Abstract

Kebiasaan merokok diketahui meningkatkan kandungan ion kalsium saliva. Peningkatan kandungan kalsium tersebut dikarenakan rokok menyebabkan menyebabkan terjadinya penurunan laju aliran saliva dan peningkatan kandungan ion kalsium pada saliva. Berdasarkan hal tersebut telah dikembangkan metode untuk mengetahui perbedaan karakter spektral dari unsur kalsium dalam saliva yang berasal dari perokok ringan, sedang dan berat menggunakan LIBS (Laser-Induced Breakdown Spectroscopy). Berdasarkan hasil penelitian, kondisi optimum pengujian ditentukan dengan delay time 0.5µs, energi laser 100 mJ dan akumulasi 3 kali penembakan, dan kondisi lingkungan gas atmosfer. Unsur-unsur yang terdapat di dalam saliva di antaranya adalah 99% air dan sisanya adalah komponen anorganik seperti natrium, kalium, magnesium, kalsium, fluor. Unsur Ca (kalsium) merupakan unsur anorganik yang dominan terdapat dalam saliva yaitu berperan dalam proses buffering rongga mulut. Berdasarkan data penelitian diperoleh bahwa peningkatan jumlah konsumsi batang rokok perhari oleh responden penelitian diikuti dengan peningkatan intensitas emsisi unsur Ca pada panjang gelombang 422.67 nm. Hal ini dibuktikan dengan adanya peningkatan rata-rata intensitas unsur Ca pada saliva sebesar 30% pada kelompok perokok ringan dibandingkan kelompok non-perokok, sebesar 37% pada kelompok perokok sedang dibandingkan kelompok non-perokok, dan sebesar 51% pada kelompok perokok berat dibandingkan non-perokok. Peningkatan ini menunjukkan bahwa terjadi proses demineralisasi (kelarutan) unsur Ca pada enamel gigi ke dalam saliva. Analisa regresi menunjukkan nilai R= 0.99735, nilai R2 = 0.9947, dengan persamaan y=12.867x-29.505 dan standar estimasi (SE) = 0.236897. ================================================================================================================== Smoking habits are known to increase levels of calcium ions saliva ions. Increased levels of calcium due to cigarettes can cause a decrease in salivary flow rate and increased concentration of calcium ions in the saliva. Based on the problem above, a method has been developed to analyze the calcium element in saliva using LIBS (Laser-Induced Breakdown Spectroscopy). Based on the research results, the optimum conditions of the test were determined with 0.5μs time delay, 100 mJ laser energy and 3 accumulations of shoot, and at an atmospheric gas conditions. The elements present in the saliva are 99% composed of water and some anorganic elements such as sodium, potassium, magnesium, calcium, fluorine. Ca element (Calcium) is a prominent element contained in saliva that acts mostly in buffering process of the oral cavity. The result data showed that that an increase of cigarette consumption per day was followed by the increase of Ca emission intensity at wavelength. There is a 30% increase in Ca emission intensity of light smoker group compared to non-smoker group, a 37% increase in Ca emission intensity of the moderate smoker group compared to the non-smoker group, and 51% in Ca emission intensity of the heavy smoker group compared to the non-smoker group. This result indicates that a demineralisation (solubility) process has occurred which is related to a dissolution of Ca element in tooth lattice into saliva due to the smoking habit. Regression analysis showed the value of R = 0.99735, R2 = 0.9947, with the equation y =12.867x-29.505 and standard estimation (SE) = 0.236897.
