Abstract

The human oral cavity is a major point of entry for microorganisms, many of which live and multiply in the mouth. In addition, it provides an accessible site for sampling compared to other parts of the body; however, caution should be taken during oral sampling as many factors contribute to the microbial diversity in a site-dependent manner. The accessibility of the oral cavity and its microbial diversity emphasize the crucial need to avoid cross-contamination during the sampling procedure. In this chapter, we describe various detailed oral sampling procedures. These methods include supragingival dental plaque sampling, subgingival dental plaque sampling, oral mucosal sampling, and endodontic sampling methods for extracted teeth or in the patient's mouth. The proposed protocols provide tips to avoid contamination between different oral sources of bacteria and possible alternatives to the tools used.

Keywords: Endodontic sample; Microbiome; Oral cavity; Oral mucosal sample; Oral sampling; Sampling; Subgingival plaque; Supragingival plaque; Teeth.
