Nasution, A., Babu, S. 2018. Differences of salivary urea levels in plaque-induced gingivitis and periodontally healthy patients in Periodontology Clinic of The Faculty of Dentistry North Sumatera University (USU) Medan. Journal of Dentomaxillofacial Science 3(2): 112-114. DOI:10.15562/jdmfs.v3i2.757


Objective: This study aims to know the difference of urea levels in saliva of plaque-induced gingivitis patients and in healthy patients at the Periodontology Clinic of Faculty of Dentistry USU.

Material and Methods: This analytical study used a spectrophotometer to see urea levels in 30 salivary samples of gingivitis patients and healthy patients.

Results:  After the samples were analyzed, it was found that the urea level in saliva of gingivitis patients was higher with the mean score of 52.062 g/dL whereas the urea level in saliva of healthy patients was 26.614 g/dL. The results of this study are in line with several studies conducted using various methods and samples.

Conclusion: The urea level in saliva of plaque-induced gingivitis patients was significantly higher when compared with healthy patients.
