Inclusion criteria
Inclusion criteria: The general health condition is good, and the age is between 6 and 14 years old. The MIH and DH reports of at least one tooth are located in the neck, and the VAS sensitivity is equal to or greater than 4. The criteria put forward by the European Society of Pediatric Dentistry were applied to diagnose molar-incisor dysmineralization (MIH): (a) The enamel of one to four permanent first molars was hypomineralized, with or without affected permanent incisors. (b) clearly identifiable crown opacity and/or buccal surface, (c) white, cream or yellow to light brown discoloration, (showing white, yellow or brown boundary opacity), (d) MIH defect with a diameter of at least 1 mm, and loss of enamel structure after eruption. (e) there are allergies, and the sensitive affected teeth range from mild reaction to external stimuli to spontaneous allergies, (f) there are atypical restorations, and (g) permanent tooth extraction due to MIH.
Exclusion criteria
Exclusion criteria: 1. Active dental caries or restoration defects of the selected teeth or adjacent teeth; 2. Active periodontal disease on the selected teeth and gingival recession exceeding 3 mm; 3. Currently receiving orthodontic treatment; 4. Have cognitive or behavioral problems; 5. Sufficient dentin loss requiring restorative treatment or periodontal surgery; 6. Have received any professional desensitization treatment in the past 6 months; 7. Used desensitizing cream in the past 3 months; 8. Use analgesic/anti-inflammatory drugs during the study; 9. Enamel defects other than 9.MIH, such as dental fluorosis, enamel hypoplasia, enamel hypoplasia, dentin hypoplasia, tetracycline staining and tooth erosion; 10. Have any systemic diseases.
