Protective effect of two different remineralizing agents on artificially induced dental erosion in primary and permanent teeth: an in-vitro analysis.
Pak Oral Dental J Jan ;37(4):657-66.

The main purpose of this in vitro study was to assess the effect of Chicken Egg Shell Powder (CESP) solution on demineralized enamel surfaces, as well as to compare its effect with those of commercially available Sensodyne Pronamel. Twenty extracted human permanent pre-molars and 20 deciduous molars specimens were cleaned and sectioned longitudinally resulting in 80 samples.40 enamel sections obtained from permanent pre-molars and 40 from primary molars were assigned to the following four groups. Group A: demineralization by soft cola drink, Group B: demineralization by soft cola drink followed by direct application of Sensodyne Pronamel twice a day for a period of 7 days, Group C: demineralization by soft cola drink followed by 7 days’ immersion in CESP, Group D: untreated. The two treatments provided could increase the surface micro hardness values, Calcium and Phosphorous weight percentages in both the permanent and primary teeth. Both CESP (Group C) and Sensodyne Pronamel (Group B) exhibit significantly higher protective anti-erosive effects (p<0.05) but effects of Sensodyne Pronamel was significantly higher than CESP. CESP significantly (p<0.05) increases the micro hardness as well as calcium and phosphorous level of all treated tooth samples. This study demonstrated that both CESP and Sensodyne Pronamel can protect the tooth surface by preventing its erosive enamel loss and enhancing remineralization.
