Introduction: Salivary biomarkers are suggested to provide a reliable, noninvasive and objective measurement of chronic psychosocial stress and helps in assessment of pivotal role of stress in causation or precipitation of multitude of health problems.
Objectives: To evaluate the usefulness of salivary alpha amylase activity as an objective indicator of chronic stress and to find out any correlation between stress- related mucosal complaints and its levels.
Study Design: Study was conducted among 50 subjects suffering from chronic stress related problems and 50 non-stressed individuals who were screened with a psychometric questionnaire. Brief case history and oral examination was carried out and about one ml of unstimulated saliva was collected. Salivary alpha amylase levels estimated were compared between study and control group and between subjects with and without oral mucosal changes using non parametric Mann Whitney U test.
Results: There was statistically significant higher salivary alpha amylase levels in study group (p =.002) and salivary alpha amylase between the oral mucosal complaints group and without oral mucosal complaints group within the total study population were found to be statistically significant (p=0.045).
Conclusions: Salivary amylase activity increases in patients with chronic psychosocial stress and may be used as a biomarker of chronic stress, but it may not be an indicator to suggest the development of stress related oral mucosal changes.
Key words:Salivary biomarker, salivary alpha amylase, psychosocial stress, sympathetic nervous system, oral mucosal changes.
Objectives: This study analyzed changes in the antegonial region in relation to age, gender, and dental status. Study design: A total of one thousand patients (five hundred males and five hundred females), who were prescribed panoramic radiograph for various purposes were included in the study. The patients were categorized according to age, gender and dentition status. Panoramic radiographs were traced and antegonial angles and depths were measured. Results: A trend of decrease in the antegonial angle and increase in antegonial depth with age was observed in both males and females. Furthermore there were differences between right and left side antegonial angle and depth, with left side angle more than right and right side depth more than left. There was a significant decrease in the values of antegonial angle and significant increase in the values of antegonial depth as the dentition status changed from completely dentulous to partially dentulous and from partially dentulous to completely edentulous state. Conclusions: The antegonial angle decreases with the advancing age and thereby increases the antegonial depth. Similar trends are seen when teeth are lost. Furthermore there is an inherent asymmetry in the antegonial region in right and left side.
Objective Changes in the gonial angle in relation to age, gender, and dental status were studied. Materials and methods The study cohort comprised 1000 patients (500 males and 500 females) who had panoramic radiographs taken for various purposes. The patients were categorized according to age, gender, and dental status. Panoramic radiographs were traced, and gonial angles were measured using a protractor. Results The gonial angle tended to increase with age in both the male and female patients. The gonial angle also increased significantly as dental status changed from completely dentulous to partially dentulous to completely edentulous. Conclusion The gonial angle increases with age and as teeth are lost.
Leprosy is a chronic infectious disease affecting primarily the skin, peripheral nerves, respiratory system and the eyes. Leprosy induces various types of clinical presentation affecting the patient´s immune response. Cellmediated immunity is considered to be the crucial defence against the disease and the magnitude of this immunity defines the extent of the disease. The article presents two case reports of manifestations of leprosy in the oro-facial region, with a brief review of various other important oro-facial manifestations of leprosy. The first report deals with granulomatous nodules in the palate while the second report presents bilateral facial palsy in leprosy patients. Both the reports gain importance due to rare oral manifestation in a borderline leprosy patient in the first case, while the second case presents a rare bilateral Bell´s sign. The role of the dental profession and especially the Oral Medicine specialist is of great importance in early diagnosis of oral lesions.
The prevalence of betel quid oral lichenoid lesions was higher than that reported in previous studies conducted in India. Increase in the frequency and duration of quid chewing was associated with increased likelihood of developing these oral lichenoid lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
