According to the survey of Qualtrough et al. [19], cold lateral condensation has been the most popular undergraduate selleckchem root-filling technique. However, in our study, using gutta-percha with sealer without lateral condensation was favoured by most of the respondents (55.3%), followed by cold lateral condensation (33.8%). Using gutta-percha in conjunction with a sealer is a relatively simple and versatile technique that does not require expensive equipment [12]. This might be the reason why this technique is used by the majority of responding practitioners in their general practice. The finding for the cold lateral condensation method is relatively lower than the findings of Palmer et al. [7] (75%) and Al-Omari [9] (46.6%).

While some dentists are using techniques taught during their undergraduate education, there are a number of dentists using techniques with no evidence of clinical effectiveness that they were not taught in their undergraduate course [7, 12]. Although single-point technique is not being taught nor recommended in dental schools, it has been used by 26.8% of all respondents. Its simplicity might be the reason for its frequent use. Similarly, paste-only root fillings are difficult to control with the risk of under- or overfilling of the canal [12], but 3.2% of respondents used only paste to obturate the root canal system. Though warm gutta-percha filling techniques are not taught in the majority of dental schools in Turkey, it’s been used by 3.5% of the respondents of all age groups. This finding shows that a number of practitioners made an effort to use filling techniques other than those taught in undergraduate education.

The most popular root-canal sealer amongst Turkish GDPs was AH Plus, followed by Endomethasone. This finding is in accordance with the findings of Hommez et al. [17] and in contrast with the findings of Jenkins et al. [12], Ahmed et al. [8], and Al-Omari [9], who found that the majority of the respondents used zinc-oxide-based sealers. These differences are likely to be attributed to different materials and methods used in dental training between universities [19].According to the ESE quality guidelines for endodontics [1], the tooth should be adequately restored to prevent bacterial recontamination of the root canal system or fracture of the tooth. In the present survey, adhesive restoration was the choice of final restoration and resin composite was the material of choice. The use of a crown or an inlay/onlay restoration was relatively lower compared to the findings of Palmer et al. [7]. Economic considerations might be the reason most of the practitioners choose relatively cheaper resin composite Brefeldin_A restorations instead of crown or inlay/onlay restorations.
