Purpose
Neurosensory disturbance (NSD) may occur following the inferior alveolar nerve blocks (IANBs).The study aims to investigate whether there is a difference in the prevalence of NSD) between patients who received lidocaine 2% and those who received articaine 4% during IANBs.
Materials and Methods
This is a double-blind, randomized clinical trial study. Patients who underwent the third molar extraction randomly were divided into two groups. In group 1, subjects IANB was performed using articaine 4%, and in group 2, lidocaine 2%.The occurrence of NSD was documented. Patients were visited within 48 hours and one week after the tooth removal. The type of anesthetic drug (articaine 4% versus Lidocaine 2%) is the study’s predictive factor.
Results
Two thousand four hundred subjects were studied in two groups (1200 subjects in each group). The mean age was 28.40 ± 6.76 years (minimum 18 and maximum 44 years). In group 1 (Lidocaine), five subjects (0.4%) had NSD after injection, and seven subjects in group 2 ( articaiene) (0.6%). Data analysis did not demonstrate any significant difference in the prevalence of NSD between the two groups. (p = 0.77)
Conclusion
Concerning the study's results, the prevalence of NSD is not higher in articaine than lidocaine in IANBs
