“…The strain of SRB Desulfovibrio isolated from the oral cavity of an orthodontic patient from a previous study by the author [ 9 ] was used as the strain for this in vitro study. In this study [ 6 ], DNA amplification based on universal 16S rRNA and subsequent sequencing confirmed the presence of SRB specific to D. desulfuricans , D. piger , and D. fairfieldensis based on the identification in the existing database at GenBank.…”

Aim: Orthodontic literature is scant when it comes to microbial corrosion. The oral prevalence of many bacteria which are capable of causing microbial corrosion is reported in the dental literature. The aim of this study is to experimentally determine the corrosive potential of an oral strain of Sulfate-reducing bacteria. Materials and Methods: Stainless steel (SS) bracket, stainless steel archwire, NiTi archwire, Titanium molybdenum (TMA) archwire, and titanium miniscrew were immersed in five media which included Artificial saliva (group I), Sulfate rich artificial saliva (group II), API agar medium specific for SRB (group III), AS + API medium+ bacterial strain (group IV), SRAS+ API medium+ bacterial strain (group V). The materials were then subjected to Scanning electron microscopy and energy-dispersive X-ray analysis (EDX). Results: Materials in groups I, II, and III did not show any surface changes whereas materials in groups IV and V which contained the bacteria showed surface changes which were erosive patches suggestive of corrosion. EDX analyses were in line with similar findings. Conclusion: This in vitro study suggested that the oral strain of Sulfate-reducing bacteria was able to induce corrosive changes in the experimental setup.

“…The subgingival microbiota corresponds to diverse microbial communities (bacteria, archaea, fungi and viruses) that live attached to the root surface of teeth or dental implants with their outer surface in contact with the gingival tissue [ 64 , 65 ]. Bacteria are the most abundant component, and it is estimated that there are approximately 500 species that live in a state of eubiosis with the host [ 66 , 67 , 68 ].…”

The success of a prosthetic treatment is closely related to the periodontal health of the individual. The aim of this article was to review and present the importance of prosthetic restorative materials on the condition of the periodontium, the changes that occur in the composition of the subgingival microbiota and the levels of inflammatory markers in gingival crevicular fluid. Articles on the influence of different prosthetic restorative materials on subgingival microbiota and proinflammatory cytokines were searched for using the keywords “prosthetic biomaterials”, “fixed prosthesis”, “periodontal health”, “subgingival microbiota”, “periodontal biomarkers” and “gingival crevicular fluid” in PubMed/Medline, Science Direct, Scopus and Google Scholar. The type of material used for prosthesis fabrication together with poor marginal and internal fit can result in changes in the composition of the subgingival microbiota, as well as increased accumulation and retention of dentobacterial plaque, thus favoring the development of periodontal disease and prosthetic treatment failure. Biological markers have helped to understand the inflammatory response of different prosthetic materials on periodontal tissues with the main purpose of improving their clinical application in patients who need them. Metal-free ceramic prostheses induce a lower inflammatory response regardless of the fabrication method; however, the use of CAD/CAM systems is recommended for their fabrication. In addition, it is presumed that metal-ceramic prostheses cause changes in the composition of the subgingival microbiota producing a more dysbiotic biofilm with a higher prevalence of periodontopathogenic bacteria, which may further favor periodontal deterioration.

“…Some of them can even be life-threatening. The local and systemic factors determining the microbiota and genetics, as well as the individual factors such as diet, teeth brushing habits, dentures, dental procedures, mouthwashes, medications, etc., can be involved in the occurrence of orofacial infections [ 1 , 3 , 4 , 5 , 6 , 7 ]. Oral infections can occur under certain conditions, such as poor oral hygiene, antibiotic consumption, trauma, and dry mouth, and can damage the oral cavity.…”

Undoubtedly, diagnosing and managing infections is one of the most challenging issues for orofacial clinicians. As a result of the diversity of symptoms, complicated behavior, and sometimes confusing nature of these conditions, it has become increasingly difficult to diagnose and treat them. It also highlights the need to gain a deeper insight into the orofacial microbiome as we try to improve our understanding of it. In addition to changes in patients’ lifestyles, such as changes in diet, smoking habits, sexual practices, immunosuppressive conditions, and occupational exposures, there have been changes in patients’ lifestyles that complicate the issue. Recent years have seen the development of new infection treatments due to the increased knowledge about the biology and physiology of infections. This review aimed to provide a comprehensive overview of the types of infections in the mouth, including the types that viruses, fungi, or bacteria may cause. It is important to note that we searched the published literature in the Scopus, Medline, Google Scholar, and Cochran databases from 2010 to 2021 using the following keywords: “Orofacial/Oral Infections,” “Viral/Fungal/Bacterial Infections”, “Oral Microbiota” And “Oral Microflora” without limiting our search to languages and study designs. According to the evidence, the most common infections in the clinic include herpes simplex virus, human papillomavirus, Candida albicans, Aspergillus, Actinomycosis, and Streptococcus mutans. The purpose of this study is to review the new findings on characteristics, epidemiology, risk factors, clinical manifestations, diagnosis, and new treatment for these types of infectious diseases.
