RESUMO
AIM: This study aims to evaluate the relation between salivary proteinase 3 (PR3) concentration and caries severity in children. MATERIALS AND METHODS: Six-to-eight-year age group children, from the Outpatient Department of Pediatric and Preventive dentistry at PMS Dental College were selected for the study. From these children, three groups each consisting of 28 children were selected according to the dental caries severity. Three groups were: (1) No Dental Caries group, (2) Low Dental Caries group with DMFT/DEFT score of 1-4, and (3) High Dental Caries group with DMFT/DEFT score of 5-15. Thus, a total of 84 children who satisfied the inclusion criteria were selected. The concentration of PR3 in saliva of the donors were analyzed using an ELISA kit. One way ANOVA was used for finding the relation of salivary PR3 concentration with caries severity. Pairwise comparison of PR3 concentration and caries severity were analyzed using post hoc Tukey test. RESULTS: Severity of caries and concentration of salivary PR3 showed an inverse relation. As the caries severity increases there was a decrease in PR3 concentration and vice versa. CONCLUSION: The children with high caries severity showed lower concentration of PR3 in their saliva compared with those with lower caries severity which indicates that PR3 can be used as a biomarker for assessing caries severity and also paves way to use PR3 as a caries vaccine in future. Nowadays, interest toward noninvasive and personalized dentistry has been increased. Molecular assays using salivary biomarkers can be an effective tool in detecting the caries in earlier stages and assessing a patient's caries risk. CLINICAL SIGNIFICANCE: Salivary PR3 can be used as prognostic biomarker for assessing caries severity and after treatment the value of PR3 can be used as a assessment tool to confirm its relation with caries.

Aims: To compare the length of styloid process assessed using computed tomography (CT) and panoramic radiographs (PAN). Materials and Methods: PAN were taken for 15 patients requiring CT reporting to PMS Dental College or metro scans, after obtaining informed consent and fulfilling all the inclusion and exclusion criteria. CT images were taken in metro scans. The apparent lengths of styloid process were measured in both CT and PAN using software provided with the respective machines. Ethical committee approval was obtained from PMS Dental College, Trivandrum. Results: The length of left styloid process in CT was observed 20-30 mm in 4 (27%) patients and same in PAN was observed in 5 (33%) patients. Out of 15 patients, abnormal styloid process (length >30 mm) was observed in 11 (73%) patients when measured with CT and 10 (67%) patients in PAN. In CT, the length of the styloid process on the right side was observed between 20 and 30 mm, in 3 (20%) patients. PAN of 2 (13%) patients were found between 20 and 30 mm. On the right side, abnormal styloid process (length >30 mm) was noted in 12 (80%) patients using CT and 13 (87%) patients in PAN. The length of styloid process in the combined sample (both right and left side) was found to be between 20 and 30 mm in 3 (10%) patients and styloid process >30 mm long (in both CT and PAN) was observed in 12 (40%) patients. Conclusions: This study demonstrated positive correlation between CT and panoramic measurements. "P" values were statistically significant on both sides with values of right side (P = 0.01) and left side (P = 0.002), respectively. Hence, PAN, which are routinely taken, cost-effective and involving relatively low radiation dose, may be used as substitute for CT for the purpose of diagnosis of elongated styloid process. However, for precise measurement of the length of styloid process, CT is still the imaging modality of choice.
RESUMO
Introduction: The emotional well-being of health-care employees is critical to the quality of patient care and the efficient operation of health services. Not only has the coronavirus disease-2019 (COVID-19) virus caused significant rates of morbidity and mortality around the world but it has also caused sleep disruption, stress, and pandemic-related anxiety among health-care workers. The current study examines associations among COVID-related fear, stress, and sleep quality in health professionals. Methods: From January to June 2021, a cross-sectional survey was done in Kerala among doctors, nurses, paramedical workers, and housekeeping employees. About 822 health-care providers from various districts took part in the study by completing a Google forms-based semi-structured, self-administered questionnaire. The data were coded, entered, and analyzed using SPSS 20.0. Descriptive statistical analysis, percentages, and ratios were employed to summarize the data. Results: The majority of participants were between the ages of 46 and 55 (35%). Forty-four percent and 46% of respondents, respectively, were concerned about contracting COVID-19 and spreading the virus to others. COVID-19 restrictions were the primary concern of psychological distress among respondents (90%). Approximately one-fourth of the subjects reported using sleep medication, 42% took 30 min or longer to fall asleep, and 39% slept for 6 h or less. Poor sleep quality was reported to be prevalent in 62% of the population. Conclusion: The COVID-19 pandemic has the potential to cause significant levels of fear, stress, and sleep disruption in health-care professionals. As a result, the COVID-19 pandemic represented a significant threat to their psychological health, and public health strategies should focus on improving it.
RESUMO
Background: Radiography plays an important role in detection of interproximal caries. The aim of study is to compare diagnostic ability of conventional film and photostimulable phosphor (PSP) with direct measurement using stereomicroscope in detecting proximal caries. Methodology: In this descriptive study - diagnostic test evaluation, 200 proximal surfaces of 100 extracted human posterior teeth were radiographed with dental X-ray unit. Evaluation of conventional and digital radiographs was performed twice by three observers. Carious lesions were classified based on a four-point scale (R0-R3) suggested by Abesi et al. Weighted kappa coefficients were calculated to assess intra- and interobserver agreement for each image set. Indices of diagnostic ability calculation were based on the first readings of the three observers. The scores were compared with the histological gold standard using receiver operating characteristic (ROC) analysis to evaluate diagnostic ability. Results: Intraobserver kappa coefficients calculated for each observer for each method of detecting caries ranged from 0.914 to 0.956. Interobserver kappa coefficients for each image set ranged from 0.8788 to 0.9583. The sensitivity and specificity of film for the first observer were 77.5% and 78.3% and for PSP were 77.5% and 80%, respectively. ROC analysis revealed that there were no statistically significant results (P > 0.05) between Az values for the two detection methods. Conclusion: PSP plate should be preferred over conventional films in detecting cavitated proximal caries. Further studies with more noncavitated proximal surfaces are required to conclusively establish the diagnostic ability of PSP over conventional film.
