Correlation between salivary immunoglobulin A and interleukin-1beta in smokers with dental caries

Introduction. Dental caries is one of the most common infectious diseases of the oral cavity, and is an inflammatory disease caused by several factors. Interleukin-1β (IL-1β) is a major mediator of acute inflammation and essential for the development of specific immune responses. The objective of th...

Sumario:Introduction. Dental caries is one of the most common infectious diseases of the oral cavity, and is an inflammatory disease caused by several factors. Interleukin-1β (IL-1β) is a major mediator of acute inflammation and essential for the development of specific immune responses. The objective of this study was to assess the levels of secretory IgA (s-IgA) and IL-1β in the saliva of smokers with dental caries, and to discover the correlation between these parameters and dental caries. Methods. Saliva samples were collected from 30 smokers, age range 21–70 years, with dental caries, in addition to 18 healthy non-smoker volunteers, age range 21–65 years. s-IgA and IL-1β levels in the saliva samples were estimated by enzyme-linked immunosorbent assay (ELISA). Results. The mean saliva IgA levels between smokers with dental caries group and healthy subjects were not significantly different (p=0.077), while the saliva levels of IL-1β were higher in the smokers in dental caries group, with a significant difference of p<0.05. No significant associations were found between s-IgA and IL-1β levels, and other parameters such as age, sex, body mass index (BMI) and C-reactive protein (CRP) (p>0.05). There were highly positive associations and significant differences between IL-1β and CRP levels in the two groups under the study (p=0.006). Conclusions. Our study revealed a significant increase in IL-1β levels in saliva of smokers with dental caries, and a positive association between IL-1β levels and caries disease. There is no significant relationship between elevated IL-1β levels and s-IgA in smokers with dental caries.
