Introduction: The evaluation of the pulpal threshold to sensibility tests, as a side effect of possible neuropathy in Multiple Sclerosis (MS) patients, is a novel issue. This research extended prior work on evaluation of the response to electric pulp testing in multiple sclerosis patients without a history of trigeminal neuralgia. This survey has made an attempt to investigate the relationship between some sensibility pulp tests thresholds and the disease duration in MS patients.Materials and Methods: One hundred twenty-four maxillary central incisors belonging to relapsing-remitting MS patients were encompassed in this survey. The patients were unified, the age range was 18–50 years old, suffered from relapsing-remitting MS, and no history of trigeminal neuralgia. Electric and cold pulp sensibility tests were performed for all teeth. Electric pulp testing (EPT) results were recorded based on the pulp tester's grade that evoked a response. Data were analyzed with paired T-test, Fisher exact test, and spearman correlation. The significance level was set as p Results: Based on these findings, the mean value of response to EPT was 2.69 ± 1.17 and the time of the response to the cold test was 2.61 ± 1.03 seconds, respectively. Males and the older group significantly responded to a cold test in a longer time. No significant difference was recognized between the pulpal response to EPT and the cold test in patients with and without sensory-motor involvement (p > 0.05). According to spearman analysis, there was a significant positive correlation between electrical pulp threshold and the duration time to respond to the cold test (P = 0.025, r = 0.2).Conclusions: The application of the pulpal sensibility test in MS patients would lend itself well for use by clinicians. Patients with longer disease duration bared significantly higher threshold for EPT and the cold test in their maxillary central incisors. |
