Conclusion
Treatment of dilacerated root canals, especially teeth with difficult anatomy requires an integration of an accurate diagnostic armamentarium, novel techniques, and modern instrumentation. Furthermore, complementary achievements in the area of activation of ultrasonic irrigation and thermoplasticized warm vertical obturation have enabled better cleaning and obturation of curved canals by minimal residual infection, which leads to long-term clinical outcomes. This paper reports on three complex endodontic cases that encourage the dental profession to treat even the most challenging anatomical situations. These variations can affect technique effectiveness, so future studies with larger and more diverse samples, including various tooth types and canal configurations, and with longer follow-ups, can demonstrate long-term outcomes of treatment efficacy. Future investigations and new technologies will assist clinicians in refining existing and developing new methods to better care for patients and effectively treat challenging cases, such as those with dilacerated roots.
