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.

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.

Considerations on endodontic care in times of SARS CoV-2 pandemic / Considerações sobre o atendimento endodôntico em tempos de pandemia SARS CoV-2

ABSTRACT The severe acute respiratory syndrome of the new coronavirus, SARS CoV-2, which became a pandemic, was first reported in Wuhan, Hubei, China, in December 2019. It can cause mild symptoms, but in some cases, it can cause serious complications, leading to death. The disease spreads through aerosol droplets and has an estimated incubation period between 2 and 14 days (a period in which the patient has high potential to infect other people). Endodontists have a high risk of exposure to COVID-19 when compared to other health professionals, since most of the work involves the generation of aerosols and care for patients in emergency situations, such as symptomatic irreversible pulpitis, symptomatic apical periodontitis, acute apical abscess and traumatic dental injuries, is imperative. Thus, this critical review addresses considerations about endodontic care in times of pandemic, whose emergencies imply a real need for treatment, as well as the care that must be adopted to minimize risks for both professionals and patients who seek the resolution of their clinical pain conditions.

RESUMO A síndrome respiratória aguda grave do novo coronavírus, SARS CoV-2, que se tornou uma pandemia, foi relatada pela primeira vez em Wuhan, Hubei, China em dezembro 2019. Pode acarretar sintomas leves, porém em alguns casos pode provocar graves complicações levando o indivíduo ao óbito. A doença se espalha através de gotículas de aerossol e tem um período de incubação do coronavírus estimado entre 2 e 14 dias (período este no qual o paciente tem alto potencial de infectar outras pessoas). Os endodontistas apresentam alto risco de exposição ao COVID-19 quando comparado a outros profissionais de saúde, pois a maior parte do trabalho envolve a geração de aerossóis e os atendimentos a pacientes em situações emergentes, como pulpite irreversível sintomática, periodontite apical sintomática, abscesso apical agudo e lesões dentárias traumáticas são imperativos. Dessa forma, essa revisão crítica aborda considerações sobre o atendimento endodôntico, nesta época de pandemia, cujas emergências imprimem necessidade real de tratamento, bem como os cuidados que devem ser adotados visando minimizar riscos tanto para o profissional quanto para os pacientes que buscam a resolução dos seus quadros clínicos de dor.

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.

Use of Medicines by Infants with Microcephaly Caused by Congenital Zika Virus Infection and Implications to Oral Health

Abstract Objective: To analyze the use of continued-use medications by Brazilian children with microcephaly caused by Congenital Zika Virus Infection. Material and Methods: Cross-sectional study with 76 children of both genders. Information on age, use of continued-use medications, number and type of drugs used was collected. Data were analyzed using descriptive statistics. Results: Continued-use medications were used by 89.4% of the children, anticonvulsants / antiepileptics (88.1%), and those indicated for behavioral disorders (27.1%) were the most frequent. Sodium saccharin, sucrose, and sorbitol are the most common sugars in the composition of these drugs. Conclusion: The use of medicines is high, predominantly anticonvulsants and antiepileptics, which contain sugars in their composition. These drugs can lead to irreversible dental problems, such as tooth decay if proper oral hygiene is not present. Therefore, parents/guardians should be advised about adopting healthy oral hygiene habits after the administration of these drugs.

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.

Risk behavior for bulimia among adolescents / Comportamento de risco para bulimia em adolescentes

ABSTRACT Objective: To analyze the risk behavior for bulimia among female adolescents from public and private high schools. Methods: A cross-sectional study with a random sample of 850 female students aged 15-18 years was carried out in a city in northeastern Brazil, using the Bulimic Investigatory Test of Edinburgh (BITE) to assess the risk behavior for bulimia. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software and the Pearson's chi-square , Fisher's exact and robust Poisson regression tests, adopting the significance level of 5%. Results: Less than half of the sample (42.0%) showed standards of dietary risk and weight control practices; in 1.4% of the sample, bulimia signs were already installed. Fear of gaining weight was reported by 62.8% of the subjects. Risk practices were lower among students from public schools; (Odds Ratio - OR - 0.82; confidence interval of 95% - 95%CI - 0.69-0.97). Among restrictive practices, fasting for a whole day was the most applied (29.9% of the students). Among individuals who were at risk situation, almost half believed to have normal eating habits (prevalence ratio - PR - 0.42; 95%CI 0.36-0.49). Individuals who consider their eating habits normal, who are afraid of gaining weight, those who seek emotional comfort in food and follow strict diets had higher risk for bulimia (p<0.05). Conclusions: The number of female adolescent students with risk behavior practices for bulimia is high, and the frequency of those unaware of this situation is also very high. Risk situations emerge as a collective health problem, and individuals from private schools were more likely to be in this situation.

RESUMO Objetivo: Analisar comportamentos de risco para bulimia em adolescentes do sexo feminino de escolas públicas e particulares. Métodos: Estudo transversal com amostra aleatória de 850 estudantes do sexo feminino, com idades entre 15 e 18 anos, realizado em cidade do Nordeste do Brasil, utilizando o Bulimic Investigatory Test of Edinburgh (BITE) para avaliar comportamentos de risco para transtornos alimentares. Os dados foram analisados utilizando o teste do qui-quadrado de Pearson, o teste exato de Fisher e a regressão de Poisson, com o software Statistical Package for the Social Sciences (SPSS), adotando o nível de significância de p<0,05. Resultados: Da amostra estudada, 42,0% apresentou padrões de risco e práticas de dieta e controle de peso e 1,4% já apresentava sinais de bulimia instalados. O medo de ganhar peso foi relatado por 62,8% das adolescentes. As práticas de risco foram menos frequentes em estudantes de escolas públicas (Odds Ratio - OR - 0,82; intervalo de confiança de 95% - IC95% - 0,69-0,97). Entre as práticas restritivas, jejum por um dia inteiro foi o mais aplicado pelas participantes (29,9%). Entre os indivíduos com situação de risco, quase metade acreditava ter hábitos alimentares normais (razão de prevalência - RP - 0,42; IC95% 0,36-0,49). Estudantes que consideram seus hábitos alimentares normais, que têm medo de ganhar peso, que procuram conforto emocional em alimentos e seguem dietas rigorosas tiveram maior risco para bulimia (p<0,05). Conclusões: O número de estudantes com práticas de comportamento de risco para bulimia é alto, e o número daquelas que desconhecem essa situação também é muito alto. As situações de risco emergem como problemas de saúde coletiva, e indivíduos de escolas particulares são mais propensos a apresentar transtornos alimentares.

In Situ Effect of Intra-Oral Application of Pastes Containing CPP-ACP or CPP-ACPF Against Initial Enamel Erosion

Objective: To evaluate in situ the effect of toothpastes containing casein phosphopeptide - amorphous calcium phosphate (CPP-ACP) and casein phosphopeptide-amorphous calcium phosphate associated to fluoride (CPP-ACPF) on initial erosion prevention. Material and Methods: Bovine enamel blocks (n = 192) were randomly assigned into 4 phases according to the baseline surface hardness: GI: CPP-ACP Paste (MI Paste™), GII: CPP-ACPF Paste (MI Paste Plus™), GIII: Fluoridated paste and GIV: Placebo Paste. In each of the 4 crossover phases, twelve volunteers wore intraoral palatal appliances containing 4 enamel blocks for 2 hours, then the tested treatments were applied intraorally (3 min) and the appliance was maintained in the mouth for another 3 hours. After, the appliances were removed and immersed in hydrochloric acid (0.01 M, pH 2.3) for 30 seconds to promote erosive demineralization. The final surface hardness was evaluated and percentage of surface hardness loss was calculated. The data were analyzed by ANOVA and Tukey's test (α = 5%). Results: The application of CPP-ACP paste, independent of fluoride content, resulted in significant lower enamel hardness loss (GI: 9.26% ±3.48 and GII: 9.14% ±1.73) compared to NaF (GIII: 15.5% ± 3.94) and placebo (GIV: 16.7% ± 4.07) pastes, which did not show difference between them. Conclusion: The CPP-ACP pastes were able to reduce initial erosive demineralization in relation to fluoride and placebo pastes. Nevertheless the formulation of CPP-ACP with fluoride did not provide an additional benefit.

Craniofacial trauma in older adults victims of road traffic accidents: a cross-sectional study

Introduction: Among the determinant factors for the implant-supported prosthesis longevity is the exact and comprehensive process of impression which results is the passive prosthesis fitting. Objective: To compare the accuracy of transfer coping impression techniques with or without splinting, after the isolation of the factors associated to the passive fitting. Method: Based on the control group composed by an edentulous mandibular master model (self-cured acrylic resin) with four external hexagon parallel implants splinting with a metallic bar, four customized open trays were constructed with self-cured acrylic. Ten impressions were made with condensation silicone ( Xantopren ®), poured with type IV plaster ( Durone ®), and then divided into two groups: Group 1 (n=5) ­ non-splinting multi unit transfer copings; and Group 2 (n=5) ­ splinting multi unit transfer copings with a bar constructed with self-cured acrylic resin ( Palavit G ®) and dental floss, with the aid of an addition silicon mold ( Elite Double ® Zhermack) . Next, the bar was cut and splinted again. The ten transfer molds were measured at the center of the labial surface of each implant with the aid of Stereoscopic Magnifying Glass ( Physis ®) with x60 magnification. The results were tabulated and submitted to non-parametric statistics through Kruskal-Wallis test (p<0.05). Results: The means were: 22.44 µm (±7) for control group, 26.86 µm (±10) for direct splinting, and 24.70 µm (±13) for direct non-splinting technique. Conclusion: No statistically significant differences were found between the tested techniques.

Introdução: Entre os fatores determinantes para a longevidade de uma prótese implanto suportada, está o processo exato e meticuloso de moldagem dos implantes osseointegrados, implicando diretamente no assentamento passivo da prótese. Objetivo: Comparar a precisão das técnicas de moldagem com e sem união dos transferentes isolando os fatores que podem estar associados ao ajuste passivo. Métodos: A partir de um grupo controle composto por um modelo mestre (em resina acrílica quimicamente ativada) mandibular desdentado com quatro implantes de conexão externa posicionados paralelamente e unidos por uma barra metálica. Foram confeccionadas dez moldeiras em resina acrílica quimicamente ativada (todas abertas). Dez impressões foram feitas com silicone de condensação Xantopren ®, e vertidas com gesso tipo IV, Durone ®, divididas em dois grupos: Grupo 1 (n=5) ­ Pilares multi unit não unidos e Grupo 2 (n=5) ­ Pilares multi unit unidos por uma barra confeccionada com fio dental e resina acrílica autopolimerizável, Palavit G ®, através de um molde de silicone de adição, Elite Double ® Zhermack . Em seguida, a barra foi seccionada e reunida. Os dez modelos de transferência foram mensurados no centro da face vestibular de cada um dos implantes através de uma lupa estereoscópica ( Physis ®) com ampliação de 60 vezes. Os resultados foram tabulados e submetidos à análise estatística não paramétrica, teste Kruskal-Wallis (p<0,05). Resultados: As médias aritméticas encontradas foram de 22,44 µm (±7) para grupo controle, 26,86 µm (±10) para técnica direta com esplintagem e 24,70 µm (±13) para técnica direta sem esplintagem. Conclusão: Não foi identificado diferenças estatísticas significantes entre as técnicas experimentadas.

ABSTRACT Objective To assess oral hygiene habits, and prevalence of dental caries and erosion in adolescents of Campina Grande, Paraíba, Brazil. Methods Cross-sectional study with random cluster sampling involving 201 15-year-old schoolchildren. Oral health habits were obtained through questionnaire, and socioeconomic data, by means of interviews. The DMFT index was adopted to determine the prevalence of caries and that proposed by O'Sullivan, to assess dental erosion. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 18. A 5% significance level was adopted. Results All subjects reported using toothbrush and toothpaste, 50.7% reported dental flossing, and association was found between sex and use of mouthwash (p <0.05). Regarding dental caries, the mean DMFT was 3.67 and 51.7% had DMFT lower than or equal to 3. For dental erosion, 18.4% of the sample had erosive lesions, predominantly enamel lesions (92%). Conclusion The use of dental floss was low and adolescents revealed unsatisfactory index. The DMF-T value was moderate and lower than that reported for the Brazilian age group. The prevalence of dental erosion was high, with predominance of enamel lesions.

Needlestick and Sharp Instruments Injuries among Brazilian Dentistry Students.

BACKGROUND: The occurrence of occupational accidents is common among students and dentists. The present study is aimed to evaluate the prevalence and characteristics of needlestick and sharp instrument injuries among dentistry students. MATERIALS AND METHODS: A documentary research was carried out with data being obtained from the analysis of 137 medical records of injuries caused by needlestick and sharp instruments occurring in the period from 2012 to 2016 and were analyzed regarding the characteristics of the victim (gender and age) and the accident (year, time, environment, and time interval between exposure and search for care). Data were organized in the Statistical Package for Social Sciences software version 18 and were presented through descriptive statistics. RESULTS: The occurrence of accidents was high (43.1%), with the predominance of female victims (66.1%) and aged up to 23 years (55.9%). The majority of events occurred in the afternoon (54.4%), in the clinical setting (70.7%), and in 75% of the cases, the search for care occurred within 2 h after exposure. CONCLUSION: Accidents with needlestick and sharp instruments have high frequency and involve mainly female students. They are more common in the afternoon and in the clinical setting and the time interval was between exposure and the search for care complied with recommendations of the Brazilian legislation.

Oral Health Status of Brazilian Workers of a Textile Industry

Objective: To evaluate the oral health status of Brazilian workers of a textile industry. Material and Methods: A cross-sectional study including 489 individuals of both sexes was performed. Data on gender, age, schooling, frequency of dentist visits and caries experience (DMFT) were collected by a single trained and calibrated examiner. Data were organized using the Statistical Package for Social Sciences (SPSS) software and presented through descriptive and inferential statistics (Poisson Regression Analysis). The significance level was 5%. Results: There was predominance of female workers (57.7%) aged 30-39 years (44.6%) and with 9-11 years of schooling (79.7%). Almost all of them had visited the dentist at least once in their lifetime (99.6%), and 66.8% had done so in the last 12 months. The mean DMFT value was 11.14 (± 5.64), with higher participation of filled (6.21) and missing components (4.03). There was a statistically significant association between DMFT values (≤ 11 and ≥ 12) and age group (p <0.001), as well as between schooling and number of missing (p <0.001) and decayed teeth (p < 0.001). Conclusion: The mean DMFT of Brazilian workers is high, with a tendency to increase the number of missing teeth as age increases. Schooling was associated with the number of missing and filled teeth.

Relationship between Risk Behavior for Eating Disorders and Dental Caries and Dental Erosion.

The aim of this study was to evaluate whether there is an association between risk behavior for eating disorders (EDs) and dental erosion and caries. A controlled cross-sectional study was conducted in Brazil, involving 850 randomly selected female adolescents. After evaluating risk behavior for eating disorders through the Bulimic Investigatory Test of Edinburgh, 12 adolescents were identified with severe risk behavior for EDs and matched to 48 adolescents without such risk. Dental examinations, anthropometric measurements, and eating habits and oral hygiene were performed. Adolescents with high severity eating disorder condition were not more likely to show dental caries (p = 0.329; OR = 2.2, 95% CI: 0.35-13.72) or dental erosion (p = 0.590; OR = 2.33; 95% CI: 0.56-9.70). Adolescents with high body mass index (BMI) were five times more likely to have high severity eating disorder condition (p = 0.031; OR = 5.1; 95% CI: 1.61-23.07).

Assessment of Oral Hygiene Level and Periodontal Condition in Brazilian Adolescents

Objective: To evaluate the oral hygiene level and periodontal condition of adolescents aged 15-19 years and socioeconomic factors. Material and Methods: Cross-sectional study with 630 adolescents from public schools randomly selected in the city of Campina Grande, Brazil. For data collection, a form containing socioeconomic variables and those related to oral hygiene was used. The oral hygiene level was measured through the Simplified Oral Hygiene Index (OHI-S) and periodontal condition was evaluated by the Community Periodontal Index (CPI). Data were descriptively and inferentially analyzed using the chi-square test, adopting significance level of 5%. Results: Adolescents were mostly females (59.5%), aged 16 years (32.4%), non-white (77.8%), with family income lower than US $ 612.00 (55.1%), with parental schooling of up to high school (50%). Periodontal condition showed no significant association with any of the socioeconomic factors (p> 0.05). All participants reported using toothbrush; however, the control of interproximal plaque with flossing was reported by only 44.1%, being higher among females (p = 0.028), and its use has been associated with periodontal status (p = 0.026). The oral hygiene level was satisfactory for 59.7% of adolescents, while CPI showed that only 1.6% of them had healthy periodontium and gingival bleeding (34.4%) and presence of dental calculus (37, 8%) were the most prevalent alterations. Conclusion: Adolescents showed satisfactory oral hygiene condition; however, there was a high prevalence of gingival bleeding and dental calculus. Periodontal condition was associated with flossing; however, association with socioeconomic factors was not observed.

Association Between Nutritional Status and Dental Caries in Brazilian Teenagers with and without Risk for Eating Disorders

Objective: To evaluate the relationship between nutritional status and dental caries in Brazilian female adolescents with and without behavioral risk for eating disorders. Material and Methods: Cross-sectional study involving 60 girls, 15 to18 years old, randomly selected from public and private schools. Risk behavior for eating disorder was assessed by the Bulimic Investigatory Test of Edinburgh, anthropometric measurements were taken to calculate the body mass index, dental examinations were performed to verify the caries experience and a questionnaire to collect sociodemographic data was applied. Data were analyzed descriptively and analytically using the Statistical Package for the Social Sciences 18.0 software. The level of statistical significance was set at 5%, with a 95% confidence interval. Results: Most of the girls studied in public school (75,0%), had no partner (95,0%) and had a monthly family income above the minimum wage (63,3%). The prevalence of dental caries was high (86.7%). The most used practice for weight loss was the act of purge (18.3%). There was no statistically significant association between dental caries and Body Mass Index (p=0,655), however, it was observed that adolescents with high Body Mass Index had a higher risk for Eating Disorders (p<0,05). Conclusion: The nutritional status was not associated with dental caries, however the monitoring of girls with high Body Mass Indexis important due to the increased risk of eating disorders.
