Gingival crevicular fluid (GCF) volume
The results showed a statistically significant increase in GCF volume in the FOA + BLE group compared with that in the FOA group at T5 (Table 
Mean values, standard deviations, and gingival fluid (µL) comparison between groups (horizontal) and time-points (vertical)(*) Both groups at each time point were evaluated using the Student’s t-test for independent groups. Similar capital letters indicate no significant difference. (**) Each group at different times was evaluated by One-way ANOVA for dependent groups and Tukey’s test. Similar lowercase letters indicate no significant difference (
