Group II subjects received verbal oral hygiene instructions verbally during their routine orthodontic visits (n = 22). Two primary outcomes were assessed using plaque index (PI) and gingival index (GI) for Ramfjord teeth to evaluate the level of oral hygiene at baseline and after 4 weeks.


Mean differences for PI and GI for group I were reduced from T1 to T2 (P < 0.05, P < 0.05) but did not significantly change for group II (P > 0.05, P > 0.05). Both PI and GI significantly reduced for group I compared to group II between T1 and T2 (P < 0.05, P < 0.05).


PI and GI all significantly decreased after 4 weeks of using active reminders of oral hygiene instructions on mobile application compared to verbal oral hygiene instructions. The study was registered at with number NCT03109769.
