Objectives: This study compared masticatory performance (MP) and masticatory efficiency (ME) between bilateral and habitual unilateral chewers and evaluated changes following bilateral chewing guidance. Methods: Fifty participants (25 bilateral, 25 unilateral chewers) chewed peanut samples before and after bilateral chewing training. MP and ME were assessed and analyzed using independent and paired t-tests. Results: Bilateral chewers showed significantly higher MP (86.80 vs. 80.32, p = 0.011) and ME (187.84 vs. 131.44, p = 0.019) than unilateral chewers. In unilateral chewers, the dominant side improved in MP (80.32 ￫ 85.32, p = 0.008) and ME (131.44 ￫ 163.76, p = 0.034) post-training; the non-dominant side also improved but remained lower than the dominant side. Conclusions: Bilateral chewing is more effective than unilateral chewing in masticatory function. Short-term bilateral chewing training enhances MP and ME, particularly in habitual unilat eral chewers.
