Comparative Evaluation of Different Obturation Techniques for Root Canal Filling of Permanent Teeth: An In-Vitro Study.

Introduction: Achieving success in root canal (RC) therapy relies on three key components: comprehensive cleaning of the canal, efficient disinfection, and proper filling of the canal space. The present study aimed to compare the efficacy of four obturation techniques: single cone (SC), GuttaCore (GC), cold lateral condensation (LC), and C Point system for RC filling of permanent teeth.

Materials And Methods: 76 extracted human mandibular first premolars were divided into four groups, with 19 teeth in each group (group A, obturation with SC technique; group B, obturation with GC; group C, obturation with LC; and group D, obturation with C Point system).

Association Between Candida albicans and COVID-19 in Complete Denture Wearers: An Observational Study.

Introduction The phenomenon of coronavirus disease 2019 (COVID-19)-related candidiasis is gaining increased attention and acknowledgment as an integral component of the severe consequences of COVID-19. The aim of the present study was to assess the association between and COVID-19 in complete denture wearers. Materials and methods An observational study was conducted on 45 complete denture wearers, who were divided into three groups as follows: Group 1, 15 subjects with mild to moderate COVID-19 infection; Group 2, 15 subjects with severe COVID-19 infection; and Group 3, 15 subjects without COVID-19 infection.
