Impact of Molar Incisor Hypomineralisation on Quality of Life.

Abstract

Oral health-related quality of life (OHRQoL) is a multifaceted concept that surpasses an exclusively clinical perception and includes functional, social, emotional, and environmental issues. The measure of OHRQoL represents a holistic approach for research and clinical practice. Negative impacts of oral conditions on OHRQoL in childhood can reflect on health development, especially in a life stage marked by social and cognitive maturation. Therefore, such problems can impact negatively on the daily lives of the individuals and their families. Individuals with molar incisor hypomineralisation (MIH) experience more frequent posteruptive breakdown, an elevated risk of tooth decay, filling failures, the need for recurrent dental treatment, and a higher prevalence of dental hypersensitivity. Children with severe MIH may struggle with everyday activities, such as brushing their teeth, speaking, smiling, chewing, and consuming hot or cold foods. MIH-affected incisors may exhibit opacities that can impact the aesthetics of their smiles. This condition may discourage children from smiling and can indirectly affect their parents as well. The management modalities are focused on solving functional, aesthetic, and hypersensitivity problems and to evaluate OHRQoL values before and after therapies. Therefore, this chapter aims to discuss how MIH affects the OHRQoL of children and the questionnaires that can be used to evaluate that impact.
