简要总结
The aim of this study was to compare the Antibacterial Efficacy of Diode Laser 810nm and Photodynamic therapy in reducing bacterial microflora in endodontic retreatment of teeth with periradicular lesion.
详细描述
Conventional techniques of root canal treatments such as mechanical instrumentation and chemical debridement with antimicrobial irrigants, such as Sodium hypochlorite (NaOCl) and chlorhexidine and use of calcium hydroxide do not always suffice to predictably render root canals free of bacteria Using the high-power diode laser is a new approach of disinfection allowing access to the previously unavailable areas, such as the tubular network. This study, therefore, compares two types of diode lasers (low-power and high power) in terms of anti-bacterial effect as well as the conventional endodontic retreatment to determine the ideal method of root canal disinfection.
