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.

128
Gingival recession sites were scanned with an intraoral optical surface scanner, and STL images were recorded. The images were imported into image analysis software. The depth, width and area of gingival recession were calculated using Autocat program.

keratinized gingival thickness
Keratinized gingival thickness refers to the vertical measurement of the gingival tissue that extends from the free gingival margin to the mucogingival junction, characterized by a keratinized epithelial layer which provides enhanced protection and stability to the underlying periodontal structures.
Time frame: Baseline
keratinized gingival width
Keratinized gingival width refers to the horizontal dimension of the gingival tissue that is keratinized, measured from the free gingival margin to the mucogingival junction.
Time frame: Baseline
Gingival recession depth
Gingival recession is the apical migration of the gingival margin away from the cemento-enamel junction (CEJ), resulting in the exposure of the root surface of a tooth.
Time frame: Baseline
Gingival recession width
Gingival recession width refers to the horizontal measurement from the exposed cemento-enamel junction (CEJ) to the apical point of the gingival margin, indicating the extent of root surface exposure.
Time frame: Baseline
Plaque index
The plaque index assesses the amount of dental plaque visible on the vestibular and lingual surfaces of all teeth
Time frame: Baseline
Gingival index
This measurement is based on the presence or absence of bleeding on gentle probing
Time frame: Baseline
Bleeding on probing
Bleeding, leading sign of inflammation inside the connective tissue, is a critical factor for pocket depth measurements, and with other variable factors prevents making reproducible measurements.
Time frame: Baseline
Periodontal pocket depth
A pathologically deepened gingival sulcus around a tooth at the gingival margin.
Time frame: Baseline
Clinical attachment level
CAL is calculated by subtracting the gingival margin level from the probing depth.
Time frame: Baseline
