Oral lichen planus (OLP) is a common inflammatory disease with unknown etiology. Depression, stress and anxiety are psychological factors that their influence on the expression of lichen planus by affecting the immune system's function has been confirmed. There is a probable relationship between anger and OLP expression. Therefore, the present study aimed to evaluate the association of "anger" and OLP. In this descriptive study 95 subjects were included in 3 groups. A: patients with oral lichen planus, B: positive control, C: negative control. Anger and its indices were assessed by the State-Trait Anger Expression Inventory-2 (STAXI-2) questionnaire, and pain was measured via the Visual Analogue Scale (VAS). The collected data were analyzed statistically using SPSS 18 software. The lichen planus and positive control groups bore higher total anger index (AX index) values compared with the negative control. Comparing anger expression-in (AXI) among the lichen planus and negative control groups revealed higher grades in lichen planus group. Evaluating the pain severity index (VAS) data and anger indices in lichen planus group, Spearman's Rank Correlation Test revealed a significant correlation between TAngR (reactional anger traits) and pain severity. The findings of this study indicated that there was a significant correlation between anger control and suppression of lichen planus development. On the other hand, the patients with more severe pain mostly expressed their anger physically. Based on the findings, we can make the claim that anger suppression and its control-in (gathering tension) may play a role in the development of lichen planus as a known psychosomatic disorders.
problems. The bacteria cause different diseases of the oral cavity, for example, Staphylococcus aureus bacteria lead to develop numerous diseases in the oral cavity such as angular cheilitis. S. aureus is the major cause of bacterial sialadenitis in salivary glands that is also the most common bacteria involved in the septic arthritis of temporomandibular joint which previously had arthritis. [1] In addition, the bacterium also is the reason of 90% of natural heart valve endocarditis. [2] Pseudomonas aeruginosa play an important role in necrotizing ulcerative gingivitis lesions and chronic suppurative otitis media, and
Background: The exact mechanism of the formation of salivary gland stones is unknown. Elucidating pathophysiology of the formation of salivary stones might prevent both their formation and the need for implementing invasive surgical procedures. Therefore, this study aimed to evaluate the effects exerted by some etiological factors on the formation of salivary gland stones. Methods: In this case–control study, the records of 80 patients with sialolithiasis were studied as a census from April 2011 to June 2019. These patients were referred to the Oral Medicine and the ENT departments of Tabriz University of Medical Sciences. The control group consisted of the same number of the patients with no sialolithiasis. Two groups were compared in terms of stone size, smoking, gallstones, and renal stones. Chi-squared, independent t-test, and Mann-Whitney U test were adopted to examine the quantitative variables. The data were analyzed using SPSS 17. Statistical significance was set at P<0.05. Results: Overall, 96.2% of sialoliths were found in the submandibular gland, of which 78.8% were single. Moreover, 32.5% of the patients with a history of sialolithiasis were smokers, whereas this frequency was 23.8% in the control group. In the case and control groups, 2.5% and 5% of the patients had a history of renal stones, respectively. Only one patient who had undergone a surgical procedure to remove salivary gland stones had a history of gallstones, while none of the patients in the control group had a history of gallstones. Conclusions: The results showed that the formation of salivary gland stones was not associated with smoking, history of renal stones, and gallstones. Furthermore, it was found that the numbers and sizes of salivary stones were not affected by smoking.
