ABSTRACT
OBJECTIVE:
To assess the efficacy of targeted therapy based on drug sensitivity testing (DST) results in patients with acute pulpitis (AP).METHODS:
A total of 80 cases of AP were included retrospectively and divided into two groups control (Ctrl) group (conventional drug palliative therapy, n=40) and experimental (Exp) group (DST + non-resistant drugs, n=40). The clinical data and laboratory examination data of patients, including bacterial culture data, drug sensitivity test results, Ca and P contents in dental pulp, visual analogue scale (AVS), treatment satisfaction, and dental pulp incidence, were collected and analyzed.RESULTS:
Prevotella melaninogenica, Fusobacterium nucleatum, and Porphyromonas gingivalis exhibited higher resistance rates (RS) to penicillin and amoxicillin but no resistance to imipenem and metronidazole. The content of Ca and P in the dental pulp of the Exp group patients was significantly higher than that of the Ctrl group (P=0.006). The total response rate (95% vs. 77.5%, P=0.018) and overall patient satisfaction (92.5% vs. 80%, P=0.021) were also significantly higher in the Exp group than in the Ctrl group. Additionally, when the follow-up duration exceeded 1 year, the incidence of dental pulp reactions in the Exp group was significantly lower than that of the Ctrl group (P=0.026).CONCLUSIONS:
These findings suggest that Gram-negative anaerobes are the predominant oral pathogens in patients with AP. Imipenem and metronidazole demonstrate the most effective anti-infective properties against these anaerobes. Utilizing DST to select non-resistant drugs for treatment prior to therapy effectively enhances clinical outcomes for patients with AP.
