Abstract
Background/purpose: Advanced glycation end products (AGEs) are known to accumulate in the periodontal tissues of patients with diabetes mellitus (DM). Through this study, we aimed to investigate the distribution of AGEs and the receptor of AGEs (RAGE) in the gingival tissues of patients with chronic periodontitis with and without non-insulin-dependent diabetes mellitus (NIDDM). Materials and methods: < 0.05) for the AGE and RAGE rankings of the following clinical parameters: plaque score (PI), probing depth (PD), bleeding on probing (BOP), and tooth loss (TL). Results: > 0.05). A positive correlation between AGE ranking and TL was observed in the NIDDM group, but not between AGE ranking and PI, PD, or BOP. The distribution of RAGE was not correlated with PI, PD, BOP, or TL. Conclusion: AGEs were particularly distributed in the highly inflamed gingiva of patients with NIDDM-associated periodontitis and was statistically correlated with the long-term parameter TL.
