Abstract
Background. Burning mouth syndrome (BMS) is an intraoral burning sensation for which no medical or dental cause can be found. Since a decrease in pH of oral mucosa below 5.5 is harmful for hard and soft tissues, it can be a result of a decrease in pH.
Objectives. The aim of this study was to compare the salivary pH of patients with burning mouth syndrome to that of healthy subjects in elderly patients.
Material and Methods. The study sample consisted of 50 elderly patients selected by stratified sampling technique from 28 sanitariums in Tehran. A group of 25 cases of BMS and a control group of 25 patients not suffering from BMS were formed. The saliva was collected for 15 min as unstimulated salivary flow. The salivary pH was measured by pH meter and all the data was analyzed statistically with SPSS version 20 and the difference between salivary pH of BMS patient and the control groups was compared with T-test. In addition, logistic regression was also used to determine the effect of variables on salivary pH.
Results. Salivary pH in BMS group was 5.79 ± 0.4 and 5.89 ± 0.7 in the control group. This difference was not statistically significant when compared with T-test (p = 0.93).
Conclusion. In this study there is no difference between BMS patients and the control group in salivary pH.
Streszczenie
Wprowadzenie. Zespół pieczenia jamy ustnej (BMS) polega na wewnątrzustnym pieczeniu, dla którego nie można znaleźć uwarunkowań ogólnomedycznych lub stomatologicznych. Ponieważ spadek pH na błonie śluzowej jamy ustnej poniżej 5,5 jest szkodliwy dla tkanek twardych i miękkich jamy ustnej, to BMS może być związany ze zmniejszeniem pH śliny.
Cel pracy. Porównanie pH śliny pacjentów z BMS z osobami zdrowymi w starszym wieku.
Materiał i metody. Obserwacje prowadzono u 50 starszych osób dobranych warstwowo z 28 sanatoriów w Teheranie. Grupa badana składała się z 25 przypadków BMS, a grupa kontrolna z 25 osób niecierpiących na BMS. Ślina była zbierana przez 15 minut jako ślina niestymulowana. Wszystkie dane analizowano statystycznie i porównywano pH śliny między grupą badaną a kontrolną za pomocą testu t-Studenta. Dodatkowo wykorzystano regresję logistyczną dla oceny wpływu zmiennych na pH śliny.
Wyniki. pH śliny w grupie BMS było 5,79 ± 0,4 a w grupie kontrolnej 5,89 ± 0,7. Różnica między tymi średnimi nie była istotna statystycznie (p = 0,93).
Wniosek. Nie wykazano różnicy w pH śliny między pacjentami z BMS a grupą kontrolną pH.
