Objective
To report the clinicopathologic features of acquired oral syphilis cases in South American countries.
Materials and Methods
Clinical data were retrospectively collected from the records of 18 oral diagnostic services in Argentina, Brazil, Chile, Colombia, Venezuela, Uruguay, and Peru. Serologies of nontreponemal and treponemal tests were used for diagnosis.
Results
The series comprised 339 cases of acquired oral syphilis. Secondary syphilis ranked as the most common stage (86.7%). Lesions were more frequent among males (58.0%) and young adults with a mean age of 33.3 years. Individuals aged 20–29 years were most affected (35.3%). The most commonly involved sites were the tongue (31.6%), lip/labial commissure (25.1%), and hard/soft palate (20.4%). Clinically, acquired oral syphilis usually presented as mucous patches (28.4%), papules (25.7%), and ulcers (18.1%). Skin manifestations occurred in 67.7% of individuals, while lymphadenopathy and fever were observed in 61.3% and 11.6% of all subjects, respectively. Most patients were treated with the benzathine penicillin G antibiotic.
Conclusion
This report validates the spread of acquired oral syphilis infection among young adults in South America. Our directives include accessible diagnostic tools for proper disease screening, surveillance, and counselling of affected individuals, especially in low‐ and middle‐income countries.
Background
Alveolar Osteitis (AO) is one of the most common complications of tooth extraction. Several therapeutic interventions have been described for the treatment of AO, however, there are no treatment standardized protocols. The aim of this study was to conduct a systematic review on the efficacy in pain control of the different treatments for AO. The feasibility of the application of these interventions is also discussed.
Material and Methods
A structured electronic and hand search strategy was applied to PubMed, Scopus, Cochrane Library, OpenGrey, and Google Scholar between January 2010 and July 2020 to identify studies according to PRISMA guidelines. The inclusion criteria were original English and Spanish clinical trials that analyzed pain-control parameters according to visual analog scale (VAS, 0-10 scale), or pain relief patients’ percentages. Those treatments that reach VAS ≤ 4 on day 2 or before; or ≥ 85% of patients with absence of pain symptoms at day 7 or before were considered accepTable for their recommendation.
Results
The final review included 17 clinical trials. Among them, there were analyzed a total of 39 different AO treatments. 53,8% of the treatments fulfill the proposed parameters for pain control.
Conclusions
Treatment alternatives are multiple, heterogeneous, and difficult to compare. The management of AO is summarized in basic (intra-alveolar irrigation) and specific procedures (Alveogyl®, Neocones®, SaliCept Patch®, Low-Level Laser, Platelet-Rich Fibrin) that reach pain control success. They could be selected according to their availability and advantages or disadvantages.

Background
Multiple white plaques of the oral mucosa are usually associated with potentially malignant disorders such as oral lichen planus, oral lichenoid lesions and proliferative verrucous leukoplakia. Previous studies in the current literature describe a potential clinical overlap in these entities. The aim of this study is to review clinicopathological and evolutive features of these Oral Potentially Malignant Disorders highlighting the dynamic changes of diagnoses.
Discussion
It was previously hypothesized that a subset of patients with oral lichen planus or oral lichenoid diagnosis, could develop multiple white plaques during the natural history of the disease, fulfilling diagnostic criteria for proliferative verrucous leukoplakia. Consequently, these entities could, under certain conditions, obey a continuum of the same precancerous condition in the context of the field cancerization theory, increasing the risk of malignant transformation. Nevertheless, there is limited scientific evidence concerning this issue.
Conclusion
Further studies are needed to understand the biological and evolutive features of the link between these oral potentially malignant disorders. Regardless of its diagnosis, these patients with multifocal white lesions must be carefully monitored to detect early malignant transformation.
There are similarities between the clinical conditions associated with genital and oral mucosal human papillomavirus (HPV). The role of HPV infection in oral carcinogenesis is currently controversial. Also, factors underlying this infection are still unclear. The frequent location of HPV lesions in areas of trauma indicates the role of mechanical irritation as a necessary event for the penetration and/or reactivation of the virus into the epithelium. Oral mucosa is frequently exposed to mechanical irritation, as it is in constant and intimate association with hard tissues. During the oral HPV infection, favorable conditions must be generated for the infection to be successful. Some of them, associated with proliferation of basal keratinocytes, are related to the presence of external stimuli, such as chronic mechanical irritation (CMI). The objective of this work is to demonstrate, through the presentation of three clinical cases, the possible role of CMI in the pathophysiology of HPV lesions of the oral mucosa.
