RESUMO
Introduction Dental erosion is defined as a non-carious lesionhaving superficial tooth loss initiated by a chemical processeither intrinsic or extrinsic, without involvement of bacteria.The incentive of this study was to assess and compare dentalerosion associated with the intake of carbonated drinks amongdental students; day scholars and hostel residents of theUniversity College of dentistry, Lahore.Materials and Methods: A cross-sectional descriptive studywas carried out on 183 dental students. Dental erosion wasestimated using the index of Basic Erosive Wear Examination(BEWE).Results: 31.6% hostel residents and 11.2% day scholarsconsumed carbonated drinks multiple times daily. Highererosion index values were seen in hostel residents than dayscholars. 48.6% was the prevalence of dental erosion amongthe study participants.Conclusion: Hostel residents consume more carbonateddrinks than day scholars. Erosion of teeth by carbonated drinksis influenced by the frequency, quantity, type, carbonateddrinks temperature and persons drinking habits.
