A research study conducted at Prince Sattam Bin Abdul Aziz University examined the factors that affect the success of endodontic retreatment procedures. The study analyzed 250 cases of endodontic retreatment and collected demographic and clinical data. The researchers found that factors such as rotary instrumentation, gutta-percha obturation, and the use of intracanal medication were significantly associated with higher retreatment success rates. The study concluded that understanding and optimizing these factors are important for improving treatment outcomes and patient satisfaction.

A recent study conducted at King Khalid University examined the factors that influence the success of endodontic retreatment techniques. The study analyzed 500 patient records over a 5-year period and documented pre-operative factors, procedure specifics, post-operative results, and demographic information. The results showed that age, initial diagnosis, and root canal morphology were significant indicators of retreatment success. The researchers concluded that individualized treatment techniques based on each patient's unique features can enhance endodontic retreatment success rates and improve patient care.

A recent study conducted by researchers from the Department of Conservative Dentistry and Endodontics explores the influence of heat-treated files on conserving the remaining dentin thickness during endodontic retreatment. The study compared two different rotary instruments, ProTaper retreatment files (PTR) and Solite RS3 (S-RS3) Retreatment files, and used Cone Beam Computed Tomography (CBCT) to assess the remaining dentin thickness after gutta-percha retrieval at different levels. The results showed that Solite RS3 files preserved more dentin thickness on the mesial side compared to ProTaper retreatment files. However, the study acknowledges the need for further research to arrive at a definitive conclusion. [Extracted from the article]

A recent study conducted by researchers at Vilnius University in Lithuania explored the use of citric acid as a solvent for hydraulic calcium silicate-based (HCS) sealers in endodontic retreatment procedures. The study found that 10% and 20% citric acid solutions were effective in dissolving HCS sealers without causing significant damage to root dentin. The researchers observed intense gas release during the interaction of HCS materials and citric acid, indicating its potential as a solvent. These findings suggest that citric acid could be a viable option for HCS sealers in endodontic retreatment procedures. [Extracted from the article]

A recent study conducted at Imam Abdulrahman Bin Faisal University in Saudi Arabia compared the softening effect of three gutta-percha solvents on different types of gutta-percha with different application durations. Gutta-percha solvents are commonly used in non-surgical endodontic retreatment to aid in the removal of gutta-percha. The study found that the softening effect of the solvents varied depending on the type of solvent, application duration, and type of gutta-percha. The results highlight the importance of considering these factors when selecting a solvent for endodontic retreatment. [Extracted from the article]

A recent study conducted at Himachal Dental College in India explores a method for reinforcing and restoring damaged teeth that have already received endodontic treatment and have an existing crown. The research emphasizes the importance of preserving dental components during endodontic retreatment and highlights the advancements in endodontic procedures and materials that have reduced the need for surgical treatment. The study outlines a technique that involves rescuing the undamaged crown, re-cementing a damaged post in the canal, and using a dual-cured composite resin to rebuild the core and re-cement the crown. The method was found to be effective in strengthening the tooth's core and restoring it with the existing crown, even after a year of follow-up. [Extracted from the article]

A patent was issued for an endodontic system and instrument designed for the irrigation and disinfection of a tooth root canal. The system aims to thoroughly clean all aspects of the root canal system to prevent post-treatment failures and bacterial leakage. The instrument includes a flexible core with radial protrusions and longitudinal grooves, allowing for effective cleaning and disinfection of the root canal. The system also incorporates light excitation sources for visual enhancement and wavelengths used in photo-dynamic therapy. [Extracted from the article]

Researchers at University Gadjah Mada in Yogyakarta, Indonesia have conducted a study on endodontic mishaps in dentistry, such as missed canals and broken files, which can affect the success of root canal treatment. The researchers found that an ultrasonic instrument, used under a dental microscope, can effectively manage missed canals and broken file fragments. They presented a case study of a 31-year-old female patient who underwent retreatment using this technique, which involved removing gutta-percha, exploring missed canals, retrieving the broken file, and preparing the root canals. The study concluded that an ultrasonic device, along with a dental microscope, can conservatively manage missed canals and instrument separation. [Extracted from the article]

A recent study conducted by the University Center for Dental Medicine Basel UZB in Switzerland aimed to assess the amount of erosion during activated endodontic irrigation using two different chelating agents, HEDP and EDTA. The study found that HEDP had a significantly less erosive effect compared to EDTA. The researchers used high-resolution micro-computed tomography to measure erosion depth and found significant differences between the two chelating agents. This study provides valuable insights for dentistry and suggests that different irrigation protocols could be assessed using micro-CT. [Extracted from the article]

Central to a successful endodontic treatment has been the use of chemical reagents during mechanical root canal shaping procedures to completely clean all aspects of the root canal system. However, if the smear layer or film is not adequately removed from the root canal, the smear layer can compromise the filling and sealing of the root canal system. The chemicals used to enhance canal debridement and disinfection during cleaning and shaping procedures potentially reach all aspects of the root canal system.

Dentine mud, pulp, bacteria, and other related irritants have been consistently visualized histologically after cleaning and shaping procedures in the dentinal tubules and various aspects of the root canal systems. However, if the smear layer or film is not adequately removed from the root canal, the smear layer can compromise the filling and sealing of the root canal system. Central to a successful endodontic treatment has been the use of chemical reagents during mechanical root canal shaping procedures to completely clean all aspects of the root canal system.
