Feasibility of Unwaxed and Waxed Banana (Musa acuminata x balbisiana) Pseudostem Fibers as Alternative Dental Floss Material

Oral health, waste management, and sustainability are prevalent issues faced by developing countries. Relative to these concerns, there remains a need for oral hygiene essentials that are both effective and environmentally responsible. This study aims to explore the feasibility of banana pseudostem fibers (BPF) as an alternative material for sustainable dental floss in terms of two physical properties, namely, tensile strength and elongation at break. Fibers were mechanically extracted from the outermost sheaths of banana pseudostems to produce two sample groups, unwaxed BPF and waxed BPF, the latter comprising fibers that were coated with a mixture of two parts coconut oil and one part candelilla wax. Both sample groups were tested for tensile strength and elongation at break. According to the mean and SD of both groups and one-way MANOVA, unwaxed BPF had significantly higher tensile strength and elongation at break than waxed BPF, revealing that the wax coating process diminished the physical properties of the BPF due to thermal degradation. Furthermore, the application of the coconut oil-candelilla wax coating was found to have a large effect on tensile strength and a small effect on elongation at break. Results show that there is potential in BPF to be an alternative material for dental floss in relation to the examined properties, although it may not be a substitute for synthetic dental floss material by itself. Modifying the fiber extraction and wax coating processes involved and assessing the chemical properties of the material are also recommended for further research
