Abstract
Endodontically treated teeth (ETT) are more likely to fracture than healthy teeth if left unrestored due to reduced modulus of elasticity and loss of tooth structure. Endodontically treated teeth should be prosthodontically managed properly to add life to the teeth, and hence this study aimed to deter mine opinions, techniques, and materials used on how to restore ETT among general dentists and specialists in Tripoli, Libya, both in the public and private sectors. A two-section questionnaire was distributed either by email (Google Forms) or in hard copies to dentists in Tripoli, Libya. The first section collected demographic information, and the second section of the questionnaire contained 14 multiple-choice questions focused on the treatment strategies of ETT and the materials and methods used for the treatment. Descriptive statistics were used to analyze the data, followed by Chi‑square or Fisher's exact test to compare the responses to different questions among general dentists and specialists. P < 0.05 was considered statistically significant. A total of 176 questionnaires were com pleted. 77% of specialists unbelieve that a post reinforces ETT and reduces fracture probability and they placed posts more frequently as compared to general dentists. 85% of specialists and 58% of general dentists believed that ferrule increases fracture resistance, Fiber reinforced posts were pre ferred by 100% of specialists. Self-adhesive resin cement was selected by 54% of specialists and 10% of general dentists for post-cementation. Most of the participants reported a frequent or always use of extra coronal restoration in the tooth with treated by post and core. Composite resin (71%) was preferred for the core foundation, followed by glass ionomer (23%) among the general dentists. Com posite resins were the core build-up material of choice (71%), followed by glass ionomer (23%). Amalgam was rarely used (3%) among the general dentists. Within the limitations of the present study, there were differences in practices followed in the restoration of ETT among the different spe cialties and general practitioners studied in Tripoli, Libya.
