BACKGROUND: The current pandemic associated with SARS‑CoV‑2 has negatively influenced 
several activities, including teaching in Operative Dentistry. The aim of this study was to evaluate 
the influence of knowledge in Operative Dentistry on undergraduate students’ perception related to 
personal life and return to clinical practices classes during pandemic.
MATERIALS AND METHODS: The present research was a cross‑sectional, observational, and 
qualitative survey. The 16‑item based questionnaire was sent to undergraduate students in 2020, 
which were divided into two groups, according to the Operative Dentistry knowledge: G1‑not started 
clinical practice; G2‑already started or completed clinical practice. Questions were focused on the 
impact of the pandemic in relation to their personal lives and return to clinical practice classes. 
Chi‑square association test was performed using the SigmaPlot 12.0 software (P ≤ 0.05).
RESULTS: The response rate was 55.5% for G1 and 44.4% for G2. Regarding the questions related 
to personal life, G1 demonstrated higher percentages of fear of contracting the virus during theoretical 
classes. Same observations were found when students answered about their fear of contracting 
coronavirus during the clinical practice classes. However, G2 presented the highest agreement 
responses for the preparedness feeling to return to theoretical classroom, clinical practice classes, 
and the possibility of applying online learning.
CONCLUSIONS: In general, students’ knowledge had little influence on perception of personal life. 
However, students who have more knowledge in operative dentistry presented more security about 
returning to clinical classes.
