Abstract

Saliva is crucial in maintaining oral health, serving various functions such as protecting oral tissues, cleansing the mouth, and aiding digestion. Salivary composition, including pH, buffering capacity, and protein components, has been associated with oral diseases, including dental caries. Tobacco smoking has detrimental effects on salivary glands, altering saliva composition and potentially increasing the risk of dental caries. This study aimed to investigate the relationship between saliva pH and buffering capacity by smoking status and the relationship between saliva pH and buffering capacity by caries risk. A cross-sectional study was conducted among adult smokers and non-smokers visiting the Dental Polyclinics at Universiti Kebangsaan Malaysia (UKM). Salivary parameters, including pH and buffering capacity, were assessed using GC Saliva Check Buffer kits. Caries risk assessment was performed using the American Dental Association Caries Risk Assessment form. Sociodemographic characteristics, smoking status, and caries risk were analyzed using descriptive statistics and chi-square tests. One hundred subjects participated in the study, with 49 smokers and 51 non-smokers. Smokers showed a higher prevalence of high caries risk compared to non-smokers. The buffering capacity of saliva was significantly lower in smokers compared to non-smokers for both resting and stimulated saliva (p<0.001). Resting (p=0.035) and stimulated (p=0.049) saliva pH was significantly more acidic in smokers than in non-smokers. These findings suggest that smoking status is associated with altered salivary parameters and increased caries risk. Understanding the impact of smoking on saliva composition and caries risk can aid in developing preventive and therapeutic strategies for individuals at high risk of dental decay.
