ABSTRACT

Abstract This study was a randomized controlled clinical trial with two parallel arms and the objective was to compare the survival of resin modified glass ionomer (RMGIC) restorations in primary teeth using rubber dam or cotton roll isolation after a 30-month follow-up period. Ninety-two children (mean age 6.8 ± 1.37) and 200 primary molars with occlusal or occluso-proximal cavitated dentin caries lesions were randomly assigned into two groups: cotton rolls and rubber dam. All lesions were restored using RMGIC (RIVA Light Cure) after selective caries removal. Restorative failure and lesion arrestment were evaluated by two independent, trained, and calibrated examiners through clinical and radiographic examinations. The Kaplan-Meier test was used to assess the survival of restorations and Cox regression was used to assess the association of risk factors with restorative failure. There was no significant difference in survival rates between groups (p = 0.17). Older age (HR = 2.81 [95%CI: 1.47-5.44]) and higher rate of gingival bleeding (HR = 0.47 [95%CI: 0.23-0.99]) were associated with restorative failure. No patient had painful symptoms, pulp outcomes, or radiographic changes compatible with lesion progression. The use of rubber dam isolation did not increase the survival rate of occlusal and occluso-proximal restorations using RMGIC in primary molars after 30 months of follow-up. Since the survival is not influenced by the type of isolation, the professional can safely choose the appropriate technique for each case, considering his experience and preferences, as well as those of the patient.

ABSTRACT

A Prótese bucomaxilofacial (PBMF) é a especialidade da Odontologia que reabilita proteticamente pacientes com perda de estrutura na região da face. Entende-se por PBMFs aquelas utilizadas na reabilitação de pacientes que apresentam deformidades por etiologia congênita, traumática ou patológica. Objetivo: Avaliar retrospectivamente o perfil dos pacientes bem como as características das reabilitações protéticas realizadas em um Projeto de Extensão em Prótese Bucomaxilofacial de uma Universidade no sul do Brasil.Materiais e métodos:Foram analisados 90 prontuários de pacientes atendidos no período de agosto de 2017 a dezembro de 2018, e coletados os seguintes dados: gênero, cor/etnia, idade, etiologia da deformidade, tipo de prótese reabilitadora realizada e referenciamento do paciente ao Projeto. Resultados:Observou-se que pacientes do gênero masculino e cor branca foram os mais frequentemente reabilitados com a maioria dos tipos de prótese, com exceção da prótese nasal. A idade dos pacientes variou de 5 a 81 anos. A prótese ocular foi a mais confeccionada. A etiologia patológica foi a que mais exigiu tratamento reabilitador. Médicos e equipes hospitalares foram os que mais referenciaram pacientes para o Projeto de Extensão.Discussão: A maior prevalência de atendidos foi de pacientes do gênero masculino, etiologia patológica, com idade 60 anos ou mais, o que reforça a sobrevida das pessoas que são diagnosticadas com câncer e necessitam reabilitação bucomaxilofacial. Conclusão: A grande procura por atendimento no Projeto de Extensão em PBMF mostra uma carência desse serviço e poucas pesquisas para esclarecer o perfil do paciente que mais procura atendimento PBMF.


Bucomaxillofacial Prosthesis (BMFP) is a specialty of Dentistry that rehabilitates patients with loss of structure in the face region. BMFP are known to be used in the rehabilitation of patients who present deformities due to congenital, traumatic or pathological etiology. Aim:In retrospect, to assess the profile of patients, as well as the features of clinical cases of rehabilitations performed at the Buccomaxillofacial Prosthesis Extension Project, at the Faculty of Dentistry of the Universidade Federal do Rio Grande do Sul, UFRGS. Materials and methods:from August 2017 to December 2018, 90 charts were cataloged with the following data: gender, ethnicity, age, etiology of the deformity, type of rehabilitation prosthesis, how the patient came to the Project. Results:It was concluded that white male patients were the predominant group to be benefited with prosthesis. The age gap was from 5 to 81 years. Ocular prosthesis was the most prevalent one. The pathological etiology was the one that most required rehabilitation treatment. Doctors and hospital staff were the ones who most referred patients to the Project.Discussion:The prevalence of patients attended was male, pathological etiology, aged 60 years or more, which reinforces the survival of people who are diagnosed with cancer and need oral and maxillofacial rehabilitation. Conclusion:The great demand for care in the BMFP Extension Project shows a lack of this service and little research to clarify the profile of the patient who most seeks BMFP care.

ABSTRACT

Objective: this study aimed to evaluate knowledge and attitudes of professional wine tasters about erosive tooth wear. Material and Methods: two questionnaires were applied to 56 wine tasters during the 25th National Evaluation of Wines - Safra 2017 in Bento Gonçalves, Rio Grande do Sul. Descriptive data analysis and the Fisher's exact test were performed (p < 0.05). Results: for the analysis, 56 volunteers aged 25-76 years were included. Most of the volunteers reported attending dentist once a year (55.35%) and their teeth become sorer after ingesting liquids or acid foods (32.14%) over time. The majority (82.14%) believe wine tasting may have teeth effects and have already heard about erosive tooth wear (51.78%). However, when asked about symptomatology, more than half (53.57%) reported not to know. Brushing teeth immediately after ingesting something (37.5%) and increasing the brushing frequency (33.92%) were the most cited treatment options. The habit of using mouthwash solutions was significantly associated with the professionals age (p = 0.039). Conclusion: the volunteers reported a high intake of acid substances and, although most of them reported to consult dentist regularly and have already heard about erosive tooth wear, knowledge about this condition is still limited among these professionals. (AU)


Objetivo: o objetivo desse estudo foi avaliar o conhecimento e as atitudes de provadores de vinho profissionais relacionadas ao desgaste dentário erosivo. Material e Métodos: dois questionários foram aplicados a 56 provadores de vinho durante a 25ª Avaliação Nacional de Vinhos - Safra 2017 no município de Bento Gonçalves, Rio Grande do Sul. Foi realizada a análise descritiva dos dados e o teste Exato de Fisher (p < 0.05). Resultados: na análise foram incluídos 56 voluntários com idade entre 25 e 76 anos. A maioria dos voluntários relatou frequentar o dentista uma vez por ano (55,35%) e que seus dentes, com o passar do tempo, tornaram-se mais doloridos ao ingerir líquidos ou alimentos ácidos (32,14%). Mais da metade (82,14%) acreditam que as provas de vinho podem causar algum efeito sobre os dentes e já ouviram falar em desgaste dentário erosivo (51,78%). Porém, quando questionados sobre a sintomatologia, a maioria (53,57%) afirmou não ter conhecimento. Escovar os dentes imediatamente após ingerir algo (37,5%) e aumentar a frequência de escovação (33,92%) foram as opções mais compreendidas como tratamento. Utilizar soluções para bochecho esteve significativamente associado à idade dos profissionais (p=0,039). Conclusão: provadores de vinho profissionais relataram alta ingestão de substâncias ácidas e, embora a maioria consulte pelo menos uma vez por ano o dentista e já tenha ouvido falar a respeito do desgaste dentário erosivo, o conhecimento sobre essa condição ainda é limitado entre esses profissionais. (AU)

ABSTRACT

Abstract Dental Specialties Centers (CEOs) are clinics representing part of the secondary oral health care system of the Brazilian Unified Health System (SUS). Pediatric dentistry is not a requirement for service accreditation. However, the CEO of the Federal University of Rio Grande do Sul (CEO-UFRGS) has provided dental care for children aged 3-11 years since 2017. The utilization rates of health services are influenced by absenteeism. Therefore, evaluation of absences for dental appointments is of primary importance. This study aimed to evaluate referral characteristics, absenteeism, and resolubility of pediatric dentistry appointments at the CEO-UFRGS. This retrospective cross-sectional study was conducted at the Dental Teaching Hospital of the university and analyzed secondary data from referrals and medical records. From August 2017 to December 2019, 167 referrals and 96 medical records were reviewed, from which data of individual variables related to the referral process and treatment were collected. Data were collected by a single trained examiner and analyzed using SPSS software. The main reasons for referral to secondary care were dental caries and pulpal or periapical diseases associated with difficult-to-manage behavior. An absenteeism rate of 28.1% at the first pediatric dental visit and a resolution rate of 65.6% were found. Binary logistic regression analysis indicated that each day of waiting for specialized care resulted in a 0.3% of higher chance of absence for appointment. This also increased the chance by 0.7% in child who attended the first visit to complete treatment, suggesting that the waiting time for attendance was associated with absenteeism and resolubility. Public policies that expand providing child dental care in secondary care are recommended to improve access to and resolubility of services.

ABSTRACT

Introdução: A cárie na primeira infância ainda é um problema de saúde pública no Brasil, expresso pelas pequenas reduções no índice ceo-d na idade de 5 anos ao longo do tempo. Esse panorama pode refletir dificuldade de acesso e resolutividade nas Redes de Atenção à Saúde (RAS) no que se refere ao aten-dimento odontológico infantil. Objetivo: Este trabalho apre-senta uma revisão integrativa da literatura sobre o acesso e a resolutividade da atenção em saúde bucal na primeira infância nas RAS do Sistema Único de Saúde Brasileiro. Materiais e métodos: Foram consultadas as bases de dados do Medline/Pubmed, SciELO e Google Scholar e selecionados artigos publicados nos idiomas inglês e português entre 2005 e 2021. Revisão da literatura: Foi observado baixo percentual de uso de serviços odontológicos por crianças em idade pré-escolar, sendo o acesso influenciado por variáveis socioeconômicas e aspectos relacionados aos serviços. Discussão: Adoção da Estratégia Saúde da Família (ESF), realização de busca ativa, inclusão da saúde bucal nas ações programáticas de saúde infantil e adequada comunicação entre os pontos de atenção são fatores positivos ao acesso à saúde bucal. O atendimento odontológico infantil ocorre majoritariamente na atenção básica, havendo pouca expressividade na atenção especia-lizada, porém profissionais generalistas podem apresentar dificuldades em gerir o comportamento infantil durante o atendimento odontológico. Conclusão: Ações de educação permanente em Odontopediatria direcionadas aos profissionais da atenção primária são recomendadas, dada a capilaridade e o caráter familiar desse nível de atenção, porém a inclusão da especialidade de Odontopediatria nos Centros de Especialidades Odontológicas merece investimento e atenção dos gestores.


Introduction: Early childhood caries is still considered a public health problem in Brazil, detected by small reductions in the 5-year dmf-t index over time. This panorama may reflect difficulties in providing access and resolubility by Health Care Networks (HCN) with regards to children's dental care. Aim: This integra-tive review of the literature presents the access and resolubility of oral health care in early childhood in the HCN of the Brazilian Unified Health System. Mate-rials and methods: The Medline/Pubmed, SciELO, and Google Scholar databases were consulted, and articles published in English and Portuguese between 2005 and 2021 were selected. Literature review: A low use rate of dental services by preschool children was observed, and access is influenced by socioeconomic variables and aspects related to services. Discussion: Adoption of the Family Health Strategy (FHS), actively going in search, inclusion of oral health in programmatic actions of children health and proper communication between the points of care are positive factors in the access to oral health services. Children dental care occurs mostly in the primary level, with little expressiveness in specialized care. General practitioners may have difficulties in managing child behavior during dental treatment. Conclusion: Continuing education program in Pediatric Dentistry aiming primary care professionals is recommended, given the capillarity and the familiar pattern of the care level. The inclusion of the Pediatric Dentistry specialty in the Dental Specialties Centers deserves investment and attention from managers.

ABSTRACT

Objective: To assess the caries progression and the need for reintervention on occlusal ICDAS 4 lesions after different treatments. Material and Methods: The sample consisted of records of children treated in a public setting who had at least an occlusal ICDAS 4 lesion in primary and/or permanent molars. The radiographic images of ICDAS 4 lesions at the first and last appointments were classified as absence of radiolucency, radiolucent image at the enamel­dentin junction, at the outer half or inner of the dentin. The need for retreatment after different treatments (non-invasive - topical fluoride applications, oral hygiene instructions and dietary guidance, micro-invasive - resin-based sealant, or invasive - restoration) was assessed by reviewing clinical and radiographic records. The need for retreatment was defined as any complication requiring mending (e.g., caries progression, total loss of sealant, or restoration failure). The Poisson regression model was used to investigate the association between individual and tooth-related variables and the outcome. Results: Among the 111 lesions in 81 patients, most (73.0%) lesions were in primary molars. Most lesions (52.3%) did not exhibit radiolucency, whereas 29.7% had radiolucency at the outer half of the dentin. The mean follow-up was 18.8 ± 6.5 months. After follow-up, 82.9% of the lesions did not require retreatment. The prevalence of ICDAS 4 lesions that did not need retreatment was higher among lesions with radiolucency at dentin (p=0.01). Conclusion: Most occlusal ICDAS 4 lesions did not require reintervention, especially those exhibiting radiolucency in the outer half of the dentin (AU)


Objetivo: Avaliar a progressão de cárie e a necessidade de reintervenção em lesões oclusais ICDAS 4 após diferentes tratamentos. Material e Métodos: A amostra consistiu de prontuários de crianças atendidas em ambiente público que apresentavam pelo menos uma lesão oclusal ICDAS 4 em molares decíduos e/ou permanentes. As imagens radiográficas de lesões ICDAS 4 na primeira e última consultas foram classificadas como ausência de radiolucidez, imagem radiolúcida na junção esmalte-dentina, em metade externa ou interna da dentina. A necessidade de retratamento após diferentes tratamentos (não invasivo ­ aplicações tópicas de flúor, orientações de higiene e dieta, micro-invasivo ­ selante resinoso ou invasivo ­ restauração) foi avaliada por meio da revisão dos registros clínicos e radiográficos. A necessidade de retratamento foi definida como qualquer complicação que requer intervenção (por exemplo, progressão da lesão, perda total do selante ou falha na restauração). O modelo de regressão de Poisson foi utilizado para investigar a associação entre as variáveis individuais e dentárias e o desfecho. Resultados: Entre as 111 lesões em 81 pacientes, a maioria (73,0%) das lesões eram em molares decíduos. A maioria das lesões (52,3%) não exibiu radiolucidez, enquanto que 29,7% apresentaram radiolucidez em metade externa de dentina. O tempo de acompanhamento médio foi de 18,8 ± 6,5 meses. Após o acompanhamento, 82,9% das lesões não necessitaram de retratamento. A prevalência de lesões ICDAS 4 que não necessitaram de retratamento foi maior entre as lesões com radiolucidez em dentina (p=0,01). Conclusão: A maioria das lesões oclusais ICDAS 4 não requerem reintervenção, especialmente aquelas que exibem radiolucidez em metade externa da dentina.(AU)

ABSTRACT

Abstract Artificial intelligence (AI) is a general term used to describe the development of computer systems which can perform tasks that normally require human cognition. Machine learning (ML) is one subfield of AI, where computers learn rules from data, capturing its intrinsic statistical patterns and structures. Neural networks (NNs) have been increasingly employed for ML complex data. The application of multilayered NN is referred to as "deep learning", which has been recently investigated in dentistry. Convolutional neural networks (CNNs) are mainly used for processing large and complex imagery data, as they are able to extract image features like edges, corners, shapes, and macroscopic patterns using layers of filters. CNN algorithms allow to perform tasks like image classification, object detection and segmentation. The literature involving AI in dentistry has increased rapidly, so a methodological guidance for designing, conducting and reporting studies must be rigorously followed, including the improvement of datasets. The limited interaction between the dental field and the technical disciplines, however, remains a hurdle for applicable dental AI. Similarly, dental users must understand why and how AI applications work and decide to appraise their decisions critically. Generalizable and robust AI applications will eventually prove helpful for clinicians and patients alike.

ABSTRACT

Abstract: This study aimed to evaluate the efficacy of non-invasive and micro-invasive treatments on the arrest of occlusal enamel carious lesions in erupting permanent molars. This two-arm randomized clinical trial included 27 subjects, aged 5-11 years, with 64 erupting permanent molars presenting active occlusal enamel carious lesions (as assessed by the International Caries Detection and Assessment System [ICDAS]; scores 1-3). The sample was randomly assigned into two treatment groups: 1) resin-modified glass ionomer cement sealant (Clinpro XT Varnish; 3M ESPE) and 2) 4-week topical fluoride varnish application (Duraphat; Colgate). All children and parents received oral hygiene and dietary instructions. Teeth were evaluated at baseline and 3, 6, 9, and 12 months regarding the eruption stage, biofilm accumulation, as well as severity and activity of the carious lesions. The Kaplan-Meier method was used to evaluate the survival estimates for inactivation of the carious lesions for both treatment groups. Multivariate Cox regression models with shared frailty were performed to identify factors associated with the outcome (p < 0.05). After 12 months, 22% and 3% of the lesions treated with topical fluoride varnish and sealant, respectively remained active. The adjusted model demonstrated that younger children had a higher probability of active enamel carious lesions arresting (hazard ratio [HR] 0.42, 95% confidence interval [CI] 0.22-0.78; p=0.01). However, the probability of active enamel carious lesions arresting after sealant application was 8.85 times higher compared with fluoride varnish applications (p=0.01). Sealing is a more effective approach than fluoride varnish for arresting occlusal enamel carious lesions in erupting permanent molars.

ABSTRACT

ABSTRACT Objective: To compare the survival of occlusal and occlusal-proximal restorations performed with resin-modified glass-ionomer cement (RMGIC) in deciduous molars using rubber dam and cotton rolls isolation. Material and Methods: Ninety-two patients were included and 200 deciduous molars with cavitated occlusal or occlusoproximal dentin caries lesions were randomized into two groups: cotton rolls (n = 100) and rubber dam (n = 100) and RMGIC restorations were placed. At baseline and in the follow-up visit, presence, severity and activity of caries lesions were registered. Two independent, blinded examiners evaluated the treated teeth clinically using the USPHS criteria and radiographically after 9 months. Descriptive analysis, survival curve (log-rank test) and Cox regression were performed to assess risk factors related to failure. Results: Out of the 179 teeth (92 cotton rolls group and 87 rubber dam group) evaluated at 9-month follow-up period. No lesion progression was observed radiographically. The overall treatment success rate was 85.47% (83.47% for cotton rolls and 87.35 rubber dam group). No significant difference between isolation methods was observed in the log-rank test (p = 0.16). Cox regression showed no risk factors related to failure. Conclusion: No difference was found in the survival of occlusal and occlusal-proximal restorations performed with RMGIC in deciduous molars using a rubber dam and cotton rolls isolation after a 9-month follow-up period.

ABSTRACT

Abstract This study assessed the effectiveness of models for developing subsurface caries lesions in vitro and verified mineral changes by transverse microradiography (TMR). Enamel blocks from permanent (n=5) and deciduous teeth (n=5) were submitted to lesion induction by immersion in demineralizing solutions during 96 h, followed by pH cycles of demineralization (de) and remineralization (re) for 10 days. Two de-/re solutions were tested. Demineralizing solution "A" was composed by 2.2 mM CaCl2, 2.2 mM KH2PO4, 0.05 M acetic acid, with pH 4.4 adjusted by 1 M KOH. Demineralizing solution "B" was composed by 2.2 mM CaCl2, 2.2 mM NaH2PO4, 0.05 M acetic acid and 0.25 ppmF, with pH 4.5 adjusted by 1M KOH. Solution "A" produced cavitated lesions in permanent teeth, whereas solution "B" led to subsurface lesions in deciduous teeth. Solution "B" was then tested in enamel blocks from permanent teeth (n=5) and subsurface lesions were obtained, so that solution "B" was employed for both substrates, and the blocks were treated with slurries of a fluoride dentifrice (1450 ppm F, as NaF, n=5) or a fluoride-free dentifrice (n=5). Solution "B" produced subsurface lesions in permanent and primary teeth of an average (±SD) depth of 88.4µm (±14.3) and 89.3µm (±15.8), respectively. TMR analysis demonstrated that lesions treated with fluoride-free dentifrice had significantly greater mineral loss. This study concluded that solution "B" developed subsurface lesions after pH cycling, and that mineral changes were successfully assessed by TMR.


Resumo Este estudo avaliou a efetividade de modelos para o desenvolvimento de lesões de cárie subsuperficiais in vitro e verificou alterações minerais por microradiografia transversal (TMR). Blocos de esmalte de dentes permanentes (n = 5) e decíduos (n = 5) foram submetidos à indução de lesão por imersão em soluções desmineralizadoras durante 96h, seguido de ciclos de pH de desmineralização e remineralização por 10 dias. Duas soluções des-/re foram testadas. A solução desmineralizadora "A" foi composta por 2,2 mM de CaCl2, 2,2 mM de KH2PO4, 0,05 M de ácido acético, com pH de 4,4 ajustado por 1 M de KOH. A solução desmineralizadora "B" foi composta por 2,2 mM de CaCl2, 2,2 mM de NaH2PO4, 0,05 M de ácido acético e 0,25 ppmF, com pH de 4,5 ajustado por 1 M de KOH. A solução "A" produziu lesões cavitadas em dentes permanentes, enquanto a solução "B" apresentou lesões subsuperficiais em dentes decíduos. Portanto, a solução "B" foi posteriormente usada em blocos de esmalte de dentes permanentes (n = 5) e lesões subsuperficiais foram obtidas. Portanto, a solução "B" foi empregada para ambos os substratos, sendo metade deles tratada com dentifrício fluoretado e a outra metade com dentifrício livre de flúor. A solução "B" produziu lesões subsuperficiais de cárie com profundidade de 88.4µm (14.3) em dentes permanentes e com 89.3 µm (15.8) em dentes decíduos e TMR demonstrou que lesões tratadas com dentifrício sem flúor tiveram maior perda mineral. Este estudo concluiu que a solução "B" desenvolveu lesões subsuperficiais após o ciclo de pH e as alterações minerais foram avaliadas com sucesso por TMR.

ABSTRACT

Objetivo: Avaliar a efetividade de uma abordagem de tratamento não invasiva para a inativação de lesões não cavitadas de dentes decíduos e permanentes realizada na Clínica Infanto-Juvenil (CIJ) da Faculdade de Odontologia da Universidade Federal do Rio Grande do Sul (FO-UFRGS), identificando os fatores clínicos do paciente e associando-os ao sucesso clínico do tratamento. Métodos: Foram incluídos 55 prontuários de pacientes que receberam instruções de higiene bucal, controle de dieta e aplicações tópicas de flúor (ATF) na CIJ da FO-UFRGS entre 2016 e 2018. Foram coletados dados demográficos e clínicos referentes a avaliação da atividade de cárie dentária na consulta inicial e após o tratamento realizado: índice de placa visível (IPV), índice de sangramento gengival (ISG) e o número médio de dentes permanentes cariados, perdidos e restaurados (CPO-D) e/ou número médio de dentes decíduos cariados, extraídos ou com indicação de extração e restaurados (ceo-d). Na análise estatística foram utilizados os testes Qui-quadrado de Pearson, Exato de Fisher e Wilcoxon, nível de significância: p < 0,05. Resultados: Não houve diferença estatisticamente significativa quando se comparou as variáveis idade, sexo, IPV, ISG e ceo-d/CPO-D com o sucesso do tratamento. Houve diferença estatisticamente significativa comparando o IPV inicial com o final (p = 0,016) e número de lesões não cavitadas ativas inicial e final (p < 0,001), mas não houve diferença para o ISG inicial e final (p = 0,324). Conclusão: Baseado nos achados da redução do IPV e da redução no número de lesões não cavitadas ativas ao final do tratamento, sugere-se que a abordagem de tratamento não invasiva para inativação de lesões de cárie dentária não cavitadas aplicada na CIJ da FO-UFRGS é efetiva.


Aim: To evaluate the effectiveness of a non-invasive treatment on the arrest of non-cavitated caries lesions of primary and permanent teeth performed at the Pediatric Clinic (PC) at the Dental Teaching Hospital of the Federal University of Rio Grande do Sul (DT-UFRGS), identifying the patient's clinical factors and associating them with the clinical success of the treatment. Methods: This study included 55 patient's medical records who received oral hygiene instructions, diet control, and topical fluoride applications (TFA) at the PC of DT-UFRGS between 2016 and 2018. Demographic and clinical data regarding the evaluation of caries activity in the initial visit and after the performed treatment were collected: visible plaque index (VPI), gingival bleeding index (GBI), and DMF-T caries index (average number of decayed, missing, and restored permanent teeth), and/or dmf-t (average number of decayed, extracted or with recommendation for extraction, and restored deciduous teeth). Pearson's Chi-square, Fisher's Exact, and Wilcoxon tests were used for statistical analysis, significance level: p < 0.05. Results: No significant difference was observed when the variables of age, gender, VPI, CBI, DMF-T/dmf-t were compared with treatment success. A statistically significant difference was found when comparing the initial with the final VPI (p = 0.016), as well as the number of initial and final active non-cavitated carious lesions (p < 0.001), but no difference was identified for the initial and final GBI (p = 0.324). Conclusion: Based on the findings of VPI reduction and reduction in the number of active non-cavitated carious lesions upon completion of treatment, it is suggested that the non-invasive treatment for arrestment of non-cavitated carious lesions applied at the PC of DT-UFRGS is effective.

ABSTRACT

Objetivo: Avaliar a efetividade de uma abordagem de tratamento não invasiva para a inativação de lesões não cavitadas de dentes decíduos e permanentes realizada na Clínica Infanto-Juvenil (CIJ) da Faculdade de Odontologia da Universidade Federal do Rio Grande do Sul (FO-UFRGS), identificando os fatores clínicos do paciente e associando-os ao sucesso clínico do tratamento. Métodos: Foram incluídos 55 prontuários de pacientes que receberam instruções de higiene bucal, controle de dieta e aplicações tópicas de flúor (ATF) na CIJ da FO-UFRGS entre 2016 e 2018. Foram coletados dados demográficos e clínicos referentes a avaliação da atividade de cárie dentária na consulta inicial e após o tratamento realizado: índice de placa visível (IPV), índice de sangramento gengival (ISG) e o número médio de dentes permanentes cariados, perdidos e restaurados (CPO-D) e/ou número médio de dentes decíduos cariados, extraídos ou com indicação de extração e restaurados (ceo-d). Na análise estatística foram utilizados os testes Qui-quadrado de Pearson, Exato de Fisher e Wilcoxon, nível de significância: p < 0,05. Resultados: Não houve diferença estatisticamente significativa quando se comparou as variáveis idade, sexo, IPV, ISG e ceo-d/CPO-D com o sucesso do tratamento. Houve diferença estatisticamente significativa comparando o IPV inicial com o final (p = 0,016) e número de lesões não cavitadas ativas inicial e final (p < 0,001), mas não houve diferença para o ISG inicial e final (p = 0,324). Conclusão:Baseado nos achados da redução do IPV e da redução no número de lesões não cavitadas ativas ao final do tratamento, sugere-se que a abordagem de tratamento não invasiva para inativação de lesões de cárie dentária não cavitadas aplicada na CIJ da FO-UFRGS é efetiva.


Aim: To evaluate the effectiveness of a non-invasive treatment on the arrest of non-cavitated caries lesions of primary and permanent teeth performed at the Pediatric Clinic (PC) at the Dental Teaching Hospital of the Federal University of Rio Grande do Sul (DT-UFRGS), identifying the patient's clinical factors and associating them with the clinical success of the treatment. Methods: This study included 55 patient's medical records who received oral hygiene instructions, diet control, and topical fluoride applications (TFA) at the PC of DT-UFRGS between 2016 and 2018. Demographic and clinical data regarding the evaluation of caries activity in the initial visit and after the performed treatment were collected: visible plaque index (VPI), gingival bleeding index (GBI), and DMF-T caries index (average number of decayed, missing, and restored permanent teeth), and/or dmf-t (average number of decayed, extracted or with recommendation for extraction, and restored deciduous teeth). Pearson's Chi-square, Fisher's Exact, and Wilcoxon tests were used for statistical analysis, significance level: p < 0.05. Results: No significant difference was observed when the variables of age, gender, VPI, CBI, DMF-T/dmf-t were compared with treatment success. A statistically significant difference was found when comparing the initial with the final VPI (p = 0.016), as well as the number of initial and final active non-cavitated carious lesions (p < 0.001), but no difference was identified for the initial and final GBI (p = 0.324). Conclusion: Based on the findings of VPI reduction and reduction in the number of active non-cavitated carious lesions upon completion of treatment, it is suggested that the non-invasive treatment for arrestment of non-cavitated carious lesions applied at the PC of DT-UFRGS is effective.

ABSTRACT

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.

ABSTRACT

ABSTRACT This study sought to provide an overview of current cariology education for undergraduate Brazilian dental students. Data collection was via a Portuguese version of a 12-item questionnaire (Schulte et al., 2011) that was sent to all Brazilian dental schools (n = 219). The response rate was 57.0% (n = 125). Of the schools that returned the questionnaire, 84.8% supported the development of a Brazilian cariology curriculum. The units responsible for teaching cariology were predominantly operative dentistry (49.6%), pediatric dentistry (49.6%), dental public health (44.8%), and cariology (32%). Theoretical teaching of cariology (74.4%) and pre-clinical exercises (63.2%) were cited to occur mainly during the second year of the course, while clinical activities were placed in the third (71.2%) and fourth (64.8%) years. Among respondents, 76.8% of the schools included dental erosion and 86.4% included defects of dental hard tissues, such as abrasion, in teaching cariology. This survey was able to determine the panorama of cariology education in Brazil and to detect some differences among Brazilian geographic areas. The promotion of a workshop to discuss the topics that should be taught to undergraduate dental students and the development of a Brazilian core curriculum in cariology would be likely to reduce the differences in teaching cariology in Brazil.


RESUMO Este estudo teve como objetivo apresentar um panorama do ensino de cariologia nos cursos de graduação em Odontologia no Brasil. A coleta de dados foi realizada por meio de uma versão em Português Brasileiro de um questionário de 12 itens (Schulte et al., 2011) que foi enviado a todas as faculdades de Odontologia brasileiras (n = 219). A taxa de resposta foi de 57,0% (n = 125). Dentre as faculdades que responderam o questionário, 84,8% apoiam o desenvolvimento de um currículo brasileiro de cariologia. As disciplinas responsáveis por lecionar os conteúdos de cariologia são principalmente dentística (49,6%), odontopediatria (49,6%), saúde bucal coletiva (44,8%), e cariologia (32%). O ensino teórico de cariologia (74,4%) e os exercícios de pré-clínica (63,2%) são abordados principalmente durante o segundo ano do curso, enquanto as atividades clínicas ocorrem, em geral, no terceiro (71,2%) e quarto (64,8%) anos. Dentre os respondentes, 76,8% das faculdades incluem erosão dentária e 86,4% incluem defeitos dos tecidos dentários duros, como abrasão, no ensino da cariologia. Essa pesquisa foi capaz de determinar o panorama do ensino da cariologia no Brasil e detectar algumas diferenças de currículo entre as regiões do país. A promoção de um workshop para discutir os assuntos que devem ser ministrados aos estudantes de graduação em Odontologia e para desenvolver um currículo brasileiro de cariologia seria válida para reduzir as diferenças no ensino de cariologia no Brasil.

ABSTRACT

Introduction: Erosive tooth wear (ETW) is defined as a mechanical chemical process that results in a cumulative loss of hard tissue without the involvement of bacteria. This process may occur in permanent and deciduous teeth and may also reach the dentin tissue. Patients who report chronic diseases, such as respiratory allergy and bronchial asthma, or recurrent acute diseases, such as tonsillitis, allergic rhinitis, sinusitis, and otitis, commonly use drugs for prolonged periods; thus, more attention should be given to the dental aspects since the drugs may cause undesirable effects. Objective: This paper aims to report and discuss a clinical case of a nine-year-old, male, Caucasian, asthmatic patient who continually uses anti-asthmatic medications and has developed ETW. Case report: According to the patient's needs, oral hygiene instructions (use of fluoride stannous dentifrice, dental floss, and topical fluoride applications), daily use of mouthwash solution containing 0.05% sodium fluoride, and dietary guidance were recommended. Conclusion: An early and accurate diagnosis of ETW lesions and recognition of specific etiological factors allow the professional to elaborate an individualized prevention and control program for ETW progression.


Introdução: O desgaste dentário erosivo é definido como um processo químico mecânico que resulta em uma perda cumulativa de tecido duro, sem o envolvimento de bactérias. Esse processo pode ocorrer em dentes permanentes e decíduos, podendo atingir o tecido dentinário. Pacientes que relatam doenças crônicas, como alergia respiratória e asma brônquica ou doenças agudas recorrentes como amigdalite, rinite alérgica, sinusite e otite, comumente usam medicamentos por períodos prolongados, portanto, mais atenção deve ser dada ao aspecto odontológico, uma vez que os medicamentos podem causar efeitos indesejáveis. Objetivo : Este trabalho tem como objetivo relatar e discutir um caso clínico de um paciente de nove anos, asmático, caucasiano, sexo masculino, que faz uso contínuo de medicamentos anti-asmáticos e desenvolveu o desgate erosivo dentário. Relato do caso: De acordo com as necessidades do paciente foi realizado instruções de higiene oral (uso de dentifrício contendo fluoreto estanhoso, fio dental e aplicações tópicas de flúor). Uso diário de enxaguatório bucal contendo 0,05% de fluoreto de sódio também foi recomendado e orientações dietéticas foram realizadas. Conclusão: O diagnóstico precoce e preciso das lesões de desgaste erosivo e o reconhecimento dos fatores etiológicos específicos permite o profissional elaborar um programa individualizado de prevenção e controle da progressão do desgaste erosivo dentário.

ABSTRACT

ABSTRACT Albright hereditary osteodystrophy is a disorder comprising phenotypic characteristics of genetic origin, such as short stature, obesity, and brachydactyly. It is a rare disorder and is related to pseudohypoparathyroidism. Within dentistry, it may be associated with enamel hypoplasia and late eruption. Furthermore, due to neurological problems, these patients may impose behavioural difficulties during dental appointments. The present study aims to describe the case of a patient with a possible diagnosis of Albright hereditary osteodystrophy, presenting symptoms and limitations to dental management.


RESUMO A Osteodistrofia Hereditária de Albrighth é uma alteração que compreende características fenotípicas de origem genética, tais como baixa estatura, obesidade e braquidactília. É uma desordem rara e está relacionada com o pseudo-hipoparatireoidismo. No âmbito da Odontologia pode estar associada à hipoplasia de esmalte e erupção tardia dos dentes. Além disto em função de problemas neurológicos estes pacientes podem impor dificuldades de comportamento no momento do atendimento. O presente estudo objetivou descrever um caso clínico de uma paciente, com o possível diagnóstico de Osteodistrofia Hereditária de Albright, apresentando sintomas e limitações ao tratamento odontológico.

ABSTRACT

ABSTRACT Objective: To evaluate the effect of erosive challenges on the tooth- restoration interface of deciduous teeth treated with different adhesive protocols. Material and Methods: 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. Results: 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). Conclusions: 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).

ABSTRACT

RESUMO Introdução As doenças e desordens bucais, bem como hábitos orais, podem causar impacto na qualidade de vida das crianças. Objetivo Associar a cárie dentária, maloclusão e hábitos orais com a qualidade de vida de crianças pré-escolares. Métodos Estudo transversal com 93 crianças de 3 a 5 anos de idade, acometidas, ou não, por lesões de cárie não tratadas. Os responsáveis responderam ao questionário sobre hábitos orais e ao Questionário sobre a Qualidade de Vida Relacionada à Saúde Bucal de Crianças na Idade Pré-escolar (B-ECOHIS). Um odontopediatra avaliou a gravidade das lesões de cárie e a presença de alterações oclusais. O nível de significância utilizado foi de 5%. Resultados O B-ECOHIS evidenciou impacto na qualidade de vida, conforme o aumento da idade, nos domínios dos sintomas, aspectos psicológicos, autoimagem e interação social e de função familiar. A cárie dentária apresentou impacto sobre a qualidade de vida das crianças e de seus familiares, especialmente em relação aos domínios dos sintomas e limitações. Hábitos de respiração oronasal e chupeta também evidenciaram efeitos negativos na qualidade de vida das crianças e de seus familiares. Não foi observada associação entre maloclusão e qualidade de vida relacionada à saúde oral. Conclusão A cárie dentária, os hábitos de sução de chupeta e de respiração oronasal demonstraram impacto negativo na qualidade de vida relacionada à saúde oral das crianças.


ABSTRACT Introduction Oral diseases and disorders as well as oral habits can impact the quality of life of children. Purpose To associate the dental caries, malocclusion and oral habits with the quality of life of preschool children. Methods Cross-sectional study with 93 children from three to five years of age who have or have not been affected by untreated carious lesions. Parents answered the questionnaire on oral habits and quality of life instrument related to oral health denominated Early Childhood Oral Health Impact Scale (B-ECOHIS). A pediatric dentist assessed the severity of the carious lesions and the presence of occlusal disorders. The level of significance used was 5%. Results The B-ECOHIS demonstrated impact on quality of life with increasing age in the fields of symptoms, psychological aspects, self-image and social interaction and family function. Dental caries were shown to have an impact on the quality of life of children and their families, especially in relation the domains of symptoms and limitations. Oronasal breathing and pacifier habits negatively impacted the quality of life of children and their families. There was no association between malocclusion and quality of life related to oral health. Conclusion The dental caries, the pacifier suction habits and oronasal breathing demonstrated negative impact on quality of life related to oral health of children.
