Altered Passive Eruption of Teeth

altered passive eruption, gummy smile, aesthetic
Brief 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.
Detailed description
The primary aim of this study is to evaluate the prevalence of gummy smile, with particular focus on altered passive eruption, in a young adult population. Additionally, the study seeks to analyze key aesthetic and periodontal parameters in order to better understand their role in the etiology and clinical manifestation of excessive gingival display. Special attention is given to the second sextant, which is most frequently involved in gummy smile, to investigate the local distribution of these alterations and their diagnostic relevance. Furthermore, the study aims to explore the relationship between the extent of gingival exposure and variations in periodontal parameters, while also assessing the level of aesthetic, psychological, and social discomfort perceived by affected individuals. Data analysis will also allow the identification of potential individual anatomical factors, such as the position of the mucogingival junction and clinical crown dimensions, that may be associated with altered passive eruption. This is an observational epidemiological study designed to evaluate periodontal aesthetic parameters in patients attending their first clinical visit. The study will also assess the presence of aesthetic discomfort, investigate possible correlations, and explore the need for treatment related to second sextant conditions. Patients selected according to specific inclusion and exclusion criteria will undergo an operator-patient interview to collect anamnestic and clinical data. documentation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical crown length of maxillary anterior teeth | Baseline | Measurement of the clinical crown length (in millimeters) of maxillary anterior teeth, from the incisal edge to the gingival margin with a periodontal probe. |
