Background and Objective: Limited access to health services and low educational levels are factors in the rural population that are associated with the development of oral pathologies. However, the specific risk indicators contributing to erosive tooth wear (ETW) in these populations remain unclear. The objective of this study was to identify risk indicators associated with the prevalence of erosive tooth wear (ETW) in schoolchildren aged 8–12 years from rural and urban areas in the State of Mexico. Methods: A cross-sectional study was carried out in public schools in rural and urban areas. The prevalence of ETW was evaluated using the Basic Erosive Wear Examination (BEWE). The risk indicators studied were gastroesophageal reflux, vomiting, vitamin C, food, beverages, dental hygiene, bruxism, and hyposalivation. Logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI). Results: The prevalence of ETW was higher in the rural area (77.3%) compared to the urban area (51.2%) (p = 0.001). The odds of presenting ETW were more than twice in schoolchildren from rural areas compared to those from urban areas (OR: 2.25, 95% CI: 1.11–3.98). Risk indicators varied between rural and urban populations, with different factors such as the consumption of fresh tomato sauce, orange, tangerine, atole (artisanal corn-based drink), and teeth grinding in the rural area, and lemon, soft drink, fruit juice consumption, and the simplified oral hygiene index in the urban area (p < 0.05). Conclusions: To prevent ETW, strategies offering tailored dietary and hygiene advice should be proposed, considering the specific conditions of each geographic area. [ABSTRACT FROM AUTHOR]

Background: Extrinsic factors for erosive tooth wear (ETW) have been widely reported, but the intrinsic factors for wear remain unclear. Objectives: The aim of this study was to evaluate the factors associated with the prevalence of ETW in patients with reflux oesophagitis (RO). To prevent severe ETW with RO, factors associated with severity of ETW were also evaluated. Methods: A total of 270 patients with RO were recruited. A modified tooth wear index was used to evaluate the prevalence and severity of ETW. Salivary secretion and buffering capacity were assessed prior to endoscopy. Subjects were asked to complete a medical condition and oral self‐care questionnaire. Univariate and multivariate analyses were employed to identify factors collectively associated with the prevalence and severity of ETW. Results: A total of 212 cases were categorized as patients with ETW (148 with mild ETW and 64 with severe ETW). Multivariate analyses indicated that saliva secretion, severity of RO and proton pump inhibitor (PPI) resistance were associated with the prevalence of ETW, whereas age, BMI and severity of RO were associated with the severity of ETW. The odds ratio of saliva secretion and BMI were less than 1, meaning that higher saliva secretion resulted in a lower prevalence of ETW and lower BMI was associated with severe ETW. Conclusion: Saliva secretion, severity of RO and PPI resistance were associated with the prevalence of ETW, whereas age, BMI and severity of RO were associated with the severity of ETW. Lower saliva secretion and BMI were significant factors for ETW. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to estimate the prevalence of dental attrition in a young adult population and to explore associated factors. Method and materials: Dental students aged 18 to 40 years old with a minimum of 24 natural teeth were invited to take part in this cross-sectional study. Their demographic information, medical history, perceived stress, frequency of dietary acid intake, and frequency of oral habits were obtained through several questionnaires. Assessment of each type of tooth wear (erosion, attrition, and abrasion) was performed according to the tooth wear evaluation system (TWES 1.0). All participants underwent salivary tests. Statistical analysis was performed by chi-squared or Mann-Whitney tests and logistic regression models. Results: In total, 178 participants (88 women and 90 men) with a median age of 22 years were included and of those 74.7% (95% confidence interval [CI], 68% to 81%) had dental attrition. Univariate ana lysis revealed positive associations for male sex, age, body mass index, awake bruxism frequency, and erosive tooth wear with the presence of dental attrition. Multivariable logistic regression (Nagelkerke r2 = 0.31) indicated that dental attrition was associated with erosive tooth wear (adjusted odds ratio [aOR], 6.3; 95% CI, 2.8 to 14.2), body mass index (aOR, 1.3; 95% CI, 1.1-1.5), and age (aOR, 1.2; 95% CI 1.0 to 1.3). Conclusion: Dental attrition is present in most young adults of Catalonia. The associated factors were erosive tooth wear, body mass index, and age. Slight alterations of salivary parameters do not seem to predict dental attrition. [ABSTRACT FROM AUTHOR]

Dental wear arises from mechanical (attrition or abrasion) and chemical (erosion) factors. Despite its prevalence and clinical significance, accurately measuring and understanding its causes remain challenging in everyday practice. This one-year study with 39 participants involved comprehensive examinations and full-arch intraoral scans at the start and after 12 months. Volume loss exceeding 100 µ on each tooth's surfaces (buccal, lingual/palatine and incisal/occlusal) was measured by comparing three-dimensional scans from both time points. This study also assessed factors such as abrasion and erosion through clinical exams and questionnaires. There were no significant differences in dental wear in participants with sleep bruxism. However, noticeable wear occurred in the front teeth of those with waking bruxism and joint-related symptoms. Increased wear was associated with frequent consumption of acidic drinks, regular swimming, dry mouth, nocturnal drooling and heartburn, while no significant wear was found in patients with reflux. The used methodology proved effective in accurately assessing the progression of dental wear, which is important as many patients may initially be asymptomatic. The variability observed in dental wear patterns underscores the need to develop specific software applications that allow immediate and efficient comparison of wear areas based on extensive analysis of patient databases.

Background: Non-institutionalised older adults is the majority of older adults in Hong Kong. The study aimed to examine erosive tooth wear (ETW) and its association with dental conditions and oral hygiene habits among non-institutionalised older adults in Hong Kong. Methods: This cross-sectional study recruited dentate adults aged 60 or above from nine elderly daycare centres in the five main districts of Hong Kong. The study consists of a questionnaire survey and a clinical examination. A researcher used a questionnaire to collected the participants' demographic information, oral hygiene habits such as toothbrushing habits and dental visit behaviour. A calibrated examiner performed an oral examination in the daycare elderly centre to assess the ETW using basic erosive wear (BEWE) criteria. Oral hygiene was recorded using visible plaque index. Prosthetic status was recorded using the World Health Organization criteria. Logistic regression was used to examine the correlation between ETW and the dental conditions and oral hygiene habits. Results: This study recruited 433 dentate adults and 333 adults were female (77%). Their age ranged from 60 to 99 years and their mean age was 74 years (SD = 7). They all had ETW (BEWE > 0). Over half of them (57%) had BEWE score of 3, indicating severe ETW. Analysis showed increasing age (OR = 1.030, p = 0.029) and older adults with untreated dental caries had higher odds (OR = 1.822, p = 0.002) of presenting severe ETW. No other associations were found between the ETW and the factors studied. Conclusion: Hong Kong non-institutionalised older adults aged 60 or above had ETW and more than half of them had severe ETW. Increasing age and having untreated dental caries were associated with severe ETW. [ABSTRACT FROM AUTHOR]

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.

Background The impact of consumption of sugar-sweetened beverages (SSB) on health outcomes such as obesity have been studied extensively, but oral health has been relatively neglected. This study aims to assess the association between SSB consumption and dental caries and erosion. Methods Systematic review of observational studies. Search strategy applied to Medline, Embase, Cochrane Library, SciELO, LILACS, OpenGrey and HMIC. The risk of bias was assessed using the NIH Quality Assessment Tool for Observational Cross-Sectional Studies and evidence certainty using Grading of Recommendation Assessment Development and Evaluation. Relationships between SSB consumption and caries and erosion were estimated using random-effects model meta- and dose–response analyses. Results A total of 38 cross-sectional studies were included, of which 26 were rated as high quality. Comparing moderate-to-low consumption, there was significantly increased risk of both caries [OR = 1.57, 95% CI: 1.28–1.92; decayed, missing and filled teeth weighted mean differences (DMFT WMD) = 0.82, 95% CI: 0.38–1.26] and erosion (OR = 1.43, 95% CI: 1.01–2.03). Comparing high-to-moderate consumption, there was further increased risk of caries (OR = 1.53, 95% CI: 1.17–1.99; DMFT WMD = 1.16, 95% CI: −0.59–2.91) and erosion (OR = 3.09, 95% CI: 1.37–6.97). A dose–response gradient and high certainty of evidence was observed for caries. Conclusions Increasing SSB consumption is associated with increased risk of dental caries and erosion. Studies were cross-sectional, hence temporality could not be established, but the positive dose–response suggests this relationship is likely to be causal. These findings illustrate the potential benefits to oral health of policies that reduce SSB consumption, including sugar taxation. [ABSTRACT FROM AUTHOR]

Background: With regard to the increasing consumption rates of unhealthy beverages among adolescents, the main purpose of the present study was to determine the association between beverage intake pattern and dental caries and tooth erosion in this age group. Methods: A total sample of 600 adolescents was recruited in this study using a multistage cluster random sampling method in the city of Kerman, in the southeast of Iran, in 2017. Then, the Decayed, Missed and Filled Teeth (DMFT) index and the Tooth Wear Index (TWI) were registered for each participant. A Beverage Frequency Questionnaire was also employed to estimate typical beverage intake frequency. Correspondingly, negative binominal regression and logistic regression were performed to determine the independent variables associated with the DMFT index and the TWI. Results: The findings revealed that the highest consumed beverage in daily living was tea in both genders, followed by sweetened soft beverages, as well as milk and kefir/yogurt drink. The results of the DMFT index were also significantly different in participants that had never consumed milk compared with those who had used milk on a daily basis. Moreover, the DMFT index in participants who had never consumed sweetened soft beverages was 39%, less than those who had had a daily intake of such beverages. Also, the chance of tooth erosion for participants who had never used sweetened soft beverages was 94%, lower than that in daily consumers. Conclusions: The results of this study revealed that adolescents had an unhealthy beverage intake pattern. Furthermore, milk consumption was beneficial to dental caries, whereas use of soft drinks associated with more dental caries and tooth erosion. [ABSTRACT FROM AUTHOR]

Background. Obesity is a risk factor for several chronic diseases, and scientific evidence suggests an association between obesity and oral diseases. In this study, the authors estimated the prevalence of risk factors for caries, dental erosion, and periodontal disease in a group of obese patients referred for bariatric surgery. Methods. The authors invited obese patients who were referred for bariatric surgery at a private center for treatment of obesity to participate in this study. The patients answered a questionnaire about their sociodemographic data, general and oral health histories, dietary habits, and oral health care behavior. Results. The authors evaluated a total of 255 participants; 200 (78.4%) were women, the median (interquartile range) age was 36.0 (30.0-43.0) years, and the median (interquartile range) body mass index was 39.7 (37.6-43.5) kilograms per square meter. The authors observed a high prevalence of risk factors for dental erosion; 78.4% of the participants consumed acidic foods daily, and 92.2% consumed acidic beverages daily. With respect to risk factors for caries, 38.5% of the participants reported high sucrose intake, and 59.6% preferred sweet beverages and foods with sucrose. Almost 13% of the participants reported having or having had dental mobility, and 59.6% reported having or having had gingival bleeding, suggesting a history of periodontal disease. Conclusions. Obese patients referred for bariatric surgery are exposed to risks of experiencing oral diseases and should be evaluated by a dentist. Practical Implications. Knowing the risk factors for oral diseases in obese patients is important in raising awareness about these risk factors, as well as to prevent complications in the oral cavity.

Acidic beverage consumption is a well-recognized contributor to extrinsic dental erosion. Although the pH values of some commercially available bottled waters are below neutral pH, water is still considered to be a safe and healthy choice. Artificial flavoring liquids or powders, known as water enhancers (WEs), have been introduced to the market to modify the taste of water. The purposes of the present study were to measure the pH and titratable acidity of WEs and to perform gravimetric analysis of teeth immersed in solutions of WEs mixed with different brands of bottled water in order to determine the erosive potential in vitro. The pH and titratable acidity using 0.1M sodium hydroxide were calculated for 7 brands of WEs added to 3 brands of bottled water, which had different initial pH values. Extracted human molar teeth were submerged in each combination of solutions for gravimetric analysis. Distilled water was used as the positive control and citric acid as the negative control. Data were analyzed with 2-way analysis of variance and post hoc Tukey-Kramer testing (P = 0.05). The pH value (2.9-3.0) and titratable acidity (32.2-35.3 mmol/L hydroxide) of all of the experimental solutions were considered acidic, regardless of the WE brand. Average tooth structure loss after 1 month of immersion in the solutions was 4%, and surface changes were consistent with erosive dissolution. The results showed that adding a WE to water significantly increases the potential for dental erosion. The high content of citric acid in WEs is believed to be the cause. Patients should be advised to use WEs with caution. [ABSTRACT FROM AUTHOR]

Objectives: The objective of the study was to determine the erosive tooth wear (ETW) status of institutionalized patients for alcohol misuse rehabilitation therapy in the north of Portugal. Material and methods: Descriptive, analytical, and cross-sectional study, conducted on 277 individuals (83.4 % men) with an average age of 43.6 ± 8.4 years, institutionalized at Instituto da Droga e Toxicodependência-Delegação Regional Norte (IDT-Norte). ETW prevalence and severity were assessed by Eccles and Jenkins index. Multivariate logistic regression was used to identify ETW risk factors. Subjects with ETW risk identification according to biological and behavioral exposure were determined in the study. Results: ETW prevalence was 98.6 %. In the cohort, 51.3 % showed localized ETW lesions, 40.1 % generalized ETW lesions, and 7.2 % enamel ETW lesions, more frequently localized in maxilla. From the examined dental surfaces ( n = 15,598), 11,493 had erosive wear lesions: 92.4 % (95 % CI 91.7-93.1 %) of all occlusal surfaces, 71.9 % (95 % CI 70.7-73.1 %) of all palatal/lingual, and 56.7 % (95 % CI 55.4-58.1 %) of all buccal surfaces. Buccal and lingual surfaces showed 43.2 and 41.8 % enamel erosive wear lesions; occlusal surfaces had 43.4 % localized erosive wear lesions in dentin. The main ETW risk factors were as follows: age, gastroesophageal reflux disease over 1 year, daily intake of alcohol ≥240 g (grams), and intra-oral location in anterior region; 46.2 % of the participants had erosive risk by exposure to biological and behavioral factors. Conclusions: The ETW status showed high values for disease prevalence and severity, mainly located in the maxilla, and high frequency of erosive wear lesions at occlusal, buccal, and lingual surfaces, resulting from simultaneous exposure to several risk factors. Clinical implications: For ETW differential diagnosis, the association of both clinical and biological/nutritional/behavioral risk factors should be done for each studied population.

ABSTRACT Objectives This study aimed to evaluate whether tooth enamel bleached with hydrogen peroxide (H2O2) is more susceptible to erosion when compared with unbleached tooth enamel; and whether the presence of calcium (Ca) in the bleaching gel influenced this process. Materials and Methods Enamel blocks were prepared from human molars, and submitted to surface microhardness analysis (baseline). Blocks were prepared and randomly divided into four treatment groups ( n = 20): G1 and G2-bleached with 7.5% H2O2, with and without Ca, respectively; G3 and G4-bleached with 35% H2O2, with and without Ca, respectively. After bleaching, these groups were submitted to an erosive challenge with 1% citric acid. G5 and G6 ( n = 20, each) were the negative (without bleaching) and positive controls (without bleaching, but with erosion), respectively. The percentage of surface hardness loss (%SHL), the 3D non-contact profilometry and Scanning Electron Microscopy (SEM) analyses were performed. Results G2 showed the highest %SHL after bleaching. G1 presented the lowest %SHL in comparison with G2, G3, G4, and G6 after erosion ( p < 0.05), which was confirmed only by the SEM analysis. Conclusion It is suggested that low concentration of H2O2 with calcium can be recommended for at-home bleaching agents, which may avoid the mineral loss of bleached enamel after an erosive challenge. Clinical Significance Low concentration of H202 with calcium can be recommended for at-home bleaching agents, which may avoid the mineral loss of bleached enamel after an erosive challenge.

One of the greatest challenges to modern dentistry is the progressive destruction of tooth material due to chemical erosion. Dental erosion is the loss of dental hard tissue, without the action of bacteria, in which demineralisation of enamel and dentine results due to a decrease in intra-oral pH. The aim of this review was to appraise the scientific literature on the factors that can affect intra-oral pH. The review will examine (i) the protective role of human saliva, in terms of its mineral composition, flow rates and buffering systems and (ii) sources of in-mouth acids such as extrinsic acids, which are derived from the diet and environment, as well as intrinsic acids, which are related to disorders of the gastro-oesophageal tract. This review may assist clinicians to identify the risk factors for tooth wear and to recommend adequate preventive measures to patients. [ABSTRACT FROM AUTHOR]

For optimal athletic performance, an athlete requires good oral health to reduce the risk of oral pain, inflammation, and infection and thereby minimize the use of analgesics and antimicrobial agents. Increased intake, frequency, and dental contact time of carbohydrate-rich foods, sports nutrition products, and acidic carbohydrate-containing sports and energy drinks may contribute to risks of dental erosion, caries, and inflammatory periodontal conditions in the athlete, especially when he or she also exhibits dehydration and poor oral hygiene habits. Examining the athlete before he or she begins participating in a sport allows the dental care provider to determine the patient's existing oral health, hygiene, and susceptibility to risk factors for erosion, caries, and inflammatory periodontal disease. This oral profile, in conjunction with the individual athlete's dietary needs, can be used to establish a treatment and preventive program, including oral health education. Good oral hygiene practices and topical fluoride varnishes, must be available to the athlete. Rinsing with water or a neutral beverage after exposure to carbohydrates or acidic sports nutrition products may reduce carbohydrate contact time and bring oral pH levels back to neutral more quickly, reducing the risk of caries and erosion. Finally, the dentist should encourage the athlete to consult with an experienced sports dietitian to ensure that principles of sports nutrition are being appropriately applied for the type, frequency, and duration of exercise in consideration of the individual's oral health needs.

Research on dental erosion has largely been undertaken at room temperature despite fruit juice drinks often being consumed at elevated temperatures in the United Kingdom, notably during periods of convalesce. The aim of the study was to evaluate the erosive potential of two fruit juices containing acidic non-alcoholic drinks at elevated temperatures in situ on human enamel after 5, 10 and 15 days. A commercially available conventional apple and blackcurrant fruit juice drink was compared to a blackcurrant juice drink modified to have low erosive potential, and mineral water consumed at approximately 59 °C. Twenty-one healthy volunteers aged 18 or over participated in a single-centre, single-blind (blinded to the investigator), three-treatment crossover study. Subjects were randomised to a treatment sequence using a Latin square design. Subjects wore upper removable appliances containing one human enamel specimen from 9 am to 5 pm for 15 days for each beverage. Measurements of enamel loss were recorded after 5, 10 and 15 days by contact surface profilometry. The low erosive blackcurrant drink caused significantly less enamel loss ( P < 0·05) than the commercially available conventional apple and blackcurrant fruit juice drink and was not statistically significantly different to mineral water at any of the time points in the study. Consuming the modified low erosive blackcurrant drink at an elevated temperature resulted in negligible enamel loss in situ, consistent with room temperature findings. [ABSTRACT FROM AUTHOR]

The aim of this investigation was to give insights into the impact of endurance training on oral health, with regard to tooth erosion, caries, and salivary parameters. The study included 35 triathletes and 35 non-exercising controls. The clinical investigation comprised oral examination, assessment of oral status with special regard to caries and erosion, saliva testing during inactivity, and a self-administered questionnaire about eating, drinking, and oral hygiene behavior. In addition, athletes were asked about their training habits and intake of beverages and sports nutrition. For saliva assessment during exercise, a subsample of n = 15 athletes volunteered in an incremental running field test ( IRFT). Athletes showed an increased risk for dental erosion ( P = 0.001). No differences were observed with regard to caries prevalence and salivary parameters measured during inactivity between athletes and controls. Among athletes, a significant correlation was found between caries prevalence and the cumulative weekly training time ( r = 0.347, P = 0.04). In athletes after IRFT and at maximum workload, saliva flow rates decreased ( P = 0.001 stimulated; P = 0.01 unstimulated) and saliva pH increased significantly ( P = 0.003). Higher risk for dental erosions, exercise-dependent caries risk, and load-dependent changes in saliva parameters point out the need for risk-adapted preventive dental concepts in the field of sports dentistry.

Objective. The aims of this study were to determine the prevalence of erosion in a birth cohort at 24, 36, and 48 months and to investigate risk factors for erosion. Methods. One hundred and fifty-four children from a birth cohort were followed at 24, 36, and 48 months of age. Results. Of the 154 children examined, 0% (0/ 154), 7% (11/154), and 28% (40/154) had erosion detected for the first time at 24, 36, and 48 months, respectively (P < 0.001). A cumulative total of 51 (33%) children and 256 (8%) teeth had erosion by the age of 48 months. There were no significant associations between erosive lesions first detected at 36 months and oral hygiene behaviour, medical conditions, or dietary habits reported at the 24- or 36-month examinations (all P > 0.05). In contrast, erosive lesion first detected at 48 months was positively associated with the use of a feeding bottle reported at the 36-month examination (P = 0.026). Conclusions. The prevalence of dental erosion in young children increased with age, with clinically detectable lesions forming between 24 and 36 months of age. Erosive lesions first detected at 48 months were positively associated with the use of a feeding bottle reported at 36 months. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess the prevalence, extent, severity, intraoral distribution and risk indicators for erosive tooth wear (ETW) among 12-year-old schoolchildren from Montevideo, Uruguay. A population-based, cross-sectional survey was conducted using a representative sample of 1,136 12-year-old schoolchildren attending public and private schools. Parents answered questions on socioeconomic status and general health. Schoolchildren answered questions on dietary and oral hygiene habits. Two calibrated examiners recorded ETW on permanent teeth according to the Basic Erosive Wear Examination (BEWE) score system. Logistic regression models were performed to assess the association between the predictor variables and the prevalence of ETW (overall and severe ETW). Odds ratios (OR) and the respective 95% confidence intervals (CI) were estimated. The prevalence of ETW was 52.9%, being mild erosion (BEWE = 1) in the vast majority of cases (48.5%). Severe erosion (BEWE ≥2) was detected in 4.4% of schoolchildren. The overall prevalence of ETW differed significantly between categories of gender and socioeconomic status, but only between gender in the severe ETW analysis. The overall extent of ETW was significantly different between categories of gender, socioeconomic status, and swish before swallow. The extent of severe ETW differed between categories of swish before swallow and brushing frequency. In the logistic regression analysis, no association was found between the studied variables and the overall prevalence of ETW. Males were more likely to have severe ETW than females (OR = 3.22, 95% CI = 1.50-6.89). ETW may be considered a public health problem among 12-year-old-Uruguayan schoolchildren. © 2015 S.

The purpose of this study was to evaluate enamel wear caused by monolithic zirconia crowns and to compare this with enamel wear caused by contralateral natural antagonists. Twenty monolithic zirconia crowns were placed in 20 patients requiring full molar crowns. For measurement of wear, impressions of both jaws were made at baseline after crown cementation and at 6-month follow-up. Mean and maximum wear of the occlusal contact areas of the crowns, of their natural antagonists and of the two contralateral natural antagonists were measured by the use of plaster replicas and 3 D laser scanning methods. Wear differences were investigated by the use of two-sided paired Student's t-tests and by linear regression analysis. Mean vertical loss (maximum vertical loss in parentheses) was 10 (43) μm for the zirconia crowns, 33 (112) μm for the opposing enamel, 10 (58) μm for the contralateral teeth and 10 (46) μm for the contralateral antagonists. Both mean and maximum enamel wear were significantly different between the antagonists of the zirconia crowns and the contralateral antagonists. Gender and activity of the masseter muscle at night (bruxism) were identified as possible confounders which significantly affected wear. Under clinical conditions, monolithic zirconia crowns seem to be associated with more wear of opposed enamel than are natural teeth. With regard to wear behaviour, clinical application of monolithic zirconia crowns is justifiable because the amount of antagonistic enamel wear after 6 months is comparable with, or even lower than, that caused by other ceramic materials in previous studies.

A novel longitudinal erosion-abrasion in- situ model was proposed. In an exploratory test (phase 1) toothbrushing effect was investigated using a parallel design, whereas in the main study (phases 1 + 2), a crossover design tested the effect of fluoride dentifrice. In phase 1, 16 subjects ( n = 5-6 subjects per group) wore partial dentures with enamel specimens for 28 d and adhered to one of the following treatment regimens: regimen A, erosion only; regimen B, erosion + toothbrushing with fluoride-containing dentifrice [1,100 ppm of fluoride as sodium fluoride ( Na F)]; and regimen C, erosion + toothbrushing with placebo dentifrice (0 ppm fluoride). Erosion consisted of the exposure of specimens to grapefruit juice. In regimens B and C, toothbrushing was performed with the test dentifrices 5 min after erosion. For the main study a second phase was carried out in which subjects initially treated with regimen B were treated with regimen C, and vice versa (crossover, n = 11), repeating the same experimental protocol. Enamel wear was measured by optical profilometry at baseline and every 7 d thereafter. In the exploratory test (phase 1), no significant differences were observed among regimens at any of the study time-points. In the main study (phases 1 + 2), higher enamel wear was observed for regimen C than for regimen B. A significant trend was observed for the increase of enamel wear over time. Fluoridated dentifrice reduced the development of erosive-abrasive lesions. The proposed longitudinal model provided adequate responses for erosion-abrasion frequency and fluoride effects.

Aim To identify potential risk indicators of dental erosion ( DE) among 12- to 14-year-old Jordanian school children. Design A random cross-sectional sample was selected from Amman, Irbid, and Al-Karak governorates. A weighted multistage random sampling system was used to yield 3812, 12- to 14-year-old school children from 81 schools. The study utilized a self-reported questionnaire of factors reported in the literature and thought to be associated with DE. Full mouth recording using the tooth wear index modified by Millward et al. (1994) was performed by a single calibrated examiner. Results Logistic regression analysis defined the risk indicators that were simultaneously associated with DE with geographical location, medical condition including frequent mouth dryness, and having frequent bouts of vomiting or using a cortisol inhaler, dietary habits including consumption of carbonated beverages, lemon, sour candies, and sports drinks, keeping soft drinks in the mouth for a long time, brushing teeth following soft beverages or drinking lemon juice at bed time. Conclusions Dental erosion is a multifactorial condition in which mouth dryness, vomiting, cortisol inhaler use, keeping soft drinks in the mouth, drinking beverages at bed time, consumption of lemon, sour candies, and having confectionary as snacks are risk indicators, and area of residence are all potential factors.

The article explores the management of asthma in a dental care setting. A common, long-term inflammatory disease of the airways, asthma is associated with the hyper-responsiveness of the airway that often leads to breathlessness. In "Guidelines for the Management of Children Referred for Dental Extractions under General Anaesthesia," children with severe or poorly controlled asthma need special considerations and should be referred to hospital day care to ensure proper treatment.

BACKGROUND/OBJECTIVES:Investigations about possible correlations between vegetarian diet and periodontal conditions are rare and characterized by small case numbers. The aim of this clinical study was to investigate the influence of a vegetarian diet on periodontal parameters with an appropriate sample size.SUBJECTS/METHODS:A total of 200 patients, 100 vegetarians and 100 non-vegetarians, were included in the study. All patients were examined including a full mouth assessment of the periodontal and dental conditions. In addition, a questionnaire was handed out to ask for patients' oral hygiene habits and level of education. For statistical analysis the Mann-Whitney Test (χ2 for analysis of the questionnaire) was applied (level of significance: P<0.05).RESULTS:Well known periodontal risk factors like age, gender and smoking habits were equally distributed within each group (71 females, 29 males, respectively and 10 smokers in each group; mean age: 41.45 years vegetarians versus 41.72 years non-vegetarians). Vegetarians had significantly lower probing pocket depths (P=0.039), bleeding on probing (P=0.001), periodontal screening index (P=0.012), a better hygiene index (P<0.001) and less mobile teeth (P=0.013). Dental examinations revealed significantly less missing teeth (P=0.018) but also more decayed (P=0.001) and eroded (P=0.026) teeth in vegetarians. Furthermore, vegetarians had a higher level of education (P<0.001), but visited dentists significantly less frequent.CONCLUSIONS:Vegetarians revealed better periodontal conditions (less inflammation signs, less periodontal damage and a better dental home care). However, it should be considered that vegetarians are not only avoiding meat in their nutrition but are also characterized by an overall healthier life style. [ABSTRACT FROM AUTHOR]

The media are finally beginning to inform the general public that they are at risk for dental erosion as a result of the foods and the beverages they consume. Dental erosion or erosive tooth wear not only can be caused by extrinsic (dietary) acids but also intrinsic acids. Historically, anorexic and bulimic patients have been the population dentists have had to be aware of, but with the increasing prevalence of gastroesophageal reflux disease (GERD) in the general population, another population must be monitored. Tooth wear is usually multifactorial, and it is often difficult to assign a specific etiology; abrasion, attrition, and erosion must all be considered as potential etiologies. This critical appraisal reviews four articles looking at dental erosion and its relationship with GERD. [ABSTRACT FROM AUTHOR]

The article presents a study that examines the capacity of fruit smoothies in causing dental erosion and further investigates the level of hydrogen ion (pH) and titratable acidity in fruit smoothies to determine the effects of exposure to them upon samples of human tooth tissue. It discusses the methodology used in the study. It concludes that that regular consumption of smoothies should be avoided due to the risk of developing caries.

Objectives The aim of this study was to describe the occurrence of risk factors for dental erosion for a group of young adults who are particularly susceptible to erosion. Another aim was to describe the awareness of erosion and distribution of risk factors according to the educational background of the parents. Methods The sample ( n = 2004 individuals) was randomly drawn from the population of 19-20-year-old Norwegians. The data were collected using telephone interviews. We measured awareness about erosion using the following question: 'Have you ever heard about dental erosion?' We obtained information about the frequency of intake of the following risk factors: soft drinks with and without sugar, and juice. Soft drinks with sugar included lemonade (Coca-Cola, Solo, Pepsi, Mozell and ice tea) and sport drinks ( XL1, Maxim). Soft drinks without sugar included Cola light, Zero, PepsiMax, Solo light and ice tea light. Juice included orange, grapefruit, apple and kiwi juice. The parents' level of education was based on the Norwegian school system, which has three levels: compulsory schooling (10 years), upper secondary school education (up to 13 years) and university/college education. The data were analysed using logistic regressions analyses. Results Awareness of erosion was high - 93.5% of respondents were aware of the problem. The majority of respondents believed that erosion can be prevented - altogether 84.9%. They also believed that soft drinks with and without sugar are equally important for the development of erosion. 17.5% of respondents drank soft drinks with sugar daily or several times a day. The corresponding figures for soft drinks without sugar and juice were 4.9% and 34.1%, respectively. Young adults with mothers with high education drank soft drinks both with and without sugar less frequently than those who had mothers with low education. This pattern was the opposite for juice. Conclusion Consumption of soft drinks and juice is high, even though awareness and knowledge about the causes of erosion are widespread. This indicates the need for effective intervention strategies to reduce the level of consumption. These strategies should take into account the fact that the distribution of risk factors is skewed with respect to parents' level of education. [ABSTRACT FROM AUTHOR]

Background: Dental erosion is an increasingly prevalent problem in Australia, with the consumption of sports beverages suggested as a risk factor. The aim of this study was to compare the erosive potential of Australian sports beverages. Methods: Ten beverages were selected and analysed to determine their pH, titratable acidity and apparent degree of saturation with respect to apatite. The erosive potential of the beverages was measured by human enamel surface loss and surface softening following a 30-minute exposure. A taste testing panel was established to determine the palatability of the sports beverages. Results: All sports beverages except Sukkie and Endura produced substantial surface loss and surface softening. Compared with the other sports beverages, Sukkie and Endura had a higher pH, lower titratable acidity and higher calcium content. However, Sukkie and Endura were deemed to be less palatable than the other more acidic sports beverages. Conclusions: The majority of the sports beverages tested produced dental erosion in this in vitro model. However, two new products Sukkie and Endura have lower erosive potential but also lower palatability. [ABSTRACT FROM AUTHOR]

Background: Some diet factors are risk factors for dental erosion. Methods: We performed computer searches of PubMed, Cochrane Library, EBSCO, CALIS, et al., to search for studies investigating risk factors for dental erosion. For risk factors investigated in a comparative way, we computed pooled odds ratios (ORs) using the Mantel and Haenszel method. Results: A total of 9 studies met the inclusion criteria, and 6 risk factors were considered, including soft drinks, sports drinks, juice, vitamin C, milk, and yoghourt. The following associations were found for soft drinks (OR = 2.41, 95%CI = 2.03-- 2.85) and vitamin C (OR = 1.16, 95%CI = 1.10--1.22). While juice (OR = 0.90, 95%CI = 0.25--3.24), sports drinks (OR = 1.58, 95%CI = 0.88--2.85), milk (OR = 0.67, 95%CI = 0.11--4.01), and yoghourt products (OR = 1.05, 95%CI = 0.28--3.96) were not associated with dental erosion. Conclusions: This meta-analysis provides comprehensive evidence-based assessment of diet-related factors for dental erosion. Preventive strategies should be taken to reduce dental erosion.

International Journal of Paediatric Dentistry 2011; 22: 68-76 Background. The change towards a more Westernised diet in Libya may increase the risk of caries and erosion in children. Aims. To investigate any association between dental caries, dental erosion, and potential dietary risk factors in Libyan schoolchildren. Methods. A random sample of 791 schoolchildren aged 12 years underwent dental examination for caries and erosion and completed a questionnaire to provide dietary data. Dental caries was assessed using the WHO (Oral Health Surveys: Basic Methods, 1997) criteria. Erosion was assessed using UK National Diet and Nutrition Survey (NDNS, Young People Aged 4-18 years. Volume 2: Report of the Oral Health Survey, 2000) criteria. Associations between caries and dietary variables were investigated through bivariate and multivariate analyses. Results. Of the 791 12-year olds, 57.8% (457) had caries experience and 40.8% (323) had experience of erosion. One hundred and ninety-two subjects (42%) of the subjects with caries experience also had erosion, whilst 131 subjects (39.2%) of the 334 without caries had clinical signs of erosion ( P = 0.464; OR, 1.123; 95% CI, 0.842, 1.497). There was no statistically significantly relationship between dental caries and dental erosion. Frequency of consumption of fruit-based sugared drinks was statistically significantly positively associated with experience of caries ( P = 0.002). Conclusions. Dental caries experience was associated with frequency of consumption of sugared dietary items but not with dental erosion. [ABSTRACT FROM AUTHOR]

Aim. To evaluate tooth surface loss (TSL) severity and associated risk factors in a representative sample of Saudi adults. Materials and Methods. Four hundred TSL patients (200 females and 200 males) participated in this study. Each patient completed a comprehensive questionnaire interview (using a modified Tooth wear Assessment Questionnaire) and then examined for the severity of TSL (using ordinal scale). Results. Seventy-five percent of participants demonstrated attrition, 90% had erosion, 15% had abrasion, and 95% had more than one type of TSL. The most common risk factors were consumption of acidic food/drinks (78%), parafunctional habits (70%), and unilateral chewing (50%). 77% of participants demonstrated grade 2 TSL. Males demonstrated greater TSL severity (P = 0.05). Age, systemic disease, number of remaining teeth, acidic food/drinks, bruxism/parafunction, biting objects, facial pain/tenderness, sour taste, exposure to dust, unilateral chewing, using dental abrasives, and brushing frequency/technique had significant relationship with TSL severity (P = 0.05). Conclusions. TSL has a multifactorial aetiology. Parafunction, gastrointestinal problems, and diet were the most common aetiological factors reflecting changes to stressful modern life-styles, eating/drinking habits, and behaviours. Gender didn't influence the aetiology of TSL; however males demonstrated more TSL severity. Patients' age had significant correlation to TSL severity. [ABSTRACT FROM AUTHOR]

International Journal of Paediatric Dentistry 2011; 21: 451-458 Background. The prevalence of dental erosion seems to be rising in young populations, particularly among individuals of higher socioeconomic status. Aim. To assess the prevalence and associated factors of dental erosion in children and adolescents of a private dental practice. Design. A total of 232 participants, aged 2-20 years, were examined. Dietary habits, oral hygiene, and medical data were collected from dental records. Logistic regression analyses were conducted. Results. Dental erosion prevalence was of 25.43% and was highest on the occlusal surfaces (76%). Associated factors were: frequent consumption of soft drinks (OR = 2.33; 95% CI = 1.01-5.38) and candies (OR = 3.23; 95% CI = 1.25-8.32); and interaction between these two factors (OR = 3.95; 95% CI = 1.60-9.75). On anterior teeth, associated factors were: frequent consumption of fruits (OR = 2.53; 95% CI = 1.09-5.91); and age (OR = 1.07 95% CI = 1.01-1.14). Milk consumption was associated with a lower prevalence of dental erosion (OR = 0.40; 95% CI = 0.17-0.94). Conclusions. A relatively high prevalence of erosion was found in association with frequent intake of soft drinks, candies, and fruits. The consumption of milk seemed to protect against dental erosion on anterior teeth. [ABSTRACT FROM AUTHOR]
