Association Between Anxiety, Depression, and Salivary Cortisol Levels in Patients with Recurrent Aphthous Stomatitis

Oral mucosal diseases and psychosocial factors: progress in related neurobiological mechanisms

The aetiology of oral mucosal diseases, such as recurrent aphthous ulcer (RAU), oral lichen planus (OLP) and burning mouth syndrome (BMS), involves many factors, and it remains difficult for clinicians to effectively relieve disease symptoms and formulate coping strategies. With the rapid development of psychology, the role of mental and psychological factors in RAU, OLP and BMS has gradually attracted researchers attention, but the specific mechanism has not been completely determined. This narrative review describes the potential neurobiological mechanism of oral mucosal diseases and detailed psychological factors after introducing relevant research into psychological factors and oral mucosal diseases. Future research strategies and innovations needed to understand and treat oral mucosal diseases and psychological factors, as well as how to prevent oral mucosal diseases by regulation of the neuroendocrine system, are also discussed.

The Effect of Anxiety and Stress on Acceptance of Dental Procedure before and after Inhalation Sedation in Pediatric Patients: An In Vivo Study

Aim

The study aimed to assess the anxiety and stress levels on acceptance of dental treatment in child patients approaching dental extraction procedures before and after nitrous oxide (N₂O) inhalation sedation (IHS) by measuring serum amyloid A (SAA) and salivary cortisol (SC).

Materials and methods

A total of 32 children, ages ranging from 6 to 10 years, were randomly grouped as TI (before N₂O IHS) and TII (after N₂O IHS). Saliva samples were taken for biochemical evaluation of SAA before and after the procedure. Subjectively anxiety and stress levels were evaluated using modified child dental anxiety scale (MCDAS). Wilcoxon rank-sum test was used to compare the means of dental anxiety, SAA, and SC before and after N₂O IHS. The Karl Pearson correlation coefficient was employed to determine the correlation between dental anxiety and SAA and SC before and after N₂O IHS.

Results

There were significant differences in the dental anxiety level in child patients after administration of N₂O IHS, and it also showed an increased rate of acceptance of dental treatment.

Conclusion

This study showed that N₂O is a safe and effective method in reducing dental anxiety and increasing acceptance of dental treatment in child patients with improved behavior and with no adverse effects.

Clinical significance

Anxiety and stress will always hinder the acceptance of dental treatment in child patients, especially during extraction procedures. N₂O IHS is a safe and effective technique to overcome anxiety and stress in child patients and as well as allows them to undergo dental treatment with improved behavior.

Helicobacter pylori and other factors in recurrent aphthous stomatitis: A cross-sectional study

OBJECTIVES

To evaluate the role of Helicobacter pylori and other risk factors in recurrent aphthous stomatitis (RAS).

METHODS

Patients with functional dyspepsia responded to questionnaires regarding demographic and clinical data, anxiety and depression, and a specific RAS questionnaire. They underwent upper digestive endoscopy and H. pylori evaluation.

RESULTS

476 patients were included and of the 372 evaluated for H. pylori, 65.6% were H. pylori-positive. RAS was reported by 32.6% (155/476). In the bivariate analysis of the 372 patients evaluated for gastric H. pylori status, positive subjects had a lower RAS prevalence (29.9%; 73/244) than H. pylori-negative (41.4%; 53/128) (p = .026). Smoking (p = .005) and older age (p = .034) were also associated with a lower prevalence, while female gender (p = .032) and lower income (p = .046) presented higher RAS prevalence. In the multivariate analysis, H. pylori infection (p = .017), smoking (p = .001), and older age (p = .013) were protective factors, while lower income (p = .030) and anxiety (p = .042) were risk factors. In the multivariate analysis of all patients, female gender, lower income, and more schooling years were risk factors.

CONCLUSIONS

An unexpected lower prevalence of RAS was found in H. pylori-positive patients. Smoking, sex, age, income, education, and anxiety were associated with RAS.

Validation of the HADS and PSS-10 and a cross-sectional study of psychological status in patients with recurrent aphthous stomatitis

OBJECTIVES

To validate the Hospital Anxiety and Depression Scale (HADS) and the 10-item Perceived Stress Scale (PSS-10) for use in clinical studies of recurrent aphthous stomatitis (RAS) and to provide cross-sectional assessment of anxiety, depressive, and distress symptoms and perceived stress in patients with RAS.

METHODS

The validity and reliability of the HADS and PSS-10 were evaluated in 120 individuals with RAS through confirmatory factor analysis and calculation of Cronbach's alpha and omega coefficients. The prevalence of comorbid anxiety, depression, distress, and moderate-to-high perceived stress, and their association with demographics and clinical factors were assessed through cutoff scores of the HADS and PSS-10 and bivariate analyses, respectively.

RESULTS

A bi-factor model, with all items loading onto general factor with two group factors, provides the best fit to the HADS and PSS-10 data of this RAS cohort. While omega values suggested adequate reliability of total score of both scales, relatively low ranges of coefficient omega hierarchical limit utility of their subscale scores. The prevalence of anxiety, depression, distress, and moderate-to-high perceived stress was 42.5%, 18.33%, 28.33%, and 71.67%, respectively. Ethnicity, alcohol consumption, disease comorbidities, clinical type of RAS, ulcer size, pain, and RAS disease activity were found to be associated with negative psychological symptoms.

CONCLUSION

The HADS and PSS-10 are valid and reliable as general scales of psychological distress and stress in patients with RAS. Significant mental burden among RAS patients makes the use of these validated instruments a sensible and prudent practice for psychological assessment of this patient group.

Selective Removal of Necrotic Dentin in Primary Teeth Using Laser Irradiation: One-Year Clinical Evaluation of Composite Restorations

Introduction: This study aimed to evaluate the child's salivary cortisol levels, clinical performance and marginal adaptation of restorations after selective removal of necrotic dentin in primary teeth using Er: YAG laser irradiation. Methods: A double-blind clinical study was performed in children at 7-10 years. Children who had at least 2 teeth with carious lesions involving the occlusal and proximal surfaces of primary molars counterparts were selected. Removal of necrotic dentin was performed by 2 methods: Er: YAG laser irradiation and bur-preparation. Cortisol levels (n =24) was evaluated by ELISA. Clinical analysis (n =20) was performed after the restorations polish, 6 and 12 months after restorative procedure using United States Public Health Service (USPHS) method and photographs. Scanning electron microscopy (SEM) was used to analyz the marginal gap formation (n =20). The analysis of the data was performed by 95% confidence interval, Shapiro-Wilk test, Friedman and Wilcoxon post hoc tests (α =5%). Results: Cortisol levels were higher during selective removal of necrotic dentin, regardless of the method used (P>0.05). After 12 months, there was no evidence of the difference in the restorations performed on cavities prepared by both methods. SEM analysis revealed that the laser-irradiated teeth showed 10% of gaps in the full extent of restoration. For bur-prepared teeth, 20% of gaps were found at the cavosurface margin. Conclusion: The salivary cortisol levels on children that received Er: YAG laser irradiation for removal the necrotic dentin was similar to the control group. Class II restorations evaluated after 1 year period did not suffer interference by the use of Er: YAG laser irradiation.
