Erosive Effect of Analgesics on Primary Tooth Enamel - An in Vitro Study

Objective: To evaluate in vitro erosive effect of analgesics on primary tooth enamel. Material and Methods: The pH the titratable acidity measurements medicines were performed triplicate using a digital meter. Enamel slabs teeth flat polished selected by initial surface microhardness analysis. Medications specimens assigned into five groups (n=12): Dalsy; Magnopyrol; Paracetamol; Tylenol; distilled water (negative control). Specimens immersed 5 ml each group solution for 30 min, 4x/day three days stored artificial saliva at 37 °C between immersions night. Final was determined. data submitted to Oneway ANOVA Tukey's test. Scanning electron microscopy (SEM) analysis group. Results: Medicines showed acidic mean values ranged from 1.46 11.66 0.1N NaOH. mineral loss Magnopyrol statistically significant relation control (p<0.01). higher when compared Tylenol (p<0.05). SEM images displayed microstructure alterations Paracetamol Conclusion: Despite low values, only greater enamel softening. demonstrated morphological changes
