Investigation of Clinical Characteristics and Etiological Factors in Children with Molar Incisor Hypomineralization

Abstract

Aim The purpose of the present study was to evaluate the clinical defects and etiological factors potentially involved in the onset of MIH in a pediatric sample. Methods 120 children, selected from the university dental clinic, were included: 60 children (25 boys and 35 girls; average age: 9.8 ± 1.8 years) with MIH formed the test group and 60 children (27 boys and 33 girls; average age: 10.1 ± 2 years) without MIH constituted the control group. Distribution and severity of MIH defects were evaluated, and a questionnaire was used to investigate the etiological variables; chi-square, univariate, and multivariate statistical tests were performed (significance level set at p < 0.05). Results A total of 186 molars and 98 incisors exhibited MIH defects: 55 molars and 75 incisors showed mild defects, 91 molars and 20 incisors had moderate lesions, and 40 molars and 3 incisors showed severe lesions. Univariate and multivariate statistical analysis showed a significant association (p < 0.05) between MIH and ear, nose, and throat (ENT) disorders and the antibiotics used during pregnancy (0.019). Conclusions Moderate defects were more frequent in the molars, while mild lesions were more frequent in the incisors. Antibiotics used during pregnancy and ENT may be directly involved in the etiology of MIH in children.

Prevalence of Hypersensitivity in Teeth Affected by Molar-Incisor Hypomineralization (MIH)

“…Besides that, MIH-affected patients present other several clinical problems such as esthetic complains, loss of fillings, need of reinterventions, an increased risk of dental caries, and dental hypersensitivity [Giuca et al, 2018].…”

Frequency of Molar Incisor Hypomineraliazation and Associated Risk Factors - A Study from Southern Punjab, Pakistan

“…Some of theseinclude low birth weight, chicken pox, hypocalcaemia, oxygenation issues, and fever in early childhood. 3 However, many studies in literature could not find significant relation between these factors and the disorder. Yet a study conducted in Brazil 5 found that oxygenation at birth, pneumonia, asthma, bronchitis, hospitalization and use of antibiotics had significant relation with molar incisor hypomineralization.…”

“…It was firstly named as molar incisor hypomineralization in 2001, suggested by Weerheijm et al 1 Molar incisor hypomineralization is defined as a developmental disorder that involves at least one permanent first molar by opacities that are not symmetrical. [2][3][4][5] The prevalence of molar incisor hypomineralization varies in different regions of the World and it was found in literature that lowest frequency of molar incisor hypomineralization is in Chinese population. 6 Studies conducted in Germany, Spain, Iran, Brazil and Iraq 7 found prevalence of molar incisor hypomineralization between 10.15 to 21.8%.…”

Evaluación del manejo terapéutico en estudiantes de pregrado, egresados y docentes en piezas con hipomineralización incisivo-molar (HIM) en una universidad privada de Lima

“…Sin embargo, a pesar de que existe una clasificación y criterios diagnósticos para el HIM, un gran número de odontólogos confunde el diagnóstico diferencial entre la alteración del esmalte versus lesiones cariosas [10][11][12][13] . Esto a su vez, genera un inadecuado plan de tratamiento, el cual conlleva al fracaso de la restauración debido a un diagnóstico equivocado [14][15] De igual manera, es importante resaltar las dificultades a las que se enfrenta el odontólogo al realizar el tratamiento en la pieza 16 . Entre estas se encuentran: manejar la conducta del niño, realizar un Odontol Pediatr Vol 14 Nº 2 Julio -Diciembre 2015 adecuado nivel de anestesia, elegir un buen diseño de preparación cavitaria y seleccionar apropiadamente los materiales de restauración [17][18] .…”
