Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

• Change in plaque index

  Plaque index (Silness \& Löe) to evaluate the individual oral hygiene performance of the patient. Plaque index measurements are given on a scale of 0 (no plaque) to 3 (presence of plaque or tartar buildup), and higher scores indicate less success in individual oral hygiene practices for the patient.

  Baseline (T0) and 1 month (T1)

• Change in gingival index

  Gingival index (Löe\&Silness) evaluates the inflammatory response of the gingiva due to plaque accumulation. In this measurement, the inflammation of the gums is evaluated using a numerical value between 0 (no edema, healthy gums) and 3 (red, bleeding, and swollen gums), and the higher the score, the greater the severity of gum disease.

  Baseline (T0) and 1 month (T1)

• Change in awareness score

  The numerical value recorded as the awareness score was obtained from the patients' answers to 10 questions in the survey. Each question was answered with a value between "0" (disagree) and "4" (strongly agree), and the total value obtained from the answers to the 10 questions represents the sum. As the score approaches the minimum value of 0, it indicates that the individual has fewer complaints related to gum disease, while a total score close to the maximum value of 40 indicates that the individual suffers more from the discomfort caused by gum disease.

  Baseline (T0) and 1 Month (T1)

Secondary Outcomes (2)

• Change in probing depth

  Baseline (T0) and 1 Month (T1)

• Change in bleeding on probing

video group

EXPERIMENTAL

Phase 1 periodontal therapy + Video-based oral hygiene instruction

Behavioral: video-based oral hygiene instruction

model group

EXPERIMENTAL

Phase 1 periodontal therapy + model-based oral hygiene instruction

Behavioral: Model-based oral hygiene instruction

Interventions

video-based oral hygiene instruction BEHAVIORAL

Following standard Phase 1 periodontal therapy (scaling and root planing), patients in this group received standardized oral hygiene instruction via a video presentation. The video demonstrated proper tooth brushing and interdental cleaning techniques. A link to the video was also provided to the patients for at-home reinforcement.

Model-based oral hygiene instruction BEHAVIORAL

Following standard Phase 1 periodontal therapy (scaling and root planing), patients in this group received practical oral hygiene instruction demonstrated on a 3D dental model by the researcher. The demonstration included proper tooth brushing and interdental cleaning techniques.
