Patients’ pain self-reporting scores during phonation and muscular activities. Significant pain reduction at T1 (immediately after the first PBM session) compared to T0. This continued to demonstrate a substantial improvement in pain reduction at T2 (5 h after the first PBM session) where 66.66% scored “2” on NPIS, 16.16% (case #1) scored “3” and 16.16% scored “5” (case #4). This continued to improve at T3 (second PBM session) where 83.33% (five out of six subjects) scored “0” —no pain and 16.66% scored “2” on NPIS (case #4). At T4 (three-day follow-up post complete PBM treatments), the same five cases remained pain-free, but case #4 scored mild pain “1” on NPIS, which was much less than in T3. This was related to a lack of patient’s compliance with oral hygiene instructions. At T5 and T6, none of the subjects had pain, and all of them scored “0” on NPIS.
