Video-Enhanced Tell-Show-Do for Managing Dental Anxiety in Children

About this trial
This study is the first of its kind to examine the effect of integrating the real oral environment with a video that supports the expressions used during the Tell-Show-Do technique (such as "we will see the cavity," "the cavity will drink juice to fall asleep," and "we will clean the tooth from the cavity"). This approach aims to enhance the Tell-Show-Do technique, build trust with the child, and reduce anxiety at the different stages of dental treatment in the clinical setting.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Children aged 4-6 years, with or without previous dental experience.
Children with a positive behavior rating according to the Frankl scale.
Children with primary molars requiring conservative dental treatment.
Disqualifiers
Children with systemic or mental disorders.
Children who received sedative or analgesic medications within the 3 hours prior to the dental visit.

Treatments tested in this trial
Behavioral Treatment
BehavioralThis group received treatment guided by the Tell-Show-Do (TSD) method. Each step was explained through simple analogies-referring to local anesthesia as 'sleepy juice' and the rubber dam as a 'trap' for the 'tooth worm.' After the explanation and instrument demonstration, restorative treatment was carried out. The protocol excluded the use of any audiovisual aids. All procedures involved conservative restoration of the mandibular primary molars
Behavioral Treatment
BehavioralChildren in this group were managed using a video-assisted Tell-Show-Do (VATSD) approach incorporating real-oral simulation. Each procedural step was preceded by a specific segment of a pre-recorded video tailored to the upcoming task. The video featured a simulated intraoral environment where dental caries was personified by an animated 'tooth worm' to explain decay and its removal. Consistent with conventional TSD, the video integrated child-friendly analogies: local anesthesia was introduced as 'sleepy juice'-depicting the 'tooth worm' falling asleep-and the rubber dam was shown as a barrier to prevent its escape. These segments sequentially covered examination, anesthesia, rubber dam placement, and cavity preparation. Each viewing was followed by a standardized verbal explanation before performing the clinical procedure. All participants underwent conservative restorative treatment of the mandibular primary molars

Trial outcomes
Primary outcomes
1
Heart Rate
Assessment tool: Pulse oximeter Measurement unit: Beats per minute (bpm) Assessment time points: Heart rate was assessed during a single dental treatment visit at baseline before treatment, after behavior management, during local anesthetic injection, before and during rubber dam placement, before handpiece use, and during restorative treatment.
Time frame
during a single dental treatment visit at baseline before treatment, after behavior management, during local anesthetic injection, before and during rubber dam placement, before handpiece use, and during restorative treatment.2
Facial Image Scale (FIS)
Assessment tool: Facial Image Scale questionnaire Measurement unit: Ordinal score (1-5) Assessment time points: Facial Image Scale was assessed during a single dental treatment visit at baseline and during treatment.
Time frame
The Facial Image Scale was assessed during a single dental treatment visit at baseline (first visit before intervention) and during dental treatment.Secondary outcomes

Oxygen Saturation (SpO₂)
Assessment tool: Pulse oximeter Measurement unit: Percentage (%) Assessment time points: Oxygen saturation was measured using a pulse oximeter and recorded during a single dental treatment visit at baseline, after behavior management, during local anesthetic injection, before and during rubber dam placement, before handpiece use, and during dental treatment.
Time frame
Baseline; after behavior management; during injection; before rubber dam placement; during rubber dam placement; before handpiece use; during treatment during a single dental treatment visit.Sponsors and contacts
