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.

Interventions

PROCEDUREScalpel

Exposure of the cover screw of osseointegrated dental implants embedded under oral mucosa by performing the soft tissue incision with scalpel for placing the healing abutment.

Design outcomes

Primary

Measure	Time frame	Description
Dental anxiety	20 minutes before the operation	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.
Dental Anxiety	20 minutes before the operation	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.
