The teeth were placed on the frasaco arches and were mounted in the frasaco head. The preparations were examined </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>for the tapering, presence of undercuts, incisal and cingulum reductions as well as preparation of shoulder margin. Preparations </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>were examined using hand instruments and visual. The sample size was 92 plastic teeth. Most of the preparations were acceptable </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>with acceptable placement and types of margins, adequate axial and incisal reductions and acceptable tapered of the axial walls. On </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>the other hand, most of the teeth showed absence of cingulum wall. Most of the crowns prepared by the students were acceptable. It </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>showed that they understood the principles of crown preparation. Cingulum wall preparation has to be given greater emphasis as it </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>is important in the retention and resistance of the restoration.</em></span></span></span></span></span></span></span></span><br style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;" /></span>
