Abstract: Aim: Oral hygiene plays a critical role in preventing caries and periodontal disease in children, yet traditional health education often fails to sustain engagement. The study aimed to evaluate the effectiveness of a novel plant-watering motivational model in improving oral hygiene among children. Materials and Methods: This randomized controlled trial enrolled 40 healthy children aged 7–11 years who were randomly allocated to an experimental group (plant-watering model) or a control group (conventional oral hygiene instruction). All children received toothbrushes, toothpaste, and standardized brushing guidance. In the experimental group, a flowering plant with a drip irrigation timer served as a metaphor for dental care and a visual cue for 2-minute brushing. Outcomes included Decayed, Missing, Filled Teeth (DMFT/deft) index, Plaque Index, and Gingival Index, measured at baseline, 3 months, and 6 months. Parent-reported behavior changes were assessed through a short questionnaire. Data were analyzed using repeated-measures comparisons, with P < 0.05 considered significant. Results: Forty children (mean age 9.0 years; 50% female) completed the 6-month follow-up experiment. DMFT scores did not differ significantly between groups over time ( P = 0.984). However, the experimental group showed greater reductions in PI (baseline 1.62 to 1.20; P = 0.007) and GI (baseline 1.20 to 0.77; P = 0.001) compared to controls (between-group P < 0.0001 at 6 months). Parent feedback indicated high engagement, with 95% reporting that plant care motivated consistent brushing. Conclusions: The plant-watering motivational model significantly improved plaque control and gingival health in children. Linking oral hygiene to plant care may enhance adherence to toothbrushing routines in children.
