Associations between the perception of dental pain and pain anxiety, mental pain, and dental anxiety in Iranian sample.

OBJECTIVE: This study examined the perception of dental pain and its relationship to pain anxiety, dental anxiety, and mental pain. METHODS: This cross-sectional study was conducted on 328 patients referred to dental clinics in Kermanshah (Iran) from 2020 to 2021. The instruments used in this study included scales assessing pain anxiety, dental anxiety, mental pain, and pain perception. RESULTS: There was a significant relationship (p = .001) between pain perception with dental anxiety (r = .38), pain anxiety (r = .45), and mental pain (r = .25). CONCLUSION: Psychological factors are associated with the perception of dental pain. Given the importance of dental care to overall health, psychological interventions may help to reduce the perception of dental pain and fear of seeing dentists in Iran.

The Effect of Scaling and Root Planning on Salivary TNF-α and IL-1α Concentrations in Patients with Chronic Periodontitis.

OBJECTIVE: Periodontitis is one of the main diseases in the oral cavity that causes tooth loss. The host immune response and inflammatory factors have important role in periodontal tissue. The current study was done with the objective to determine the effect of scaling and root planning on the salivary concentrations of tumor necrosis factor-alpha (TNF-α) and interleukin-1-alpha (IL-1α). METHODS: In this quasi-experimental clinical trial, 29 patients with chronic periodontitis and 29 healthy subjects without periodontitis were studied. Clinical examination findings and salivary TNF-α and IL-1α (using ELISA method) were compared before and after scaling, root planning. RESULTS: Before starting treatment, salivary TNF-α and IL-1α concentrations were higher in healthy control group than in periodontitis group (P< 0.05). Non-surgical treatment increased the concentration of these two biomarkers in the saliva. However, increase in IL-1α concentration was not statistically significant (P= 0.056). There was a negative relationship between TNF-α and IL-1α levels with pocket depth and attachment loss (P< 0.05). CONCLUSION: Scaling and root planning improved periodontal disease indices and salivary TNF-α and IL-1α levels.
