Oral Lymphatic Malformations: A 21-Year Retrospective Study in a Single Institution.

Introduction. Oral lymphatic malformations are uncommon lesions. This study assessed the clinicopathological and sociodemographic features of oral lymphatic malformations in a Brazilian oral pathology service. Methods. Between 2000 and 2021, all oral lymphatic malformations diagnosed in a single oral pathology service were selected for the study. Clinical data, such as age, sex, site of the lesion, clinical presentation, diagnosis clinical, and the type of biopsy were recorded from the patient's clinical charts. Results. From 7554 oral lesions, 17 (0.22%) were oral lymphatic malformations. This lesion similarly affected both sexes, and the mean age of the patients was 16.5 years. The tongue was the most common site (n = 13; 76%). The mean size of the lesions was 17 mm. Oral lymphatic malformations were asymptomatic for 29% of the patients. Clinically, most lesions appeared as a reddish, sessile nodule, with a pebbly surface. In addition, the clinical and histopathological diagnoses agreed for most lesions (n = 11; 64%). The type of biopsy performed was excisional in 41% of lesions. Conclusions. In summary, oral lymphatic malformations present a low prevalence among the oral lesions diagnosed in an oral pathology service. Moreover, they affect equally both sexes, especially young patients, and usually appear as an asymptomatic or symptomatic nodular swelling on the tongue.

Gingival neoplasms: a multicenter collaborative study of 888 patients in Brazil

Background: To evaluate the prevalence and clinicopathological features of a large series of gingival neoplasms in Brazil. Material and methods: All gingival benign and malignant neoplasms were retrieved from the records of six Oral Pathology Services in Brazil, during a 41-year period. Clinical and demographic data, clinical diagnosis, and histopathological data were collected from the patients' clinical charts. For statistical analysis, the chi-square, median test of independent samples and the U Mann-Whitney tests were used, considering a significance of 5%. Results: From 100,026 oral lesions, 888 (0.9%) were gingival neoplasms. There were 496 (55.9%) males, with a mean age of 54.2 years. Most cases (70.3%) were malignant neoplasms. Nodules (46.2%) and ulcers (38.9%) were the most common clinical appearance for benign and malignant neoplasms, respectively. Squamous cell carcinoma (55.6%) was the most common gingival neoplasm, followed by squamous cell papilloma (19.6%). In 69 (11.1%) malignant neoplasms, the lesions were clinically considered to be inflammatory or of infectious origin. Malignant neoplasms were more common in older men, appeared with larger size, and with a time of complaint shorter than benign neoplasms (p<0.001). Conclusions: Benign and malignant tumors may appear as nodules in gingival tissue. In addition, malignant neoplasms, especially squamous cell carcinoma, should be considered in the differential diagnosis of persistent single gingival ulcers. (AU)

Students' perception to an interactive web-based response system in oral and maxillofacial pathology teaching.

This study evaluated dental students' perceptions and adherence to an interactive web-based response system in the teaching of Oral and Maxillofacial Pathology. Between 2018 and 2019, students from a single Brazilian dental school used the Poll Everywhere® app to answer questions on subjects taught during an Oral and Maxillofacial Pathology course. At the end of the academic semester, the students completed a questionnaire containing 10 questions regarding the app's use. The study included 123 students. Regarding the devices used to answer the questions on the app, 117 (95.1%) students used a smartphone and 3 (2.4%) used a laptop. Almost all students (121; 98.4%) agreed that this interactive web-based response system provided the teacher with a better overview of students' understanding and improved their self-assessment of the acquired knowledge of the subjects. Most students (118; 95.9%) preferred classes using this technology and 122 (99.2%) stated that using the app made them feel more engaged in classes. In addition, all students agreed that the app improved student-teacher interactions. Most students (119; 96.7%) considered the digital interactive method more attractive than the conventional teaching approach, and 99 (80.5%) did not have any negative comments regarding the app. In conclusion, the Poll Everywhere® app provides a more dynamic and attractive educational environment for Oral and Maxillofacial Pathology teaching.

Avaliação do conhecimento de estudantes de odontologia sobre a transmissão e prevenção de infecções sexualmente transmissíveis / Assessment of odontology students' knowledge about the transmission and prevention of sexually transmitted infections

Objetivo: Conhecer o perfil demográfico e comportamento sexual e conhecimento clínico no que se refere à prevenção de IST dos estudantes do 4º ao 10º período do Curso de Odontologia de uma universidade brasileira. Métodos: Tratou-se de um estudo transversal, realizado através da aplicação de um questionário com perguntas sobre aspectos sociais, demográficos, econômicos e relativos às formas de transmissão e expressão clínica de IST. Os dados foram analisados descritivamente (médias, medianas, desvio padrão), assim como também foi realizada a análise estatística inferencial, com nível de significância de 5%. O programa utilizado para executar as inferências foi o SPSS, versão 23. Resultados: Constatou-se, preliminarmente, predominância de brancos entre os entrevistados, baixo uso de preservativos nas relações sexuais, altos índices de realização de teste para detecção de HIV e falhas no conhecimento em identificar IST passíveis de transmissão durante o atendimento odontológico. Conclusão: Há falhas no aprendizado do público-alvo da pesquisa, refletindo em desconhecimento sobre a prevenção, transmissão, sinais e sintomas de IST que envolvam a boca e seus anexos.

Aim:To know the demographic profile, sexual behavior, and clinical knowledge regarding STI prevention of students from the 4th to 10th period of the Dentistry Course at a Brazilian university. Methods: This was a cross-sectional study, carried out through the application of a questionnaire with questions about social, demographic, economic aspects and related to the transmission and clinical expression of STIs. Data were analyzed descriptively (means, medians, standard deviation), as well as inferential statistical analysis, with a significance level of 5%. The program used to perform the inferences was SPSS, version 23. Results: This study primarily found a predominance of whites among the interviewees, a low use of condoms in sexual relations, high rates of testing for HIV detection, and flaws in students' knowledge in identifying STIs capable of transmission during dental care. Conclusion: There are gaps in learning within the research target audience, reflecting a lack of knowledge about the prevention, transmission, signs, and symptoms of STIs involving the mouth and its attachments.

Awareness of patients receiving bisphosphonates: a cross-sectional study.

The aim of this study was to evaluate the awareness of patients using bisphosphonates (BP) regarding their risks and benefits. Sixty-five patients using BP were included. Each participant completed a self-administered questionnaire consisting of 13 questions, including sociodemographic and general information on BP. Data were analyzed using descriptive statistics, and a binomial test was used to assess patient knowledge about BP, considering a 5% significance level. Fifty-nine (90.2%) patients were unaware or had never heard of BP drugs and only 3 (4.6%) knew their indications. Only 6 patients (9.2%) said they knew about the oral complications caused by BP. Sixty-three patients (96.9%) said they were not referred to the dentist before starting BP treatment. Patients using BP do not have satisfactory knowledge regarding the risks and benefits of BP. Physicians and dentists must be prepared to inform and counsel BP users about their adverse effects and possible risk factors. Our results emphasize the importance of public policies, whether individual or collective, to be taken to increase knowledge about BP to avoid medication-related osteonecrosis of the jaw.

Oral epithelioid rhabdomyosarcoma: Report of a rare case and literature review of a distinct variant of rhabdomyosarcoma.

Epithelioid rhabdomyosarcoma is a new and rare morphological variant of rhabdomyosarcoma, with only a few reports in the literature. We aimed to describe an atypical case of this variant involving the oral cavity. A 33-year-old male patient presented with an asymptomatic, gingival mass adjacent to the left maxillary canine with progressive growth over approximately 3 months. Microscopic and immunohistochemical assessment of the biopsy specimen were consistent with epithelioid rhabdomyosarcoma. After initial chemotherapy and radiotherapy, the patient had a partial response. Surgical resection was performed, followed by adjuvant chemotherapy. After local and distant recurrences, the patient died 22 months after the initial diagnosis. According to the literature, epithelioid rhabdomyosarcoma still lacks data regarding its aetiologic factors and therapeutic options. Whether this tumour is a true subtype or simply a variant of other subtypes of rhabdomyosarcoma also remains unconfirmed. Final diagnosis leads to a broad array of microscopic and immunohistochemical analyses.

Identifying misconceptions about oral radiology and medicine among dental students.

PURPOSE/OBJECTIVES: Misconceptions are learning deficiencies that can lead to inappropriate clinical decision-making in dental practice. Although misconceptions are common among students, they are rarely analyzed in dental education. Thus, this study aimed to identify and analyze students' misconceptions about oral radiology and medicine at a Brazilian dental school. METHODS: Between October 2019 and March 2020, a self-administered anonymous questionnaire was distributed to dental students at the Federal University of Pernambuco, Brazil, which comprised multiple-choice questions about oral radiology and medicine. The questions were divided into two groups: 10 knowledge-based questions (less demand for reasoning) and five scenario-based questions (higher demand for reasoning). The students' responses were assessed for correctness (correct or incorrect) and confidence (sure or unsure), while misconceptions were identified when a student was sure of an incorrect response. Pearson's chi-square test was used to analyze the variables (α = 0.05). RESULTS: A total of 1380 responses were collected. Misconceptions represented 24.3% (n = 336) of the total responses and 56.8% of the incorrect responses. The mean misconceptions per student were 3.7 (range, 0-8). Students who chose incorrect answers tended to have higher confidence levels (p < 0.001). Moreover, misconceptions were more frequent for scenario-based questions (25.7%) than for knowledge-based questions (23.7%) (p = 0.000). CONCLUSION: A large number of misconceptions existed among participants. Our findings will aid educators and students in identifying misconceptions and planning measures to prevent and correct them.

Salivary gland cystadenocarcinoma: Rare neoplasm in buccal mucosa.

A 72-year-old female was referred for diagnosis of a lesion located in the right buccal mucosa, with duration unknown. At intraoral examination, the lesion appeared as a well-delimited, mobile, and submucosal nodule. A benign mesenchymal neoplasm was the main hypothesis of diagnosis. Histopathological analysis revealed salivary gland neoplasm formed by atypical cells often arranged in microcystic structures, with frequent intraluminal papillary projections. The tumor cells presented positivity for CK7 and negativity for CK20. Based on these features, the diagnosis of cystadenocarcinoma was established. The patient was submitted to wide surgical resection. No recurrence was observed after 48 months. Although rare, cystadenocarcinoma should be considered in the differential diagnosis of oral submucosal nodules.

Awareness on oral cancer among patients attending dental school clinics in Brazil

BACKGROUND: Oral cancer is considered a public health problem worldwide. Dental schools may play an important role in educating patients about oral cancer. This study aimed at evaluating the knowledge of patients attending clinics at two dental schools in Brazil. MATERIAL AND METHODS: From March 2017 to April 2017, 251 patients who were attending clinics at two dental schools in Recife, Brazil, were included in the study. Patients were contacted in the waiting rooms of the clinic. Each participant completed a self-administered questionnaire, which consists of 21 questions, including socio-demographic and specific information on the disease. Data were analyzed using descriptive statistics, and a chi-square test (with a 5% significance level) was used to assess the correlation between the variables, education and family income and other variables. RESULTS: Most participants were women (64.9%) with a mean age of 42.72 years. Most participants were knowl-edgeable about oral cancer and identified tobacco use (48.6%), alcohol consumption (25.1%), and solar radiation (12%) as the primary risk factors for the disease. Only 36.7% of the participants reported having received counsel-ling on oral cancer, of which 18.3% received the information from a dentist. All patients with an income higher than six minimum wages were aware about oral cancer (p = 0.001).CONCLUSIONS: These findings emphasize the importance of educational programs in dental schools as well provid-ing integrated services for patients seeking care at school clinics, including population's awareness on oral cancer

Neoplasias orofaciais em crianças e adolescentes / Orofacial neoplasms in children and adolescents

Objetivo:Este trabalho analisou os casos de neoplasias orofaciais em crianças e adolescentes, diagnosticadas pelo Laboratório de Patologia Oral da Universidade Federal de Pernambuco no período de março de 2000 a março de 2019. Métodos: Tratou-se de um estudo retrospectivo das neoplasias mais prevalentes diagnosticada no serviço. Os dados foram tabulados e analisados através do programa Statistical Package for the Social Sciences(SPSS) na versão 24.0. Resultados:Dos 6.766 casos diagnosticados, 101 foram de neoplasias, destes 52,5% foram no sexo feminino. A média de idade entre os pacientes foi de 12,6 anos. Em relação ao tipo de biópsia, a excisional foi mais prevalente e em 71,3% dos casos os diagnósticos histopatológicos confirmaram as hipóteses diagnósticas clínicas. A neoplasia benigna não odontogênica mais comum foi o papiloma oral com 30 casos (29,7%). Entre os tumores benignos de origem odontogênica, os odontomas foram os mais prevalentes com 16 casos (15,8%). Foram diagnosticados apenas dois tipos de neoplasias malignas: o carcinoma adenoide cístico e o leiomiossarcoma. Conclusão:Levantamentos epidemiológicos de lesões orofaciais são importantes para determinar a sua prevalência, além de contribuir com a determinação das características na população estudada, fornecendo ao cirurgião-dentista uma base sólida para o diagnóstico e manejo clínico das neoplasias nesses indivíduos.

Aim:To analyze the cases of orofacial neoplasms in children and adolescents, diagnosed by the Oral Pathology Laboratory of the Federal University of Pernambuco from March 2000 to March 2019. Methods: Treatment of a retrospective study of the most prevalent neoplasms diagnosed at the laboratory. Data were tabulated and analyzed using the Statistical Package for Social Sciences (SPSS), version 24.0. Results:Of the 6,766 cases diagnosed, 101 were neoplasms, 52.5% of these were not female. The average age among the patients was 12.6 years. Regarding the type of biopsy, tooth extractions were more prevalent, and in 71.3% of the cases, the histopathological diagnoses confirmed the clinical diagnostic hypotheses. The most common non-odontogenic benign neoplasm was the oral papilloma, found in 30 cases (29.7%). Among the benign tumors of odontogenic origin, the odontomas were the most prevalent in 16 cases (15.8%). Only two types of malignant neoplasms were diagnosed: adenoid cystic carcinoma and leiomyosarcoma. Conclusion:Epidemiological surveys of orofacial lesions are important to determine their prevalence and aid in defining the characteristics in the studied population, providing the dentist with a continuous basis for the diagnosis and clinical treatment of neoplasms in these individuals.

Oral paracoccidioidomycosis in a non-endemic region from Brazil: A short case series.

BACKGROUND: Although the paracoccidioidomycosis (PCM) is endemic in Brazil, the occurrence in most states from the North and Northeastern Brazil is very unusual. The aim of this study was to evaluate the clinicopathologic features of a case series of oral PCM in a non-endemic region from Brazil (Northeastern region), discussing the clinical and histopathological differential diagnoses of the oral manifestations of the disease. MATERIAL AND METHODS: Between 2000 and 2017, all cases of oral PCM were retrieved from the Oral Pathology Laboratory, Universidade Federal de Pernambuco, located at Northeastern Brazil. Clinical data, such as age, gender, origin, occupation, site, symptoms, time of complaints, clinical presentation, number of lesions, and clinical hypotheses of diagnosis, were collected from the clinical charts. All cases were histologically reviewed in hematoxylin-eosin and Gomori-Grocott staining. RESULTS: Six cases were identified. All patients were male, with a mean age of 53.8 years (ranging from 40 to 73 years). Four cases appeared as multiple ulcers and two presented single lesions (buccal mucosa and hard palate). Clinically, in five cases, squamous cell carcinoma was considered in the differential diagnosis. The common histopathological features consisted of hyperplastic epithelium, intraepithelial microabscesses, and formation of granulomatous chronic inflammatory reaction in a fibrous connective tissue with severe chronic inflammatory reaction. Yeasts were observed either inside of multinucleated giant cells or extracellularly. CONCLUSIONS: Although rare in non-endemic regions, oral PCM should be considered in the differential diagnosis of oral chronic ulcers, mainly those multiple. Key words:Oral mucosa, mycology, paracoccidoidomycosis, ulcer.

Histopathological Findings of Intraoral Pleomorphic Adenomas: A Retrospective Study of a Case Series.

The aim of this study was to describe the clinicopathological features of 21 cases of intraoral pleomorphic adenoma (PA), with emphasis on histopathological findings. Between 2000 and 2016, all patients diagnosed as intraoral PA were retrieved and histopathological slides stained with hematoxylin and eosin reviewed to confirm the diagnosis. All tumors were classified histologically according to Seifert et al (1980). The clinical and histopathological variables were analyzed using the Fisher's exact test, considering a significance level of 5% (P < .05). Plasmacytoid (85.7%), spindle (38.1%), and epithelioid (9.5%) myoepithelial cells were observed. Oncocytic (47.6%) and mucous (19%) cells were also found. The stroma was predominantly fibrous (95.2%), followed by myxoid (66.7%), hyaline (61.9%), and chondromyxoid (33.3%). Squamous (57.1%), adipose (47.6%), sebaceous (14.3%), and bone (14.3%) differentiations were found. Additionally, a group of tumors presented pleomorphism (23.8%), mitoses (14.3%), capsule infiltration (9.5%), and necrosis. The presence of cystic structures occurred significantly in patients older than 30 years (P = .04) and mitoses were more observed in PA from buccal mucosa (P = .026). All cases that presented plasmacytoid cells were smaller than 1.5 cm (P = .015). All tumors with up to 50% stroma area presented with size smaller than 2.0 cm (P = .013). Intraoral PA presents a large morphological spectrum and several microscopic features are associated with clinical findings.

Intraoral lipomas: A clinicopathological study of 43 cases, including four cases of spindle cell/pleomorphic subtype

Background: The aim of this study was to describe the clinicopathological characteristics of 43 intraoral lipomas and classify them according to their microscopic variants. Material and Methods: All the cases of intraoral lipomas diagnosed at an Oral Pathology service were selected for the study. Clinical data, such as age, gender, location, time of evolution, clinical presentation, clinical hypothesis of diagnosis, and treatment, were collected from the clinical files. Results: Of the 43 cases analyzed, 24 (55.8%) occurred in women. The mean age was 77.4 years. The most affected site was the buccal mucosa (22 cases, 51.1%). The mean lesion size was 1.7 cm. Twenty-three cases (53.5%) were classified as simple lipoma, 14 (32.6%) as fibrolipoma, four (9.3%) as spindle cell/pleomorphic lipoma (SC/PL), one (2.3%) as lipoma of the salivary glands, and one (2.3%) as intramuscular lipoma. In one case of SC/PLs, lipoblasts were observed. No atypical lipoblasts or mitoses were noted. Lipoma was considered more often than other tumor histological subtypes among the clinical hypotheses of diagnosis when the final diagnosis was simple lipoma (p = 0.01). Conclusions: Intraoral lipomas present different clinical presentation depending on the histological subtype. In SC/PLs, lipoblasts with vacuolated cytoplasm may be found and the presence of mature adipocytes is essential for diagnosis

Opinião de cirurgiões dentistas sobre atividades de preceptoria na formação de estudantes de Odontologia de uma universidade brasileira / Dentists' opinion about preceptory activity in the training of Dentistry students from a Brazilian university

O objetivo deste estudo foi conhecer a opinião de cirurgiões-dentistas sobre a atividade de preceptoria desempenhada por eles nos estágios curriculares 1, 2 e 3 do curso de Odontologia da Universidade Federal de Pernambuco, realizados em unidades da Atenção Básica à Saúde no município de Recife. Realizou-se estudo descritivo e de abordagem quantitativa. De um universo de 36 cirurgiões-dentistas foram incluídos aqueles com no mínimo um ano de experiência como preceptor. Para a coleta de dados utilizou-se formulário de entrevista semiestruturada,submetido à validação de face e aplicado face a face. Todos os 26 preceptores que atenderam ao critério de inclusão foram entrevistados, sendo 80,8% mulheres; 92,3% com vínculo de trabalho efetivo; 96,2% pós-graduados, sendo 80,2% deles especialistas em Saúde da Família. Apenas 15,4% recebiam incentivos para preceptoria, mas não estavam satisfeitos; 11,2% receberam formação em preceptoria; 92,3% demandaram capacitação para exercê-la; 69,2% atuaram nos três tipos de estágios. Prevaleceu (76,3%) a preferência por atuar no estágio 3 (clínico) do que nos dois outros (extraclínicos). Para 65,3% deles a estrutura física e organizacional para exercer a preceptoria é ruim, 69,2% avaliaram como insatisfatório o apoio institucional do serviço e 57,7% o da universidade, apesar dos esforços da instituição formadora em promover educação permanente e presencial nos serviços. Os pontos positivos mais citados foram a troca de saberes com os estudantes e docentes e a importância de integrar o estudante ao Sistema Único de Saúde. Conclui-se que embora valorizem a preceptoria, prevaleceram insatisfações de ordem trabalhista, de condições de trabalho e de formação que precisam ser enfrentadas (AU).

This study aimed to know the opinion of dentists on the preceptorship activities performed in the dental curricular internships 1, 2 and 3 of Federal University of Pernambuco, carried out in units of basic attention to health in the city of Recife. Descriptive study and quantitative approach were carried out. From a universe of 36 dentists, were included those with at least one year of experience as preceptor. For the collection of data used A semi-structured interview, subjected to face validation and applied face to face, was used for data collection. All 26 preceptors who obeyed the inclusion criterion were interviewed, being 80.8% women; 92.3% with effective work link; 96.2% graduate, being 80.2% of them family health specialists. Only 15.4% received incentives for preceptorship, but they were not satisfied; 11.2% received training in preceptorship; 92.3% were trained to exercise it; 69.2% acted in the three types of internships. It prevailed (76.3%) the preference for acting in Stage 3 (clinical) than in the two others (nonclinical). According to 65.3% of the interviewed, physical and organizational structure to exercise the preceptorship is bad, 69.2% evaluated the institutional support of the service as unsatisfactory and 57.7% of the university, despite the efforts of training institution in promoting permanent education and presence in services. The most cited positive points were the exchange of knowing with the students and faculty, and the importance of integrating the student into the unique health system. It is concluded that although they value the governess, they have prevailed dissatisfactions of labor order, working conditions and training that need to be addressed (AU).

Oral squamous cell carcinoma: a clinicopathological study on 194 cases in northeastern Brazil. A cross-sectional retrospective study.

BACKGROUND: Only a few studies have evaluated the clinicopathological features of oral squamous cell carcinoma (SCC) in Brazil, and most were conducted in the most industrialized region of the country, i.e. the southeastern region. The aim of this study was to evaluate the clinicopathological features of this malignant neoplasm in northeastern Brazil. DESIGN AND SETTING: Retrospective study performed in an oral pathology laboratory in Recife, Brazil. METHODS: All cases of oral SCC that occurred between 2000 and 2015 were studied. Clinical data were recorded and histological slides were reviewed. Statistical analysis was performed using the chi-square test (P ≤ 0.05). RESULTS: A total of 194 cases were evaluated. The male-to-female ratio was 1.5:1. The mean age was 65.4 years, and only 6.6% of the cases occurred in patients younger than 41 years. Most tumors consisted of well-differentiated SCC (54.6%). CONCLUSIONS: The findings of this study highlight the higher prevalence of oral SCC among women and the increasing number of cases among young patients. Thus there is no specific risk group for oral SCC, as in the past. This fact needs to be taken into consideration in clinical routine care, so that apparently innocuous malignant lesions do not go unnoticed in these individuals.
