Nutritional Deficiencies and Associated Oral Health in Adolescents: A Comprehensive Scoping Review.

Introduction: The shift to processed foods in American diets has increased vitamin and mineral deficiencies among adolescents, impacting growth and health, often manifesting as oral lesions. This review study aimed to explore the link between nutritional deficiencies and adolescent oral health to improve guidance and prevent long-term issues.

Methods: A systematic review of literature from 2013 to 2023 was conducted on adolescents aged 10-19 years, using PRISMA guidelines. Searches in PubMed, Web of Science, Dentistry & Oral Sciences Source-Ebscohost, and Scopus included peer-reviewed articles, excluding reviews and non-empirical studies. Data were screened and extracted with independent reviews for accuracy.

Results: Malnutrition strongly correlates with poor oral health. Undernourished children have a 60% increase in dental caries, exacerbated by high sugar intake. Early malnutrition delays dental eruption, temporarily protecting against caries, while stunting and infections cause enamel defects. Chronic conditions like cerebral palsy and celiac disease worsen oral health, with risks persisting into adulthood.

Conclusions: Nutritional deficiencies and oral health are interconnected, requiring integrated healthcare. Early interventions and holistic strategies can improve outcomes and reduce long-term burdens. Comprehensive health education and routine dental evaluations are essential for prevention and treatment, enhancing health across all demographics.
