简要总结
Compromised first permanent molars (FPM), whether diagnosed with severe molar incisor hypomineralization (MIH), irreversible pulpities, or necrosis, require frequent re-treatment consequently entering the restorative cycle, which leads to their inevitable extraction and implant placement. Extraction of compromised first permanent molars in 8-10-year-old children allows the mesial migration of the second permanent molars during their eruption, thereby favoring spontaneous space closure as a permanent solution.
详细描述
Extraction of compromised first permanent molars in children decreases the burden of repeated restorative procedures for theses molars, which will eventually need frequent repair. This will end in their inevitable extraction with its consequences. The extraction of the FPM will be delivered by Nour Wahba, Dina Darwish, and Basma Nagi, lecturers in Pediatric Dentistry and Dental Public Health Department, faculty of Dentistry, Ain Shams University.All patients will be recalled for follow-up yearly for three-years. The first follow-up will be done after 6months to perform the Quality of life questionnaires. The position of the second permanent molar will be checked clinically and radiographically to evaluate the space between second premolar and the second molar.
