious lesions and compare this with International Caries Detection and Assessment System (ICDAS).

Orthodontic Varnish Microbiology Study

Orthodontic treatment is common in teenagers, which typically involve the attachment of metal brackets to the teeth. These brackets often impede proper oral hygiene, leading to plaque accumulation and the development of white spots lesions (the early stage of cavity development). Our study aims to investigate the efficacy of different commercially available fluoride varnishes to treat these white spot lesions after the completion of orthodontic treatment and evaluate their effect on the oral microbiome. Target enrollment is 120 subjects. The study will follow a split-mouth design, with each subject receiving different treatment on the left and right sides of their mouth. The subjects will be randomized into 3 groups, with each group receiving two of the following three options: placebo varnish, traditional sodium fluoride varnish, and a resin-modified glass ionomer light-cured fluoride varnish. There will be 4 total visits for this study: Baseline (day 0): Oral health assessed, plaque collected, intraoral photos taken, dental cleaning performed, DiagnoDent measurements taken, varnishes applied T1 (day 30): Oral health assessed, plaque collected, intraoral photos taken, DiagnoDent measurements taken, varnishes reapplied T2 (day 90): Oral health assessed, plaque collected, intraoral photos taken, DiagnoDent measurements taken, varnishes reapplied T3 (day 180): Oral health assessed, plaque collected, intraoral photos taken, DiagnoDent measurements taken, dental cleaning performed Participants will be instructed to use regular fluoridated toothpaste and floss twice per day for the duration of the study.
