RESUMO
BACKGROUND/AIMS: The objectives of our study were to determine salivary α-amylase activity (stress biomarker) and its association with psychological status and quality of life (QoL), disease duration and intensity of symptoms (pain/burning) in patients with OLP. METHODS: A total of 50 subjects participated in this case-control study: 30 patients with oral lichen planus (OLP); 20 control subjects. Unstimulated whole saliva (UWS) was collected between 9 and 10 am to avoid diurnal fluctuations. Psychological status was assessed using the Croatian validated version of the original Depression, Anxiety and Stress Scale (DASS-21). The impact of oral health on QoL was assessed using the Croatian version of the Oral Health Impact Profile Questionnaire (OHIP-CRO14). RESULTS: There was no statistically significant difference in salivary α-amylase activity between patients with OLP (N=30) and control subjects (N=20) (133813.3 vs. 166815.5 U/L, p=0.314; t-test). Depression, anxiety and stress showed no statistically significant difference between patients with OLP and control subjects (p=0.076, p=0.111, p=0.209; t-test). The patients with OLP had statistically significantly poorer QoL (total) compared to control subjects (p=0.004, t-test). There was a moderate positive correlation between symptom intensity (pain/burning) and poor QoL (total) (r=0.584, p<0.001), the OHIP-CRO14 dimension "physical pain" (r=0.661, p<0.001), "psychological impossibility" (r=0.555, p<0.01), "handicap" (r=0.546, p<0.01). CONCLUSION: Although salivary α-amylase showed no statistically significant difference between patients with OLP and control subjects, the patients with OLP had poorer psychological status (three times higher scores for depression and two times higher scores for anxiety) and poorer QoL compared to the control subjects. Recognising and treating mental disorders in patients with OLP is important in order to break the "vicious circle" and achieve a better QoL in these patients.

OBJECTIVE: Since the aetiologies of cheilitis are broad and overlapping, the purpose of this cross-sectional clinical study was to examine the multiple factors involved in aetiology and the disease's clinical features. SUBJECTS AND METHODS: We analysed cheilitis prevalence, demography, clinical features, patients' habits, psychological stress, systemic diseases, vitamin B9, B12 and iron serum levels and allergy test results in a total of 130 subjects with cheilitis, plus 22 healthy subjects. RESULTS: The most common cheilitis types were: cheilitis simplex and eczematous cheilitis (28.5%); herpetic cheilitis (16.9%); and exfoliative and angular cheilitis (7.7%). Concerning bad habits, there was a significant association/connection between self-reported saliva at the corners of the mouth and angular cheilitis, and between lip licking/biting and exfoliative cheilitis. Common associated conditions were skin diseases (56.5%) and atopy (84%). Vitamin B9 and B12 serum and iron values were mostly within the normal reference range. The patients suffering from herpetic cheilitis had significantly higher psychological/mental stress levels than the control group. CONCLUSION: To our knowledge, this is the first study of cheilitis patients that has simultaneously analysed aetiological factors, characteristics of the disease and diagnostic parameters.

Data on oral lesions of coronavirus disease (COVID-19) are conflicting, and there are few evidence-based data on oral lesions directly caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The aim of this case series and literature review is to determine the prevalence of oral lesions associated with COVID-19 in outpatients and identify oral manifestations that are likely associated with COVID-19. We present 15 patients that came for their first specialist examination to the Oral Medicine Outpatient Clinic, Dental Clinic, Split, Croatia between November 2020 and January 2024. Their medical and dental history was taken following CARE guidelines. The prevalence of oral lesions associated with SARS-CoV-2 was 1.42% during the 4-year follow-up period. The most common oral lesions were nonspecific erosions, stomatitis, salivary flow disorders (xerostomia, oligosialia), salivary gland diseases (sialadenitis, chronic sialadenitis), candidiasis, pigmentation, aphthae, burning mouth syndrome, and geographic and fissured tongue. The mean latency period was 25.1 days. The site most commonly affected was the tongue (61.5%). Oral lesions associated with COVID-19 occurred in middle-aged patients, with an equal distribution by sex. They presented in a mild form and did not correlate with the severity of the clinical picture of COVID-19.

Objectives: The vitamin D receptor is involved in immunologically mediated diseases such as oral lichen planus. Some studies suggest an association between lower vitamin D concentrations and a higher risk of inflammatory conditions such as oral lichen planus. The aim of this study was to investigate 1) whether there is a difference in serum vitamin D concentration in patients with oral lichen planus compared to patients in the control group, 2) whether there is a difference in serum vitamin D concentration in patients with erosive compared to non-erosive forms of oral lichen planus, 3) whether there is a difference in serum vitamin D concentration in patients with developed oral cancer and those without cancer. Material and Methods: The study included 68 patients, 34 with oral lichen planus and 34 healthy controls. Fasting venous blood was taken from each participant to determine serum concentrations of vitamin D. Results: The T-test results confirmed a statistically significant lower serum vitamin D concentration in patients with oral lichen planus compared to the control group (p=0.001). According to the results, a statistically significant lower serum vitamin D concentration was found in patients with erosive form OLP. All five patients with oral cancer, which was developed from erosive OLP, had low serum vitamin D concentrations. Conclusions: Determination of serum vitamin D concentration could be important for monitoring OLP patients to prevent the development of severe clinical manifestations of erosive OLP and the conversion of symptomatic lesions to oral cancer.
RESUMO
To determine salivary flow rate, oral and periodontal status, oral health-related quality of life (OHRQoL), objective and subjective indexes, and serum antibody reactivity in patients with primary Sjögren's disease (pSD). Thirty-one patients with pSD and 31 control subjects participated in this cross-sectional, single-center study. The unstimulated whole salivary flow rate (UWSFR) and stimulated whole salivary flow rate (SWSFR), salivary pH, DMFT index (DMFT = D-decayed, M-missing, F-filled tooth), periodontal pocket depth (PPD), clinical attachment level (CAL), interincisal distance, OHRQoL, objective European League Against Rheumatism (EULAR) SS Disease Activity Index (ESSDAI) and subjective (EULAR SS Patient Reported Index (ESSPRI), 6-items-VAS-SS (Visual Analog Scale), Profile of Fatigue) indexes were analyzed. The patients with pSD had a blood sample taken in the morning between 7 and 10 a.m. for comprehensive laboratory analysis. Patients with pSD had statistically significant lower UWSFR (0.20 vs. 0.90 mL/min) and SWSFR (0.56 vs. 1.64 mL/min) values compared with control subjects (p < 0.001, Mann-Withney U test). Salivary pH value of pSD patients was significantly lower compared with control subjects (6.00 vs. 7.00; p < 0.001, Mann-Whitney U test). The mean DMFT index of patients with pSD compared to control subjects was not statistically significant (23.74 ± 7.28 vs. 20.77 ± 5.73; p = 0.08, t-test). Interincisal distance was significantly decreased in the pSD group compared with control subjects (43.80 ± 0.38 vs. 47.60 ± 0.50; p = 0.003, t-test). The prevalence of periodontitis was similar in patients with pSD and control subjects (83.9% vs. 77.4%; p = 0.35, λ2 test). The mean Oral Health Impact Profile (OHIP-49) total score was statistically significantly higher in pSD patients compared with control subjects (32.00 vs. 8.00; p < 0.001, Mann-Whitney U test). Patients with pSD have decreased salivary flow and salivary pH, poor oral health, decreased interincisal distance, high prevalence of periodontitis, and worse OHRQoL. These findings highlight the need for a multidisciplinary approach to the management of patients with pSD that includes physical and psychological aspects of the disease.
RESUMO
Determination of salivary flow rate and oral status in patients with primary Sjögren's Syndrome (pSS) and diffuse cutaneous systemic sclerosis (dcSSc) and comparison with control subjects. Thirty-one pSS patients, 28 dcSSc patients, and 28 control subjects participated in this single-center, cross-sectional study. Unstimulated whole salivary flow rate (UWSFR) and stimulated whole salivary flow rate (SWSFR), salivary pH, DMFT index (D-decayed, M-missing, F-filled tooth), periodontal pocket depth (PPD), clinical attachment level (CAL), interincisal distance, and OHRQoL (oral health-related quality of life) were analyzed in all three groups of subjects. Primary SS and dcSSc patients had statistically significant lower values of UWSFR (0.20; 0.38 vs. 0.91 mL/min) and SWSFR (0.56; 0.70 vs. 1.64 mL/min) compared with control subjects (p < 0.001, Kruskal-Wallis test). Salivary pH values were statistically significantly lower in pSS and dcSSc patients compared with control subjects (6.00; 6.25 vs. 7.00, respectively) (p < 0.001, Kruskal-Wallis test). The DMFT index of dcSSc patients was higher (28.50) and statistically significant compared to control subjects (20.00) (p = 0.01). The prevalence of periodontitis was the same in pSS and dcSSc patients and control subjects (p = 0.384). Primary SS and dcSSc patients had a statistically significant decreased interincisal distance compared to control subjects (43.80; 38.00 vs. 48.00) (p = 0.003 and p < 0.001, respectively). Primary SS and dcSSc patients show decreased UWSFR and SWSFR, salivary pH values closer to an acidic medium, higher DMFT index, higher prevalence of periodontitis, decreased interincisal distance, and poorer OHRQoL, i.e., poor oral and periodontal health.
RESUMO
The aim of our study was to assess the relationship between the concentration/activity of salivary stress biomarkers (cortisol, α-amylase) and the psychological profile of patients with oral lichen planus (OLP) and primary burning mouth syndrome (BMS). A total of 160 subjects participated in this case-control study: 60 patients with OLP; 60 patients with primary BMS; and 40 control subjects. Unstimulated whole saliva (UWS) was collected between 9 and 10 a.m. Salivary biomarkers were analyzed by enzyme-linked immunosorbent assays (ELISAs). Psychological assessment was evaluated with the Depression, Anxiety, and Stress Scale (DASS-21). The patients with primary BMS had higher salivary cortisol concentrations and α-amylase activity (0.52 vs. 0.44 µg/dL; 160,531 vs. 145,804 U/L; one-way analysis of variance (ANOVA) with post hoc Scheffe test) compared with patients with OLP. The patients with primary BMS had statistically significant higher scores for depression, anxiety, and stress compared with patients with OLP and control subjects (p < 0.001, Kruskal-Wallis test). There was a strong positive correlation between anxiety and depression, stress and depression, and stress and anxiety in patients with OLP and BMS (p < 0.001 and p < 0.001, respectively; Spearman's correlation). There was a good positive correlation between symptom intensity (pain/burning) and psychological profile (depression, anxiety, stress) in patients with primary BMS (r = 0.373, p = 0.003; r = 0.515, p < 0.001; r = 0.365, p = 0.004, respectively; Spearman's correlation). This case-control study is the first to compare the psychoendocrinological profile of patients with two different oral diseases. The patients with BMS showed a higher concentration/activity of salivary stress biomarkers (cortisol, α-amylase) and a stronger association with mental disorders compared with patients with OLP. However, an interdisciplinary psychoneuroimmunological approach is equally important in both patient groups (OLP and BMS), regardless of whether mental disorders are the cause or the consequence.
RESUMO
BACKGROUND: It has been reported that dyslipidemia prevalence and cardiovascular disease risk were increased in subjects with oral lichen planus diagnose. On the other hand, so far, there is no available data on the topic of cardiovascular risk (CVR) in subjects with oral lichen planus (OLP). The main aim of this study, due to lack of any other study covering this topic, was to investigate lipid profile and assess CVR in patients with OLP. MATERIALS AND METHODS: To create a routine lipid profile, we collected triglyceride serum levels, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol from 63 OLP patients and 63 healthy people representing control subjects. For every patient their individual cardiovascular risk was measured. RESULTS: In comparison with the tested control subjects, patients with OLP had all parameters of the lipid profile elevated, with no differences of statistical importance. Furthermore, the experimental (OLP) and control groups shared similar mean values of the lipid profile parameters. CONCLUSIONS: The association of OLP with cardiovascular risk was not established and further studies with more subjects involved are required to validate this connection.
RESUMO
Numerous psychoneuroimmune factors participate in complex bodily reactions to psychological stress, and some of them can be easily and non-invasively measured in saliva (cortisol, alpha-amylase, proinflammatory cytokines). Cortisol plays a crucial role in the stress response; thus, stressful events (academic examinations, cardiac surgery, dental procedures) are accompanied by an increase in cortisol levels. (A correlation between cortisol blood levels and salivary values has already been confirmed, particularly during stress). Academic stress is defined as everyday stress among students that has an impact on aspects of their psychological and physiological well-being. For example, exams are considered one of the most acute stressful experiences for students. The strength of the association between academic self-efficacy, psychological stress, and anxiety depends on a variety of factors: the type of academic challenge (e.g., oral exam), the presence of an audience, etc. Higher stress levels were predominantly recorded among younger students, primarily regarding their academic tasks and concerns (grades, exams, competing with peers for grades, fear of failing the academic year, etc.). The measurement of stress levels during academic stress can improve our understanding of the character and influence of stressful events in populations of students, preventing adverse reactions to long-term stress, such as a decreased immune response and increased anxiety.
RESUMO
Cowden syndrome (CS) is a rare autosomal dominant, hereditary, multiorgan disease with higher risk for malignancies (breast, thyroid, endometrium). Mucocutaneous lesions occur in 90% of cases and are characterized by facial trichilemmomas, oral mucosal papillomas, and benign acral keratoses. We present the case of a 39-year-old female patient with the chief complaint of "white spots" on the upper and lower attached gingiva accompanied with skin changes on the face, hands, and soles. The patient's family medical history revealed that her mother had an endometrial polyp and the sister had thyroid cancer. In the patient's medical personal history she reported follicular thyroid adenoma, thyroid abnormalities (i.e. lymphocytic thyroiditis), fibrocystic changes and juvenile breast papillomatosis, lipoma, multiple fibromas, and genitourinary tumors. Based on extensive family and personal medical history, physical examination and histopathological findings, diagnostic criteria were fulfilled for the diagnosis of Cowden syndrome.

INTRODUCTION: Oral lichen planus (OLP) is a chronic immune, inflammatory disease of the oral cavity of a still unknown etiology. MATERIALS AND METHODS: The study involved 63 subjects diagnosed with oral lichen planus and 63 subjects without pathologic changes in the oral mucosa who were classified as controls. All subjects were given a detailed medical history at first screening. The medical history of the presence of other autoimmune disease in all subjects was supported by medical records. A sample of venous blood was taken from each subject in order to determine sedimentation rate (SE) and leukocyte count (L) using standard laboratory procedures, and serum C-reactive protein (CRP) concentration values ââwere determined as well. STATISTICAL ANALYSIS: The methods of descriptive statistics, χ2-test, the Fisher's exact test, and the Student's t-test were used in the statistical processing of the results. The results were interpreted at a significance level of P <0.05. RESULTS: For all three measured inflammatory markers, there were no statistically significant differences in the number of subjects with elevated values ââbetween the test and control groups (P = 0.364 for SE; P = 1.000 for CRP and P = 0.219 for L). The prevalence of other autoimmune disease in the OLP group was higher than in the control group, with statistical significance, and the most common was cutaneous lichen in nine subjects (14.29%) with OLP and celiac disease seven subjects (11.11%). CONCLUSIONS: The results showed that there was no significant difference in the average values of the investigated inflammatory markers in blood (SE, CRP and L) between patients with OLP and control subjects, while a significantly higher incidence of other autoimmune diseases in patients with OLP was demonstrated.
RESUMO
BACKGROUND: The literature data show insufficient knowledge and awareness about oral cancer among dental and medical students. OBJECTIVE: To assess the knowledge of graduating dental students regarding oral cancer and to assess their awareness regarding the prevention and early detection of oral cancer. Also student's smoking status was examined aimed to investigate their attitude towards smoking as a risk factor for development of oral cancer and to assess the prevalence of smoking among dental students. SUBJECTS AND METHODS: The study group consisted of 83 students of the fourth and fifth years of dental medicine study who answered the questions written in the original 16-item questionnaire. RESULTS: More than half of the students considered their knowledge to be good, a quarter of them regarded their knowledge as being poor. Almost 16% of students considered their knowledge to be very good, whereas only two students rated their knowledge as 'excellent'. Students of the fifth year were more likely to be smokers compared to fourth year students (39.5% vs. 22.5%). Higher percentage of non-smokers than smokers had marked 'stop smoking' as an important preventive measure (non-smokers 91.2%, smokers 84.3%, p = 0.01). CONCLUSION: Majority of the students of fourth and fifth year of study rate their knowledge about oral cancer as good. A large number of students of both years considered hairy leukoplakia a potentially malignant disorder. Students non smokers recognize "stop smoking" as an important preventive measure unlike students smokers who show a more realistic attitude towards smoking as a risk factor for oral cancer.
RESUMO
OBJECTIVE: The aim of this study was to evaluate smoking habits, the level of knowledge and attitudes towards smoking, as well as the role of dental professionals in prevention of smoking among students of the School of Dental Medicine, University of Zagreb and compare them to attitudes of practicing Croatian dentists. MATERIALS AND METHODS: The study was carried out among 1st and 6th year dental students at the School of Dental Medicine, University of Zagreb and dentists employed in primary practice throughout Croatia. A total of 159 subjects (51 1st and 53 6th year dental students and 55 dentists) participated in the study. RESULTS: The prevalence of smoking was highest among 6th year dental students (39, 6%). It slightly decreased among dentists (34, 5%), while least smokers were found among first year dental students (7, 8%). The majority of dental student smokers expressed a desire to stop smoking (66, 7% of 1st year dental student smokers and 76% of 6th year dental student smokers), while less than half of dentist smokers had the desire to stop - only 45, 8% of them. Dental students of the 1st and 6th year of the study showed a statistically significantly higher level of desire for education about harmful smoking effects and patients counselling to quit smoking compared to dentists. The data gathered in this study indicate that it is necessary to increase awareness among dental professionals about harmful effects of smoking on oral and general health. Also, their awareness about the central role of healthcare workers as promoters of a healthy lifestyle among patients should be raised.
RESUMO
INTRODUCTION: The aim of this case report was to discuss an extremely rare oral lesion as a result of primary pulmonary tuberculosis. CASE REPORT: In this case report, the patient with refractory painless ulceration at ventral surface of the tongue was described. Detailed medical history was taken followed by clinical examination of the oral mucosa and palpation of regional lymph nodes. Clinical examination revealed ulceration on the patient's ventro-lateral surface of the tongue, approximately two centimeters in diameter. Palpation of regional lymph nodes has not revealed enlargement. The toluidine blue test of the suspected lesion was performed at each control examination. Biopsy samples for histopathologic diagnosis were taken three times. The analysis of the first biopsy sample for histopathology revealed a non-specific inflammation, the second biopsy revealed a caseous necrosis without positive Ziehl-Neelsen staining and the third biopsy revealed a granulomatous inflammation which was highly suspicious of sarcoidosis. During hospitalization, the patient underwent a complete physical examination, and laboratory and radiological diagnostics. Physical chest examination revealed bilaterally coarse crepitations and laboratory findings of his complete blood count revealed normocytic anemia of chronic disease. Radiographic examination of lungs showed multiple small nodules bilaterally and positive direct sputum smear. CONCLUSION: Although oral tuberculosis is a rare condition, it must be taken into account in differential diagnosis of refractory painless oral ulcers.
RESUMO
AIM: Patients with a solid organ transplant can have many different complications in the mouth, as a result of immunosuppression and side effects of drugs. The aim of this study was to examine the frequency and type of oral lesions in renal transplant patients, dental status, oral hygiene, oral lesions related to drugs which patients take and the time of transplantation as well as the frequency of patient's visits to the dentist in the post-transplant period. MATERIAL AND METHODS: The study was performed in a period of two years and included 100 subjects with a renal transplant during their regular control visits to the Department of Nephrology and Dialysis, Clinical Hospital Centre Zagreb and the Department of Oral Medicine, School of Dental Medicine, University of Zagreb and 100 randomly selected control subjects at the Department of Endodontics and Restorative Dentistry, School of Dental Medicine, University of Zagreb. RESULTS: Results showed a significantly higher incidence of oral lesions in patients with renal transplant (31%) compared to control subjects. The most frequent were erythematous (inflammatory changes), keratotic lesions and gingival hyperplasia. The average DMFT index was significantly lower in patients with renal transplant than in the control group. One third of patients had a subjective feeling of dry mouth. Oral hygiene was poor overall, and only a small number of subjects used the additional sustainers for oral hygiene. Most patients did not visit the dentist after the transplantation. CONCLUSION: Renal transplant patients need a comprehensive and regular dental care during the pre- and post-transplant period and a doctor of dental medicine should be part of a multidisciplinary team of medical specialists.
