Comparison of clinical performance of obturating materials in pulpectomies: A randomized clinical trial

BACKGROUND

Chemomechanical debridement is insufficient to disinfect all bacteria from the root canals of primary teeth, and obturation of canals with an appropriate material thus acquires excellent importance and remains a critical step in the ultimate success of pulpectomy.

AIM

The aim of the study was to compare and evaluate Endoflas, Metapex, and a mixture of calcium hydroxide (CH) and zinc oxide (ZnO) as obturating materials (OMs) in primary mandibular second molars.

MATERIALS AND METHODS

Seventy-five mandibular second primary molars requiring pulpectomies were identified in children aged 4-8 years. They were randomly allocated to the three treatment groups according to the type of OM received using the block randomization technique. After the completion of chemomechanical debridement, the canals were filled with Endoflas, Metapex, and CH-ZnO mixture, respectively. The intergroup clinical and radiographic comparison was made based on Coll and Sadrian criteria to decipher their clinical performance at 1, 3, and 6 months.

RESULTS

No statistically significant differences between the groups were observed at any evaluation time interval (P > 0.05). At 6 months, the clinical success rates were 95.2% in Endoflas, 96% in Metapex, and 95.8% in the CH and ZnO mixture groups, respectively. The materials, however, behaved differently in different clinical situations.

CONCLUSION

Based on the observations, all three OMs showed similar clinical success in maintaining tooth functioning, but their use can be restricted to indications. However, prospective studies with longer follow-ups with more stringent eligibility criteria are required to reach more definitive conclusions.

Spatial and Seasonal Drinking Water Quality Assessment in a Sub-Saharan Country (Guinea-Bissau)

The United Nations Sustainable Development Goal target 6.1 calls for universal and equitable access to safe and affordable drinking water. Worldwide, about 2.2 billion people live without access to safe water, and millions of people suffer from waterborne pathogens each year, representing the most pressing situation in developing countries. The aim of this study was to investigate the drinking water quality dynamics across an endemic cholera sub-Saharan country (Guinea-Bissau), and understand its implications for public health. Microbiological and physical–chemical quality parameters of 252 major water sources spread all over the country were seasonally surveyed. These comprised hand-dug shallow wells and boreholes, fitted with a bucket or a pump to retrieve water. The results showed that the majority of water sources available to the population were grossly polluted with faecal material (80%), being unsuitable for consumption, with significantly (p < 0.05) higher levels during the wet season. Hand-dug wells revealed the highest contamination levels. The chemical contamination was less relevant, although 83% of the water sources were acidic (pH < 6.5). This study highlights the potential health risk associated with the lack of potable drinking water, reinforcing the evidence for water monitoring, and the need to improve WASH (water, sanitation, and hygiene) infrastructure and water management in West African countries. In addition, the authors suggest easy-to-implement interventions that can have a dramatic impact in the water quality, assisting to reduce the associated waterborne diseases rise.

A systematic review of dietary acids and habits on dental erosion in adolescents

BACKGROUND

Dental erosion is the dissolution of dental hard tissues caused by acids of a non-bacterial origin. Dietary acids are considered the predominant and most controllable factor.

AIM

To synthesise the literature on the effects of dietary acids and habits on dental erosion in the permanent dentition of 10- to 19-year-old adolescents.

MATERIALS AND METHODS

An electronic literature search was undertaken in Cochrane, MEDLINE, CINAHL, Dentistry & Oral Sciences Source via EBSCOhost, and Embase with no restriction on the date of publication.

RESULTS

The initial search identified 449 articles, and 338 remained after removal of duplicates. Seventy-seven articles remained after screening of titles and abstracts, and 52 were eligible for the full-text review. A considerable variety of beverages, food, and dietary habits were reported as risk factors for dental erosion. The most consistent findings implicated the erosive potential of carbonated beverages and the consumption of acidic drinks at bedtime.

CONCLUSIONS

Although results were not consistent between cohort and cross-sectional studies, this review suggests certain dietary risk factors may contribute to dental erosion in adolescents. There is a need for more high-quality cohort studies to establish more conclusive evidence on the role of dietary acids and habits on dental erosion.

Quality Assessment of Three Types of Drinking Water Sources in Guinea-Bissau

The lack of access to safe drinking water causes important health problems, mainly in developing countries. In the West African country Guinea-Bissau, waterborne diseases are recognised by WHO as major infectious diseases. This study analysed the microbiological and physicochemical parameters of drinking water in the capital Bissau and its surroundings. Twenty-two sites belonging to different water sources (piped water, tubewells and shallow wells) were surveyed twice a day for three weeks, in both dry and wet seasons. Most of the microbiological parameters were out of the acceptable ranges in all types of water and both seasons and tended to worsen in the wet season. Moreover, in Bissau, the levels of faecal contamination in piped water increased from the holes to the consumer (tap/fountain). Several physicochemical variables showed values out of the internationally accepted ranges. Both well sources showed low-pH water (4.87–5.59), with high nitrite and iron levels in the wet season and high hexavalent chromium concentration in the dry season. The residual chlorine never reached the minimum recommended level in any of the water sources or seasons, suggesting a high risk of contamination. Results reveal a lack of quality in the three water sources analysed, coherent with the high number of diarrheal cases in the country. There is an urgent need to improve sanitarian conditions to reduce the disease burden caused by these waterborne illnesses.

The effect of various asthma medications on surface roughness of pediatric dental restorative materials: An atomic force microscopy and scanning electron microscopy study

The aim of the study is to examine and compare the effects of various inhaled asthma medications (IAMs) on the surface roughness of dental restorative materials (DRMs). In total, 192 samples were prepared including 32 samples for the each material group from six different DRMs [Nanohybrid composite (Filtek Z550), Nanofilled flowable composite (Filtek Ultimate), Compomer (Dyract XP), Conventional glass ionomer (Fuji IX Fast), Resin-modified glass ionomer (Fuji II LC), Self-adhering flowable composite (Fusio Liquid Dentin)]. Each group, were divided into four subgroups (n = 8) according to four different IAMs. Surface roughness values (Ra) were obtained by atomic force microscopy (AFM). After the initial roughness of DRMs was analyzed by using AFM and scanning electron microscopy (SEM), each samples were exposed to the same IAMs for 21 days and all analysis were repeated on the 7th and 21st day. Ras increased in all DRMs and higher Ras were recorded through the long-term IAMs administrations. For all IAMs, Fuji II LC had the highest Ra and Filtek Z550 had the lowest Ra. The combined IAM created the highest roughness change on the 7th and 21st day compared to other IAMs. As a result, in in vitro conditions IAMs significantly increased the surface roughness of DRMs.

Conservative Management of Dental Erosion in Adolescents with Medical Conditions

The prevalence of dental erosion among children and adolescents is trending higher in recent decades and is becoming a major concern. Dental erosion can be caused by either extrinsic or intrinsic acids or both. One of the established aetiological factors for dental erosion by intrinsic acid is the gastrooesophageal reflux disease. The degree of dental erosions may be influenced by any medical conditions that cause a reduction in salivary flow such as the salivary gland excision, autoimmune disease, radiation to the head and neck regions, and medications. If left untreated, the dental erosion can cause dentine hypersensitivity, loss of occlusal vertical height, and aesthetic problems. For effective management of dental erosion, the aetiology of each case must be determined, and its detection at an early stage is of prime importance. This case report illustrates the conservative management of dental erosion in two adolescent patients presented with their medical conditions and behaviour issues. The aim of the treatments was to preserve the vitality of the affected teeth. The treatments were successfully completed using a conservative approach, with the patients' medical conditions taken into consideration.

Dentin Erosion: Method Validation and Efficacy of Fluoride Protection

The aging population experiences more gingival recession and root exposure which increases the opportunity for dentin erosion. This study tested the use of transverse microradiography (TMR) methods to assess dentin erosion and the interaction between fluoride and citric acid on the amount of erosion in the dentin samples. In a 4 × 3 interaction experimental design, four fluoride concentrations (0.00, 25.0, 50.0, and 100.0 mg/L) and three citric acid concentrations (0.0, 0.25, and 1.00%) were combined to form 12 experimental solutions. Forty-eight dentin samples were placed in the experimental solutions for 1 and 4 h and the amount of surface lost was determined by TMR methods. The resolution of the TMR method was 0.9 μm per pixel with a 0.1% and a 5% confidence interval of ±4.2 μm. Dentin erosion increased with the concentration of citric acid and time, the erosion decreased when concentration of fluoride was increased. Effects due to fluoride and citric acid concentrations individually, and their interaction on the amount of erosion observed was statistically significant (p < 0.0001). This study found that TMR methods are appropriate and that 25.0 mg/L was the optimal fluoride concentration to protect dentin from a 1.00% citric acid challenge.

Establishing the Effect of Brushing and a Day's Diet on Tooth Tissue Loss in Vitro

To develop an in vitro model to mimic the effects of meals equivalent to a day’s diet on tooth tissue loss (TTL). To identify how diet effects tooth wear and to test the efficacy of dental products designed to reduce tooth wear in a more realistic environment. A typical Friday diet was devised comprising: Breakfast then brushing, lunch, dinner then brushing. Groups of enamel samples were exposed to one meal, or all three in series, a control group was exposed to water and brushed. The daily cycle was repeated to represent two days’ consumption; TTL was quantified by non-contact profilometry. This pilot study highlighted adaptions that could be made to the model such as human enamel and saliva to further replicate natural eating habits. The sum of the TTL measured after Breakfast, lunch and dinner (bovine enamel specimens exposed to single meals) was less than that exhibited by the group of samples exposed to the series of meals but this difference was not significant (p = 0.09).In the absence and presence of brushing, TTL caused by breakfast and dinner was similar, but significantly greater than that caused by lunch (p < 0.05). While brushing increased TTL, this increase was not significant. It is possible to model a daily diet in vitro, and the data obtained confirms that the combination of food and drink affects the degree of TTL. This supports the further development of an in vitro model that includes alternative foodstuffs. This would aid understanding of the effects different diets have on TTL and could test new products designed to prevent TTL.

The evidence base for professional and self-care prevention--caries, erosion and sensitivity

Background

The aim of this conference paper was to examine the evidence base for primary and secondary prevention of dental caries, erosions and dentin hypersensitivity through professional and self-care measures.

Methods

A mapping of systematic reviews (SR) of literature was carried out in PubMed and the Cochrane library through April 2014 using established MeSH-terms and disease-related search words in various combinations. The search was restricted to SR's published in English or Scandinavian and all age groups were considered. The reference lists of the selected papers were hand-searched for additional review articles of potential interest. Meta-analyses, guidelines and treatment recommendations were considered only when SR's were lacking. In the event of updates or multiple systematic reviews covering the same topic, only the most recent article was included. No quality assessment of the systematic reviews was carried out. The quality of evidence was rated in four levels according to the GRADE scale.

Results

In total, 39 SR were included. For primary caries prevention, the quality of evidence was high for the use of fluoride toothpaste (with and without triclosan) and moderate for fluoride varnish and fissure sealants. The quality of evidence for fluoride gel, fluoride mouth rinse, xylitol gums and silver diamine fluoride (SDF) was rated as low. For secondary caries prevention and caries arrest, only fluoride interventions and SDF proved consistent benefits, although the quality of evidence was low. Likewise, the GRADE score for preventing erosions located in the enamel with fluoride supplements was low. The quality of evidence for various professional and self-care methods to prevent and manage dentine hypersensitivity was very low.

Conclusions

There are knowledge gaps in many domains of cariology and preventive dentistry that must be addressed and bridged through clinical research of good quality.

Factors affecting the dental erosion severity of patients with eating disorders

BACKGROUND

Intraoral disease is a common occurrence in patients with eating disorders, particularly dental erosion, which frequently becomes severe and may hinder daily life. The severity varies from patient to patient. Understanding the underlying mechanisms may help prevent dental erosion in these patients. Accordingly, we investigated the relationship between the severity of erosion and the behavior of patients with eating disorders, with a focus on daily diet and vomiting behavior.

METHODS

A total 71 female eating disorder outpatients from the Clinical Center of Psychosomatic Dentistry of Nippon Dental University Hospital and the Psychosomatic Internal Medicine Department of Kudanzaka Hospital or who were hospitalized at Hasegawa Hospital were enrolled. Dental erosion severity and location were determined by oral examination. Patients who induced vomiting were queried on their behavior during vomiting and on routine diet habits. Patients with dental erosion were further divided into mild and severe groups based on the lesion severity and the groups compared.

RESULTS

Dental erosion was observed in 43 of 50 subjects who induced vomiting. Dental erosion was most frequent on the palatal side of the anterior maxillary teeth, occurring in 81.3% of the subjects. There were significant differences observed between the mild and severe groups according to post-vomiting oral hygiene. Significantly more subjects in the mild group consumed large amounts of water before vomiting, and significantly more subjects in the severe group routinely consumed carbonated beverages or sweetened food.

CONCLUSIONS

While self-induced vomiting is the main cause of dental erosion in eating disorder patients, the erosion severity may be affected by behavior when inducing vomiting or by routine consumption of certain foods and beverages. Addressing these factors may help prevent severe dental erosion in patients who chronically induce vomiting.

Tooth erosion and eating disorders: a systematic review and meta-analysis

Background

Eating disorders are associated with the highest rates of morbidity and mortality of any mental disorders among adolescents. The failure to recognize their early signs can compromise a patient's recovery and long-term prognosis. Tooth erosion has been reported as an oral manifestation that might help in the early detection of eating disorders.

Objectives

The aim of this systematic review and meta-analysis was to search for scientific evidence regarding the following clinical question: Do eating disorders increase the risk of tooth erosion?

Methods

An electronic search addressing eating disorders and tooth erosion was conducted in eight databases. Two independent reviewers selected studies, abstracted information and assessed its quality. Data were abstracted for meta-analysis comparing tooth erosion in control patients (without eating disorders) vs. patients with eating disorders; and patients with eating disorder risk behavior vs. patients without such risk behavior. Combined odds ratios (ORs) and a 95% confidence interval (CI) were obtained.

Results

Twenty-three papers were included in the qualitative synthesis and assessed by a modified version of the Newcastle-Ottawa Scale. Fourteen papers were included in the meta-analysis. Patients with eating disorders had more risk of tooth erosion (OR = 12.4, 95%CI = 4.1–37.5). Patients with eating disorders who self-induced vomiting had more risk of tooth erosion than those patients who did not self-induce vomiting (OR = 19.6, 95%CI = 5.6–68.8). Patients with risk behavior of eating disorder had more risk of tooth erosion than patients without such risk behavior (Summary OR = 11.6, 95%CI = 3.2–41.7).

Conclusion

The scientific evidence suggests a causal relationship between tooth erosion and eating disorders and purging practices. Nevertheless, there is a lack of scientific evidence to fulfill the basic criteria of causation between the risk behavior for eating disorders and tooth erosion.

Prevalence of antibiotic resistance in bacteria isolated from drinking well water available in Guinea-Bissau (West Africa)

The dissemination of antibiotic-resistant bacteria and the spread of antibiotic resistance genes are a major public health concern worldwide, being even proposed as emerging contaminants. The aquatic environment is a recognized reservoir of antibiotic resistant bacteria, and antibiotic resistance genes have been recently detected in drinking water. In this study, the water quality and the prevalence of antibiotic resistance of heterotrophic culturable bacteria were characterized seasonally in wells that serve the population of Guinea-Bissau (West Africa) as the sole source of water for drinking and other domestic proposes. The results revealed that well water was unfit for human consumption independently of the season, owing to high acidity and heavy fecal contamination. Moreover, potentially pathogenic bacteria, which showed resistance to the most prescribed antibiotics in Guinea-Bissau, were isolated from well water, posing an additional health risk. Our results suggest that well water not only fosters the transmission of potential pathogenic bacteria, but also represents an important reservoir for the proliferation of antibiotic resistant bacteria, that can aggravate the potential to cause disease in a very vulnerable population that has no other alternative but to consume such water.

Analysis of the bacterial community composition in acidic well water used for drinking in Guinea-Bissau, West Africa

Potable water is a resource out of reach for millions worldwide, and the available water may be chemically and microbiologically compromised. This is particularly acute in Africa, where water-networks may be non-existent or restricted to a small fraction of the urban population, as in the case of Guinea-Bissau, West Africa. This study was carried out seasonally in Bolama (11°N), where unprotected hand-dug wells with acidic water are the sole source of water for the population. We inspected the free-living bacterial community dynamics by automated rRNA intergenic spacer analyses, quantitative polymerase chain reaction and cloning approaches. The results revealed a clear seasonal shift in bacterial assemblage composition and microbial abundance within the same sampling site. Temperature, pH and turbidity, together with the infiltration and percolation of surface water, which takes place in the wet season, seemed to be the driving factors in the shaping and selection of the bacterial community and deterioration of water quality. Analysis of 16S rDNA sequences revealed several potential pathogenic bacteria and uncultured bacteria associated with water and sediments, corroborating the importance of a culture-independent approach in drinking water monitoring.

Risk indicators associated with dental erosion among Jordanian school children aged 12-14 years of age

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.

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.

Carbohydrate supplementation and prolonged intermittent high-intensity exercise in adolescents: research findings, ethical issues and suggestions for the future

In the last decade, research has begun to investigate the efficacy of carbohydrate supplementation for improving aspects of physical capacity and skill performance during sport-specific exercise in adolescent team games players. This research remains in its infancy, and further study would be beneficial considering the large youth population actively involved in team games. Literature on the influence of carbohydrate supplementation on skill performance is scarce, limited to shooting accuracy in adolescent basketball players and conflicting in its findings. Between-study differences in the exercise protocol, volume of fluid and carbohydrate consumed, use of prior fatiguing exercise and timing of skill tests may contribute to the different findings. Conversely, initial data supports carbohydrate supplementation in solution and gel form for improving intermittent endurance running capacity following soccer-specific shuttle running. These studies produced reliable data, but were subject to limitations including lack of quantification of the metabolic response of participants, limited generalization of data due to narrow participant age and maturation ranges, use of males and females within the same sample and non-standardized pre-exercise nutritional status between participants. There is a lack of consensus regarding the influence of frequently consuming carbohydrate-containing products on tooth enamel erosion and the development of obesity or being overweight in adolescent athletes and non-athletes. These discrepancies mean that the initiation or exacerbation of health issues due to frequent consumption of carbohydrate-containing products by adolescents cannot be conclusively refuted. Coupled with the knowledge that consuming a natural, high-carbohydrate diet -3-8 hours before exercise can significantly alter substrate use and improve exercise performance in adults, a moral and ethical concern is raised regarding the direction of future research in order to further knowledge while safeguarding the health and well-being of young participants. It could be deemed unethical to continue study into carbohydrate supplementation while ignoring the potential health concerns and the possibility of generating similar performance enhancements using natural dietary interventions. Therefore, future work should investigate the influence of pre-exercise dietary intake on the prolonged intermittent, high-intensity exercise performance of adolescents. This would enable quantification of whether pre-exercise nutrition can modulate exercise performance and, if so, the optimum dietary composition to achieve this. Research could then combine this knowledge with ingestion of carbohydrate-containing products during exercise to facilitate ethical and healthy nutritional guidelines for enhancing the exercise performance of adolescents. This article addresses the available evidence regarding carbohydrate supplementation and prolonged intermittent, high-intensity exercise in adolescent team games players. It discusses the potential health concerns associated with the frequent use of carbohydrate-containing products by adolescents and how this affects the research ethics of the field, and considers directions for future work.

A composite approach to the management of worn maxillary first molar teeth

A lady with extrinsic acid erosion was referred to the restorative department at Bristol Dental Hospital by her General Dental Practitioner (GDP) for restoration of worn maxillary first molar teeth. These teeth were both causing symptoms of dentinal sensitivity and two attempts had been made to restore them with composite by her GDP. The restorations failed because there was insufficient space to bond the composite in place, which was due to dento-alveolar compensation of the first molars into the space created by the wear. Following relevant preventive advice, the maxillary first molar teeth were restored with 'high' direct composite resin, which allowed for adequate strength in bulk for retention while acting as fixed intrusion devices. These cured the patient's sensitivity and within four months her occlusion compensated for the composites and had re-established.

Erosion and abrasion on dental structures undergoing at-home bleaching

This review investigates erosion and abrasion in dental structures undergoing at- home bleaching. Dental erosion is a multifactorial condition that may be idiopathic or caused by a known acid source. Some bleaching agents have a pH lower than the critical level, which can cause changes in the enamel mineral content. Investigations have shown that at-home tooth bleaching with low concentrations of hydrogen or carbamide peroxide have no significant damaging effects on enamel and dentin surface properties. Most studies where erosion was observed were in vitro. Even though the treatment may cause side effects like sensitivity and gingival irritation, these usually disappear at the end of treatment. Considering the literature reviewed, we conclude that tooth bleaching agents based on hydrogen or carbamide peroxide have no clinically significant influence on enamel/dentin mineral loss caused by erosion or abrasion. Furthermore, the treatment is tolerable and safe, and any adverse effects can be easily reversed and controlled.

A literature review of dental erosion in children

Dental erosion is increasingly recognized as a common condition in paediatric dentistry with complications of tooth sensitivity, altered aesthetics and loss of occlusal vertical dimension. The prevalence of erosion in children has been reported to range from 10% to over 80%. The primary dentition is thought to be more susceptible to erosion compared to the permanent dentition due to the thinner and less mineralized enamel. The aim of this paper was to critically review dental erosion in children with regards to its prevalence, aetiology, diagnosis and prevention. The associations between erosion and other common conditions in children such as caries and enamel hypoplasia are also discussed.

A controlled study of dental erosion in 2- to 4-year-old twins

BACKGROUND

Dental erosion (DE) in children is a significant oral health issue and has become a focus for research in clinical paediatric dentistry.

AIM

This study investigated DE in the primary dentition of 2- to 4-year-old twin and singleton children with regard to the genetic, medical and dietary factors associated with the condition.

DESIGN

The 128 subjects consisted of 88 twin children (31 monozygous, 50 dizygous, 7 unknown zygosity) and singletons (n = 40) aged 2-4 years. Medical, dental, and dietary histories were obtained. The children were examined for DE using a modified index.

RESULTS

The prevalence of DE by subject affected was 77% in monozygotic twins (MZ), 74% in dizygotic twins (DZ), and 75% in singleton controls (P > 0.1). Of the teeth scored, 12% had mild, 10% moderate, and 1% severe lesions, and DE was more severe in the older age group (P < 0.05). Concordance rates for erosion lesions in MZ and DZ co-twins were not statistically significant.

CONCLUSIONS

The prevalence of DE and the concordance of erosion lesions were similar between MZ and DZ twins and singleton children, suggesting that the contribution of genetic factors to DE is negligible.

Soft drink, software and softening of teeth - a case report of tooth wear in the mixed dentition due to a combination of dental erosion and attrition

This case report describes a 9-year-old boy with severe tooth wear as a result of drinking a single glass of soft drink per day. This soft drink was consumed over a period of one to two hours, while he was gaming intensively on his computer. As a result, a deep bite, enamel cupping, sensitivity of primary teeth and loss of fillings occurred. Therefore, dentists should be aware that in patients who are gaming intensively, the erosive potential of soft drinks can be potentiated by mechanical forces leading to excessive tooth wear.
