• Study Type: interventional

Brief Summary

The goal of this match-pair randomized study is to compare the effectiveness of the standard Audio-Tactile Performance (ATP) technique with a song-based adaptation (ATP/S) in teaching oral hygiene in visually impaired individuals aged 6 to 20 years in Kathmandu, Nepal.

1. 1.Can the ATP/S approach achieve a greater improvement in plaque control, as measured by the Patient Hygiene Performance (PHP) index, compared to standard ATP instruction over a two-week period?
2. 2.Does the rhythmic structure of a song lead to a more continuous improvement in toothbrushing task performance and theoretical oral health knowledge?

Conditions

Visually Impaired Persons; Oral Hygiene

Keywords

audio-tactile performance technique; sing along song; tooth brushing task analysis

Outcome Measures

Primary Outcomes (1)

• tooth brushing task analysis

  The oral cavity is divided into 16 surface areas. Scoring Criteria: For each area, participants are scored on four specific criteria: 1. Maintaining a 45-degree angle of the bristles. 2. Using an appropriate back-and-forth vibrating motion. 3. Ensuring adequate surface coverage. 4. Brushing for at least 5 seconds per surface. Calculation: Each correctly executed criterion earns 1 point, and the total skill level is determined by the percentage of points achieved out of the total possible points.

  from baseline to intervention, reinforment (1 week) & Final data collection (end of 2 weeks)

Secondary Outcomes (1)

• Patient hygiene performance (PHP score)

  from baseline to intervention, reinforment (1 week) & Final data collection (end of 2 weeks)

Other Outcomes (1)

• Oral Health Knowledge Questionnaire

  from baseline, intervention, reinforcement (1 week) and final data collection (end of 2 week)

Study Arms (2)

ATP with audio information file

ACTIVE COMPARATOR

Participants in this arm receive Oral Hygiene Instruction (OHI) using the standard Audio-Tactile Performance (ATP) technique. This involves hands-on training with a tooth model (dentoform) paired with a pre-recorded audio information file that provides verbal instructions on brushing techniques.

Procedure: ATP

ATP with informational song

EXPERIMENTAL

Group B (Intervention Group): Participants in this arm receive OHI using the ATP technique enhanced with a sing-along song. This method utilizes the same hands-on training with a tooth model but replaces the standard audio file with a culturally adapted song containing the brushing instructions, leveraging rhythmic entrainment to aid memory and coordination.

Behavioral: ATP with song

Interventions

ATP PROCEDURE

ATP with standard audio file

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: OUTCOMES ASSESSOR
• Masking Details: Dental Examiners: Two dental examiners were blinded to the group assignments (Control vs. Intervention). This was critical to ensure that the measurement of PHP scores, the evaluation of toothbrushing task analysis steps and the oral health knowledge were not influenced by whether the student used the standard audio or the song. two schools were randomly allocated in un-named envelop and picked on the day of intervention
