Final answer:
The research does not specify a singular action dentists are most likely to perform, but implies they engage in practices such as recommending flossing, managing infections, and using amalgams for fillings.
Step-by-step explanation:
The research presented does not specify a singular action that dentists are most likely to perform, as the reported information covers various aspects of dental practice and historical progress, as well as general health issues. Nonetheless, based on the context provided by the excerpts such as discussions around gum disease, infections, and medical record analysis, one might infer dentists are likely to recommend regular flossing, manage infection risks, and conduct thorough patient examinations and interviews. Moreover, dentists often use amalgams for fillings due to their durability and cost-effectiveness, despite contemporary concerns over mercury content.
