Personalized 3D Visualization for Oral Hygiene and Motivation in Adults With Gingivitis
14 de setembro de 2026 atualizado por: Zeynep AKGÜL, Abant Izzet Baysal University
This study evaluated whether personalized three-dimensional images of possible future changes in the gums could improve oral hygiene and motivation in adults with gingivitis. Gingivitis is inflammation of the gums associated with dental plaque.
Eighty-four adults aged 18-60 years were randomly assigned to three groups of 28 participants. The groups received conventional oral hygiene education, general three-dimensional educational animations, or personalized three-dimensional visualization using models created from their own intraoral scans. All participants received the same nonsurgical periodontal treatment and instruction in toothbrushing and cleaning between the teeth.
The personalized images illustrated possible gum recession and tissue changes if periodontal care and daily plaque control were neglected. They were educational scenarios, not individual predictions of future disease. Personalized visualization was accompanied by a clinician-guided motivational discussion.
Dental plaque, gum inflammation, gum bleeding, and motivation toward dental treatment were assessed before treatment and six weeks later. The study compared these outcomes among the three educational approaches.

Armas e Intervenções
Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
Comparador Ativo: Conventional Method (CM)
Participants received nonsurgical periodontal treatment and conventional face-to-face oral hygiene education supported by practical demonstrations using a dental model and a written information leaflet.
Education covered periodontal disease, dental plaque, and daily oral hygiene practices, including the modified Bass toothbrushing technique and appropriate interdental cleaning.

Face-to-face education delivered by a clinician using a dental model and a written information leaflet.
The content covered the causes of periodontal diseases, the role of dental plaque, and daily oral hygiene practices.
Participants received instruction in the modified Bass toothbrushing technique and appropriate interdental cleaning.
|
|
Comparador Ativo: Three-Dimensional Animation (3DA)
Participants received nonsurgical periodontal treatment and clinician-guided oral hygiene education using DentalMaster three-dimensional educational software.
The educational content covered the causes and clinical signs of periodontal diseases, periodontal treatment, and daily oral care.
General three-dimensional animations illustrated potential gingival recession, periodontal tissue loss, and tooth loss associated with inadequate plaque control.
Participants were instructed in the modified Bass toothbrushing technique and appropriate interdental cleaning.

Comparador Ativo: Periodontal Disease Prediction (PDP)
Participants received nonsurgical periodontal treatment and clinician-guided education on periodontal disease and daily oral care.
Personalized three-dimensional dentogingival models generated from their intraoral scans using the Periodontal Disease Prediction (PDP) system illustrated potential gingival recession and visible tissue changes if periodontal care and plaque control were neglected.
Images were presented as conditional educational scenarios, not individualized prognostic predictions.
Visualization was accompanied by a motivational discussion addressing personal goals and barriers to oral hygiene.
Participants were instructed in the modified Bass toothbrushing technique and appropriate interdental cleaning.

Change in Full-Mouth Rustogi Modified Navy Plaque Index From Baseline to Week 6
Prazo: Baseline and 6 weeks
|
Dental plaque was assessed using the Rustogi Modified Navy Plaque Index (RMNPI) after application of a plaque-disclosing agent.
The facial and lingual/palatal surfaces of each eligible tooth were divided into nine areas, scored as 0 for absence of plaque or 1 for presence of plaque.
The full-mouth score was calculated as the proportion of assessed areas with plaque, ranging from 0 to 1, with higher scores indicating more plaque.
Third molars and teeth with crowns or cervical restorations were excluded.
Change was calculated as the week 6 score minus the baseline score; negative values indicate improvement.

Change in Full-Mouth Gingival Index From Baseline to Week 6
Prazo: Baseline and 6 weeks
|
Gingival inflammation was assessed using the Löe and Silness Gingival Index at four sites around each tooth.
Scores range from 0 to 3, with higher scores indicating more severe gingival inflammation.
A full-mouth mean score was calculated for each participant.
Change was calculated as the week 6 score minus the baseline score; negative values indicate improvement.

Change in Full-Mouth Papillary Bleeding Index From Baseline to Week 6
Prazo: Baseline and 6 weeks
|
Interdental gingival bleeding was assessed using the Papillary Bleeding Index (PBI).
Interdental papillae were scored from 0 to 4 according to the severity of bleeding elicited after probing, with higher scores indicating more severe bleeding.
A full-mouth mean score was calculated for each participant.
Change was calculated as the week 6 score minus the baseline score; negative values indicate improvement.

Intrinsic Motivation Assessed by the Dental Treatment Motivation Scale
Prazo: Baseline and 6 weeks
|
Intrinsic motivation was assessed using the seven-item intrinsic motivation subscale of the Dental Treatment Motivation Scale (DTMS).
Each item was rated on a five-point Likert scale from 1 (strongly disagree) to 5 (strongly agree).
The mean item score was calculated, ranging from 1 to 5, with higher scores indicating greater intrinsic motivation.
Scores were assessed at baseline and week 6 and compared among the three study groups.
