Abstract

The ancestors in Indonesia often do nginang activities as a culture of hereditary.

The results concluded that nginang culture is able to strengthen the teeth, because in betel contains essential oil from phenyl propanoid and tannin compounds. Essential and tannin essential oils are antimicrobial and antifungal properties are strongly suspected and can inhibit the growth of certain types of Escherichia coli, Salmonella sp, Staphylococcus, and Candida albicans bacteria. In Nginang culture is technically mixing betel leaves with some chemicals contained the concept of mixed chemistry, acid-base reaction, and substance changes. The results of the analysis on the answers of sources obtained various information related to how to produce Nginang ingredients composition, so that obtained the taste and benefits for dental health
