Conditions

Impacted Third Molar Tooth

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.

Interventions

Inclusion criteria

* ASA I-II * Aged 18-35 * Symmetrical Class 2 Position B according to Winter and Pell-gregory classification * Asymptomatic lower third molar tooth with the same difficulty according to the Yuasa difficulty index

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
Change in Oral Health-related Quality of LifeTime Frame: 14 daysEvaluated 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

MeasureTime frameDescription
Change in pain7 daysPostoperative pain was assessed using a Visual Analogue Scale (VAS) ranging from the absence of pain (score 0) to the most severe pain imaginable
Change in Mouth opening7 daysThe 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 timeIntraoperativeThe 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 swelling7 daysWith 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.
