Comparison of quality of life after surgical endodontic treatment using two techniques: A prospective study

Objective. The purpose of this prospective study was to compare patient experience of quality of life following surgical endodontic treatment using 2 different techniques: a technique that included the use of a dental operating microscope, root resection with minimal bevel and retrograde preparation with ultrasonic tips, and a traditional technique that included root resection with a 45°bevel and retrograde preparation by bur performed without magnification. Study design. The study consisted of 66 patients referred for surgical endodontic treatment. One operator (I.T.) carried out all treatment. An equal number of patients were assigned to each group. Group 1 was treated by the traditional technique without an operating microscope and Group 2 by a technique using an operating microscope and minimal osteotomy. All patients were given a questionnaire with 15 questions to evaluate their quality of life for 7 days postsurgery. Results. On day 5, patients in Group 1 reported significantly more pain and took significantly more analgesics (P <. 05). On days 1 and 2, patients in Group 2 reported significantly more difficulty in mouth opening, mastication, and the ability to speak (P <. 05). Conclusion. Patients in both groups reported a high incidence of symptoms. The technique using the operating microscope provided significantly less postoperative pain, but more difficulties in mouth opening, mastication, and the ability to speak immediately postoperatively.
