Impact of Oral Hygiene Instruction in Gingivitis Patients

The aim of this study is to comparatively evaluate the effectiveness of two different oral hygiene instruction methods given in addition to Phase 1 periodontal treatment in patients diagnosed with gingivitis, on periodontal clinical parameters and patient awareness scores, and to examine the relationship between the change in awareness score and clinical improvement. The main question it aims to answer is: Is video-based visual oral hygiene training as memorable and motivating as hands-on training using a model? A total of 80 patients who were diagnosed with gingivitis were included in the study. The oral health of the patients was assessed by a researcher using periodontal indices, and patients were asked to complete a 10-question questionnaire to assess their own periodontal health and oral hygiene status (T0). Following baseline measurements, all patients received standard Phase 1 periodontal treatment by another clinician. At the end of treatment, patients were randomly assigned to two different oral hygiene instruction (OHI) groups of 40 each: Group 1 (Video Group): Oral hygiene instruction in this group was provided through standard video content; Group 2 (Model Group): Oral hygiene instruction was given through practical demonstration using three-dimensional dental models. Patients were called for a follow-up appointment one month after the Phase 1 periodontal treatment (T1). All initial clinical indices were measured and recorded, and patients were asked to complete the same awareness questionnaire again.
