Objectives.: To evaluate the antimicrobial activity of Myrciaria dubia on oral microorganisms., Materials and Methods.: A systematic review of the literature following PRISMA guidelines was conducted through searches of studies published between 2008 and 2018 in Pubmed, LILACS, SciELO, ProQuest, EBSCO, and Google Scholar., Results.: Eleven (11) in vitro studies were gathered; all the studies showed positive antimicrobial activity on gram-positives, mainly by each of the parts of its fruits. However, such activity compared to chlorhexidine in only two studies, and, in another study, it was better than an antibiotic. A high risk of bias was detected in most studies. Phenolic compounds, including polyphenols and acylphloroglucinols, were identified as responsible for its activity., Conclusions.: There is evidence of antimicrobial activity in M. dubia. Its study as an antimicrobial against oral microorganisms is still incipient, but there is great potential thanks to the potent phytochemicals it contains. Also, additional quality studies are required: comparing their activity versus oral antiseptics and on microorganisms associated with dental caries and periodontal disease.

Our aim is to contribute to the rational use of antibiotics prescribed by family doctors when a patient consults for a dental problem. Nowadays we should not ask which antibiotic to give. The question has to be if we need to prescribe antibiotics in front of the most common odontogenic infections seen in our practice. We review the main dental infections, which should be their appropriate management and the role of prevention. We need to know the complexity of the oral microbiome because it?ll depend on the appropriateness of the antibiotherapy, the evolution towards cure or progression of some odontogenic infections. The bacterial plaque, formed by the biofilm, behaves as a barrier to the action of antimicrobials. It?s in the prevention of its development as well as in it mechanical elimination once shaped, in what the family doctor should insist. We must transmit antibiotics don?t heal dental pain., (Copyright © 2017 Elsevier España, S.L.U. All rights reserved.)

Aiming to draw the current world outlook of the caries-forming process, pertinent information was compiled from the World Health Organization and various other sources. Data from the different countries were grouped in five categories, depending on the average number of teeth affected. On the basis of compiled data and the experience of countries enjoying the highest levels of buccal health, a set of tactics are proposed toward diminishing the incidence of cavities in our country.
