Flavonoid Intake and Periodontal Healing

January 13, 2019 updated by: Wendy E. Ward, Ph.D., Brock University

Flavonoid Intake and Periodontal Outcomes After Sanative Therapy

Periodontitis is a chronic inflammatory disease that, if untreated, will lead to tooth loss. To treat periodontal disease, sanative therapy is used as a first line cost-effective strategy to manage periodontal disease and thus prevent tooth loss. Diet is emerging as a modifiable factor that may help an individual to more fully respond to treatments such as sanative therapy. Dietary flavonoids, abundant in fruits and tea, may be particularly beneficial. Patients with moderate to severe chronic generalized periodontitis and undergoing sanative therapy will be recruited for the study. Mean clinical attachment loss as well as other clinical measures will be assessed at baseline and 8 to 12 weeks following sanative therapy to measure periodontal healing. At baseline and follow-up appointment, the following will be assessed to examine associations with clinical measures of periodontal healing: intakes of macronutrients and micronutrients, fruits, vegetables and tea as well as supplement use and salivary markers of inflammation.

Detailed Description

Periodontitis is a chronic oral infection that results in the breakdown of connective tissue and alveolar bone that support the teeth. Bacteria and the body's own immune system mediate the severity of periodontitis, where teeth may become loose, fall out or have to be removed. Sanative therapy is a non-surgical process invovling mechanical debridement of bacterial biofilms on roots of teeth, below the gum line. A previous study found that a diet higher in fruits and vegetables, beta-carotene, vitamin C, alpha-tocopherol, and fish oils (specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) was positively associated with periodontal healing after sanative therapy. There is some evidence that higher intakes of flavonoids and thus flavonoid-containing foods may benefit periodontal health. These foods include a wide variety of fruits and tea. The relationship of flavonoid intake within the overall dietary pattern has not been assessed in relation to recovery from sanative therapy and associated markers of improved periodontal health. The overall objective is to determine if higher dietary flavonoid intakes are associated with improved clinical outcomes after sanative therapy compared to individuals with lower intakes. At baseline and the follow-up appointment, the following will be assessed: dietary intakes of macronutrients and micronutrients using the Block 2015 food frequency questionnaire; intakes of fruit, vegetables and fiber using the Block Dietary Fruit-Vegetable-Fiber Screener; nutritional supplement use and tea intake using in specially developed questionnaires and salivary markers of inflammation.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Patients undergoing sanative therapy for the treatment of moderate to severe chronic generalized periodontitis.

Description

Inclusion Criteria:

  • Adult patients undergoing sanative therapy for moderate to severe chronic generalized periodontitis. Chronic periodontitis is classified as generalized if >30% of sites are involved. Severity of periodontitis is based on the amount of clinical attachment loss (CAL) with moderate and severe chronic generalized periodontitis defined as 3 to 4 mm CAL or > 5 mm CAL, respectively.

Exclusion Criteria:

  • under 19 years of age

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Clinical Attachment Loss (CAL) (also called Periodontal Attachment Loss)
Time Frame: At baseline and at follow-up (8 to 12 weeks after completion of sanative therapy)
Periodontal healing is evaluated based on changes in clinical attachment loss (mm)
At baseline and at follow-up (8 to 12 weeks after completion of sanative therapy)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Probing Depth
Time Frame: At baseline and at follow-up (8 to 12 weeks after completion of sanative therapy)
Periodontal healing is evaluated based on changes in probing depth (mm)
At baseline and at follow-up (8 to 12 weeks after completion of sanative therapy)
Bleeding on Probing
Time Frame: At baseline and at follow-up (8 to 12 weeks after completion of sanative therapy)
Inflammation is determined by percent of bleeding sites that are measured at 6 sites per tooth
At baseline and at follow-up (8 to 12 weeks after completion of sanative therapy)
Plaque Index
Time Frame: At baseline and at follow-up (8 to 12 weeks after completion of sanative therapy)
O'Leary Plaque Score Index is a score of the total amount of plaque present at 4 surfaces of a tooth

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
