This opinion piece highlights the hidden psychological and other costs of the lack of access to dental care.

A novel brief questionnaire using a face rating scale to assess dental anxiety and fear

PURPOSE

This study aimed to evaluate the reliability and validity of a four-item questionnaire using a face rating scale to measure dental trait anxiety (DTA), dental trait fear (DTF), dental state anxiety (DSA), and dental state fear (DSF).

MATERIALS AND METHODS

Participants were consecutively selected from patients undergoing scaling (S-group; n = 47) and implant placement (I-group; n = 25). The S-group completed the questionnaire both before initial and second scaling, whereas the I-group responded on the pre-surgery day (Pre-day), the day of implant placement (Imp-day), and the day of suture removal (Post-day).

RESULTS

The reliability in the S-group was evaluated using the test-retest method, showing a weighted kappa value of DTA, 0.61; DTF, 0.46; DSA, 0.67; DSF, 0.52. Criterion-related validity, assessed using the State-Trait Anxiety Inventory's trait anxiety and state anxiety, revealed positive correlations between trait anxiety and DTA/DTF (DTA, ρ = 0.30; DTF, ρ = 0.27, ρ: correlation coefficient) and between state anxiety and all four items (DTA, ρ = 0.41; DTF, ρ = 0.32; DSA, ρ = 0.25; DSF, ρ = 0.25). Known-group validity was assessed using the initial data and Imp-day data from the S-group and I-group, respectively, revealing significantly higher DSA and DSF scores in the I-group than in the S-group. Responsiveness was gauged using I-group data, showing significantly lower DSA and DSF scores on post-day compared to other days.

CONCLUSION

The newly developed questionnaire has acceptable reliability and validity for clinical use, suggesting its usefulness for research on dental anxiety and fear and for providing patient-specific dental care.

The relationship between dental anxiety and oral health literacy with oral health-related quality of life

BACKGROUND AND AIM

Dental anxiety is a prevalent issue in society, characterized by an uneasy sensation and anticipation of negative experiences in dental settings. In essence, dental anxiety, oral health literacy, and quality of life may have a relationship with each other, however, there is a shortage of evidence examining the interplay between these factors. Therefore, this study aimed to assess the relationship between dental anxiety and oral health literacy (OHL) with oral health-related quality of life (OHRQOL).

METHODS

This is an analytical cross-sectional study conducted on 155 patients referred to the Department of Oromaxillofacial Diseases. Three questionnaires consisting of dental anxiety scale, oral health impact profile- 14, and oral health literacy adult questionnaire were used to measure anxiety, health literacy, and the quality of life-related to oral health. Scores were recorded and analyzed by IBM SPSS 24 software using independent samples T-test and ANOVA. Besides, the confirmatory modeling through the goodness of fit index of the model was applied.

RESULTS

This study involved 155 participants, with a mean age of 38.44 ± 14 years. The majority were females, comprising 99 individuals (63.9%). In this study, 89 patients (57.4%) had dental anxiety. The mean OHL score in the examined participants was 9.88 ± 3.97. Both factors of anxiety (p < 0.001) and OHL (p = 0.012) had a significant effect on the OHRQOL. There was no significant difference in the mean OHRQOL among the three categories of OHL (p = 0.085). The confirmatory modeling showed that only the fourth (p = 0.065) and fifth (p = 0.146) questions of the OHL questionnaire had no significant effect on the total score of OHL. Besides, both factors of anxiety (p < 0.001) and OHL (p = 0.012) had a significant effect on OHRQOL. With an increase of one unit in anxiety, the OHRQOL score increases by 0.31 and for a one-unit increase in the OHL score, the OHRQOL score decreases by 0.66 units.

CONCLUSION

In conclusion, it seems that considering various dimensions of oral and dental health can help patients to have reduced psychological anxiety. Notably, further multicenter studies assessing diverse variables related to dental anxiety, OHL, and OHRQOL, and considering more comprehensive study designs with longitudinal follow-up could help provide insights into how changes in dental anxiety and OHL over time affect OHRQOL.

Differences in anxiety, depression, and oral health-related quality of life among dental anxiety patients with and without reported abuse experience

This study aimed to explore the differences in anxiety, depression, and oral health-related quality of life between people with dental anxiety who reported abuse experience (n = 60) and people with dental anxiety who did not report abuse experience (n = 97). Both groups attended a dental service focused on the treatment of dental anxiety intended for people with a history of physiological or psychological trauma, or odontophobia. The participants responded to a questionnaire that included the Hospital Anxiety and Depression Scale (HADS), Oral Impacts on Daily Performance (OIDP), and the Index of Dental Anxiety and Fear (IDAF-4C+ ). The differences between groups were tested for statistical significance using Welch's T-tests, and linear regression was used to adjust for gender. The participants with reported abuse experience expressed greater psychological symptoms of anxiety and poorer oral health-related quality of life. The participants with reported abuse experience also expressed a higher fear of losing control, as well as feeling shame and disgust. This study shows that individuals with dental anxiety and a history of abuse may face more complex challenges than those with dental anxiety and no history of abuse.

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.

Psychometric Assessment of the Romanian Version of the Index of Dental Anxiety and Fear (IDAF-4C+)

BACKGROUND AND OBJECTIVES

The goal of this study was to assess the validity of the Romanian version of the Index of Dental Anxiety and Fear (IDAF-4C+) questionnaire.

MATERIALS AND METHODS

This study was conducted on a convenience sample of past patients and their acquaintances through an online questionnaire administered on the Google Forms platform between May 2021 and September 2022. The sections of the survey were demographic characteristics, the dental anxiety scale questionnaire, the IDAF-4C+ questionnaire, a single question about dental fear, and previous dental treatments.

RESULTS

In total, 239 participants were included in the study, and the mean age was 37. The IDAF-4C questionnaire had good internal validity (Cronbach alpha was 0.945). The IDAF-4C had good convergent validity, and it was positively correlated with the dental anxiety scale (r = 0.825, p < 0.001) and the question about the fear of going to the dentist (r = 0.738, p < 0.001). The questionnaire had good reliability, and the intraclass correlation was 0.985. Lower levels of dental anxiety were associated with scaling, orthodontic treatment, and dental implants. A confirmatory factor analysis was conducted after the removal of the first question from the phobia module, and residual covariance was added between items four and nine of the stimulus module, showing a good fit for the retained questions of the IDAF-4C+, grouped by module.

CONCLUSIONS

The Romanian version of the IDAF-4C+ showed acceptable psychometric properties.
