Impact of molar-incisor hypomineralization on oral health-related quality of life in schoolchildren

Abstract

This study evaluated the impact of molar-incisor hypomineralization (MIH) on oral health-related quality of life (OHRQoL) according to the perceptions of schoolchildren and their parents/caregivers. This cross-sectional study consisted of a sample of 594 schoolchildren between 11 and 14 years of age and their parents/caregivers who answered the questionnaires CPQ11-14ISF:16 and P-CPQ, respectively. The main independent variable of this study was MIH of the schoolchildren. Experience of dental caries, malocclusion, and socioeconomic status were treated as confounding variables. Statistical analysis used descriptive analysis and Poisson regression with robust variance. The prevalence of MIH was 18.9%. The overall P-CPQ score ranged from 0 to 35 (average = 7.26 ± 6.84), and the overall CPQ11-14ISF:16 score ranged from 0 to 47 (average = 11.92 ± 7.98). Severe MIH was associated with a greater negative impact of the "functional limitation" domain (RR = 1.41; 95%CI = 1.01-1.97), according to parents'/caregivers' perceptions. Severe MIH was associated with a greater negative impact of the "oral symptom" domain (RR = 1.30; 95%CI = 1.06-1.60) and functional limitation domain (RR = 1.42; 95%CI = 1.08-1.86), according to the schoolchildren's perceptions. Schoolchildren with severe MIH had a greater negative impact on the oral symptom and functional limitation domains than those without MIH. According to parents'/caregivers' perceptions, schoolchildren with severe MIH had a greater negative impact on the functional limitation domain than those without MIH.

Impact of molar incisor hypomineralization on quality of life in children with early mixed dentition: A hierarchical approach

“…An association was found between severe MIH and OHRQoL in the functional limitations domain of the CPQ 11‐14 , which addresses difficulties with chewing, sleep, and speech . In the previous study, a higher prevalence of more severe MIH lesions was observed (50.5%), which was different from the present results, in which these changes were uncommon (28.4%). The loss of dental structure increases the accumulation of biofilm and facilitates the transport of bacteria to dentin, thus aggravating sensitivity because there is greater exposure of dentinal tubules .…”

“…The impact of MIH on OHRQoL was previously evaluated in 11‐ to 14‐year‐old Brazilian children using the CPQ 11‐14 , which is specific to this age group. The authors who applied the CPQ 11‐14 also observed an impact of MIH in the oral symptoms domain but only in individuals with severe lesions, such as post‐eruptive fractures . An association was found between severe MIH and OHRQoL in the functional limitations domain of the CPQ 11‐14 , which addresses difficulties with chewing, sleep, and speech .…”

“…A greater impact of severe MIH lesions was found in the “oral symptoms” domain, which includes spontaneous or induced pain reports, bad breath, and food impaction, and in the “functional limitations” domain, which includes difficulties in chewing food and sleep disturbances. These findings derived from relatively older children who have a higher prevalence of severe MIH injuries, such as post‐eruptive fractures and atypical restorations . Molar incisor hypomineralization presents high clinical variability that is influenced by age .…”

Differential diagnoses of enamel hypomineralisation in an archaeological context: A postmedieval skeletal collection reassessment

“…Nowadays, the MIH global prevalence varies, mean 13.1% (Schwendicke et al, ), and damage caused to functionally essential teeth makes it a major public health problem (Schneider & Silva, ). MIH may impact on the well‐being of young patients in a crucial period of infant development (Dantas‐Neta et al, ; Leal, Oliveira, & Ribeiro, ). Moreover, currently, in the absence of identified cause(s), no risk prevention actions can be implemented (Silva, Scurrah, Craig, Manton, & Kilpatrick, ).…”

Analytical evidence of enamel hypomineralisation on permanent and primary molars amongst past populations

“…MIH constitutes a public health problem, with consequences that are not only health-related but also economic. MIH may impact on the well-being of young patients in a crucial period of infant development 15, 16 . The proposal for a single term “MIH” and the establishment of specific diagnosis criteria by consensus promoted and encouraged the multiplication and quality of research works, but some issues remain unresolved 11 .…”
