Adrenaline in pulp capping treatment of reversible pulpitis.

BACKGROUND

The role of epinephrine in the treatment of pulp capping in patients with reversible pulpitis is not clear.

AIM

To explore the role of epinephrine in the treatment of pulp capping in patients with reversible pulpitis.

METHODS

A total of 100 patients with reversible pulpitis who were treated in Anhui Jieshou People's Hospital from January 2020 to December 2021 were included in the study. They were categorized into an observation group ( = 50; treatment with adrenaline) and a control group ( = 50; treatment with zinc oxide eugenol paste). The 24-h postoperative pain, regression time of gingival congestion and redness, clinical efficacy, and incidence of adverse reactions were compared between the groups. Patients were further categorized into the ineffective and effective treatment groups based on clinical efficacy. Logistic multiple regression analysis explored factors affecting the efficacy of pulp capping treatment.

RESULTS

A significant difference in 24-h postoperative pain was observed between the groups ( < 0.05), with a higher proportion of grade I pain noted in the observation group than in the control group ( < 0.01). The regression time of gingival congestion and swelling was lower in the observation group (2.61 ± 1.44 d and 2.73 ± 1.36 d, respectively) than in the control group (3.85 ± 1.47 d and 4.28 ± 1.61 d, respectively) ( < 0.05). The 2-wk postoperative total effective rate was lower in the control group (80.00%) than in the observation group (94.00%) ( < 0.05). The incidence of adverse reactions was not significantly different between the control (14.00%) and observation (12.00%) groups ( > 0.05). The proportion of adrenaline usage was lower ( < 0.05) and that of anaerobic digestion by and was higher in the ineffective treatment group than in the effective treatment group ( < 0.05). Logistic multiple regression analysis revealed adrenaline as a protective factor ( < 0.05) and anaerobic digestion by and as risk factors for pulp capping in reversible pulpitis ( < 0.05).

CONCLUSION

Adrenaline demonstrated therapeutic efficacy in pulp capping treatment for reversible pulpitis, reducing pain and improving clinical symptoms safely. It is a protective factor for pulp capping, whereas and are risk factors. Targeted measures can be implemented to improve clinical efficacy.
