Chapter 6110given verbal and written postoperative instructions, and they were recalled for follow-up at 1 week.Follow-upOne week after surgery, patients were examined to assess surgical site wound healing and to check for alveolitis and wound infection. At that time, the completed OHIP-14 questionnaires were collected. Outcome measurementsThe outcome measurements included the OHIP-14 score, the pain score, based on the numeric rating scale (NRS) and the daily analgesic intake. OHRQoL was assessed with the OHIP-14 questionnaire. It involved the following parameters: problems pronouncing words, altered sense of taste, difficulty in chewing, pain/aching, worry about dental problems, psychological discomfort, problems affecting the diet, interruptions in meals, difficulty relaxing, feeling embarrassed, feeling irritable, job-related difficulties, less satisfaction in life, and functional inabilities. The short form of the OHIP-14 consisted of 14 items within 7 domains, including: functional limitations, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicaps.15-16 Patients rated each item on a 5-point scale, with 4=very often, 3=fairly often, 2= sometimes, 1=hardly ever, and 0=never. The total score ranged from 0 (minimum impact) to 56 (maximum impact). Scoring high on the OHIP-14 questionnaire indicated that the surgery had a strong impact on the OHRQoL. Pain assessment was measured by rating pain intensity with an 11-point NRS, which ranged from 0 (no pain) to 10 (worst possible pain). Patients self-rated their pain on each day of the first postoperative week.14-16 The questionnaires were completed daily at the end of the day.At the 1-week control visit, an independent assessor evaluated wound infection, alveolitis, and the sensory function of the IAN. The patients were assessed for sensory disorders, such as pain, numbness, dysesthesia, or paresthesia, based on a 2-point discrimination and static light touch detection test.3Data managementAll patient data on infection, alveolitis, analgesic intake, pain scores and OHIP14 scores were collected between January 2019 and December 2019 and
