Aim: The aim of the study was the assessment of maximum voluntary bite force (MVBF) and electromyography (EMG) of masseter muscle pre- and post-oral rehabilitation in children between 3 years and 14 years of age. Materials and methods: The study population consisted of 60 children aged 3–14 years of age divided into 3 groups of 20 each based on the dentition. The MVBF and the EMG of the masseter muscle were recorded pre- and post-oral rehabilitation. Results: The MVBF in phase I and II for right side was found to be 32.32 and 36.59 kg, respectively, and for the left side was found to be 32.24 and 36.53 kg, respectively, which was highly significant. Electromyography of masseter muscle for both the phases was found to be 283.87 μV in phase I and 329.64 μV in phase II with a high significance. Conclusion: A significant improvement was observed post-oral rehabilitation in the MVBF and the electromyographic activity of the masseter muscle. Maximum voluntary bite force was seen more in males as compared to females with no side predilection. Hence, the effect of dental caries on bite force and masticatory muscle activity was established.
