Objectives: To compare the effects of diode and erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) lasers in second-stage implant surgery applications. Methods: This is a cross-sectional study that was carried out on patients who received implant treatment at the Departments of Oral and Maxillofacial Surgery and Periodontology, Van Yuzuncu Yil University, Van, Turkey between January 2017 and January 2018. Implants of the patients in the first group (n=20) were exposed with 940 nm Ga-Al-As diode laser while the implants of the second group (n=20) were uncovered with 2780 nm Er,Cr:YSGG laser in the second-stage surgery. Visual analogue scale (VAS) values during day 0 and following the operation on days 1, 2, 3 intraoperative bleeding grades, number of analgesics used in the postoperative period, operation time per implant, and postoperative complications were recorded. Results: When gender, smoking, the presence of systemic disease, toothbrushing frequency, analgesic use, bleeding and complications observed at the control session were analyzed, no statistically significant relationship was found between the 2 groups. It was observed that males had statistically significant higher VAS values than females ( p <0.05). Conclusion: Since diode lasers are more economical, smaller, and can meet the clinical needs of clinicians, it is likely that these lasers may be the preferred choice of the clinicians in surgical procedures.

Oral surgical procedures cause high-pain expectation and consequent anxiety in patients. The aim of this study is to compare the effects of Er, Cr: YSGG laser and scalpel method on dental anxiety level during second-stage implant surgery. 96 patients with 304 osseointegrated implants were divided into two groups. Implants embedded under the oral mucosa were exposed with scalpel or laser surgery. Before the operation the patients were asked to fill the STAI and DAS while resting in the waiting room. In addition, postoperative daily analgesic use, VAS scores perioperativly and on the postoperative 1 st , 2 nd and 3 rd days and demographic information such as age and gender were also recorded. There was no statistically significant relationship between surgical m ethod and anxiety levels (p>0.05. Also, the differences between the scalpel and laser groups in terms of total DAS and STAI scores were statistically insignificant (p>0.05). But statistically significant difference was found between surgical method and the analgesic consumption (p<0.05). A higher rate of analgesic consumption was observed in the scalpel group. The use of Er,Cr;YSGG laser could reduce pain during minor oral surgical procedures but had no significant effect on dental anxiety. Different modalities that could provide additional benefits in overcoming this situation should be investigated.
