The purpose of this study was to investigate dental students’ and residents’ awareness, clinical experience, diagnostic confidence, and educational needs regarding Molar-Incisor Hypomineralization (MIH), to inform effective diagnostic training strategies. A descriptive cross-sectional study was conducted among third-year (n = 65), fourth-year (n = 80) dental students, and residents (n = 74; pediatric dentistry, conservative dentistry, and the other specialties) at Chonnam National University from September to October 2024. A structured self-report questionnaire was used for data collection. Data were analyzed using chi-square, Fisher’s exact test, t-tests, ANOVA, and logistic regression (p < 0.05). Overall, familiarity with MIH was 69.0% among students and 98.6% among residents. Knowledge of clinical features (students 44.1%, residents 75.7%) and diagnostic criteria (students 3.4%, residents 17.6%) was limited. Only 17.2% of students and 43.2% of residents had observed MIH clinically. Most respondents reported difficulty distinguishing MIH from other conditions (students 89.0%, residents 82.4%). Confidence in diagnosing MIH was low among respondents (students 1.71 ± 0.71, residents 2.28 ± 0.85). Most students (87.6%) and residents (93.2%) indicated a need for additional MIH-related education. Clinical observation and knowledge of diagnostic criteria were significantly associated with diagnostic confidence (p < 0.0001). Dental students and residents showed relatively high awareness of MIH but limited knowledge of diagnostic criteria and low selfreported diagnostic confidence. These findings highlight the need for practiceoriented educational programs to strengthen MIH diagnostic competence, suggesting targeted curricular improvements within dental education.
