Influence of customized therapy for molar incisor hypomineralization on children's oral hygiene and quality of life.

OBJECTIVE: The aim of this clinical follow-up study was to demonstrate the effects of different therapeutic strategies for hypomineralized teeth on patients' oral health. The treatment results were characterized by changes in the extent of hypersensitivity and plaque accumulation, as well as reductions in nutritional restrictions. MATERIAL AND METHODS: The impacts of therapy, including the use of fluoride varnish, fissure sealants, fillings, and stainless steel crowns, were evaluated in 78 children (mean age 8.5 years). We followed recommendations according to the Molar Incisor Hypomineralisation Treatment Need Index for customized treatment. The Quigley Hein Index, the Schiff Cold Air Sensitivity Scale, Wong-Baker Faces Scale, and dietary-limiting parameters were assessed before and after therapy for comparison. RESULTS: Plaque accumulation and hypersensitivity decreased after completion of therapy. The improvements were greater for individual teeth (Quigley Hein Index for teeth treated with stainless steel crowns from 4.19 to 2.54) than for those of the whole dentition (high-severity category from 2.67 to 2.20). Problems with food intake were minimized via therapy, with the greatest influence observed for patients who were also in the high-severity category. CONCLUSIONS: Therapy for affected teeth in children has positive effects on oral health and quality of life.
