Abstract
Oral health can be influenced by pathology in the gastro- intestinal tract. One such problem that has an effect in the oral cavity is Gastroesophageal reflux disease (GERD) which, according to the WHO has the 40% prevalence among the population of the globe.
Aim: The aim of this study was to compare indicators of the oral health status between patients with two types of GERD a nd w ith t hose o f p atients w ithout G ERD.
Methods: The study took place in 2015/2016 and was approved by the local Ethics Committee of Moscow State University of Medicine and Dentistry. It involved 47 patients aged 18-70 years (average age of 38 years), who were identified by the University Department of Internal Medicine. Patients were divided into three groups: Group 1-control (n=15); Group 2- patients with GERD with acid reflux (n=16); Group 3-patients with GERD with a slightly alkaline reflux (n=16). The following oral parameters were determined: pH and buffer capacity of saliva, the rate of salivary flow, the microbial composition of plaque on the tongue and the , OHI-S and , PMA indices. The results were statistically tested using students t test.
Results: OHI-S in Group 2 was significantly higher (2,47+-0,53) than in Group 1 (1,28+-0,72;p<0,001); in Group 3 OHI-S was higher than in Group 1, but to a lesser extent (2,04+_0,96; p<0,01). The PMA index data in Group 2 were 22,36+_0,64 vs 12,44+_0,44 in Group 1 and 20,77+_0,23 in Group 3. The indicators of salivary flow rate in Group 2 were 0,26+_0,74 vs 0,39+_0,61 in Group 1 and 0,22+_0,78 in Group 3. The results of other studies, including metering pH, buffer capacity of saliva and microbiological analysis are presented in the poster.
Conclusion: Significant changes in indicators of oral health were observed among patients with GERD with the pathological acidic refluxes. There appears to be a need to develop special measures for prevention and treatment of oral problems for such patients.
