Dissolution of Inorganic Phosphorous Ion from Teeth Treated with Different Concentrations of Aqueous Extract of Nigella Sativa (Black Seed) in Comparison with Sodium Fluoride: An in Vitro Study

Background The medicinal plants which were provided by nature and explored by human to disclose its appreciated values in the clinical field. Black cumin seed have important activity on both human's general and oral health. This study had been used to evaluate the ability of Nigella Sativa aqueous extract to increase tooth resistance against acid attack when compared to Sodium Fluoride. Materials and Methods Twenty five maxillary human premolars were used and treated with the selected solutions as three aqueous extracts of the Nigella Sativa (3%, 5% and 7%) and Sodium Fluoride (0.05% NAF) as control positive, for 2 minutes once daily For 20days time interval, de ionized water was used as control negative.2NHCL etching solution was used and the atomic flame spectrometer was used to measure the concentration of the phosphorous ion release. Result the least phosphorous ion release from the etched enamel was found in the 7% black seed aqueous extract then 5% aqueous black seed extract followed by 0.05% Sodium Fluoride, statistically highly Significant difference between each two groups except that there was statistically significant result between the two aqueous black seed extracts (3% and 5%) and between 3% and 0.05% NAF (sodium fluoride) and statistically not significant difference between 5% Nigella-sativa aqueous extract and0.05% NAF. Conclusion Nigella Sativa aqueous extract registered a mark able benefit of increase tooth resistance against acid dissolution thus it should be used not from Islam view but from its welfare of the mankind and its beneficial effects on people
