“…Age and gender differences were observed in oxidative stress markers in plasma [42]. On the other hand, it has been observed that salivary TAC was affected by emotional and psychological factors [43], with these results being in accordance with the changes in TAC observed in our study.…”

“…The score range for both the STAI-T subscale and the STAI-S subscale falls between 20 (minimum) and 80 (maximum). STAI scores are commonly categorized as follows: "low or no anxiety" (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37), "moderate anxiety" (38)(39)(40)(41)(42)(43)(44), and "high anxiety" (45-80) [26,27].…”

(1) Background: This cross-sectional study conducted at the Faculty of Dental Medicine, Timisoara, Romania, between December 2022 and February 2023 aims to assess salivary total antioxidant capacity and pH levels in dental students experiencing non-stressful and stressful situations and explore potential correlations between these factors. (2) Methods: Saliva samples were collected during two different periods: before an Oral Health course and before the Oral Health exam, under stressful conditions. Ethical principles were followed, and informed consent was obtained. Data on age, gender, health status, drug use, smoking habits, and anxiety levels were recorded. Saliva was collected using the draining method and pH was measured using indicator paper strips. Total antioxidant capacity (TAC) was determined using a commercial assay kit. Statistical analysis involved descriptive statistics, Student’s t-test to compare pH and TAC between study groups, and Pearson’s correlation coefficient to analyze the correlation between salivary pH and TAC within each group, with p < 0.05 indicating significance. (3) Results: This study involved 80 participants, comprising 26 males and 54 females, all enrolled in the 5th year of the Oral Health course, with ages ranging from 20 to 53 and a mean age of 23.62 (±4.19) years. Pearson’s correlation results show a statistically significant negative relationship between the STAI test and TAC during the stress-free period (−0.02 **, N = 80, p < 0.01). (4) Conclusions: There are variations in saliva’s antioxidant capacity in response to different stress conditions. Dental students experienced a higher level of stress before academic assessments compared to the non-stress period during the course.

“…Obniżenie poziomu TAC zaobserwowano także u młodych, zdrowych osób w odpowiedzi na stres podczas sesji egzaminacyjnej. 31 Drugi oceniany marker, całkowity stan utlenienia TOS, okazał się być istotnie niższy u pacjentów użytkujących protezy. Ponieważ nie została zaobserwowana zmiana poziomu TAC, to wskaźnik stresu oksydacyjnego, będący stosunkiem TOS do TAC, okazał się być niższy.…”

Background and Objectives: Stress is a significant issue among dental students, with both psychological and physiological impacts affecting their academic performance. This cross-sectional study aimed to explore the relationship between academic stress and salivary biochemical markers, specifically cortisol and total antioxidant capacity (TAC), in third- and fifth-year dental students during the 2022/2023 academic year. Materials and Methods: This study included 44 participants from the Faculty of Dental Medicine at Victor Babes University, Romania. Saliva samples were collected during a low-stress period and prior to exams (high-stress period). Results: Cortisol and TAC levels were measured using ELISA and TAC assays, respectively, decreasing from an average of 3.69 (SD ± 1.49) before stress to 2.86 (SD ± 2.28) during high-stress periods (p < 0.05), while salivary cortisol levels showed a non-significant change from 23.69 (SD ± 35.6) ng/mL to 20.44 (SD ± 23.07) ng/mL; additionally, female participants exhibited a mean STAI score of 91.65 (SD ± 5.13) compared to 91.09 (SD ± 9.41) for males, indicating greater stress responses among females. Conclusions: The State-Trait Anxiety Inventory (STAI) scores confirmed elevated anxiety levels during exams. The findings suggest that academic stress negatively impacts TAC while triggering a moderate increase in salivary cortisol, underlining the need for stress management interventions in dental education.
