EFFECT OF THE TYPE OF THE ANESTHETIC SOLUTION ON THE INCIDENCE OF PULP NECROSIS FOLLOWING CROWN PREPARATION: A RANDOMIZED CLINICAL STUDY

Abstract Objective: The objective of the present study was to evaluate the effect of the type of the anesthetic solution (with or without epinephrine) on the development of pulp necrosis after tooth preparation. Methods: Seventy-two patients were randomly allocated into 2 groups according to the type of the anesthetic solution used. In the first group, 4% articaine with 1:100.000 epinephrine was used as local anesthesia and in the second group, 3% plain mepivacaine was used. Before administration of the anesthetic solution, electric pulp tester (EPT) and cold test were used to test the vitality of the teeth. The teeth were then prepared and provisional crowns were fabricated chairside. After 15 days, the provisional crowns were removed and then the EPT procedures and cold test were repeated. Postoperative pain level on days 1, 3, 5 and 15 were recorded. The EPT scores and pain levels were statistically analyzed. Results: A statistically significant difference was observed between the groups in terms of percentage change in EPT scores. Conclusion: The type of the anesthetic solution does not affect the vitality of the teeth after full-crown preparation. Keywords: Anesthetic solution, pulp necrosis, Articaine, Mepivacaine     Kuron Preparasyonunu Takiben Görülen Pulpa Nekrozuna Anestezi Solüsyonu Tipinin Etkisi: Bir Randomize Klinik Çalişma Öz Amaç: Bu çalışmanın amacı, diş preparasyonu sonrası gelişen pulpa nekrozu üzerine kullanılan anestezi solüsyonunun etkisini değerlendirmektir. Metod: 72 hasta kullanılacak anestezi solüsyonu tipine göre rastgele olarak 2 gruba ayrıldı. Birinci grupta lokal anestezi olarak 1/100000 epinefrinli %4’lük articaine kullanıldı ve ikinci grupta %3 sade mepivacaine kullanıldı. Anestez uygulamasından önce elektrikli pulpa testi (EPT) ve soğuk testi kullanılarak dişlerin vitalitesi test edildi. Daha sonar diş preparasyonu yapıldı ve geçici kuronlar uygulandı. 15 gün sonar geçici kuronlar söküldü ve EPT ve soğuk testi prosedürleri tekrarlandı. Tedaviden sonraki 1., 3., 5. ve 15. günlerde ki postoperative ağrı değerleri kaydedildi. EPT değerleri ve ağrı skorları istatistiksel olarak analiz edildi. Bulgular: Gruplar arasında EPT yüzdelik değişimleri açısından istatistiksel olarak anlamlı farklılık olduğu gözlemlendi. Sonuç: Kullanılan anestezi solüsyonu tipi, tam kuron preparasyonu sonrası dişlerin canlılığını etkilememektedir. Anahtar kelimeler: Anestezi solüsyonu, pulpa nekrozu, Articaine, Mepivacaine
