Recent advances in digital technology have led to the emergence of precise methods for measuring gingival recession and tissue thickness. This study aimed to compare digital measurement methods and conventional periodontal probe measurements for the assessment of gingival recession influenced by the gingival phenotype.

This study involved 128 gingival recession sites from 28 systemically healthy patients aged 18-45 years. The participants were categorized into two groups on the basis of gingival thickness. The plaque index, gingival index, probing depth, clinical attachment level, gingival recession depth, and gingival recession width, and keratinized gingival thickness and width were measured using a manual periodontal probe and an intraoral optical surface scanner. Statistical analysis was performed with nonparametric tests because the data were not normally distributed. P<0.05 indicated statistical significanct.

Inclusion Criteria: The study included systemically healthy subjects aged 18-45 years with systemic disease or systemic disease under control.

Exclusion Criteria: The exclusion criteria were as follows:

• Patients with a history of radiotherapy,
• Patients with chemotherapy,
• Immunosuppressive use,
• Tobacco use,
• Smoking,
• Patients with labially exposed teeth and teeth with prominent root protrusions,
• Pregnancy and lactation,
• Patients with uncontrolled diabetes,
• Patients with postorthodontic extractions,
• Patients with gingival recession, .Patients with gingival enlargement caused by piercing and nail-biting habits.

The study included 128 gingival recessions at 128 sites in 28 systemically healthy patients aged 18-45 years old. The patients were divided into two groups according to the thickness of the gingiva in the teeth with gingival recession.
