| ABSTRACTBackground: Obesity is a complex multifactorial chronic diseasethat affecting the host immunity which may stimulatea hyperinflammatory response in periodontal disease. The aim of the study is to determine and compare the gingivalclinical parameters between Obese, pre-obese, and normal weight. Along with estimating the effect of overweighton healing process of experimental gingivitis, also to determine and compare the microbiological findings betweenObese, pre-obese, and normal weight.Materials and Methods: Our study dealing with experimental gingivitis using the clinical parameters (plaque indexand gingival index), existent bacterial flora, oral hygiene improvement on normal weight, pre-obese, and obesesubjects showing healthy systemic condition, using the body mass index (BMI) and inter parametric comparison on 30individuals, male with no previous medical history, age ranged from 20-30years old,10 of them are obese, 10 arewithin overweight(pre-obese) and the other 10 are within normal weight.Dental plaque samples were taken fromeach subjects when the gingiva reaches inflammation (Mean GI≥1).Results: The G.I .parameter showed a significant higher score of inflammation on the pre-obese and obese samplesduring the initiation of the disease (P≤0.002), and also showed a prolonged improvement response after the recoveryof the oral hygiene control (P≤0.001).The bacterial findings showed an equal percent of streptococci andstaphylococci but with predominance on other species in normal weight subjects. The pre-obese showed anincrease percent of klebsiella .The obese subjects showed insignificant differences and almost equal percent ofstreptococci, staphylococci and pseudomonades with undetectable number of klebseila.Conclusion: This study found that Obesity is an active risk factor for gingival and periodontal disease, and it’s playinga role in elevating body response to dental plaque with increasing the healing period.Key words: Obesity, experimental gingivitis, microbiology, healing period.
