About this study
Official title: Comparison of the Effectiveness of Oral Hygiene Motivation Methods Among University Students
This study aimed to compare the short-term effects of three oral hygiene motivation methods on dental plaque accumulation and gingival inflammation among Dentistry and Psychology students. It also aimed to evaluate whether the effects of these methods differed according to academic department.
This randomized clinical trial included 120 students aged 18-28 years who were enrolled in the Dentistry and Psychology departments at Cyprus Health and Social Sciences University. Participants were randomly assigned within each department to one of three oral hygiene motivation methods: verbal instruction, dental model demonstration, or plaque-disclosing agent-supported motivation.

All participants received the same standardized oral hygiene content, information leaflet, toothbrush, and toothpaste, while the motivational approach differed between groups. Professional scaling and polishing were also performed for all participants. The Silness-Löe Plaque Index (PI) and Löe-Silness Gingival Index (GI) were recorded at baseline and three weeks after the intervention.
The study evaluated changes in plaque and gingival indices to compare the effectiveness of the three motivation methods and assess whether their effects differed between Dentistry and Psychology students.
Read the detailed description
This single-center randomized clinical trial was conducted among Dentistry and Psychology students at Cyprus Health and Social Sciences University between December 2025 and February 2026. The primary aim was to compare the short-term effects of three oral hygiene motivation methods on plaque accumulation and gingival inflammation. The secondary aim was to evaluate whether the effects of these methods differed between Dentistry and Psychology students.
A total of 120 students aged 18-28 years participated in the study, including 60 Dentistry students and 60 Psychology students. Within each academic department, participants were randomly allocated to one of three motivation methods using computer-generated random allocation sequences. Six study groups were formed, each consisting of 20 participants.
At baseline (T0), plaque accumulation and gingival inflammation were assessed using the Silness-Löe Plaque Index (PI) and Löe-Silness Gingival Index (GI), respectively. Following these assessments, the assigned motivation intervention was delivered in a single session. All participants received the same standardized core oral hygiene information covering dental plaque, toothbrushing, and interdental cleaning. However, the groups differed in how this information was delivered and in the motivational approach used. In the verbal motivation group, the information was delivered verbally. In the dental model demonstration group, the same information was demonstrated on a dental model. In the plaque-disclosing agent-supported group, dental plaque was visualized intraorally using a plaque-disclosing tablet, and individualized visual feedback was provided using a mirror.
After completion of the group-specific motivation interventions, all participants underwent professional scaling and polishing on the same day. All participants also received the same standardized oral hygiene information leaflet, toothbrush, and toothpaste. No additional motivational intervention or reminder was provided during the three-week follow-up period.
Clinical measurements at baseline (T0) and three weeks after the intervention (T1) were performed by a separate examiner who was unaware of the participants' group assignments. Changes in plaque and gingival indices were evaluated to compare the effects of the three motivation methods. Additionally, the study examined whether these effects differed between Dentistry and Psychology students.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Verbal MotivationBehavioural
Participants received a single session of standardized oral hygiene education delivered verbally after baseline plaque and gingival index measurements. The education covered oral hygiene, dental plaque, toothbrushing, and interdental cleaning, including recommendations to brush twice daily for two minutes and use dental floss daily. The same standardized oral hygiene information leaflet was provided to all study groups. Following the motivation session, participants underwent professional scaling and polishing and received the same toothbrush and toothpaste as the other groups. No additional motivational intervention or reminder was provided during the three-week follow-up period.
Model DemonstrationBehavioural
Participants received a single session of standardized oral hygiene education demonstrated by the researcher on a dental model after baseline plaque and gingival index measurements. The education covered oral hygiene, dental plaque, toothbrushing, and interdental cleaning, including recommendations to brush twice daily for two minutes and use dental floss daily. The same standardized oral hygiene information leaflet was provided to all study groups. Following the motivation session, participants underwent professional scaling and polishing and received the same toothbrush and toothpaste as the other groups. No additional motivational intervention or reminder was provided during the three-week follow-up period.
Plaque DisclosingBehavioural
Participants received a single session of standardized oral hygiene education supported by intraoral application of TePe PlaqSearch™ plaque-disclosing tablets after baseline plaque and gingival index measurements. Disclosed plaque areas were shown using a mirror, inadequately cleaned areas were pointed out, and individualized visual feedback was provided. The education included recommendations to brush twice daily for two minutes and use dental floss daily. The same standardized oral hygiene information leaflet was provided to all study groups. Following the motivation session, participants underwent professional scaling and polishing and received the same toothbrush and toothpaste as the other groups. No additional motivational intervention or reminder was provided during the three-week follow-up period.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Plaque Index (Silness-Löe) from Baseline to Three Weeks
Dental plaque accumulation was assessed using the Silness-Löe Plaque Index (1964). The buccal/facial, lingual, mesial, and distal surfaces of all evaluable teeth, excluding third molars, were scored on a scale from 0 (no plaque) to 3 (abundant plaque accumulation). The mean score across evaluated sites was calculated for each participant. Change was calculated as the three-week score minus the baseline score (T1-T0). Negative values indicate a reduction in plaque accumulation.
Measured: Baseline (T0) and 3 weeks after intervention (T1)
Change in Gingival Index (Löe-Silness) from Baseline to Three Weeks
Gingival inflammation was assessed using the Löe-Silness Gingival Index (1963). The distofacial papilla, facial gingival margin, mesiofacial papilla, and lingual gingival margin of all evaluable teeth, excluding third molars, were scored on a scale from 0 (normal gingiva) to 3 (severe inflammation). The mean score across evaluated sites was calculated for each participant. Change was calculated as the three-week score minus the baseline score (T1-T0). Negative values indicate a reduction in gingival inflammation.
Measured: Baseline (T0) and 3 weeks after intervention (T1)

The secondary aim was to evaluate whether the effects of these methods differed between Dentistry and Psychology students.
A total of 120 students aged 18-28 years participated in the study, including 60 Dentistry students and 60 Psychology students. Within each academic department, participants were randomly allocated to one of three motivation methods using computer-generated random allocation sequences. Six study groups were formed, each consisting of 20 participants.
At baseline (T0), plaque accumulation and gingival inflammation were assessed using the Silness-Löe Plaque Index (PI) and Löe-Silness Gingival Index (GI), respectively. Following these assessments, the assigned motivation intervention was delivered in a single session. All participants received the same standardized core oral hygiene information covering dental plaque, toothbrushing, and interdental cleaning. However, the groups differed in how this information was delivered and in the motivational approach used. In the verbal motivation group, the information was delivered verbally. In the dental model demonstration group, the same information was demonstrated on a dental model. In the plaque-disclosing agent-supported group, dental plaque was visualized intraorally using a plaque-disclosing tablet, and individualized visual feedback was provided using a mirror.
After completion of the group-specific motivation interventions, all participants underwent professional scaling and polishing on the same day. All participants also received the same standardized oral hygiene information leaflet, toothbrush, and toothpaste. No additional motivational intervention or reminder was provided during the three-week follow-up period.
Clinical measurements at baseline (T0) and three weeks after the intervention (T1) were performed by a separate examiner who was unaware of the participants' group assignments. Changes in plaque and gingival indices were evaluated to compare the effects of the three motivation methods. Additionally, the study examined whether these effects differed between Dentistry and Psychology students.

Primary outcome
Change in Plaque Index (Silness-Löe) from Baseline to Three Weeks
Time frame: Baseline (T0) and 3 weeks after intervention (T1)
Dental plaque accumulation was assessed using the Silness-Löe Plaque Index (1964). The buccal/facial, lingual, mesial, and distal surfaces of all evaluable teeth, excluding third molars, were scored on a scale from 0 (no plaque) to 3 (abundant plaque accumulation). The mean score across evaluated sites was calculated for each participant. Change was calculated as the three-week score minus the baseline score (T1-T0). Negative values indicate a reduction in plaque accumulation.
Change in Gingival Index (Löe-Silness) from Baseline to Three Weeks
Time frame: Baseline (T0) and 3 weeks after intervention (T1)
Gingival inflammation was assessed using the Löe-Silness Gingival Index (1963). The distofacial papilla, facial gingival margin, mesiofacial papilla, and lingual gingival margin of all evaluable teeth, excluding third molars, were scored on a scale from 0 (normal gingiva) to 3 (severe inflammation). The mean score across evaluated sites was calculated for each participant. Change was calculated as the three-week score minus the baseline score (T1-T0). Negative values indicate a reduction in gingival inflammation.
