Evaluation of Dental Anxiety in Second-Stage Implant Surgery With Er,Cr:YSGG Laser

Study Overview
=================
Brief Summary
-----------------
Implants embedded under the oral mucosa were exposed with scalpel (Group 1) or laser surgery (Group 2). Before the operation the patients were asked to fill the State-Trait Anxiety Inventory (STAI) and Dental Anxiety Scale (DAS) while resting in the waiting room.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dental anxiety | Before the operation the patients were asked to fill the State-Trait Anxiety Inventory (STAI) questionary.Patients' answers to each question were scored between 1-4 points. A total of 20-37 anxiety scores were assessed as minimum level of anxiety or none, 38-44 points as moderate and 45-80 as high. | 20 minutes before the operation | 
| Dental Anxiety | Before the operation the patients were asked to fill the Dental Anxiety Scale (DAS). Patients' answers to questions were scored between 1-4 points. The total score of the questions in the questionnaire ranged from 4 to 20, and 4-11 points were interpreted as low level dental anxiety, 12-14 points as moderate and more than 14 points as high. | 20 minutes before the operation |
