Methods: Methods: A cross-sectional survey among children aged 8-10years in Benghazi, Libya. MIH was assessed in Permanent teeth according to the European Association of Pediatric Dentistry criteria. Oral health quality of life was assessed using a validated Arabic version of COHIP-SF19. Data analysis was carried out using SPSS version 25. all statistical tests were conducted at p> 0.05. Results: Result: 1034 children were included in the study, with 162 children having MIH, mainly mild. A comparison of quality of life by MIH didn't show any significant differences. However, generally, children with MIH had a lower COHIP-SF19score. The number of MIH affected teeth was significantly and negatively correlated with the score of overall COHIP-SF19 and its psycho-social subscale score (p> 0.05). Conclusions: Conclusion: Although there is no significant association between MIH and oral health-related quality of life, children appear to have a low quality of life, and the impact is associated with a number of affected teeth.
