Abstract

To evaluate the effectiveness of digital scanning methods in dental education  to reduce the rate of damage to the adjent teeth in CL II cavity preparations  Materials and Methods: As a part of cavity preparation lecture ; after teaching them how to open cavities without any deformation to the adjent teeth ;  245 Dental students were asked to prepare classical Class II cavity preparations both in maxiller and mandibular first molars in phantom models.  Mesio-occlusal class II cavities for maxiller first molar-16 were performed  and disto-occlusal Cl II cavities performed  for mandibular 1 molar-36. All adjent phantom  teeth  surfaces were examined using visual examination then randomly 50  phantom models were selected  and  all adjent phantom  teeth  surfaces of that selected group were examined using 3D digital scanning methods.  Examination  of teeth surfaces were done  by calibrated individual examiners in all groups. After examination, 50 selected performance owners were informed about their  Iatrogenic damages.  All 245 dental students were taken under a course again to teach them how to reduce iatrogenic damages for class II cavity preparations. The same procedures were repeated and students were asked to do same the work with the same teeth. Damages were scored as 0= no damage, 1= abrasion 2= injury  <50% of surface,  3= injury  > 50% of surface. Results: A rate of nearly 27 % less damage was found to the adjent teeth with the group that was  shown their mistakes by digital scanning methods. After 2 courses, we still obtained  iatrogenic damages  Conclusion: According to our results of  damage to the adjent teeth in CL II cavity preparations, additional teaching of protection of these surfaces  is needed to reduce the rate. Also, the use of 3D scanning methods seems to be helpfull for us to obtain more successful results  from cavity preparation teaching  without   the iatrogenic damages of adjent teeth.
