In Bangladesh, a large number of minorities or indigenous people live in Chittagong Hill Tracts (CHT) who prefer to introduce themselves as “Pahari” to create a distinguished identity from mainstream. Even in most cases, the Bangali population residing in CHT acknowledge their identity in the similar way. This distinctiveness is not solely cultural what Kymlicka assumes, rather it is ‘geo-cultural’. This paper focuses on the collective role of cultural and geo-cultural identity to define the complete ‘self’ of the marginalized population by analyzing and critiquing Will Kymlicka’s thoughts on multiculturalism. A randomly selected sample of indigenous and Bangali residents of CHT participated in this ethnographic study where data was collected through observations and face to face interviews. Qualitative data analysis procedure was followed to analyze and ultimately, thematize the collected data. The findings of this research very evidently demonstrated the acceptance of cultural varieties in today’s globalized multicultural world. Besides, it justified the importance of cultural and territorial rights of the minors which would eventually construct a complete identity for them. Hence, a perspective of cultural tolerance and promoting geo-cultural rights can advocate multiculturalism strongly boosting the true identity of a marginalized cultural group.

Background: Recent innovations in pulp treatment and root canal sealers include bioceramic. It is proven how bioceramics affect root restoration, radiculer perforation, and vital pulp therapy. Therefore, it is anticipated that using bioceramics as a root canal sealer in traditional root canal therapy for non-vital teeth will have positive results. Methods:  In this investigation, 60 nonvital teeth with periapical lesions were included. These teeth were separated into two groups of 30 teeth each and treated as follows: Group A: Bioceramics (Endocequence BCTM) sealer was used to obturate these teeth. Group B was obturated using a sealer based on Zinc Oxide Eugenol (Tubli-sealTM). Participants were contacted after 3, 6, and 12 months. The clinical outcome was assessed by assessing pain by VAS, tenderness on percussion, and using the Chi-square test and unpaired student t-test for testing differences between the two groups, with a p value of 0.05 regarded as statistically significant. Results: It was discovered that at 6 and 12 months of observation, 100% of teeth treated with Bioceramics' root canal sealer and 93.3% of teeth treated with Zinc Oxide Eugenol did not exhibit any discomfort or soreness to percussion. The differences between the groups treated with Zinc Oxide Eugenol and Bioceramics root canal sealer were not statistically significant (p > 0.05). Conclusion:It may be determined that both bioceramic-based sealers (Endosequence BC) and zinc oxide-eugenol-based sealers (Tubli-seal TM) are efficient in reducing post-operative discomfort after endodontic therapy. As a result, sealer has no effect on post-operative pain relief. Update Dent. Coll. j: 2023; 13(1): 31-34
