RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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).

RESUMO

Introducción: El síndrome de apneashipopneas del sueño (SAHS) es un problema mayor de salud pública que, en sus formas más graves, afecta al 3-6% de los hombres, al 2-5% de las mujeres y al 1-3% de los niños. Estudios epidemiológicos han encontrado una elevada prevalencia de bruxismo en pacientes con SAHS. Este artículo investiga la presencia de desgaste dentario en pacientes con apnea del sueño y la asociación potencial entre ambos factores. La hipótesis nula es la no asociación entre el desgaste dentario y el SAHS. Material y métodos: Se reclutaron pacientes de forma retrospectiva desde la unidad del sueño del centro que cumpliesen con los siguientes criterios de inclusión: mayores de 18 años y estudio realizado en la unidad del sueño confirmando la presencia de SAHS. Una vez reclutados, los pacientes se sometieron a una exploración dental con el fin de detectar posibles alteraciones dentales. Los parámetros dentales evaluados fueron: desgate dental (leve, moderado y severo) y causa del desgaste (atrición, erosión y abfracción). Resultados: Fueron reclutados 99 pacientes de forma consecutiva que cumplieron los criterios de inclusión anteriormente descritos. EL 46,5% de los pacientes fueron hombres con una edad media de 54±11 años. Al relacionar el grado de desgaste dentario en los diferentes grupos de pacientes con SAHS observamos que los pacientes con mayor grado de desgaste dental (severo) presentaron un IAH correspondiente a un SAHS leve en 2 casos (2,02%), un IAH correspondiente a un SAHS moderado en 6 casos (6,06%) y un IAH correspondiente a un SAHS severo en 8 casos (8,08%), siendo las diferencias entre los grupos estadísticamente significativas (Chi-cuadrado, p=0,000). Conclusiones: El desgaste dentario puede ser un indicativo de que el paciente presente enfermedades asociadas como el SAHS por lo que debe ser tomado como un síntoma y realizar las pruebas necesarias para su confirmación o exclusión


Introduction: The obstructive sleep apnea (OSA) is a major public health problem that, in its most severe forms, affects 3-6% of men, and 2-5% of women and 1-3% of children. Epidemiological studies have found a high prevalence of bruxism in patients with Osa. This article investigates the presence of dental wear in patients with sleep apnea and the association potencies between both factors. The null hypothesis is the non-association between dental wear and OSA. Material and methods: Patients were recruited retrospectively from the sleep unit that fulfilled the following inclusion criteria: Over 18 years and study performed in the sleep unit confirming the presence of OSA. Once recruited, the patients underwent a dental examination in order to detect possible dental alterations. The dental parameters assessed were: Dental wear (mild, moderate and severe) and cause of wear (attrition, erosion and abfraction). Results: 99 patients were recruited consecutively who met the inclusion criteria mentioned above. 46.4% of the patients were males with an average age between 54 +-11 years. In relation to the degree of dental wear of the different groups of patients with OSA observed that patients with higher degree of dental wear (severe) presented an AHI corresponding to a mild osas in 2 cases (2.02%), an AHI corresponding to a moderate OSA in 6 cases (6.06%) and an AHI corresponding to a severe osas in 8 cases (8,08%) the differences between the statistically significant groups (Chi-squared, p = 0,000). Conclusions: The tooth wear can be an indication that the patient presents diseases associated with the Osas so it should be taken as a symptom and perform the necessary tests for their confirmation or exclusion

RESUMO

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


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

RESUMO

INTRODUCTION: Tooth wear is described as loss of hard tooth tissue with no occurrence of dental caries or trauma. Basic Erosive Wear Examination, a new scoring system, is a partial scoring system recording the most severely affected surface in a sextant and the cumulative score guides the management of the condition for the practitioner. The objectives of this study were to determine the prevalence of tooth wear and its association with its risk factors like gender, oral hygiene, diet, general health and life style. METHODS: A cross-sectional study was done in 364 dental patients of Kathmandu Medical College. A questionnaire was filled by interview and Basic Erosive Wear Examination was done. The data so collected were entered in Statistical Package for Social Sciences. Descriptive statistical analysis and Chi-square tests were done at confidence interval of 95% and statistical significance was set at P=0.05. RESULTS: The prevalence of tooth wear was 218 (60.1%) with no significant gender difference. A significant association was observed between tooth wear and age group (P<0.01), duration of brushing (P=0.05), method of brushing (P<0.01), swishing of soft drinks before swallowing (P<0.01) and tobacco chewing (P=0.02). CONCLUSIONS: The prevalence of tooth wear in the study population was high.

RESUMO

A review of the literature on night guards left questions unanswered about the risk and possible causes of occlusal derangement linked to night guard design and use. Cases are presented where night guard use resulted in anterior open bite and associated occlusal derangement. The aetiology of the occlusal changes observed is discussed. It is concluded that adverse occlusal effects linked to the use of night guards may be found to be more common than anticipated from existing literature. Patient follow-up is essential to monitor the use and effects of night guards, and regardless of appliance type, unintended occlusal changes may result. The use and effects of partial coverage appliances require very careful monitoring. Suggestions are provided for information and written instructions to be given to patients provided with night guards and removable orthodontic retainers.

RESUMO

There is a perceived gap between dietary advice given by health practitioners and adherence to the advice by patients. We investigated whether a behaviour change technique (implementation-planning) was more effective than standard-of-care diet advice at reducing dietary acid intake using quantitative erosive tooth wear progression as an objective clinical outcome. This study was a randomised controlled, double-blind, single-centre clinical trial in the UK. Participants (n = 60) with high dietary acid intake (≥2 daily), were recruited and randomly assigned (1:1) to receive either implementation-planning or standard-of-care diet advice in a single clinical session. Questionnaires and impressions were taken at baseline and 6 months later. Dental casts were scanned using laser profilometry and superimposed using surface-matching software. Data were analysed per protocol and intention-to-treat using independent t-tests and Mann-Whitney tests. The intervention group reduced their dietary acid intake between meals to 1 intake per day compared to 2 intakes per day for the controls and demonstrated reduced dental hard tissue volume loss (-0.00 mm3 (SD = 0.01)) compared to controls (-0.07 mm3 (SD 0.17)), p = 0.049. This paper supports the use of implementation planning in clinical practice and presents a non-invasive method of intervention assessment in behaviour change. Larger trials are needed to confirm the generalisability of results.

RESUMO

PURPOSE: Evidence exists which suggests that a vegetarian diet is a predisposing factor to erosive tooth wear. The aim of this study was to assess the influence of dietary pattern (vegetarian, lacto-ovo vegetarian and omnivore) on erosive tooth wear. MATERIALS AND METHODS: Two hundred seven subjects (29 vegetarians, 96 lacto-ovo vegetarians and 82 omnivores) underwent an oral assessment and were asked to answer questionnaires about diet and oral care. RESULTS: Individuals who followed vegetarian and lacto-ovo vegetarian diets had statistically significantly more erosive tooth wear than did omnivores (p = 0.004). Conversely, omnivores presented more tooth loss than did lacto-ovo vegetarians (p = 0.027). Being a vegetarian or a lacto-ovo vegetarian entailed an increased risk (4 times and 2.5 times, respectively) of presenting erosive tooth wear than being omnivorous. CONCLUSION: Vegetarian and lacto-ovo vegetarian dietary patterns seem to favour the loss of dental structure by erosion. Vegetarian patients should thus be informed about preventive measures and treated accordingly.
