Objective: This study aimed to analyze the clinical characteristics of salivary gland lesions diag-nosed in an Oral Medicine center in Brazil from 2010 to 2019. Material and Methods: The files describing all cases classified as salivary glands lesions at the Stomatology of the Polyclinic Pi-quet Carneiro of the State University of Rio de Janeiro from 2010 to 2019 (a 10-year period) were reviewed for the purposes of this study. Data were tabulated and analyzed descriptively and comparatively using Pearson's Chi-Square Test and Fisher's Exact Test using the Graph Pad Prism program (Version 6.07 by Windows, San Diego, California, USA), with a significance lev-el of 5% (p<0.05). Results: The analysis of 2,134 medical records - 166 (7.78%) presented with salivary glands lesions in which 117 were women (70.48%) and 49 men (29.52%); the mean age of patients was 39.30; the most common clinical lesion of the salivary glands observed was mu-cocele representing 59 cases (35.54%), followed by sialadenitis with 33 cases (19.88%). Conclu-sions: According to all data gathered in this work, we concluded that the salivary gland lesions show a low prevalence and affect more white female patients in the sixth decade of life.

Objective: to evaluate by means of electromyographic analysis of the masseter and suprahyoid muscles the oral phase of the swallowing of different volumes of saliva and liquid in healthy adult individuals. Material and Methods: the method consisted in analyzing samples of three swallowing trials: voluntary and single swallow of saliva (dry), voluntary and single swallow of 10 ml of water, and voluntary and single swallow of 20ml of water. Statistical analysis: Through Friedman’s ANOVA test we observed a significant variation in the medium potential of the right suprahyoid muscle (p=0.010) when compared to the left suprahyoid muscle (p=0.05). Other correlations were verified by using the Nemenyi test, the Wilcoxon test and the Spearman coefficient to support the different analyses of the results. Results: the analysis found a direct relation between the electrical activity of the masseter and suprahyoid muscles when swallowing 20 ml water as regards the highest potential values, irrespective of face side – left or right; i.e., when swallowing 20ml water, the higher the potential of one muscle group, the higher the expected value of its antagonist. Conclusion: the electromyographic behavior of the masseter and suprahyoid muscles during voluntary swallowing of saliva and two standardized liquid volumes showed that the electrical activity of the masseter muscles did not vary according to the type of swallowing.

Objective: the aim of this paper was to verify knowledgement senior undergraduate dental students’ of Rio de Janeiro Universities on how to proceed when facing violence against women. Material and Methods: a cross-sectional study was conducted, using an on-line Google Form containing 17 objective questions. Last year undergraduate dental students from Rio de Janeiro metropolitan area and close campi answered the survey, coming to a total of 237 answers, with 95% confiability. This research was approved by the number 4.105.142 CEP-HUFF/UFRJ technical report. Results: only 26,6% of the students claimed to have received orientation on how to conduct a case of violence against women. Moreover, 67,1% don’t feel ready to guide victims of domestic violence, claiming to have none/phew/insufficient knowledge of the topic. Most of the students, 92,4%, said that they didn’t receive any information about the notification and grievances file and, 76,7% of those that did, said that they wouldn’t be able to fill it. Over 71% know a woman who has been a victim of domestic violence, who were mostly hit on head/neck/face. The undergraduate students reported that they would provide dental care, orientate the victim and report the domestic violence scenario to the responsible entities. Conclusion: thus, it was observed a knowledge deficit concerning violence against women protocols in undergraduate dentistry courses in Rio de Janeiro, since this topic isn’t approached or is taught using inefficient methods

Objective: To compare the anesthetic efficacy of 4% articaine associated with epinephrine concentrations of 1:100,000 and 1:200,000, using the infraorbital nerve block approach. Material and Methods: This is a double-blind cross-sectional study conducted with 40 volunteers. Pulpal anesthetic parameters such as latency, duration, and success rates were evaluated using a pulp tester device, which emits electrical discharges ranging from 0 to 80 ?A in 20 seconds. Soft tissue anesthesia (vestibular gum) was evaluated by pressing a wooden toothpick into the gingival region used in the approach. Finally, parameters related to pain after anesthesia were evaluated. Results: We found no statistically significant differences between anesthetic solutions for pulp and soft tissue regarding latency period. The anesthetic solution containing 1:100,000 epinephrine presented a significantly longer effect duration than 1:200,000 epinephrine regarding pulpal anesthesia of maxillary central incisors, first maxillary premolar, and second maxillary premolar. As for vestibular gum, we found no statistically significant differences between the solutions. Regarding pain at injection, the two anesthetic solutions showed no statistically significant differences. Conclusion: 4% articaine with 1:100,000 epinephrine presented significantly longer pulpal anesthesia duration in some dental elements when compared to 1:200,000 epinephrine

Objective: to describe different in vivo and in vitro experimental models and summarize evidence that proposes molecular mechanisms or demonstrate a cause and effect correlation between periodontal disease (PD) and oral squamous cell carcinoma development. Material and Methods: a Literature search of various electronic databases (Medline, SCOPUS, Web of Science) using appropriate keywords (e.g., periodontal disease, periodontitis, squamous cell carcinoma, oral cancer, transformation, carcinogenesis, mouth neoplasms, and carcinoma) was performed. Then, a comprehensive literature review of the current understanding of this link was elaborated. Results: the experimental data suggest that PD induces initiation, promotion, and oral squamous cell carcinoma progression. Periodontal disease models here revised demonstrate a direct relation to carcinogenesis and propose several possible molecular mechanisms of action, such as via activation of Toll-like receptors (TLRs), activation of transcription 3 activator (STAT3) and Notch1 pathways and increased interleukin-6 (IL-6), TNF-?, TGF-?1, cyclin D1, metalloproteinase matrix-9 (MMP-9) and heparinase production as well as regulating the host immune response and induce epithelial-mesenchymal transition (EMT). Conclusion: the use of in vivo and in vitro studies is very significant for understanding the casual association of these biological processes. The current findings highlight the importance of further studies in this area to understand the cause and effect relationship of these pathologies and the development of new strategies for the prevention and treatment of this type of cancer
目的:描述不同的体内和体外实验模型，总结提出牙周病(PD)与口腔鳞状细胞癌发展之间的分子机制或因果关系的证据。材料和方法:使用适当的关键词(如牙周病、牙周炎、鳞状细胞癌、口腔癌、转化、癌变、口腔肿瘤、癌)对各种电子数据库(Medline、SCOPUS、Web of Science)进行文献检索。然后，对目前对这一环节的认识进行了全面的文献综述。结果:实验数据表明PD诱导口腔鳞状细胞癌的发生、促进和进展。本文修订的牙周病模型证明了与癌变的直接关系，并提出了几种可能的分子作用机制，如通过激活toll样受体(TLRs)、激活转录3激活因子(STAT3)和Notch1途径以及增加白细胞介素-6 (IL-6)、TNF-?TGF - ?1、细胞周期蛋白D1、金属蛋白酶基质-9 (MMP-9)和肝素酶的产生，以及调节宿主免疫反应和诱导上皮-间质转化(EMT)。结论:使用体内和体外研究对了解这些生物过程的偶然关联非常重要。目前的研究结果强调了在这一领域进一步研究的重要性，以了解这些病理的因果关系，并制定预防和治疗这类癌症的新策略

Objective: This study aimed to review the literature on chitosan antibacterial activity against Streptococcus mutans, assessing this biopolymer’s potential for caries control and prevention. Materials and Methods: A search for studies in the “Pubmed” database was carried out, using the terms “Chitosan and Streptococcus mutans.” Eightyeight articles were found, and no filter was used in the search. Results: In general, chitosan inhibited the adhesion and biofilm of Streptococcus mutans, tested in different concentrations, exposure time, molecular weight, and pH. Therefore, chitosan has antibacterial activity against Streptococcus mutans. Conclusion: Although it can demonstrate the potential for use as a component of an oral product, more studies need to be conducted and analyzed to prove its ability to prevent and control dental caries

Objective: To demonstrate a surgical treatment of a large infected root cyst associated with the upper lateral incisor through a case report. Case Report: Patient reported a major complaint of swelling in the palatal region that was present for 6 months. The patient was submitted to non-surgical endodontic treatment. After clinical and radiographic examinations, decompression marsupialization was performed to create a window on the buccal cortical wall and an acrylic resin drain was installed in the depth of the cystic cavity. Two months later, a procedure was planned with cystectomy and apicoectomy on tooth 12, enucleated cyst, bone graft and barrier with purified collagen sponge. After enucleation, a sample of the cystic capsule was examined histologically and the diagnosis of periapical cyst was confirmed. Conclusion: After 1-year, clinical cicatrization and radiographic resolution of the maxillary radiolucency were verified and the patient did not present painful symptoms, demonstrating the success of the treatment performed
