Effect of Hyaluronic Acid in the Treatment of Periodontal Pockets

Not Applicable

Completed

• Conditions: Chronic Periodontitis With Infra-bony Defects
• Interventions: Drug: Hyaluronic Acid

• Registration Number: NCT02170857
• Lead Sponsor: Damascus University

Brief Summary

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.

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.

Arm && Interventions

Group	Intervention	Description
Open Curettage with Hyaluronic Acid	Hyaluronic Acid	Hyaluronic Acid injection will be employed in conjunction with the ordinary surgical procedure.

Primary Outcome Measures

Name	Time	Method
Change in the Clinical Attachment Loss (CAL)	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	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.
Vertical bone fill	at 12 months post-surgery	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.

Secondary Outcome Measures

Name	Time	Method
Mesiodistal distance	at 12 months post-surgery	Mesiodistal distance: is the distance between mesial wall and distal wall of the infra-bony pocket.
Change in the Pocket Probing Depth (PPD)	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	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.
Buccolingual distance	at 12 months post-surgery	Buccolingual distance: is the distance between buccal wall and lingual wall of the infra-bony pocket.
Depth of infra-bony defect	at 12 months post-surgery	Depth of infra-bony defect: is the distance between the base of the infra-bony defect and the most coronal level of alveolar crest.
