Comparison of the Oral Bacteria between Diabetic and Non-diabetic Dental Patients in Benghazi City

Abstract

ABSTRACT Background: Recent research has emphasized the correlation between infectious microbes in Oral infections (dental caries, periodontal disease, and gingivitis) and diabetes; given that diabetic individuals may suffer from several health complications. So, our research aims to compare the oral bacteria between diabetic and nondiabetic dental patients with multiple antibiotics, which was investigated at Benghazi University, Faculty of Oral and Dental Medicine and Surgery. A comparative study of oral microbes in normal, non-diabetic, and diabetic patients with periodontal disease was performed. In this study, we’ve used a sample of a total of 250 periodontitis patients with a variant age spectrum, sub-grouped into 125 diabetic patients and 125 non-diabetic patients. Using conventional methods of microbial identification, we have been able to clearly label and characterize the isolated microbial content from collected samples. The results showed significantly higher ratios of microbial growth from samples collected from diabetic individuals with dental problems. Not to neglect, the observed results of average microbial growth of certain Gram-positive bacteria (such as Viridans Streptococci, and S. aureus) isolated from diabetic individuals was higher than nondiabetic. However, S. mutans has exhibited a much higher growth in platted samples isolated from non-diabetic individuals than diabetic. The significant microbial growth isolated from diabetic individuals {male was 66 (26.4%), and female was 52 (20.8%); in a total of 118 (47.2%). While non-diabetic individuals {male was 38 (15.2%), and female was 74 (29.6%)}; in a total of 112 (44.8%). Our study results conclude that certain gram-negative bacteria such as (Pseudomonas and E. coli) may show more abundance in diabetic patients with periodontitis than in non-diabetic individuals. Whereas, Klebsiella exhibited an opposite abundancy situation – found in our study more abundant in non-diabetic individuals than diabetic ones.
