Molar incisor hypomineralization: prevalence, severity and clinical consequences in Brazilian children

Abstract

Despite the high prevalence of MIH, the severity of the defects was mild. The results indicate a positive association between MIH and the presence of dental caries.

Possible Medical Aetiological Factors and Characteristics of Molar Incisor Hypomineralisation in a Group of Turkish Children

“…On je stupnjeve MIH-a klasificirao kao: -blage (ograničeni opaciteti bez potrebe za terapijom), -umjerene (lezije na zubima s grubom i slomljenom caklinom), -teške (hipomineralizirane lezije povezane s gubitkom caklinske i dentinske strukture; atipične restauracije koje zamjenjuju zahvaćeno tvrdo zubno tkivo; ekstrakcija zuba zbog teške demineralizacije) (11). Kod svakog djeteta hipomineralizacija je procijenjena ovisno o najvišem uočenom stupnju na prvom trajnom kutnjaku ili na trajnim sjekutićima.…”

“…The severity of MIH was classified as mild (demarcated opacities with no need for treatment), moderate (lesions in teeth with rough and broken enamel), or severe (hypomineralised lesions associated with the loss of enamel and dentine structure; atypical restorations replacing affected hard tissue; extraction of teeth because of severe hypomineralisation) (11 …”

Molar Incisor Hypomineralization: Morphological, Aetiological, Epidemiological and Clinical Considerations

“…In a Brazilian survey, children with MIH showed higher caries experience in the permanent dentition than the general population of similar age. (da Costa-Silva et al, 2010) The MIH increases the dental caries risk as consequence of affected teeth because they are not only soft and porous enamel teeth but also very sensitive to stimuli making effective oral hygiene difficult. (Kilpatrick, 2009) Several aetiological factors are mentioned as the cause of MIH (Alaluusua, 2010, Crombie et al, 2009, Brook, 2009 and they are frequently associated with childhood diseases or nutritional conditions during the first three years of life.…”

Definition and scoring system of molar incisor hypomineralization: A review

“…For example, Fteita et al [22], Laisi et al [23], and da Cost-Silva et al [24] classified their cases into mild, moderate, or severe according to the degree of tooth structure loss. Lygidakis et al [25] and Kevrekidou et al [20] suggested that it's better to classify MIH cases into two groups only (mild and severe) combining the previously designed two categories of moderate and severe into one group.…”

“…To a great extent, the lack of standardization and heterogeneity of the scoring or characterization systems used in each study probably contributed to the variability. Although a few studies used the current EAPD characterizing system (Table 3), some authors have either used some modifications or created their own scoring system which makes it obvious that there is a certain degree of confusion and lack of consensus [3,[22][23][24][25][26]. The usefulness of the early EAPD criteria should also be reevaluated due to the fact that it only categorizes the enamel conditions but does not quantify them.…”
