Tooth Erosion Awareness in a Brazilian Dental School

Practical training using BEWE aimed at improving the diagnosis ability of erosive tooth wear for dental students-A randomized trial

INTRODUCTION

Erosive tooth wear (ETW) has been gaining attention due to its high prevalence. However, ETW clinical diagnosis is difficult and may go unnoticed by many professionals. The present study aimed to develop, implement and evaluate a theoretical-practical training using active methodologies in the development of undergraduate students' skills for the diagnosis of ETW compared to the traditional teaching method.

MATERIALS AND METHODS

This randomized controlled study involved two parallel groups: control group (n = 22), with learning based only on theoretical content and test group (n = 24), learning by theoretical-practical activity mediated by monitors/tutors. The theoretical class covered the current concepts of ETW, aetiology, diagnosis, use of the BEWE index, prevention and treatment. The practical training included exercises and discussions based on the diagnosis using BEWE scores of a collection of images and extracted teeth. To evaluate the efficacy of the teaching-learning methods, a theoretical multiple-choice questionnaire and a practical test using images and extracted teeth were applied. The outcome was the number of correct answers. Groups were compared by Mann-Whitney (theoretical knowledge) and T tests (practical ability in diagnosis) (p < .05).

RESULTS

There was no significant difference between groups in the theoretical evaluation (p = .866). The test group showed higher ability to diagnose ETW lesions compared to the control group in the practical tests (p = .001). The performance of ETW diagnosis was similar when images were used in comparison to extracted teeth (p = .570).

CONCLUSION

The practical activity associated with theoretical classes can be a promising strategy to improve the development of undergraduate students' skills in the diagnosis of ETW.

Tooth Wear Evaluation System 2.0-Evaluation of diagnostic reliability in the assessment of signs and symptoms for tooth wear by non-experts

BACKGROUND

Tooth wear is a multifactorial condition that manifests through various signs and symptoms. These individual signs and symptoms were described in multiple studies, leading to the inclusion in TWES 2.0 (Tooth Wear Evaluation System 2.0) and the forthcoming DC-TW (Diagnostic Criteria for Tooth Wear). However, a study evaluating their reliability has yet to be conducted.

OBJECTIVE

The aim of the study was to examine the reliability in the assessment of 6 signs of pathological tooth wear and 18 clinical signs and symptoms determining aetiology, all of which are included in the TWES 2.0/DC-TW.

METHODS

48 dental students (operators) evaluated patient cases from a patient pool of 14 patients on dental casts and high-resolution intraoral photographs. The agreement between all operators for each sign and symptom was calculated based on ICC (Intraclass Correlation Coefficients). Additionally, the agreement of each operator's evaluation with a predefined sample solution was calculated based on Cohen's kappa.

RESULTS

Inter-user agreement ranged from near perfect (0.91) to poor (0.02) for the various pathology signs or aetiology symptoms of tooth wear (mean 0.32). The agreements of the operator's ratings compared to the sample solution resulted in Cohen's kappa from 0.18 to 1 (mean 0.59) for the pathology signs and ranged from 0.02 to 0.51 for the aetiology signs (mean 0.38).

CONCLUSIONS

The reliability of the signs and symptoms examined and the ability of individual investigators to correctly identify and assign signs and symptoms varied widely. The current assessment tools for the qualification of tooth wear need further refinement, and examiners need intensive training in tooth wear assessment.

Awareness and knowledge of dental erosion and its association with beverage consumption: a multidisciplinary survey

BACKGROUND

Erosive tooth wear has significant impacts on oral and general health. This study aimed to measure the awareness of dental erosion to establish the relationships among sociodemographic factors, awareness and knowledge of dental erosion, and beverage consumption behaviours, in a sample of university students in Australia.

METHODS

All undergraduate students enrolled in the targeted programs at an Australian University were invited. A total of 418 students consented to participate. Each was assessed with an online questionnaire.

RESULTS

The awareness rate of dental erosion was 92.1%. Soft drinks and fruit juice were most often perceived as acidic beverages by the respondents. The students of greater age, and studying pharmacy, paramedicine, physiotherapy or science, were less likely to be aware of dental erosion. Those students that were aware of dental erosion also had better knowledge of dental erosion, which was associated with a reduced quantity of daily acidic beverage consumption as well. The students that predominantly resided overseas had less knowledge of dental erosion. The students that were of greater age, that were studying clinical science, pharmacy, medical science, paramedicine, or science, and that correctly identified more types of acidic beverages, more often consumed acidic beverages in high-risk patterns.

CONCLUSIONS

Erosive tooth wear is a relevant matter in dentistry, nutrition and public health. Within a university setting, the effect of education on oral health literacy and beverage consumption behaviour is confirmed. Dental and health professionals should actively educate the individuals and communities about dental erosion and motivate them to change acidic beverage consumption behaviours.

Knowledge on and treatment practices of erosive tooth wear among Finnish dentists

OBJECTIVES

To investigate Finnish dentists' knowledge on and means of recording, detecting and diagnosing erosive tooth wear (ETW). Treatment options and possible differences in treatment decisions between general and specialized dentists were also evaluated.

MATERIALS AND METHODS

An electronic questionnaire was sent by e-mail to 3664 Finnish dentists. Respondents' gender, age, work experience, field of specialty, and practice location were requested. The questionnaire also included a patient case where the dentists were asked about their choice of treatment. Statistical analyses were performed using means, proportions, and cross tabulations.

RESULTS

Response rate was 24% (n = 866). Almost all respondents (98.0%) recorded ETW in patient files, but only 4.1% used a detailed scoring system. Of the respondents, 64.4% usually found the cause of ETW. Use of carbonated beverages (84.3%), energy drinks (57.0%), and reflux disease (53.1%) were reported to be probable causes. The majority of the respondents (80.9%) usually assessed patient's dietary history while 1.9% evaluated saliva secretion rate. When asked about treatment decisions of ETW patients, the differences between general dentists and specialized dentists were not as obvious as hypothesized.

CONCLUSIONS

This study suggests that the Finnish dentists who participated in this survey are able to detect and/or diagnose erosive tooth wear, but there is variation in recording it. The differences in treatment decisions between general dentists and specialized dentists seem to be moderate. The treatment practices for ETW are not established and further research to create clinical guidelines seems to be needed.

Diagnosis, risk assessment, and treatment decisions for tooth wear in daily practice: a case presentation survey among Belgian dentists

This survey assessed the use of current concepts for tooth wear diagnosis, risk assessment, and treatment decisions in daily practice, and identified factors of significance for treatment decisions. A total of 104 dentists were presented with 10 cases representing varying degrees of tooth wear. The dentists were asked to answer six questions pertaining to the diagnosis, risk assessment, and treatment of each case. A benchmark was established by three experts and the agreement between dentists and the benchmark was calculated. At dentition level, the agreement was moderate for diagnosis (κ = 0.55) and risk assessment (κ = 0.54). At tooth/surface level, the agreement for clinical and radiographic severity of wear was moderate (κ = 0.57) and substantial (κ = 0.65), respectively. The agreement for treatment decision was fair (κ = 0.35). Multivariate logistic regression analysis showed that treatment decisions for operative treatment were associated with moderate to high case risk (OR = 10.1; 95% CI: 5.4-18.9). Belgian dentists performed reasonably well in applying current concepts and strategies for tooth wear diagnosis and risk assessments at dentition level, as well as for assessment of wear severity at tooth/surface level. Improvement is warranted concerning treatment decisions. This survey could be a useful tool for disseminating and improving current knowledge of tooth wear, and for training dentists in daily practice.

Awareness and Treatment Decisions on Tooth Wear among Jordanian Dentists and Prosthodontists: A Cross-Sectional Survey Study

Objectives

To assess the awareness, knowledge, and treatment decisions by dentists in Jordan regarding tooth wear.

Materials and Methods

A questionnaire was disseminated to a random sample of 200 general dentists and 100 prosthodontists working in the Ministry of Health, academia, private practices, and military services. Chi square and independent t-tests were performed for statistical analysis.

Results

Hundred and seventy-nine dentists and prosthodontists responded (59.7% response rate), of which 71.5% was females. 83.8% of the dentists reported they see patients with tooth wear. 61.5% registered wear lesions in the patient file, and 68.2% reported they find a probable cause of tooth wear. 87.2% of the dentists reported that bruxism is the most common cause in Jordan. 63.3% dentists treated their patients. 46.4% reported they “always” record a dietary history. 77.7% did not think that tooth wear is linked to caries. Low confidence levels were demonstrated among general practitioners in diagnosing and treating tooth wear. Regarding treatment decisions, most dentists decided to restore worn teeth with composite and to construct a night guard. Minimally affected anterior teeth were mostly treated with fluoride. Restoration of posterior worn teeth with overlay was suggested by one-third of the dentists.

Conclusion

The dentists and prosthodontists in Jordan are aware of tooth wear. However, examination and documentation were given a little priority by general dentists. On the other hand, there was an agreement among the dentists and prosthodontists on applying the minimally invasive approach. Clinical Significance. It is challenging for dentists to make the best treatment decision for tooth wear especially as no standard treatment is available. Therefore, this study investigated the awareness and treatment decisions of a sample of dentists and prosthodontists in Jordan.

Knowledge of and attitudes towards erosive tooth wear among students of two Chinese universities

Background

To assess the knowledge of and attitudes towards erosive tooth wear among dental, medical, and non-medical university students of two Chinese universities.

Methods

A questionnaire containing 15 questions on knowledge of erosive tooth wear and 10 questions on attitudes towards erosive tooth wear was designed, and its psychometric properties (reliability and validity) were analysed in a pilot study (n = 120 students). The following 3 groups of university students (n = 635) were recruited based on a convenience sampling technique and were distributed the questionnaire via an online survey system: dental students (DSs), medical students (MSs), and non-medical students (NSs). Differences in the scores between groups and genders were analysed by one-way analysis of variance (ANOVA). The Pearson correlation coefficient was used to determine the association between the knowledge and attitude scores (P < 0.05).

Results

The questionnaire was found to be reliable, valid and reproducible. A total of 435 students participated in this study (response rate: 69.6%). The knowledge score of the DSs (11.5 ± 3.4) was significantly higher than those of the NSs (5.5 ± 4.0) and MSs (6.1 ± 4.0) (P < 0.001). The attitude score of the DSs (45.2 ± 6.5) was significantly higher than those of the NSs (41.1 ± 6.9) and MSs (41.8 ± 6.4) (P < 0.001). The majority of DSs expressed attitudes that were more accurate and positive than those expressed by the other 2 groups. The attitude score was positively correlated with the knowledge score (r = 0.237, P < 0.001).

Conclusions

Dental students had more accurate knowledge of and more positive attitudes towards erosive tooth wear than medical and non-medical students. In this population, a positive correlation was established between knowledge of and attitudes towards erosive tooth wear.

Erosive wear of the primary dentition: who is aware of it?

AIM

To determine the influence of erosive tooth wear in the primary dentition on parental perceptions of oral health.

METHODS

This cross-sectional study involved a standardised clinical examination of 775 preschool aged children and a parent-administered questionnaire. Erosive tooth wear was measured using the Basic Erosive Wear Examination Index.

RESULTS

71% and 81% of 3 (n = 256) and 5 year-old children (n = 337) respectively exhibited signs of erosive tooth wear. Prevalence was influenced by region (p = 0.049) (p = 0.007) in both age cohorts (χ², p < 0.05) respectively and by parental level of education (p = 0.012) in the 5-year-old cohort. Parental perception of oral health was significantly associated (χ², p < 0.05) with parental level of education in the 5-year-old cohort and with the presence of dental caries, reports of pain and dental appearance of the child in both age cohorts. Parental perceptions were unaffected by the degree of erosive tooth wear their child exhibited (p = 0.0564), (p = 0.739) in both age cohorts respectively.

CONCLUSIONS

Erosive dental tooth wear is increasingly observed in the primary dentition however is not perceived as an oral health issue by parents. Its diagnosis and management therefore, fall heavily within the remit of the dental practitioner.

Awareness and knowledge of dental erosion among Yemeni dental professionals and students

BACKGROUND

This study explored Yemeni dentists' and dental students' knowledge about the associated factors, approaches to diagnosis and preventive methods of dental erosion (DE), as well as any associations between DE awareness and some potentially related variables.

METHODS

A self-administered questionnaire was distributed to general dental practitioners (n = 323) in Sanaa and to fifth year dental students (n = 97) at the University of Science and Technology, Sanaa, Yemen during the period from July to November 2013. Descriptive and logistic regression analyses were conducted.

RESULTS

Overall response rate was 79 %. Results indicated that 61 % of respondents learned about DE from dental school, 27 % from their own studies and the rest from continuing education courses and the media. DE was reportedly most frequently seen on incisors by 46 % of respondents and on premolars and molars by 24 %. While 48 % reported DE to be more common in male patients, no gender differences were reported by 20 % of respondents. Acidic drinks were believed to be causative factors for DE by 41 % of dentists and 52 % of students, while 90 % of respondents believed that patients' dietary history is important during DE diagnosis. As preventive measures for DE, reduction of acidic drink consumption was advised by 51 % of respondents while only 37 % advised their patients to use fluoridated toothpastes. Younger respondents (≤35 years) were more likely to identify the commonly-known causative factors for DE (P = 0.024). Twenty-seven percent of the respondents reportedly used an index to grade DE. Dental students were more likely than dentists to use such an index (P <0.001) and to more frequently advise their patients to reduce intake of acidic drinks (P = 0.02) compared to dentists.

CONCLUSIONS

In-depth knowledge about causative factors, diagnosis and preventive methods of DE was apparent among only half the respondents and approaches to early diagnosis were insufficient. There would appear to be an urgent need for enhancing awareness and knowledge about DE within the Yemeni dental community.

Eating disorder risk behavior and dental implications among adolescents

OBJECTIVE

To compare the occurrence of tooth erosion (TE) and dental caries (DC) in adolescents with and without risk behavior for eating disorders (EDs).

METHOD

A controlled cross-sectional study involving 1,203 randomly selected female students aged 15-18 years was conducted in Brazil. Risk behavior for EDs was evaluated through the Bulimic Investigatory Test of Edinburgh and dental examinations were performed.

RESULTS

The prevalence of risk behavior for EDs was 6%. Twenty adolescents (1.7%) were identified with severe risk behavior for EDs and matched to 80 adolescents without such risk. Among the severe risk group, 45% of adolescents were affected by TE and 80% by DC compared with 8.8 and 51.3%, respectively, in the matched group. Adolescents with severe risk had higher chances for TE (OR = 10.04; 95% CI = 2.5-39.4).

DISCUSSION

In this study, a severe risk behavior for EDs was significantly associated with TE, but not with DC.

Awareness and attitudes related to dental erosive wear among 18-yr-old adolescents in Oslo, Norway

The aim of the present study was to describe awareness and attitudes related to dental erosive wear among 18-yr-old adolescents in Oslo and to explore attitudinal differences between participants with and without the condition. All 18-yr-old subjects scheduled for their routine examination at the Public Dental Service clinics during 2008 (n = 3,206) were invited, and 1,456 agreed to participate (a response rate of 45%). The data were collected using structured questionnaires and by clinical examination of the participants. Dental erosive wear was assessed using a pictorial manual - the Visual Erosion Dental Examination scoring system - as a guide. Overall, 88% of participants had heard about dental erosive wear; however, of participants with erosive lesions only 56% were aware of, and only 47% could recall their dentist mentioning, the condition. Participants with erosive wear were more likely to have low or moderate positive attitudes towards acidic drink consumption and to be reluctant to change. In multivariate analyses controlling for gender and behavioural variables, weak or moderate positive awareness of acidic drinks remained significantly associated with higher erosion risk. This study emphasizes the importance of assessment and understanding of awareness and attitudinal aspects in relation to dental erosive wear.

Opinions on Dental Erosive Lesions, Knowledge of Diagnosis, and Treatment Strategies among Norwegian Dentists: A Questionnaire Survey

This study aimed to investigate dentists' general experience, knowledge about diagnosis, and treatment of dental erosive wear in young adults. A questionnaire was sent to 1262 Norwegian public dental health-employed dentists. The response rate was 60%. Results indicated that most dentists recorded erosive wear, half of them used a specific scoring system, and half registered lesions at the tooth surface level. Lesions were reported most often on palatal surfaces of upper anterior teeth (79% of dentists), on occlusal surfaces of lower 1st molars (74%), and on upper 1st molars (32%). Half the dentists used clinical photographs for documentation and 60% made study models. While 40% reported more erosive lesions in males, 36% reported no gender differences. High intake of carbonated beverages and acidic juices were reported as the most common cause by 97% and 72% of the dentists, respectively. Only 21% of dentists recorded the patient's dietary history, and 73% never measured saliva secretion. The majority (78%) of the dentists treated patients with erosive wear themselves. In general, the survey suggests that the dentists are relatively up to date regarding the clinical recording, diagnosis, and treatment of dental erosive wear. However, dietary and salivary analyses were not given priority, and early, preventive treatment was lacking.
