Abstract

Background: It is well-established that diabetes alters the oral environment, particularly the composition and acidity of saliva, which can affect the microbial balance in the oral cavity. This study investigates the impact of oral acidity disturbances on the growth of pathogenic bacteria in diabetic patients. Saliva samples were collected and analyzed to measure pH levels, acid neutralization capacity, and microbial composition. The results indicate that: diabetic patients exhibit a lower saliva pH compared to non-diabetic individuals, creating favorable conditions for the proliferation of pathogenic bacteria such as Streptococcus mutans, Candida albicans, and Porphyromonas gingivalis. Oral acidity disturbances were positively correlated with increased bacterial colonization and a higher risk of oral infections. Conclution :These findings highlight the importance of monitoring oral health in diabetic patients and suggest that maintaining oral acid balance may play a crucial role in preventing the growth of pathogenic bacteria and their associated complications.
