Nonsurgical management of complex endodontic cases with several periapical lesions: a case series

Aim: Today, thanks to modern technologies as operative microscope, ultrasonic tips, devices to activate irrigation and tridimensional obturation performed with thermo plasticized guttapercha, excellent results could be obtained. Materials and methods: In this study, we present 5 patients with the presence of periapical lesions in molars and incisors with history of pain. Modern endodontic technologies were used. The rationale of using these technologies was to obtain a chemo-mechanical cleansing and obturation of the entire endodontic system and to gain the lesion resolution with a non-surgical approach. Results: A success rate of 100% was obtained. Radiographs and clinical examinations were done until 10 years. All the cases highlighted the success achieved in the short and long term through the complete resolution of the lesions and therefore the reconstitution of the lamina dura. Conclusions: The positive results highlighted by these clinical cases demonstrate how the use of modern technologies is essential to avoid iatrogenic damage and to gain safe and reproducible results.
