Evaluation of serum neuron specific enolase levels among patients with primary and secondary burning mouth syndrome

Clinical characteristics and salivary biomarkers of burning mouth syndrome

OBJECTIVES

To investigate the clinical characteristics and salivary biomarkers in each type of burning mouth syndrome (BMS) patients.

MATERIALS AND METHODS

Ninety-eight postmenopausal female patients with BMS were included. Fifty and 21 patients were assigned to the primary and secondary groups, respectively. Twenty-seven patients with both primary and secondary characteristics were assigned to the intermediate group. Comprehensive clinical characteristics and salivary biomarkers were analyzed.

RESULTS

Significant differences in age, proportion of hyposalivator patients based on unstimulated whole saliva (UWS), symptom distribution, severties of burning sensation and effect of oral complaints in daily life (Eff-life), and positive symptom distress index (PSDI) were observed among the three groups. The primary group had significant higher UWS flow rate, fewer UWS hyposalivator proportions, and lesser severity of Eff-life than the secondary group. The intermediate group had significantly greater intensities of burning sensation and Eff-life and higher PSDI score than did the primary group. The primary group had significantly higher cortisol and dehydroepiandrosterone (DHEA) levels in stimulated whole saliva than did the secondary group.

CONCLUSIONS

This study's findings show that clinical characteristics differentiate each BMS type. Cortisol and DHEA levels are potential salivary biomarkers for discriminating between the primary and secondary types of BMS.

Oral health related quality of life and the prevalence of ageusia and xerostomia in active and recovered COVID-19 Patients

Background

Salivary disturbance is associated with patients who either have an active coronavirus disease 2019 (COVID-19) or have recovered from coronavirus infection along with loss of taste sensation. In addition, COVID-19 infection can drastically compromise quality of life of individuals.

Objective

This study aimed to analyze xerostomia, ageusia and the oral health impact in coronavirus disease-19 patients utilizing the Xerostomia Inventory scale-(XI) and the Oral Health Impact Profile-14.

Methods

In this cross-sectional survey-based study, data was collected from 301 patients who suffered and recovered from COVID-19. Using Google Forms, a questionnaire was developed and circulated amongst those who were infected and recovered from coronavirus infection. The Xerostomia Inventory (XI) and Oral Health Impact Profile-14 were used to assess the degree and quality of life. A paired T-test and Chi-square test were used to analyze the effect on xerostomia inventory scale-(XI) and OHIP-14 scale scores. A p-value of 0.05 was considered as statistically significant.

Results

Among 301 participants, 54.8% were females. The prevalence of xerostomia in participants with active COVID-19 disease was 39.53% and after recovery 34.88%. The total OHIP-14 scores for patients in the active phase of infection was 12.09, while 12.68 in recovered patients. A significant difference was found between the mean scores of the xerostomia inventory scale-11 and OHIP-14 in active and recovered COVID patients.

Conclusion

A higher prevalence of xerostomia was found in COVID-19 infected patients (39.53%) compared to recovered patients (34.88%). In addition, more than 70% reported aguesia. COVID-19 had a significantly higher compromising impact on oral function of active infected patients compared to recovered patients.
