OBJECTIVE: The current study aims to reconnoiter the outcome of diabetes mellitus type 2 (DMT2) on levels of advanced glycation end products (AGEs) and pro-inflammatory chemokine in gingival crevicular fluid (GCF) of individuals undergoing fixed orthodontic treatment.

PATIENTS AND METHODS: Participants were divided into a diabetic and no-diabetic group according to inclusion and exclusion criteria. Power analysis was adopted from a previous study that reported GCF chemokines in obese individuals. All teeth were measured for clinical periodontal parameters (CPP). GCF and saliva were collected 3 months after placing stainless steel archwire. GCF was investigated for pro-inflammatory cytokines all expressed in pg/mL. Quantification of chemokines was performed using a Magnetic bead-based multiplex assay for the Luminex® platform. Non-normality of data was assessed by Mann-Whitney U-test. Normality was estimated using an Independent t-test. Descriptive data were computed in the form of standard deviations and means.

RESULTS: Unstimulated whole saliva flow rate (UWSFR) was significantly lower in diabetic patients compared to non-diabetics (p=.021). Amongst different clinical periodontal parameters (CPP) no difference in plaque scores (PS) and probing depth (PD) was found between diabetic and non-diabetic participants. Two GCF chemokines i.e., Resistin (p=.031) and AGEs (p=.017) were observed to be significantly higher in DMT2 participants compared to the non-diabetes group. CPP and GCF biomarkers in diabetic and non-diabetic individuals demonstrated a positive correlation between AGEs and GCF resistin levels concerning bleeding on probing (BoP) in diabetic patients.

CONCLUSIONS: Participants with DMT2 after alignment with an orthodontic device exhibited significantly high levels of resistin and AGEs. The proinflammatory response was noted in patients with hyperglycemia undergoing orthodontic treatment.
