 This study examined the levels of salivary interleukin one beta ill one beta in subjects with healthy periodontium and those with gingivitis or periodontitis at different stages. The results showed that there were statistically significant differences among the study groups with the experimental groups showing higher levels than the control group. Additionally, the gingivitis group had significantly higher levels than the stage two and three groups. This suggests that ill one beta may be a useful by marker for distinguishing between healthy and unhealthy periodontium. This article was authored by Munthadra A. Almosabi and Omer A. Chalee.
