An evidence-based assessment of the clinical guidelines for replanted avulsed teeth. Part I: timing of pulp extirpation

Abstract

BACKGROUND: Clinical guidelines for the management of avulsed teeth recommend pulp extirpation (PE) within 10 to 14 days of replantation. The principles of evidence-based dentistry can be used to assess whether this is the best approach based on currently-available evidence. The objective of this study was to use the principles of evidence-based dentistry to answer the PICO Question: (P) For a replanted avulsed permanent tooth, (I) is early PE within 10 to 14 days of replantation, (C) compared with delayed pulp extirpation, (O) associated with an increased likelihood of successful periodontal healing after tooth replantation? MATERIALS AND METHODS: A literature search was performed across fo..
