Abstract
Non-surgical endodontic retreatment is generally the preferred method for managing post-treatment disease. Its success rate is considered favourable especially with the introduction of advanced techniques and materials. However, treatment planning and practices may vary between specialists and general practitioners, influenced by their educational background, clinical experience, attitudes, and available resources. The aim of this study was to gather information on the awareness, attitudes, techniques, and materials used in non-surgical endodontic retreatment (NSER) among Libyan dentists. A questionnaire related to endodontic retreatment was distributed randomly via various social media platforms. The survey was structured into two sections: the first part: which included demographic details, and the second part: which consisted of a series of questions designed to assess the trends, techniques, materials, and opinion of dentists regarding endodontic retreatment. Data was gathered and statistically analyzed using SPSS version 25. Descriptive statistics were calculated to determine frequencies and percentages for each survey item. Additionally, chi-square tests were conducted to identify significant differences in practices based on speciality and other demographic factors. Out of 102 respondents, 16% were en-dodontists (ENs), 63% were general practitioners (GDs) and 21% were dentists from other speciality with a female predominance (79%). Persistent infection was reported as the most common cause of failed endodontic treatment. Most dentists felt that managing complications such as perforations and ledges is the most challenges face of retreatment. The most significant finding was in rubber dam usage among the dental specialties with p-value of (P = 0.002). Almost all practitioners apply both hand and rotary files for removal of old fillings. Respectively, sodium hypochlorite and calcium hydroxide were the preferred choices for irrigation and intracanal medicament. However, ENs utilize higher concentration of sodium hypochlorite. Cold lateral compaction technique was the most commonly used method for obturation. In conclusion: it has been found that although there are some variations in the trends of endodontic re-treatment practices between Endodontists (ENs) and other dentists, it can be asserted that Libyan general dentists, endodontists, and dentists from other specialties demonstrate a sufficient level of awareness and adhere to similar protocols in managing retreatment cases.
