30 agosto 2026 aggiornato da: Mai Magdy Abu El Eneen, Cairo University

The Effect of Vertically Coronally Advanced Flap With Sub-epithelial Connective Tissue Graft Versus Coronally Advanced Flap With Sub-epithelial Connective Tissue Graft on Gingival Recession: A Randomized Clinical Trial

The aim of this randomized clinical trial will be to assess the change in recession depth after using a vertically coronally advanced flap with sub-epithelial connective tissue graft compared to a coronally advanced flap with sub-epithelial connective tissue graft after 6 months.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Comparatore attivo: Coronally Advanced flap combined with sub-epithelial connective tissue graft
The combination of a SCTG with CAF was regarded as the gold standard for root coverage procedures

Sperimentale: Vertically Coronally Advanced flap combined with sub-epithelial connective tissue graft
Vertically coronally advanced flap combined with a subepithelial connective tissue graft for the treatment of gingival recession defects. The procedure involves preparation and coronal advancement of a vertically designed flap to cover the exposed root surface, followed by placement of a subepithelial connective tissue graft beneath the flap to enhance soft-tissue thickness and root coverage.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in recession depth (mm)
Lasso di tempo: at Baseline and 6 months
Change in recession depth in millimeters will be measured using a UNC-15 periodontal probe as the distance from the cementoenamel junction towards the most apical extension of the gingival margin
at Baseline and 6 months

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Gingival Recession Width (mm)
Lasso di tempo: at baseline and 6 months
Gingival recession width will be measured in millimeters using a UNC-15 periodontal probe as the distance from the base of the mesial to the distal papillae along the cementoenamel junction.
at baseline and 6 months
Keratinized Tissue Width (mm)
Lasso di tempo: at Baseline and 6 months
Keratinized tissue width will be measured in millimeters using a UNC-15 periodontal probe from the gingival margin at the deepest recession point till the mucogingival junction (MGJ), which will be identified using the roll technique
at Baseline and 6 months
Keratinized Tissue Height (mm)
Lasso di tempo: at Baseline and 6 months
Keratinized tissue height will be measured in millimeters using a UNC-15 periodontal probe from the gingival margin to the mucogingival junction.
at Baseline and 6 months
Probing Depth (mm)
Lasso di tempo: at Baseline and 6 months
Probing depth will be measured in millimeters using a UNC-15 periodontal probe as the distance from the base of the gingival crevice to the marginal gingiva.
at Baseline and 6 months
Gingival Thickness (mm)
Lasso di tempo: at Baseline and 6 months
Gingival thickness will be measured in millimetres using endodontic spreader no. 15 with a silicon disk stopper will be performed apical to the gingival margin by 2 mm at the middle of the long axis of the tooth mesio-distally using a UNC-15 periodontal probe.The depth of penetration will be measured using a ruler with precision up to the nearest 0.5 mm.
at Baseline and 6 months
Recession Reduction (mm)
Lasso di tempo: at Baseline and 6 months
Recession reduction will be calculated by comparing the initial gingival recession depth and gingival depth after treatment using a UNC-15 periodontal probe.
at Baseline and 6 months
Clinical Attachment Level (mm)
Lasso di tempo: at Baseline and 6 months
Clinical attachment level will be identified using a UNC-15 periodontal probe as the distance from the cementoenamel junction to the bottom of the gingival sulcus.
at Baseline and 6 months
Complete Root Coverage (%)
Lasso di tempo: at 6 months
Complete root coverage will be assessed by calculating the percentage of cases exhibiting a gingival margin that was either level with or positioned coronally to the cementoenamel junction in each group.
at 6 months
Bleeding on Probing (+/-)
Lasso di tempo: at Baseline and 6 months
Bleeding on probing (BOP) will be measured using an UNC-15 periodontal probe, gently probing the gingival crevice, beginning inter-proximally from the mesial aspect and moving towards the distal. A positive finding for BOP will be recorded when bleeding occurred within 10s.
at Baseline and 6 months
Plaque Index (scores 0, 1, 2, 3)
Lasso di tempo: at Baseline and 6 months

Plaque index will be determined by drying the teeth in each quadrant with a gentle air blast, where the visibility of dental plaque and supragingival calculus will be noted. Each four tooth surfaces (buccal, lingual, mesial and distal) will be scored from 0 to 3, then scores of the four areas will be added and divided by four to give the average plaque index for each tooth.

Scores:

0 : No plaque

1 : A film of plaque adhering to the free gingival margin and adjacent area of the tooth. The plaque may be seen in situ only after application of disclosing solution or by using the probe on the tooth surface.

2: Moderate accumulation of soft deposit s within the gingival pocket, or the tooth and gingival margin, which can be seen with the naked eye.

3: Abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin.

at Baseline and 6 months
Post-Operative Pain (VAS) Visual Analogue Scale Questionnaire
Lasso di tempo: Surgical day and days 1, 3, 7, and 14 after surgery
Post-operative pain will be indirectly evaluated on the basis of the mean consumption (in mg) of analgesics (ibuprofen). A questionnaire will be given to each patient; it will be divided into two parts to be completed in different time periods: the first part, regarding the post-operative discomfort and bleeding will be completed 1 week after the surgery based on a visual analogue scale of 100 mm.Postoperative pain will be assessed using a 100-mm Visual Analogue Scale, ranging from 0 mm (no pain) to 100 mm (worst imaginable pain), with higher scores indicating greater pain.
Surgical day and days 1, 3, 7, and 14 after surgery
Patient Esthetic Satisfaction (RES) Root Coverage Esthetic Score
Lasso di tempo: at 6 months
Patient aesthetic satisfaction will be assessed using the root coverage esthetic score (RES) at the 6 months follow up visit. The following five parameters will be evaluated: gingival margin level (0 = failure of root coverage; 3 = partial root coverage; 6 = complete root coverage), marginal tissue contour (0 = irregular; 1 = proper), soft tissue texture (0 = presence of scar/keloid; 1 = absence of scar/ keloid), mucogingival junction (MGJ) (0 = MGJ not aligned; 1 = MGJ aligned), and gingival color (0 = color differs from adjacent teeth; 1 = normal color and integration). A total RES score will be calculated by adding these 5 components
at 6 months
Mean Percentage of Root Coverage (mRC) %
Lasso di tempo: (subtraction of gingival RD at baseline from gingival RD at 6 months divided by gingival RD at baseline) multiplied by 100
Mean percentage of root coverage (mRC) will be calculated after 6 months as the percentage reduction in gingival recession depth from baseline to 6 months post-treatment, using the following formula: mRC (%) = [(RD₀ - RD6) / RD₀] × 100, where RD₀ represents the gingival recession depth at baseline and RD6 represents the gingival recession depth at 6 months post-treatment.
(subtraction of gingival RD at baseline from gingival RD at 6 months divided by gingival RD at baseline) multiplied by 100
