Investigating the Relationship Between Ultra-Processed Food Consumption and Caries and Periodontal Disease

• Status: Not Yet Recruiting
• Phase: —
• Study type: Observational
• Enrollment: 200 (estimated)
• Sponsor: Recep Tayyip Erdogan University Training and Research Hospital · Academic / Other
• Sex: All
• Age: 18 Years – 65 Years
• Healthy volunteers: Accepted

Summary

The goal of this observational study is to examine the potential relationship between ultra-processed food consumption and the presence of dental caries and periodontal disease, and to evaluate the role of the Ultra-Processed Food Index (UPFI) in this association. The main question it aims to answer is: Does increased consumption of ultra-processed foods raise the risk or severity of dental caries and periodontal disease in individuals? Participants will include individuals within a specified age range who voluntarily agree to participate in the study. Oral health status will be assessed through standard clinical parameters, including the presence of caries, plaque index, probing pocket depth, clinical attachment loss, and bleeding on probing. Dietary habits will be evaluated using a validated food frequency questionnaire, and individual UPFI scores will be calculated. The study will aim to observe and analyze the effects of ultra-processed food consumption on oral health outcomes.

Detailed description

This observational study will aim to investigate the association between ultra-processed food consumption and oral health outcomes, specifically focusing on dental caries and periodontal disease. Participants will include individuals within a defined age range who consent to take part in the study. Oral health status will be clinically assessed using standard parameters such as the presence of carious lesions, plaque index, probing pocket depth, clinical attachment loss, and bleeding on probing. Dietary intake will be evaluated using a validated food frequency questionnaire, and individual Ultra-Processed Food Index (UPFI) scores will be calculated. The study will analyze whether a higher intake of ultra-processed foods is associated with increased risk or severity of dental caries and periodontal disease. Findings from this study are expected to contribute to a better understanding of the impact of modern dietary patterns on oral health and highlight the importance of nutritional strategies in preventive dentistry.
