Abstract
Introduction
This prospective study evaluated the outcome of a combination of non-surgical endodontic
(NSET) and vital pulp therapy (VPT) for the management of mature permanent mandibular
molar tooth with symptomatic irreversible pulpitis (SIP) and apical periodontitis
(AP).
Method
Institutional ethical clearance was obtained. Mandibular molar teeth (n= 60) with
a definitive diagnosis of SIP and AP with a radiographic periapical index score (PAI)
of ≥3 in either one of the roots (mesial or distal) were included. Block randomization
was used for allocation. In the NSET group (n=30), single visit NSET was performed
using a standardized operating protocol. In NSET-VPT group (n=30), subsequent to full
pulpotomy, the root orifice where a vital pulp was observed (as determined by the
arrest of pulpal bleed on application of 2.5% sodium hypochlorite pressure pack),
an MTA radicular barrier was placed, and it was covered with light-cured RMGIC. NSET
was performed in the root exhibiting PAI score ≥3. The tooth was permanently restored.
Postoperative pain was assessed at 24, 48 and 72- hours. Teeth were followed up clinically
and radiographically at 12-months. Presence/absence of symptoms and change in PAI
scores were noted. The data was statistically analyzed.
Results
The success rate was 90% in the NSET group and 93.3% in the NSET-VPT group. On an
inter-group comparison between the proportion of teeth healed and non-healed (radiographic),
there was
no significant difference (p>0.05).
Conclusion
The combination of NSET and VPT is a viable biologically based minimally invasive
treatment option for multi-rooted mandibular teeth with SIP and AP.
