Intraosseus Injection Using Extra-short Needle Combined With Infiltration in Pediatric Patients With Molar Incisor Hypomineralization

Effectiveness of Intraosseus Injection Using Extra-short Needle Combined With Infiltration in Pediatric Patients With Molar Incisor Hypomineralization (A Randomized Controlled Clinical Trial)

Background: Effective pain control is crucial in managing pediatric dental patients. Molar-incisor hypomineralization (MIH), marked by enamel defects and dentin hypersensitivity, often hinders effective local anesthesia. Traditional injection methods may fall short, causing discomfort and complicating treatment. Combining infiltration with intraosseous injection using an extra-short 31-G needle may offer a more effective alternative.

Purpose: To compare the effectiveness of combined infiltration and intraosseous injection with an extra-short 31-G needle versus conventional techniques in eliminating pain during
