Root canal retreatment is carried out in cases where previous endodontic therapies failed and involves the removal of root canal filling materials, followed by cleaning, shaping, and obturating of the canals.
: The objective of this study was to collect information regarding attitudes, methods, and materials employed during the non-surgical endodontic retreatment (NSER) by general dentists working in Sousse Governorate, Tunisia.
A descriptive cross-sectional survey was conducted among 147 general dentists working in the Sousse Governorate, Tunisia, from May to November 2021. Data were collected by sending a structured questionnaire to the dental practitioners through email. All the data were analyzed by using the SPSS 10 computer software.
A total of 96 dentists responded to this survey. The response rate was 63.5%, with a female predominance (53.2.3%). 81.2% of the respondents performed at least one non-surgical endodontic retreatment (NSER) weekly. Our study revealed that the mandibular first molar is the tooth that most often requires endodontic retreatment (83.5%). Half of the participants never used the rubber dam during this procedure. Moreover, the majority of respondents (61.9%) simultaneously used manual files and rotary nickel-titanium instruments for root canal desobturation. Most of the dentists (69.57%) systematically use solvents during root canal desobturation.
Our survey highlights that the majority of general dentists have adequate knowledge about endodontic retreatment. Nevertheless, dentists are yet to start the application of these newer strategies towards the management of endodontic failures.
根管再治疗适用于先前牙髓治疗失败的病例，包括去除根管充填材料，随后进行根管清理、塑形和充填。
本研究的目的是收集有关突尼斯苏塞省普通牙医在非手术牙髓再治疗（NSER）过程中所采用的态度、方法和材料的信息。
2021年5月至11月，对突尼斯苏塞省的147名普通牙医进行了描述性横断面调查。通过电子邮件向牙科从业者发送结构化问卷来收集数据。所有数据均使用SPSS 10计算机软件进行分析。
共有96名牙医回复了此次调查。回复率为63.5%，女性占多数（53.2%）。81.2%的受访者每周至少进行一次非手术牙髓再治疗（NSER）。我们的研究表明，下颌第一磨牙是最常需要进行牙髓再治疗的牙齿（83.5%）。一半的参与者在这个过程中从未使用橡皮障。此外，大多数受访者（61.9%）在根管去充填时同时使用手动锉和旋转镍钛器械。大多数牙医（69.57%）在根管去充填时系统地使用溶剂。
我们的调查强调，大多数普通牙医对牙髓再治疗有足够的了解。然而，牙医们尚未开始将这些新策略应用于牙髓治疗失败的管理。
