Gastroesophageal reflux is not associated with dental erosion in children

Risk factors of tooth wear in permanent dentition: A scoping review

BACKGROUND

Tooth wear (TW) prevalence is high and increasing and has important consequences on the patient's quality of life. Knowledge of risk factors is crucial to promote diagnosis, prevention strategies and timely interceptive treatment. Many studies have identified TW risk factors.

OBJECTIVE

This scoping review aims to map and describe suspected available factors associated with TW in permanent dentition based on quantitative measurement.

METHODS

The scoping review was conducted using the PRISMA extension of the Scoping Reviews checklist. The search was conducted in October 2022 from the Medline® (PubMed® interface) and Scopus® databases. Two independent reviewers selected and characterised the studies.

RESULTS

2702 articles were identified for assessment of titles and abstracts, and 273 articles were included in the review. The results show a need to standardise TW measurement indices and the study design. The included studies highlighted various factors, classified into nine domains: sociodemographic factors, medical history, drinking habits, eating habits, oral hygiene habits, dental factors, bruxism and temporomandibular disorders, behavioural factors, and stress. Results related to chemical TW (erosion) risk factors underline the importance of eating disorders, gastroesophageal reflux and lifestyle, particularly drinking and eating behaviours, which supports developing public health information campaigns and interventions. Besides chemical, this review identifies evidence of several mechanical TW risk factors, such as toothbrushing and bruxism; the influence of this last factor needs to be further explored.

CONCLUSIONS

TW management and prevention require a multidisciplinary approach. Dentists are in the first line to detect associated diseases such as reflux or eating disorders. Consequently, practitioners' information and guideline diffusion should be promoted, and a TW risk factors checklist (the ToWeR checklist) is proposed to help diagnostic approaches.

Prevalence and association of gastroesophageal reflux and dental erosion: An overview of reviews

OBJECTIVES

The aim of this overview of reviews was to retrieve and evaluate the available evidence concerning the prevalence and association between gastroesophageal reflux disease (GERD) and erosive tooth wear (ETW).

DATA

A literature search was conducted in electronic databases and relative systematic reviews with or without meta-analyses were located. Updated supplemental search was also undertaken to identify additional primary studies.

SOURCES

Medline (via Pubmed), Embase, Scopus, Cochrane Register of Systematic Reviews, PROSPERO and Epistemonikos.org database were searched. Additional search of the grey literature, abstracts of conferences and meetings as well as manual search of the reference lists of retrieved studies, was also performed.

STUDY SELECTION

The search retrieved 116 systematic reviews of which 10 were considered eligible and eight additional primary studies.

CONCLUSIONS

GERD constitutes a risk factor for ETW and there is a positive association between the two conditions. In the present overview, despite the heterogeneity between studies and the low level of evidence, it was clearly supported that individuals with GERD have an increased probability of also presenting with signs of ETW. In special groups of population, a high association was found between GERD and ETW. The geographic location may affect the association between GERD and ETW, while regarding the effect of flow rate, buffering capacity of saliva and oral microbial changes caused by GERD, the results were controversial.

CLINICAL SIGNIFICANCE

Appropriate preventive dental care should be considered for individuals with GERD and a multidisciplinary medical and dental approach for the management of individuals with ETW is advised. The results of this study can be used by dentists dealing with typical and atypical GERD signs and symptoms in the oral environment, but also by the physicians and gastroenterologists who need to motivate their patients for oral examination.

Assessment of demineralized tooth lesions using optical coherence tomography and other state-of-the-art technologies: a review

Tooth demineralization is one of the most common intraoral diseases, encompassing (1) caries caused by acid-producing bacteria and (2) erosion induced by acid of non-bacterial origin from intrinsic sources (e.g. stomach acid reflux) and extrinsic sources (e.g. carbonated drinks). Current clinical assessment based on visual-tactile examination and standardized scoring systems is insufficient for early detection. A combination of clinical examination and technology is therefore increasingly adapted. This paper reviews various procedures and technologies that have been invented to diagnose and assess the severity of tooth demineralization, with focus on optical coherence tomography (OCT). As a micron-resolution non-invasive 3D imaging modality, variants of OCT are now available, offering many advantages under different working principles for detailed analytical assessment of tooth demineralization. The roles, capabilities and impact of OCT against other state-of-the-art technologies in both clinical and research settings are described. (139 words).

Reflux and dental disorders in the pediatric population: A systematic review

OBJECTIVES

To investigate the role of laryngopharyngeal reflux (LPR) or gastroesophageal reflux disease (GERD) in the development of dental disorders in pediatric population.

METHODS

PubMed, Scopus Cochrane database were assessed for subject headings using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) recommendations. Relevant studies published between January 1990 and January 2020 describing the association between reflux and dental disorders in children were retrieved. Three authors reviewed the LPR diagnosis method; inclusion criteria and outcomes. The bias analysis was performed through the tools of the Oxford Centre for Evidence-Based Medicine evidence levels.

RESULTS

The electronic search identified 126 publications, of which 11 clinical studies and 2 basic science researches met our inclusion criteria. There is an important heterogeneity between studies about diagnostic method and clinical outcome evaluation. All studies based the reflux diagnosis on GERD criteria. No author considered hypopharyngeal nonacid reflux episodes through hypopharyngeal-esophageal intraluminal multichannel impedance pH monitoring (HEMII-pH). The results of studies support a higher prevalence of dental erosion in children with GERD compared with healthy individuals. Controversial findings were found about the potential association between reflux and caries, and the modification of both saliva composition and production in reflux children.

CONCLUSION

The association between reflux and dental disorder is still uncertain. Future studies considering pharyngeal acid and nonacid reflux episodes through HEMII-pH are needed to confirm this hypothesis. The pepsin detection in saliva would be an additional way for detecting LPR in children with dental disorders.

Association between soft drink consumption, gastric reflux, dental erosion, and obesity among special care children

OBJECTIVES

This study assessed the association between soft drink consumption, gastric reflux, dental erosion, and obesity among special care children.

MATERIALS AND METHODS

A total of 350 special care children (male-131, female-219) mean age of 12.6 (± 2.6) years were included. Detection of dental erosion was performed according to the World Health Organization criteria. The medical evaluation assessed body mass index (BMI). With appropriate sample weighting, relationships between dental erosion prevalence and obesity were assessed using multivariable logistic regression.

RESULTS

Overall prevalence of dental erosion was 36%. Mean BMI for entire study population was 24.7 (± 7.8). Regression analysis showed strong association between dental erosion prevalence and consumption of soft drinks (adjusted odds ratio = 1.8; 95% CI = 0.71-2.92, P < .05), bulimia (adjusted odds ratio = 2.27; 95% CI = 0.99-4.28, P < .001), and gastric reflux (adjusted odds ratio = 2.24; 95% CI = 0.82-4.1, P < .001). Bivariate analysis showed high prevalence of dental erosion among obese children compared to children with normal weight (P = .04).

CONCLUSION

The present study demonstrated a significant association between dental erosion prevalence and consumption of soft drinks and gastric reflux among special care children.

Associations among Bruxism, Gastroesophageal Reflux Disease, and Tooth Wear

The relationship between bruxism and tooth wear is contentious in the literature. The pathophysiological processes of tooth wear may be complicated by the relationship between bruxism and gastroesophageal reflux disease (GERD). The objective of this study was to evaluate the associations among bruxism, GERD, and tooth wear. Two complementary studies were performed: a case-control study to verify the linkage between GERD and bruxism and a cross-sectional study on the same cohort to establish the connection between GERD and tooth wear in bruxism patients. A cohort of 363 consecutive bruxism patients and 363 matched control participants were recruited. Gastroesophageal reflux disease was diagnosed in accordance with the Montreal criteria. Tooth wear was scored based on the index recommended by Smith and Knight. Logistic regression analyses were performed. After adjustment, GERD was identified as a risk factor of bruxism. Bruxism with reflux symptoms for extensive time-periods was associated with severe tooth wear for the whole dentition (odds ratio, 4.70, 95% confidence interval, 2.04–10.83). Increased odds ratios for severe tooth wear were also found in all tooth locations and palatal/lingual and occlusal/incisal surfaces of bruxism patients with GERD for extensive time-periods. In conclusion, strong associations were identified among bruxism, GERD, and tooth wear.

Is histologic esophagitis associated with dental erosion: a cross-sectional observational study?

Background

Gastroesophageal reflux disease (GERD) affects 15–25% of children and adolescents in the United States. The diagnosis of GERD in children is complex as reported symptoms or symptom profiles have been found to be unreliable. Frequently, the diagnosis must be confirmed by objective tests such as pH monitoring or histological evidence of esophagitis on an esophageal biopsy. Dental erosion has been shown to be associated with GERD as an atypical complication and has the potential to be a marker of GERD. The purposes of this study were to compare the frequency and patterns of dental erosion in children and adolescents with and without histologic esophagitis.

Methods

Twenty-five subjects were recruited from patients scheduled for an upper gastrointestinal endoscopy. Information regarding potential GERD symptoms, food habits, and dental hygiene habits were obtained. Intra-oral photographs were taken, and a dental exam for erosion was performed. The results of a standard biopsy taken from the lower third of the esophagus during an endoscopy were used to divide subjects into either the control group or the GERD group (i.e. those with histologic esophagitis).

Results

Twenty-two subjects yielded 586 evaluable teeth. No significant difference was found between frequency or erosion patterns of those with and without histologic esophagitis. Dental erosions were more frequent in primary teeth.

Conclusions

Dental erosions do not appear to be associated with histologic esophagitis indicative of GERD.

Rumination Syndrome and Dental Erosions in Children

Rumination syndrome is the effortless regurgitation of recently ingested food with subsequent reswallowing or spitting out. Dental erosion (DE) affects 2% to 5% of the population. DE is defined as loss of tooth structure by a chemical process that does not involve bacteria. Our objective was to compare the frequency of DE among children with rumination syndrome with healthy controls. We enrolled 30 patients 4 to 21 years of age diagnosed with rumination syndrome, and 30 age- and sex-matched healthy control subjects. Patients were evaluated by pediatric dentists for presence of DE with Taji et al a validated grading system. Patients with rumination were more likely to have DE (P < 0.001). Of patients with rumination syndrome, 23 (77%) had DE, compared with 4 (13%) control subjects. DEs are more frequent in patients with rumination syndrome.

Prevalence of dental erosion among people with gastroesophageal reflux disease in China

STATEMENT OF PROBLEM

Gastroesophageal reflux disease (GERD) is typically diagnosed based on symptoms of regurgitation and heartburn, although it may also manifest as asthma-like symptoms, laryngitis, or dental erosion.

PURPOSE

The purpose of this prospective, cross-sectional study was to assess the prevalence of dental erosion in people with GERD and to evaluate the association between GERD and dental erosion.

MATERIAL AND METHODS

The presence, severity, and pattern of dental erosion was assessed in 51 participants with GERD and 50 participants without GERD using the Smith and Knight tooth wear index. Medical, dietary, and dental histories were collected by questionnaire. Factors potentially related to dental erosion, including GERD, were evaluated by logistic regression.

RESULTS

Dental erosion was observed in 31 (60.8%) participants with GERD and 14 (28%) participants without GERD. Bivariate analysis revealed that participants with GERD were more likely to experience dental erosion (crude odds ratio [cOR]: 2.74; 95% CI: 1.19, 6.32) than participants without GERD. Multivariate analysis also revealed that participants with GERD had a higher risk of dental erosion (adjusted odds ratio [aOR]: 3.97; 95% CI: 1.45, 10.89). Consumption of grains and legumes, the most frequently consumed foods in China, did not correlate with dental erosion. However, carbonated beverage consumption was significantly associated with GERD and dental erosion (aOR: 3.34; 95% CI: 1.01, 11.04; P=.04).

CONCLUSIONS

GERD was positively correlated with dental erosion. Carbonated beverage consumption can increase the risk of both GERD and dental erosion.

Acid Rather Than Nonacid Reflux Burden Is a Predictor of Tooth Erosion

OBJECTIVES

The relation between tooth erosion (TE) and gastroesophageal reflux in children has not been clearly established, and there are no studies to determine the relation with refluxate height, nonacid reflux, and erosions. The aim of this study was to determine the relation between TE and acid and nonacid gastroesophageal refluxes measured using combined pH and multichannel intraluminal impedance (pH-MII).

METHODS

We conducted a prospective cohort study of children presenting for pH-MII testing. Once informed consent was obtained, patients completed questionnaires about their reflux symptoms and diet, and then underwent pH-MII catheter placement and a dental examination. The Keels-Coffield erosion index was used to score the extent and severity of TE. Reflux parameters of patients with and without TE were compared using Student t test and correlations were performed using Spearman correlations.

RESULTS

A total of 27 patients participated in the study, all of whom were on acid suppression at the time of pH-MII testing. Of the 27 patients, 10 (37%) had TE. There were significant positive correlations between acid reflux episodes (r = 0.44, P = 0.02), the percentage of time that acid reflux was present in the distal esophagus (r = 0.44, P = 0.02), and reflux index (r = 0.54, P = 0.004) with the number of TE in a given patient. The percentage of time that acid reflux was present in the proximal esophagus was positively correlated with the number of teeth erosions per patient with borderline significance (r = 0.38, P = 0.05).

CONCLUSIONS

There was a positive correlation between acid reflux parameters and TE. Acid, rather than nonacid reflux, seems to have a significant role in the pathogenesis of TE.

Erosive esophageal reflux vs. non erosive esophageal reflux: oral findings in 71 patients

BACKGROUND

The purpose of this clinical study was to assess the prevalence of acidic oral mucosal lesions and periodontal conditions in patients suffering from erosive esophageal reflux disease (ERD) compared with non erosive esophageal reflux disease (NERD) patients, both treated with long term proton pump inhibitors (PPI).

METHODS

Seventy-one patients with diagnosed GERD were studied: i.e. 29 ERD and 42 NERD patients. Thorough visual examination of the oral mucosa and a periodontal evaluation was performed. The primary outcome was defined as a statistically significant difference, between the two groups, in the presence of acidic lesions of the oral mucosa and specific periodontal parameters.

RESULTS

This study failed to demonstrate statistically significant differences between ERD and NERD patients with respect to the prevalence of oral mucosal lesions. However, significantly more ERD patients suffered from severe periodontitis (CAL ≥ 5 mm) as compared to NERD patients. Accordingly, it may be assumed that PPI-use had no adverse effects on the prevalence of acidic oral mucosal lesions and on periodontal destruction.

CONCLUSIONS

Within the limitations of this study it may be concluded that ERD and NERD patients need separate evaluation with respect to periodontal destruction. Moreover, long term PPI medication had no adverse clinical impact on acidic oral mucosal lesions and periodontal destruction. Further studies are necessary to elucidate the role of reflux in the periodontal destruction of ERD individuals.

Dental Erosion in Patients with Gastroesophageal Reflux Disease (GERD) in a Sample of Patients Referred to the Motahari Clinic, Shiraz, Iran

STATEMENT OF PROBLEM

Systematic reviews of the literature show that the dental erosion is associated with the gastroesophageal reflux disease (GERD).The prevalence of the problem may not be exclusively similar in different countries.

PURPOSE

The purpose of this study was to investigate the association of gastro-esophageal reflux disease (GERD) with dental erosion in a sample of Iranian population regarding the standing difference in the Iranian oral hygiene and diet. Material s and Method: 140 patients with the average age of 30 to 50 years old comprised the study group. The participants were already eligible for the endoscopic examination, diagnosed by their gastroenterologist. All patients completed a detailed questionnaire regarding the medical and dental situations. After completing the questionnaire and before endoscopy, dental examination was performed by two blinded dentists.The endoscopy was then performed by a gastroenterologist and the patients were divided into three groups of healthy, suspected to GERD, and positive GERD. Data were collected and analyzed by Chi- Square test. The cross tabulation test was performed to compare the qualitative variants and discover the correlations. The statistical significance was adopted as: p < 0.05.

RESULTS

The prevalence of dental erosion in GERD patients (22.6%) was found to be higher than the suspected (5.3%) and the healthy (7%) individuals.

CONCLUSION

This study declared the GERD patients are at higher risk of developing dental erosion compared to the healthy individuals in a sample of Iranian population.

Gastroesophageal reflux disease and tooth erosion: a cross-sectional observational study

Background/Aims

Gastroesophageal reflux disease (GERD) is common in children. Recurrent exposure to gastric acid in GERD may contribute to tooth erosion.

Methods

In this prospective study, 54 GERD patients qualified according to endoscopy, pH-metry, and the GERD questionnaire and 58 healthy controls qualified by the GERD questionnaire were assessed. Two groups underwent dental evaluations for the presence, severity, and patterns of erosion and for the stage of dentition using a Tooth Wear Index. The health care providers who performed the dental exams did not know which children had been diagnosed with GERD.

Results

A total of 112 children, 3 to 12 years old were enrolled in the study, and 53 of 54 (98.1%) GERD patients and 11 of 58 (19.0%) controls had dental erosions (p<0.0001). In GERD patients, the posterior occlusal surfaces of milk teeth were more affected (p<0.0001). There was no correlation between GERD and the affected surfaces in permanent teeth, nor in the patterns or erosion grades (localized or general). In both groups, milk teeth had more erosions than permanent teeth, but the difference was not statistically significant.

Conclusions

According to this study, there is a positive correlation between GERD and dental erosion. Posterior occlusal surface erosions in milk teeth could indicate GERD.

Risk indicators for dental erosive wear among 18-yr-old subjects in Oslo, Norway

The aim was to investigate risk indicators associated with dental erosive wear among 18-yr-old subjects in Oslo, Norway. Of 3,206 adolescents invited to participate in a screening examination for erosive wear, 1,456 were examined (giving a response rate of 45%). As part of the examination all participants completed a self-administered questionnaire. Associations between the presence of erosive lesions and the possible risk indicators were assessed by logistic regression analyses, taking into account the hierarchical relationships between the independent variables. Of all 18-yr-old subjects examined, 38% had at least one tooth with erosive lesions. Multivariate analyses showed significant associations between the presence of erosive wear and being male, brushing teeth once per day or less, episodes of vomiting, daily/weekly episodes of gastro-oesophageal reflux, consumption of fruit juice and sugary soft drinks several times per day, as well as consumption of sugary soft drinks daily to once per week. In conclusion, in addition to gender, dietary habits such as frequent consumption of fruit juice and sugary soft drinks, and the occurrence of reflux and vomiting, appear to be risk indicators for erosive wear. When counselling adolescents at risk, the gender-specific risk indicators should be taken into account.

Reflux and aerodigestive tract diseases

Gastroesophageal reflux disease can present with a wide variety of extraesophageal symptoms. In particular, the type of disease characterized predominately by laryngopharyngeal reflux may be difficult to diagnose because of the absence of regurgitation or heartburn. The available battery of diagnostic tools is often insufficient to confirm a diagnosis of reflux, so the diagnosis is often made by elimination. In many cases, treatment with proton pump inhibitors will relieve symptoms and respiratory complications, despite the persistence of non-acidic reflux. Such treatment is often employed to "confirm" the diagnosis, as measured by patient response. Many diseases have been related to this condition in the literature. The authors review knowledge about these manifestations and their relationship with refluxed gastric content. Physiopathology, symptoms and treatment are reviewed in order to clarify our understanding of laryngopharyngeal reflux diseases and related manifestations.

Gastroesophageal reflux disease and tooth erosion: SEPAHAN systematic review no. 10

Many systemic diseases affect oral health. The aim of this research was to conduct a systematic review on the association between dental erosion (DE) and gastroesophageal reflux disease (GERD) and the effect of saliva's flow rate, buffering capacity and oral microbial changes caused by GERD. All descriptive, analytical studies up to December 2011 that have relevant objectives, proper sampling method and sufficient results were included by searching PubMed and Scopus electronic data bases. Fifteen studies were selected according to our inclusion criteria (10 in adult and 5 in children population). There was a strong association between DE and GERD in the adult population, and the relationship in the children population was found to be of less importance. Early diagnosis and treatment of refluxed acid in both age groups through lifestyle changes and medications can prevent further damage and tooth loss.
