About this study
Official title: A Randomized Controlled Trial to Evaluate the Effect of Hyaluronic Acid on Infra-bony Defects: A Radiographic and Clinical Study.
The aim of this study is to evaluate the effect of hyaluronic acid in the surgical treatment of periodontal pockets in people with gum disease.
This research consists of clinical and radiographic studies. Participants should have symmetric periodontal pockets in the upper or lower jaw.
Participants will be treated surgically using hyaluronic acid on one side of the jaw.
Clinical indexes and radiographic cone-beam computed tomographic (CBCT) images will be taken for each participant before surgical treatment and 12 months after surgical treatment.
Read the detailed description
The aim of this study is to evaluate the effect of hyaluronic acid in the surgical treatment of infra-bony pockets in chronic periodontitis patients.
This research consists of clinical and radiographic studies.
1- The clinical study: is a randomized controlled trial with a split mouth technique.
Chronic periodontitis patients with Infra-bony pockets will be collected from the Department of Periodontics in faculty of dentistry - Damascus university.
Participants should have symmetric infra-bony pockets in the upper or lower premolar area with pocket probing depth more than 6 mm.
Participants will be treated surgically using open flap curettage.
Open flap curettage will be done for each patient in both sides of the jaw, but hyaluronic acid will be used in one of the two sides with random allocation of the site that in going to be treated with hyaluronic acid.
Plaque index, gingival index, bleeding on probing, tooth mobility index, pocket probing depth and clinical attachment loss will be taken for each participant four times; before surgical treatment, 3 months, six months and 12 months after surgical treatment.
Radiographic study: will be done using CBCT radiography technique. CBCT will be taken for each participant before and after 12 months of surgical treatment. Different distances, vertical bone fill and depth of infra-bony defect will be measured on CBCT images.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hyaluronic AcidDrug
This material will be used in conjunction with the ordinary surgical procedure
| Study group | Role | What they receive |
|---|---|---|
| Open Curettage Only | No intervention | patients will be treated by the conventional surgical method, i.e. open curettage without injecting any material. |
| Open Curettage with Hyaluronic Acid | Experimental | Hyaluronic Acid injection will be employed in conjunction with the ordinary surgical procedure. Receives: Drug: Hyaluronic Acid |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in the Clinical Attachment Loss (CAL)
Clinical Attachment Loss (CAL): it is the distance between the cement-enamel junction of the tooth and the bottom of the pocket.
CAL will be performed using a dental probe.
Measured: CAL will be measured at four times in this study: one week before surgical treatment, 3 months post-surgery, six months post-surgery and 12 months post-surgery
Vertical bone fill
Vertical bone fill: it is the distance between the base of the infra-bony defect and cement-enamel junction before surgery minus the distance between base of the infra-bony defect and cement enamel junction after surgery.
It will be measured on CBCT images.
Measured: at 12 months post-surgery
Secondary outcomes (4)
Change in the Pocket Probing Depth (PPD)
Pocket Probing Depth (PPD): it is the distance from the gingival margin to the bottom of the pocket at four sites per tooth. PPD will be measured using a dental probe.
Measured: PPD will be measured at four times in this study: one week before surgical treatment, 3 months post-surgery, six months post-surgery and 12 months post-surgery
Buccolingual distance
Buccolingual distance: is the distance between buccal wall and lingual wall of the infra-bony pocket.
Measured: at 12 months post-surgery
Mesiodistal distance
Mesiodistal distance: is the distance between mesial wall and distal wall of the infra-bony pocket.
Measured: at 12 months post-surgery
Depth of infra-bony defect
Depth of infra-bony defect: is the distance between the base of the infra-bony defect and the most coronal level of alveolar crest.
Measured: at 12 months post-surgery

Who may be eligible to take part?
The sponsor lists 8 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Syria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in the Clinical Attachment Loss (CAL) (time frame: CAL will be measured at four times in this study: one week before surgical treatment, 3 months post-surgery, six months post-surgery and 12 months post-surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02170857, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2017; AzTrials last refreshed its copy on 8 Nov 2026.
