Dental anxiety in first- and final-year Indian dental students

Dental Anxiety Among Students of the University of Rijeka, Croatia

Objectives

Dental anxiety is a common problem and a great challenge for many patients, but also for dentists - the treatment of anxious patients is considered to be one of the most stressful situations for dentists. The aim of this study was to evaluate the prevalence of dental anxiety among the students of the University of Rijeka and to detect possible differences in the level of anxiety among students of different study programs.

Participants and methods

This cross-sectional study included 290 students from different faculties of the University of Rijeka (Faculty of Law, Faculty of Humanities and Social Sciences, Faculty of Engineering, Faculty of Medicine, Faculty of Dental Medicine), 73 (25.17%) male and 217 (74.83%) female students. The study was conducted online via The Modified Dental Anxiety Scale (MDAS) in 2020 and sampling was based on voluntary responses. The Student's t-test and ANOVA were used to compare differences in MDAS scores among students.

Results

There is a significant difference in dental anxiety levels between students from the Faculty of Humanities and Social Sciences and Faculty of Dental Medicine (MDAS=11.32±4.11, MDAS=8.84±3.03, p=0.01), and also between students from the Faculty of Law and Faculty of Dental Medicine (MDAS=11.47±4.64, MDAS=8.84±3.03, p <0.01).

Conclusions

This research showed that non-dental students have a higher level of dental anxiety than dental students. Sufficient knowledge of dental and oral health could potentially overcome dental fear and anxiety. Therefore, there is a need to provide additional dental education throughout the university curriculum.

Identification of prevalence of musculoskeletal disorders and various risk factors in dentists

Purpose

The awkward and repetitive movements lead to tissue straining, potentially leading to painful musculoskeletal disorders (MSDs). MSDs in dentists result in work inefficiency and a reduction in work hours. A survey was conducted to assess the prevalence of MSDs amongst the dental population of interest.

Methods

Customized individual detail questionnaires, Standard Nordic Musculoskeletal questionnaires, and Level of Pain estimation using the Likert Scale were used to deduce the various responsible risk factors for the occurrence of MSDs in dentists. Inferential statistical analysis was done to identify the prevalence and severity of the MSDs. The Chi-Square test (95 % confidence interval) was used to identify and compare the association of risk factors involved in MSDs with the occurrence of the Effect of MSDs, the presence of MSDs, and the severity of the MSDs.

Results

The results of the study deduced that the dentists followed the sedentary work practices. The dentists experienced maximum discomfort in the neck region, which was accompanied by the discomfort experienced in the lower back, hands and wrists, making the upper extremity being more susceptible to the MSDs. Gender risk factors the, the prevalence of MSDs in the dentist's upper back, and the severity of pain in the upper back region showed a significant association level.

Conclusion

The wrist posture, the prevalence of MSDs and the severity of pain in the dentists' neck, shoulder and upper back showed a significant association level.

Dental anxiety and oral health-related quality of life before and after non-surgical periodontal treatment

OBJECTIVES

To (1) investigate dental anxiety (DA) and oral health-related quality of life (OHRQOL) before and after non-surgical periodontal treatment (NSPT) and (2) determine correlations between these patient-reported measures.

MATERIALS AND METHODS

Demographics, smoking habits, dental pain, Modified Corah's Dental Anxiety Scale (MDAS), and Oral Health Impact Profile (OHIP-14) were assessed in eighty-two participants.

RESULTS

Mean age was 48.3 years ± 11.5. At baseline, 8.5% reported being active smokers. Of non-smokers, 11% reported being an ex-smoker. After NSPT, 11.0% reported smoking. Patients' maximal pain in the last month decreased after therapy. Before treatment, participants reported higher DA. Extreme DA was observed in 8.5% of participants before therapy. Afterwards, 2.4% of participants reported extreme DA. Fear of having a foreign object in the mouth decreased after NSPT. All OHIP-14 scores, except functional limitation, improved post-treatment. Higher DA was associated with worse OHRQoL before treatment. After treatment, total MDAS score was associated with OHIP-14 global score, physical pain, psychological disability, and social disability. Worse MDAS sub-scores were associated with a higher OHIP-14 global score. Individuals with "normal/slight anxiety" had a significant improvement in OHRQoL, whereas people in the "moderate and extreme anxiety" group did not report a significant improvement. Patients diagnosed with generalized periodontitis (GP) stage III grade B and GP stage IV grade B reported less anxiety after NSPT.

CONCLUSIONS

Associations of MDAS subcategories with OHIP-14 domain scores were found before and after therapy. DA decreases and OHRQoL enhances after NSPT in patients with "normal/slight" anxiety to dental treatment. Dental practitioners should plan strategies to cope with anxiety to dental treatment and prevent decreases in OHRQoL.

CLINICAL RELEVANCE

Within the limitations of this study, DA and OHRQoL were positively correlated in patients with periodontitis, before and after NSPT, using the MDAS and OHIP-14 questionnaires. The results of our study suggest that treatment is effective in terms of alleviating DA and improving oral health, along with quality of life, in patients that report "normal/slight" anxiety to dental treatment. Nonetheless, results must be interpreted with caution since patients are generally anxious before any type of dental treatment. DA may not just be confined to NSPT per se. According to our results, evaluation of both outcomes should be an integral part of routine periodontal clinical evaluation and periodontal reevaluation of initial therapy. It is important that clinicians learn to identify patients that suffer from anxiety and take time to explain the treatment procedures to the patient, to strive for patient's emotional well-being before, during, and after dental care services. The use of specific questionnaires for both DA and OHRQoL may be more appropriate to demonstrate the psychological and quality of life differences due to periodontal disease and NSPT.

Cyclohexane-1,3-dione Derivatives as Future Therapeutic Agents for NSCLC: QSAR Modeling, In Silico ADME-Tox Properties, and Structure-Based Drug Designing Approach

The abnormal expression of the c-Met tyrosine kinase has been linked to the proliferation of several human cancer cell lines, including non-small-cell lung cancer (NSCLC). In this context, the identification of new c-Met inhibitors based on heterocyclic small molecules could pave the way for the development of a new cancer therapeutic pathway. Using multiple linear regression (MLR)-quantitative structure-activity relationship (QSAR) and artificial neural network (ANN)-QSAR modeling techniques, we look at the quantitative relationship between the biological inhibitory activity of 40 small molecules derived from cyclohexane-1,3-dione and their topological, physicochemical, and electronic properties against NSCLC cells. In this regard, screening methods based on QSAR modeling with density-functional theory (DFT) computations, in silico pharmacokinetic/pharmacodynamic (ADME-Tox) modeling, and molecular docking with molecular electrostatic potential (MEP) and molecular mechanics-generalized Born surface area (MM-GBSA) computations were used. Using physicochemical (stretch-bend, hydrogen bond acceptor, Connolly molecular area, polar surface area, total connectivity) and electronic (total energy, highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels) molecular descriptors, compound 6d is identified as the optimal scaffold for drug design based on in silico screening tests. The computer-aided modeling developed in this study allowed us to design, optimize, and screen a new class of 36 small molecules based on cyclohexane-1,3-dione as potential c-Met inhibitors against NSCLC cell growth. The in silico rational drug design approach used in this study led to the identification of nine lead compounds for NSCLC therapy via c-Met protein targeting. Finally, the findings are validated using a 100 ns series of molecular dynamics simulations in an aqueous environment on c-Met free and complexed with samples of the proposed lead compounds and Foretinib drug.

Assessment of dental anxiety using modified dental anxiety scale among adults with cleft lip and/or palate

Objectives

This study aimed to investigate dental anxiety levels among adults with cleft lip and/or palate (CL/P) and compare to adults with no orofacial cleft. The study also intended to find out the impact of cleft severity, gender and age on the perceived dental anxiety.

Methods

The study was composed of a sample of 70 adult participants who received and completed dental treatments. After sending self-addressed envelopes with consent forms and Modified Dental Anxiety Scale (MDAS) to 192 potential participants, 35 participants with CL/P (CL/P group) and 35 participants with no CL/P (control group), agreed to participate. Data were analysed using Mann-Whitney U test. A two-tailed P-value < 0.05 was considered as statistically significant.

Results

54.3% of adults with CL/P (23 females and 12 males, age range from 16 to 72 years) reported normal dental anxiety, while the remaining 45.7% reported moderate dental anxiety. No extreme dental anxiety were recorded in the CL/P group. These results were similar to the control group and there were no significant differences between groups (p > 0.05). Female participants recorded higher median anxiety scores than male participants in the CL/P group, and participants with cleft lip had higher median scores than participants with cleft lip and palate. However, these were not statistically significant.

Conclusion

The results suggest that CL/P did not affect dental anxiety levels for participants with the CL/P as there were no extreme cases and their results were comparable to a general non-cleft sample.

Factors affecting the prevalence of stress, anxiety, and depression in undergraduate Indian dental students

BACKGROUND

The objective was to assess the prevalence and the associated demographic factors of stress, anxiety, and depression among undergraduate (UG) Indian dental students and determine whether the pattern is different in government-run institutions and those managed by private authorities.

MATERIALS AND METHODS

A cross-sectional study was conducted among dental UG students from five dental colleges. Snowball sampling was used to approach 776 potential participants, resulting in a complete response from 507 students. The questionnaire consisted of demographic data; year of study; type of college; accommodation; and Depression, Anxiety, and Stress Scale (DASS)-42. Descriptive data and inferential statistics were obtained. Chi-square test was applied for categorical data to test for significance, and higher analysis was done using multiple linear regression.

RESULTS

Females and males comprised 71.8% (n = 364) and 28.2% (n = 143) of the study population, respectively. The prevalence of anxiety was highest (66.86%, n = 339), followed by depression (57.39%, n = 291) and stress (43.99%, n = 223). In terms of severity also, anxiety was the most prevalent condition as more than one-fourth of the students presented with severe and very severe scores in this aspect (25.43%, n = 129) compared to depression (14.39%, n = 73) and stress (10.09%, n = 51). Regression analysis revealed age as a strong positive predictor for all the three conditions, while staying in the hostel was a positive predictor for anxiety and stress. Being female was also an independent predictor for the high prevalence of stress.

CONCLUSION

Stress, anxiety, and depression are highly prevalent among Indian dental students. Clinical students and interns have a higher prevalence of stress than preclinical students. Age, being female, and staying in the hostel are positive predictors for the severity of stress. There is no significant difference between government and private colleges, regarding the prevalence of any psychological condition.

Influence of the previous dental visit experience in seeking dental care among young adults

Introduction:

Dental fear is one of the highly prevalent types of fear which deters patients from seeking dental cares.

Aim:

This study aims to assess the influence of a previous dental visit experience for seeking dental care among adults.

Methodology:

Young adults (n = 150, 15–26 years) with previous dental visit for care were selected randomly among outpatients’ visit in tertiary dental teaching hospital. To assess the influence of previous experience of dental visit in seeking care, we self-administered a Post-traumatic Check List-Civilian Version [posttraumatic stress disorder (PTSD)], an Autobiographical Memory Questionnaire (AMQ), and a Dental Fear Survey (DFS). The relationship of negative and positive experience of previous dental treatment, dental fear, and symptoms of PTSD was assessed using Pearson's correlations. Spearman's rho was used to find out the correlation between the DFS and PCL-C and history of dental treatment undergone.

Results:

The mean score of the DFS and PCL-C was found to be 69.57 and 40.17, respectively. The characteristics of the most negative experience including physical reactions (P = 0.936), emotional intensity (P = 0.935), sight (P = 0.941), smell (P = 0.917), and sound (P = 0.911) of dental treatment showed a significant relationship with dental fear, whereas the characteristics of the most positive memory of dental treatment showed only a few statistically significant associations with dental fear. Most of the symptoms of PTSD also show significant associations (P < 0.05) with characteristics of the most negative memory. Spearman's correlation between the DFS and the PCL-C was also statistically significant, r (150) =0.365, indicating that dental fear is indeed associated with symptoms of PTSD.

Conclusion:

There is a significant association between the characteristics of the most negative experiences of dental treatment and increased dental fear in young adults, while positive experiences did not show the inverse relationship with dental fear.
