Our featured study explores how dental aesthetics, clinical conditions, and sociodemographic factors influence dental self-confidence among Indonesian adolescents.

Focusing on 274 high school students, the study uses the Index of Orthodontic Treatment Need (IOTN) to investigate the important relationship—and potential gap—between objective clinical orthodontic needs and adolescents’ subjective perceptions of their dental appearance.

🔬 𝗞𝗲𝘆 𝗛𝗶𝗴𝗵𝗹𝗶𝗴𝗵𝘁𝘀

🦷 Clinical Impact: Severe orthodontic treatment needs, reflected by higher Dental Health Component (DHC) scores, were strongly associated with lower dental self-confidence.

👧 The Gender Gap: Female adolescents reported significantly lower dental self-confidence compared with their male peers.

👩‍👧 Maternal Education: Lower maternal education was associated with lower dental self-confidence, highlighting the potential influence of family and social factors on adolescents' self-perception.

💬 Functional vs. Emotional Factors: Interestingly, aesthetic scores and physical concerns, such as difficulties with chewing or speech, showed no significant association with dental self-confidence.

This research highlights the importance of looking beyond clinical dental conditions. Effective oral health and public health programmes should consider both the clinical and emotional dimensions of dental care to better support adolescent well-being.
