About this study
This cross-sectional study aims to evaluate gingival phenotypes, cheiloscopic lip print patterns, and labial frenum attachment levels in healthy adult participants, and to investigate potential associations between these anatomical traits and gender.
Read the detailed description
Background: Anatomical variations of the periodontium and surrounding oral structures, such as gingival phenotypes, lip print patterns (cheiloscopy), and labial frenum attachments, exhibit individual diversity that can be influenced by demographic factors.
Objective: To assess and correlate gingival phenotypes, lip print patterns, and labial frenum attachment levels in a sample of healthy adult periodontal patients.
Methods: This observational, cross-sectional study will examine healthy participants. Clinical examinations will record gingival phenotype, classify lip print patterns using standard cheiloscopic classification, and evaluate labial frenum attachment levels. Statistical analysis will be performed to determine correlations and differences.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
