The purpose of the investigation was to determine the effect of drinking a natural mineral dietary supplement (NMDS) on gingival health and dentinal hypersensitivity. The NMDS product was from a geothermal source and contained 3.6 mg l −1 of fluoride and other minerals. Sample selection included subjects with gingival inflammation and sensitivity as well as screening for exclusion factors. A double‐blind randomized parallel approach was used. The investigation was a quasi‐experimental pre/post‐test design. The experimental group ingested and swished twice a day with the NMDS (1 l) and the control group followed the same regimen with a placebo containing de‐ionized water (DIW). Clinical measurements of gingival inflammation and dentinal sensitivity were taken at baseline, 4 and 8 weeks. Gingival inflammation was measured using the Gingival Index. Dentinal hypersensitivity was measured using a tactile stimulus and an evaporative stimulus. After each stimulus was applied, the subjects rated the amount of discomfort on a visual analogue scale from 0 to 10. Each set of data was analysed using anova and a post hoc probing technique to determine within‐ and between‐group differences ( P = 0.05). The experimental and control groups ( n = 70) experienced a statistically significant decrease in tactile and evaporative sensitivity scores over time; however, the between‐group differences were not significant. The gingival inflammation data were not statistically significant with regard to the within‐ and between‐group differences. Therefore the NMDS and DIW were equally effective in reducing dentinal hypersensitivity and neither product effectively reduced gingival inflammation.
