Conditions
Gingival Recession
Interventions
Procedure: Pinhole surgical technique and tunnel technique in a split mouth design
Registration Number
NCT04513041
Lead Sponsor
Mohanad Al-Sabbagh
Brief Summary

This is an assessor-blinded split-mouth randomized clinical study to compare root coverage and gingival tissue thickness following two different surgical procedures for non-autologous grafting: the pinhole surgical technique (PST) and tunnel technique.

Detailed Description

Each patient will undergo both surgeries on either quadrant; the PST and tunnel technique. The site will be randomized to receive either type of surgeries. Both types of surgeries are considered minimally invasive procedures to obtain root coverage for gingival recession. Both surgeries are clinically utilized in clinical practice and yield comparable results according to the literature, however, No prospective studies are published to compare between the outcomes of both techniques. patients will receive intra oral scan before the surgery and 6 months after the surgery to compare change in root coverage and gingival thickness outcomes between the two techniques. Post operative pain as well as patient satisfaction will be measured by visual analog scale and compared between the two techniques. Patients will be monitored at different time points to asses healing.

Primary Outcome Measures
NameTimeMethod
Change in gingival thickness6 months (pre operative and at the 6-month follow-up visit)

Two digital scans (pre- and 6-month post-operative) will be overlapped to measure the change in gingival thickness.

Change in gingival recession6 months (pre operative and at the 6-month follow-up visit)

Two digital scans (pre- and 6-month post-operative) will be overlapped to measure the change in gingival recession.

Secondary Outcome Measures
NameTimeMethod
Change in sulcus probing depth6 months (pre operative and at the 6-month follow-up visit)

During a clinical exam, a sulcus will be used to measure the depth from the free gingival margin to the base of the sulcus pre- and 6-months post-operative.

Change in papillary recession6 months (pre operative and at the 6-month follow-up visit)

Two digital scans (pre- and 6-month post-operative) will be overlapped to measure papillary gingival recession.

Change in root coverage6 months (pre operative and at the 6-month follow-up visit)

Two digital scans (pre- and 6-month post-operative) will be overlapped to measure the complete elimination of gingival recession.

Change in zone of keratinized tissue6 months (pre operative and at the 6-month follow-up visit)

During a clinical exam, the zone of keratinized tissue will be measured during the pre- and post-operative clinical exam.

Change in bleeding on probing.6 months (pre operative and at the 6-month follow-up visit)

The presence or absense of bleeding during probing during will be noted during the pre- and post-operative clinical exam.

Aesthetic satisfaction1 day

A Visual Analog Score for aesthetic satisfaction will be used to assess patient satisfaction 6 months after surgery. Scores range from 0-10; higher scores indicate greater satisfaction.

Post-operative pain1 week

A Visual Analog Score for pain will be used to assess post-operative pain one week after surgery. Scores range from 0-10; higher scores indicate greater pain.

Change in clinical attachment.6 months (pre operative and at the 6-month follow-up visit)

Clinical attachment will be calculated during the pre- and post-operative clinical exam.
