laser_case report tion.19, 38 Then, to achieve its maximum bactericidal properties, the Er,Cr:YSGG laser should work on a dry canal, allowing the energy to be transmitted deep into the dentinal tubules22 and to instantaneously interact with the water molecules trapped into the bacterial membrane and within endodontic bio- films.39 RFT have been shown to overcome several limita- tions attributed to bare fibres, distributing the emit- ted laser energy in a uniform ring-shaped pattern.33, 59 In similarity with any other innovative root canal treatment strategies, there are few reports demon- strating the prospective, long-term clinical out- comes associated with the use of Er,Cr:YSGG laser, namely with RFT. However, Martins et al. have shown that RFT can be considered predictable as the con- comitant use of 3 % NaOCl and CH for the endodon- tic treatment of single-rooted teeth with apical peri- odontitis.42, 43 Our findings may provide further evidence that RFT can be considered safe in cases of teeth with wide apical foramina while being ade- quate to effectively reach all the contours of the re- sorption lesion. The prognosis for the conservative treatment of IRR should increase due to the report of alternative endodontic techniques along with the use of new technologies (Al-Momani & Nixon 2013, Khojaste- pour et al. 2015, Nilsson et al. 2013).2, 44, 46 Therefore, clinicians may consider this laser-assisted technique while selecting an appropriate endodontic disinfec- tion strategy for the management of IRR. Conclusion Despite their intrinsic methodological limitations, the adequate report of single clinical cases may either help the understanding of unusual presentations of common diseases or assist in guiding new treatment concepts into clinical practice.45 This case report pres- ents potential benefits towards the use of Er,Cr:YSGG laser and radial firing tips in endodontics. Further ran- domised clinical trials should be conducted to clearly demonstrate its effectiveness._ Editorial note: A list of references is available from the publisher. contact Dr Miguel Rodrigues Martins, DDS, MSc, PhD Endodontic Department, Faculty of Dental Medicine, Universidade do Porto, Portugal Rua Dr. Manuel Pereira da Silva, 4200-393 Porto, Portugal Tel.: +351 914610046 miguel.ar.martins@gmail.com Essential Dental Media Dental Tribune International The World’s Largest News and Educational Network in Dentistry 38 1_2017 38 laser www.dental-tribune.com
