Patient questionnaire
NRS, pain
The postoperative follow-up and evaluation of the cases were performed by a researcher who had no knowledge of the study groups.A 10-point numerical rating scale (NRS) was introduced to the patients, and they were asked to rate their post-treatment pain by telephone after 12, 24, 48, and 72 h.The antibiotics and analgesics usage were questioned.The patients were appointed for the clinical examination 1 week later.Palpation and percussion sensitivity in the treated teeth was determined on the basis of the patients’ perceptions of pain. All percussion tests were performed by the same operator to ensure standardization.The measurement values were based on the 10-point NRS. The pain scores were placed into the following four categories: 0 = none, 1–3 = mild, 4–6 = moderate, and 7–10 = severe.
