RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVES: This two-arm, parallel-group, tooth-randomised, controlled noninferiority clinical trial aimed to compare survival rates between the sealing and restoring of cavitated occlusal carious lesions in dentine [International Caries Detection and Assessment System (ICDAS) 5] of deciduous molars using resin-modified glass-ionomer cement (RMGIC) and to assess caries progression radiographically. MATERIALS AND METHODS: A total of 68 molars with ICDAS 5 occlusal lesions were randomly allocated into two groups, a sealing group (n = 31), in which RMGIC was placed directly over the carious lesion, and a restoration group (n = 37), in which a restoration with the same material was placed after selective caries removal. During the baseline and follow-up visits, dental caries was registered and caries activity was assessed according to a visuotactile criterion. At baseline, patient caries status (dmf-t) and cavity depth and extent (mesiodistal and buccolingual) were measured before RMGIC placement. An independent and blinded examiner evaluated the treated teeth using the USPHS criteria after one and two years. Standardised interproximal radiographs were taken for caries progression assessments. RESULTS: During the follow-up period, no lesion progression was observed radiographically. After one year (n = 60; 27 sealed and 33 restored) and two years (n = 48; 23 sealed and 25 restored) of follow-up, the treatment success rates were 78.8% and 76.0% in the restoration group and 59.3% and 47.8% in the sealing group, respectively. Multivariate Cox regression showed that lesions smaller than 2 mm in the mesiodistal extent were less prone to fail after one year (p = 0.03). However, survival curves (log-rank test) were statistically significantly different only after two years (p < 0.001). CONCLUSIONS: Sealing ICDAS 5 occlusal lesions of deciduous molars using RMGIC achieved lower survival rates than restorations. Both sealing and restoration effectively arrested caries progression for two years. Clinical relevance Sealing dentine carious lesions can be effective for treating lesions involving the inner and outer half of the dentine. Ultraconservative treatments can arrest carious lesions presenting obvious cavitation in primary molars. TRIAL REGISTRATION: ReBEC Register no. RBR-225n35.

RESUMO

A randomized controlled parallel clinical trial was conducted to evaluate the efficacy of the association of 1.23% topical professional acidulated phosphate fluoride (APF) gel with oral hygiene and dietary instructions on the arrest of active non-cavitated lesions in permanent, mixed, and temporary dentition in children between 3 and 12 years of age. Ninety-eight caries-active children were randomly divided into two groups: a fluoride gel group (n = 49) and a non-fluoridated gel group (n = 49). Each group received up to eight weekly applications of gel, weekly professional toothbrushing with oral hygiene instructions and dietary counselling. Caries lesions were assessed qualitatively through visual-tactile criteria performed in three stages: initial, intermediate, and final. Regression models were applied to identify risk indicators for caries control. Between-group comparison regarding the time taken to arrest the lesions was performed using Chi-squared and Fisher's exact tests. Seventeen children did not receive the allocated intervention, and one was lost to follow-up (n = 80). There was no difference between the control and placebo groups regarding the time to the arrest of the lesion (p >.05). The treatments showed similar results without significant statistical difference (p = 0.33; 95%CI: 0.32-1.48). No adverse effects were observed. It can be concluded that no additional effect of the association of 1.23% APF gel with oral hygiene using fluoride dentifrice and dietary instructions on the arrest of active non-cavitated lesions could be established. We can also confirm the importance of toothbrushing frequency and, consequently, the visible plaque reduction in the control of caries activity. RBR-37V5S3.

RESUMO

Qualitative approach about the implications that occur succeeding the premature loss teeth is still insufficient. This study aimed to understand the experience of early loss of deciduous teeth in children's lives, from the perspective of their caregivers. Qualitative case study included 52 caregivers of children from an outpatient service of a public university in the south of Brazil. Early loss of deciduous teeth to trauma or caries was identified through analysis of health records, and afterwards, semi-structured interviews were performed. Textual material was interpreted through the content analysis proposed by Bardin, supported by the ATLAS.ti software. The theoretical perspective of stigma was guided according to the principles of the phenomenology of Maurice Merleau-Ponty, centred on the experience of early loss of deciduous teeth as a historic-cultural expression of a social group. According to caregivers, premature loss of deciduous teeth due to trauma or decay brings functional limitations with chewing and speaking, and impairments related to social interaction with other children. The repercussions of missing teeth were not limited to the child's image, but also brought changes in families' daily lives. However, when early tooth loss was due to extraction because of pain and suffering, caregivers perceived the loss as 'commonplace' in children's lives. The understanding of how children see themselves without teeth in their social world for their caregivers, which also includes their family and friends, determines how much experiencing tooth loss affects their lives. Besides, caregivers' perceptions related to early loss of deciduous teeth should be included in strategies of oral health promotion programs.

RESUMO

The aim of this study was to compare the acquired enamel pellicle protein profile of professional wine tasters with mild and moderate erosive tooth wear. Twelve professional wine tasters participated (3 from a low tooth wear group; 9 from a high tooth wear group). Acquired enamel pellicle samples were collected and processed for proteomic analysis (nLC-ESI-MS/MS). The acquired enamel pellicle proteomic profile was different between the groups. The proteins found exclusively in the low tooth wear group were histatins 1 and 3 and mucins 7 and 21. When comparing the wear groups, proteins with higher levels in the low tooth wear group included neutrophil defensins (1 and 3), lysozyme C, lysozyme, myeloperoxidase, and squalene monooxygenase. In conclusion, the findings indicate that the proteins found at higher levels in the low tooth wear group and proteins exclusively found in the low tooth wear group might be protective and, therefore, could be good candidates for further studies regarding their potential to be added to dental products to protect professional wine tasters from extrinsic erosive tooth wear.

RESUMO

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.

RESUMO

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

Purpose: The purpose of this split-mouth, randomized, controlled clinical trial was to assess the progression of early proximal carious lesions on primary molars after resin infiltration. Methods: Twenty-eight children presenting two primary molars with proximal carious lesions detected radiographically (on the outer half of the enamel up to the outer one-third of dentin) were included. Baseline assessments consisted of standard digital bitewing radiographs, Visual Plaque Index (VPI), Gingival Bleeding Index (GBI), and visual examination of caries. Proximal lesions were randomly allocated into two groups: (1) resin infiltration (test) and (2) no infiltration (control). Reassessments were performed after two years. Lesion progression was considered when the radiographic score increased. Results: A significant difference in lesion progression was observed between test (54.1 percent) and control (79.2 percent) groups after two years (McNemar's test, P=0.03). Logistic regression for matched pairs showed that the test group had an 82 percent lower risk of caries progression (odds ratio equals 0.18, 95%CI 0.29 to 0.31). Conclusions: Infiltrating proximal lesions decreases radiographic caries progression in primary molars after a two-year follow-up period.

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.

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

Sleep bruxism (SB) is a masticatory muscle activity during sleep that can cause several consequences to the stomatognathic system. This systematic review investigated the impact of SB on oral health-related quality of life (OHRQoL) of 0- to 6-year-old children. Literature search was undertaken through PubMed/MEDLINE, LILACS, Scopus, TRIP, Livivo databases, and grey literature. The search was conducted with no publication year or language limits. Two reviewers independently selected the studies, extracted the data and assessed the risk of bias. The quality of evidence was assessed using GRADE. From 185 potentially eligible studies, three were included in the review. All studies were conducted in Brazil, published between 2015 and 2017, and used the B-ECOHIS instrument to evaluate OHRQoL. Two studies found no association between SB and OHRQoL, whereas one showed a significant negative impact of SB on the OHRQoL of children. SB was associated with respiratory problems, presence of tooth wear, dental caries, malocclusion as well as income and pacifier use. Risk of bias ranged from moderate to high, and the quality of evidence was judged as very low. The evidence is currently insufficient for definitive conclusions about the impact of SB on OHRQoL of children.

RESUMO

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.

RESUMO

OBJECTIVE: Children are an important portion of the population of the territories covered by Primary Health Care (PHC), with needs and characteristics that can be managed at this level of care. Therefore, it is essential that professionals working in PHC be capable of providing child care. The aim of this study was to evaluate the performance of dentists working in primary healthcare (PHC) in a pediatric dentistry distance learning (DL) course, and to investigate the relationship between the grades earned on questionnaires applied after each course module and features of their personal and professional profile. METHOD: The study used a convenience sample of 201 dentists working in PHC, who enrolled in a DL course offered by a telehealth center in the state of Rio Grande do Sul, Brazil. The course consisted of video classes on restorative dentistry, endodontics, dental trauma, and clinical management in pediatric dentistry. After completing each module, each participant was asked to answer a questionnaire to assess their acquisition of immediate knowledge. Student's t-test and the ANOVA test were used to assess the relationship between the mean grade earned and the variables of sex, age, type of training institution, time since graduation, and years working in PHC. RESULTS: A significant relationship was observed between type of training institution (public) and the grade earned on the restorative dentistry questionnaire, and also between time since graduation and the grade earned on the dental trauma questionnaire (p < 0.05). No relationship was observed between the personal/professional variables and the grades earned on the endodontics and clinical management questionnaires. Grades were significantly lower on the endodontics questionnaire (p < 0.05). DISCUSSION: The large number of dentists enrolled in this DL course is a demonstration that there is great interest in pediatric dentistry contents. Improvement of DL courses may lead to the enhancement of professionals and their skills, and to a significant improvement in the quality of care provided to children in public health networks. CONCLUSION: It was concluded that training in a public institution and a longer time since graduation positively influenced the grades earned on the restorative dentistry and dental trauma questionnaires, respectively.

RESUMO

Background: The aim of the present study was to assess the level of satisfaction of dentists working in primary healthcare (PHC) with a Distance learning (DL) course in pediatric dentistry offered by the TeleHealthRS center, and to the investigate possible associations between the variables indicative of their satisfaction and their performance on the questionnaires applied before and after the course. Methods: The course was offered in 2015 by the Federal University of Rio Grande do Sul (UFRGS) together with the TeleHealthRS center in Brazil. Data were collected on the participants' personal and professional profile, their pre- and post-course knowledge about pediatric dentistry, and their satisfaction with the course. Student's t-test and the ANOVA test were used to assess the possible associations between the variables indicative of their satisfaction and their performance on the questionnaires applied before and after the course. Results: Overall, the participants were satisfied with the course, however, no statistically significant association was found between the variables indicative of their satisfaction and the grades they earned on the pre- and post-course questionnaires. Conclusion: The available pediatric dentistry course received positive evaluations from the participants, constituting a possible strategy for the qualification of primary care dentists. Future studies are warranted to further investigate the expectations of DL course participants, aiming to enhance the quality of future editions of this learning modality for pediatric dentistry contents.

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.
