Brief summary
The aim of this study is to investigate the effectiveness of daily supplementation with inulin before, during and after sanative therapy (ST), on clinical outcomes of periodontal disease. The study design will allow the investigators to conclude if supplementation with inulin can favourably modulate oral microbiota prior to ST and can result in better periodontal health after ST.
Detailed description
Periodontal disease is a chronic state of inflammation that can destroy the supporting tissues around the teeth, leading to a loss of connective tissue and the periodontal ligament, the resorption of alveolar bone and eventual tooth loss. Periodontal disease can also induce dysbiosis in the gut microbiome and contribute to low grade systemic inflammation. Prebiotic fibres such as inulin can selectively alter the intestinal microbiota to bring back a state of homeostasis by improving gut barrier functions and preventing inflammation. Through this mechanism, supplementation with inulin may be able to indirectly benefit periodontal health. The primary objective of this trial to determine if inulin supplementation, provided pre-sanative therapy (ST) through the healing phase (post-ST) is more effective than the placebo at improving clinical outcomes of periodontal health: decreasing both the number of sites with probing depths greater than or equal to 4 mm and increasing the absence of bleeding on probing (BOP). Secondary objectives include determining the effects of inulin supplementation pre- and post-ST on salivary markers of inflammation and periodontal-associated pathogens.

Masking
DOUBLE (Subject, Caregiver)
Masking description
The intervention packages will be labelled with a unique code and there will be enough packages to account for the required number of participants. A member of the research team, not involved in providing the treatment, will be responsible for the randomization and labeling of the intervention packages, as well as creating a master list by matching the unique code to the treatment arm. The patient and care provider will be masked to the treatment arm.
Intervention model description
Subjects will be randomized to receive one of the two treatments. They will be required to take one sachet per day (half in the morning; half in the evening) of the assigned intervention beginning 4 weeks before their scheduled sanative therapy appointment and remain on the intervention until 10 weeks after their sanative therapy appointment.

Inclusion criteria
* Both males and females age 19 years or older who are undergoing sanative therapy for moderate to severe chronic periodontitis are eligible * Provided informed, written consent
Exclusion criteria
* Patients with severe periodontal disease that requires antibiotics with ST as part of their treatment * Hemoglobin A1c levels greater than 8% in the previous 3 months * Chronic GI conditions and/or infections (e.g. colon cancer, crohn's disease, inflammatory bowel disease, celiac disease and ulcerative colitis) * Current or previous use of antibiotics for management of non-periodontal conditions within the past 3 month * Current use of laxatives, prebiotics, probiotics and/or fibre supplements * Smokers and/or cannabis users * Pregnant or breast-feeding
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Probing depth | At pre-sanative therapy | This is a routine clinical measure of periodontal health (measured in mm) |
| Bleeding on probing (BOP) | At pre-sanative therapy | This is a clinical measure of inflammation and represented as the percentage to bleeding sites that are measured at 6 sites per tooth |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Salivary markers of inflammation | At pre-sanative therapy | Levels of interleukin (IL)-1beta, IL-6, C-reactive protein (CRP), Matrix metalloproteinase-8 will be measured. |
| Periodontal-Associated Pathogens | At pre-sanative therapy | Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola will be measured by quantitative polymerase chain reaction (PCR). |
| Dietary assessment | At pre-sanative therapy | Intake of energy, carbohydrate, fat and protein will be measured with the automated self-administered dietary intake (ASA-24) questionnaire. This is an online food recall that patients will complete three times for each visit, reporting on their dietary intake from the last 24 hours. |
| Body Mass Index | At pre-sanative therapy | Body weight and height will be measured to calculate BMI |
