Formulation and Physicochemical Evaluation of a Herbal Dentifrice Formulated with Myristica fragrans (Nutmeg): An In Vitro Study

Aim: Dental plaque is the primary etiological factor of two of the most commonly encountered global oral health problems; dental caries and periodontal disease. The toothbrush-dentifrice combination is an essential aid in preventing them. There are several commercial chemical toothpastes available, but as of late herbal toothpastes have become more popular amongst people. Thus, the aim of this study was to formulate a novel herbal dentifrice with Myristica fragrans (Houtt.) (nutmeg), and compare its physicochemical properties with a commercially available herbal dentifrice without nutmeg. Material and method: A pilot study was conducted wherein the toothpaste was formulated under sterile conditions using various concentrations of nutmeg, tulsi leaves powder and clove powder as the main herbal ingredients. All herbal ingredients were 100% organic and certified by the Food Safety and Standard Authority of India (FSSAI). Its properties were compared and evaluated with a commercial herbal toothpaste and the most optimum formulation was then selected to be a part of the study. The properties evaluated were organoleptic parameters (colour, texture, appearance, taste, odour), pH, foamability, abrasiveness, gritty matter, homogeneity, stability and spreadability. Results: The results revealed that in comparison to the commercial herbal toothpaste, the formulated herbal toothpaste with nutmeg exhibited improved foaming ability, abrasivity, spreadability; and comparable texture, consistency, colour, gritty matter, homogeneity and stability properties. However, it had less favourable odour and taste. Conclusion: The overall results of the research provide convincing evidence of the satisfactory physicochemical properties of the nutmeg toothpaste. However, further research is warranted to test other significant properties of the toothpaste.
