Healing of Apical Periodontitis after Minimally Invasive Endodontics therapy using Er,Cr:YSGG laser: A Prospective Clinical Study
Systematic Review Pharmacy, 2020;11(2):6
Abstract
The aim of the present study was to clarify the healing percentages for a 6-months duration after clinical endodontic treatment, in cases treated by Er,Cr:YSGG laser (Waterlase MD; Biolase Technology, Inc, San Clement, CA) and filled by two obturation techniques. The study group were composed of 40 patients, who were referred for endodontic treatment and diagnosed having apical periodontitis. They received minimally invasive nonsurgical root canal treatment with ProTaper Next instruments and copious irrigation with 5% NaOCl. After instrumentation, laser irradiation was performed for smear layer removal with Er,Cr:YSGG laser 2,780 nm wavelength with radial firing tips RFT2 and RFT3. After laser irradiation, a final irrigation was done with 5ml of saline solution, then disinfection for the root canal was done with the same laser device. The subjects were divided into 2 groups; the first one was obturated with carrier-based technique (GuttaCore) and the other with cold lateral compaction technique, AH Plus sealer was used in both groups. Healing of the different apical periodontitis cases was evaluated clinically and radiographically employing Periapical index (PAI) scoring. Forty patients were followed up at three recall periods at 1-month, 3-month, and 6-month after treatment. The success of root canal treatment for these periods was 67.5%, 82.5%, and 97.5%, respectively. In conclusion, the teeth of different apical diagnosis can be treated with the Er,Cr:YSGG laser. It showed a tremendous degree of success of root canal treatment in a period of 6 months after treatment. The Er,Cr:YSGG laser permits rapid rate of healing with a predictable outcome.
