PERBEDAAN DAYA HAMBAT PASTA GIGI BERBAHAN HERBAL TERHADAP PERTUMBUHAN STREPTOCOCCUS MUTANS

Abstract

Abstrak
Karies gigi dan penyakit periodontal dapat dicegah dengan mengontrol pembentukan plak secara teratur. Penggunaan pasta gigi herbal dapat memberikan efek kimia untuk mengontrol pembentukan plak. Studi terdahulu mendapatkan bahwa pasta gigi herbal dapat mengurangi jumlah bakteri utama pada rongga mulut yaitu Streptococcus mutans. Penelitian ini bertujuan untuk meneliti perbedaan daya hambat beberapa pasta gigi herbal (mengandung siwak, cengkeh, dan daun sirih) terhadap pertumbuhan Streptococcus mutans. Metode penelitian adalah eksperimental dengan meletakkan cakram yang sudah direndam dengan pasta gigi ke medium agar darah yang mengandung koloni Streptococcus mutans. Uji daya hambat bakteri dilakukan dengan metode difusi. Terbentuknya zona bening di sekitar koloni bakteri menunjukkan adanya penghambatan pertumbuhan bakteri uji. Hasil uji satu arah ANOVA menunjukkan adanya perbedaan daya hambat yang bermakna antar pasta gigi herbal yang digunakan (p<0.05). Ketiga pasta gigi didapakan memiliki kemampuan antibakteri kuat dengan rata-rata zona hambat 16.075 mm, 13.375 mm dan 11.080 mm. Jadi dapat disimpulkan bahwa pasta gigi herbal mempunyai efek anti bakteri terhadap pertumbuhan Streptococcus mutans dengan efek anti bakteri terkuat di tunjukkan oleh pasta gigi mengandung cengkeh.

Abstract
Dental caries and periodontal disease can be eliminated by regularly control plaque formation. The usage of herbal toothpaste is able to give chemical effect toward plaque control. Previous studies shown that the usage of herbal toothpaste was able to reduce the growth of Streptococcus mutans, the main bacteria in the mouth. The study aimed at investigating the difference of zone of inhibition of several herbal toothpastes (siwak- , cloves- , and betel leaves- contained) toward the growth of Streptococcus mutans.This study was experimental research using disc that had been immersed and subsequently put it onto Blood agar medium that contain Streptococcus mutans. Inhibition test of the growth of bacteria was done by using diffusion method and was said as positif result when clear zone surrounding the colony of Streptococcus mutans was identified. One way ANOVA test result showed there was a significant difference of inhibition effect among those three herbal toothpaste (p<0.05). The average diameter of zone of inhibition of clove- , siwak- , and betel leaves-containing toothpaste were 16.075 mm, 13.375 mm and 11.080 mm respectively. Hence, it can be concluded that herbal toothpaste has shown anti-bacterial effect toward the growth of Streptococcus mutans in which the strongest anti-bacterial effect were shown by clove-containing toothpaste.
