the effect Hyaluronic Acid in the Treatment of Furcation Involvement

The materials to be used in the study are the following:

• Hyaluronic acid
• Cone-beam computed tomography(CBCT) x-ray The patients with Grade II furcation will be divided into two groups. Both groups will have the same number of patients and the same procedure, such as the scaling root planning. However, the control group will use hyaluronic acid and membrane. The placebo group, on the other hand, will use hyaluronic acid without membrane and will use CBCT x-ray. The x-rays will be done at the beginning of the treatment. Then, two monitoring processes will be done. The first monitor will be done after three months. The data will be recorded. Then, after another three months, the patients will undergo an x-ray check again, and the data will be recorded. The goal is only to have the patients exposed to x-ray twice so they would not be compromised to the high dose of radiation. The evaluation to be done for the 3-month interval will only be clinical assessments.

Inclusion Criteria:

1. Selected teeth: Permanent first and second molars in the mandible.
