There a multiple appointments throughout the study which can vary depending upon if a patient has the disease present or not.
If the patient has gum disease: At the initial examination, some samples will be collected: the natural fluid that comes from the gums and the bacteria that are present there will be collected by inserting a piece of paper and a filter strip in the spaces between teeth and gums; blood samples may also be taken by a phlebotomist to evaluate some inflammatory signs of disease and possible genetic markers (about 5 teaspoons at each visit); and a cheek swab may be taken by gently rubbing a little brush into the inside of the cheeks. Patients also may be asked to spit into a container we provide. Tissues from gums that are usually discarded may also be collected during treatment. When patients return for re-evaluation of their gums, all these samples may be collected again at 3, 6, 12, 18 and 24 months after the initial therapy. After 24 months, only clinical examinations may be performed, up to 3 more visits within the following 3 years.
If the patient does not have gum disease: If gums are healthy and the patient does not need treatment, they will be seen every 6 months for examination and cleanings, then sample collections may also be taken at these visits up to 24 months. These sample collections are done to be studied by genetic tests, which will tell us if there are specific genetic markers (inherited markers) associated with this disease, and also other laboratory testing, which will help the researchers identify how the body responds to bacteria. These markers will also be evaluated in family members (parents, grandparents or siblings), when possible, to check for the likelihood of these members developing this disease.
Regardless of the patient's gum condition, investigators will also evaluate current and past dental x-rays to determine if there were signs of this disease in the past.
Investigators may also take photos of the teeth and gums.

Experimental: Diseased periodontal treatment
Scaling and root planing along with systemic antibiotics (Amoxicillin 500 mg and Metronidazole 250 mg tid 7 days).
Procedure: Diseased periodontal treatment
Treatment includes scaling and root planing with systemic antibiotics, Amoxicillin 500 mg and Metronidazole 250 mg tid 7 days. At certain intervals after the scaling and root planing, your gums will be reevaluated. You will receive further surgical gum therapy only if your gums haven't shown improvement after first treatment on the reevaluation appointments. If surgery is needed, a bone substituting material may be necessary to "fill" the spaces where bone has been destroyed by the disease. Extraction of teeth might also be part of gum treatment if the disease is very severe. Re-treatment with antibiotics also may be necessary depending on the response after treatment. You are usually re-examined and receive additional cleanings every 3 to 6 months to ensure the disease does not come back.
Active Comparator: Conventional periodontal treatment
Standard periodontal prophylaxis
Procedure: Conventional periodontal treatment
Scaling and gum measurement will be taken to compare to the treated group.- If it is determined that you do not have this disease, a conventional cleaning is done, usually every 6 months. This is all part of normal clinical care.
- SNPs and DNA methylation [ Time Frame: 24 months ]The investigators are doing analysis of single nucleotide polymorphisms (DNA sequence variation) and methylation (addition of a methyl group) of DNA of specific genes related to inflammation.
- Systemic inflammatory levels [ Time Frame: 24 months ]The investigators are testing for systemic (plasma levels) and local (gingival fluid levels) markers of inflammation.
