The purpose of the study was to evaluate the awareness of periodontal health among the patients visiting dental OPDs of Altamash Institute of Dental Medicine Karachi. This survey was conducted from September,2019 to November,2019. A descriptive crosssectional survey was conducted on 100 patients. A structured questionnaire was administered through convenience sampling to patients. The results of the questionnaire were calculated and analyzed via the SPSS software version 20. Periodontal health depends on the maintenance of the periodontium which includes gingiva, periodontal ligament, cementum, and alveolar bone [1]. Periodontal disease that adversely affects one of these components, has been a leading concern in our part of the continent [2]. Oral health plays a pivotal role in ensuring sound mental and physical health of an individual [3]. The association between one's general health with that of his oral health cannot be ignored as the oral cavity is a reflection of general health [4]. For instance, various studies were undertaken to prove a bidirectional relationship between periodontal disease and diabetes [5]. There is abundant evidence indicating the correlation between oral health and lack of awareness amongst the people coming from different socioeconomic backgrounds [6]. In a third-world country like Pakistan, the majority of the population is completely oblivious to the different measures of oral health maintenance and harbor destructive habits like betel nut chewing. Their negligence often accounting for premature tooth loss, gingival bleeding, swelling, pain, food impaction and general discomfort amongst the masses irrespective of their age, gender or economic status.Periodontal disease progresses after accumulation of plaque, which is a biofilm that contains microorganisms, and the subsequent lack of physical removal of the plaque resulting in calculus, hardened plaque [7]. This leads to the development of periodontal deterioration in the presence of decreased host resistance and lack of preventive measures such as self-care and frequent dental visits.
