ABSTRACT
The first case of pneumonia of unknown origin was identified in Wuhan, the capital city of Hubei province situated in the Republic of China. The pathogenic organism that has been identified as a causative organism is a novel enveloped RNA betacoronavirus which has been designated as' severe Acute Respiratory Syndrome Coronavirus- 2 (SARS-CoV-2). This virus has been found to have a similar phylogeny to SARS-CoV. The novel Coronavirus or COVID-19 can be symptomized through clinical manifestations like- Pyrexia or fever, Cough, Dyspnea/difficulty in breathing, Myalgia/muscle pain, and constant fatigue. In the later stages, these symptoms worsen leading to severe pneumonia, acute respiratory distress syndrome, sepsis, and multiple organ failure. These days, this pandemic is emerging as a major threat for dental health-care professionals. The dental surgeons are at greater risk of novel coronavirus infections due to direct contact with infected patients and exposure to contaminated blood, saliva, and other body fluids. This article deals with viral structure, clinical symptoms, and modes of transmission, recommended measures to prevent its spread in dental operatories.
ABSTRACT
BACKGROUND: The psychological impact of anxiety, stress, and depression among health care and nonhealth-care professionals in India contribute significantly to the global burden of mental illness in the world. Impaired mental health and stress influence the efficiency and productivity of work. Long-term professional stress among individuals can lead to chronic illness, increased blood pressure, and many systemic disorders. The aim of this study was to assess the prevalence of anxiety, stress, and depression among the health care and nonhealth-care professionals in India. MATERIALS AND METHODS: This prospective survey-based study included 200 study participants (80 nonhealth care and 120 health-care workers) who were asked to submit their feedback and opinion on a questionnaire survey. Depression, stress, and anxiety were scored as per patient health questionnaire-4 and UCLA scale. The reliability of questionnaires was assessed using the Cronbach's alpha (r = 0.90). The statistical analysis was done using the Chi-square test. RESULTS: Higher prevalence ratio of anxiety, depression, and stress was observed among nonhealth care compared to health-care professionals. CONCLUSION: Psychological disturbances were found to be higher among nonmedical when compared to health-care workers or professionals. Thus, psychological counseling is required to manage the stress levels in both health care and nonhealth-care professionals.
ABSTRACT
BACKGROUND: Dental caries is a microbiological disease affecting teeth which has both genetic as well as environmental factors. Dermatoglyphics is the study of fingerprint patterns and is also genetically determined. This study is aimed to determine a correlation between dermatoglyphic patterns and caries susceptibility among children. METHODS: A total of 250 children (125 each of case and control groups) were selected. Dental caries status was evaluated using the DMFT index while dermatoglyphic study was performed by recording impressions using stamp pad-ink method. RESULTS: Higher frequency of all dermatoglyphic patterns was observed among female subjects with caries as compared to caries-free subjects as well as compared to male subjects. CONCLUSION: Dermatoglyphics can be employed as a positive indicator of caries susceptibility among children and holds importance in the area as future caries predictor.
ABSTRACT
BACKGROUND: The success rate of dental implants depends on the amount of crestal bone around the implants. Crestal module is the transosteal region of implant that is designed to receive the prosthetic component. The design of crestal module influences the crestal bone loss around implants. AIM: The purpose of this study was to evaluate and compare the crestal bone loss around implants with smooth collar and implants with micro threaded rough collar design. MATERIALS AND METHODS: A total of 150 individuals received 100 dental implants. Each individual received one implant with smooth collar design (Group-A) and one implant with microthreaded rough collar design (Group-B) in the posterior edentulous region. All the 100 implants were prosthetically loaded after a healing period of 3 months. Crestal bone loss was measured on mesial, distal, buccal, and lingual side of each implant using periapical radiographs before loading (baseline), immediately after loading, 6, and 12 months after loading. RESULTS: The average crestal bone loss 12 months after loading the implants in Group A and Group B was 3.75 mm and 3.23 mm, respectively, the value being statistically significant (P < 0.05). In both Group A and Group B, the average crestal bone loss was maximum on the lingual side followed by buccal, distal, and mesial sides. CONCLUSION: Crestal bone loss around rough-surfaced microthreaded neck implants was significantly lower than smooth-surfaced neck implants.
