Periodontal Treatment Response in Type II Diabetic Patients

The Influence of Periodontal Treatment on Gingival Inflammatory Response of the Type II Diabetic Patient

Diabetes mellitus affects > 171 million people worldwide, with type II diabetes being the most prevalent, affecting 85-95% of the diabetic population. Unfortunately, despite conventional medical treatment, some diabetic patients do not seem to be able to reach desirable metabolic control. This is a double-blinded, randomized study investigating the effects of triclosan containing toothpaste (commercial name: Colgate Total) on the response to periodontal treatment in type II diabetic patients with periodontal disease. The investigators believe that using triclosan containing toothpaste during periodontal treatment will decrease the local inflammatory response and that this reduction will improve periodontal status and metabolic control.

Study Overview

• Status: Completed
• Conditions: Periodontal Disease; Type II Diabetes
• Intervention / Treatment: Drug: Triclosan containing toothpaste; Drug: Non-triclosan containing toothpaste

Detailed Description

Many studies have shown a relationship between chronic inflammatory periodontal diseases and diabetes, in which both diseases influence the other. Research studies have shown that controlling inflammation of the gums can improve the level of metabolic control (i.e. blood glucose levels) in patients with diabetes. However, it is still not clear which periodontal treatment approach would best maintain the control of inflammation of diabetic patients. Triclosan has anti-plaque and anti-inflammatory properties and decreases gum inflammation. The purpose of this study is to 1) determine the effects of triclosan containing toothpaste on gum inflammation in type II diabetic patients with periodontal disease, and 2) to evaluate whether type II diabetic patients will show improvement in periodontal status and blood glucose following periodontal treatment with and without the use of a triclosan containing toothpaste.

Patients with type II diabetes that meet the study criteria will be randomly assigned either triclosan containing toothpaste or placebo toothpaste. Dental cleanings and oral exams will be performed at baseline, 6 weeks, 3, 6, 9 and 12 months, and samples will be collected at baseline, 3, 6 and 12 months. Samples that may be collected include blood, plaque, gingival crevicular fluid, saliva and plaque. Women may also be asked to complete a pregnancy test. Photographs and x-rays of the patients mouth/teeth may be taken, but is not a requirement.

The samples collected will be used to assess the effect of triclosan containing toothpaste on glycemic control and local and systemic inflammatory mediators during the course of periodontal treatment.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Triclosan containing toothpaste; Patients with type II diabetes will receive triclosan containing toothpaste and will be asked to brush their teeth using only this toothpaste for the duration of the study (12 months). Patients will be asked to return for an oral exam, dental cleaning and sample collection for up to 12 months following their baseline appointment.	Drug: Triclosan containing toothpaste; Type II diabetic patients will be instructed to brush their teeth at the same time day and with the same frequency as usual for them using only the triclosan containing toothpaste provided to them. Additional tubes of triclosan containing toothpaste will be provided to the participants for the duration of the study as needed. Following their baseline appointment, patients will be asked to return at 6 weeks, 3, 6, 9 and 12 months for an oral exam and dental cleaning. Samples will be collected at baseline, 3, 6 and 12 months. Samples collected may include venous blood, gingival crevicular fluid, plaque and saliva. Female study participants may be asked to perform a pregnancy test.; Other Names: Colgate Total

Drug: Non-triclosan containing toothpaste; Type II diabetic patients will be instructed to brush their teeth at the same time day and with the same frequency as usual for them using only the non-triclosan containing toothpaste (i.e. placebo) provided to them.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame

Clinical parameters will be assessed using a conventional periodontal probe and recorded in supporting software (Florida Probe).	Baseline, 3, 6 and 12 months
Local Inflammatory Markers	The changes in local inflammatory markers (i.e. cytokines, chemokines, metalloproteinases) during periodontal treatment from baseline to 3 months, 6 months and 12 months. Local inflammatory markers in gingival crevicular fluid will be assayed in the laboratory.	Baseline, 3, 6 and 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame

Blood will be analyzed by the core lab facility at the University of Florida and Shands hospital and in the clinic/laboratory using a commercially available finger prick device and testing strips.	Baseline, 3, 6 and 12 months
Systemic Inflammatory Markers	The changes in systemic inflammatory markers (i.e. cytokines, chemokines, metalloproteinases) during periodontal treatment from baseline to 3 months, 6 months and 12 months of periodontal treatment. Inflammatory markers in venous blood will be assayed in the laboratory.	Baseline, 3, 6 and 12 months
