Abstract

Aim: This study assessed hypersensitivity in molars with molar incisor hypomineralization (MIH) after treatment with direct composite restorations (DCR) or preformed metal crowns (PMC).
Methodology: Sixty affected molars in Egyptian children (7-12 years) were treated and allocated into two groups. Hypersensitivity, restoration quality, treatment acceptability, health-related quality of life, parental satisfaction, and cost-effectiveness were measured.
Results: results showed that both treatments prevented hypersensitivity with no significant difference. However, PMC had better restoration quality after 12 months. DCR had higher treatment acceptability, while both treatments improved health-related quality of life after 6 months. All parents were satisfied with the treatment. For cost-effectiveness, PMC had a better effect compared to cost.
Conclusion: In conclusion, both DCR and PMC prevented hypersensitivity in molars with MIH. PMC had better restoration quality, while DCR had higher treatment acceptability. Both treatments improved health-related quality of life, and PMC was more cost-effective.
Clinical follow-up was performed for 12 months, and data were statistically analyzed. The study provides valuable insights into the treatment of MIH-affected molars in children.
