Gastroesophageal Reflux disorder (GERD) is a common disorder found in 60% of population. This study aims to investigate the salivary parameters and occurrence of caries, erosion and periodontal disease in GERD patients Objectives: Evaluation and co–relation of the salivary parameters, dental erosion and caries in GERD patients.Methods: The study included 60 patients and they were divided into 2 groups of 30 each. Group 1 –individuals with GERD, Group 2– healthy individuals. The salivary parameters (Salivary flow, pH, buffering capacity) were evaluated in Basic Science Research laboratory and the dental erosion rate was assessed The dental changes were examined and were co–related.Results: Unpaired t test was used for group comparison. Chi square Test was for evaluation of quantitative variables. The salivary pH in Group 1 was 6.70 and in Group 2 it was 7.07. The salivary buffering capacity was comparable in Group 1 and Group 2which was 5.50 and 5.06 respectively. Mean DMFT score was 4.73 and 9.25 respectively. 63.34% of Group 1 patients had Grade 1 erosion and periodontal problems. The co–relation between salivary pH and buffering capacity was estimated by Karl pearson’s co–efficient.

Conclusion:The present study revealed a reduced salivary pHand no significant reduction in salivary buffering capacity and salivary flow rate in GERD patients. Caries rate was less and dental erosion rate was higher in these patients. There is a significant association between GERD, tooth erosion and dental caries.
