# Utilization of magnification devices in Vietnam’s dental practice and education: an online survey

## TL;DR

This study surveyed the use of magnification tools in Vietnamese dentistry, finding high awareness but moderate usage, with dental loupes most common and 3D-DOMs least used.

## Contribution

The study pioneers an assessment of 3D-DOMs usage in Vietnam and highlights adoption patterns across dental settings.

## Key findings

- Dental loupes were most commonly used (55.56%), followed by DOMs (25.93%) and 3D-DOMs (5.56%).
- Specialized hospitals and education institutions showed higher adoption (100% and 80%) compared to general hospitals (33.33%).
- Endodontics was perceived as the specialty benefiting most from magnification devices.

## Abstract

Advancements in dental technology have enhanced diagnostic and treatment tools, with magnification devices improving clinical precision and ergonomics. Dental loupes, conventional dental operating microscopes (DOMs), and three-dimensional digital operating microscopes (3D-DOMs) help overcome visual limitations in intricate procedures. Although widely used globally, adoption in Vietnam remains underreported. This study aimed to assess magnification device utilization in Vietnamese dental practice and education, with a pioneering focus on 3D-DOMs.

An online, questionnaire-based observational survey was conducted from October to December 2024. A total of 108 dentists responded, along with 11 dental education institutions and 5 hospitals (2 specialized, 3 general). The 28-item questionnaire, validated by a subject expert (CVI-S = 0.9), was distributed via email and messaging platforms. Google login ensured one response per participant. Data were analyzed using JASP (version 0.19.3) with descriptive statistics and Chi-square tests (p < 0.05).

Awareness was high (96.4%), while actual usage was moderate (62.96%). Usage varied by setting: specialized hospitals (100%) and education institutions (80%) showed higher adoption than general hospitals (33.33%). Dental loupes were most common (55.56%), followed by DOMs (25.93%) and 3D-DOMs (5.56%). Future usage intentions were high, particularly for loupes (81.48%). Endodontics was perceived as the specialty benefiting most. Despite cost being the primary barrier, satisfaction was high. Formal training significantly improved self-rated knowledge and satisfaction.

Despite cost and ergonomic barriers, magnification devices—especially 3D-DOMs—show strong potential. With improved training and resource allocation, they could significantly enhance diagnostic precision and clinical outcomes in Vietnamese dentistry.
