Intraosseous vs Infiltration Anesthesia in Molar-Incisor Hypomineralization (MIH) Children

This study is comparing two types of dental anesthesia — injecting numbing medication directly into the bone (intraosseous) versus the traditional injection into the gum tissue (infiltration) — for children with a condition called Molar-Incisor Hypomineralization (MIH). MIH causes teeth to have weaker enamel that is often very sensitive and hard to numb with regular injections. **You may be eligible if:** - You are a child aged 6 to 12 years old - You are generally healthy with no known allergies - You have MIH affecting both upper first molars in a moderate to severe way - You score 3 or 4 on the Frankl Behavior Scale (meaning you are cooperative or very cooperative at the dentist) - You and your parent or guardian consent to participate - You have no urgent dental pain at the time of the study **You may NOT be eligible if:** - There are no specific exclusion criteria listed beyond not meeting the above requirements Talk to your doctor to see if this trial is right for you.
