About this trial

This observational epidemiological study aims to assess the prevalence of gummy smile and altered passive eruption in a young adult population, with a focus on the second sextant. Periodontal and aesthetic parameters, along with patient-reported discomfort, will be analyzed to identify potential correlations and underlying anatomical factors.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Male and female subjects;

Age between 18 and 50 years;

Periodontally healthy subjects;

Patients with no history of orthodontic treatment;

Disqualifiers

Age < 18 or > 50 years;

Patients diagnosed with Stage I-IV periodontitis;

Patients currently undergoing orthodontic treatment;

Patients with severe dental crowding in the second sextant;

Trial population

The population will include individuals with and without excessive gingival display, in order to assess the prevalence of gummy smile and its association with altered passive eruption and related anatomical and aesthetic parameters. Particular attention will be given to the second sextant, which represents the area most frequently involved in gingival display. All participants will undergo a non-invasive clinical and photographic assessment aimed at evaluating gingival exposure, clinical crown dimensions, and other relevant anatomical features. In addition, patient-reported outcomes regarding aesthetic perception and psychosocial impact will be collected.

Trial outcomes

Primary outcomes

1

Gingival display during smiling

Quantitative assessment of gingival display during posed smile, measured as the vertical distance (in millimeters) between the inferior border of the upper lip and the gingival margin of the maxillary central incisors. Continuous variable (mm), measured using a calibrated periodontal probe and standardized intraoral photographs.

Time frame
Baseline (single visit)
2

Prevalence of altered passive eruption (APE)

Assessment of the presence of altered passive eruption based on clinical crown dimensions and gingival margin position relative to anatomical landmarks. Measurement scale: Categorical variable (Presence/Absence)

Time frame
Baseline

Secondary outcomes

1

Clinical crown length of maxillary anterior teeth

Measurement of the clinical crown length (in millimeters) of maxillary anterior teeth, from the incisal edge to the gingival margin with a periodontal probe.
