Study summary

This single-center prospective cohort study includes patients aged 18-30 years aimed to compare the effects of bilateral extraction of wisdom teeth at a single appointment (Group A) versus two separate appointments (Group B) on patients' oral health-related quality of life (OHRQoL). The primary outcome is Oral Health Impact Profile 14 score, while secondary outcomes included postoperative pain and maximum interincisal opening.

Interventions

  • ProcedureSingle-Session Bilateral Mandibular Third Molar Extraction

    Participants in this group chose to have both of their lower mandibular third molars extracted during a single appointment. This group will be used to compare the impact of single-session extraction on patients' oral health-related quality of life, postoperative pain, and maximum interincisal opening.

  • ProcedureTwo-Session Bilateral Mandibular Third Molar Extraction

    Participants in this group chose to have their lower mandibular third molars extracted during two separate appointments. This group will be used to compare the impact of two-session extraction on patients' oral health-related quality of life, postoperative pain, and maximum interincisal opening.

What researchers measure

Primary outcomes

  1. Change from baseline oral health-related quality of life at 14 days

    The Oral Health Impact Profile-14 (OHIP-14) questionnaire is used to evaluate the participants' oral health-related quality of life. The OHIP-14 is a validated instrument that assesses the perceived impact of oral conditions on an individual's well-being across 14 items, each scored on a 5-point Likert scale. Lower scores indicate better OHRQoL.

    Time frame: Baseline, postoperative day 2, day 3, day 7, day 9, and day 14

Secondary outcomes

  1. Change from baseline postoperative pain at 14 days

    The Visual Analog Scale (VAS) is used to assess the intensity of postoperative pain experienced by participants. The VAS is a validated tool consisting of a horizontal or vertical line, usually 100 mm in length, with anchor points of "no pain" at one end and "worst imaginable pain" at the other. Participants are asked to mark the point on the line that corresponds to their pain level. Higher scores indicate greater pain intensity.

    Time frame: Postoperative 6th hour, 12th hour, day 2, day 3, day 7, day 9, and day 14

  2. Change in maximum interincisal opening

    Maximum interincisal opening (MIO) is being measured to evaluate trismus, or restricted mouth opening, following the extraction of mandibular third molars. MIO measurements are taken using a ruler to measure the distance between the upper and lower central incisors when the participant opens their mouth as wide as possible. Lower values indicate greater trismus.

    Time frame: Baseline and postoperative day 7
