Vital pulp preservation treatment in mandibular right first molar with vertical root fractures: a case report

doi:10.7518/hxkq.2019.05.021

Abstract

Abstract:

This case presents vertical root fracture with vital pulp in mandibular right first molar. Examinations of the history, clinical tests, laser Doppler flowmetry, and radiographs revealed that the tooth showed positive response to electric pulp testing and was normal compared with the healthy control tooth. This study aimed to use a novel vital preserving surgical technique (microapical surgery and nanometer bioactive materials) to make an effective therapeutic decision for the vital tooth with vertical root fracture.

Key words: vertical root fracture, microapical surgery, vital pulp preservation, mandibular first molar
