“…In 2018, only 8-year-old children were included [22], while in the present study children between 6 and 12 years-old were examined. Previous studies have noted that MIH tend to worsen with age, as the demarcated opacities may progress to PEB over time [7,[23][24][25]. The association between age and MIH severity was also found in our study, with the most severe forms of MIH being more prevalent among older children.…”

“…At this severity level, children require preventive approach, mostly clinical monitoring, uorides, and sealants [12]. Monitoring might be enough for white opacities that are at lower risk of breakdown, while extra protective care might be necessary for yellow opacities that are at higher risk of breakdown [7]. However, when dealing with anterior teeth, patient's expectations and selfperception about teeth appearance are mandatory in terms of indication for aesthetic treatment.…”

“…Yellow-brownish opacities have a higher protein content and decreased mechanical properties than the white-creamy ones [6]. Therefore, darker opacities are at higher risk of breakdown and progression to the more severe levels of the condition [7]. MIH has been associated with higher caries prevalence and increased caries index in children [8,9].…”

Aim Assess the prevalence and severity of molar incisor hypomineralization (MIH) in children 6- to 12-year-old and correlate MIH severity with the complexity of treatment demands.Materials and methods Between March and October 2023, 2,136 children were screened for MIH by two calibrated examiners. MIH severity was categorized in mild, moderate, severe, and very severe. Treatment requirements were categorized in basic, intermediate, and complex.Results The prevalence of MIH was 15.5% (n = 331). Among the 126 children with atypical caries/restoration, cusp involvement was observed in 60.3%, endodontic treatment was necessary in 24.6%, only 15% needed restorations limited to two tooth surfaces with no cusp involvement. Extraction due to MIH was observed in 2.7%.Conclusion The prevalence of MIH was in accordance with previous literature. Whenever a restorative treatment was necessary, it often involved multiple tooth surfaces and cusps. The complexity of treatment demands increased with age. It is necessary that oral health policymakers pay special attention to children with MIH to ensure appropriate treatment.

“…Individuals with MIH experience clinical conditions that have a direct impact on their oral health and quality of life [2,[7][8][9][10]. The qualitative defect in this dental enamel is noted during mineralization, resulting in the enamel of softened consistency that easily fractures under chewing forces, starting from its eruption in the oral cavity [19,30]. This leads to dentin hypersensitivity [2,[11][12][13], caries [31,32],…”

Objectives This study aimed to assess unilateral molar-incisor hypomineralization (MIH) on the stomatognathic system in children, investigating if greater impairment exists on the affected side in terms of postural and masticatory activities and occlusal force contacts. Materials and Methods Fourteen children with unilateral MIH (mean age: 7.92 years) were included in this cross-sectional split-mouth observational study. Electromyography (EMG) evaluated masseter and temporal muscle activity during various jaw postures and habitual chewing. Occlusal force contacts were measured using T-SCAN®. The analyses compared the side with MIH to the side without the defect. Statistical analysis employed the Shapiro-Wilk test, Wilcoxon signed-rank test, and paired t-test. Results Muscle hyperactivity was observed on the unaffected side, indicating greater voluntary contraction compared to the affected side for the temporal muscle at rest (p = 0.01) and masseter muscle in right laterality (p = 0.02). No significant difference was found in occlusal force between the sides analyzed. Conclusions Children with MIH exhibit compromised stomatognathic system functionality, with enamel defects potentially disrupting balance and leading to functional limitations. Clinical Relevance: Children with unilateral MIH may present muscle hyperactivity on the unaffected side, suggesting enamel defects could lead to stomatognathic system imbalances with clinical implications for dentists.

“…On the other hand, the yellow opacity could be suggested as a step forward in the severity scale, being more porous than the white ones, with worse prism organization and more prone to acid attacks ( 23 ). This way, yellow areas may resemble a stricter stage involving post-eruptive enamel breakdowns and dental caries ( 24 ). Notably, niche retentiveness is important for LB accumulation ( 25 ).…”

Background Teeth with defects in their structure, such as the ones affected by molar-incisor hypomineralization (MIH), are more susceptible to carious lesions. Caries is a complex and multifactorial disease highly prevalent in childhood. The present research evaluated the relationship between the stages of MIH and cariogenic bacteria in children. Methods After examining 566 schoolchildren, four groups of 10 children each were formed: healthy (G1), mild MIH (G2 and G3), and severe MIH + caries (G4). Dental biofilm was assessed to quantify Streptococcus mutans (SM) and Lactobacillus spp. (LB) using real-time polymerase chain reaction (RT-PCR). Results LB counting in biofilm samples of healthy children (G1) and those with mild MIH characterized by white opacities (G2) were not significantly different. The same happened when the ones with yellow opacities (G3) were compared with severe MIH + caries (G4) (P>0.05). The post hoc Tukey test proved that G4 had greater levels of SM and LB when compared with G2 (P<0.05); however, the control group did not diverge from the others considering SM (P>0.05). Increased LB enhanced the severity of MIH [rate ratio (RR): 7.706; P=0.035]. Conclusions LB was influenced by different degrees of MIH and the presence of caries and could guide clinical decisions and patients’ recommendations to prevent carious lesions in MIH children.
