Post-Surgical Morbidity and Bone Healing of Impacted Lower Third Molars: Piezosurgery vs. Conventional Instruments

Not Applicable

Completed

• Conditions: Impacted Third Molar Tooth
• Interventions: Device: Conventional burs; Device: Piezosurgery

• Registration Number: NCT06262841
• Lead Sponsor: Ankara University

Brief Summary

The aim of this study is to compare piezosurgery and conventional surgery in impacted third molar surgery and to determine its effect on postoperative outcomes and quality of life.

Detailed Description

The aim of our study is to comparatively evaluate the duration of the operation and the pain, trismus, edema and healing of the alveolar bone that occur after tooth extraction in surgical extractions of impacted lower third molar teeth using piezosurgery and traditional rotary instruments.

Arm && Interventions

Group	Intervention	Description
Conventional group	Conventional burs	In the control group, conventional burs were used to remove the bone surrounding the impacted third molar. Intervention: Device: Conventional burs
Piezosurgery group	Piezosurgery	In the experimental group, a piezosurgery device was used to remove the bone surrounding the impacted third molar. Intervention: Device: Piezosurgery

Primary Outcome Measures

Name	Time	Method
Change in Oral Health-related Quality of Life	Time Frame: 14 days	Evaluated by Oral Health Impact Profile-14 questionnaire (OHIP-14). The OHIP-14 scores can range from 0 to 56 and are calculated by summing the ordinal values for the 14 items. The domain scores can range from 0 to 8. Higher OHIP-14 scores indicate worse and lower scores indicate better Oral Health Related Quality of Life.

Secondary Outcome Measures

Name	Time	Method
Change in Mouth opening	7 days	The distance between the mesio-incisal corners of the upper and lower central incisors was measured with the help of a ruler when the mouth opening was at its maximum.
Operation time	Intraoperative	The total time from the first incision of the operation site to the last suture was measured with the help of a digital stopwatch as the operation time.
Change in facial swelling	7 days	With the technique described by Neupert ; Angle of mandible-tragus Angle of mandible-lateral canthus of eye Mandible corner-nose wing Angle of mandible oral-commissures Measurements were made with a tape measure from 5 points, with the mandible corner-pogonion.
Change in pain	7 days	Postoperative pain was assessed using a Visual Analogue Scale (VAS) ranging from the absence of pain (score 0) to the most severe pain imaginable
