Int J Paediatr Dent 2024; 34:554-566. [PMID: 38200629 DOI: 10.1111/ipd.13156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 12/07/2023] [Accepted: 12/24/2023] [Indexed: 01/12/2024]
Abstract
BACKGROUND Molar incisor hypomineralisation (MIH) is a developmental enamel defect in the first permanent molars and frequently in the incisors. It poses a unique challenge to the dental practitioner because of its nature, clinical presentations and treatment strategies. AIM This study assessed the perception of Libyan dentists in Benghazi regarding MIH and its management. DESIGN Paper-based, self-administered questionnaires were distributed to dentists in Benghazi, Libya. The questionnaires investigated the awareness of MIH, knowledge of MIH aetiology, clinical challenges of MIH treatment and choices of restorative management. Descriptive statistics, chi-squared test and binary logistic regression analysis were performed at a significance level of ≤.05. RESULTS A total of 389 questionnaires were completed and analysed, giving an overall response rate of 76% (389/511). Most participants were female (85%, 332), with an average of 6.05 (SD = 6.24) years of experience. The majority of participants (67%) recognised MIH in their practice. Statistically significant differences in the awareness of MIH and its prevalence were observed according to the type of practice (p ≤ .001) and experience of dentists (p ≤ .001). Dentists working in public dental practice were less familiar with MIH and less likely to report it. Likewise, novice dentists were less aware of MIH than more experienced colleagues. The most reported aetiological factor in MIH was genetics by 60.2% of respondents, followed by environmental contamination (47.6%) and fluorides (42.9%). Most participants (92.3%) considered MIH a clinical problem. Aesthetics and diagnosis were the most reported challenging aspects (59.4% and 44.2%, respectively). The most commonly selected restorative options were high-fluoride glass ionomer cement (43.2%) and preformed metal crowns (41.6%). CONCLUSION The majority of participants reported awareness of the existence of MIH condition. Nevertheless, variations in estimating MIH prevalence and its proper treatment, as well as factors influencing its treatment and diagnosis, were recorded. It is recommended that the current dental curriculum is reviewed, and scientific evidence providing dental practitioners with updated information on the diagnosis and clinical management of MIH should be circulated.

Treatment choice for first permanent molars affected with molar-incisor hypomineralization, in patients 7-8 years of age: a questionnaire study among Swedish general dentists, orthodontists, and pediatric dentists. Eur Arch Paediatr Dent 2024; 25:93-103.

Abstract
PURPOSE The aim of this study was to investigate attitudes and preferred therapy choice for first permanent molars (FPM) with Molar-Incisor Hypomineralization (MIH). METHODS An online questionnaire was sent out to general dentists (n = 559) working in the Public Dental Service in Region Västra Götaland, orthodontists (n = 293), and pediatric dentists (n = 156) (members from each interest association), in Sweden. The questionnaire contained three parts: general questions regarding the respondents, patient cases, and general questions regarding extraction of FPMs with MIH. Statistics were carried out using Chi-squared tests, with a significance level of 5%. RESULTS A response rate of 36% was obtained. Orthodontists and pediatric dentists were more prone to extract FPMs with both moderate and severe MIH, compared to general dentists. When restoring FPMs with moderate MIH, resin composite was preferred. Compared to the general dentists, the pediatric dentists were more prone to choose glass-ionomer cement in the FPMs with severe MIH. The most common treatment choice for FPMs with mild MIH was fluoride varnish. "When root furcation is under development of the second permanent molar on radiographs" was chosen as the optimal time for extracting FPMs with severe MIH, and the general dentists based their treatment decisions on recommendations from a pediatric dentist. CONCLUSION Extraction of FPMs with moderate and severe MIH is considered a therapy of choice among general dentists and specialists, and the preferred time of extraction is before the eruption of the second permanent molar.

Abstract
BACKGROUND Molar-incisor hypomineralisation (MIH) is the most common developmental abnormality observed in teeth. Being a relatively new condition, its treatment can present a challenge for the dentist. There is currently no study available that has evaluated the knowledge of Mexican dental personnel. This study aimed to evaluate the knowledge, experience, and perceptions of dental surgeons regarding the detection, assessment, and treatment of MIH in the metropolitan area of Mexico City. METHODS A cross-sectional study was designed. Dentists from Mexico City and its metropolitan area were invited through social networks to answer a questionnaire of 30 questions related to MIH. Participants were classified into general practice dentists, paediatric dentists, and other speciality dentists. Pearson's chi-square test was used for data analysis. RESULTS The questionnaire was answered by 391 dentists. A total of 86% (338 out of 391) of them identified MIH lesions, while 84% of them reported having observed MIH lesions in their practice. The most frequently observed lesions were yellow-brown opacities which accounted for 47% of the lesions, 46% were white opacities, while only 7% were observed as post-eruptive fractures in the enamel as part of the manifestations of MIH. The most frequently reported problem in the management of teeth with MIH was insufficient training for treating children with MIH. A total of 84% of dentists stated that they would like more information on the treatment of MIH lesions. CONCLUSIONS Most of the surveyed dentists recognised MIH and reported having observed MIH lesions in their practice. Most of the dentists indicated that the main problem for the management of the MIH is the lack of training.

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
BACKGROUND Molar incisor hypomineralization (MIH) is a widespread oral health problem. Dentists encounter several challenges regarding MIH management worldwide. The aim of this study was to evaluate and compare the knowledge, perceptions, attitudes, and clinical experiences on MIH among general dental practitioners and pediatric dentists in Syria. METHODS All general dental practitioners and pediatric dentists belonging to the Syrian Dental Syndicate of Damascus were invited to complete a cross-sectional structured questionnaire (n = 1936). The questionnaire consisted of four sections and required responses regarding demographic data, knowledge, perceptions, attitudes, and experiences on MIH. Data were analyzed with Pearson's chi-square test and multivariate regression models using SPSS Ver. 23.0. RESULTS The overall response rate was 36.31% (703/1936). Pediatric dentists were significantly more familiar with MIH (p < 0.001) and more confident when diagnosing it (p < 0.001). Most participants (43.95%) perceived an increase in MIH prevalence in Syria. Stainless steel crowns were the most favorable restorative material for molars with post-eruptive breakdown (51.38%). As for molars and incisors with opacities, composite resin was preferred with (41.82%), and (67.51%) respectively. General dental practitioners requested further training regarding MIH treatment (p < 0.001). CONCLUSIONS Pediatric dentists were equipped with further knowledge regarding MIH, and were more confident when diagnosing it. There is a need for additional training and education for general dental practitioners. Most respondents perceived an increase in the prevalence of MIH. There is a dearth of data regarding MIH prevalence in Syria. The materials of choice for restoring teeth with MIH were stainless steel crowns and composite resin.

Abstract
Background Molar Incisor Hypomineralisation (MIH) remains a challenge for clinicians underlining the gap in the literature regarding the condition. The study aimed to record knowledge and attitudes of Greek dentists regarding diagnosis and treatment of MIH and correlate findings with non-dental characteristics. Methods It is a cross-sectional study based on a questionnaire consisting of 37 multiple-choice questions. Data regarding diagnosis, aetiopathogenesis, and clinical management of MIH were collected from active members of three Greek Dental Associations. Chi-square and student’s t-test were used to correlate responses with practitioners’ characteristics and odds ratios calculated to evaluate differences on treatment of MIH-affected teeth (p < 0.05). Results From the 360 participants (response rate = 94%), 185 were general dental practitioners (GDPs) and 175 dental specialists (59 paediatric dentists (PDs), 38 orthodontists and 78 of other specialties).MIH was commonly encountered as a clinical problem, with GDPs reporting genetics and fluoride intake as common aetiological factors at significantly higher percentages as compared to PDs (p < 0.05). Permanent molars and incisors (44%) were the teeth most commonly affected, with yellow/brown demarcated opacities (68%) the most common clinical feature with PDs reporting them in a significantly higher percentage (p < 0.05). Dentists with specialisation, dentists that treat > 10 children per week and children with MIH-affected teeth had a 2–5.5 times greater probability to report difficulty achieving sufficient anaesthesia and hypersensitivity problems (p < 0.001). Agreement between GDPs’ and dental specialists’ views was found on less invasive treatment of anterior lesions. Non-PDs reported bulk-fill restorations and onlays as the ideal treatment of severely-affected posterior teeth, as compared to PDs that preferred preformed metal crowns (p < 0.05). Multivariate logistic regression analysis revealed that the age of the clinician, years of experience and number of children treated per week were the factors significantly associated with the decision for the treatment of only severely-affected posterior MIH teeth. Conclusions Most participants had encountered MIH-affected teeth in their clinical practice and were able to recognize main aetiological factors and clinical findings related to the condition. Nevertheless, their knowledge regarding treatment is limited. Supplementary Information The online version contains supplementary material available at 10.1186/s12903-022-02525-3.

Abstract
BACKGROUND Molar-Incisor Hypomineralization (MIH) is a common oral health condition that can lead to difficulties and complications for both dental professionals and patients. It also has a negative impact on the oral health-related quality of life. The present study aimed to assess the knowledge, clinical experience, and perceived need for training of a group of Egyptian dental students regarding MIH. METHODS Paper-based survey administration method was used to collect the responses of dental students regarding their knowledge, clinical experience, and perceived need for training about MIH. The survey consisted of two sections of questions regarding clinical features, etiological factors, prevalence, materials used in treating these teeth, factors affecting the choice of restorative materials, and their preferences regarding clinical training of MIH. Descriptive statistics was used for the data analysis by using SPSS® Statistics Version 26. RESULTS About two-thirds of the respondents were familiar with MIH (69.2%). The vast majority of students (87.8%) had difficulty distinguishing MIH as a developmental defect that differs from other tooth conditions (p < 0.001); most commonly enamel hypoplasia. The most common defects seen by the respondents were yellow/brown opacities (59.1%). Nearly half of the students (45.2%) choose composite resin as the material of choice for the treatment of MIH-affected teeth with aesthetics being the most common factor affecting the selection of restorative material. Almost all students expressed their needs for further clinical training on MIH, especially on treatment aspects. CONCLUSIONS Most students are familiar with MIH theoretically. However, there is an urgent need to include clinical training on MIH diagnosis in the practical sessions of pediatric dentistry courses.

Abstract
Aim Molar incisor hypomineralization (MIH) is a prevalent oral health condition whose knowledge by dentists is key to the best clinical outcome. This study aimed to evaluate the knowledge, perceptions and clinical experiences of MIH among Portuguese dentists.
Methods A cross-sectional structured questionnaire was distributed nationally through a web-based survey platform. Data concerning demographic variables, years of experience, dental specialty, MIH prevalence, diagnosis, severity, training demands and clinical management of MIH were collected. We calculated a knowledge score (KS), and compared data between Pediatric Dentists (PDs), General Dental Practitioners (GDPs) and other dental specialties (ODS). Results Overall, 2.2% of Portuguese dentists (n = 257) answered the questionnaire. Most participants reported having identified MIH in their practice (82.5%), with PD reporting the prevalence appeared to have increased, and practically all (91.7%) considered it a public health problem. Resin composite was often the used material to restore MIH teeth (56.0%), however PDs indicated glass ionomer cements as the preferred and preformed crowns a better option. The average KS on MIH was 41.3 (± 5.7), with GDPs having a similar score than PDs. Most respondents (94.9%) reported a lack of information about MIH and were willing to receive appropriate clinical training. Conclusions The average knowledge on MIH was considered low among Portuguese dentists. Respondents perceived an increased incidence of MIH, despite the lack of prevalence data in Portugal. The material of choice was Glass Ionomer and performed crowns, by PDs, while GDPs and ODS reported poor confidence to manage MIH. These results may serve future programs to increase knowledge, perceptions and clinical experiences towards MIH.

Abstract
Introduction Molar-incisor hypomineralisation (MIH) presents as a spectrum, with severe cases becoming increasingly complex to manage. This study aimed to investigate the perceptions and experience of general dental practitioners (GDPs) in England when managing children with MIH.Method Semi-structured telephone interviews with GDPs who regularly treat children took place in May 2020. A sample of four male and six female GDPs with 1-15 years of experience was achieved through purposively sampling interested parties following advertisement via professional groups. Thematic analysis using a realist and inductive approach was used in analysis.Results The overarching theme was of managing uncertainty, with four subthemes: setting the scene; fighting the tooth; working within the system; and self and interpersonal insight. Despite being knowledgeable, participants expressed varying levels of confidence in many aspects while managing children with MIH. There was a great deal of uncertainty surrounding 'doing the right thing' across the themes. Systemic barriers to managing children with MIH within the general dental service were identified.Conclusion The challenges of managing children with MIH was experienced as 'uncertainty'. Barriers within the general dental service made managing children with MIH difficult and participants relied on colleagues in secondary care to manage severe cases.

Abstract
Background: Molar incisor hypomineralization (MIH) is the presentation of an enamel defect, where incisors and one (or more) molars are affected. Identifying MIH is significant in restoring its visual defect and avoiding pain or other consequences of this condition. The present cross-sectional study aimed to evaluate the awareness, ability, and confidence in identifying MIH among postgraduate residents in the state of Nevada. Methods: This cross-sectional study was conducted among postdoctoral dental residents at the School of Dental Medicine, University of Nevada, Las Vegas. This cross-sectional study used images of cases of MIH and a survey to collect the data. The survey included demographics, educational background, and basic knowledge of MIH. Results: The response rate to the invitation to participate was 91%. The confidence in identifying MIH was 100%, 50%, and 33.3% for pediatric, orthodontic, and general practice residency (GPR). A total of 70% were aware of this anomaly from their predoctoral dental education and indicated the need for further related education. There was 33% confusion with fluorosis and 16.6% with amelogenesis imperfecta. A total of 66.6% of the participants indicated that they require further education relating to MIH. Conclusion: Within the limitations of the present investigation, MIH awareness among the investigated groups varied but was highest amongst the pediatric residents.

Can molar incisor hypomineralization cause dental fear and anxiety or influence the oral health-related quality of life in children and adolescents?-a systematic review. Eur Arch Paediatr Dent 2022; 23:65-78. [PMID: 34110616 PMCID: PMC8927003 DOI: 10.1007/s40368-021-00631-4] [Citation(s) in RCA: 23] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Accepted: 05/05/2021] [Indexed: 12/16/2022]
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
INTRODUCTION/OBJECTIVES Enamel defects are disturbances in the quantity or quality of enamel, due to disruption or damage to the enamel organ during amelogenesis. The correct diagnosis of enamel defects is critical as diverse management options could be required for different conditions. Difficulties in diagnosis can happen, because these defects may have similar clinical presentations. This study evaluated the diagnostic skills in enamel defects of dental students of a prominent Australasian school. METHODS A questionnaire consisting of clinical photographs of the affected teeth/dentition in multiple views and four standardised questions for each case of enamel defect were given to Year 4 and Year 5 students. RESULTS Localised/Chronological Hypoplasia had the lowest percentage of correct diagnosis (20.5%), whilst Enamel White Spot Lesions (EWSLs) had the highest (85%). Localised/Chronological Hypoplasia had the lowest aetiology score (20.5%), and the highest was obtained for EWSLs (85%). In regard to which question to ask to gain insight into the conditions, Enamel Hypomineralisation/MIH had the lowest score for both Year 4 and Year 5 respondents (35.4% and 21.3%). Most respondents agreed more teaching in this topic was needed, with further clinical sessions to observe the enamel defects, workshops/seminars, lectures and student-driven presentations suggested. CONCLUSION Final-year dental students showed variable knowledge in diagnosis, aetiology and clinical management of enamel defects. Further didactic and clinical teaching should be incorporated in the undergraduate curriculum on this topic .

Abstract
Purpose Molar incisor hypomineralization (MIH) is a frequently encountered dental condition worldwide. The aim of this study was to evaluate the knowledge of Austrian dental students about MIH. Methods A validated paper-based survey was distributed among 100 final year dental students at the Medical University of Vienna to assess their knowledge, perception and believes regarding MIH. One hundred dental students at the University Dental Clinic of Vienna were included in the study. At the time of the survey, they were in their 11th or 12th semester (final year). Information about the knowledge on diagnosis and prevalence, and attitudes and beliefs around etiology and management was collected. Results All students replied, 94 questionnaires could be included in the analysis (50% female). 98% of the students were familiar with MIH and 86% were aware with the clinical features of MIH. Only 13% reported clinical ability to identify MIH. Regarding the etiology of MIH, most of the students (69%) named "genetic factors" as the most frequent etiological factor. Conclusion Dental students showed great interest in the topic of MIH, as the majority of all respondents were in favor of deepening their knowledge regarding this topic. The students should be offered opportunities to do this both during and after their studies.

Abstract
Aim The aim of this study is to gather baseline information on knowledge, perceptions, clinical experience and treatment options regarding MIH among dental care providers in Oslo, Norway, before a larger epidemiological study. Methods An electronic questionnaire was distributed to dentists (n = 88) and dental hygienists (n = 47) working in the Public Dental Service (PDS) in Oslo. The questionnaire consisted of five sections related to sociodemographic, clinical experience, perceptions, clinical management and preferences for further training. Descriptive statistics with chi-squared test was used, and level of statistical significance was set to 5%. Results Replies were obtained from 74.1% (n = 100) after two reminders. All respondents encountered MIH in their practice. The respondents’ perception of the prevalence of MIH in Oslo varied. The majority felt confident when diagnosing MIH (86%). The clinicians qualified in the last 10 years felt more confident than those who had qualified earlier (p = 0.016). Most were self-confident when treating these patients (68.3%), however, nearly all (88%) agreed that MIH was a clinical problem. The clinician’s treatment of MIH varied. Difficulties achieving adequate local anaesthetic (71.4%) and the child’s behavioural problems (84.1%) were treatment barriers for the dentists. Approximately two thirds (69%) would like further training, in particular on the aetiology (70%), diagnosis (57%) and treatment (77%) of the developmental disorder. Conclusion All clinicians were familiar with the diagnosis of MIH and experienced the condition to be a clinical problem. Continuing education on aetiology, diagnosis and treatment of MIH is requested by dental health personnel.

Abstract
BACKGROUND Knowledge of molar incisor hypomineralization (MIH) has relevance for paediatric dentists. AIM To assess final-year German dental students' knowledge, attitudes, and beliefs regarding MIH. MATERIALS AND METHODS A previously validated questionnaire was posted to the 31 German dental schools. Demographic covariates as well as knowledge regarding diagnosis and prevalence, and attitudes and beliefs around aetiology and management were collected. RESULTS Twenty-two (71%) dental schools responded and a total of 877 students participated. Most (97%) were familiar with MIH and 88% were aware of the diagnostic criteria for MIH; however, only 42% knew how to implement them. One-third were able to identify MIH and 16% reported diagnostic confidence when doing so; 90% assumed the MIH prevalence to be <10%. Two-thirds of the respondents implicated genetic components as the main aetiological factor of MIH. Resin composite (60%) and preformed metal crowns (46%) were the dental materials most often suggested for restorative management. Almost all (98%) respondents were interested in receiving more clinical training. CONCLUSION German students were familiar with MIH; however, they reported low levels of knowledge and confidence regarding its prevalence and diagnosis. Standardized nationwide, up-to-date curricula should be implemented to educate future dentists in Germany.

Abstract
BACKGROUND Stainless-steel crowns (SSCs) are recommended for restorative treatment of young teeth severely affected by caries, fractures or dental developmental disorders (DDDs). However, despite recommendations and clinical evidence, SSCs are not widely used by general dentists, who favour extraction and more conventional restorations. The present study aimed to investigate the views of and use of SSCs among Norwegian and Finnish dentists. METHODS The present study was a cross-sectional survey among Norwegian and Finnish dentists. An electronic questionnaire was sent to Norwegian and Finnish dentists asking whether they used SSCs and on which indications. In addition, the questionnaire assessed reasons for non-use and dentists' perceptions regarding advantages and challenges in the use of SSCs, as well as the need for additional training. Distributions of background characteristics, use of and views on SSCs were calculated, and statistical significance of the associations between respondents' background and their answers were evaluated. RESULTS Of the 574 Norwegian and 765 Finnish respondents, only 12.0% and 12.9% reported to use SSCs, respectively. The most frequently reported barrier reported by those who did not use SSCs was lack of practical training. The most frequent challenge reported by those using SSCs was difficulties in crown adjustment followed by aesthetic issues, and the most frequently reported advantage was that SSCs maintain the function and occlusion. The majority of respondents reported a need for more information and practical training in the use of SSCs, with hands-on course as their most frequently preferred education type. CONCLUSION Although the value of SSCs for restoring young molars is recognized by Norwegian and Finnish dentists, SSCs are rarely used by general dentists. The majority of the respondents reported lack of training and materials and was interested in receiving more information and education.

Abstract
Introduction Molar-incisor hypomineralisation (MIH) affects one in six children in the UK. For the majority of patients who have mild MIH, this should be managed in primary care.Aims To assess UK-based general dental practitioners' (GDPs) ability to diagnose MIH when presented with multiple clinical vignettes.Design An electronic vignette survey was designed with use of clinical photographs - six cases had MIH and/or hypomineralised second primary molars (HSPMs) (seven possible diagnoses). Four control cases showing caries, fluorosis, amelogenesis imperfecta and dentinogenesis imperfecta were also included. Participants were UK-based GDPs. The survey was distributed by email and across social media platforms. Data collection occurred between February and May 2019.Results Seventy-six GDPs completed the survey; 68.4% (n = 52) of participants were female and 83% (n = 63) of participants graduated after the year 2000. The number of accurate diagnoses for each case were as follows - mild MIH (molars/incisors) 65.79%; mild MIH (molars only) 3.95%; HSPM and MIH (HSPM result) 0%; HSPM and MIH (MIH result) 50%; severe MIH (post-eruptive breakdown) 63.16%; severe MIH (caries) 31.58%; HSPM 3.95%.Conclusion GDPs are able to accurately diagnose MIH best when both incisors and molars are affected and caries is not present.

Abstract
BACKGROUND AND AIM This study aimed to assess the prevalence and clinical status of molar incisor hypomineralisation (MIH) and other enamel defects and associated factors in Libyan children. METHODS A cross-sectional survey of a randomly selected sample of 8- to 10-year-old Libyan school children was conducted in the city of Benghazi, Libya in 2019. The children were assessed for the presence of MIH and enamel defects according to EAPD evaluation criteria. The survey was supplemented by a questionnaire, completed by parents, about potential associated factors occurring before, around and after birth. Association with risk indicators was assessed using chi-square and Mann-Whitney U tests. RESULTS One thousand forty-seven children returned complete questionnaires and attended the clinical examination, with 87% response rate. MIH was the most common form of enamel defects, affecting 162 (15.5%) children. The average number of MIH affected teeth was 3.54 (SD = 1.82). There were no statistically significant associations between the prevalence of MIH and health or demographic characteristics except for the history of early childhood health problems (P = 0.047). CONCLUSIONS In Libyan children, MIH appeared to be the most prevalent type of enamel defects affecting 15.5% of the participants. Although not statistically significant, MIH appeared to be associated with prenatal, perinatal and post-natal challenges.

Abstract
BACKGROUND Molar incisor hypomineralization (MIH) is a growing health problem, and its treatment is a challenge. The purpose of the present study was to evaluate and compare the perceptions, knowledge, and clinical experiences of MIH in general dental practitioners (GDPs) and paediatric dentists (PDs) in Spain. METHODS All dentists belonging to the College of Dentists of the Region of Murcia, in the South-East of Spain, were invited to participate in a cross-sectional survey. They were asked to complete a two-part questionnaire including sociodemographic profiles and knowledge, experience, and perceptions of MIH. Data were analysed using Pearson's chi-square test, Fisher's exact test and Cramer's V test. RESULTS The overall response rate was 18.6% (214/1147). Most respondents were aged 31-40 years (44.86%), with more than 15 years of professional experience (39.72%). They worked mainly in the private sector (84.58%) and were licensed in dentistry (74.30%): 95.45% of PDs had detected an increase in the incidence of MIH in recent years (p < 0.001). Only 23.80% of GDPs claimed to have made a training course on MIH. With respect to the aetiology, chronic medical conditions (p = 0.029) and environmental pollutants (p = 0.008) were the only factors that showed significant between-group differences. Durability (p = 0.009) and remineralization potential (p = 0.018) were the factors where there was a between-group difference in the choice of the restoration material. In the case of post-eruptive fractures and opacities, the preferred material for both groups was resin-modified glass ionomer (RMGIC). However, in incisor lesions, composite was the material of choice for both groups, with significant differences (p = 0.032) in the use of glass ionomer. Most respondents expressed a need for continuing education on MIH. CONCLUSION Spanish dentists perceived an increase in the incidence of MIH. The material of choice was RMGIC for non-aesthetic sectors and composite for incisors. Dentists believe it is difficult or very difficult to manage MIH, since the long-term success of restorations of MIH lesions is compromised because resin adhesion is not good. Both GDPs and PDs believe they need more training on the aetiology, diagnosis, and treatment of MIH.

Abstract
AIM Molar incisor hypomineralisation (MIH) is a significant global health problem frequently encountered by dentists. The aim of this questionnaire-based study was to gain a better understanding of how dentists in the Republic of Ireland perceive and manage MIH. In addition, to compare these findings with results of existing international studies. METHODS Following ethical approval, an online survey was created consisting of 16 questions based on previous surveys regarding perception and treatment of MIH. Photographs and information regarding three specific cases were also included. The questionnaire was distributed by email and the data were analysed using SPSS statistical software. RESULTS The total number of respondents was 230, of which 204 were general dentists. The majority of dentists (58%) reported that they observe MIH on a weekly basis. Those dentists exclusively in private practice and respondents aged 36 and older were less likely to note frequent MIH (p = 0.042). The vast majority of respondents felt either confident or very confident in diagnosing MIH (91%). Overall, 71% reported to feel comfortable managing MIH; however, those in private practice only (p = 0.023) and those aged 36 and older (p = 0.011) were less likely to report being comfortable managing MIH. The most commonly cited barrier to care was the child's behaviour, followed by difficulty in achieving local anaesthesia. Composite resin was the most commonly selected material used to restore teeth affected by MIH (84%). In the scenario on cavity design, the results showed a similar number of dentists selected the most conservative and the most aggressive preparation indicating a disparity among choices. CONCLUSIONS MIH is frequently encountered by Irish general dentists. The overall wide disparity of responses is in line with other studies, and further highlights the need for the development of strong treatment guidelines and continuing dental education to assist dentists in treatment planning for MIH.

Abstract
Purpose: Molar Incisor Hypomineralization (MIH) is a developmental enamel anomaly of systemic origin affecting the first permanent molars and often the permanent incisors. Despite MIH being a prevalent anomaly, its diagnosis and management are challenging for practitioners; including poor anesthesia, failure of restorations, rapid enamel breakdown, poor resin adhesion, and related child anxiety. This study aimed to evaluate knowledge regarding and management of MIH amongst orthodontists and dentists. Study design: The study was performed from March to September 2017 and included 336 dentists and 32 orthodontists. Questionnaires comprised questions on MIH diagnosis, socio-demographic characteristics of the subjects, and photographs of a case of MIH with related questions regarding management. Results: Our results showed that 48% of dentists and 25% of orthodontists misdiagnosed MIH; with misdiagnosis associated with graduation prior to 1986 (p < 0.001). Amongst dentists, 59% applied a fluoridated product and 34% applied fissure sealants in the case of moderate MIH. The application of fluoride was associated with graduation after 1986 (p < 0.0001).Conclusion: Large disparities about knowledge and management of MIH exist between dental practitioners in France. Education regarding diagnosis and management of MIH is necessary.

Abstract
IMPORTANCE Enamel defects of developmental origin affect up to 38% of schoolchildren and is recognized as a global public health challenge. The impaired enamel formation results in pain owing to hypersensitivity, posteruptive breakdowns, rapid caries progression, and extractions in some cases. The etiology is unknown; therefore, prevention is currently not possible. OBJECTIVE To assess the association of a high-dose vitamin D supplementation in pregnant women with enamel defects and caries in their offspring. DESIGN, SETTING, AND PARTICIPANTS Post hoc analysis of a double-blind, single-center, randomized clinical trial, the Copenhagen Prospective Studies on Asthma in Childhood 2010 cohort (COPSAC2010). Enrollment began March 2009 and included 623 women recruited at 24 weeks of pregnancy and 588 of their children. A dental examination was completed at age 6 years in 496 of 588 children (84%). Data were analyzed in 2018. INTERVENTION High-dose vitamin D3 (2400 IU/d; N = 315) or matching placebo tablets (N = 308) from pregnancy week 24 to 1 week post partum. In addition, all women received 400 IU/d of vitamin D3 as part of standard care. MAIN OUTCOMES AND MEASURES Enamel defect was defined as having at least 1 molar affected by demarcated opacity, enamel breakdown, and/or atypical restoration. Caries was defined as decayed, missing, or filled surfaces in both the deciduous and permanent dentitions (World Health Organization standard). RESULTS The risk of enamel defects in the permanent dentition was lower in the offspring of mothers who received high-dose vitamin D supplementation during pregnancy compared with standard dose (15.1% [n = 26 of 172] vs 27.5% [n = 44 of 160]; odds ratio, 0.47; 95% CI, 0.27-0.81). A similar association was observed for the deciduous dentition (8.6% [n = 21 of 244] vs 15.9% [n = 40 of 252]; odds ratio, 0.50; 95% CI, 0.28-0.87). There was no association between supplementation and caries. CONCLUSIONS AND RELEVANCE High-dose vitamin D supplementation during pregnancy was associated with approximately 50% reduced odds of enamel defects in the offspring. This suggests prenatal vitamin D supplementation as a preventive intervention for enamel defects, with a clinically important association with dental health. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT00856947.

Abstract
BACKGROUND Molar incisor hypomineralization (MIH) is an alarming problem with considerable challenges in management. This study aimed to evaluate and compare the knowledge, perceptions, and clinical experiences of molar incisor hypomineralization (MIH) between general dental practitioners (GDPs) and paediatric dentists (PDs) in Hong Kong. METHODS A cross-sectional survey of 557 randomly selected GDPs (approximately 25% of all registered dentists) and all registered PDs (n = 31) were invited. They were asked to complete a 4-section questionnaire adapted and modified from a study by Gambetta-Tessini and co-workers on sociodemographic profiles, knowledge, experience, and perceptions regarding MIH. Data were analyzed with chi-square, Fisher's exact, and multiple factor ANCOVA tests. RESULTS The overall response rate was 43.37% (255/588). Majority (74.1%) of the respondents encountered MIH in their practices. A significantly higher mean knowledge score (46.33 ± 7.1) was observed among PDs than GDPs (43.09 ± 7.0) (P < 0.01) and among PDs who are 40 years old or younger (P < 0.001). Differences in treatment of MIH were also observed between PDs and GDPs (P < 0.05). Paediatric dentists were more confident in diagnosing and treating MIH (P < 0.001). Most respondents (87.8%) expressed a need for continuing education on MIH. CONCLUSION Continuing education on MIH is needed to assure that the highest quality of evidence-based care is given to patients with MIH. Dissemination of latest best evidence on MIH, especially to GDPs, will assure that the condition is accurately diagnosed and well managed.

Abstract
Aim To determine the perception of Indian dental professionals about prevalence, severity, and etiological factors of molar incisor hypomineralization (MIH). Materials and methods An online survey was mailed to dental professionals encompassing various questions regarding etiology, diagnosis, prevalence, and management of MIH. Results More than 90% of the respondents encounter teeth with hypomineralization in their practice, with less than half of them encountering such teeth on a monthly basis. Among these more than one-third find it difficult to manage one or the other aspect of MIH. The etiology was found to be varying as per the respondents. Conclusion Molar incisor hypomineralization is a common condition encountered by dental professionals with no apparent consensus regarding the anticipated prevalence, severity, and etiology of this condition. Knowledge of clinicians' level of perception could be an incentive for pediatric dentists to become more acquainted with MIH by conducting research into its different aspects.How to cite this article: Upadhyay S, Kumar G, Dhillon JK, Gill NC.

Abstract
Background Molar-incisor Hypomineralisation (MIH) is considered as a global dental problem. There is little knowledge of general dental practitioners (GDPs) and dental specialists (DSs) about this condition in different parts of the world, particularly in Gulf Cooperation Council (GCC) countries. Hence, this study has been carried out to assess the knowledge of GDPS and DSs in Kuwait about MIH condition, its clinical presentation and management. Findings would help national school oral health program (SOHP) to promote good oral healthcare. Methods A structured questionnaire was distributed to 310 attendees of the 18th Kuwait Dental Association Scientific Conference, Kuwait. Data concerning demographic variables, prevalence, diagnosis, severity, training demands and clinical management of MIH were collected. Results A response rate of 71.3% (221/310) was reported. 94% of respondents noticed MIH in their practice. Yellow/brown demarcation has been observed as a common clinical presentation (> 50%). Almost 10–20% of MIH prevalence has been reported by the participants. Resin composite was the dental material often used in treating MIH teeth (~ 65%), and fewer than half would use it for treating moderately affected molars. Most respondents would use preformed metal crowns for severe MIH (63%). Dental journals were the information source for DSs; whereas, the internet was the information source for GDPs. Child’s behaviour was the main reported barrier for treatment of MIH affected children. Many GDPs felt unconfident when diagnosing MIH compared to dental specialists. Respondents supported the need to investigate MIH prevalence and to receive a clinical training. Conclusions Molar incisor hypomineralisation is a recognised dental condition by practitioners in Kuwait. Yellow/brown demarcated opacities were the most reported clinical presentation, and the composite resin was the most preferred dental material for restoring MIH teeth. Most GDPs and dental specialists would use preformed metal crowns for severely affected molars. GDPs reported low levels of confidence in MIH diagnosis which necessitates conducting continuing education courses to provide high- quality dental care for children with MIH.

Abstract
OBJECTIVE A growing number of studies have investigated the prevalence of Molar Incisor Hypomineralization (MIH) around the world. The aim of this study was to systematically estimate the pooled prevalence of MIH. METHODS A comprehensive literature research was completed in English and Chinese databases. Random effect models were used to calculate the pooled prevalence. To address the heterogeneity, meta-regression, and sensitivity analyzes were conducted. Publication bias was estimated by trim and fill method. RESULTS Seventy eligible studies were included. The pooled prevalence of MIH was 14.2% globally. In subgroup analysis, South America (18.0%, 95% CI: 13.8-22.2) and Spain (21.1%, 95% CI: 17.7-24.6) had the highest prevalence. There was no significant difference between males (14.3%, 95% CI: 12.0-16.6) and females (14.4%, 95% CI: 12.8-15.9). The prevalence of MIH among children 10 years of age or younger (15.1%, 95% CI: 12.1-18.2) was much higher than the prevalence of MIH among older children (12.1%, 95% CI: 8.0-16.3). Sample size explained 15.7% heterogeneity. CONCLUSION MIH has a high incidence globally, especially among children <10 years old. It is, therefore, imperative to develop more appropriate dental healthcare strategies to care for these children and to identify the etiology of MIH to prevent it occurring.

Abstract
OBJECTIVE The objective of this study was to investigate the effect of fluoride varnish on remineralization of anterior teeth affected by Molar-Incisor Hypomineralization (MIH) by means of Quantitative Light-Induced Fluorescence- QLF. STUDY DESIGN Fifty-one healthy 9 - 12- year-old children were selected according to different clinically diagnosed levels of MIH, proposed by the European Academy of Pediatric Dentistry (2003) (considering the most severe lesion per patient, n= 51 lesions), and randomly divided into two groups: (1) four applications of 5% NaF varnish, with one-week interval, and (2) usual home care- control. At each visit, the mean change in fluorescence and area of lesion were measured by QLF. The data were analyzed by repeated measures ANOVA and Tukey's test. RESULTS All patients showed enamel alterations in first permanent molars and incisors, frequently with two molars affected by MIH (41.1%). There was no statically significant difference in the mean of fluorescence and area of lesion between groups over the studied time. CONCLUSION We observed no favorable effect on the remineralization of MIH lesions in anterior teeth after four applications of fluoride varnish.

Abstract
Background Molar-Incisor Hypomineralisation (MIH) is a prevalent developmental defect of tooth enamel associated with a high burden of disease. The present study aimed to survey Australian and Chilean oral health care practitioners (OHCPs) working in public dental facilities and to compare their knowledge, clinical experience and perceptions about MIH. Findings would give insights about how current knowledge has penetrated into OHCPs working into the public systems. Methods A mixed-mode survey regarding MIH was carried out amongst Australian and Chilean OHCPs from the public sector. The survey required responses to questions regarding sociodemographics, clinical experience, perceptions, clinical management and preferences for further training. The level of knowledge regarding MIH was determined by Delphi methods for consensus. Data analysis utilised Chi-square, linear and logistic regression models using SPSS Ver. 22.0. Results The majority of respondents had observed MIH in their patients (88.6 %) and the level of knowledge regarding MIH was high in Australian participants (p = 0.03). Australian respondents felt more confident when diagnosing (OR 8.80, 95 % CI 2.49–31.16) and treating MIH-affected children (OR 4.56, 95 % CI 2.16–9.76) compared to Chilean respondents. Oral health therapists reported higher levels of confidence than Australian general dental practitioners when providing treatment to children with MIH (OR 7.53; 95 % CI 1.95–29.07). Conclusions Continuing to update clinical guidelines may help practitioners increase their understanding when diagnosing and treating MIH-affected children. Dissemination of information and awareness regarding MIH is necessary in public clinics, and in particular Chilean general dental practitioners should be alerted to these factors.

Abstract
AIM This was to investigate the association of peripartum events with the occurrence of MIH. METHODS This study, carried out between 2010 and 2011, was based on objective information noted in child health booklets on putative risk factors for MIH during the Peripartum period, aged between 6 to 28 years. The target population consisted of patients with MIH and a control group. Among the 849 patients examined by two calibrated paediatric dentists, 75 patients with MIH were recorded. These patients attended for consultation either at the teaching dental hospital of Bordeaux (France) or at a private dental practice (Bordeaux, France). Pearson's Chi-squared test was used and Odds ratios (OR) with 95 % test-based confidence intervals (CI) were calculated. RESULTS Correlations were observed between hypoxia during delivery and occurrence of MIH (OR = 6.1; CI = 1.7-21.85), and also between birth by caesarean section and MIH (OR = 2.9; CI = 1.2-6.9). There was no association between prematurity and MIH. CONCLUSIONS Peripartum events such as hypoxia during birth or delivery by caesarean section are suggested to be risk factors for the occurrence of MIH in this population.

Abstract
Background The study aimed to explore the variability between the treatment decisions dentists make for MIH-affected teeth. Methods In 2009, a pre-coded questionnaire was sent electronically to all dentists employed by the Public Dental Service (PDS) in Norway (n = 1061). The questions were related to treatment of MIH-affected teeth, including three patient cases illustrated by photographs and written case descriptions. Results Replies were obtained from 61.5 % of the respondents after two reminders. In the first case, showing a newly erupted first permanent molar with moderate hypomineralization and no disintegration of the surface enamel, the preferred treatment among the majority of the respondents (53.5 %) was application of fluoride varnish, while 19.6 % would seal the fissure with GIC material. In the second case, showing a severely damaged first permanent molar in a six year old child, more than half of the respondents (57.5 %) would place a conventional glass ionomer restoration and 10.5 % would use a stainless steel crown (SSC). In the third case, showing a severely damaged permanent first molar in a nine year old child, 43.8 % of the dentists would remove only the parts with soft, damaged enamel; while 35.2 % would remove more and 21.0 % would remove all affected enamel and leave the cavity margins in sound enamel. Conclusions The survey shows that there is a wide disparity between clinicians’ views on how MIH affected teeth should be treated. In a severely affected first permanent molar, only a minority of dentists would remove as much tooth substance as needed to get the full benefit of the acid etch pattern in sound enamel.

A practical method for use in epidemiological studies on enamel hypomineralisation. Eur Arch Paediatr Dent 2015; 16:235-46.

Abstract
With the development of the European Academy of Paediatric Dentistry (EAPD) judgment criteria, there has been increasing interest worldwide in investigation of the prevalence of demarcated opacities in tooth enamel substance, known as molar–incisor hypomineralisation (MIH). However, the lack of a standardised system for the purpose of recording MIH data in epidemiological surveys has contributed greatly to the wide variations in the reported prevalence between studies. The present publication describes the rationale, development, and content of a scoring method for MIH diagnosis in epidemiological studies as well as clinic- and hospital-based studies. The proposed grading method allows separate classification of demarcated hypomineralisation lesions and other enamel defects identical to MIH. It yields an informative description of the severity of MIH-affected teeth in terms of the stage of visible enamel destruction and the area of tooth surface affected (i.e. lesion clinical status and extent, respectively). In order to preserve the maximum amount of information from a clinical examination consistent with the need to permit direct comparisons between prevalence studies, two forms of the charting are proposed, a short form for simple screening surveys and a long form desirable for prospective, longitudinal observational research where aetiological factors in demarcated lesions are to be investigated in tandem with lesions distribution. Validation of the grading method is required, and its reliability and usefulness need to be tested in different age groups and different populations.

Abstract
BACKGROUND Current molar hypomineralisation (MH) indices do not guide clinicians in management of affected dentitions, and treatment is based on individual judgment. AIM The aims of this study were to describe characteristics of MH and molar incisor hypomineralisation (MIH) and trial the new Molar Hypomineralisation Severity Index (MHSI). DESIGN First permanent molars (FPMs) and permanent incisors (PIs) in 283 affected children were examined for hypomineralisation characteristics [defect colour, location, post-eruptive breakdown (PEB); restorations placed/replaced/atypical; sensitivity]. The MHSI scores were compared with treatment received (152 children). RESULTS Mean (SD) affected teeth/dentition were as follows: FPMs: 3.2 (1.0) and PIs: 1.6 (1.6). Affected FPMs showed no arch or quadrant predilection; maxillary central PIs were affected particularly. As affected FPMs/dentition increased, MIH diagnoses also increased (P = 0.009). Among FPMs, defects most prevalent were brown (47%) and cuspal (74%); 67% showed PEB. Before study entry, 43% of FPMs had restorations placed/replaced. Among PIs, white defects were common (65%) on smooth surfaces; sensitivity was rare. Affected FPMs received more restorations and extractions than unaffected FPMs (P = 0.0001). As MHSI scores increased, FPM treatments/dentition increased (number, invasiveness). All characteristics were significant in predicting treatment (logistic regression model). CONCLUSIONS A spectrum from MH to MIH occurred. The MHSI characteristics were predictive of the treatment of affected FPMs and can guide management.

Abstract
AIM To investigate the prevalence of molar-incisor hypomineralisation (MIH) amongst primary schoolchildren of Shiraz, Iran, taking into account the possible influence of biographic and socio-demographic parameters. STUDY DESIGN AND METHODS A randomised cluster sample of 9- to 11-year-old children (N = 810) had their first permanent molars and incisors (index teeth) evaluated using the European Academy of Paediatric Dentistry criteria for MIH. The examinations were conducted at schools by a calibrated examiner. Prevalence of MIH was assessed based on biographic and socio-demographic parameters including area of residency, school type, father's level of education, weight-for-age and height-for-age. RESULTS AND STATISTICS Of the children examined, 164/810 (20.2%) had MIH and 53.7% of them presented with MIH lesions in all first molars. Mild defects represented by demarcated yellow brown opacities comprised 35.5% of the total MIH lesions. The prevalence of MIH was significantly greater in girls, children with healthy body weight and height, those whose fathers did not have a tertiary education and from families of low socio-economic status. Regression analyses indicated that none of the biographic and socio-demographic variables represented a significant risk factor in the occurrence of MIH except for body weight. Obesity was negatively correlated to MIH (OR = 0.45; 95% CI 0.25-0.82). CONCLUSIONS The prevalence of MIH in a group of Iranian children was 20.2%. Biographic and socio-demographic parameters appeared to have no significant correlation with MIH except body weight, which warrants further research.

Abstract
OBJECTIVES To investigate and clarify physical and chemical properties of enamel affected by molar incisor hypomineralisation (MIH). METHODS A series of in vitro studies were performed on extracted molars affected by MIH and sound teeth for controls. Tooth sections underwent Vickers microhardness testing before lapping and subsequent transverse microradiographic analysis and examination under polarised light microscopy. Carbonate content was determined by CO2 release from acid digestion. Unprepared and fractured surfaces were examined under scanning electron microscopy. RESULTS MIH-affected molars demonstrated a severe degree of hypomineralisation with an average mineral content of only 58.8%vol% mineral. Vickers microhardness was significantly reduced in MIH compared with controls (1.8±1.1 v 4.4±1.0 GPa, p<0.05) and polarised light microscopy revealed the bulk of MIH lesions had a porosity of ≤5% but also substantial areas of ≥10% and smaller areas exceeding 25% porosity. A surface layer was frequently observed on both intact and broken-down lesions and cervical regions of MIH teeth were typically spared. Carbonate content of MIH enamel was higher than control samples (6.6±2.1 v 4.4±1.1 wt%, p<0.05). Scanning electron microscopy showed that both the enamel rod and surface ultrastructure were defective. Clinical characteristics did not consistently correlate with all properties. CONCLUSIONS The properties of MIH-affected enamel significantly differ from those of normal enamel and were highly variable, however some common characteristics were observed. Implications for aetiology and clinical management are discussed.

Abstract
SUBJECTS All children (n = 217) attending the second to fifth years of comprehensive schools in the nonfluoridated town of Lammi, Finland, were invited to participate in the study. Of those invited, 147 (67.7%) agreed to participate and study data were obtained for 141. The children ranged in age from 7.8 to 12.7 years with a mean of 10.7 years. Slightly more than half (53.9%) of the children were male. No other information was presented. KEY RISK/STUDY FACTOR The key study factor was antibiotic use during the first, second, third, and fourth years of life. Information on amoxicillin, penicillin V, cephalosporin, macrolides (erythromycin), sulfonamide, and trimethoprim use was obtained from the local health center medical records. MAIN OUTCOME MEASURE The outcome measure was hypomineralization of the permanent first molars. A tooth was considered to be hypomineralized if it had a demarcated opacity, broken-down hypomineralized enamel, or an atypical restoration. Lesions smaller than 2 mm in diameter were excluded. The potential issue of missing first molars and how they should be classified was not addressed. MAIN RESULTS Eighty-five percent of the children had received at least one course of antibiotics. During the first year of life, 34.8% had taken either penicillin or amoxicillin or both, whereas 5.0% received erythromycin. Twenty-three children (16.3%) had one or more permanent first molars with hypo-mineralization. Of the children with molar hypomineralization (MH), 12 (52.2%) had taken antibiotics during the first year of life compared with 33.9% of the children without MH (P > .05). The unadjusted odds ratio (OR) for MH among children who received amoxicillin during the first year was 2.06 (95% confidence interval [CI] 1.01-4.17), whereas the unadjusted OR for MH was 4.14 (95% CI, 1.05-16.4) among children who received erythromycin during the first year. CONCLUSIONS The authors concluded that the early use of amoxicillin is among the causative factors of molar hypomineralization. STUDY 2 SUMMARY SUBJECTS: Mandibular molar explants from 27 mouse embryos in an organ culture. KEY RISK/STUDY FACTOR Exposure to amoxicillin at 100 mg/mL, 1 mg/mL, and 4 mg/mL. MAIN OUTCOME MEASURE Enamel and dentin thickness after 10 days of culture. MAIN RESULTS In first molars with enamel, the enamel-dentin layer was thicker in explants exposed to amoxicillin at concentrations of 1 mg/mL or more compared with controls and those exposed to 100 mg/mL (P < .001). The enamel/dentin ratio also differed significantly (P < .007). The actual thickness data were not presented. CONCLUSIONS The authors concluded that the early use of amoxicillin is among the causative factors of molar hypomineralization.

Abstract
OBJECTIVES The objectives were to investigate the prevalence of the condition, by using transillumination, in a group of children. Analysed the prevalence with regard to gender, jaw affected, and the teeth that exhibited dysplasia most commonly. METHODS A sample of 550 children aged 6 to 14 years was selected at the Department of Paediatric Dentistry at the Universitat Internacional de Catalunya, but among those selected only 505 children were eligible for inclusion in the study. The gender and age of the child, number of permanent teeth, number of teeth affected by MIH and their position were registered. RESULTS Ninety patients (17.85%) had MIH. Of these, 45 were girls (50%) and 45 were boys (50%). A total of 8062 permanent teeth were observed. Of these, 344 (4.2%) were affected by MIH. Of the teeth affected, 198 (57.7%) were located in the maxilla and 146 (42.4%) in the mandible. This result was statistically significant (P = 0.003). CONCLUSIONS The population studied showed a prevalence of MIH of 17.8%. The presence of the defect did not differ according to sex in this population. Defects were more common among teeth in the maxilla.

Abstract
BACKGROUND. Little prevalence data relating to molar incisor hypomineralisation (MIH) exist for Middle East populations. AIM. To evaluate the prevalence and the clinical features of MIH in school-aged children residing in Mosul City, Iraq. DESIGN. A cluster sample of 823 7- to 9-year-old children had their first permanent molars and incisors (index teeth) evaluated using the European Academy of Paediatric Dentistry (EAPD) criteria for MIH. The examinations were conducted at schools by a calibrated examiner. RESULTS. Of the children examined, 177 (21.5%) had hypomineralisation defects in at least one index tooth, 153 (18.6%) had at least one affected first molar or first molars and incisors and were considered as having MIH. The most commonly affected teeth were maxillary molars. Demarcated creamy white opacities were the most frequent lesion type. Dental restorations and tooth extraction because of MIH were uncommon. Children with three or more affected teeth were 3.7 times more likely to have enamel breakdown when compared with those children having only one or two affected teeth. CONCLUSIONS. Molar incisor hypomineralisation was common amongst Iraqi children. Demarcated opacities were more prevalent than breakdown. The severity of the lesions increased with the number of affected teeth. The more severe the defect, the greater the involved tooth surface area.

Abstract
BACKGROUND The understanding and detection of molar-incisor hypomineralisation (MIH) is linked to its recognition by clinicians. No study has investigated dental clinicians' level of perception regarding MIH in the Middle East region including Iraq. AIM To determine the perception of Iraqi academic clinicians about MIH prevalence, severity and aetiological factors. DESIGN A questionnaire, based on previous European and Australian/New Zealand studies was administered to the academic dental staff of Mosul University. RESULTS A response rate of 77.7% was reported. General dental practitioners represented 30.8% of the total respondents, whilst 65.1% were dentists with post-graduate qualification. The majority of the respondents (81.2%) encountered MIH in their clinical activities and 37.3% of them identified that the prevalence appeared to have increased in recent years. Fewer than half of the respondents observed MIH affected teeth on a monthly basis. The condition was less commonly seen in primary second molars than the first permanent molars. A variation in views was recorded about MIH specific aetiological factor/s. Respondents advocated the need for clinical training regarding MIH-aetiological and therapeutic fields. CONCLUSIONS Molar-incisor hypomineralisation is a condition commonly diagnosed by Iraqi dental academics. No apparent consensus existed between the general and specialist dentists regarding the anticipated prevalence, severity and aetiology of this condition.

Abstract
BACKGROUND Molar-Incisor-Hypomineralisation (MIH) is a qualitative defect of 1-4 first permanent molars with or without the maxillary and mandibular permanent incisors. It seems to have been recognised first in the 1970s and prevalence varies between 2.8% and 25%, dependent upon the study. METHODS The dental literature was searched using a number of key terms entered into MEDLINE, the reference list of each paper as located was examined for further papers that had been missed in the initial search. RESULTS The review of the literature showed that teeth that are affected indicate a systemic cause at around the time of birth; investigators have put forward a number of possible causes; asthma, pneumonia, upper respiratory tract infections, otitis media, antibiotics, dioxins in mother's milk, tonsillitis and tonsillectomy and exanthamatous fevers of childhood. However, at the present time the aetiology remains unclear. Treatment of the affected permanent first molars can include restorations using adhesive intra-coronal restorations to extra-coronal restorations (e.g. preformed metal crowns). There is little evidence to support one option over another. In severe cases extraction at the optimum time may be the best option; allowing the permanent second molars to come forwards. There is little improvement in affected anterior teeth with microabrasion and direct or indirect composite resin restorations may be appropriate in some children. Ultrastructural and biochemical make up of MIH affected teeth seem to have been investigated less than other areas. CONCLUSION It is important that children with MIH are diagnosed as early as possible and managed appropriately; this will involve multidisciplinary input.

Abstract
OBJECTIVE The objective of this study was to assess the strength of evidence for the aetiology of molar-incisor hypomineralization (MIH), often as approximated by demarcated defects. METHOD A systematic search of online medical databases was conducted with assessment of titles, abstracts, and finally full articles for selection purposes. The level and quality of evidence were then assessed for each article according to Australian national guidelines. RESULTS Of 1123 articles identified by the database search, 53 were selected for review. These covered a variety of potential aetiological factors, some of which were grouped together for convenience. The level of evidence provided by the majority of papers was low and most did not specifically investigate MIH. There was moderate evidence that polychlorinated biphenyl/dioxin exposure is involved in the aetiology of MIH; weak evidence for the role of nutrition, birth and neonatal factors, and acute or chronic childhood illness/treatment; and very weak evidence to implicate fluoride or breastfeeding. CONCLUSION There is currently insufficient evidence in the literature to establish aetiological factor/s relevant for MIH. Improvements in study design, as well as standardization of diagnostic and examination protocols, would improve the level and strength of evidence.
