Aim: The aim of the study was to evaluate the efficiency of dental students and new graduates of College of Dentistry, King Saud University, in Riyadh, Saudi Arabia, to select the appropriate methods of restoring endodontically treated posterior teeth (ETPT) at different conditions of remaining sound tooth structure. Materials and Methods: A questionnaire was distributed among the 4th- and 5th-year dental students and new graduates. Respondents were requested to indicate their gender and level of education and to select the preferred restoration of ETPT at different conditions. Results were analyzed using one-way frequency and two-way cross-tabulations. Results: At >50% tooth remaining (condition A), 39.9% of the respondents preferred to use an amalgam restoration, while 30.9% preferred to use a restoration followed by a crown at 50% of remaining tooth (condition B). At <50% tooth remaining (condition C), 74.6% preferred to use a cast post-and-core and a crown. Respondents changed their choices of restoration to more advanced ones when teeth served as abutments for fixed or removable prostheses. Chi-square analysis demonstrated a statistically significant relationship between the selected restorative method at condition A and both gender (P = 0.045) and level of education (P = 0.001), between the method of restoration at condition B and both the gender (P = 0.000) and the level of education (P = 0.003), and between the selected restorative method at condition C and the level of education (P = 0.000). Conclusions: Respondents demonstrated a high knowledge when selecting the appropriate method of restoring ETPT at different clinical conditions.
