Perbedaan Akumulasi Plak Antara Perokok dan Bukan Perokok pada Mahasiswa Universitas Sumatera Utara

Abstract

In general, smokers have different oral hygiene compared to non-smokers. Tar and nicotine are the most dangerous chemicals in cigarette smoke. Tar can cause changes in the surface of the teeth to become rough which can increase the attachment of food debris to the teeth so that plaque accumulation also increases. Nicotine can interfere with the immune response, resulting in an imbalance between the number of plaque bacteria and the immune response of smokers. The main objective of this study was to analyze the plaque accumulation of smokers and non-smokers and to find out whether there was a difference between the plaque accumulation of smokers and non-smokers at the University of North Sumatra students. This research is an observational analytic study with a cross sectional design. The number of subjects taken was determined through the sample size formula for the hypothesis of two data groups with a total of 80 subjects studied. Data was collected through interviews, filling out questionnaires and examinations conducted directly by researchers. Based on the results of this study, the most smokers and non-smokers found plaque accumulation in the moderate category, the average PCR score in smokers was 28.56% and non-smokers were 23.38%. The results of the independent t-test showed that there was a significant difference with p value = 0.03 in plaque accumulation between smokers and non smokers of USU students and there was also a significant difference with p value = 0.004 in plaque accumulation in non-smoking subjects between health faculty students and non health USU.
