Materials and Methods: 2000 of medically compromised patients were involved in the study, their ages ranged from 16-60years.Organoleptic scoring assessment, WHO DMFT index (1997), WHO basic periodontal disease index (1977) were recorded. Questionnaires were used to obtain past medical history. Result: There were 698 patients (34.9%) of the examined patients suffering from different degree of halitosis. Oral malodor was significantly related to old age, low educational level(p<0.05), oral causes as [tongue coating, tonsillitis, lip and palatal ulcers(p<0.05)] ,WHO1997 DMFT index and WHO 1977 periodontal index (p< 0.05), oral hygiene measures[time of brushing/day, mode of flossing(p<0.05)] oral intake[dietary intake, snacks causing halitosis (p<0.05)]medications[number and type of medicaments(p<0.05)] systemic diseases[diabetes mellitus145 patients(20.8%) was higher percentage of other systemic diseases and (p value<0.05 and sinusitis(p<0.00). Conclusion: halitosis is prevalent with high degrees among patients who are old age ( 46-60years) males with lower educational level, live in rural area had tongue coating ,tonsillitis, advanced periodontitis, High DMFT index with mean17.45,not flossing or vigorously floss their teeth, eating and drinking diet causing halitosis with snacks more than one time daily, taking drugs more than 3 types and suffering from diabetes mellitus and sinusitis.
