Success rate of endodontics instrument retrieval using magnification devices
A systematic review and meta analysis
Keywords:
magnification, apicoectomy, surgical endodontics, loupes, endoscopic devicesAbstract
Retrieval of the broken instrument in the root canal is critical for the endodontic success. Hence in the present study we aimed to conduct a systematic review and meta-analysis to assess the success of the endodontics instrument retrieval using magnification devices. We piloted a prospective clinical trial comparing endodontic therapy performed with or without using magnification devices that was based on the clinical and radiographic estimation after a year of follow-up. The key terms searched were: “endodontic treatment, endodontic therapy, endodontic surgery, apicoectomy, periapical surgery, microscope, endoscope, loupes, magnification devices”. The sources searched were “MEDLINE, Embase, Cochrane Oral Health Specialized Register, Cochrane Central Register of Controlled Trials”, the period of searched was from September 2009 to 2021. Statistical analysis was performed using the software Review Manager. Of 470 studies only 3 studies were finalized. No significant variation in outcomes was found among patients treated using magnifying devices. Correspondingly, no variation was found with or without using the endoscope. No comparative study on magnification devices was found regarding orthograde endodontic treatment. The efficiency of the dentist is the key factor in the retrieval of the broken instrument, rather than the magnification devices.
