Proteome of the 2-h in vivo Formed Acquired Enamel Pellicle of Adolescents with Erosive Tooth Wear, Caries, or Sound

Introduction: Acquired pellicle (AP) acts as a membrane preventing acids from coming into direct contact with the tooth. Possibly, individuals with different dental health status present changes in its composition that could disrupt this function. Thus, the aim of this study was to compare the protein composition of the AP in adolescents with erosive tooth wear (ETW), caries, or sound. Methods: Calibrated examiners in BEWE index and ICDAS-merged Epi criteria assessed ETW and caries in a sample of 454 systemically healthy adolescents aged 12–15 years old. Thirty subjects from that sample were selected for this study: ETW group (n = 10; total BEWE ≥9 and absence of dentinal caries lesions); caries group (n = 10; total BEWE <9 and with at least one dentinal caries lesion), and sound group (n = 10; total BEWE <9 and absence of dentinal caries lesions). Two-hour-formation AP samples were taken from buccal, occlusal/incisal, palatal/lingual tooth surfaces. Protein composition was analysed by liquid chromatography-tandem mass spectrometry. Using mean reporter ion values, relative abundances of proteins were compared among the three groups to calculate for fold changes. Twofold protein increases or decreases were reported (t test, p < 0.05). Gene Ontology (GO) of included proteins was assigned. Results: Mean age of participants was 13.1 ± 1.14 years and 56.6% were females. The prevalence of ETW was of 66.6% and of dentinal caries of 33.3%. The GO analyses showed that the majority of detected proteins were stress response related. The ETW group disclosed upregulated relative abundance of antileukoprotease (2.85-fold in ETW vs. sound and 2.34-fold in ETW group vs. caries group); histatin (2.42-fold in ETW group vs. sound group and 2.20-fold in ETW group vs. caries group), and prolactin-induced protein (2.30-fold in ETW group vs. sound group and 2.06-fold in ETW group vs. caries group) (p < 0.05). Hemoglobin subunits alpha (HBA) and beta (HBB) showed decreased relative abundances in the ETW and caries groups when compared to the sound group (HBA: 0.42-fold in ETW group and 0.40-fold in caries group; HBB: 0.45-fold in ETW group and 0.38-fold in caries group; p < 0.05). Conclusion: AP from individuals with ETW showed differences when compared to other dental conditions, with relative abundance increasing of some stress response-associated proteins in ETW and a decrease in proteins related to salivary protection against acid challenges.

Erosive Tooth Wear and Associated Risk Indicators in Schoolchildren from Rural and Urban Areas of the State of Mexico: A Cross-Sectional Study.

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. 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). 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). To prevent ETW, strategies offering tailored dietary and hygiene advice should be proposed, considering the specific conditions of each geographic area.

Dental Erosive Wear Assessment amongst Different Age Groups Utilising Basic Erosive Wear Examination: An Epidemiological Study

Introduction: The study aims to assess the prevalence of erosive tooth wear and risk levels amongst different age groups utilising Basic Erosive Wear Examination (BEWE) amongst the population of South West Coastal India. Materials and Methods: One hundred and sixty healthy people participated in the research (n = 32 per group). Using sextants and the BEWE, index (0–18) allowed for the evaluation of erosive tooth wear. Questionnaires supplemented clinical data. Each participant was assigned to groups based on the severity of their erosive wear: high (BEWE sum ≥ 14), moderate (BEWE sum 9–13), low (3–8) and none (0–2). Results: There is no significant difference in the degree of erosive tooth wear across different age groups (χ2– 20.11, P – 0.067 [not-significant]). There is a significant difference in response to questions across different age groups (χ2 – 487.21, P – 0.01 [significant]). Conclusion: The prevalence of erosive tooth wear grows as individuals age. Older age groups, patients who are at a higher risk level require a more comprehensive form of treatment. The aetiology of dental erosion remained unknown to the patients, indicating a deficiency in their understanding of erosive tooth wear.

Factors associated with prevalence and severity of erosive tooth wear in patients with reflux oesophagitis.

Extrinsic factors for erosive tooth wear (ETW) have been widely reported, but the intrinsic factors for wear remain unclear. 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. 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. 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. 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.

Risk indicators for the severity of erosive wear in deciduous dentition of Mexican schoolchildren aged 5 to 7 years.

The objective of this work was to estimate the prevalence and severity of erosive tooth wear (ETW), and to identify risk indicators of deciduous dentition of a group of schoolchildren from public schools in Tlalnepantla de Baz, State of Mexico. A cross-sectional study was carried out in 352 schoolchildren from 5 to 7 years old. The severity of the ETW was evaluated using the Basic Erosive Wear Examination (BEWE). Risk indicators were evaluated through a survey which included food and beverage consumption, consumption habits, vitamin C consumption, gastroesophageal reflux, heartburn, belching, xerostomia, vomiting and teeth grinding. Multinomial logistic regression models were fitted. The prevalence of ETW was 99.7% (n = 351). Regarding severity, 46.6% were at a null/mild level, 27.3% moderate, and 26.1% severe. Males were more likely to present severe ETW (odds ratio (OR) = 2.23, 95% confidence interval (CI), 1.27-3.93; p = 0.005). The risk indicators for the severity of ETW were the frequent consumption of citrus fruits (OR = 2.09, 95% CI, 1.12-3.89; p = 0.021), fruit juice (OR = 1.99, 95% CI, 1.06-3.75; p = 0.033), processed beverages (OR = 2.15, 95% CI, 1.23-3.78; p = 0.008) and hot sauce (OR = 1.82, 95% CI, 1.03-3.20; p = 0.036). The prevalence of ETW in the deciduous dentition was very high (99.7%) and ~1/3 for severe ETW. The dietary factors associated with severe ETW are part of the regular consumption of Mexican school-age children, which impact their oral health condition. It is important to establish intervention strategies from the infant stage, focused on both children and their caregivers.

Fluid Intake and the Occurrence of Erosive Tooth Wear in a Group of Healthy and Disabled Children from the Małopolska Region (Poland).

Background: The aim of this study was to analyse the relationship between the type and amount of fluid intake and the incidence of erosive tooth wear in a group of healthy children and children with disabilities. Methods: This study was conducted among children aged 6-17 years, patients of the Dental Clinic in Kraków. The research included 86 children: 44 healthy children and 42 children with disabilities. The prevalence of erosive tooth wear using the Basic Erosive Wear Examination (BEWE) index was assessed by the dentist, who also determined the prevalence of dry mouth using a mirror test. A qualitative-quantitative questionnaire on the frequency of consumption of specific liquids and foods related to the occurrence of erosive tooth wear, completed by the children's parents, was used to assess dietary habits. Results: The occurrence of erosive tooth wear was determined for 26% of the total number of children studied, and these were mostly lesions of minor severity. The mean value of the sum of the BEWE index was significantly higher (p = 0.0003) in the group of children with disabilities. In contrast, the risk of erosive tooth wear was non-significantly higher in children with disabilities (31.0%) than in healthy children (20.5%). Dry mouth was significantly more frequently identified among children with disabilities (57.1%). Erosive tooth wear was also significantly more common (p = 0.02) in children whose parents declared the presence of eating disorders. Children with disabilities consumed flavoured water or water with added syrup/juice and fruit teas with significantly higher frequency, while there were no differences in quantitative fluid intake between groups. The frequency and quantity of drinking flavoured waters or water with added syrup/juice, sweetened carbonated, and non-carbonated drinks were associated with the occurrence of erosive tooth wear for all children studied. Conclusions: The group of studied children presents inappropriate drinking behaviours regarding the frequency and amount of beverages consumed, which, especially in a group of children with disabilities, may contribute to the formation of erosive cavities.

Prevalence of Erosive Tooth Wear and Associated Dietary Factors among a Group of Finnish Adolescents

The aim of this study was to investigate the prevalence and severity of erosive tooth wear (ETW) among Finnish adolescents and to evaluate how frequency as well as amount of the use of erosive products is associated with ETW. The study population consisted of 328 voluntary, >15-year-old secondary school students (males 49.1%, females 50.9%) in three municipalities in Finland. Clinical examination to measure ETW (BEWE index) was carried out by trained and calibrated dentists. Piloted questionnaires included questions on consumption of drinks, fruits and berries, as well as tooth brushing frequency. Means and medians of frequencies and amounts of consumed erosive products were calculated and associations with ETW severity were analysed by logistic regression models. One-third (36.9%) of the participants were in need of at least preventive measures for ETW (BEWE sum score ≥3), but severe ETW (BEWE sum score >9) was rare (2.1%). Boys had severe ETW significantly more frequently than girls (p < 0.001). Habitual consumption of erosive drinks was common especially among boys compared to girls (p = 0.001). ETW was significantly associated with the amount of consumed erosive drinks, fruits, or berries. The prevalence of ETW among adolescences in Finland seems to be at the same level as in other Nordic and European countries. Consumption of erosive products is common and thus, the risk for tooth erosion is high, especially in boys. In addition to erosive drinks, also berries and fruits are associated with ETW and should be included in individual dietary counselling when early signs of ETW are clinically detected.

Association between gastric reflux, obesity and erosive tooth wear among psychiatric patients.

The prevalence of erosive tooth wear and obesity are high in psychiatric patients and soft drink consumption is a common risk factor associated with both diseases. This study aimed to assess the association between soft drink consumption, gastric reflux, erosive tooth wear, and obesity among resident patients at the Psychiatric Hospital, Taif, Saudi Arabia.This descriptive, cross-sectional study included 223 adult psychiatric inpatients (126 male, 97 female) with a mean age of 42.3 years (± 2.2). Dental erosion detection was performed according to World Health Organization criteria. The medical evaluation included assessment of the body mass index (BMI). With appropriate sample weighting, relationships between erosive tooth wear, gastric reflux, and obesity were assessed using multivariable logistic regression.Ninety eight patients (43.9%) presented with erosive tooth wear. The mean BMI for the entire study population was 27.7 ± 6.3 kg/m2. Regression analysis showed a strong association between erosive tooth wear and chronic vomiting or bulimia (adjusted odds ratio = 2.11; 95% confidence interval [CI] = 1.98–5.07, P < .001), gastric reflux (adjusted odds ratio = 2.13; 95% CI = 1.34–6.23, P < .001), consumption of soft drinks (adjusted odds ratio = 2.14; 95% CI = 1.03–6.08, P < .001), and schizophrenia and delusional disorders (adjusted odds ratio = 2.07; 95% CI = 1.98–5.08, P < .001).This study demonstrates a significant association between erosive tooth wear prevalence and chronic vomiting or bulimia, consumption of soft drinks, and gastric reflux among resident patients at psychiatric hospital.

Bioactive remineralization of dentin surface with calcium phosphate-based agents: An in vitro analysis.

Background:With the increasing prevalence of erosive tooth wear affecting both adults and children; designing optimum protocols of management in a noninvasive manner is gaining precedence.Aim:Comparative evaluation of topically applied calcium phosphate-based agents casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and beta tricalcium phosphate (β-TCP) on the surface of eroded dentin.Materials and Methods:Dentin blocks from human third molars in four groups were subjected to the surface treatment: (G1) sound dentin (G2) demineralized dentin (G3) CPP-ACP (G4) β-TCP. All the samples except control (G1) were immersed in an acidic solution incubated at 37°C for 96 h. The samples in G3 and G4 were topically treated with CPP-ACP and β-TCP for 4 min twice daily for 14 days; followed by pH-cycling for 21 days. Surface hardness testing and surface morphology were observed using the scanning electron microscopy. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software with Kruskal-Wallis test and post hoc test.Results:Dentin treated with both CPP-ACP (37.25) and β-TCP (32.05) recorded significantly higher VHN than demineralized (G2-23.51) but lower compared to sound control (G1-57.06).Conclusion:The topical application of CPP-ACP and β-TCP agents shows definite potential in promoting the hardening of demineralized dentin surface.

Giomer technology for preventive and restorative clinical management of erosive tooth wear: a case report

Increasing prevalence of erosive tooth wear (ETW) is notable mainly due to current knowledge and its earlydiagnosis. Once teeth are functionally and/or esthetically affected, dental restorations may become necessary.Materials capable of interacting with the eroded dental tissue allied to their resistance to subsequent continuouserosive challenges are desirable. Giomer technology based on S-PRG (surface pre-reactive glass) filler has beenlaunching to provide benefits for the dental treatment due to its innovative multi-ionic release system, whichinvolves fluoride. This case report describes the employment of preventive and restorative materials basedon this technology for a patient under frequent erosive challenges and complaining about dental sensitivity.Patient reported immediate reduction on this sensitivity and the restorations has been followed up for 2 years,presenting satisfactory performance. S-PRG-based systems seem to be promissory for preventive and therapeuticmanagement of ETW used simultaneously with the patient compliance.KEYWORDSBiocompatible materials; Dental restoration; Smart polymer; Tooth erosion.

The Prevalence of Erosive Tooth Wear and Related Risk Factors in 6- to 12-Year-Old Students.

To evaluate the epidemiological characteristics of erosive tooth wear in primary school students aged 6-12 in Jinzhou, including: prevalence, severity, extent, intraoral distribution and associated risk factors. The data collection consists of two parts: the first part is the clinical examination of the participants. All erupted teeth were clinically assessed by three calibrated examiners, and classified according to the basic erosive wear examination (BEWE); The second part is a questionnaire about demographic information, parafunctional movement and lifestyle, completed by the parents or their guardians. A total of 1,469 children were included in this experiment; erosive tooth wear (ETW) prevalence (BEWE ≥ 1) was 54.9%. According to cumulative BEWE index, the proportion of different ETW severity (high, medium, low, none) was 6.8%, 16.3%, 27.0% and 49.9%, respectively. In an analysis of risk factors, family factor, age, gender, extracurricular study time, oral hygiene habit, bruxism, unilateral mastication and acid diet was associated with the prevalence of ETW. This study shows that ETW has a high prevalence in students aged 6-12, and more common in deciduous molars and deciduous canine. Abrasion, attrition and erosion play an important role in ETW.

The association between erosive tooth wear and diet, hygiene habits and health awareness in adolescents aged 15 in Poland

PurposeThe aim of the study was to assess the prevalence of erosive tooth wear (ETW) and risk indicators in the population of adolescents aged 15 in Poland.MethodsErosive tooth wear in 2639 participants was determined by calibrated examiners according to the BEWE scoring system, and the prevalence of risk factors was assessed on the basis of a survey.ResultsErosive tooth wear was reported in 24.3% of participants. Initial loss of surface (BEWE 1) was the predominant finding, observed in 21.3% of participants. Hard tissue loss (BEWE 2 and 3) occurred very rarely, only in 3% of participants. Acidic diet, masculine gender and lower socio-economic status were associated with higher prevalence and severity of erosive lesions in the examined population.ConclusionTwo modifiable factors—acidic diet and low health awareness—were found to be highly unsatisfactory in the adolescents aged 15 in Poland. Accordingly, to prevent the deterioration of the functionality and aesthetics of the teeth in young people, certain measures, such as routine clinical examination, education, dietary consulting and prophylaxis, should be implemented as early as possible, focusing predominantly on families with lower socio-economic status.

Erosion-inhibiting potential of a novel remineralising paste

The increasing prevalence of erosive tooth wear among children and young adults is an issue of growing concern, emphasising the need for improvement in the currently used preventive strategies. Our aim was to evaluate individual and synergistic effects of SnF2 and CPP-ACP pastes in inhibiting erosion at a nano-scale. Forty flat, polished enamel specimens were subjected to 10 erosion cycles, with each cycle comprising one-min erosion in citric acid (pH 3.0) and one-min exposure to human saliva. In each of the 3 experimental groups (n = 10 per group), a remineralising paste (10% CPP-ACP or 0.45% SnF2 (1,100 ppm F) or SnF2/CPP-ACP (combined 10% CPP-ACP and 0.45% SnF2)) was applied as a slurry in saliva between erosion cycles. No remineralising agent was used in control specimens (n = 10). Erosion was assessed by calculating erosion depth using a novel photolithographic technique combined with high-resolution 3D laser scanning microscopy from baseline to 1 min, 5 min and 10 min. A significant increase in erosion depth was detected in the control group as early as 1 min (69.4 nm) (P < 0.001), with the erosion depths being smaller for all three remineralising agents after 1 min (P ≤ 0.004). The overall trend of erosion depth reduction was SnF2/CPP-ACP > SnF2 > CPP-ACP > control. Application of SnF2-enriched CPP-ACP agent reduces dental erosion more than either SnF2 or CPP-ACP alone, offering a potentially more-effective preventive strategy to manage this condition.

Is Toothbrush Bristle Stiffness Associated with Erosive Tooth Wear in Adolescents? Findings from a Population-Based Cross-Sectional Study

This population-based cross-sectional study investigated the association between toothbrush bristle stiffness and the occurrence of erosive tooth wear (ETW) among 15- to 19-year-old adolescents from southern Brazil. Data collection included the application of questionnaires and clinical examination. One questionnaire on sociodemographic information (sex, age, and socioeconomic status) was sent to the parents/legal guardians, while the other was applied to students and collected data regarding oral hygiene habits (toothbrushing frequency, toothbrushing after meals, and toothbrush bristle stiffness) and dietary habits (frequency of consumption of soft drinks, citric fruits, and fruit juice). After tooth cleaning and drying, all erupted permanent teeth were clinically assessed and classified according to the Basic Erosive Wear Examination (BEWE) by 2 calibrated examiners. The association between explanatory variables and ETW prevalence was assessed using Poisson regression models. Prevalence ratios (PRs) and their 95% confidence intervals (CIs) were estimated. A total of 1,197 adolescents were included (participation rate 72.3%). The overall prevalence of ETW was 57%. The final model showed that individuals who used toothbrushes with soft (PR = 1.28, 95% CI = 1.02–1.60) or medium (PR = 1.30, 95% CI = 1.01–1.69) bristles presented a higher ETW prevalence than those who used toothbrushes with extra-soft bristles, even after the adjustment for important cofactors. In conclusion, this study found a very weak but significant association between toothbrush bristle stiffness and ETW among Brazilian adolescents. Considering the cross-sectional design of this study and considering that some association was found even in such a young population, future studies using different designs and including different age-groups might elucidate the clinical relevance of this finding.

Different Risk Factors for Erosive Tooth Wear in Rural and Urban Nepal: A National Study.

Background: Erosive tooth wear (ETW) is of growing concern, but data on ETW among Nepalese children are scarce. The main aim of the study was to investigate the prevalence and severity of ETW among Nepalese schoolchildren. We also aimed to analyse the risk indicators for ETW according to location (rural/urban) and the role of obesity in the risk for ETW. Methods: This national study was conducted among 5–15-year-old Nepalese schoolchildren from different regions. Altogether, 1137 out of 1151 schoolchildren participated in both a clinical examination and a survey. ETW was recorded using the Basic Erosive Wear Examination. Results: The prevalence of ETW was 65%. One-fifth of the examined subjects were in need of preventive or restorative treatment. Living in an urban area and studying in a private school were protective factors for ETW, whereas consuming fruits frequently and using charcoal for tooth cleaning increased the odds for ETW. Central obesity was the strongest risk indicator for ETW among urban residents. Conclusions: ETW of low severity is common among Nepalese children and adolescents. Socio-demographic factors influence the prevalence of ETW in Nepal and there seems to be different factors that play a role in the ETW process according to location of residence.

Erosive Potential of Bottled Salad Dressings.

A previous clinical study showed that the prevalence of erosive toothwear in vegetarians is statistically significantly higher than in nonvegetarians, due to the consumption of vinegar and other acidic foodstuffs. To adequately inform patients, this study investigated the erosive potential of bottled salad dressings available in Switzerland and compared it with that of orange juice. Materials and Methods: One hundred enamel samples of bovine teeth were divided into ten groups. Samples were placed in 1 of 9 bottled salad dressings or orange juice (Granini) for 2 min. Afterwards, they were rinsed with Zürich tap water for 30 s, followed by abrasion with a toothbrush for 20 brush strokes and a toothpaste-saliva mixture. Erosive/abrasive enamel wear was determined with contact profilometry after 40 cycles. Results: The enamel wear (median/IQR) caused by Tradition Sauce Balsamique (9.5 µm/5.3 µm), M-Classic Dressing Italiano (10.9 µm/12.3 µm), Betty Bossi Balsamico Dressing (9.4 µm/4.5 µm) and Thomy Balsamico Vinaigrette Dressing (14.2 µm/6.5 µm) was statistically significantly higher than that caused by orange juice (2.4 µm/0.8 µm). Enamel wear caused by M-Classic Dressing French Joghurt (0.2 µm/0.2 µm) and Coop Qualité & Prix French Dressing (1.2 µm/1.0 µm) was statistically significantly lower compared to that of orange juice. Conclusions: The pure balsamico vinegar-based dressings (Italian type) showed a statistically significantly higher erosive potential than orange juice, whereas dressings containing calcium-rich products (enriched with milk and/or cream) (French-type) caused lower enamel wear than orange juice. The study shows that some bottled dressings have erosive potential even higher than orange juice and patients should be informed accordingly.

Consumption of Acidic Beverages is a Predisposing Factor for Erosive Tooth Wear in Preschool Children: A Population-based Study.

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

Erosive Tooth Wear, Presence of Parafunctional Habits and Tooth Injuries-Occurrence in a Group of Children and Adolescents Exposed to Domestic Violence.

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

Erosive Tooth Wear among Adults in Lithuania: A Cross-Sectional National Oral Health Study

Introduction: Erosive tooth wear has a multifactorial origin, where multiple risks contribute to its initiation and subsequent progression. The prevalence of tooth wear varies among countries; therefore, national studies are needed to examine the prevalence of this condition and its associated determinants. Materials and Methods: A sample of this national study included a total of 1,397 adults (response rate of 52%). Severity and number of teeth with erosive tooth wear, caries experience (D₃MFS), and fluorosis were assessed clinically. A self-reported questionnaire inquired about sociodemographics, oral health behavior, diet, and general health. Fluoride levels in drinking water at the recruitment areas were also recorded. Data were analyzed by bivariate and multivariate methods. Results: The prevalence of erosive tooth wear in enamel and dentin combined was 59% among 35- to 44-year-old, 75% among 45- to 54-year-old, 70% among 55- to 64-year-old, and 66% among 65- to 74-year-old males. The prevalence among females in the respective age groups was 44, 60, 63, and 59%. Erosive tooth wear in enamel was associated with a lower fluoride level (≤1 ppm) in the drinking water (OR 2.1, 95% CI 1.1–4.2). Erosive tooth wear in dentin was positively associated with male gender (OR 1.7, 95% CI 1.1–2.5), periurban/rural residency (OR 1.6, 95% CI 1.1–2.4), older age (OR 1.6, 95% CI 1.3–1.9), presence of reflux (OR 3.3, 95% CI 1.0–10.9), and negatively with higher D₃MFS scores (OR 0.7, 95% CI 0.5–0.9). Conclusions: The prevalence of erosive tooth wear in enamel and dentin was relatively high in Lithuania; the erosive tooth wear in enamel and dentin combined was 52% among 35- to 44-year-olds, 68% among 45- to 54-year-olds, 67% among 55- to 64-year-olds, and 63% among 65- to 74-year-olds. Lower fluoride level in drinking water was associated with erosive tooth wear in enamel. Male gender, residency in periurban/rural areas, older age, and presence of acid reflux were associated with higher odds, while higher D₃MFS scores were associated with lower odds for erosive tooth wear in dentin. These results can be used to plan dental public health prevention.

Associations between obesity, dental caries, erosive tooth wear and periodontal disease in adolescents: a case-control study.

To compare oral health [dental caries, periodontal status, and erosive tooth wear (ETW)], diet and oral hygiene habits between obese and normal weight adolescents, and to explore possible risk associations. In this case-control study, a convenience sample of 71 obese adolescents (age range 11-18) from a rehabilitation centre, and 54 age-sex-matched normal weight adolescents were selected for this study. Groups were defined using the Body Mass Index and growth curves for Flemish adolescents. Oral health was measured using DMFT, gingival, plaque and BEWE index. A validated questionnaire was utilized to assess diet and oral hygiene habits. Mann-Whitney U test was used to compare oral health between groups. Multivariate Firth's logistic regression analysis, conditional regression analysis and classification trees were used to detect associations between oral health and potential risk factors. Prevalence of ETW did not differ significantly between groups, although obese adolescents presented a significantly higher caries experience, gingivitis, presence of plaque and periodontal problems, compared to normal weight adolescents. After adjusting for age and sex, obesity was associated only with the presence of dental plaque (p ≤ 0.001). Obese participants reported a significantly higher intake of sugar-rich and caloric food items than normal weight group. The consumption of acidic drinks, however, was similar. Obese adolescents presented significantly higher caries experience, gingivitis and plaque, although after adjusting, obesity became significantly associated only with the presence of dental plaque.
