RESUMEN

OBJECTIVES: To compare the prevalence of parafunctional habits, erosive tooth wear and occurrence of tooth injuries among children being under the care of Social Welfare Centre and children treated in the Department of Children's Dentistry of the Medical University of Warsaw. STUDY DESIGN: The study contains environmental and medical interviews, record-based analysis and clinical examination. Parafunctional habits were rated on the base of dental interviews and clinical examinations. The occlusal surfaces were evaluated by visual examination using modified tooth wear index (TWI). Tooth injuries were reported from a medical interview labeled using Andreasen classification. The consent of the bioethics committee and guardians of children participated in the study was obtained. RESULTS: The study involved 782 patients, including 404 children from dysfunctional families (average age 11,4 ± 3,7) and 378 from ordinary families-control group (8,53 ± 3,92). In the study group we observed higher prevalence of erosive tooth wear (44,66% vs 18,02% p=0,000), dental trauma (9,4% vs 3,44% p=0,001) and a presence of parafunctional habits (67,8% vs 20,4 % p=0,000). CONCLUSION: The occurrence of parafunctional habits, erosive tooth wear and tooth injuries may be an indicator of domestic violence and a component of maltreated child syndrome.

RESUMEN

OBJECTIVES: This study was conducted to examine the tooth wear status of nasopharyngeal-carcinoma (NPC) patients who had received radiotherapy at least 5-year previously, and to investigate the salivary parameters that may be associated with the tooth wear. METHODS: Tooth wear status of NPC survivors were clinically assessed using the Exact Tooth Wear Index. A tooth was graded to have severe wear when more than one-third of its buccal/occlusal/lingual surface had dentine loss. At the subject-level, percentages of anterior/posterior/all teeth with severe wear were calculated. Age, number of teeth, flow-rate/buffering capacity/pH of stimulated whole (SWS) and parotid (SPS) saliva's were collected. Correlation and multiple-linear regression tests were performed at the significance level α = 0.05. RESULT: Sixty-eight participants (mean age of 60.0 ±â€¯8.9), 697 anterior and 686 posterior teeth were examined with a mean of 10-years post-radiotherapy. Severe tooth wear was found in 63 (92.6 percent) participants, 288 anterior and 83 posterior teeth. The mean percentage of anterior/posterior/all teeth with severe wear were 42.3 ±â€¯28.1, 14.5 ±â€¯19.9 and 30.0 ±â€¯21.7. Anterior teeth, particularly the incisal surface of central incisors were most affected. The mean flow-rate of SWS and SPS were 0.1 ±â€¯0.1 ml/min and 0.03 ±â€¯0.07 ml/min respectively. Thirty (44.1 percent) and 48 (70.6 percent) participants were found to have low/no buffering capacity of SWS and SPS respectively. Multiple-regression analyses revealed the SWS flow-rate was associated with the percentage of anterior teeth with severe wear (p=0.03). CONCLUSION: Anterior tooth wear is a significant dental problem among NPC survivors and was associated with hypo-salivation. CLINICAL SIGNIFICANCE: Patients with hypo-salivation should be being monitored for tooth wear particularly on the anterior teeth.

RESUMEN

The objective of the study was to analyze the surface area (SA) of the wear caused by simulated chewing on human enamel and opposing restorative material, namely: composite resin (CR), porcelain fused to metal (PFM), lithium disilicate (LD), or monolithic zirconia (MZr). Forty-eight premolars were selected as enamel specimens and divided randomly into 4 groups (n = 48; n =12) used as antagonists in chewing simulation (250,000 loading cycles) against one of the four selected test materials. Enamel and material specimens were scanned and evaluated under digital microscope, and wear SA (mm2) were recorded. Descriptive statistics, paired t-test, one-way ANOVA, and post-hoc Tukey-HSD tests were used for statistics (p < 0.05). The smallest and largest SA were exhibited by enamel against LD (0.80 mm2) and PFM (1.74 mm2), respectively. PFM (3.48 mm2) showed the largest SA and CR (2.28 mm2) showed the smallest SA. Paired t-test for SA values showed significant difference (p < 0.05) in all wear comparisons between materials and enamel antagonists. The wear of materials were greater than that of their respective enamel antagonists (p < 0.05). One-way ANOVA of the logarithmic means of wear SA revealed significant differences (P<0.05). Post-hoc Tukey test revealed significance for PFM (p < 0.05) with other materials. Wear of all test materials was greater compared to the wear of enamel antagonists. PFM and LD caused the largest and the smallest enamel wear, respectively. CR, LD, and MZr are more resistant than PFM to wear after simulated chewing against enamel.

RESUMEN

Purpose: In a cross-sectional population-based study of 888 5-year-old preschoolers from Teresina, Brazil, to determine the prevalence and factors associated with erosive tooth wear (ETW).
Materials and Methods: In a questionnaire, parents provided information on sociodemographic factors, their children's eating/drinking habits, and oral health. Dental examination was performed at the schools by two calibrated examiners for the diagnosis of ETW, following the criteria of the modified O'Brien Index.
Results: The prevalence of ETW was 3.3%. The maxillary incisors were the most highly affected teeth, followed by the mandibular and maxillary molars. The majority of the lesions reached only the enamel (72.1%) and up to 1/3 of the dental surface (63.1%). The occlusal surface was the most affected (47.8%). Preschoolers who had an acidic food-consumption profile had a 2.74 times (95% CI = 1.03-7.30) higher chance of having ETW than children without this profile.
Conclusion: The prevalence of erosive tooth wear on the deciduous teeth was low and associated with the consumption of acidic beverages.

RESUMEN

INTRODUCTION: Several oral problems may be perceived in individuals who were submitted to bariatric surgery, due to metabolic and behavioral changes relative to diet and oral hygiene. Tooth wear appears to suffer impact after bariatric surgery, because there may be an increase in gastroesophageal reflux. OBJECTIVE: To systematically review the literature regarding the impact of bariatric surgery on gastroesophageal reflux and tooth wear. METHOD: The following databases were accessed by two independent, calibrated examiners: PubMed, Medline, Lilacs, Scielo and Cochrane using the following descriptors: "bariatric surgery" AND "dental erosion" OR "bariatric surgery" AND "dental erosion" AND "gastroesophageal reflux disease". After excluding duplicate studies, 12 studies were initially evaluated by the title and abstract. The excluded studies were those without relevance to the present research, literature review studies and case reports. Thus, four articles were included in this study. All the articles evaluated indicated high association between gastroesophageal reflux and tooth wear in patients submitted to bariatric surgery. Association of these outcomes was more evident six months after the surgical procedure. CONCLUSION: Patients submitted to bariatric surgery showed higher prevalence of gastroesophageal reflux and tooth wear.

RESUMEN

The underlying mechanism of the development of cups and grooves on occlusal tooth surfaces is still unclear. The aim of this study was to evaluate factors contributing to in-vitro cup formation, and to elucidate the clinical process. Extracted human molar teeth were exposed to acidic aqueous solutions at pH of 4.8 and 5.5 in combination with different loading conditions: no load (0N, control), 30N or 50N. Before and after 3 months exposure, the samples were scanned using a non-contact profilometer. A statistically significant difference between a loading of 0N and 50N was found at pH 4.8 (p < 0.002). Cup shaped lesions had formed only at pH of 4.8, in the 30N and 50N groups. The study showed that a cup can arise fully in enamel and that this requires simultaneous acidic and mechanical loading.

RESUMEN

Early modern humans (EMH) are often touted as behaviorally advanced to Neandertals, with more sophisticated technologies, expanded resource exploitation, and more complex clothing production. However, recent analyses have indicated that Neandertals were more nuanced in their behavioral adaptations, with the production of the Châtelperronian technocomplex, the processing and cooking of plant foods, and differences in behavioral adaptations according to habitat. This study adds to this debate by addressing the behavioral strategies of EMH (n = 30) within the context of non-dietary anterior tooth-use behaviors to glean possible differences between them and their Neandertal (n = 45) counterparts. High-resolution casts of permanent anterior teeth were used to collect microwear textures of fossil and comparative bioarchaeological samples using a Sensofar white-light confocal profiler with a 100x objective lens. Labial surfaces were scanned, totaling a work envelope of 204 x 276 µm for each individual. The microwear textures were examined for post-mortem damage and uploaded to SSFA software packages for surface characterization. Statistical analyses were performed to examine differences in central tendencies and distributions of anisotropy and textural fill volume variables among the EMH sample itself by habitat, location, and time interval, and between the EMH and Neandertal samples by habitat and location. Descriptive statistics for the EMH sample were compared to seven bioarchaeological samples (n = 156) that utilized different tooth-use behaviors to better elucidate specific activities that may have been performed by EMH. Results show no significant differences between the means within the EMH sample by habitat, location, or time interval. Furthermore, there are no significant differences found here between EMH and Neandertals. Comparisons to the bioarchaeological samples suggest both fossil groups participated in clamping and grasping activities. These results indicate that EMH and Neandertals were similar in their non-dietary anterior tooth-use behaviors and provide additional evidence for overlapping behavioral strategies employed by these two hominins.

RESUMEN

RATIONALE: Full-mouth rehabilitation of patients with bruxism and severely worn dentition poses a great challenge to clinicians. Several treatment planning methods and restorative materials are used to treat tooth wear in modern dentistry. Clinicians should be able to select the most suitable treatment planning methods and materials for individual patients depending on their specific situation. PATIENT CONCERNS: A 47-year-old male was referred for evaluation of a severely worn dentition. DIAGNOSES: Clinical and radiographic evaluation revealed tooth wear in the entire dentition. The interocclusal distance at rest was 4 mm, and the patient had a parafunctional habit of bruxism. INTERVENTIONS: A digital smile design was used to formulate a treatment plan. Full-mouth rehabilitation was performed using a combination of conventional and digital materials and methods. OUTCOMES: The full-mouth restoration showed satisfactory functions and esthetics. No complications were observed in the restorations, supporting tissues, and temporomandibular joints during 2-year follow-up. LESSONS: In clinical practice, it is important to determine the optimal combination of the available methods for treatment planning. This case report details the formulation of a unique treatment plan for the dental rehabilitation of a severely worn out dentition, which is considered challenging due to the limitations imposed by biological tissues and restorative materials. The use of conventional and digital tools for treatment planning, patient education, and treatment execution was demonstrated.

RESUMEN

OBJECTIVES: Central African small-scale foragers subsist primarily on hunting game activities and wild plant-food gathering. Starch-rich tubers are underground storage organs (USOs) and staple food resources in savanna and tropical rainforests. However, little is known about the effect of USO consumption on tooth wear development in living hunter-gatherers. We report age- and sex-dependent tooth wear rates in forest-dwelling Baka Pygmies with well-documented wild-yam-tuber-based diet to explore the long-term impact of USO mechanical hardness and abrasiveness on the wearing down of the teeth. MATERIALS AND METHODS: Percentages of dentine exposure (PDEs) of permanent left mandibular first molars (M1 ) were recorded using in vivo high-resolution replicas of Baka individuals (aged 8-33 years), inhabiting Le Bosquet district in Cameroon (Western Africa). Regression and covariance analyses were used to test the effect of individual aging by sex on PDE rates. RESULTS: We found a strong increase of PDE by age among Baka individuals. No evidence of sexual dimorphism in wear patterns suggests similar sex-related dietary and masticatory demands during growth. Overall, greatest dentine exposure values ≈4% denote unexpected slow wear down rates for foraging diets relying on USO consumption. DISCUSSION: The low molar wear rates with age found in Baka Pygmies contrast with extensive wear rates in savanna-dwelling foragers, reflecting differences in thermal processing techniques affecting fracture toughness and grittiness of mechanically challenging foods. Our findings reveal that culture-specific dietary proclivities influence tooth wear among foraging behaviors with important implications in hominin dietary versatility and abrasive stress on chewing surfaces.

RESUMEN

Malocclusions are a misalignment or incorrect positioning of the teeth when the upper and lower jaws close. These are poorly described in the koala and can result in irregular mastication which can have lifelong effects on body condition and oral health. A total of 370 koalas from two populations in Queensland (295) and one in South Australia (75) were examined for malocclusions. The prevalence of malocclusions in South Australian free-ranging koalas, captive Queensland koalas and Queensland free-ranging koalas was 39% (44), 30% (29) and 22% (29) respectively. Four types of malocclusion were identified based on severity of misalignment of the incisor/canine region, types 1, 2, 3 and 4. Maxillary overbite measurements of the molariform teeth were determined and these anisognathic values were then used to describe malocclusions within familial relationships in captive colonies. Captive koalas with a malocclusion had narrower mandibular width that ranged between 0.5 and 1% less than the normal measurements. The specific malocclusions reported in this study affected individuals by leading to tooth rotation, mobility and erosion with inefficient mastication of food and vegetation compaction. These changes increased the oral cavity pathology, by placing animals at risk of periodontal disease. There was evidence of familial links to malocclusion types in captive animals. Therefore captive breeding recommendations should consider known koala malocclusion traits to minimise their effect on future generations.

RESUMEN

Dental topography is a widely used method for quantifying dental morphology and inferring dietary ecology in animals. Differences in methodology have brought into question the comparability of different studies. Using primate mandibular second molars, we investigated the effects of mesh preparation parameters smoothing, cropping, and triangle count/mesh resolution (herein, resolution) on six topographic variables (Dirichlet normal energy, DNE; orientation patch count rotated, OPCR; relief index, RFI; ambient occlusion, portion de ciel visible, PCV; enamel surface area, SA; tooth size) to determine the effects of smoothing, cropping, and triangle count/resolution on topographic values and the relationship between these values and diet. All topographic metrics are sensitive to smoothing, cropping method, and triangle count/resolution. In general, smoothing decreased DNE, OPCR, RFI, and SA, increased PCV, and had no predictable effect on tooth size. Relative to the basin cut off (BCO) cropping method, the entire enamel cap (EEC) method increased RFI, SA, and size, and had no predictable effect on DNE and OPCR. Smoothing and cropping affected DNE/OPCR and surfaces with low triangle counts more than other metrics and surfaces with high triangle counts. There was a positive correlation between DNE/OPCR and triangle count/resolution, and the rate of increase was weakly correlated to diet. PCV tended to converge or decrease with increases in triangle count/resolution, and RFI, SA, and size converged. Finally, there appears to be no optimal triangle count or resolution for predicting diet from this sample, and constant triangle count appeared to perform better than constant resolution for predicting diet.

RESUMEN

Background: Although there are several studies on permanent tooth wear caused by dental materials, studies concerning primary teeth are limited. Aim: To evaluate the wear of primary tooth enamel against different ceramic and composite resin materials. Settings and Design: In vitro study. Materials and Methods: We assessed five materials (n = 10 per group): monolithic zirconia (group Z), lithium disilicate glass ceramic (group L), resin nanoceramic (group R), nanohybrid composite resin (group C), and primary tooth enamel (group E). The mesiopalatal cusps of primary maxillary second molars were used as antagonists. Wear tests were performed in a dual-axis chewing simulator, and the volume loss in the antagonist tooth was evaluated using a laser scanner and three-dimensional profiling system. Statistical Analysis Used: Data were statistically analyzed using one-way analysis of variance with Tukey's post hoc tests (P < 0.05). Results: The maximum antagonist tooth wear was observed in group L (3.84 ± 0.7 mm3), followed by groups C (3.68 ± 0.76 mm3), R (3.48 ± 0.71 mm3), Z (2.66 ± 0.65 mm3), and E (1.66 ± 0.42 mm3). Volume loss was significantly lesser in group Z than in groups L and C (P < 0.05), whereas there were no significant differences among groups L, C, and R. Conclusion: Within the limitations of this in vitro study, our findings suggest that zirconia should be used for full coronal coverage in primary tooth restorations because it causes lesser antagonist tooth wear than does lithium disilicate, resin nanoceramic, and nanohybrid composite resin.

RESUMEN

OBJECTIVES: To evaluate whether the presence of non-carious cervical lesions (NCCLs) was related to the considered risk factors and to show the corresponding odds ratio in a predictive model. METHODS: The sample was 280 dentistry students. In an initial clinical examination, 140 cases were selected that presented one or more teeth with non-carious cervical wear. For each case, a similar sex and age control without any tooth with non-carious cervical lesions was selected. An occlusal examination and periodontal probing were performed in all cases and controls by skilled dentists. All the subjects answered a questionnaire referring to factors of brushing, bruxism, preferred chewing side, consumption of extrinsic acids and the presence of intrinsic acids. Data were analysed by means of univariate and multivariate logistic regression. RESULTS: Of all the study variables, only the protrusion interferences, interferences on the non-working side, the brushing force, CPITN value and the consumption of salads increase the risk of NCCLs in the univariate regression. The best predictive model was formed by the combination of CPITN variables >1, the consumption of acidic salads, self-reported bruxism, brushing force and attrition. However, it only correctly classifies 68.75% of subjects. CONCLUSIONS: This study supports the multifactorial aetiology of NCCLs, the combination of several factors being necessary to explain their presence. The risk factors that make up the predictive model are not sufficient to explain the appearance of NCCLs. Dentists should take into account all these risk factors in prevention, diagnosis and treatment.

RESUMEN

OBJECTIVES: The aim of this study was to learn more about levels of knowledge relating to erosive tooth wear and about the most desirable way of disseminating dental information among young adults. METHODS: The research was a cross-sectional study of 331 young adults (20-25 years old) attending 25 dental care practices. Participants were asked to fill out a questionnaire with questions about their background, knowledge relating to erosive tooth wear and the preferred way of acquiring information about erosive tooth wear. RESULTS: The results showed that there are gaps in the knowledge of young adults about erosive tooth wear. The knowledge score depended on educational level and dental information received in the past. The preferred way of acquiring information was chairside information from an oral health care professional complemented by tailored information in writing. CONCLUSION: There is a lack of knowledge among young adults about erosive tooth wear. They prefer to receive information from the oral health care professionals accompanied by tailored information in writing. Further research should focus on developing this tailored information in line with the advice given by the oral health care professional.

RESUMEN

OBJECTIVE:: The aim of this retrospective case-control study was to evaluate the influence of different occlusal characteristics and self-referred bruxism in the presence of noncarious cervical lesions (NCCLs). METHODS AND MATERIALS:: The participants were 280 students (140 cases and 140 controls), with an average age of 24.5 years, from six schools of dentistry in Spain. Clinical examination was carried out to record the NCCLs and the static and dynamic occlusal characteristics. The side of mastication and bruxism was collected by questionnaire. Data variables were analyzed by means of univariate and multivariate logistic regression. Odds ratios and the respective 95% confidence intervals were calculated ( p<0.05). RESULTS:: The presence of NCCLs was significantly more likely in subjects with protrusive interferences (odds ratio [OR]=1.82); with lateral interferences, especially on the nonworking side (OR= 1.77); or who were self-reported bruxists (OR=1.72). In the multivariate analysis, protrusive interferences, bruxism, age, and the presence of attrition were risk factors for the development of NCCLs. These factors resulted in a model with an area under the receiver-operating characteristic curve of 0.667 and a positive predictive value of 61.43%. CONCLUSIONS:: There was no significant relationship between most occlusal factors and the presence of NCCLs. Only bruxism, protrusive interferences, age, and occlusal wear were risk factors. The predictive model was not sufficiently explanatory. Occlusal factors alone do not appear to be sufficient to explain the presence of NCCLs.

RESUMEN

PURPOSE: To assess the clinical performance and survival of full-contour monolithic zirconia (MZ) crowns and enamel wear produced over a 1-year period. MATERIALS AND METHODS: 60 patients requiring full-coverage restorations for endodontically treated posterior teeth opposed by healthy unrestored antagonistic teeth were selected. MZ crowns were fabricated. Vinyl polysiloxane impressions of the antagonist teeth were made, and the stone casts were digitized using a 3D laser scanner. Wear of the opposing natural teeth was evaluated at baseline (1 week), 6 months, and 1 year after crown cementation. Superimposition of the follow-up scans on the baseline scans were performed to evaluate wear. Survival and function of the restorations were evaluated by the modified USPHS rating criteria at the same timeframes. RESULTS: Comparison of the baseline and the follow-up wear values was statistically tested using the paired t-test. Statistical significance was noted between the wear values at 6 months (15.5 µm) and at 12 months (16.3 µm) (p < 0.05). The Wilcoxon signed rank sum test was performed to evaluate each parameter of the modified USPHS criteria and to analyze the change in the follow-up scores of the restorations. The survival rate for the crowns was 100%. Results were classified as "excellent" over a 1-year follow up. CONCLUSIONS: MZ crowns showed promising results related to antagonist enamel wear and survival/clinical performance.

RESUMEN

OBJECTIVE: To evaluate the effect of resistance training (RT) regarding potential hazard for dental wear, tooth abfractions, temporomandibular joint disc displacement, limitation in mouth opening, and existence of cervical spine disorders. The initial study hypothesis was that extensive resistance trainees (ExRT) would suffer from the above-mentioned symptoms more often than recreational trainees (RcT). METHODS: A controlled comparative study among male gym members via questionnaires and a clinical examination. RESULTS: ExRT had a higher prevalence of teeth indentations on the tongue (26% vs. 2% p < 0.001) and a higher prevalence of tooth abfractions than RcT (28% vs. 4% p < 0.005). ExRT exhibited a higher prevalence of cervical movement limitations (p < 0.05) and inadequate posture (p < 0.001). CONCLUSION: RT by itself may not be a risk factor for disc displacement. Nevertheless, it may act as a potential risk factor for irreversible hard tooth tissue damage and contribute to neck postural and mobility impairments.

RESUMEN

O bruxismo é definido como uma atividade rítmica, repetitiva e involuntária dos músculos da mastigação caracterizado pelo ranger e/ou apertar dos dentes. Com alta prevalência em crianças, o bruxismo infantil é relatado na literatura recente, apresentando risco de danos aos tecidos dentários, demonstrando a relevância de se conhecer a etiologia, diagnóstico, epidemiologia, consequências e propostas terapêuticas para essa condição. Objetivou-se realizar revisão sistemática de literatura científica coletando dados relevantes e atuais para discutir as informações existentes. Foram realizadas buscas por livros-textos e artigos de texto completo nas bases de dados, selecionados ao todo 84 artigos e dois manuais. O bruxismo é uma manifestação de origem central, portanto, definir sua causa é um desafio, considerando seu aspecto multifatorial, comumente associado a fatores psicológicos/emocionais como estresse e ansiedade, fatores sistêmicos como distúrbios do sono e fatores locais como hiperplasias das amigdalas e adenoides, presença de vermes, dentre outros. A identificação e eliminação, quando possível, dos fatores causais podem eliminar a ocorrência do evento. Desgastes dentários podem ser sinais clínicos da ocorrência de bruxismo, todavia, podem ser sinais de eventos passados e não mais presentes desta condição, portanto, o diagnóstico deve considerar uma anamnese específica. O controle, seja por supervisão, seja por proteção, dos desgastes dentais, associado à investigação médica de fatores causais e adoção de práticas de "higiene do sono", parecem compor estratégia mais adequada para o tratamento desta condição (AU).


Bruxism is a widely studied alteration in Dentistry and other medical classes because of its multifactorial etiology. It is defined as a rhythmic, repetitive and involuntary activity of the chewing muscles characterized by teeth grinding and/or clenching. Having high prevalence in children, infant bruxism is reported in recent literature, presenting a risk of dental tissues damage, demonstrating the relevance of knowing the etiology, diagnosis, epidemiology, consequences, and therapeutic proposals for this condition. The aim of the present work is to perform a systematic review of the scientific literature collecting relevant and current data, in order to discuss existing information and disseminate it in the community of students and teachers. Thus, there were search for textbooks and full text articles in the databases, selecting altogether 84 articles and two manuals considered relevant to the study. There is no consensus in the literature on the etiology of bruxism, but psychological/emotional factors such as stress and anxiety, systemic factors such as sleep disturbances, and local factors such as tonsils and adenoids hyperplasia are the most described and at higher risk of development of bruxism. The involvement of a multidisciplinary team is fundamental for correct diagnosis and efficient treatment, reaching all causal aspect (AU).

RESUMEN

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.
