Special Issue Information

Dear Colleagues,

This Special Issue is the continuation of our previous special issue "Microbiology of Oral Diseases".

The composition and activities of the oral microbiome play a foundational role in health and disease within the oral cavity and beyond. This Special Issue is dedicated to the breadth of research focusing on how variables such as microbial properties, host genetics, cell biology, and immunology interact with environmental influences to maintain or disrupt the healthy balance between the host and resident microflora in oral.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Until recently, bacterial species were the primary etiological factor of periodontal disease, but recent studies have shown that their effective removal from tooth surfaces does not necessarily prevent the progression of the disease. A logical hypothesis leads to the conclusion that various etiological factors contribute to the etiopathogenesis of this disease. Recent evidence also indicates protozoa as potential pathogens. In this review, the role of Entamoeba gingivalis, Acanthamoeba spp., and Trichomonas tenax in periodontal disease was analyzed, and the various aspects of the role of protozoa in the etiopathogenesis of periodontal disease, the bacterial–protozoa model of the disease, and the therapeutic implications were categorized. The multifactorial nature of periodontal disorders requires further research to better identify individuals at risk and prescribe earlier and more definitive treatments. The evidence supporting the role of protozoa in periodontal disease is compelling. These organisms are essential contributors to this complex disease. The key to developing more effective prevention and treatment strategies lies in understanding the intricate interactions between protozoa, bacteria, and the host. A better understanding of the protozoa aspect of periodontal disease progression could significantly change the future perspective of diagnosing, preventing, and treating periodontal disease.

Dental caries is a significant oral and public health problem worldwide, especially in low-income populations. The risk of dental caries increases with frequent intake of dietary carbohydrates, including sugars, leading to increased acidity and disruption of the symbiotic diverse and complex microbial community of health. Excess acid production leads to a dysbiotic shift in the bacterial biofilm composition, demineralization of tooth structure, and cavities. Highly acidic and acid-tolerant species associated with caries include Streptococcus mutans, Lactobacillus, Actinomyces, Bifidobacterium, and Scardovia species. The differences in microbiotas depend on tooth site, extent of carious lesions, and rate of disease progression. Metagenomics and metatranscriptomics not only reveal the structure and genetic potential of the caries-associated microbiome, but, more importantly, capture the genetic makeup of the metabolically active microbiome in lesion sites. Due to its multifactorial nature, caries has been difficult to prevent. The use of topical fluoride has had a significant impact on reducing caries in clinical settings, but the approach is costly; the results are less sustainable for high-caries-risk individuals, especially children. Developing treatment regimens that specifically target S. mutans and other acidogenic bacteria, such as using nanoparticles, show promise in altering the cariogenic microbiome, thereby combatting the disease.
