Impact of Periodontal Therapy on Patients With Diabetes

Impact of Periodontal Therapy on Patients With Diabetes: A Pilot Study

• Status: Completed
• Phase: Phase 2

• Sex: All
• Age: 25 Years
• Healthy volunteers: Not accepted

Summary

With poorly controlled diabetes, periodontal status often worsens, and with severe periodontal conditions there is often poorer glycemic control. There are few published reports investigating the efficacy of periodontal therapy in diabetics and fewer that include evaluation of the oral microbial profiles (the microbiome). The investigators will examine systemic changes in diabetes status and microbiome influences on clinical response to periodontal therapy in a randomized clinical trial of participants with and without diabetes and with periodontal disease. Two different treatments will be used: 1. Scaling and root planning (SRP) alone, or 2. SRP and supportive periodontal therapy (SPT), the use of chlorhexidine gluconate rinse (Paroex®) and a rubber interdental bristle cleaner (Soft-Picks) The main goal of this clinical trial is to evaluate the effects of SRP alone versus SRP+SPT on clinical, microbiological and immunological status in participants. A clearer understanding of how periodontal therapy affects diabetes status could lead to the development of new therapies for periodontal disease and diabetes.

Detailed description

With poorly controlled diabetes, periodontal disease worsens, and with severe periodontal conditions, there is often poorer glycemic control. Published papers conclude that periodontal treatment leads to a reduction in hemoglobin A1c; however, other studies show limited or no improvement. Some patients do not respond well to professional periodontal therapy, even without diabetes, which could be related to poor oral hygiene and/or host factors including microbial profiles. There are few published papers investigating the efficacy of periodontal therapy in diabetics and fewer that include assessment of the oral microbiome. The investigators will examine systemic changes in diabetes status and microbiome influences on clinical response to periodontal therapy in a randomized clinical trial. It has been shown that chlorhexidine gluconate rinse leads to significant clinical improvement over standard periodontal therapy alone, and interdental tooth cleaners remove more dental plaque (leading to reduced gingival inflammation) effectively than brushing alone. Therefore, in this study, standard periodontal therapy, scaling and root planning (SRP) will be provided alone, or SRP plus supportive periodontal therapy (SPT), the use of chlorhexidine gluconate rinse (Paroex®) and a rubber interdental bristle cleaner (Soft-Picks), to diabetics and non-diabetics with periodontal disease to determine the differences in response between the groups. The main aim of this study is to evaluate the effects of SRP alone versus SRP+SPT on clinical, microbiological and immunological status of subjects with and without type 2 diabetes and with periodontal disease. A clearer understanding of how periodontal therapy affects diabetes status could lead to the development of novel new targeted therapies of both periodontal disease and diabetes.

Conditions

• Diabetes Mellitus, Type II
• Periodontitis

Interventions

Type	Name	Description
DRUG	Chlorhexidine gluconate oral rinse	Paroex® is a non-alcohol chlorhexidine preparation. Participants are to use 15 mL morning and evening for 3 months. With use of chlorhexidine, there is risk of reversible staining of teeth and the possibility of some alteration in taste. There is increased likeliness of staining in smokers, coffee drinkers and those who are susceptible to teeth staining in general. The cleaning of the front teeth is provided at the 3-month visit and helps to reduce any staining that may occur. If there is any alteration in taste, it should go away when use of chlorhexidine stops.
PROCEDURE	Scaling & Root Planing	SRP is standard treatment of periodontitis. It involves using a scaler to remover subgingival plaque and other debris in the space between teeth and gums.
DEVICE	Soft Picks	Soft Picks are a rubber interdental bristle cleaner. Participants are to use Soft Picks morning and evening for all 12 months of the study. They may cause some bleeding of the gums at first usage, but the bleeding should lessen and stop as use is continued (as gums heal). Soft-Picks are a readily available consumer product sold in supermarkets and drug stores.
