Survey of contemporary methods of restoring endodontically treated teeth in Riyadh area-Part II: premolar teeth

Restoration of endodontically treated teeth is an area of controversy and divergence of opinions. This study was initiated to detect the frequency of the preferred methods of restoring endodontically treated premolars in different clinical conditions. A questionnaire form was distributed among prosthodontists and general practitioners in Riyadh area. They were asked to indicated their year and institution of graduation, degree and current institutions. Responses from 150 dentists were collected and statistically analyzed. The results indicated that most of respondents preferred to use amalgam restorative material (54%) when more than 50% of sound tooth structure remains (condition A). When about 50% of the sound tooth structure remains (condition B), most of respondents preferred to use a restorative material/crown (37.3%). However, when less than 50% of the sound tooth structure remains (condition C), 72.7% of respondents preferred to use a cast post and core/crown. When those premolars were used as abutments for fixed or removable partial dentures, respondents changed their choice of restorative treatment to more advanced ones. Other factors may affect the choice of restorative method. It can be concluded that most of respondents had the ability to select the appropriate restorative method of the endodontically treated premolar teeth
