About

The present study aimed to evaluate and compare the clinical and radiographic outcomes of full pulpotomy in mandibular molar teeth with symptomatic irreversible pulpitis according to:

A. Number of tooth surfaces defects:

• Class I cavity defect.
• Class II cavity defect.

B. Using two types of pulpotomy dressing materials:

• MTA+ (Cerkamed, Stalowa, Poland).
• Well-Root PT (Vericom, Gangwon-Do, Korea). And.,

To correlate this outcome to the quantification of two biomolecules:

• Tumor necrosis factor-alpha (TNF-⍺).
• Matrix metalloproteinases-9 (MMP-9).

Based on the results of the present study, it was concluded that:

1. Full pulpotomy using calcium silicate cements (CSCs) is considered a conservative, economical, and simple treatment option with a favorable prognosis for teeth with symptomatic irreversible pulpitis.
2. Class I and class II cavity defects do not adversely affect pulpotomy prognosis taking into consideration good aseptic condition, magnification, and proper seal of filling materials.
3. Although MTA+ and Well-Root PT yielded similar outcomes for pulpotomy in terms of success rates. Well-root PT is easier to handle compared to MTA+ and doesn't have a discoloration effect which is considered one of the drawbacks associated with MTA+.
4. Neither the preoperative pain nor the intraoperative bleeding time within 10 minutes influenced the pulpotomy outcome.
5. The concentration of TNF-α and MMP-9 biomarkers directly impact the outcome of pulpotomy.

Full description

The current study addresses an important gap in research, as the impact of cavity configuration on the outcomes of full pulpotomy has not been well explored. Comparing Class I and Class II cavity defects in this context can provide valuable insights, especially given the differences in structural integrity, bacterial infiltration risks, and restorative challenges associated with these defects.

---

60 participants in 2 patient groups

A. Number of tooth surfaces defects: • Class I cavity defect. • Class II cavity defect.

Active Comparator group

Description:

The selected patients were divided into two groups according to the number of tooth surfaces defects (n=30) (30 with class I and 30 with class II cavity defects)

Treatment:

Procedure: full pulpotomy

pulpotomy dressing materials: • MTA+ (Cerkamed, Poland). • Well-Root (Vericom, Korea).

Active Comparator group

Description:

Each group was randomly further subdivided using Microsoft Excel into two subgroups according to the dressing materials, without informing the patients which type of material was used (n=15).

Treatment:

Procedure: full pulpotomy
