Pulpal regeneration allows "pulp-like" tissue to re-grow into the immature root and continue the development of the root. This provides the root with stronger, thicker root walls. Here's another successful case of pulpal regeneration.
This young patient had a traumatic incident to tooth #9 5 months earlier. At our initial evaluation, the tooth responded normal to thermal testing. We decided to monitor the tooth over time. At a follow up visit, #9 exhibited no response to thermal testing with an open apex.
Pulpal regeneration was started. Complete pulpectomy was performed with minimal instrumentation to the apex, and irrigation with 5.25% NaOCl. A blood clot was initiated into the canal, a collagen plug was placed and an (white) MTA coronal barrier was placed below the level of the CEJ.
At six month recall, the tooth is asymptomic and functional. The radiograph shows dentinal bridging apical to the MTA placed intracoronally.
