[Comparative study of pain releasing effect of two approaches to acute pulpitis in the night emergency].

PURPOSE: To compare the clinical effect of 2 methods for acute pulpitis in the night emergency.

METHODS

Two hundred and twenty-three patients with acute pulpitis were randomly divided into experimental group (107 cases) and control group (109 cases). Patients in the experimental group was enclosed formaldehyde cresol (FC) with CAVITON-GC after removal of crown pulp, while patients in the control group was treated with open drainage. Pain releasing effect was evaluated and analyzed 2 days after treatment．The data were analysed by t test and χ2 test with SPSS19.0 software package.

RESULTS

The average pain index of the experimental group was 1.23, which was lower than that of the control group (3.58), the difference was significant (P<0.05). The treatment efficiency was 93.46% in the experimental group, significantly higher than that in the control group (77.98%, P<0.05).

CONCLUSIONS

Treatment in the experimental group is more effective to relieve pain than simple drainage in the control group.
