research | 21 1 2016 laser Er,Cr:YSGG laser is a safe instrument with a high level of tissue adaptive capability; compared to con- ventional drills used for preparation of the bone bed of the implant, application of this instrument results in a much smaller temperature raise in the tissue, which is within the tolerance range of the tissue.19 It seems that the application of this particular type of laser imposes mitochondrial osteoblastic function with no significant impact;20 in other words, the os- teoblastic function necessary for bone formation around the implant area is preserved using this method. Additionally, according to the findings of Secilmis et al., using power configurations of 1 and 2 Watts imposes minerals of hard tissue with not significantly change and superficial strength, con- nectivity capability is not reduced.21 Additionally, histo-pathological evaluations indicate that various radiations of this laser with lesser powers do not trigger inflammatory response; the application of laser radiation does not elevate inflammatory re- sponse to ranges that affect the tissue healing pro- cess with negative effects.22 Few studies are con- ducted on disinfection capabilities of Er,Cr:YSGG laser. Ishizaka et al. found that lower power used in Er,Cr:YSGG laser radiation preserved the smear layer removal performance. In their study, all three power configurations of 1, 3 and 5 Watts removed the smear layer properly; also, the performance was related to the diameter of the tip of the fibre and flatter tips proved to be more efficient in disinfec- tion.23 Yamakazi et al. did not find significant differ- ences in the smear layer removal performance using power configurations of 1 to 6 Watts; however, in contrast to dry radiation, cooling the target at the time of radiation resulted in better performance of smear layer removal.24 Microorganisms are an important part of the smear layer that may have a specific role in reduc- ing the success rate of dental implants. Several studies were focussed on the bactericidal effects of the Er,Cr:YSGG laser radiation. Generally, these studies did not focus on different settings of laser radiation, bur investigated tooth root canal and implant surface. Moreover, specific germs that par- ticipate in implant infection are similar to oral microbial flora and pathogens.24,26 Gordon et al. studied 15 settings of Er,Cr:YSGG laser (175 to 325 mW and exposure times of 15 to 340 seconds) and their results were compared to the results of Faxantwort an 034148474-290 Name/Vorname Straße PLZ/Ort Telefon/Fax E-Mail Datum/Unterschrift Praxisstempel laser 1/16 49€* * Preis versteht sich zzgl.
