“…With respect to our results, for the entire sample, a prevalence of 16% of MIH was found, which is similar to what has been recently described in the literature [Schwendicke et al, 2018]. The subgroup analysis showed that the majority of teeth affected by MIH presented only opacities, followed by posteruptive breakdown involving dentin, and last involving only enamel.…”

Aim: This study aimed to investigate the prevalence of hypersensitivity in molar-incisor hypomineralization (MIH)-affected molars through a census carried out in 8-year-old schoolchildren. Methods: Examinations were conducted by a calibrated examiner, using the Nyvad criteria for caries diagnosis and a new criterion for MIH assessment. For hypersensitivity assessment, all MIH-affected molars were included. Nonaffected molars from the same child were used as controls. Air blast reaction was measured using the Visual Analogue Scale (VAS) and the Schiff Cold Air Sensitivity Scale (SCASS) scale, while tactile hypersensitivity was scored using VAS only. Statistical analysis was performed using the Kruskal-Wallis test followed by Dunn’s multiple comparisons test for quantitative data. χ² was used for the comparison of categorical data. Results: In total, 631 children were assessed, of whom 102 had MIH-affected molars (16.1%). Of these, 51.7 and 8.7% presented enamel and dentin carious lesions, respectively. Regarding the number of teeth, 239 molars were MIH affected (59.8%), with 188 (78.7%) being classified as mild (opacities only), 20 (8.4%) as moderate (posteruptive enamel breakdown), and 31 (13%) as severe (posteruptive breakdown involving dentin/atypical restorations). Hypersensitivity was recorded in only one control molar, while the prevalence of hypersensitivity in MIH-affected molars was 34.7%, being of low intensity and more prevalent in moderate (55%) and severe cases (51.6 %) than in mild cases (29.8%, p = 0.008). An association between hypersensitivity and the presence of mild and moderate cases was observed. Although the same association was observed for severe cases, it was not considered a reliable information as 90% of the MIH-affected molars with posteruptive breakdown involving dentin were affected by carious lesions. It is known that dental caries is a confounding factor for the presence of hypersensitivity. Conclusions: Hypersensitivity was significantly higher in MIH-affected molars than in nonaffected molars, being associated with MIH teeth presenting opacities and posteruptive enamel breakdown.

“…In total, 78 consecutive patients suffering from at least one hypomineralized tooth were selected among the patient pool. The guidelines of the European Academy of Pediatric Dentistry (Lygidakis et al, ; Schwendicke et al, ; Weerheijm, ; Weerheijm et al, ) were applied to diagnose the MIH‐positive teeth: (a) clearly definable opacity and/or buccal surfaces of the crowns, (b) white‐/yellow‐to‐brown discolorations, (c) MIH defects of at least 1 mm in diameter, (d) the presence of hypersensitivity, (e) the presence of atypical restorations, and (f) the extraction of permanent teeth due to MIH. Patients who did not collaborate willingly were excluded from the survey.…”

Objective The aim of this clinical follow‐up study was to demonstrate the effects of different therapeutic strategies for hypomineralized teeth on patients' oral health. The treatment results were characterized by changes in the extent of hypersensitivity and plaque accumulation, as well as reductions in nutritional restrictions. Material and Methods The impacts of therapy, including the use of fluoride varnish, fissure sealants, fillings, and stainless steel crowns, were evaluated in 78 children (mean age 8.5 years). We followed recommendations according to the Molar Incisor Hypomineralisation Treatment Need Index for customized treatment. The Quigley Hein Index, the Schiff Cold Air Sensitivity Scale, Wong–Baker Faces Scale, and dietary‐limiting parameters were assessed before and after therapy for comparison. Results Plaque accumulation and hypersensitivity decreased after completion of therapy. The improvements were greater for individual teeth (Quigley Hein Index for teeth treated with stainless steel crowns from 4.19 to 2.54) than for those of the whole dentition (high‐severity category from 2.67 to 2.20). Problems with food intake were minimized via therapy, with the greatest influence observed for patients who were also in the high‐severity category. Conclusions Therapy for affected teeth in children has positive effects on oral health and quality of life.

“…Some authors have suggested a genetic‐based etiology . The prevalence of MIH in children and adolescents varies among different studies, with reported values between 2.8% and 40% . Clinically, MIH is characterized by variable‐sized opacities, with a white to yellow/brownish staining and a defined demarcation between healthy and affected enamel .…”

Introduction Defects in the maturation stage of amelogenesis result in a normal volume of enamel but insufficient mineralization, called hypomineralization. Molar‐incisor hypomineralization (MIH), amelogenesis imperfecta and dental fluorosis (DF) are examples of such defects. Objective To evaluate the effectiveness of the treatments applied to the different forms of dental hypomineralization. Materials and Methods PubMed, Scopus, Cochrane Library, Web of Science, and Embase were screened. The research was limited to studies published in English, Spanish, and Portuguese, until May 30, 2018. The research question was formulated following the Population, Intervention, Comparison, Outcome strategy. The quality of the methodology of each article was evaluated employing the Cochrane Handbook for Systematic Reviews. Results From the initial research, 7895 references were obtained, of which 33 were included in the systematic review. The following treatments were reported: desensitizing and remineralizing products, resin infiltration, restorations, fissure sealants, tooth bleaching, enamel microabrasion and calcium, and vitamins supplements. Conclusions Although the results are suggestive, there is a clear need for a greater uniformity of the methodologies, thus allowing for the development of clinical guidelines. Nevertheless, it was possible to identify several effective treatments for teeth with MIH (arginine pastes or fluoride varnishes) and DF (tooth bleaching and/or enamel microabrasion). Clinical Significance Because MIH, amelogenesis imperfecta, and DF are commonly seen in dental daily practice, it is extremely important to analyze the literature regarding its treatment.
