Oral health problems remain a significant concern because inadequate oral hygiene maintenance behavior can trigger gingivitis, which negatively affects an individual’s quality of life. Continuous promotive and preventive efforts are required to establish consistent health behavior changes. This scientific paper aimed to describe the implementation of dental and oral health care for Mr. A (21 years old) with gingivitis through an integrated approach and the utilization of digital media via a WhatsApp Chatbot over a period of 63 days. The method applied was a dental and oral health care approach consisting of assessment, diagnosis based on eight basic human needs, planning, implementation, and evaluation. The interventions included scaling treatment, education using the Chair Side Talk (CST) method, and continuous monitoring and reinforcement of toothbrushing behavior twice daily using the Modified Bass, Stillman, Charter, and Roll Stroke techniques through a WhatsApp Chatbot. The results demonstrated a reduction in plaque score from 24% to 0% and a decrease in the gingival index from 0.29 (mild inflammation) to 0 (healthy), along with an increased sense of responsibility in maintaining independent oral hygiene. These findings indicate that the integration of clinical treatment and digital-based behavioral assistance improved patient adherence to plaque control consistently. The evaluation showed that the integration of clinical treatment and digital-based behavioral assistance over 63 days was effective in controlling gingivitis and establishing sustainable oral health maintenance habits.
