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

Overview

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.

Full Title of Study: “Evaluation of Dental Anxiety in Patients Undergoing Second Stage Surgery With Er,Cr:YSGG Laser Treatment: Randomized Clinical Trial”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Double (Participant, Investigator)
  • Study Primary Completion Date: July 10, 2018

Interventions

  • Procedure: Scalpel
    • 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.
  • Device: 2780 nm Er,Cr:YSGG Laser
    • Exposure of the cover screw of osseointegrated dental implants embedded under oral mucosa by performing the soft tissue incision with erbium laser for placing the healing abutment.

Arms, Groups and Cohorts

  • Active Comparator: Scalpel
    • Soft tissue incision with scalpel in second- stage implant surgery.
  • Experimental: Erbium laser
    • Soft tissue incision with 2780 nm Er,Cr:YSGG laser, at implant recovery settings (2.00 W power, 100 Hz H mode, 10% water and 10% air) in second-stage implant surgery.

Clinical Trial Outcome Measures

Primary Measures

  • Dental anxiety
    • Time Frame: 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
    • Time Frame: 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.
