ABSTRACT
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-oesophageal reflux disease [GERD] with dental erosion in a sample of Iranian population regarding the standing difference in the Iranian oral hygiene and diet
Materials 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 endoscopy 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 analysed 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
