Comparison the oral bacteria between diabetic and non-diabetic dental patient in Benghazi city

Background: Recent researches have 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 heath complications. Aim: The aim of our study is to compare the oral bacteria between diabetic and non-diabetic dental patient with multiple antibiotics, which was investigated in Benghazi University, Faculty of Oral and Dental Medicine and Surgery. Methods: A comparative study of oral microbes in normal, non-diabetic and diabetic patient with periodontal disease was performed. In this study, we've used a sample of total 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. Results: showed significant 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 non- diabetic. 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 total of 118) 47,2%. While non- diabetic individuals (male was 38 (15,2%), and female was 74 (29,6%); in total of 112) 44,8%. Conclusion: our study results conclude that certain gram-negative bacteria such as (Pseudomonas and E. coli) may show more abundancy in diabetic patients with periodontitis than non- diabetic individuals. Whereas, Klebsiella exhibited an opposite abundancy situation – found in our study more abundant in non- diabetic individuals than diabetic. Meanwhile; certain gram- positive bacteria such as (Streptococcus mutans) in diabetic patients with periodontitis was most abundant comparing to Viridans Streptococci, Staphylococcus aureus.
