Evaluation of Preventive Effect of Glass Ionomer Sealants and Laser Therapy on Dental Caries and Post-Eruptive Breakdown in Molars Affected by Molar Incisor Hypomineralisation (Randomized Clinical Trial)

What this Trial Is About

This research aims to evaluate and compare the preventive effects of glass ionomer sealant and laser therapy on dental caries and post-eruptive breakdown (PEB) in molars affected by molar incisor hypomineralisation (MIH). MIH is a defect of tooth enamel affecting one to four first permanent molars, sometimes involving incisor teeth, making these molars prone to damage and caries. The study involves children aged 6 to 9 years old with affected molars but no existing caries or PEB. Participants will be randomly divided into two groups: one receiving laser therapy using a specific laser device applied to the tooth surface for 20 seconds under safety measures, and the other receiving a glass ionomer sealant after surface conditioning, light curing, and occlusion adjustment. Both treatments are applied to the first permanent molars with MIH to prevent dental issues. Evaluations will occur at 6, 12, and 18 months after treatment. During the study, dental health including caries, PEB, sealant retention, and patient discomfort will be assessed at the scheduled follow-ups. Researchers will analyze the relationships between caries, PEB, and treatments using statistical methods. The main outcome measure is the presence of post-eruptive breakdown or dental caries after 21 months. Participation involves regular dental examinations and monitoring over this period.
