Interpretation and Conclusion : Low pH soft drink caused highly significant microleakage at the tooth and restorative material interface in medium and high immersion regimes signifying that the leakage pattern was directly proportional to the number of immersions.

On comparing the microleakage scores of FiltekTM flow when exposed to the Cola group, fresh fruit juice (orange) group and water (control) under the low, medium and high immersion regimes, it was evident that the microleakage showed an increasing trend in the Cola group as compared to the fresh fruit juice and control groups.
The VitremerTM restoration specimens showed a trend of increasing microleakage as the number of immersions increased especially in the Cola group 23 from their study inferred that as the period of exposure increased, so did the severity and depth of erosive lesions. 23 The pH of the acidic drinks also played a major role, as it might be true that higher microleakage scores were due to much of the restorative materials being removed along with the enamel. 11 However, it is inappropriate to extrapolate the findings of our study to the conditions existing in vivo in humans.
