Comparing a Mobile App, AI Chatbot, and Printed Materials to Improve Parents' Dental Trauma Knowledge and Emergency Decisions (TRAUMA-AI)

2026年11月3日 更新者:Bikash Chaurasia、Lincoln University College

Comparative Effectiveness of a Mobile Application, an Artificial Intelligence Chatbot, and Traditional Print Resources on Parental Knowledge and Emergency Decision-Making for Dental Trauma in Children: A Three-Arm, Parallel-Group, Randomized Controlled Trial

Dental trauma in children may require prompt decisions by parents or caregivers. This three-arm randomized trial will compare a mobile application, an artificial intelligence chatbot, and a printed dental-trauma first-aid booklet as methods of delivering parental education. Approximately 220 parents or legal guardians will be allocated in a 1:1:1 ratio and will receive their assigned educational resource over four weeks. Parental dental-trauma knowledge and accuracy of responses to simulated emergency scenarios will be assessed at four weeks, with follow-up assessments at 12 weeks. Additional measures include confidence, usability, engagement, recognition of avulsion management, and anxiety. The study is planned in Selangor, Malaysia.

详细说明

This interventional, parallel-group, three-arm randomized controlled trial will evaluate educational modalities for parents/legal guardians of children. Participants will be recruited from the paediatric dentistry outpatient clinic and community/school outreach in the Petaling Jaya/Kelana Jaya area. Participants will be allocated using a computer-generated, concealed 1:1:1 sequence with randomly varied permuted blocks of 3 and 6, stratified by child age category and parental education (final age categories to be reconciled). Arm 1 receives a smartphone app with approximately six short interactive modules, stepwise first-aid algorithms, audiovisual content and quizzes, plus a 10-minute orientation and reminders on days 7 and 14. Arm 2 receives access to an AI chatbot restricted to a curated, guideline-based dental-trauma knowledge base, providing interactive responses to parent questions; research staff review logs for safety. Arm 3 receives a roughly 12-page A5 printed dental-trauma first-aid booklet with a standardized two-minute handover and no scheduled reminders. All three resources address common dental injuries using the same core evidence-based guidance. The intervention period is four weeks and follow-up continues to 12 weeks after randomization. Outcomes will be assessed with study-specific knowledge and simulated decision-making instruments, confidence and satisfaction measures, and modality-specific engagement metrics. Outcome assessors and data analysts are intended to be blinded, while participants and educators cannot be masked. Analyses are planned under intention-to-treat principles, using adjusted comparisons at four weeks and mixed-effects models for repeated observations; the final analysis plan will specify multiplicity and missing-data handling.

参与者组/臂
干预/治疗
实验性的:Dental Trauma First-Aid Mobile Application

Parents receive a purpose-built mobile application containing approximately six modules with guideline-based dental trauma recognition and first-aid instruction, videos, diagrams, decision algorithms and quizzes. A trained assistant provides an approximately 10-minute orientation. Participants are encouraged to complete the modules within two weeks and may access the app throughout four weeks, with reminders on days 7 and 14.

Printed educational material with diagrams and action checklists for dental avulsion, luxation, fractures and soft-tissue injury. Self-reported reading frequency and duration are collected.

实验性的:Dental Trauma AI Chatbot

Parents receive a link or QR code to an AI chatbot that answers free-text dental-trauma first-aid questions and offers guided scenarios based on a curated guideline-based knowledge base. Access is on demand throughout the four-week intervention; no minimum session count is required. Research staff review chat logs for safety.

Printed educational material with diagrams and action checklists for dental avulsion, luxation, fractures and soft-tissue injury. Self-reported reading frequency and duration are collected.

有源比较器:Printed Dental Trauma First-Aid Booklet

Parents receive an approximately 12-page A5 printed booklet with the same core dental-trauma first-aid education. A standardized two-minute handover is provided, without scheduled follow-up reminders; booklet use is self-directed over four weeks.

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Parental Knowledge of Dental Trauma Emergency Management at Week 4
大体时间:Baseline and 4 weeks after randomization (primary comparison at week 4)

Measured by the study-specific 20-item Parental Dental Trauma Knowledge Questionnaire (PDTKQ), comprising multiple-choice items based on dental-trauma first-aid guidance. Scores range from 0 to 100; higher scores indicate better knowledge. Primary analysis compares week-4 scores between randomized groups, adjusting for baseline scores.

Baseline and 4 weeks after randomization (primary comparison at week 4)
Dental Trauma Emergency Decision-Making Accuracy at Week 4
大体时间:4 weeks after randomization (primary comparison); 12-week results recorded separately as follow-up

Measured by a study-specific Dental Trauma Emergency Decision-Making Scenario Test comprising five clinical vignettes addressing avulsion, luxation, crown/root fracture and soft-tissue injury. Scored from 0 to 100 for correctness, completeness and timeliness; higher scores represent more accurate decisions.
