The idea of moving a small instrument through the apical constriction with the intention of preventing debris accumulation and canal blockage during root canal instrumentation, as well as disrupting bacterial biofilms in the foraminal area, has gained increasing popularity among clinicians. Within this presentation the varying histologic and microbiologic conditions of the apical pulp tissue present at the initiation of root canal treatment are illustrated. On the basis of histologic and histobacteriologic observation of a large number of human biopsies, the advantages and disadvantages of this procedure will be critically analysed.
Explain the different histologic conditions present in the various clinical scenarios.
List the limitations of current instrumentation techniques in removing vital or necrotic tissue from the apical ramifications and other anatomical irregularities.
Discuss the impact of apical patency on the wound healing process.
