Impact of Molar Incisor Hypomineralization on Oral Health-Related Quality of Life in Brazilian Schoolchildren Aged 8 to 10 Years

ABSTRACT Objective: To assess the impact of Molar Incisor Hypomineralization (MIH) and confounding factors on oral health-related quality of life (OHRQoL) according to the perception of 8 to 10-year-old children and their parents/caregivers. Material and Methods: A cross-sectional study including 403 students aged 8-10 years was carried out, in which OHRQoL was measured using the Child Perceptions Questionnaire administered to both children and parents/caregivers. The diagnosis of MIH was performed according to the previously proposed index. Dental caries experience, malocclusion, and sociodemographic factors were evaluated as confounders. Cluster analysis and Poisson regression with robust variance (p<0.05) were performed. Results: The prevalence of MIH was 13.4%. Parents/caregivers of children with MIH in incisors showed a higher impact prevalence in the emotional well-being domain (PR=1.92; 95%CI=1.16-3.19). Children with hypoplasia had a higher prevalence of negative impact on OHRQoL in the oral symptoms domain (PR=1.51; 95%CI=1.03-2.23). According to the perception of parents/caregivers, dental caries experience had a negative impact on the quality of life of students in the emotional well-being domain (PR=4.19; 95%CI=1.06-16.49) and in the total questionnaire score (PR=3.21; 95%CI=1.06-9.71). Conclusion: According to the perception of parents/caregivers, children with MIH in incisors showed a greater impact on OHRQoL. Additionally, the presence of hypoplasia affected the self-perception of OHRQoL in children, and caries experience influenced the OHRQoL of children, as perceived by parents/caregivers.

Prevalence of Dental Fear and its Association with Painful Oral Conditions in Adolescents

ABSTRACT Objective: To estimate the prevalence of dental fear and evaluate its association with dental caries and with Molar Incisor Hypomineralization (MIH) in schoolchildren aged 11-14 years. Material and Methods: A cross-sectional study was conducted with 375 adolescents in Campina Grande, Brazil. Socioeconomic and oral health information was collected, while dental fear was measured using the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). The diagnosis of dental caries and MIH was performed by three trained examiners (κ ≥ 0.61) using the International Caries Detection & Assessment System - ICDAS II and a previously validated index, respectively. Data were descriptively analyzed using the Chi-Square, Fisher's Exact, and Poisson regression tests with robust variance (p<0.05). Results: The prevalence of dental fear was 18.4%, and the mean CFSS-DS total score was 28.96 ± 8.92. After adjusting for covariates family structure, schooling of parents/guardians, type of dental health service and dental pain in the last six months, the prevalence of dental fear was associated with dental pain in the last six months (PR=2.03; 95%CI=1.31-3.16; p=0.002). Conclusion: Although no association was found between dental fear, dental caries and MIH in adolescents, those who experienced dental pain in the last six months had a higher prevalence of dental fear.

Craniofacial trauma in Brazilian child victims of traffic accidents: A single-trauma center analysis.

BACKGROUND: Road traffic accidents are a significant public health problem and a major cause of economic loss globally. OBJECTIVES: The aim of the study was to describe the epidemiological profile of child victims of traffic accidents and the prevalence of craniofacial trauma in a municipality in the northeastern region of Brazil. MATERIAL AND METHODS: A documentary study was carried out through the analysis of the medical records of the traffic accident victims hospitalized in emergency wards in the municipality of Campina Grande, Paraíba, Brazil, from January to December 2016. A total of 1,884 medical records were evaluated, among which 85 (4.5%) referred to children aged 0-12 years. The information related to the sociodemographic profile of the victims, traffic accidents and clinical variables was collected. The data was analyzed using descriptive and inferential statistics, and a 5% level of significance was adopted. RESULTS: The victims were predominantly males (64.7%) and 9-12-year-old children (43.5%). Most accidents were recorded in the evening (48.2%) and on the weekend (32.9%). Among the victims, 37.6% were involved in motorcycle accidents. Craniofacial injuries were found in 44.7% of the children. Most victims were not admitted to the intensive care unit (ICU) (80.0%). Craniofacial trauma was significantly associated with motorcycle (p = 0.043) and automobile accidents (p = 0.013). CONCLUSIONS: Our findings suggest that motorcycles are the vehicles most frequently involved in traffic accidents, which predominantly affect males and children aged 9-12 years, and result in a high prevalence of craniofacial trauma.

Head and Face Injuries in Brazilian Homicide Victims - A Retrospective Study.

INTRODUCTION: Violence is a serious problem in view of its magnitude and impact on the health of the population in several countries. The aim of the study was to evaluate the occurrence of head and face injuries among homicide victims in a municipality in the Northeastern region of Brazil. MATERIALS AND METHODS: A cross-sectional study carried out at the Police Station for Crimes against Persons of the Civil Police, which evaluated 168 police inquiries of homicide victims notified from January 2015 to December 2018. Variables analyzed were related to the Victim's sociodemographic profile, homicide characteristics and body region involved. Descriptive data analysis and Pearson's Chi-square test (P < 0.05) were performed. RESULTS: There was greater involvement of men (92.9%) aged 20-29 years (36.3%), drug users (70.7%) and with a criminal record (65.9%). There was a predominance of simple homicides (92.3%), with greater occurrence on Sundays (16.7%), in the night shift (40.1%), revenge was the main reason for the crime (32%), and firearms as the main means used (89.2%). Regarding the number of body regions affected, victims were more frequently affected in 2 regions (36.5%). Head injuries were identified in 68.3% of victims, while face injuries represented 35.3%. There was an association between the presence of head injuries and number of injuries (P < 0.05). DISCUSSION: The prevalence of head and face injuries resulting from homicide was high and victims are predominantly young men, drug users and those with a criminal record. The association was found between the presence of head injuries and number of injuries.

Presence of molar-incisor hypomineralization is associated with dental caries in Brazilian schoolchildren.

This study aimed to identify the prevalence of molar-incisor hypomineralization (MIH) in schoolchildren and its association with dental caries experience. This was a cross-sectional study with a sample of 471 children aged 8 to 10 years. Data were collected via a sociodemographic questionnaire. Intra-oral clinical examination was done to identify and diagnose MIH (EAPD Criteria) as well as dental caries (ICDAS Index). Statistical analyses were performed with Person's Chi-square, Fisher's exact, and Mann-Whitney tests, and Poisson regression models were built. Statistical significance was set at an alpha-level of 0.05. The prevalence of MIH in our participants was 9.8%, with lesions being mostly of the mild form (65.2%) and affecting the first permanent molars but not the incisors in 54.2% of the children. Dental caries was observed in 88.1% of subjects. We observed a significant association between dental caries and the following variables: presence of MIH (p < 0.01; PR = 1.13), dental visit (p < 0.02; PR=0.92), and parents or legal guardians' education level (p < 0.05; PR = 1.07). A MIH diagnosis was also significantly associated with family income (p < 0.05; PR = 4.09). Children with MIH had more caries lesions on molar surfaces (p < 0.01; PR = 4.05). The prevalence of MIH was found to be moderate, based on previous studies, and the presence of enamel defect was associated with dental caries. The teeth most affected by MIH lesions were the first permanent molars.

Abstract This study aimed to identify the prevalence of molar-incisor hypomineralization (MIH) in schoolchildren and its association with dental caries experience. This was a cross-sectional study with a sample of 471 children aged 8 to 10 years. Data were collected via a sociodemographic questionnaire. Intra-oral clinical examination was done to identify and diagnose MIH (EAPD Criteria) as well as dental caries (ICDAS Index). Statistical analyses were performed with Person's Chi-square, Fisher's exact, and Mann-Whitney tests, and Poisson regression models were built. Statistical significance was set at an alpha-level of 0.05. The prevalence of MIH in our participants was 9.8%, with lesions being mostly of the mild form (65.2%) and affecting the first permanent molars but not the incisors in 54.2% of the children. Dental caries was observed in 88.1% of subjects. We observed a significant association between dental caries and the following variables: presence of MIH (p < 0.01; PR = 1.13), dental visit (p < 0.02; PR=0.92), and parents or legal guardians' education level (p < 0.05; PR = 1.07). A MIH diagnosis was also significantly associated with family income (p < 0.05; PR = 4.09). Children with MIH had more caries lesions on molar surfaces (p < 0.01; PR = 4.05). The prevalence of MIH was found to be moderate, based on previous studies, and the presence of enamel defect was associated with dental caries. The teeth most affected by MIH lesions were the first permanent molars.

Dental Fear in Children: Association with Dental Caries and Molar Incisor Hypomineralization.

The aim of this study was to investigate the prevalence of dental fear and to evaluate its association with dental caries and molar incisor hypomineralization (MIH) in schoolchildren aged 8-10 years from a municipality in Northeastern Brazil. Data from 466 students enrolled in urban public schools in a cross-sectional study were collected. Parents/guardians answered a questionnaire addressing sociodemographic characteristics, dental fear was measured by means of the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) and clinical examinations were performed by three calibrated examiners for diagnosis of dental caries, using the International Caries Detection & Assessment System - ICDAS II and a previously validated index for MIH. Descriptive data analysis was performed, and associations between dental fear, dental caries and MIH were analyzed using robust Poisson regression for complex samples (p<0,05). The prevalence of dental fear was 21.6%, and the mean total CFSS-DS score was 29.97 (CI 95%=29.05-30.89). In the multivariate adjusted model, the prevalence of dental fear was associated to family income (PR=1.78; CI 95%=1.02-3.08; p= 0.041). Monthly family income was associated with dental fear in children, whereas dental caries and MIH were not associated with dental fear.

Mental Health of Dentists during the COVID-19 Pandemic: A Critical Literature Review

The effects of the Coronavirus Disease 2019 (COVID-19) pandemic on the mental health of healthcare professionals has become a concern, particularly among those who are in close contact with infected patients, including dentists. The aim of this critical literature review was to analyze the possible implications of the COVID-19 pandemic on the mental health of dentists. This bibliographic search was carried out in the PubMed, Web of Science and Scopus databases, using the following search keywords "Psychiatry OR anxiety OR fear OR depression OR psychological distress OR mental health" AND "COVID-19 OR SARS-CoV-2" AND "Dentists OR dental practice. Original research publications that included data on the mental health status of dentists during the COVID-19 pandemic were included. Data were tabulated in Microsoft Excel 2016 for Windows and descriptively presented. Eleven publications were eligible for this review. All studies had cross-sectional design. Most of them used questionnaires created by study researchers (81.8%) and were carried out in Italy (45.5%). The number of participants ranged from 14 to 1,500. Effects on the mental health of dentists during the COVID-19 pandemic were observed, regarding fear of contamination, anxiety, concerns, stress, depression, job insecurity, subjective overload, perceived risk and feelings and emotions. It was concluded that the COVID-19 pandemic had negative impact on the mental health of dentists, with high prevalence of fear, anxiety and concern, among other psychological symptoms.

Introdução: as escovas dentais possuem como principal função a limpeza dos tecidos bucais. Objetivo: analisar as características micro e macroscópicas de escovas dentais de uso infantil e adulto. Metodologia: foram selecionadas 11 escovas dentais (cinco de uso infantil e seis de uso adulto). Dois pesquisadores treinados analisaram aspectos microcoscópicos e macroscópicos, de acordo com os parâmetros da Portaria n° 97/SVS (ANVISA). Os dados foram tabulados e analisados utilizando-se o Microsoft Excel, sendo apresentados por meio de estatística descritiva. Resultados: foram encontradas cerdas arredondadas em 40% das escovas de uso infantil e em 66,7% de uso adulto, com farpas em 60% das escovas de uso infantil e em 50% de uso adulto, com a parte ativa ovalada em 60% das escovas de uso infantil e em 50% de uso adulto e com as cerdas macias em 80% das escovas de uso infantil e em 50% de uso adulto. O comprimento e a largura da parte ativa das de uso infantil variaram de 19,14 a 25,03 mm e de 8,82 a 13,98 mm respectivamente, enquanto, nas de uso adulto, o comprimento variou de 25,77 a 37,02 mm e a largura de 12,57 a 15,40 mm. As escovas de uso infantil possuíam comprimento total entre 137,91 e 163,82 mm e as de uso adulto entre 180,08 mm e 195,42 mm. Conclusão: a maioria das escovas dentais analisadas não estão adequadas aos parâmetros estabelecidos na legislação brasileira, sendo essencial que o cirurgião-dentista oriente individualmente o paciente acerca de qual escova é a mais indicada.

Introduction: toothbrushes have the main function of cleaning the oral tissues. Objective: to analyze the micro and macroscopic characteristics of children's and adult's toothbrushes. Methodology: eleven toothbrushes were selected (five for children and six for adults). Two trained researchers analyzed microscopic aspects and macroscopic aspects of the brushes, according to the parameters of Ordinance Number 97/SVS (ANVISA). Data were tabulated and analyzed by using Microsoft Excel and were presented by using descriptive statistics. Results: rounded bristles were found in 40% of the children's brushes and 66.7% of the adult, with barbs in 60% of the children's brushes and 50% of the adult, with the active part oval in 60% of the children's brushes and 50% adult brushes and soft bristles on 80% of the children's brushes and 50% of the adult. The length and width of the active part of the children's brushes ranged from 19.14 to 25.03 mm and from 8.82 to 13.98 mm respectively, while the adult brushes ranged from 25.77 to 37.02 mm in length and from 12.57 to 15.40 mm in width. The children's brushes had a total length between 137.91 and 163.82 mm and the adult brushes were between 180.08 mm and 195.42 mm. Conclusion: most of the toothbrushes analyzed are not adequate by the parameters established by the Brazilian legislation, so it is essential that the dentist individually guide the patient as to which toothbrush is the most suitable.

Conclusion: The clinical trials developed by brazilian resourchers toward dental caries theme are mostly developed on children, predominating the parallel design and therapeutic purpose. There is large variability on sample numbers, with low use of placebo groups.

Hipomineralização molar-incisivo: etiologia, características clínicas e tratamento / Molar incisor hypomineralization: etiology, clinical characteristics and treatment

Introdução: a Hipomineralização Molar-Incisivo (HMI) é um defeito de desenvolvimento do esmalte dentário que afeta de um até todos os primeiros molares permanentes, podendo estar presente nos incisivos permanentes. Objetivo: revisar a literatura sobre a HMI objetivando proporcionar informações ao cirurgião-dentista que realiza atendimento infantil sobre o diagnóstico, características clínicas e tratamento. Metodologia: revisão integrativa da literatura, sendo utilizado as bases de dados LILACS, PubMed, Web of Science e Scopus. Foram usadas as palavras-chaves "Hipoplasia do Esmalte Dentário/Dental Enamel Hypoplasia" e " Hipomineralização Molar-Incisivo/Molar Incisor Hypomineralization". Resultados: fatores etiológicos associados a complicações pré, peri e pós-natais, ambientais e genéticos têm sido evidenciados e a prevalência de HMI mostra-se variada entre as populações. Apresenta-se como manchas opacas bem delimitadas e, com o aumento da gravidade, ocorre a perda do esmalte resultando em fratura, destruição coronária e indicação de exodontia. As fraturas pós-eruptivas atuam como áreas de retenção de biofilme, o que facilita seu acúmulo e aumenta a susceptibilidade à cárie dentária. A Academia Europeia de Odontopediatria (EAPD) estabeleceu critérios que facilitam o diagnóstico deste agravo por meio de pesquisas epidemiológicas. As medidas terapêuticas são direcionadas de acordo com a gravidade da lesão. Conclusão: a HMI deve receber adequada atenção do cirurgião-dentista em função das consequências clínicas e estéticas que acarreta ao paciente, interferindo negativamente na sua qualidade de vida nos casos mais graves. Novas pesquisas são necessárias com a finalidade de expandir o conhecimento acerca da HMI, objetivando ofertar ao paciente o correto diagnóstico e a melhor opção terapêutica.

ntroduction: molar Incisor Hypomineralization (HMI) is a developmental defects of enamel that affects from one to all first permanent molars and also permanent incisors. Aim: to review the literature with the aim of providing information to the pediatric dentist about the diagnosis, clinical characteristics and treatment of HMI. Methodology: integrative literature review, using the LILACS, PubMed, Web of Science and Scopus databases. The keywords "Hipoplasia do Esmalte Dentário/Dental Enamel Hypoplasia" and "Hipomineralização Molar-Incisivo/Molar Incisor Hypomineralization" were used. Results: etiologic factors are associated with prenatal and postnatal factors, environmental and genetic complications. The prevalence of HMI is varied among the populations. It's clinically characterized as delimited opaque spots. With increasing severity, can occurs enamel loss, fracture, coronary destruction and indication of exodontia. Post-eruptive fractures act as areas of biofilm retention, which facilitates their accumulation and increases susceptibility to dental caries. European Academy of Pediatric Dentistry (EAPD) has established criteria that facilitate diagnosis of HMI in epidemiological research. Therapeutic measures are indicated according to the severity of the lesion. Conclusion: MIH should receive adequate attention from the dentist due to its clinical and aesthetic consequences, interfering negatively in quality of life of patients in the most severe cases.
