Summary
This summary is machine-generated.Most Peruvian individuals exhibit acceptable facial and maxillary dental midline alignment, though perfect coincidence is less common. This finding highlights the need for orthodontic evaluation for optimal esthetics and function.
Area Of Science
- Dentistry
- Orthodontics
- Facial Aesthetics
Background
- Assessing the coincidence between facial and maxillary dental midlines is crucial for diagnosing and treating dental and facial asymmetries.
- Understanding these relationships in diverse populations like Peruvians contributes to global orthodontic knowledge.
Purpose Of The Study
- To quantify the prevalence of perfect and acceptable coincidence between the facial midline and the maxillary dental midline in a Peruvian population.
- To explore potential associations between midline coincidence and facial biotypes or sex.
Main Methods
- A cross-sectional study included 279 Peruvian adults (18-30 years) with complete permanent dentition.
- Frontal photographs were analyzed using specialized software to measure midline coincidence (perfect and accepted deviation ≤2mm).
- Facial biotypes were classified, and statistical analyses (chi-square, logistic regression) were performed.
Main Results
- 95.7% of participants showed acceptable (≤2mm deviation) coincidence between facial and maxillary dental midlines.
- Only 23.3% exhibited perfect midline coincidence.
- No significant associations were found between midline coincidence and facial biotype or sex.
Conclusions
- The majority of the Peruvian individuals studied have acceptable, though not always perfect, alignment of their maxillary dental midline with the facial midline.
- Orthodontic intervention may be necessary for individuals with significant midline discrepancies to achieve optimal occlusal relationships and facial esthetics.
- This study provides valuable data on dental midline esthetics within the Peruvian population.
