Esthetic Impact of Different Minimally Invasive Approaches on Hypomineralized Permanent Anterior Teeth

The aim of the study is to determine the effectiveness of minimally invasive treatments in reducing the visible enamel opacities on permanent anterior teeth in children aged from seven to twelve years with hypomineralized lesions. A secondary purpose is to evaluate patient satisfaction and the psychosocial impact of the treatment on the esthetic perception of the treated children. The results of all the research papers about treating enamel discoloration caused by hypomineralization with the ICON system can be accepted as satisfactory. However, not all cases achieved the full aesthetic aim. Microabrasion is an acid abrasive removal and not the dissolution of enamel stain. It is as a treatment modality for enamel opacities like brown, orange, or yellow enamel spots; and fluorotic white streaks. Esthetic results could be reached when microabrasion followed by a remineralizing agent such as C PP-ACFP. Null hypothesis, there is no difference between microabrasion followed by a remineralizing agent and resin infiltration treatment regarding clinical effectiveness \& patient satisfaction.

Inclusion Criteria: * ▪ Participants free from any systemic disease aged from 7 years to 12 years * Anterior permanent teeth with Degree 1(mild) hypomineralization (according to the Wetzel and Reckel scale) (as shown in Appenxix I). * Enamel opacities, (White, creamy or yellow to brownish colour), without enamel breakdown * Caries-free teeth. * Sensitivity to external stimuli e.g., air/water but not brushing. Exclusion Criteria: * ▪ Dental caries and filling, * Loss of the enamel or dentin structure, * Clinical symptoms of irreversible pulpitis such as spontaneous pain or persisting pain, * Previous use of bleaching agent. * Dental anomaly on anterior teeth, * Periodontal diseases, * Undergoing orthodontic treatment, * Cognitive and behavioral conditions. * Patients with milk protein or hydroxybenzoates allergies.
