What this trial studies

This observational study investigates the impact of maxillomandibular deformities on the nutritional status of individuals aged 18 to 45. By analyzing dietary habits and nutritional health, the research aims to establish a correlation between the severity of jaw misalignment and nutritional deficiencies. Participants will complete questionnaires to provide insights into their oral functionality and food intake. The findings could lead to tailored nutritional guidelines for those with these deformities.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 45 with maxillomandibular deformities who are not undergoing orthodontic treatment.

Not a fit: Patients over 45 years old, those with chronic diseases requiring specific diets, or individuals with eating disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help develop specific nutritional guidelines to improve the health of individuals with maxillomandibular deformities.

How similar studies have performed: While there is limited data on similar studies, the exploration of nutritional impacts related to maxillofacial abnormalities is a relatively novel approach.
