Volume 39, Issue 0 (3-2026)
Abstract
Background and Aims: Given the rapid growth of digital technologies in dentistry, assessing dentists’ awareness and attitudes toward this transformation is essential. This study aimed to evaluate the awareness and attitudes of general dentists in Yazd-Iran toward digital dentistry in 2025.
Materials and Methods: In this descriptive-analytical study, 135 general dentists in Yazd-Iran were selected through convenience sampling. Data were collected via an online questionnaire including demographic information and the questions related to awareness and attitude. Dat were analyzed using SPSS version 27 and the statistical analysis tests were Mann-Whitney, Kruskal-Wallis, and Chi-square to examine the variables.
Results: A total of 59 men and 76 women with a mean age of 31.92 ± 7.87 years participated in the study. The mean knowledge score was 7.76 ± 2.77 out of 12. Higher knowledge and a more positive attitude were significantly associated with older age, longer work experience, and male gender (P<0.05). Overall, 74.1% of participants were unaware of the well-known CAD/CAM system, 74.8% were unfamiliar with digital implant software, and 60% did not have adequate knowledge of correct application of intraoral scanners. While, 81.5% reported an overall positive attitude, only 11.9% considered their knowledge to be aligned with modern digital technologies.
Conclusion: General dentists demonstrated a moderate level of awareness and the existing knowledge gaps warrant greater attention in both undergraduate and continuing education. Enhancing knowledge among specific groups-such as younger, less experienced, and female dentists—is essential. Significant differences in attitudes were observed according to the age, gender, and years of professional experience.

Background and Aims: The SARS-CoV-2 virus, capable of airborne transmission through aerosols, poses a significant challenge in clinical settings such as dental clinics. The use of high-speed instruments, including handpieces and ultrasonic scalers, generates considerable aerosols that, if contaminated, may facilitate infection transmission. This study aimed to detect the presence of the  SARS-CoV-2 virus in the clinical and non-clinical areas of a dental clinic.

Materials and Methods: In this cross-sectional study, 20 air samples were collected from various sections of the Dental School of Arak University of Medical Sciences. Sampling was performed using a pump equipped with a filter for two hours at a flow rate of 5 L/min and a height of 1.5 m above the floor. The samples were transported under a cold chain, the viral RNA was extracted, and then were analyzed using a specific RT-PCR kit.

Results: Out of 20 collected air samples, 3 samples (15%) tested positive for SARS-CoV-2 RNA. Two from clinical departments (restorative and fixed prosthodontics) and one from a non-clinical area
(pre-clinic).

Conclusion: The findings of this study indicated that SARS-CoV-2 RNA was detectable in some air samples from both clinical and non-clinical areas of the dental clinic. These results highlight the importance of strict adherence to infection control protocols across all sections of dental clinics to minimize the risk of airborne transmission.
