The present cross sectional study aimed to determine the frequency of gingivitis among 21 to 70 old patients at Periodontal Department of Lady Reading Hospital (LRH), Peshawar, Pakistan. A total of 133 patients were observed by using Word Health Organization (WHO) sample size calculator with the following assumption, confidence level = 95%, Anticipated absolute precision = 8% and Population proportion = 33.4%. Standard proforma (questionnaire) and non-probability consecutives sampling technique was used for the sample collection with inclusion and exclusion base criteria for the study fulfillment. Results showed that mean age was 60 years with standard deviation + 8.34. 63 (47.36%) of patients were male and 70 (52.63%) were female. Male patients had gingival inflammation affected more 50 (79.36%) as compared to female 17 (24.28%). Total sample prevalence of mild, moderate and sever gingivitis was 43 (64.17%), 20 (29.85%) and 4 (5.97%). Percentage of mild gingivitis in females was less than males (58.82% vs. 66%), moderate gingivitis percentage was also slightly less in females than males (29.41% vs. 30%). However percentage of females having severe gingivitis was found higher than males (11.76% vs. 4%). Out of 133 patients 67 (50.37%) were analyzed as gingivitis while 66 (49.62%) patients were without gingivitis. It was revealed that the incidence rate of gingivitis was estimated 67 (50.37%) among 133 patients. Patients should need awareness of gingivitis through proper education channel as a result to adopt appropriate oral hygiene practices and other preventive measures to reduce the incidence of this disease and other oral health complications in future.
