Comparative Evaluation of Anxiety, Comfort and Time taken during Paediatric Dental Impression Techniques : Digital Scanning vs Conventional Method - A Crossover Randomised Controlled Trial.

This study is a Randomised Controlled Trial conducted for 30 participants in a single institution. In the first appointment Group A – 15 children will undergo digital impressions using an intraoral scanner, while Group B – 15 children will undergo conventional impressions with alginate material. In the second appointment crossover is performed and the sequence is reversed.

To ensure consistency and eliminate operator bias, all procedures will be performed by the same clinician.

Patient comfort, and gag reflex will be recorded immediately after the procedure using a Visual Analog Scale (VAS) and closed question respectively. The anxiety levels will be monitored with a pulse oximeter. The total time taken for each impression is measured in seconds using a stopwatch.

All impressions and subsequent measurements will be performed by the principal investigator, while an independent reviewer will observe the procedures to ensure adherence to the study protocol and to validate the accuracy of the data collection. The data collected will be subjected to statistical analysis using appropriate tests.
