Knowledge on Oral Health and Periodontal Status Among Type II Diabetes Mellitus (DM) Patients in Libya

Diabetes mellitus (DM) is one of the common diseases in the world. Its dramatic increase annually is considered a global issue to the people, in which raising awareness about the disease and its complication is crucial. It has been well documented by the literature that smoking and DM are two major risk factors for periodontal disease. Knowledge of oral health is vital for type II DM patients and is a key factor in the treatment and prevention of periodontal disease. A crosssectional study was conducted among three hundred diabetic patients in a Benghazi diabetic treatment center. The participants were 40.3% (n = 121) male and 59.7% (n = 179) female adults whose ages ranged from 16 to 80 years. Inclusion criteria included Libyan citizens diagnosed with type II DM. The participants were questioned through a structured questionnaire and followed by the examination of their oral status. Periodontal examination was performed by two periodontists using the following indices: plaque index (PI) and periodontal disease index (PDI). Knowledge about oral health and periodontal status for Libyan patients with type II DM was tested through eight core questions using a structured questionnaire. The results showed about half of the sample had poor knowledge regarding the condition and its detrimental effect on oral and general health. Only 31% of participants provided good knowledge about type II DM and its relationship to oral health and periodontal status. The P-value showed a significant relationship between the knowledge and PI and PDI indices. Participants with poor knowledge showed higher scores in both indices. A significant relation was found between PI, PDI and knowledge. As knowledge was fair, the lower the PI and PDI scores. To lessen diabetic complications and their deleterious effects on oral and general health, raising knowledge and awareness could be a solution. Multidisciplinary cooperation between the medical and dental staff could be implemented to increase public knowledge.
