Oral diseases are major health problems with dental caries and periodontal diseases
among the most important preventable global infectious diseases. Oral health influences
the general quality of life and poor oral health is linked to chronic conditions and
systemic diseases. The association between oral diseases and the oral micro biota is
well established. 200 samples collected from 100 patient (children, teenager and adult)
70 female and 30 male with periodontal disease. Rate infection in female with parasite
87.1% more than male, while infected with bacteria, ratio in male 80% more than
female 74.2%. The result shows that 80% from the sample was parasite infection and
76% with bacterial infection. The ratio of infection with parasite increased when the
age of patient increased but no relationship between the age and infection with bacteria.
The type of bacteria isolated belong to in gram positive ,gram negative, aerobic and
anaerobic bacteria. the most bacteria we found was the aerobic bacteria (10 strains)
including Bacillus sp., Staphylococcus sp., Streptococcus mutans, Micrococcus spp.,
Proteus vulgaris, Klebsiella spp., Echerichia coli and Pseudomonas aeroginosae
compared to anaerobic bacteria (4 strains) which include Lactobacillus fermentum,
Actinomyces naeslundii, Peptostreptococcus spp. and Bacteroides ovatus. And 6 strains
of parasite was Entamoeba gingivalis, Trichomonas tenax, Entamoeba coli, Iodamoeba
butschlii, Chilomastix mesnili and Giardia lambelia.
