Abstract
Nowadays, denture adhesive is widely used for denture wearers in order to improve
the denture‘s retention, stability and function especially during mastication. Adhesiveness
plays an important role in denture adhesive, to enhance retention and gives more
psychological confidence for the patient. The objective of this study is to fabricate and
characterize the denture adhesive filled starches and containing antimicrobial agents. Tapioca
starch is chosen as filler as it has proven to exhibit excellent adhesiveness. Several studies
have been reported essential oils such as Peppermint oil, Tea Tree oil (TTO) and Coconut Oil
(CNO) have effectiveness against Candida albicans. Therefore, these essential oils were
chosen in this research. There are several characterization and test were conducted such as
Fourier Transform Infrared Spectroscopy (FTIR), Texture Profile Analysis (TPA), Tensile
Bond Strength (TBD), Shear strength test, pH test, antimicrobial test and morphology study
for Scanning Electron Microscopy (SEM), solubility and swelling test. Denture adhesive with
10% filler loading exhibits the optimum starch composition as it shows highest adhesiveness,
shear strength and elongation at break. However, for tensile bond strength and hardness no
significant trend is observed. Pure essential oils; Peppermint oil and Tea tree oil are proven to
inhibit the bacterial growth, but Coconut oil does not show any zone of inhibition.
Antimicrobial agents in denture adhesive also loss their activity due to low concentration or
denture adhesive deactivate the reaction innate immune molecules in antimicrobial agents.
