Background. Microbiology is a mandatory component in all medical schools. The microbiology lab sessions at Arabian Gulf University focus on students’ ability to demonstrate pre-identified laboratory competencies and relate laboratory data with clinical scenarios. We conducted a questionnaire-based survey among undergraduates to know the preferences with respect to delivery methods for optimally facilitating learning for each laboratory session. Methods.

INTRODUCTION Apical periodontitis is a sequel to endodontic infection that causes inflammation and destruction of periradicular tissues (Nair, 2004). The microbiota of endodontic infection is comprised of heterogeneous polymicrobial communities (Jhajharia et al., 2015; Neelakantan et al., 2017) of different microorganisms, including fungi, archaea, viruses and bacteria.
