One of the most common bacterial infections in people is periodontal disease. its primary reasons for tooth loss. The primary cause of these oral ulcers is the colonization of harmful microorganisms on the surfaces of the mouth. These microorganisms differ based on the lesion under investigation, the length of their development, and the host.

Aim of the study

The study aimed to evaluate the bacterial causes of periodontitis and determined their antibiotic resistance and explain the relation between the bacterial spp. isolate with different patient’s variables.


90 specimens were collected from patients with gingivitis resulting from orthodontic and placement from medical clinics and health centers in Balad district in Salah al-Din Governorate after they were diagnosed in bed with gingivitis by specialist doctors. Swabs of the inflamed gums were taken and then cultured on appropriate culture media and appropriate diagnostic tests were performed, the disc diffusion method were used for antibiotics susceptibility test for all isolated bacteria.


The study showed that periodontitis was most prevalent in teenagers (65%) and in female (63.3%) with mixed diet (61.6%) and urban residence (74.7%). Streptococcus pyogenes was most common isolated bacteria from patients (61.9%) also other bacteria were obtained. Strep. pyogenes was sensitive to Ampicillin, Augmentin and Ceftazidime while resist to metronidazole and tetracycline.


The periodontal status is influenced by numerous patient-related local variables. The most resistant bacteria in the current investigation, Streptococcus pyogenes, demonstrated considerable antibiotic sensitivity.
