Brief Summary

The goal of this clinical trial is to determine if video modelling reduces dental anxiety in children aged 8-12 years in Depok City. The main questions it aims to answer are: Does video modelling exposure significantly lower dental anxiety levels compared to educational video or control groups? Do family sociodemographic factors, dental health knowledge, dental visit patterns, and caries experience contribute to children's dental anxiety? Researchers compare anxiety scores of the video modelling group to the educational video group and control group (no intervention) to assess anxiety reduction effects before and after controlling for confounding factors. Children aged 8-12 years are the participants. Enumerators interview them using the Modified Dental Anxiety Scale Integrated with Facial Image Scale (MDAS+FIS) before and after each intervention, while children watch assigned videos: video modelling (twice), educational video (twice), or none (control). Enumerators record all responses. Children also undergo World Health Organization Decayed, Missing, and Filled Teeth (WHO DMFT/dmft) index dental exams plus interviews about dental knowledge, practices, caries complaints, and visit patterns. Parents complete separate interviews and surveys about family sociodemographics, their own dental knowledge and practice, and their children's dental knowledge, practices, visits, and caries experience.

Outcome Measures

Primary Outcomes (2)

• Dental Anxiety Level

  Change in dental anxiety scores assessed by the Modified Dental Anxiety Scale Integrated with Facial Image Scale (MDAS+FIS). The MDAS+FIS consists of 5 items scored from 1 to 5, giving a total score range of 5 (lowest anxiety) to 25 (highest anxiety), and higher scores indicate worse (greater) dental anxiety levels.

  Baseline to post-intervention 1 (immediately after first video exposure), then to post-intervention 2 (immediately after second video exposure, 30 minutes after first post-assessment).

• Dental Health Determinants Assessment

  Structured assessment of: * Sociodemographic factors (age, sex, grade, birth order, parental education, family income, school type) * Dental visit patterns (frequency past 12 months) * Dental health knowledge (toothbrushing frequency, time, caries cause) * Caries experience using World Health Organization Decayed, Missing, and Filled Teeth (WHO DMFT/dmft) index per WHO Oral Health Surveys Basic Methods, 2013.

  Baseline

Study Arms (3)

Video Modelling

EXPERIMENTAL

Children complete baseline Modified Dental Anxiety Scale Integrated with Facial Image Scale assessment (MDAS+FIS). They then view the "Let's Go to the Dentist!" video (2 minutes 37 seconds). MDAS+FIS is assessed immediately afterward (posttest 1). After a 30-minute wait period, children view the same video again. MDAS+FIS is assessed immediately afterward (posttest 2).

Behavioral: "Let's Go to the Dentist!" Video Modelling

Educational Video

PLACEBO COMPARATOR

Children complete baseline Modified Dental Anxiety Scale Integrated with Facial Image Scale (MDAS+FIS) assessment. They then view the "Let's Brush Our Teeth!" video (2 minutes 16 seconds). MDAS+FIS is assessed immediately afterward (posttest 1). After a 30-minute wait period, children view the same video again. MDAS+FIS is assessed immediately afterward (posttest 2).

Behavioral: "Let's Brush Our Teeth!" General Dental Education Video

Control

NO INTERVENTION

Children complete baseline Modified Dental Anxiety Scale Integrated with Facial Image Scale (MDAS+FIS) assessment. They wait 30 minutes with no video intervention. MDAS+FIS is assessed at matching time points (posttest 1 equivalent and posttest 2 equivalent).

Interventions

"Let's Go to the Dentist!" Video Modelling BEHAVIORAL

A 2 minutes 37 seconds video depicting a girl demonstrating calm and cooperative behaviour throughout a complete dental visit, from arrival through discharge. Content includes: * Greeting dental staff calmly * Sitting cooperatively in dental chair * Responding positively to instructions * Maintaining calm body language during examination * Completing all procedures without distress * Leaving with positive expressions

Video Modelling

"Let's Brush Our Teeth!" General Dental Education Video BEHAVIORAL

A 2 minutes 16 seconds educational video of a boy demonstrating correct toothbrushing technique and basic dental hygiene practices. Content includes: * Proper toothbrush selection * Correct toothbrushing method * Duration of brushing * Interdental cleaning * Fluoride use
