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.
Background & objectives:People with hemophilia constitute a significant proportion of the population and an oral health care professional faces a considerable challenge while treating them. This study aimed to assess the oral health and dentition status as well as fear of dental treatment in patients with hemophilia and compare it with age-matched healthy subjects. Patients & methods:This single-center, case-control cross-sectional study was performed on 100 subjects with hemophilia and 100 age-matched healthy controls. Oral health and dentition status was recorded for all the subjects and scored using the simplified oral hygiene index (OHI-S), plaque index, and the dmft/DMFT index.
Background/Aims Angle fractures represent the largest percentage of mandibular fractures. They pose as a unique entity because of their codependent morphological dynamic factors, rendering the understanding of the mechanism, and treatment challenging. The aim of this study was to analyze the association between the mandibular gonial angle and the risk of mandibular angle fracture while highlighting its clinical relevance. Materials and Methods A retrospective analysis of radiographs of patients treated for mandibular fractures was done. The factors studied were as follows: the presence of a high gonial angle and an impacted third molar. The outcome was mandibular angle fracture. The gonial angle was measured using Planmeca Digital Software 3.7.0.R. Status of the third molar was also noted. Data obtained were analyzed using SPSS 22 (IBM Corp, Armonk, NY). Results The sample comprised 70 mandibular fractures (32 angle fractures and 38 non‐angle fractures). The mean gonial angle in the angle fracture group was 128.5 ± 5.4º which was 10.2° larger than in the non‐angle group (mean 118.5 ± 4.4º; P = 0.0001). Patients with a high gonial angle were 8.7 times more likely to sustain an angle fracture than those with normal or low gonial angles. A statistically significant relationship between the presence of impacted third molar and patients sustaining mandibular angle fractures was noted (P = 0.0001). Conclusion Subjects with a high gonial angle and an impacted third molar are at an increased risk for mandibular angle fracture due to direct and indirect morphological factors.
MDA was detectable in saliva in both diabetic and control groups. There was a positive significant correlation between salivary and serum MDA in diabetic and control subjects. Hence, salivary MDA appears to be an indicator of serum MDA concentration.
Background and aim. Dentists are exposed to a wide range of work-related factors that may result in various occupational diseases of which musculoskeletal disorders (MSDs) are common. The purpose of this study was to determine the prevalence and distribution of MSDs among dental professionals of our institution and to compare the prevalence of MSDs among the various dental specialists. Methods. A self-administered questionnaire, which included basic demographic details, work experience in dentistry, and work profile related questions along with the Standard Nordic Questionnaire, was administered to the study participants. Statistical analysis for the data obtained was performed using SPSS Version 16.0 (Chicago, SPSS Inc.). The chi-square test was applied to test the association between MSD and variables such as gender, designation, type of dentistry and usage of computers. The Mann Whitney U test was used to assess the relationship between MSD and age, experience, sick leave, number of patients attended per day. A p-value < 0.05 was considered significant. Results. 151 subjects participated in the study, and the prevalence of MSD in the last 12 months among dental professionals was 58.3% (88 out of 151 subjects). The most common site affected by MSD was the neck (66.7%). Also, it was noted that among various dental specialists, the Endodontists suffered the maximum (88.02%) musculoskeletal pain. Fifty individuals (33.11%) suffered from pain in multiple sites. Conclusion. Work-related musculoskeletal disorders and pain can be reduced through proper operator-patient positioning, taking adequate breaks between patients, maintaining good physical health through regular exercises.
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.
