Er:YAG Laser Versus Conventional Cavity Preparation in Children With Molar-Incisor Hypomineralization
Sponsor: Ege University
Summary
This randomized clinical trial compares Er:YAG laser-assisted and conventional rotary cavity preparation in children aged 6-12 years with molar-incisor hypomineralization. A total of 52 children are randomly assigned to one of the two preparation methods. The study evaluates pain, dental anxiety, sensory experiences, physiological responses, patient comfort, need for local anesthesia, and procedure duration. Postoperative discomfort and the clinical performance of restorations are also assessed during follow-up visits at 1, 3, and 6 months.

Interventions
Er:YAG Laser-Assisted Cavity Preparation
Cavity preparation was performed using an Er:YAG laser (2940 nm). Enamel and dentin were selectively removed using laser parameters appropriate for each dental tissue. The prepared cavity was subsequently restored using an adhesive system and resin composi
Conventional Rotary Cavity Preparation
Cavity preparation was performed using conventional high-speed rotary instruments and diamond burs. The prepared cavity was subsequently restored using the same adhesive system and resin composite used in the laser group.
