A minimal interventive protocol using antimicrobial photodynamic therapy on teeth with molar incisor hypomineralization: A case report

Molar incisor hypomineralization (MIH) is a qualitative developmental defect of enamel that occurs during the mineralization phase. Patients with MIH have increased risk of caries, hypersensitivity, and restoration failures. The present case report describes the treatment of a 10‐year‐old patient exhibiting two teeth with atypical carious lesions. A minimal interventive protocol was instituted combining antimicrobial photodynamic therapy and the selective chemical–mechanical removal of the carious tissue using the product Papacárie Duo®. This protocol is promising for the decontamination and control of hypersensitivity in teeth with MIH. This clinical case report describes a minimal intervention protocol combining antimicrobial photodynamic therapy and the selective chemical–mechanical removal of carious tissue on teeth with molar incisor hypomineralization. Antimicrobial photodynamic therapy was used for the purpose of decontamination and had a secondary effect of reducing dentin hypersensitivity after restorative treatment. This treatment protocol can be an important contribution to the scientific community and pediatric dentists.
