RESUMO

The aim of this study was to establish and compare the prevalence and severity of erosive tooth wear (ETW) in children with and without erosive esophagitis. Children aged 5-12 years, scheduled for upper digestive endoscopy at the Pediatric Gastroenterology Service of the Children's Hospital Santo Antonio, Porto Alegre, Brazil, were eligible to participate in this study. Patients who presented erosive esophagitis at endoscopy were defined as gastroesophageal reflux disease (GERD) carriers, and the severity was described according to the Los Angeles classification. The oral cavity examination was performed by a trained and calibrated dentist and ETW was classified using the Basic Erosive Wear Examination (BEWE) index. Parents/guardians answered a questionnaire about the patients' diets and frequency of consumption of acidic foods and beverages. A total of 110 children were included in the study. Erosive esophagitis was observed in 24 patients (21.8%) and all of them (100%) presented ETW, showing a statistically significant association between these 2 conditions (p < 0.05). Among children who did not present with erosive esophagitis (n = 86), 54 (64.3%) had an ETW risk level of none according to their BEWE scores (0-2). The results of this study showed a statistically significant association between erosive esophagitis and ETW, thus it can be concluded that it is important to recognize groups at risk of ETW and act together with medical professionals to ensure adequate oral health for these patients.

RESUMO

Amelogenesis imperfecta (AI) is a rare hereditary condition characterized by abnormal enamel formation and increased tooth sensitivity. There are no defined therapeutic recommendations for tooth sensitivity in patients with AI. The aim of the present case report of a 5-year-old girl with AI is to describe the use of cyanoacrylate as a desensitizing agent on the patient's permanent molars and report the impact of this treatment on her oral health-related quality of life (OHRQoL). After 4 sodium fluoride varnish applications were unsuccessful in relieving sensitivity affecting the molars, cyanoacrylate was applied 5 times (at intervals of 7, 15, 30, and 180 days after the first application). Pain scores were recorded on a visual analog scale before and after each intervention, and the OHRQoL was measured using a questionnaire (Early Childhood Oral Health Impact Scale [ECOHIS]) administered prior to the first cyanoacrylate application and on the last day of the protocol. In this patient, cyanoacrylate seemed to be effective at decreasing tooth sensitivity in immature permanent molars affected by AI, as demonstrated by reductions in the frequency of complaints of dental pain, difficulty in drinking cold beverages, and difficulty in eating some foods.

RESUMO

Purpose: Erosive tooth wear often leads to surface loss requiring restoration of primary teeth with adhesive materials. The purpose of this study was to evaluate the microshear bond strength (µSBS) of different adhesive systems to sound and eroded primary enamel and dentin surfaces. Methods: Half of the samples underwent erosion (immersion in Coca-Cola for one minute five times over five days) and abrasion cycles (brushing with an electric toothbrush, fluoride toothpaste slurry, for one minute at 250 g load). Samples were divided into adhesive groups (n equals 12): Adper Single Bond 2 (etch-and-rinse); Single Bond Universal (self-etch); Optibond FL (etch-and-rinse with fluoride); and Bond-Force (self-etch with fluoride). Resin composite was bonded on sample surfaces and subjected to µSBS test. Data were analyzed by two-way analysis of variance, Tukey test, and chi-square test (P<0.05). The failure mode was determined using a stereomicroscope under 20X magnification. Results: No difference was found between the eroded and sound enamel and dentin (P≥ 0.05) on µSBS test. The failure mode evaluation showed significant differences between sound and eroded dentin (P=0.003) but no difference among the adhesives (P=0.177). Conclusions: Micro-shear bond strength in primary enamel and dentin was not affected by erosion/abrasion or type of adhesive system.

RESUMO

Abstract Objective: To measure the influence of oral health literacy (OHL) level in the improvement of knowledge about traumatic dental injuries (TDI) after an educational intervention. Material and Methods: A total of 257 parents of children aged 0-12 years had their OHL level evaluated (BREALD-30). A leaflet with information about how to respond to TDI Emergency was developed and delivered to the parents. A questionnaire about attitudes towards TDI was administered before (TDIQ1) and after (TDIQ2) parents read the educational leaflet. The hypotheses were evaluated by non-parametric tests, correlation analysis and logistic regression. Results: The mean OHL score was 21.6. The means of correct answers in TDIQ1 were 5.5 and 5.9 (p = 0.066) and in TDIQ2 were 6.6 and 7.7 (p=0.003) between the groups with inadequate and marginal/adequate OHL, respectively. In the logistic regression, the total score of BREALD-30 and the maximum number of correct answers in TDIQ2 maintained statistical association when adjusted for schooling, gender, age of the parents, family income and the number of correct answers in the first application of the questionnaire. Conclusion: The level of OHL influenced the improvement of parents' knowledge about emergency care in cases of TDI in children from an educational intervention using a leaflet, and this intervention was more effective for parents with adequate OHL.

RESUMO

AIM: To evaluate the erosive preventive effect of toothpastes in permanent (PT) and deciduous teeth (dt). DESIGN: Enamel samples were divided into five groups (n = 20): G1: placebo toothpaste; G2: NaF toothpaste; G3: AmF-NaF-SnCl2 anti-erosion toothpaste; G4: SnF2-toothpaste; and G5: NaF anti-erosion toothpaste for children. The samples were exposed to five erosion-abrasion cycles (artificial saliva incubation; 3 min in 1% citric acid; 2 min in slurry, toothbrush abrasion, 50 strokes, 200 g). Surface microhardness (SMH), surface specular reflection intensity (SRI), and cumulative surface loss (CSL) were measured. Comparisons among toothpastes were evaluated using Kruskal-Wallis tests and comparisons between PT and dt were evaluated using Wilcoxon's rank sum test. RESULTS: G1 exhibited significantly lower SMH values in PT than the other toothpastes (p < 0.05), with no significant differences among the others groups. In dt, G1 and G4 exhibited significantly different values than the other groups (p < 0.05). G4 exhibited lower values of SRI in both types of teeth. Deciduous teeth presented significantly higher SRI than PT (p < 0.05), except for G3. Deciduous teeth generally presented higher CSL than PT, except for G3. CONCLUSIONS: Deciduous teeth were more prone to mineral loss than permanent teeth. G5 exhibited better efficacy for both teeth, while G3 exhibited a better preventive effect only for deciduous teeth. CLINICAL RELEVANCE: Erosive tooth wear prevalence in children is growing and deciduous teeth are more susceptible than permanent teeth. Considering this, it is important to know the preventive effect of different toothpastes in an initial erosion-abrasion model.

RESUMO

Introduction: Erosive tooth wear (ETW) is defined as a chemical-mechanical process leading to the cumulative loss of hard dental tissue without the involvement of bacteria. Objective: to give to clinicians an overview about most important ETW topics. Data source: main scientific data base (PubMed, Lilacs) in the last 10 years, with the keywords: dental erosion, diagnosis and prevention. Classical articles were selected for the realization of an integrative literature review. Data synthesis : the prevalence of ETW has been reported to range from 10% to 80% in children and 4% to 82% in adults. The management of ETW should include early diagnosis, the evaluation of different etiological factors, risk identification and the proposal of preventive measures to avoid the progression of the condition. These measures include fluoride exposure, use of low abrasive toothpastes, clinical monitoring, and in more severe cases sealant application and restorations. Patients suffering from eating disorders with purging behaviour and gastroesophageal reflux disease are considered the most important risk groups. Conclusion : Clinicians should be aware of this condition with growing prevalence, once substance loss is an irreversible condition, providing prompt preventive measures during the early stages that are essential to reduce ETW.


Introdução: O Desgaste Dentário Erosivo é definido como um processo químico- mecânico que leva a uma perda cumulativa de tecido dentário duro, sem que ocorra o envolvimento de bactérias. Objetivo : atualizar os cirurgiões-dentistas sobre os principais tópicos a respeito do Desgaste Dentário Erosivo. Fonte de dados: principais bases científicas (PubMed, Lilacs) nos últimos 10 anos, com as palavras-chave: erosão dentária, diagnóstico e prevenção. Foram selecionados os artigos clássicos sobre o tema para a realização da revisão integrativa de literatura. Síntese de dados : A prevalência de Desgaste Dentário Erosivo tem sido reportada na literatura em porcentagens que variam de 10% a 80% em crianças e de 4% a 82% em adultos. A abordagem clínica do Desgaste Dentário Erosivo deve incluir um diagnóstico precoce, a avaliação dos diferentes fatores etiológicos, a identificação do risco e a proposta de medidas preventivas para retardar a progressão dessa condição. Essas medidas incluem a aplicação de fluoretos, o uso de dentifrícios com baixa abrasividade, monitoramento clínico e, em casos mais graves, a aplicação de selantes e procedimentos restauradores. Pacientes diagnosticados com transtornos alimentares ou com refluxo gastroesofágico são considerados um dos grupos de risco mais importantes para o desenvolvimento dessa condição. Conclusão: Os clínicos devem estar atentos a essa condição de prevalência crescente, uma vez que a perda de estrutura dentária é irreversível, promovendo medidas preventivas eficazes, desde os estágios iniciais, contribuindo assim para o controle e redução do Desgaste Dentário Erosivo entre seus pacientes.

RESUMO

BACKGROUND: Little is known about fluoride toothpastes effect on primary teeth submitted to erosive tooth wear. OBJECTIVES: To evaluate the preventive effect of different toothpastes on surface loss (SL) after severe erosion/abrasion model and to compare this effect between permanent (PT) and primary teeth (pt). DESIGN: Enamel samples were randomly divided according toothpastes groups (n = 17). G1: placebo; G2: NaF; G3: AmF-NaF-SnCl2 anti-erosion; G4: SnF2 ; and G5: NaF anti-erosion for children. Samples were incubated in artificial saliva (1 hour), submitted to erosive challenge (3 minutes; 1% citric acid; pH3.6; at 25°C) and to toothbrush abrasion (2 minutes slurry immersion; 50 strokes; 200 g) during 30 cycles. Surface loss (µm; mean ± SD) was quantified by contactless profilometry. The effects of the two covariables "tooth" and "toothpaste" were analysed by non-parametric ANOVA, variables with significant effects were tested by Wilcoxon tests. RESULTS: pt showed significantly higher surface loss than PT in all groups (P < 0.001). The mean values of SL of each group were: G1 PT 18.18(±3.98), pt 25.65(±9.21); G2 PT 14.76(±2.82), pt 18.11(±3.92); G3 PT 12.62(±5.29), pt 15.61(±6.70); G4 PT 17.12(±2.24), pt 23.41(±7.9); G5 PT 13.24(±1.29), pt 18.28(±8.96). CONCLUSIONS: In permanent teeth, G3 showed the best preventive effect. In primary teeth, G1, G3, and G5 showed similar effect.

RESUMO

To evaluate the effect of erosive challenges on the tooth- restoration interface of deciduous teeth treated with different adhesive protocols. Deciduous molars were cut mesiodistally, then embedded, abraded and polished (n=80). Samples were randomly divided according to the adhesive system used into: G1 (Adper Single Bond2®, etch-and-rinse), G2 (Universal Single Bond®, self-etching), G3 (OptibondFL®, etch-and-rinse with Fluoride) and G4 (BondForce®, self-etching with Fluoride). After standardized cavity preparation (2 mm diameter x 2 mm depth), adhesive systems were applied and samples were restored (composite resin Z350®). Half of the samples were exposed to erosive/abrasive cycles (n = 10, each adhesive group), and the other half (control group; n = 10) remained immersed in artificial saliva. For microleakage analysis, samples were submersed in methylene blue and analyzed at 40x magnifications. Cross-sectional microhardness (CSMH) was carried out (50 g/5 s) at 25 µm, 50 µm, and 100 µm from the eroded surface and at 25 µm, 75 µm, and 125 µm from the enamel bond interface. Regarding microleakage, 7.5% of the samples showed no dye infiltration, 30% showed dye infiltration only at the enamel interface, and 62.5% showed dye infiltration through the dentin-enamel junction, with no difference between groups (p≥0.05). No significant difference was observed in CSMH at different depths (two-way ANOVA, p≥0.05). We did not observe significant changes in microleakage or CSMH after erosive/abrasive challenges in deciduous teeth treated with different adhesive protocols (etch-and-rinse and self-etching adhesives, with and without fluoride).

RESUMO

The aim of the study was to compare surface loss values after erosion-abrasion cycles obtained with modified surface microhardness measurement (mSMH), focus variation 3D microscopy (FVM) and contact stylus profilometry (CSP). We cut human molars into buccal and lingual halves, embedded them in resin and ground 200 µm of enamel away. The resulting surfaces were polished. To maintain a reference area, we applied Block-Out resin to partly cover the enamel surface. The samples were incubated in artificial saliva (37°C; 1 h), then rinsed in deionized water (10 s) and dried with oil-free air (5 s). We immersed the specimens individually in 30 mL citric acid (1%, pH 3.6) for 2 min (25°C, 70 rpm dynamic conditions) before brushing them (50 strokes, 200 g) in an automatic brushing machine with toothpaste-slurry. We calculated the surface loss as per mSMH, by re-measuring the length of the same six indentations made before the abrasive challenge. The experiment consisted of five experimental groups that received between 2 and 10 erosion-abrasion cycles. Each group contained 15 specimens and samples in groups 1, 2, 3, 4 and 5 underwent a total of 2, 4, 6, 8 and 10 cycles, respectively. The resin was removed from the reference area in one piece under 10× magnification and the FVM and CSP were performed. Agreement between the methods was calculated with the intraclass correlation coefficient (ICC) and depicted in Bland-Altman plots. All methods presented a linear pattern of surface loss measurements throughout the experiment, leading overall to a strong, statistically significant correlation between the methods (ICC = 0.85; p<0.001). So, despite the different surface loss values, all methods presented consistent results for surface loss measurement.

RESUMO

In this study, we analyzed a newly developed optical reflectometer for measuring erosive tooth wear (ETW) in vitro. Three examiners independently assessed the labial surface of 80 deciduous canines and 75 permanent incisors. One examiner performed visual examinations (BEWE), and the other two used the optical pen-size reflectometer to measure surface reflection intensity (SRI) on the same labial surfaces. The examinations were made in duplicate with at least 1 week interval. Intra- and inter-rater agreements were calculated using weighted kappa analysis for BEWE, and intra-class correlation coefficients (ICC) as well as Bland-Altman plots for SRI. The teeth were separated into without (BEWE 0) or with (BEWE 1-3) ETW, and SRI cut-off points were calculated. Intra-rater agreement for the visual examination was 0.46 and 0.82 for deciduous and permanent teeth, respectively. Inter-rater and intra-rater agreement for SRI were good (ICC > 0.7; p < 0.001). SRI measurements produced high specificity values for deciduous and permanent teeth (≥0.74 and ≥ 0.84, respectively), and lower sensitivity values (≥0.37 and ≥ 0.64, respectively), but permanent teeth had generally higher SRI values (p < 0.05). We observed a significant association between BEWE and SRI (p < 0.05). The optical pen-size reflectometer was able to adequately differentiate ETW on permanent teeth, with highly reliable and reproducible measurements, but ETW on deciduous teeth was less accurately differentiated. The reflectometer is a good candidate for clinical research.

O tratamento da hipomineralização molar-incisivo dependerá da gravidade do dente afetado, abrangendo desde medidas preventivas até procedimentos restauradores complexos. Objetivos: Relatar um caso de um paciente infantil, 7 anos, gênero feminino, diagnosticada com HMI. Além, disso, descrever a abordagem terapêutica, tratamento restaurador e acompanhamento de 28 meses. Conclusão: Pacientes com hipomineralização molar-incisivo necessitam de acompanhamento longitudinal para prevenir perda de estrutura dentária e manutenção do tratamento restaurador.


Introduction: Molar incisor hypomineralization (MIH) is defined as the enamel dysplasia that affects one or more first permanent molars and frequently permanent incisors. These patients have several oral health problems that may include increased tooth wear, loss of enamel, higher susceptibility to dental caries and tooth sensitivity. The treatment of molar incisor hypomine-ralization depends on the severity of the affected teeth, including preventive measures as well as extensive restorative procedures. Objectives: To present a case report of a patient, female, diagnosed at 7 years old with MIH and to describe restorative procedures with a 28-months follow-up period. Conclusion: MIH Patients require longitudinal follow-up to prevent loss of tooth structure and maintenance of restorative treatment.

RESUMO

PURPOSE: The aim of the present study was to compare trait anxiety and dental anxiety among children, adolescents and their parents. MATERIALS AND METHODS: A cross-sectional study was conducted involving 100 patients from the Pediatric Dentistry Clinic of the Federal University of Parana (Brazil) between the ages of 8 and 17 years (mean age: 10.3; standard deviation: 2.03) and their parents, who responded to Corah's Dental Anxiety Scale (DAS) and the Trait Anxiety Scale. The data were analyzed using the Mann-Whitney test, analysis of variance and both Pearson's and Spearman's correlation coefficients. RESULTS: Ninety percent of children and adolescents and 76% of the parents had moderate anxiety based on the DAS score. Seventy-four percent of children and adolescents and 72% of the parents had moderate anxiety based on the Trait Anxiety Scale score. The trait anxiety and dental anxiety scores were correlated among the adults (rs = 0.64) and children (r = 0.52), whereas no correlation between scores was found among the adolescents. Associations were also found between children's trait anxiety and the dental and trait anxiety of their parents (both r = 0.43). CONCLUSIONS: A moderate degree of dental anxiety was prevalent among the children, adolescents and parents who took part in this investigation, with correlations demonstrated between some trait anxiety and dental anxiety scores.

RESUMO

The aim of the present study was to analyze dental research trends in Brazil over the past nine years. All abstracts presented at the 26th Annual Meeting of the Brazilian Society for Dental Research in 2009 (n = 2648) were classified based on field of knowledge, home institution and geographic region. Data were compared with those previously published based on abstracts presented at various meetings. Between 2001 and 2006, five fields of knowledge had a greater than 10% representation among the total number of studies. These fields included restorative dentistry/dental materials (RD/DM), periodontics, endodontics, pediatric dentistry and population-based oral health. In 2009, only RD/DM maintained a greater than 10% proportion of meeting abstracts, and basic fields comprised the second position among those fields with greater representation (9.8%). The majority of research studies were performed at public institutions, and the number of abstracts per state increased significantly in 2009 (Wilcoxon test, p < 0.001). The southeastern region of Brazil submitted the greatest number of abstracts; however, other regions also demonstrated increased participation in research (11%). The percentage distribution of abstracts between states remained constant (Wilcoxon test, p = 0.255; r s = 0.873). The results of the present study suggest a slight shift in the scientific research profile in Brazilian dentistry: fields related to professional disciplines have declined in relative research participation, while increasing interest has been observed in basic fields and new specialties.

RESUMO

OBJETIVO: Relatar o caso de um paciente com tetralogia de Fallot e sua condição bucal. DESCRIÇÃO DO CASO: Paciente do gênero masculino atendido no Curso de Especialização em Odontopediatria da Escola de Aperfeiçoamento Profissional da Associação Brasileira de Odontologia da seção Paraná dos cinco aos sete anos de idade. O exame clínico intrabucal inicial revelou quadro de cárie severa da infância. Durante o acompanhamento, verificou-se a erupção dos primeiros molares permanentes com a presença de defeitos de desenvolvimento de esmalte e perda de estrutura dental. À anamnese, a mãe relatou que o paciente foi portador de tetralogia de Fallot e que a cirurgia corretora foi realizada com um ano e 11 meses de idade. COMENTÁRIOS: A formação do esmalte dental dos primeiros molares permanentes ocorre a partir do primeiro mês de vida e é finalizada entre dois e quatro anos de idade. Neste caso, tal etapa coincidiu com o período anterior à cirurgia para correção da tetralogia de Fallot, fato que pode ter interferido negativamente no processo de mineralização dos primeiros molares permanentes. Os defeitos de desenvolvimento do esmalte podem levar a perda de estrutura dental, favorecendo o aparecimento da cárie dentária. Dessa forma, o odontopediatra deve realizar um diagnóstico precoce dessas alterações e intervir preventivamente para evitar a perda de tais dentes. Uma anamnese bem detalhada e a maior interação entre pediatras e odontopediatras podem proporcionar melhor acompanhamento de crianças com fatores de risco para apresentar defeitos de desenvolvimento do esmalte dentário.


OBJECTIVE: To report a case of a child with tetralogy of Fallot and his oral conditions. CASE DESCRIPTION: A male patient was assisted at the Pediatric Dentristry Specialization Course of the Brazilian Dentistry Association in the State of Paraná, Brazil, from five to seven years old. At the first intrabucal examination, the child presented a severe caries disease. During their treatment, enamel developmental defects were detected in the first permanent molar tooth, with loss of enamel structure. His mother reported that the patient had a surgical correction of tetralogy of Fallot cardiac malformation when he was 23 months old. COMMENTS: The enamel development of the first molar starts in the first month of life and ends around two to four years old. In this patient, the period of mineralization of the first molar was coincident with the period prior to the surgical correction of the cardiac problem. Probably, the development of dental enamel was impaired by the systemic repercussion of this congenital anomaly. Enamel developmental defects can present loss of dental structure, increasing the risk of caries. Therefore, the pediatric dentists should diagnose dental enamel developmental defects early, in order to prevent serious damages to the teeth. A detailed anamnesis and a good interaction between pediatricians and pediatric dentists will provide a better follow-up of children at risk of having dental enamel developmental defects.
