Objective: The primary etiological factor of periodontal diseases is bacterial plaque. The aim of nonsurgical periodontal treatment is to eliminate microbial deposits that settle on the tooth surface supragingivally and subgingivally and to control their recurrence. In addition, periodic checks performed for the patient to maintain adequate daily plaque control are key procedures in the treatment of periodontal diseases. In this case report, it was aimed to improve the patient's oral hygiene motivation with nonsurgical periodontal treatment. Case: A 24-year-old, systemically healthy, male patient applied to our clinic with complaints of increasing gingival enlargement and bleeding gums over time. Intraoral examination revealed that the patient had red, bleeding gums and edematous gingival enlargement. Nonsurgical periodontal treatment (supragingival-subgingival debridement) was planned for the patient. At the end of the procedure, the patient was given oral hygiene training. and was called for a check-up 1 month later. Conclusions: In the control, it was seen that the patient's gums had a healthy appearance and that the oral care habits acquired by the patient had been realized in the period until the control examination. Periodontal diseases can be significantly controlled without proceeding to the surgical phase with appropriate oral care techniques and correct treatment planning. In addition, regular dentist visits and oral hygiene training are also important.
