Clinical evaluation of alloderm for root coverage and colour match

Area of Science:

• Periodontology
• Regenerative Dentistry
• Aesthetic Dentistry

Background:

• Gingival recession treatment aims for predictable root coverage and optimal color match.
• Acellular dermal matrix (alloderm) is a potential substitute for connective tissue grafts.
• Limited data exists on alloderm's color match in highly pigmented populations.

Purpose of the Study:

• Evaluate alloderm effectiveness for root coverage procedures.
• Objectively analyze post-operative aesthetics using the Visual Analog Scale (VAS).

Main Methods:

• 14 patients (20-50 years) with Miller's class I or II gingival recession were included.
• 15 sites were treated with alloderm.
• Aesthetics and root coverage were assessed at 3 and 12 months.

Main Results:

• Mean root coverage of 85.56% (3 months) and 83.33% (12 months) was achieved.
• Patient-reported VAS scores for color match were 7.93 (3 months) and 8.13 (12 months).
• Observer-reported VAS scores for color match were 5.73 (3 months) and 6.87 (12 months).

Conclusions:

• Acellular dermal matrix (alloderm) is effective for treating gingival recession.
• Predictable root coverage and satisfactory aesthetic outcomes, including color match, can be achieved.
• Grafted sites showed melanization and blending with adjacent tissues by 1 year.
