Coronally Advanced Flap With Alloderm Versus Coronally Advanced Flap With Micro-needling on RT1 Gingival Recession

Not Applicable

• Conditions: Recession, Gingival; Gingival Recession; Thin-gingiva
• Interventions: Procedure: coronally advanced flap combined with Alloderm; Procedure: Root coverage using coronally advanced flap combined with micro-needling

• Registration Number: NCT05470660
• Lead Sponsor: Cairo University

Brief Summary

This study aims to assess the effect of micro-needling together with coronally advanced flap procedure on the gain of gingival thickness (GT) and keratinized tissue width (KTW) and compare it to Alloderm with coronally advanced flap procedure in the management of thin periodontal phenotype associated with recession type 1 (RT1)

Detailed Description

Gingival or periodontal diseases were found to occur more likely in patients with a thin gingival biotype. The periodontal phenotype was also found to show stronger correlation with gingival thickness rather than keratinized tissue width and papilla height. Moreover, the thin gingiva was usually found to be associated with thin bony plate with potential for dehiscence and fenestration and hence was thought to be at risk for recession after trauma.

Several techniques have been recommended for the treatment of gingival recession. One of the most predictable outcome is associated with the use of a coronally advanced flap and acellular dermal matrix graft.

Treatment of thin periodontal phenotype through the conjunction of i-PRF and micro-needling may be a first move of the non-surgical approach for improving the gingival thickness. Micro-needling was proved to be generally an effective and safe therapeutic option for numerous dermatologic conditions as clinical improvement of scars, striae, and rhytids with appropriate recovery and limited side effects. The controlled dermal wounding and stimulation of the wound healing cascade through Micro-needling was found to enhance collagen production and thus was responsible for the clinical results obtained.

Therefore, this study will be aiming to compare the effect of micro-needling on the gingival thickness in root coverage procedures. It will also provide an insight of its effect on the patient related factors and the root coverage parameters.

Arm && Interventions

Group	Intervention	Description
coronally advanced flap combined with Alloderm	coronally advanced flap combined with Alloderm	modified coronally advanced flap will be performed in sites of recession defects in Association with alloderm to cover the exposed root and 3 mm of connective tissue mesial and distal to it.
Root coverage using coronally advanced flap combined with micro-needling	Root coverage using coronally advanced flap combined with micro-needling	modified coronally advanced flap will be performed in sites of recession defects, then micro-needling will be performed after 1 month from the coronally advanced flap procedure to ensure the initial flap healing

Primary Outcome Measures

Name	Time	Method
Gingival thickness (GT) in mm	6 months	Gingival thickness (GT) will be specified at a mid-buccal location approximately 1 mm apical to the probing depth (PD) level with a #15 endodontic spreader. The reamer will be pierced, perpendicularly to the mucosal surface, through the soft tissue with light pressure until a hard surface is felt. The silicone disk stop will then be placed in tight contact with the soft tissue surface and fixed by a drop of cyanoacrylate adhesive; after careful removal of the reamer, penetration depth will be measured with a caliper to the nearest 0.1 mm gingival thickness changes will be calculated after 6 months

Secondary Outcome Measures

Name	Time	Method
Keratinized tissue width (KTW) in mm	6 months	Keratinized tissue (KT) will be measured from the most apical point of the gingival margin to the mucogingival junction measurements will be recorded at baseline and after 6 months
Gingival Recession Depth (RD) in mm	6 months	Will be measured from the Cemento-enamel Junction to the most apical extension of the gingival margin.
Clinical Attachment Level (CAL) in mm	6 months	Will be measured from the Cemento-enamel Junction to the bottom of the gingival sulcus at baseline and 6 months
Gingival Recession Width (RW) in mm	6 months	Will be measured horizontally between the borders of the recession at the level of Cemento-enamel Junction.
Percentage of root coverage	6 months	Preoperative vertical recession - Postoperative vertical recession/preoperative vertical recession) x 100.
