Abstract
OBJECTIVES This study aimed to assess the clinical performance outcome at 36 months of molars with molar incisor hypomineralization and carious lesions, treated with two different restorative approaches following selective caries removal. METHODS The children aged 6 to 12 years (18 female, 13 male) included in the study had at least two carious permanent first molars diagnosed with molar incisor hypomineralization. Sixty-two molars were restored in a split-mouth design. In all subjects, selective caries removal was performed so that caries was completely removed from the cavosurface walls and only soft dentin was left above the pulp chamber. Short fiber reinforced composite (SFRC; EverX Flow™) covered by micro-hybrid composite (G-Aenial® posterior composite) and Glass Hybrid (GH; Equia Forte® HT) were used as restorative materials. The restorations were evaluated according to modified United States Public Health Service (USPHS) criteria at baseline, 6, 12, 18, 24, and 36 month follow-ups. RESULTS During the 36-month follow-up, eight GH and four SFRC restorations failed. The clinical success of both restorations decreased statistically over time (p < 0.001 for both). When variables such as restoration type, sex, age, tooth type, and time were included in the model, the risk of failure of the restorations of the left lower first molar was statistically significantly higher than that of the left upper first molar (p < 0.002). CONCLUSION Direct composite restorations with SFRC and GH restorations perform similar clinical success with selective caries removal in the management of permanent molars affected by molar incisor hypomineralization. CLINICAL SIGNIFICANCE SFRC or GH restorations with similar clinical success might be preferred for the management of MIH-affected molars.

Abstract
OBJECTIVES The study aimed to evaluate the impact of molar incisor hypomineralization (MIH) and tooth sensitivity on the oral health in terms of the quality of life (OHRQoL). In addition, the impact of tooth maturity on tooth sensitivity was evaluated in the study. MATERIALS AND METHODS Children aged 8-12 years with and without MIH participated in this descriptive cross-sectional study. They were chosen through the convenience sample technique. The Pediatric-Oral-Health-related-Quality-of-Life (POQL) scale was used to assess OHRQoL. The presence of the MIH and decayed, filled and missing teeth due to caries (using dmft/s, DMFT/S indexes) were recorded. The tooth sensitivity and dental maturity status were evaluated with the Shiff-Cold-Air-Sensitivity-Scale (SCASS) and Demirjian-method, respectively. Statistical analysis of the data was performed by Pearson Chi-Square Test and Mann-Whitney U test (p<0.05). RESULTS In this study, the participants were a total of 260 children, half were affected by the MIH. Their mean POQL scores were higher than those of the children without MIH with a statistically significantly difference in the total child scale score (p=0.014). Among the children with the MIH, child total QoL score was found to be higher in SCASS positive response group (p=0.011). The teeth with MIH (p<0.001) showed higher response to the stimulus. According to the dental age and dental maturity categories of the children with MIH, the total child scale score was found to be higher in the SCASS category (p=0.011), and the response status to the SCASS was statistically significant (p=0.042 and p=0.05, respectively). CONCLUSIONS Among the children with MIH, the OHRQoL was found to be negatively affected. The teeth with the MIH tend to reveal more tooth sensitivity than healthy teeth. Many conditions such as having MIH, and tooth sensitivity might have an impact on the OHRQoL. In addition, more sensitivity to the stimulus was observed in the teeth with lower tooth maturity status; the dental age and dental maturity might have effects on tooth sensitivity. CLINICAL RELEVANCE Considering the negative impacts due to MIH, the evaluation of OHRQoL is critical for dentists to employ a well-defined guide in their clinical decisions.

Abstract
PURPOSE This questionnaire aimed to explore how general dentists in the Republic of Ireland perceive and manage hypomineralised second primary molars (HSPM). METHODS Following ethical approval, a validated structured questionnaire containing 19 questions was sent to Irish dentists using Survey Monkey. Questions on awareness, dentist's experience, barriers to care and clinical scenarios with different treatment options were included. Binary outcomes and independent variables were compared using logistic regression analysis (α = 5%). RESULTS Responses from 279 general dentists were analysed. The majority of dentists were aware of HSPM (72%) and most dentists felt confident in diagnosing HSPM (71%). Dentists who had practiced for ≥ 15 years were significantly more likely to document HSPM frequently compared to those with less experience (OR 0.29; p = 0.012). No significant association was found between confidence in HSPM diagnosis and other variables, such as age group, years of practice and workplace. Dentists not working in private practice reported to be less comfortable in the management of HSPM (OR 0.49; p = 0.030). The most cited barrier to management of HSPM was child's behaviour. A broad variation was observed in the clinical scenarios, in particular when treatment planning more severe HSPM. CONCLUSIONS In general, Irish dentists are aware of HSPM and are confident in diagnosis and management. Variation existed in treatment options reflecting the disparity that exists in clinical management.

Abstract
An in-depth study of the Early Pleistocene European remains of Hippopotamus has allowed the first detailed description of the incidence and types of dental alterations related to palaeopathologies and potentially linked to climatic and environmental factors. The results of a long-term qualitative and quantitative assessment highlight the importance of nutrient deficiencies on the development of dental enamel hypoplasia in Hippopotamus. Glacial cyclicity and the resulting changes in humidity and plant community structure conditioned the local environments critical for the survival of this taxon. Two main intervals of putative constrained nutritionally restrictions were detected at ca. 1.8 Ma and ca. 0.86 Ma (i.e., MIS63 and MIS21, respectively). Statistical comparisons show an increase in the frequency of dental hypoplasia between these two chronological periods, thus reinforcing the idea of increased seasonality in the circum-Mediterranean environments during the Early Pleistocene.

Abstract
Many geographical areas of the world are polluted by both fluoride and sulfur dioxide (SO2). However, the effects of simultaneous exposure to fluoride and SO2 on teeth are unknown. Fibroblast growth factor-9 (FGF9) and transforming growth factor-β1 (TGF-β1) are key signaling molecules in enamel development. The purpose of the study was to explore the effects of co-exposure to fluoride and sulfur dioxide on enamel and to investigate the role and mechanism of FGF9 and TGF-β1. First, sodium fluoride (NaF) and SO2 derivatives were used to construct rat models and evaluate the enamel development of rats. Then, TGF-β1 (cytokine) treatment, SIS3 (inhibitor) treatment and FGF9 gene knockdown were used to explore the mechanism of enamel damage in vitro. The results showed that enamel column crystals in the exposed group were characterized by enamel hypoplasia, as indicated by alterations such as disarrangement of enamel column crystals, space widening and breakage. Ameloblasts also showed pathological changes such as ribosome loss, mitochondrial swelling, nuclear fragmentation and chromatin aggregation. The protein expression of FGF9 was higher and the protein expression of AMBN, TGF-β1 and p-Smad2/3 protein was lower in the groups treated with fluoride and SO2 individually or in combination compared with the control group. Further studies showed that TGF-β1 significantly upregulated p-Smad2/3 and AMBN protein expression and reduced the inhibitory effects of fluoride and SO2; furthermore, SISI blocked the effect of TGF-β1. In addition, knockdown of FGF9 upregulated TGF-β1 protein expression, further activated Smad2/3 phosphorylation, eliminated the inhibitory effects of fluoride and SO2, and increased the protein expression of AMBN. In brief, the study confirms that co-exposure to fluoride and SO2 can result in enamel hypoplasia in rats and indicates that the underlying mechanism may be closely related to the effect of FGF9 on enamel matrix protein secretion through inhibition of the TGF-β1/Smad signaling pathway.

Abstract
Spondylocarpotarsal synostosis (SCT) syndrome is a very rare and severe form of skeletal dysplasia. The hallmark features of SCT are disproportionate short stature, scoliosis, fusion of carpal and tarsal bones, and clubfoot. Other common manifestations are cleft palate, conductive and sensorineural hearing loss, joint stiffness, and dental enamel hypoplasia. Homozygous variants in FLNB are known to cause SCT. This study was aimed to investigate the phenotypic and genetic basis of unique presentation of SCT syndrome segregating in a consanguineous Pakistani family. Three of the four affected siblings evaluated had severe short stature, short trunk, short neck, kyphoscoliosis, pectus carinatum, and winged scapula. The subjects had difficulty in walking and gait problems and complained of knee pain and backache. Roentgenographic examination of the eldest patient revealed gross anomalies in the axial skeleton including thoracolumbar and cervical fusion of ribs, severe kyphoscoliosis, thoracic and lumbar lordosis, coxa valga, fusion of certain carpals and tarsals, and clinodactyly. The patients had normal faces and lacked other typical features of SCT like cleft palate, conductive and sensorineural hearing loss, joint stiffness, and dental enamel hypoplasia. Whole exome sequencing (WES) of two affected siblings led to the discovery of a rare stop-gain variant c.220C>T (p.(Gln74*)) in exon 1 of the FLNB gene. The variant was homozygous and segregated with the malformation in this family. This study reports extensive phenotypic variability in SCT and expands the mutation spectrum of FLNB.

Abstract
Amelogenesis imperfecta (AI) is one of the typical dental genetic diseases in human. It can occur isolatedly or as part of a syndrome. Previous reports have mainly clarified the types and mechanisms of nonsyndromic AI. This review aimed to compare the phenotypic differences among the hereditary enamel defects with or without syndromes and their underlying pathogenic genes. We searched the articles in PubMed with different strategies or keywords including but not limited to amelogenesis imperfecta, enamel defects, hypoplastic/hypomaturation/hypocalcified, syndrome, or specific syndrome name. The articles with detailed clinical information about the enamel and other phenotypes and clear genetic background were used for the analysis. We totally summarized and compared enamel phenotypes of 18 nonsyndromic AI with 17 causative genes and 19 syndromic AI with 26 causative genes. According to the clinical features, radiographic or ultrastructural changes in enamel, the enamel defects were basically divided into hypoplastic and hypomineralized (hypomaturated and hypocalcified) and presented a higher heterogeneity which were closely related to the involved pathogenic genes, types of mutation, hereditary pattern, X chromosome inactivation, incomplete penetrance, and other mechanisms.The gene-specific enamel phenotypes could be an important indicator for diagnosing nonsyndromic and syndromic AI.

Abstract
AIM To explore the existing salivary, gingival crevicular fluid (GCF), blood, and serum biomarkers associated with grade C molar-incisor pattern (C/MIP) periodontitis in systemically healthy children and young adults. MATERIALS AND METHODS Cross-sectional, case-control, and cohort studies on stage III grade C periodontitis or former equivalent diagnosis with analysis of molecular biomarkers in saliva, GCF, blood, or serum were retrieved from six databases and screened based on the eligibility criteria. The risk of bias in included studies was evaluated. Meta-analysis was planned for biomarkers assessed using the same detection methods and sample type in at least two papers. RESULTS Out of 5621 studies identified at initial screening, 28 papers were included in the qualitative analysis of which 2 were eligible for meta-analysis for IgG in serum samples. Eighty-seven biomarkers were assessed with the majority being higher in cases than in controls. Only the meta-analysis of total serum IgG with low heterogeneity value revealed a significant increase in its levels in C/MIPs compared to controls (standardised mean difference: 1.08; 95% CI: 0.76, 1.40). CONCLUSION There is a paucity of data on biomarkers associated with molar-incisor pattern periodontitis. Although serum IgG levels are raised, other more specific biomarkers in saliva, GCF, and blood/serum may be promising but require further investigation.

Abstract
INTRODUCTION Molar-incisor hypomineralization (MIH) is a qualitative defect of dental enamel that affects one or more permanent first molars, with or without involvement of the incisor teeth. This condition leads to challenges to dental care and treatment planning. AIM Based on the hypothesis that children who have MIH possibly present alterations in postural and masticatory activities and considering the absence of studies investigating these parameters, the present study evaluated the functionality of the stomatognathic system considering the mentioned aspects. MATERIALS The comparison of individuals with (MIHG; n = 32) and without MIH (CG; n = 32) was evaluated by electromyographic activity of the masseter and temporal muscles (right and left), as well as evaluation of the masticatory cycles during habitual mastication. RESULTS MIHG showed muscle hyperactivity in postural and dynamic conditions compared to the CG; higher electromyographic values for MIHG when compared to CG in the following postural conditions: at rest for the right temporal (p = 0.00) and left temporal muscles (p = 0.03); in the protrusion to the right temporal muscle (p = 0.02); in the right laterality for the right masseter (p = 0.00) and left temporal muscles (p = 0.01); in the left laterality for the right masseter (p = 0.03) and left temporal (p = 0.04) muscles. In dynamic conditions with consistent food, significance was observed for the left temporal (p = 0.01); and with soft food for the right (p = 0.01) and left temporal muscles (p = 0.04). CONCLUSIONS Children with MIH seem to have impaired functionality of the stomatognathic system. Children with MIH have alterations in the stomatognathic system.

Abstract
OBJECTIVE To assess the impact of caries, Molar Incisor Hypomineralization (MIH), and fluorosis on the Oral Health-Related Quality of Life (OHRQoL) of schoolchildren aged 8-10 years living in area with different fluoride levels in the drinking water. SUBJECT AND METHODS The prevalence of caries and fluorosis were assessed among 663 Mexican schoolchildren using the International Caries Detection and Assessment System (ICDAS II) and the Thylstrup and Fejerskov Index (TFI), respectively. MIH was recorded using the European Academy of Pediatric Dentistry (EAPD) criteria and OHRQoL using the Child Perceptions Questionnaire (CPQ8-10). Poisson regression models were used in data analysis. RESULTS Schoolchildren presenting two of the three conditions (cavitated lesions and TFI≥4, cavitated lesions and MIH or TFI≥4 and MIH) experienced worse quality of life than children who did not [RR=4.18; (95% CI 3.83, 4.56)]. Children with all three conditions had worse quality of life than children who did not [RR=5.64; (95% CI 5.13, 6.20)]. CONCLUSIONS Fluorosis, MIH, and caries have a negative impact on the OHRQoL of schoolchildren living in area with a high concentration of fluoride in their drinking water.

Abstract
Teeth affected by molar incisor hypomineralization (MIH) present micromorphologic changes and hypersensitivity, which increase the risk of developing caries lesions and affect bonding procedures. Considering that practitioners still misdiagnose teeth affected by MIH, there is an urge for more knowledge about this topic in order to propose a more adequate and conservative treatment. The purpose of this study was to report the clinical challenges regarding the restorative management of a patient with MIH. A 13-year-old girl sought dental treatment, complaining about hypersensitivity in posterior teeth. Under clinical exams, notable enamel alterations mainly affecting posterior teeth (including molars) presented particular characteristics frequently attributed to MIH, and visible stains on maxillary central incisors were present. Because the mineral and organic content of MIH-affected enamel differ from sound enamel, it may imply special care for bonding of a restorative material. Thus, in order to promote a minimally invasive approach, selective removal of carious tissue and restoration with microhybrid composite resin was conducted after application of a universal bonding system used as self-etching strategy. After a 2-year follow-up, the restorations presented good clinical performance and the patient had limited hypersensitivity discomfort, suggesting a promising performance.

Abstract
Objectives We aimed to assess the association between molar incisor hypomineralization (MIH) and the oral health-related quality of life (OHRQoL) in a group of 7- to 14-year-old children in Berlin, Germany. Materials and methods The cross-sectional study consisted of a consecutive sample of 317 children, aged 7–14 years (49% girls, 51% boys; mean age, 8.71). Data were collected between June 2018 and December 2019. MIH was diagnosed using the criteria of the European Academy of Paediatric Dentistry. OHRQoL was assessed using the German 19-item version of the Child Oral Health Impact Profile (COHIP-G19). Differences in COHIP-19 summary scores between controls without MIH and MIH patients and with regards to MIH severity were tested for statistical significance using t test and analysis of variance (ANOVA), respectively. Results Data were obtained for 217 untreated MIH patients and 100 controls. OHRQoL of MIH patients was significantly more impaired than of controls indicated by COHIP-19 mean scores (60.9 ± 10.7 vs. 67.9 ± 7.8; p < 0.001). Patients with severe MIH (59.6 ± 11.0) reported significantly worse OHRQoL than patients with mild MIH (63.6 ± 9.1; p = 0.013). Conclusions MIH has a significant negative impact on the children’s OHRQoL. Patients with severe MIH experience a greater negative impact on OHRQoL than those diagnosed with mild MIH. Clinical significance MIH is one of the major dental problems of our time; pediatric dentists should be aware of its impact on the OHRQoL of the patient.

Abstract
PURPOSE Molar Incisor Hypomineralization (MIH) are first molars with developmental enamel defects and are common findings in many child populations. The porous nature of MIH enamel and the presence of post-eruptive enamel breakdown leads to the presence of hypersensitivity and pain, which is often the patient's main complaint and can result in dental fear and affect the quality of life. The present review aims to summarise the evidence for the ability of MIH to cause problems, such as dental fear and anxiety (DFA) and to summarise the evidence for a possibly negative impact on the oral health-related quality of life (OHRQoL) of MIH affected children and adolescents, in a systematic review. METHOD Two searches, (1) MIH AND dental anxiety and (2) MIH AND Quality of life, were performed in MEDLINE/PubMed and Scopus. Selection demands were fulfilling the MIH diagnosis criteria using validated instruments and questionnaires for assessing DFA and OHRQoL, respectively. RESULTS After removing duplicates and articles not fulfilling the selection demands, 6 studies concerning MIH and DFA and 8 studies concerning MIH and OHRQoL remained. CONCLUSION Children and adolescents with diagnosed MIH did not seem to suffer from increased dental fear and anxiety, but indicated an impaired oral health-related quality of life.

Abstract
Enamel Hypoplasia (EH) is known to be a useful indicator for wide range of detrimental factors in early childhood in past populations, such as nutritional disturbances, mechanical trauma, disease, metabolic, and/or genetic disorders. EH may be divided into three categories: pits, grooves, and lines, where the last two are referred to as "Linear Enamel Hypoplasia" (LEH). The regularity of enamel formation allows retrospective determination of the age of LEH formation. The current article reviews and compares the best-known methods used to estimate age at LEH formation and provides a new computational tool. Growth curves for canines and incisors were developed based on tooth growth tables by previous authors. Optimal models were selected using the Akaike Information Criterion. A Microsoft Excel spreadsheet was created to calculate age at LEH formation using the most common methods. All method results were compared with an archaeological sample (44 teeth of 18 individuals from an early modern cemetery from Wrocław, Poland) and a theoretical model. The results of the methods were compared pairwise with Bland-Altman plots. The current article provides a quick and easy-to-use tool for analyzing LEH chronology and comparing the results of different methods. As shown by the Bland-Altman plots, most methods provide approximately consistent results for LEHs formed at around 2-3 years of age. However, LEHs formed particularly early or late are more prone to discrepancies between different methods. Comparison of the age at LEH formation obtained by different methods should be done carefully - and the new LEH calculation tool with optimized equations provided in this publication can facilitate this process.

Abstract
OBJECTIVES To evaluate the factors that influences the kinetics of resin infiltration of molar incisor hypomineralisation (MIH) lesions on permanent anterior teeth. METHODS Demarcated MIH lesions with homogeneous and heterogeneous lesion body appearance, Types 1 (n = 14) and 2 (n = 18), respectively, were selected. After removal of the lesion surface layer using a tapered diamond finishing bur, the lesions were etched and ethanol was applied to the lesions and it was determined if the lesion was still visible or not. Images were taken just prior infiltrant (Icon; DMG) application (T0), during the infiltration process (Tx) and when infiltration had ceased progressing or opacity disappearance was clinically apparent (Tmax). Surface-area measurements of the opacity and infiltrated area were calculated and the infiltration proportion (IPx) was calculated over the infiltration time. RESULTS Type 1 and positive ethanol test lesions showed significantly lower mean Tmax (3.4 min) in comparison with Type 2 and negative ethanol test lesions (9.9 min) [Student t-test/Fisher's exact test; p < .01]. A non-linear correlation was observed (R2 = 0.88) indicating that the IPx was rapid at the beginning of resin application, decreasing over time. CONCLUSION In comparison with Type 1 and positive ethanol test lesions, Type 2 and negative ethanol test lesions require longer application time to infiltrate. CLINICAL SIGNIFICANCE MIH-lesion type and the 'ethanol test' were reliable predictive factors for the application time required for infiltrating MIH lesions on permanent anterior teeth.

Abstract
Pathogenic-activating variants of interferon induced with Helicase C domain 1 (IFIH1) cause Singleton-Merten (S-M) syndrome, which accompanies acro-osteolysis, loss of permanent teeth, and aortic calcification, as well as causing Aicardi-Goutières (A-G) syndrome, which shows progressive encephalopathy, spastic paraplegia, and calcification of basal ganglia. Recently, patients with overlapping syndromes presenting with features of S-M syndrome and A-G syndrome were reported. However, progression of clinical features of this condition has not been fully understood. We report a Japanese boy with a novel pathogenic IFIH1 variant who presented with clinical features of S-M syndrome and A-G syndrome.

Abstract
The aim of this study was to determine the frequency and severity of dental fluorosis (DF) and the association between severity and risk factors. In a cross-sectional study, 8- to 12-year-old children, born in a Colombian district, were evaluated according to the Thylstrup and Fejerskov Index (TFI) by two calibrated examiners. Molar Incisor Hypomineralization (MIH) and dental caries (DC) were also evaluated. Ordinal logistic regression was applied (p<0.05). Risk factors and lifestyle factors were collected using a questionnaire answered by parents. DF was detected in 76 (98.7%) of the children (average of 18.4 ±1.81 permanent teeth affected). Grade TF2 was the most frequently observed (34.8%); TF5 was observed in all age groups; TF6- TF7 were observed in 12-year-olds. No association was found between DF severity and DC (Odds Ratio (OR)=1.35; 95%CI: 0.56-3.26) or MIH (OR=1.39; 95%CI: 0.43-4.46). DF severity was significantly associated with use of an indoor wood stove for food preparation (OR = 9.34; 95%CI: 1.11-78.57) and use of a pea-sized volume of toothpaste (OR = 27.42; 95%CI: 1.57-477.36). Prevalence of DC was 38.1% and prevalence of MIH was 14.4%. In this population, the frequency of DF was high and severity was associated with use of an indoor wood stove for food preparation and toothpaste amount used during childhood.

Abstract
Purpose: The purposes of this study were to: (1) compare dental hypersensitivity (DH) between hypomineralized permanent first molars and unaffected controls molars in patients with molar-incisor hypomineralization (MIH); and (2) assess the influence of opacity, color, and subject age on DH. Methods: This cross-sectional study identified 40 children/adolescents, who were attending a children's dental clinic and had one to three first permanent molars hypomineralized (demarcated opacities). The severity and color of the hypomineralized lesions were also evaluated. The assessment of DH was made using evaporative stimulus using a jet of compressed air applied by a dental syringe for one second, perpendicular to the occlusal surface employing the visual analogue scale (VAS) and the Schiff cold air sensitivity scale (SCASS). To verify the association between the presence or absence of DH and MIH, Pearson's chi-square and Fisher's exact test (P<0.05) were performed. Results: The frequency of DH was 28.0 percent in hypomineralized teeth and 9.4 percent in normal controls (by VAS; P=0.002). A higher frequency of opacities was observed (P<0.001). Older individuals had DH more frequently (P<0.05). Conclusions: Hypomineralized molars presented a higher frequency of dental hypersensitivity than control teeth, and dental hypersensitivity was associated with darker opacities of the lesion and older-aged subjects.

Abstract
Purpose: This study's purpose was to investigate whether polymorphisms in the HIF-1 encoding gene and hypoxia-related environmental factors were associated with hypomineralized second primary molars (HSPMs). Methods: From a total of 731 children from Curitiba, Paraná, Brazil, were selected, the prevalence of HSPMs in this population was 9.4 percent, representing 69 cases (HSPMs) and 662 controls. The environmental factors were collected via questionnaire. HSPMs were evaluated by calibrated examiners. Two genetic polymorphisms (rs2301113 and rs2057482) in the HIF-1 gene were genotyped by polymerase chain reaction in real time. Associations were tested by Poisson regression analysis (Prevalence Ratioadjusted; P<0.05). Results: In the multiple variable model, including the environmental factors and genetic polymorphisms, maternal use of an illicit drug (Prevalence Ratioadjusted; equals 4.52; P<0.001; 95 percent confidence interval [95% CI] equals 2.38-8.53), maternal diseases during pregnancy (Prevalence Ratioadjusted; equals 1.97; P=0.034; 95% CI equals 1.05 to 3.71), and respiratory diseases during childhood (Prevalence Ratioadjusted; equals 2.66; P=0.003; 95% CI equals 1.41 to 5.03) increased significantly the prevalence of HSPMs. In the presence of environmental factors, individuals carrying at least one C allele in rs2057482 had a lower prevalence of HSPMs (Prevalence Ratioadjusted; equals 0.51; P=0.048; 95% CI equals 0.27 to 0.99). Conclusions: Children who had hypoxia-related factors presented with a higher prevalence of hypomineralized second primary molars. A C allele in rs2057482 served as protection against HSPMs in hypoxia conditions.

Abstract
PURPOSE Hypersensitivity is a frequent complaint in children with molar incisor hypomineralisation (MIH). This double-blind randomised controlled trial aimed to evaluate non-inferiority in hypersensitivity relief of a toothpaste containing microcrystalline hydroxyapatite compared to amine fluoride in children with MIH. MATERIALS AND METHODS Children were randomised into 2 groups: either hydroxyapatite (intervention) or amine fluoride toothpaste (control). The primary endpoint was pain sensation in response to tactile stimulus (Wong-Baker FACES Pain Rating Scale) 56 days after randomisation and analysed by mixed effects linear regression analysis. Non-inferiority was inferred if the upper limit of the one-sided 95% confidence interval (CI) of the difference between intervention and control group was below the non-inferiority margin of 1 in the ITT (intention-to-treat) and PP (per protocol) population. RESULTS Twenty-one children were randomised and 14 children finished the study per protocol. In the ITT population, hydroxyapatite was non-inferior to amine fluoride (mean difference: -0.75 95%CI [-∞;0.49]). In the PP population, non-inferiority could not be shown (-0.62 [-∞;1.08]). CONCLUSIONS Overall non-inferiority in hypersensitivity relief of a toothpaste containing hydroxyapatite compared to amine fluoride could not be shown. However, the hydroxyapatite group tended to be less hypersensitive in both populations. Attrition of the PP population due to the COVID-19 pandemic led to loss of statistical power.

Abstract
CLINICAL RELEVANCE A minimally invasive esthetic treatment can provide longevity and color stability. SUMMARY This clinical case report describes a minimally invasive approach to mask diffuse and demarcated opacities in permanent anterior teeth in an eight-year-old child who was upset with the appearance of her incisors. Clinical examination showed diffuse opacities in teeth 7, 8, 9, and 10, diagnosed as dental fluorosis associated with yellow demarcated opacity in tooth 9 related to molar-incisor hypomineralization. The treatment was based on conservative dentistry using the low-viscosity resin infiltration technique and resin composite restoration in an attempt to mask the lesions. The follow-up time was 24 months.

Abstract
PURPOSE To verify the prevalence of developmental defects of enamel (DDE) in deciduous teeth and analyse the association with adverse events that occurred during pregnancy and early childhood. MATERIALS AND METHODS In a cross-sectional study, 152 children with an average age of 3.57 ± 1.25 years were examined according to the criteria established by the DDE index. A previously validated questionnaire was given to mothers in order to obtain information regarding: calcium and vitamin D deficiency (measured in mothers); gestational diabetes; gestational undernutrition; weight at birth; neonatal hypoxia; and presence of asthma in early childhood. The clinical exam was conducted by a single examiner calibrated for visual exams (Kappa = 0.84), outdoors on patios of schools with children and examiner knee to knee. Pearson's chi-squared test and Fisher's Exact Test (p < 0.05) were used to determine statistically significant associations between the variables in study. The data were then analysed using a binary logistic regression regression. RESULTS 26.3% of children exhibited DDE. It was possible to verify a statistically significant association between DDE and vitamin D deficiency (p < 0.01), calcium deficiency (p = 0.01), neonatal hypoxia (p = 0.026), and gestational diabetes (p = 0.04). The regression model allowed the conclusion that children who had neonatal hypoxia during childbirth, gestational diabetes or vitamin D deficiency during their gestation were 3.54, 12.47 and 6.40 more likely to exhibit signs of DDE, respectively. CONCLUSION The prevalence of DDE was considered high and was associated with vitamin D and calcium deficiency during pregnancy, gestational diabetes, and neonatal hypoxia.

Abstract
OBJECTIVE This randomized clinical trial evaluated the survival of direct restorations on first permanent molars (FPMs) with molar incisor hypomineralization (MIH) and its impact on self-reported dental pain and dental anxiety. MATERIAL AND METHOD FPMs with MIH of 35 patients aged 7 to 16 years were included. The FPMs were randomized into the following two groups: total-etch (TE-37% phosphoric acid etching) and self-etch (SE-no prior etching). The FPMs were restored with universal adhesive and bulk-fill resin composites. The restoration survival was evaluated according to USPHS criteria modified by a blinded examiner. Dental anxiety (Venham picture test) and dental pain (Faces pain scale-revised) were evaluated before treatment and at 1, 6, and 12 months post-treatment. Survival rates were analyzed by the Kaplan-Meier method and the log-rank test. Nonparametric tests compared pain and anxiety in the follow-up periods. RESULTS A total of 64 FPMs were restored (TE = 33; SE = 31). Survival rates were 96.9% (TE) and 96.7% (SE) after 1 month, 90.5% (TE) and 80.6% (SE) after 6 months, and 80.8% (TE) and 62.3% (SE) after 12 months (p > 0.05). Self-reported dental pain and anxiety level decreased after treatment in both groups (p < 0.05). Self-reported pain decreased after 1 month in SE, but it occurred at 6 months in TE. CONCLUSION Both restorative protocols presented similar longevity, decreasing self-reported pain and anxiety levels. CLINICAL RELEVANCE A universal adhesive could be appropriate for restoration of MIH-affected teeth, and the survival of restorations could be higher in the total-etch technique, reducing dental pain and anxiety.

Abstract
CLINICAL RELEVANCE Total-etch adhesive systems and resin composite are clinically viable dental materials for esthetic restorations in teeth presenting white/yellow/brown hypomineralization stains. SUMMARY Molar-incisor hypomineralization (MIH) is a condition that negatively affects enamel and dentin, especially the first molars and permanent incisors, causing esthetic and functional problems. The present clinical case report presents and discusses the etiology and clinical characteristics of MIH and describes a restorative protocol for MIH-affected teeth.

Abstract
MIH is still a challenge in paediatric dentistry, due to the high sensitivity caused to the first permanent molars, that can greatly reduce the cooperation either for home oral hygiene or for in-office treatment. In this contest the use of ozone emphasises the ART technique (Atraumatic Restorative Treatment) and introduces modern "no aerosol" concept.

Abstract
This case report describes the treatment of a patient who had molar-incisor hypomineralization associated with dental fluorosis, a diagnosis established through a comprehensive review of the clinical record, an intraoral clinical examination, and assessment of photographic records. First, dental hypersensitivity was treated with fluoride varnish, which was applied separately to each dental quadrant. Subsequently, the functional and esthetic reconstruction of the permanent maxillary central incisors was completed in a single session through the placement of direct composite resin veneers. After the treatment, the patient was reexamined monthly for 12 months to evaluate the durability of the restorations. At the 12-month follow-up, no fractures or pigmentations were observed, and only a slight loss of brightness of the restorations was noted. The dental hypersensitivity had been eliminated. When an adhesive restorative technique with composite resin is well executed, it is possible to obtain satisfactory and long-lasting esthetics and relief of painful symptoms.

Abstract
Developmental defects of enamel (DDE) in children range from moderate to severe and may predispose to dental fractures and early childhood caries. The prevalence of DDE in the primary dentition range from 24 to 75 percent, and the right time to diagnose DDE should be as soon as the teeth erupt. However, early detection of DDE in primary incisors is difficult because parents seldom visit the dentist at this age and, later on, caries lesions mask the original alteration. The purpose of this paper was to present three cases of unique and similar dental defects appearing in very young children from different countries-defects that probably share the same etiology. Given the severity of the defects and the children's' age, these could be the first reported cases of preeruptive intracoronal resorption (PEIR) in primary incisors. This paper also discusses the differentiation between DDE and PEIR.

Abstract
Purpose: To determine the prevalence of developmental defects of enamel (DDE) among American Indian (AI) children and whether DDE are associated with caries experience and rehabilitative treatment under general anesthesia (GA). Methods: This retrospective study reviewed charts of 557 AI children, between 12 and 84 months of age, served by one Indian Health Service clinic in Sisseton, SD, USA. Analyses included descriptive and bivariate statistics, including odds ratios (OR). P ≤ 0.05 was considered significant. Results: The overall prevalence of DDE was 32.5% (mean equals 0.87±1.59 per child). The presence of DDE was associated with significantly higher mean decayed, extracted and filled (deft) scores (7.94±5.06 versus 4.84±5.14; P<0.001), predicting adverse clinical outcomes. Children with DDE had 3.8, 4.2, and 3.4 times the odds of having caries, early-childhood-caries (ECC), and severe early-childhood-caries (S-ECC), respectively, than those without DDE. DDE were also associated with higher odds of treatment under GA (OR equals 4.4). Conclusions: DDE were prevalent in this cohort of AI children and found to be significantly associated with a higher caries burden and dental rehabilitation under GA. Early recognition of DDE in infants and toddlers along with targeted prevention programs may help reduce the incidence of caries and subsequent treatment under GA.

Abstract
Purpose: The purpose of this case-control study was to investigate the relationship between molar-incisor hypomineralization (MIH) and pre-, peri-, and postnatal conditions of children and mothers in South Korea. Methods: The Korean Academy of Pediatric Dentistry con- ducted this study to examine factors associated with MIH among six- to 13-year-olds. The European Academy of Pediatric Dentistry criteria and self-administered questionnaires associated with MIH were used. Results: In multivariable logistic regression analysis, the odds ratio (OR) of MIH for children whose mothers used health supplements during pregnancy was 0.65 (P=0.009). Also, children with more than three hours of out- door activities per day tended to have a lower MIH (P=0.03) than did those with zero hours of outdoor activity. Additionally, the OR of MIH for children whose mothers smoked during pregnancy was 2.37 (P=0.019) and the MIH found to be 1.33 times more frequent in children with respiratory infections during the first three years of life (P=0.048). Conclusions: Maternal smoking during pregnancy and child's pediatric respiratory infection suffered within three years after birth are factors associated with the MIH among Korean children. Further study is needed because the prevalence of MIH in children whose mothers taking health supplements (vitamins or folic acid or iron) during pregnancy is low.

Abstract
Hypoplasia is an enamel developmental defect characterized by a quantitative disturbance in the formation of mineralized tissue. Among its etiologic factors are local and systemic causes, trauma and dental infections being the most common. This case report presents the functional and esthetic rehabilitation of a 12-year-old boy diagnosed with hypoplasia in the maxillary central incisors. His chief complaints were the unesthetic appearance and sensitivity of the affected teeth. The teeth were restored with composite resin placed with the aid of a direct silicone palatal guide, and the patient was followed up for 12 months. The treatment plan allowed the restoration and improvement of function and esthetics, resulting in patient satisfaction.

Abstract
Purpose: The prevalence of molar incisor hypomineralization in the United States is unknown. The condition is defined via the presence of demarcated opacities of varying color, porous enamel, advanced susceptibility or progression of dental caries, and sensitivity. The purpose of this study was to establish the prevalence of molar incisor hypomineralization (MIH) in Pittsburgh, Pa., USA. Methods: A total of 104 patients (64 females and 40 males ranging in age from seven to 32 years) from the University of Pittsburgh were screened for the clinical signs of MIH between May 15 and July 31, 2019. MIH was defined according to international guidelines. Results: A total of 9.6 percent of patients screened presented with the clinical signs of MIH; 15.4 percent of patients screened presented with clinical signs aligning with dental fluorosis. Conclusions: Molar incisor hypomineralization is prevalent and clinically relevant in Pittsburgh. American clinicians should start recording the diagnoses of MIH to facilitate establishing national prevalence data and increase knowledge and treatment.

Abstract
Enamel hypoplasia occurs because of a defect in formation of the organic matrix during the development of tooth enamel. Minimally invasive procedures of the slightly altered enamel contribute to a greater longevity of teeth and prevent them from relapsing into the repetitive restorative cycle. This case history report aimed to show a sequential technique of minimally invasive procedures for esthetic resolution in anterior teeth. Prior to microabrasion, anterior teeth were bleached in office with 37% hydrogen peroxide. Afterwards, hypoplastic spots on the buccal incisal thirds of the maxillary central incisors were treated with two sessions of microabrasion using phosphoric acid and pumice stone and one session using resin infiltrant. Besides a slight remaining white spot on tooth 21, the masking of spots was done with this sequence of treatments, re-establishing color harmony. Spot depth, diagnosis, and the most relevant treatment choice determined the clinical success.

Abstract
PURPOSE To determine the prevalence of molar-incisor hypomineralisation (MIH) in 7- to 9-year-old (±1 year) schoolchildren living in Dubai, United Arab Emirates, and to find a possible association with caries, fluorosis and socioeconomic status. MATERIALS AND METHODS In this cross-sectional study, a representative sample of 779 children with an age of 7 to 9 years ±1 year in primary schools in Dubai were randomly selected and examined by one investigator who had previously been trained and calibrated with the diagnostic criteria of European Academy of Paediatric Dentistry (EAPD) for MIH, caries diagnostic criteria of the World Health Organization (WHO) and Dean's criteria for fluorosis. RESULTS The prevalence of MIH in Dubai was 7.57% and was almost identical for both genders (female 7.57% and male 7.58%). The caries index was high (2.41±1.7). Children with MIH in Dubai exhibited statistically significantly higher DMFT values than did children without MIH (mean 3.5 ± 1.7 vs 2.3 ± 1.7; p < 0.001). The prevalence of fluorosis was 10.9% with no statistically significant age or gender differences. CONCLUSION The prevalence of MIH in Dubai is low. However, the caries and fluorosis values are much higher, which calls for strengthening caries-preventive efforts.

Abstract
Dental epidemiological research permits accurate tracking of the prevalence and distribution of oral disease across population groups, enabling planning and evaluation of public health interventions and healthcare service provision. This first section of this paper aimed to review traditional assessment methods in dental epidemiology and to consider the methodological and logistical benefits provided by digital imaging, both generally and specifically in relation to an established dual-camera system. The remainder of this paper describes the results of a semi-structured examination of an image archive from previous research utilising a dual-camera system, exploring whether the diagnostic yield of the images might be increased. Common oral conditions are presented alongside suggestions of the diagnostically useful data displayed in example images. Possible scoring mechanisms are discussed with consideration of the limitations that might be encountered for each condition. The retrospective examination suggests further data is obtainable from images acquired using the dual-camera system, however, consideration should be given to how best to validate this clinically. Additionally, other imaging modalities are discussed whilst taking into account the potential limitations of the dual-camera system.

Abstract
Enamel hypomineralisation is a qualitative defect, with reduced mineralisation resulting in discoloured enamel in a tooth of normal shape and size. Because the enamel is weaker, teeth can undergo post eruptive breakdown, resulting in missing enamel. Enamel hypoplasia is a quantitative defect of the enamel presenting as pits, grooves, missing enamel or smaller teeth. It can sometimes be difficult to differentiate between the two. In this review paper, we aim to explain the importance of differentiating between the two conditions, and how to manage patients presenting with enamel defects.

Abstract
Purpose: Hypomineralized primary second molars (HPSMs) are clinically represented by demarcated opacities in the enamel, involving from one to four primary second molars. The purpose of this cross-sectional study was to investigate the systemic exposures associated with hypomineralized primary second molars. Methods: A representative population-based sample of 731 eight-year-old children was randomly selected. Data on systemic exposures were collected via a structured questionnaire given to the children's mothers. The HPSMs were clinically assessed by calibrated examiners according to the modified-DDE (developmental defects of enamel) index and European Academy of Paediatric Dentistry criteria. Associations were analyzed by Poisson multiple regression considering a temporal hierarchical approach. Results: The prevalence of HPSMs was 9.4 percent (95 percent confidence interval equals 7.0 to 12.0 percent). Children whose mothers presented with hypertension were found with an Adjusted Prevalence ratio (PRa) of 1.73 (P=0.044) and mothers who used tobacco (PRa equals 2.44; P=0.001) during pregnancy had a significantly higher prevalence of HPSMs. The presence of complications during delivery (PRa equals 1.83; P=0.032) and the occurrence of otitis media during early childhood (PRa equals 1.68; P=0.043) also presented a higher prevalence of HPSMs. Conclusion: The use of tobacco, presence of hypertension, complications during delivery, and otitis media during the first years of a child's life are associated with a higher prevalence of hypomineralized primary second molars.

Abstract
PURPOSE To assess the prevalence, severity and defect characteristics of hypomineralised second primary molars in schoolgoing children along with distribution of other phenotypes. METHODS A total of 3013, 3- to 6-year-old children were examined for the presence of hypomineralised second primary molars (HSPMs) using an adapted version of EAPD Criteria (2003). The molars were evaluated for the presence, location and colour of demarcated opacities along with associated post-eruptive breakdown (PEB) and atypical restorations. A thorough examination of the entire dentition was followed for evaluation of teeth other than primary second molars for the presence of similar hypomineralised defects. Data were analysed using Chi Square, Fisher exact's and Mann-Whitney U tests at α = 0.05. RESULTS A total of 3013 out of 3200 children were included having a mean age of 4.25 ± 0.5 years and deft of 2.1 ± 0.5. Using the adapted version of EAPD 2003 criteria for MIH, the children were evaluated for the presence of hypomineralised second primary molars, the prevalence of which was found to be 7.9%. Hypomineralisation defects were more commonly observed in the maxillary arch (53.4% vs. 42.8%, p = 0.04) with creamish white opacities involving the buccal and lingual surfaces being the most common defects (43.6%). The mean number of HSPMs per child was 1.9. Other phenotypes included demarcated opacities majorly on primary canines (6.6%) followed by primary first molars (4.6%). CONCLUSIONS Hypomineralised primary second molars are a fairly common condition affecting approximately 7.9% of the population thus warranting early recognition and management.

Abstract
AIM Estimate the prevalence of developmental defects of enamel (DDE) in the primary dentition, describe the distribution among tooth groups and investigate the association with birth weight. METHODS A cross-sectional study was conducted with a sample of 827 children aged 2-5 years representative of the city of Canela in southern Brazil. Demographic characteristics (gender and age) and birth weight were collected from vaccination cards. The diagnosis of DDE was performed by six trained examiners following the criteria of the Federation Dentaire International. DDE were described both jointly and separately as opacity and hypoplasia. Statistical analysis involved the Chi square test, Mann-Whitney test and Poisson regression with robust variance. RESULTS The prevalence of DDE was 55.1% (95% CI 51.6-58.5%), with a mean of 3.0 ± 2.2 teeth affected. Opacity was the more frequent defect (50.4%), followed by hypoplasia (15.5%). Distribution of the defects was uneven, with opacity predominant on second molars and hypoplasia predominant on canines and second molars. Children with a low birth weight did not have a greater probability of opacity (PR: 1.13; 95% CI 0.91-1.41), hypoplasia (PR: 1.33; 95% CI 0.80-2.22) or DDE (PR: 1.11; 95% CI 0.91-1.37). CONCLUSION The prevalence of DDE was high, predominant on second molars and not associated with birth weight. These findings indicate directions for future examination/diagnosis protocols and specific orientations.

Abstract
OBJECTIVE This article describes the esthetic results in a paradigmatic case of hypomineralized enamel correction on both anterior and posterior teeth to establish a minimal intervention protocol for similar cases. Clinical considerations: The subject was initially provided with casein-calcium-phosphate mineral supplementation. Unpublished laboratory images collected as part of a previously published study depict the results of initial calcium-phosphate supplementation on molar incisor hypomineralization (MIH) molar enamel morphology and indicate that this procedure is mandatory in moderate/severe cases. Prior to defect restoration, in-office bleaching of the anterior segment was conducted with bioactivated Opalescence Boost. Filtek Supreme Ultra Universal Restorative was used as a masking agent, and Filtek A2 enamel was applied as the final layer. CONCLUSION An 8-year follow-up period is necessary in most moderate/severe MIH cases involving orthodontics and bleaching.

Abstract
The aim of the study was to estimate the permanent teeth enamel resistance of 7, 12 and 15-year-old children with different emotional state. Among children with caries-resistant and caries-susceptible enamel the low level of situational anxiety was registered in 49.34±2.13% and 31.52±2.45% of cases, correspondently (p<0.05), while the number of children with high situational anxiety was almost five times more in the group of caries-susceptible enamel than in children with caries-resistant and conditionally resistant enamel (p<0.001). Moderate anxiety level was revealed in 49.32±1.45% of children with caries resistant enamel which is significantly less than in the group of children with caries-susceptible enamel (p<0.05). Low level of personal anxiety in children with caries-susceptible enamel was three times less comparing with caries-resistant children (p<0.05). The study revealed correlation of anxiety level and caries resistance in children which underlines the need for further studies on anxiety impact on dental caries development and prevention programs choice.

Abstract
Orofaciodigital syndrome (OFD) is a group of hereditary disorders identified by malformations of the mouth (oris), face (facies), hands and feet (digitus=finger and toe). Although there are several different types reported in the literature, there is a great overlap in their clinical presentation. The full spectrum of all disorders due to OFD is not yet fully understood, since each patient shows variations in the expression of the syndrome. In the oral cavity, teeth are often affected by various alterations, such as dental caries, abnormal teeth, enamel hypoplasia, supernumerary teeth and dental agenesis. Treatment of a syndromic patient with a complex picture showing conditions such as palatine fissures and a severe hypodontia involves a multidisciplinary approach and a careful periodical follow-up.
