摘要
Abstract Aim To establish the effects of submucosal tramadol, dexamethasone and articaine on the success of inferior alveolar nerve blocks (IANB) during root canal treatment of mandibular molars with symptomatic irreversible pulpitis (SIP). Methodology In this randomized double‐blind, controlled clinical trial, 120 patients with the diagnosis of SIP in their mandibular first or second molars were included and randomly divided into four groups ( n = 30). The control group received normal saline and three experimental groups received a single dose of dexamethasone (8 mg/2 mL), or tramadol (100 mg/2 mL) or articaine (4% / 2 mL). The pre‐operative pain levels of the patients were measured with the Heft‐Parker visual analogue scale (HP VAS). All patients received standard IANB of 4% articaine with 1:200000 epinephrine. Following the observation of lip numbness, submucosal injections were administered into the mucobuccal fold adjacent to the mandibular molars. After 15 min, standard root canal treatment was initiated, and the pain intensity levels recorded from the access cavity preparation to pulp extirpation were measured with HP VAS. The duration of the anaesthesia was also evaluated. The experimental groups were compared using one‐way ANOVA or Kruskal–Wallis H‐test. The groups that were significantly different were compared pairwise using the Tukey Multiple Comparison test. The Chi‐square test was used to compare the categorical variables. Results The submucosal administration of articaine significantly increased the success rate to 63% in comparison with the control group that received submucosal saline ( p < .05). The success rate of pulpal anaesthesia was 37% in the control group, 57% in the tramadol group and 47% in the dexamethasone group, with no significant difference in the success rate among these groups. In the dexamethasone group, the duration of the anaesthetic effect of IANB was significantly longer than those in the other groups ( p < .001). Conclusions In patients with SIP, pre‐operative submucosal administration of articaine increased the success rate of IANB, while administration of dexamethasone increased the duration of anaesthesia. These agents can be used in cases where effective anaesthesia cannot be obtained during root canal treatments.
