Objective: To evaluate unstimulated and stimulated salivary characteristics of 12-13-year-old schoolchildren with and without dental erosion.

Design: The subjects were sixty schoolchildren from 12-13 years old (30 boys and 30 girls) with dental erosion and sixty age- and sex-matched controls. Unstimulated and stimulated whole saliva were collected. Flow rate, pH level, buffering capacity, bicarbonate, buffer base, calcium, phosphorus and urea concentrations of whole saliva were measured. All data were analysed using SPSS 13.0.

Results: The flow rate, pH, bicarbonate, buffer base, calcium, phosphorus, and urea of unstimulated and stimulated saliva did not differ significantly between the dental erosion group and the control group (P>0.05). The stimulated salivary buffering capacity did not vary between the two groups (Fisher's exact test, P>0.05).

Conclusion: The salivary characteristics are similar amongst 12-13-year-old schoolchildren with and without dental erosion in Southern China.

Biophysical stimuli such as alternating electrical fields can mimic endogenous electrical potentials and currents in natural bone. This can help to improve the healing and reconstruction of bone tissue. However, little is known about the combined influence of biomaterials and alternating electric fields on bone cells.

Natural resistance to Mycobacterium tuberculosis (Mtb) infection in some people with HIV (PWH) is unexplained. We performed single cell RNA-sequencing of bronchoalveolar lavage cells, unstimulated or ex vivo stimulated with Mtb, for 7 PWH who were TST & IGRA positive (called LTBI) and 6 who were persistently TST & IGRA negative (called resisters). Alveolar macrophages (AM) from resisters displayed a baseline M1 macrophage phenotype while AM from LTBI did not.

Management of radiotherapy-induced hyposalivation using photobiomodulation therapy: a case series.

It is not uncommon for individuals receiving radiotherapy for head and cancers to experience dry mouth sensation (xerostomia), salivary hypofunction (hyposalivation) and taste changes. The present study aimed to evaluate the short-term effectiveness of biweekly photobiomodulation therapy (PBMT) in managing these radiotherapy-induced adverse effects and its impact on oral health-related quality of life. Ten patients who developed xerostomia and hyposalivation secondary to radiotherapy for head and neck cancer were included.

This study aimed to identify the clinical characteristics of patients with burning mouth syndrome (BMS) according to the low frequency/high frequency (LF/HF) ratio in the heart rate variability test and to evaluate the potential of the LF/HF ratio as an indicator for the diagnostic or predictive assessment of patients with BMS. A total of 469 patients with BMS who visited the Oral Diseases Clinic of Kyung Hee University Korean Medicine Hospital between January 1, 2018, and December 31, 2022, were included in the study. The patients were asked to rate their tongue pain on a visual analog scale before and after treatment.

Functional Characteristics of the Crosstalk Between Vocal Fold Fibroblasts and Macrophages-The Role of Vibration in Vocal Fold Inflammation.

Article Synopsis
  • The study explored how human vocal fold fibroblasts (hVFF) interact with macrophages in the presence of cigarette smoke extract (CSE) and vibration, focusing on vocal fold inflammation.
  • Researchers cultured hVFF with CSE, applying either static or dynamic conditions, and then measured various mRNA and protein levels to assess inflammation.
  • Findings revealed that vibration may reduce CSE-induced inflammatory responses in hVFF, suggesting potential mechanisms to address voice disorders linked to smoking-related inflammation.
