Use of a Glass Ionomer Sealant in First Permanent Molars Affected by Molar Incisor Hypomineralization

What this Trial Is About

Molar Incisor Hypomineralization (MIH) is a common developmental defect of the dental enamel affecting one or more permanent molars, usually the first permanent molars, and sometimes permanent incisors. The enamel in MIH is porous and has reduced mechanical strength, leading to problems like altered appearance, increased risk of plaque, cavities, breakdown of enamel, sensitivity, and difficulty in numbing affected teeth. This condition varies in severity and is challenging to manage, especially in molars which face higher chewing forces and are harder to clean. The study aims to assess the survival rate of glass ionomer sealants used as a preventive treatment on MIH-affected first permanent molars over 12 months. Sealants are applied to protect the teeth from cavities, with resin-based sealants preferred when the tooth is fully erupted and dry, while glass ionomer sealants are used temporarily when moisture control is difficult or the tooth is sensitive. This observational study will monitor how well glass ionomer sealants last on these teeth. Participants aged 6 to 10 years with MIH-affected molars showing lesions on the chewing surface will be followed for one year. Researchers will examine the teeth clinically to check the sealant's retention and durability. The study focuses on the sealant survival rate at 12 months, aiming to gather more evidence on the best preventive treatments for MIH-affected molars. Consent from parents or guardians is required, and participant cooperation is important for ongoing monitoring.
