Objective: The aim of this study was to evaluate oral health status and practice among Buddhist monk and Nun students in Nepal. Methods: Monastery based cross sectional study was performed among 422 students from six monasteries with age group 6 to 20 years old from March to October 2021. A set of oral health related questionnaire were used followed by intraoral examinations including assessment of Decayed Missing Filled Teeth (DMFT), Gingival Status and Calculus Score along with dietary habits. Statistical analysis was performed in SPSS with descriptive, Mann Whitney test and Spearman’s correlation test. Results: Oral health knowledge attitude and practice were good in compared to other school children with same age groups. The mean DMFT Score were 1.62 ± 2.19 and mean dmft 0.59 ± 1.4 with good gingival and calculus score. Very few of them (47, 11.1%) had filled perman...

Objectives: To evaluate the marginal bone loss around dental implants using digital radiographs and to determine correlation of mesial and distal bone loss around dental implants with gender and location in either arch in a period of 3-6 months after placement and before prosthetic loading. Methods: An analytical study was undertaken from July 2021 till December 2021, after ethical clearance, in 18 patients on whom 23 implants had been placed at Dhulikhel hospital. After implant placement first radiograph was taken by CE 0297 size 2 PSP plate and Carestream (CS2100) intraoral periapical radiograph machine using paralleling technique (XcpRinn Device) and second at 3-6 months later. The radiographs were viewed using image viewer software (Vistasoft2.0.1) to calculate the bone level.

In this study, we reported the genome sequence of the highly virulent B. sorokiniana strain GN1 using the Illumina HiSeq 4000 platform. In total, 57 million 150-nucleotide paired-end clean reads were obtained and assembled into 96 scaffolds with an estimated genome size of 34.33 Mb. Furthermore, we identified genes that may be associated with strain-specific virulence and performed phylogenetic analysis of GN1 with five other Bipolaris spp. These results for GN1 will provide important information in understanding its molecular underpinning of pathogenicity and help identify novel sources of genetic resistance for improving disease resistance in barley.
