NCT07548398 · tracked via the Priya Life Science Italy tracker
Condition(s) studied
Altered Passive Eruption of Teeth
Investigational drug(s) / intervention(s)
Clinical assessment
Clinical assessment: Non-invasive clinical evaluation including measurement of aesthetic indices (PES/WES), and intraoral photographic documentation.
Study summary
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
Inclusion Criteria:
* Male and female subjects;
* Age between 18 and 50 years;

* Patients with no history of orthodontic treatment;
* Patients without gingival hypertrophy or hyperplasia.
Exclusion Criteria:
* 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;
* Patients taking medications associated with gingival hypertrophy or -hyperplasia;
* Patients unwilling to provide informed consent;
* Patients with fixed or removable prostheses in the second sextant;
* Patients with a history of surgical procedures in the second sextant;
* Patients with uncontrolled diabetes or neuropsychiatric disorders;
* Patients with infectious diseases;
* Pregnant or breastfeeding women, or those with suspected pregnancy;
* Patients taking bisphosphonates;
* Oncologic patients and those undergoing head and neck radiotherapy or receiving chemotherapy;
* Patients with alcohol or drug abuse.
Primary outcome measure(s)
- Gingival display during smiling — Baseline (single visit)
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. - Prevalence of altered passive eruption (APE) — Baseline
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)
