The Covid19 pandemic has caused significant changes in staffing and training needs in the healthcare workforce. Among the practitioners impacted are dietitians and nutritionists. This study compared samples of position announcements in nutrition and dietetics from 2017 and 2021. Differences by both total number of position and position categories were found to be significantly different (p<.05) between the two time periods studied. There was a decrease of about 50% in the total number of positions posted in the first three months of 2021 as compared to the same months in 2017. Changes across position location were also significant. As a % of the total positions, specialty programs were the only category to show growth over the time period studied. These included overall increases in outpatient clinical programs focusing on HIV/AIDs, cancer, and hemodialysis, and more notably in 2021, eating disorders, obesity, and mental health programs. Differences in specific skills and credentials desired were consistent with needs in these practice areas. Awareness of changes in the employment landscape can help to better prepare students and interns to meet emerging patient care needs and workforce demands.

Background: Residual necrotic tissue or bacteria beneath gutta percha or sealer can be responsible for periapical inflammation or pain. The present study was conducted to the ability of laser in removing gutta percha from root canal using chloroform and Endosolv E. Materials & Methods: 60 freshly extracted permanent human maxillary central incisors with single and straight root canals were divided into 3 groups based on retreatment method used: group I- only diode laser; group II- diode laser along with chloroform as solvent and group III- diode laser along with Endosolv E as solvent. After completion of retreatment, roots were sectioned longitudinally and viewed under stereomicroscope at 10X magnification. The area of the remaining filling material in each half was measured. Results: The mean percentage area of remaining root canal filling material in group I was 18.2, in group II was 11.7 and in group III was 14.3. The difference was significant (P< 0.05). Conclusion: Diode laser with chloroform and diode laser with Endosolv E were significantly more effective than only diode laser in the removal of gutta-percha from the root canal.
