Evaluation of Mandibular Bone Microstructure in CT Scans of People with Sickle Cell Disease.

OBJECTIVE: Sickle cell disease (SCD) is a common inherited disease, and is characterized by a genetic modification that determines the production of a hemoglobin with altered morphology. This anatomical change of hemoglobin leads to vaso-occlusive disorders and premature hemolysis of the cell, causing chronic anemia and bone marrow hyperplasia due to increased hematopoietic demand. As a consequence, several skeletal changes are reported in the skull, spine, ribs, pelvis, femur, and metatarsals. In the craniofacial region, dentofacial deformities are described, especially maxillary protrusion. However, studies evaluating bone microarchitecture are scarce. The aim of this study is to evaluate the mandibular bone microstructure of people with SCD on computed tomography (CT) scans. MATERIALS AND METHODS: Morphometric parameters were analyzed on CT scans of the mandible of people with SCD and people without this disease or any other disease affecting bone metabolism, matched for sex and age. STATISTICAL ANALYSIS: The results were compared by Student's t-test for paired samples and for an error probability of 5%. RESULTS: This study demonstrated that the mandibular bone of people with SCD presents significantly less number, connectivity and thickness of bone trabeculae, as well as having a lower fractal dimension and greater porosity. CONCLUSION: Mandibular bone of people with SCD has lower bone density and more widely spaced trabeculae.

Evaluation of Antibiotic Prophylaxis Prescriptions for Infectious Endocarditis Before Oral Procedures Between Cardiologists and Dentists

Abstract Background Infective endocarditis (IE) is a serious disease with a high mortality rate. Antibiotic prophylaxis for bacterial endocarditis before invasive procedures has been recommended in patients with predisposing cardiac conditions since 1960, but contemporary guidelines worldwide have proposed changes. Objective To evaluate the knowledge and pattern of prescription by cardiologists and dentists regarding antibiotic prophylaxis for bacterial endocarditis before risky oral procedures. Methods This is an observational and cross-sectional study. Data were obtained from an online questionnaire, sent to cardiologists and dentists linked to specialty societies, in the first semester of 2021. Data analysis was performed using descriptive statistics, and comparisons between variables were done in an exploratory approach. The significance level adopted was 5%. Results From 613 responders, 82.5% of cardiologists and 79.5% of dentists reported prescribing antibiotic prophylaxis for patients at high and moderate risk for IE. Of dental procedures capable of generating bacteremia, all were correctly identified by more than 50.0% of the sample. As for the habits of daily living, flossing and toothbrushing had almost 50.0% of correct answers, chewing had only 17.3%, and 40.9% reported that none of the actions presented a risk of bacteremia. When comparing variables, the correct prescription of amoxicillin (2 g, 30-60 minutes before the procedure) was more prevalent among cardiologists and in responders with less than 20 years of graduation (p<0.01). Conclusion In the present study, the prescription of antibiotic prophylaxis for IE were frequent for high- and moderate-risk patients, before oral/dental procedures. Partial knowledge was found about endocarditis, which highlights the need for continuous medical/dental education.

Desordens orais potencialmente malignas: o que o cirurgião-dentista precisa saber? / Oral potentially malignant disorders: what do dentists need to know?

Introdução:as desordens orais potencialmente malignas (DOPMs) são condições que podem preceder o aparecimento do câncer em cavidade bucal. Objetivo: descrever os principais aspectos clínicos, histológicos e tratamento da leucoplasia, eritroplasia, queilite actínica e líquen plano oral. Metodologia: trata-se de uma revisão da literatura atual, em que foram consultados artigos nas bases do MEDLINE/PUBMED e Biblioteca Virtual em Saúde, publicados nos últimos 10 anos. Os descritores foram localizados usando o vocabulário controlado do MeSH, sendo eles: Leukoplakia; Erythroplakia, Actinic cheilitis, Oral lichen planus, Diagnosis, Therapeutics. Resultados: asapresentações clínicas das DOPMs são diversas. A leucoplasia é a mais comum e deve ser distinguida da leucoplasia verrucosa proliferativa que tem uma apresentação clínica generalizada e uma tendência à recorrência após a excisão; a eritroplasia, embora rara, tem maior chance de malignização. A queilite actínica acomete com frequência o lábio inferior, tem forte relação com exposição solar e pode progredir para o carcinoma escamocelular labial; o líquen plano oral tem uma variedade de apresentações clínicas, sendo a forma reticular a mais comum. O tipo erosivo, atrófico ou bolhoso é acompanhado de sintomatologia dolorosa variável. A biópsia é essencial para confirmar a suspeita clínica das DOPMs e o encaminhamento oportuno para um especialista é indicado. Conclusão: as DOPMs podem ser encontradas durante o exame bucal, possibilitando assim, o diagnóstico precoce, e o correto encaminhamento a um especialista e a intervenção adequada, podendo reduzir a taxa de progressão dessas condições para câncer.

Introduction: Oral Potentially Malignant Disorders (OPMDs) are conditions that may precede the onset of cancer in the oral cavity. Objective: To describe the main clinical features, histological aspects and treatment of leukoplakia, erythroplakia, actinic cheilitis and oral lichen planus. Methodology: this is a review of the current literature, in which articles in the databases of MEDLINE/PUBMED and the Virtual Health Library, published in the last 10 years, were consulted. The descriptors were located using the MeSH controlled vocabulary, namely: Leukoplakia; Erythroplakia, Actinic cheilitis, Oral lichen planus, Diagnosis, Therapeutics. Results:the clinical presentations of OPMDs are diverse. Leukoplakia is the most common and must be distinguished from proliferative verrucous leukoplakia which has a generalized clinical presentation and a tendency to reoccur after excision; erythroplakia, although rare, has a greater chance of becoming malignant. Actinic cheilitis frequently affects the lower lip, is strongly related to sun exposure and can progress to labial squamous cell carcinoma; oral lichen planus has a variety of clinical presentations, with the reticular form being the most common. The erosive, atrophic or bullous type is accompanied by different levels of pain. Biopsy is essential to confirm the clinical suspicion of OPMDs and timely referral to a specialist is indicated. Conclusion: OPMDs can be found during oral examination, thus enabling early diagnosis, correct referral to a specialist and appropriate intervention, which may reduce the rate of progression of these conditions to cancer.

Impact of Anxiety on Health-Related Quality of Life and Symptoms of Burnout in Multi-Professional Residents in Brazil During the COVID-19 Pandemic.

We aimed to determine the prevalence of anxiety and to identify associated factors among multi-professional residents in Brazil during the early days of the COVID-19 pandemic. A cross-sectional study included a sample of 752 multi-professional residents selected by snowball technique. Symptoms of anxiety were measured by the Beck anxiety inventory scale (≥ 16 cut-off). We used WHOQOL-BREF to access the health-related quality of life and the Maslach Burnout Inventory to measure the burnout syndrome. PR and respective 95% confidence intervals (CI) were calculated using the Poisson regression model. The prevalence of anxiety was 41.2% (310/752). Some variables were strongly associated with anxiety: afraid of getting COVID-19; extra work demand during COVID-19 pandemic; sweating/wheezing/increased heart rate during work; feeling safe when using personal protective equipment at work, and psychological support from residence preceptors. Residents with symptoms of anxiety showed high emotional exhaustion at work (36.6 ± 9.6 vs. 24.7 ± 10.7, P = 0.001) and depersonalization (8.9 ± 6.0 vs. 5.6 ± 4.9, P = 0.001). Correlations coefficients between emotional exhaustion versus Physical WHOQOL-BREF and between emotional exhaustion versus Psychological WHOQOL-BREF were significantly lower among residents without anxiety (P = 0.027 and P = 0,03, respectively). The prevalence of anxiety was high and strongly associated with several variables, particularly with being afraid of getting COVID-19, the perception of workload, somatization (sweating, wheezing and increased heart rate during work), feeling unsafe when using personal protective equipment, and lack of psychological support from residence preceptors. Anxiety was associated with increased emotional exhaustion and depersonalization and low health-related quality of life during the COVID-19 pandemic in Brazil. Low WHOQOL-BREF environment domain, and high emotional exhaustion MBI domain increased the chances of presenting symptoms of anxiety.

Work ability and associated factors in people living with human T-cell leukemia virus type 1.

BACKGROUND: Infection with the human T-lymphotropic virus type 1 (HTLV-1) affects an estimated 10-15 million people worldwide. However, knowledge of the impact of HTLV-1 infection on work ability is lacking. This study aimed to measure the frequency and identify factors associated with poor work ability in patients living with HTLV-1. METHODS: This cross-sectional study included 207 individuals infected with HTLV-1 who attended the University Hospital in Salvador, Bahia, Brazil. HTLV-1 antibodies were detected in the participants' blood by enzyme-linked immunosorbent assay (ELISA) and confirmed by western blotting. Participants answered a questionnaire on sociodemographic data, personal habits, clinical data, health-related quality of life, and work ability, evaluated using the work ability index questionnaire. A Poisson regression model with a robust variance estimate was used to identify the factors associated with the prevalence of poor work ability. RESULTS: Patients mean age was 55.2, ranging from 19 to 84 years, 73.0% were females, 100% had monthly family income less than US$ 394, and 33.8% presented HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). No individual was classified as having excellent work ability. Poor work ability prevalence was strongly associated (prevalence ratio; 95% confidence interval [CI]) with sedentarism (1.30; 1.03-1.65), neurological symptoms (1.25; 1.02-1.52), and low physical (0.95; 0.94-0.96) and mental (0.98; 0.97-0.99) component summaries of health-related quality of life. CONCLUSIONS: Poor work ability among people living with HTLV-1 is associated with sedentarism, neurologic symptoms, and low health-related quality of life.

Obesity in young women is positively associated with periodontitis.

OBJECTIVE: This cross-sectional study was performed to investigate the association between excess body weight and periodontitis in adults, stratified by sex and age, and using different criteria for obesity. MATERIAL AND METHODS: Enrolled in the study were 345 individuals with a minimum age of 18 years who had attended the Public Health Service in the city of Salvador, Bahia, Brazil. All individuals underwent a complete periodontal examination and anthropometric measurements and answered a questionnaire regarding their socioeconomic, demographic, health, and lifestyle conditions. Excess body weight (exposure factor) was defined using body mass index (BMI) and waist circumference (WC). Prevalence ratios (PRs) and 95% confidence intervals (95%CI) were obtained by Poisson regression analysis with robust variance. RESULTS: Periodontitis was found in 74.2% of study participants, with the disease being more prevalent among those individuals with increased WC. The occurrence of overweight was 44.4% and that of obesity ranged from 29.9 to 70.8%, dependent upon the specific definition of obesity that was used. There was a positive association between obesity (WC > 88 cm) and periodontitis only among women, after adjustment for age, smoking habit, education level, diabetes, and family income (PRadjusted: 1.20; 95%CI: [1.01-1.44]). The magnitude of this positive association was higher among women aged 18 to 49 years when the outcome was severe periodontitis, and the exposure was obesity defined by WC. CONCLUSIONS: The findings draw attention to the high frequency of the diseases investigated: overweight, obesity and periodontitis. Moreover, obesity was positively associated with periodontitis in women and younger individuals, demonstrating that among those with obesity, there is a higher probability of having periodontitis. The smaller number study of men in the may have influenced the non-statistically significant association found in that group. CLINICAL RELEVANCE: Obese females and younger people are more likely to also have periodontitis. Periodontal evaluation and clinical management of individuals with obesity is recommended.

Hiperplasia epitelial focal: relato de caso clínico / Focal epithelial hyperplasia: case report

Introdução: a hiperplasia epitelial focal (HEF) ou doença de Heck, caracteriza-se por ser uma lesão benigna rara da mucosa bucal. Geralmente, está associada a proliferação do epitélio pavimentoso atribuída principalmente ao papiloma vírus humano (HPV) dos subtipos 13 e 32. Objetivo: relatar o caso de um paciente, com suspeita diagnóstica de HEF, descrever suas manifestações clínicas bucais e histopatológicas. Metodologia: homem, 38 anos, melanoderma, compareceu no Serviço Universitário com queixa de ardência em mucosa bucal. Ao exame clínico, apresentava múltiplas lesões papulares, firmes à palpação, de coloração rósea, com pápulas aglomeradas ou isoladas, localizadas em rebordo alveolares, gengiva inserida e livre da arcada superior e inferior, mucosas jugais e labiais, compatíveis com lesões causadas por HPV. Realizou-se biópsia incisional das lesões bucais, o laudo histopatológico descreveu o fragmento de mucosa bucal que estava revestida por epitélio pavimentoso estratificado paraceratinizado com acantose proeminente, projeções focais confluentes para o tecido conjuntivo, confirmando a suspeita diagnóstica clínica. Conclusão: a HEF é uma patologia rara, benigna da mucosa, indolor e que pode se resolver espontaneamente. Portanto, é necessário o diagnóstico adequado através da biopsia e laudo histopatológico.

Introduction: focal epithelial hyperplasia (FEH) or Heck's disease is characterized as a rare benign lesion of the oral mucosa. It is usually associated with proliferation of the squamous epithelium, mainly attributed to human papillomavirus (HPV) subtypes 13 and 32. Objective: to report the case of a patient with a diagnostic suspicion of HEF, to describe its oral clinical and histopathological manifestations. Methodology: hale, 38 years old, black, attended the University Service with a complaint of burning in the oral mucosa. On clinical examination, she presented multiple papular lesions, firm to palpation, pink in color, with agglomerated or isolated papules, located in the alveolar ridge, inserted gingiva free from the upper and lower arch, jugal and labial mucosa, compatible with lesions caused by HPV. An incisional biopsy of the oral lesions was performed, the histopathological report described the fragment of oral mucosa that was lined with parakeratinized stratified squamous epithelium with prominent acanthosis, focal projections confluent to the connective tissue, confirming the clinical diagnostic suspicion. Conclusion: FEH is a rare, benign mucosal pathology, painless and can resolve spontaneously. Therefore, proper diagnosis through biopsy and histopathological report is necessary.

Gene expression profile of chronic oral graft-versus-host disease.

Among the complications observed after allogeneic hematopoietic stem cell transplantation, graft-versus-host disease (GVHD) is the primary cause of post-transplant mortality. The oral cavity is the second most affected organ target in chronic GVHD. Tissue damage results from the upregulation of inflammatory mediators, which play a critical role in the immunopathogenesis of the disease. This case series observational study aims to evaluate the participation of cytokines, chemokines, transcription factors, and heat shock proteins in the pathogenesis of oral GVHD (oGVHD), describing the mRNA expression of 28 genes selected. Peripheral blood mononuclear cells were isolated from six participants with oGVHD and two without GVHD, and relative expression of transcripts with established roles as inflammatory mediators was determined in triplicate using the human RT2 Profiler™ PCR Array. The gene expression levels in the group with oGVHD were mainly up-regulated compared to those without GVHD. PBMC from oGVDH expressed consistently higher IFN-γ, TNF, IL-1ß, CCL2, HSP60 (HSPD1) and HSP90 (HSP90B1). These results can provide a basis for developing new molecular diagnostics and targets therapies for the clinical management of oGVHD.

Oral health and quality of life of people living with human T-cell leukemia virus-1 in Salvador, Brazil: a cross-sectional study.

OBJECTIVE: To compare the oral health status and oral health-related quality of life (OHRQoL) in symptomatic and asymptomatic patients with human T-cell leukemia virus-1 (HTLV-1). MATERIAL AND METHODS: This cross-sectional study included 204 seropositive patients, classified into two groups, symptomatic and asymptomatic. The first group included patients with neurological symptoms associated with HTLV-1 (n = 69), and the second group, asymptomatic HTLV-1 carriers (n = 135). We evaluated the total unstimulated saliva flow, oral mucosa, the Decayed, Missing, Filled Teeth (DMFT) index, and Periodontal Screening and Recording (PSR). The Oral Health Impact Profile (OHIP14) measured the oral health-related quality of life. General health-related quality of life was measured by the 36-Item Short-Form Health Survey (SF-36). Variables with a value of p < 0.25 in bivariate analysis were selected, together with SF-36 summaries' scores and total OHIP-14, for composing a logistic regression model that had symptomatology as the dependent variable. RESULTS: The OHIP-14 total score was poor in symptomatic and asymptomatic groups, but with no marked difference between them. Symptomatic patients showed significantly lower SF-36 scores (P ≤ 0.05) compared to asymptomatic ones, except for mental component summary (MCS). Family income (1-2.99 minimal wages), reduced salivary flow, flossing, and lower physical component summary (PCS) were associated (P ≤ 0.05) with symptomatology. CONCLUSIONS: Symptomatic individuals living with HTLV-1 showed lower HRQoL and poorer OHRQoL compared to asymptomatic ones. Family income, flossing, reduced salivary flow, and lower PCS were associated with symptomatic HTLV-1 individuals. CLINICAL RELEVANCE: In the present study, symptomatic individuals with HTLV-1 showed higher family income, poorer oral health status, lower salivary flow, poorer OHRQoL, and lower HRQoL compared to asymptomatic ones.

Work ability and associated factors in people living with human T-cell leukemia virus type 1

ABSTRACT Background: Infection with the human T-lymphotropic virus type 1 (HTLV-1) affects an estimated 10-15 million people worldwide. However, knowledge of the impact of HTLV-1 infection on work ability is lacking. This study aimed to measure the frequency and identify factors associated with poor work ability in patients living with HTLV-1. Methods: This cross-sectional study included 207 individuals infected with HTLV-1 who attended the University Hospital in Salvador, Bahia, Brazil. HTLV-1 antibodies were detected in the participants' blood by enzyme-linked immunosorbent assay (ELISA) and confirmed by western blotting. Participants answered a questionnaire on sociodemographic data, personal habits, clinical data, health-related quality of life, and work ability, evaluated using the work ability index questionnaire. A Poisson regression model with a robust variance estimate was used to identify the factors associated with the prevalence of poor work ability. Results: Patients mean age was 55.2, ranging from 19 to 84 years, 73.0% were females, 100% had monthly family income less than US$ 394, and 33.8% presented HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). No individual was classified as having excellent work ability. Poor work ability prevalence was strongly associated (prevalence ratio; 95% confidence interval [CI]) with sedentarism (1.30; 1.03-1.65), neurological symptoms (1.25; 1.02-1.52), and low physical (0.95; 0.94-0.96) and mental (0.98; 0.97-0.99) component summaries of health-related quality of life. Conclusions: Poor work ability among people living with HTLV-1 is associated with sedentarism, neurologic symptoms, and low health-related quality of life.

Clinical and Laboratory Profile of People Living with HIV/AIDS with Oral Kaposi Sarcoma.

The aim of this article was to evaluate the clinical and laboratory profile of people with oral Kaposi's sarcoma (KS) associated with AIDS (KS-AIDS), followed-up at a public university hospital in Salvador, Bahia, Brazil, in the past 10 years. We identified patients diagnosed with KS-AIDS, presenting oral manifestation from January 2007 to December 2017. We searched, in the hospital information systems, the patient demographics, diagnostic data, treatment, image studies, and oral photographic records. Of the 39 cases of KS-AIDS identified at the institution, 14 (22.8%) presented oral lesions. There was a predominance of black men, with a mean age of 32.5 years. Most cases (85.1%) manifested signs of KS simultaneously with the diagnosis of HIV infection, with extremely low initial CD4 T cell counts (average of 52.6 cells/mm2) and visceral involvement (64.3%). The palate (32.1%) and gingiva (21.4%) were the most affected oral sites. Histologically, the tumors exhibited proliferation of spindle cells between vascular clefts and extravasated erythrocytes. Oral KS-AIDS was frequent in young black adult men, with severe immunosuppression and high viral load counting, mostly with lesions manifested in the same period of diagnosis of infection by the HIV.

A Comparative Study of Multidetector Computed Tomography, Cone Beam Computed Tomography, and Computed Microtomography on Trabecular Bone Structures in the Human Mandible: An Ex Vivo Study.

OBJECTIVE: The aim of this study was to evaluate the accuracy of multislice computed tomography (MSCT) and cone beam computed tomography (CBCT) scanners in the assessment of trabecular bone microarchitecture by radiomorphometric analysis. METHODS: Eight dry human hemimandibles were selected and scanned by 4- and 128-MSCT, CBCT with different voxel sizes, and a computed microtomography (micro-CT). The images were spatially aligned, the axial slices were segmented using CTAn software (Skyscan, Konitch, Belgium), and 10 bone morphometric parameters were quantified. The micro-CT images were the criterion standard. RESULTS: The results show the superiority of CBCT images with 0.2-mm voxel size and 128-MSCT. CONCLUSIONS: We can conclude that the CBCT scanner with 0.2-mm voxel size and 128-MSCT had better performance on reproducibility of the distribution and organization of trabecular bone and marrow spaces evaluated in this study.

Linear measurement accuracy of CBCT panoramic reconstructions: experimental study with dry human mandibles.

INTRODUCTION: Studies on software accuracy of reformatted panoramic computed tomography (CT) images are scarce. OBJECTIVES: The aim of this study was to evaluate the software accuracy of reformatted panoramic views from cone-beam computed tomography (CBCT). METHODS: Ten dry mandibles were scanned using CBCT with different voxel sizes. Following the reconstruction of panoramic views with three different software, horizontal and vertical linear measurements were performed using the electronic rules of each software. Measurements of the corresponding dry mandibles were taken with a digital caliper and defined as the gold standard. RESULTS: There were no statistically significant differences in linear distances among the dry mandibles and reformatted panoramic CT views. The relative error ranged from 1.3 to 8.0%, depending on the software and voxel size. CONCLUSIONS: The linear measurements on reformatted panoramic views are reliable.

Oral health-related quality of life in individuals with severe asthma / Qualidade de vida relacionada à saúde bucal em indivíduos com asma grave

ABSTRACT Objective: To evaluate oral health-related quality of life (OHRQoL) among individuals with severe asthma, comparing it with that observed among individuals with mild-to-moderate asthma and individuals without asthma. Methods: We conducted a cross-sectional study of 125 individuals: 40 with severe asthma; 35 with mild-to-moderate asthma; and 50 without asthma. We calculated the decayed, missing, and filled teeth (DMFT) index, as well as the Periodontal Screening and Recording index, and determined the stimulated salivary flow rate. We applied three structured questionnaires: the 14-item Oral Health Impact Profile (OHIP-14); the Medical Outcomes Study 36-Item Short-Form Health Survey, version 2 (SF-36v2); and the Work Ability Index (WAI). Results: Periodontitis and reduced salivary flow were both more common in the severe asthma group than in the mild-to-moderate asthma and no-asthma groups. In addition, the WAI scores were lower in the severe asthma group than in the mild-to-moderate asthma and no-asthma groups, as were the scores for all SF-36v2 domains. The individuals with severe asthma also scored lower for the OHIP-14 domains than did those without asthma. Although the mean DMFT index did not differ significantly among the groups, the mean number of missing teeth was highest in the severe asthma group. Strong correlations between the SF-36v2 Component Summaries and poorer OHRQoL were only observed in the severe asthma group. Conclusions: Severe asthma appears to be associated with poorer oral health, poorer OHRQoL, a lower WAI, and lower scores for SF-36v2 domains.

RESUMO Objetivo: Avaliar a qualidade de vida relacionada à saúde bucal (QVRSB) em indivíduos com asma grave, comparando-a com a observada em indivíduos com asma leve a moderada e sem asma. Métodos: Trata-se de um estudo transversal com 125 indivíduos: 40 com asma grave, 35 com asma leve a moderada e 50 sem asma. Foram avaliados o índice de dentes cariados, perdidos e obturados (CPO-D), o Periodontal Screening and Recording (PSR, Registro Periodontal Simplificado) e o fluxo salivar estimulado. Foram aplicados três questionários estruturados: o 14-item Oral Health Impact Profile (OHIP-14), o Medical Outcomes Study 36-Item Short-Form Health Survey, version 2 (SF-36v2) e o Índice de Capacidade para o Trabalho (ICT). Resultados: Periodontite e fluxo salivar reduzido foram mais comuns no grupo com asma grave do que nos grupos com asma leve a moderada e sem asma. Além disso, a pontuação obtida no ICT e em todos os domínios do SF-36v2 foi menor no grupo com asma grave do que nos grupos com asma leve a moderada e sem asma. A pontuação nos domínios do OHIP-14 também foi menor nos indivíduos com asma grave do que naqueles sem asma. Embora não tenha havido diferença significativa entre os grupos quanto à média do índice CPO-D, a maior média de dentes perdidos foi observada no grupo com asma grave. Correlações fortes entre os Resumos dos Componentes do SF-36v2 e pior QVRSB foram observadas apenas no grupo com asma grave. Conclusões: A asma grave parece estar relacionada com pior saúde bucal, pior QVRSB, menor ICT e menor pontuação nos domínios do SF-36v2.

Corticosteroid Use and Periodontal Disease: A Systematic Review.

Periodontitis affects the teeth supporting structures, such as periodontal tissues. We aimed to evaluate the association between periodontal disease and corticosteroid use. We searched in MEDLINE, Web of Sciences, SCOPUS, LILACS, and Cochrane databases, using the descriptors "Periodontal diseases" AND ("adrenal cortex hormones" OR "adrenal cortex hormones" OR ("adrenal" AND "cortex" AND "hormones") OR "adrenal cortex hormones" OR "corticosteroid"). We selected the summaries of observational studies, addressing periodontal disease in patients using corticosteroids. The search resulted in 403 articles. After applying the selection criteria, eight studies remained; being two retrospective cohorts and six cross-sectional studies. There are few studies with appropriate methodology to produce sound evidence about the causal relationship between the use of corticosteroids and periodontitis. However, two retrospective cohorts confirmed that chronic corticosteroid use is associated with the incidence of periodontal disease. Dental staff must be aware of this association for better management of periodontal disease therapy in patients using corticosteroids.

Frequência de fenestração do canal mandibular em imagens de tomografia computadorizada multidetectores / Frequency of mandibular canal fenestration in multislice computerized tomography images

Introdução: o conhecimento das variações anatômicas que podem acometer o canal mandibular (CM) é importante, pois, para a realização de procedimentos cirúrgicos mandibulares a presença dessas variantes pode comprometer o sucesso do procedimento. A fenestração do CM é uma variação anatômica caracterizada pela exposição do feixe neurovascular inferior (FNVI) por ausência da cortical óssea, sem estar associada a processos patológicos, consequentemente, ampliando os riscos de danos ao mesmo quando de procedimentos cirúrgicos na região. Objetivo: avaliar por meio de tomografia computadorizada (TC) multidetectores a frequência de fenestração nas corticais ósseas da mandíbula, no percurso do CM e relacioná-la à idade, sexo e lado afetado. Metodologia: a amostra foi constituída por 150 exames de TC da mandíbula, num total de 300 CM avaliados. Como critério de inclusão, o exame deveria permitir a observação de toda a extensão do CM. Foram excluídos os exames que apresentavam doenças ósseas ou artefatos metálicos que dificultassem a observação da área de interesse. Todos os exames foram analisados por um avaliador por duas vezes com o intervalo mínimo de uma semana entre as avaliações, e os resultados foram submetidos à análise estatística descritiva. Resultados: Dos 300 CM analisados 1% da amostra, o que equivale a três casos, apresentou fenestração do CM, sendo todas localizadas no lado esquerdo da mandíbula. Em dois casos, a fenestração estava associada a terceiros molares inclusos em posição horizontal. Conclusão: a fenestração do CM foi uma variação anatômica rara na amostra avaliada, porém esteve mais frequentemente associada a terceiros molares impactados em posição horizontal.

Introduction: knowledge of the anatomical changes that affect the mandibular canal (MC) is important, as it is for performing mandibular surgical procedures and the presence of these variables can compromise or be successful in the procedure. MC fenestration is a variation characterized by the exposure of the inferior alveolar neurovascular bundle (IANC) due to lack of bone cortical, without being associated with pathological processes, consequently, increasing the risks and damage and the same when surgical procedures in the region. Objective: to analyze by means of multidetector computed tomography (CT) the frequency of fenestration in the cortical of the mandible, in the course of the MC and to relate with age, sex and affected side. Methodology: the sample consisted of 150 CT examinations of the mandible, in a total of 300 MC evaluated. As an inclusion criterion, the exam should allow the observation of the entire length of the MC. Examinations that presented bone diseases or metallic artifacts that made it difficult to observe the area of interest were excluded. All examinations were reviewed by an evaluator twice with a minimum interval of 1 week between evaluations, and the results were analyzed by descriptive statistical analysis. Results: of the 300 MC analyzed, 1% of the sample, which is equivalent to three cases, presented fenestration of the MC, all of which were located on the left side of the mandible. In two cases, fenestration was associated with third molars included in a horizontal position. Conclusion: CM fenestration was a rare anatomical variation in the evaluated sample, but it was more frequently associated with impacted third molars in a horizontal position.

Orofacial manifestations of mucocutaneous leishmaniasis: a case series from Brazil.

The dental surgeon plays a fundamental role in the early diagnosis of oral leishmaniasis, since oral mucosa may be the primary site of the disease manifestation. This study reports seven clinical cases of orofacial mucocutaneous leishmaniasis. All had mucocutaneous leishmaniasis with oropharyngeal involvement confirmed by laboratory tests. Five out of the seven cases were males, and in four cases, patients had associated comorbidities. Late diagnosis was observed, resulting in treatment delay and increased hospitalization stay. One patient had severe psychological consequences due to facial deformity. The lack of differential diagnosis due the great variability of clinical presentation of the lesions and frequent unspecific histopathology represent a challenge for the dental surgeon. In two reported cases, there were unspecific biopsy results. The multidisciplinary approach plays an important role in orofacial leishmaniasis diagnosis and treatment. Leishmaniasis should be investigated in case of atypical and persistent lesions in patients from endemic regions. This recommendation may avoid diagnosis delays and decrease dissemination of the disease.

Peripheral T-cell non-Hodgkin lymphoma manifesting as a primary lesion on the lip: A rare case report.

Primary manifestations of extraganglion non-Hodgkin lymphoma (NHL) from T-cells in the oral cavity are rare and often difficult to diagnose. Herein, we describe a case of T-cell NHL with a primary lesion on the lip diagnosed with a 25-year-old woman. The patient reported the appearance of the initial lesion on the upper lip, which advanced to the hard palate and oral mucosa. Histological examination and immunohistochemistry were compatible with peripheral T-cell NHL without further specifications. The proposed treatment consisted of six cycles of multiagent chemotherapy. The patient died from complications of the disease before the third cycle of chemotherapy. Understanding the clinical signs of lymphoma is important for the early diagnosis of this disease to avoid aggressive and potentially fatal behavior.

Oral health and health-related quality of life in HIV patients.

BACKGROUND: Oral health care may improve the health-related quality of life (HRQoL) of HIV/AIDS patients. We aimed to evaluate oral health and HRQoL of HIV/AIDS patients using antiretroviral therapy. METHODS: A cross-sectional study included 120 HIV-infected patients, aged ≥18 years, from February, 2016 to September, 2017. The 36-Item Short Form Health Survey (SF-36) was used to evaluate the HRQoL. We assessed dental caries status using the Decayed, Missing and Filled Teeth (DMFT) index. Information about demographic, socioeconomic status, depression, and other comorbidities were collected. All patients with depression had a medical diagnosis. Comorbidities were defined as medical diagnoses of arterial hypertension, type-2 diabetes, tuberculosis, syphilis, cardiopathy, chronic renal failure, lymphoma, HCV infection, HBV infection and fatty liver disease. Independent t-tests were used to compare differences between mean levels of HRQoL, age, and DMFT and its components according to groups of sex, comorbidities and depression. Simple linear regression was used to analyze the relationship between the Mental Component Summary (MCS) and DMFT, and a multiple regression equation investigated depression, age, MCS, and comorbidities as predictors of DMFT. RESULTS: The mean DMFT index was 12.4 ± 8.2. A linear regression equation estimated a significant (p = 0.022) decrease of 0.25 unit (%) in MCS for each unit increase in DMFT. Among depressed patients, a significant (p = 0.008) decrease of 0.67% in MCS for each unity increase in DMFT was estimated. Depressed patients showed worse oral health indicators (DFMT index; p ≤ 0.001; and mean Missing Teeth; p ≤ 0.052) and lower HRQoL domains than non-depressed patients. DMFT remained associated with depression (P < 0.005) after controlling for age, MCS, and comorbidities. CONCLUSIONS: We found association between poorer oral health (higher DMFT index) and lower Mental Health Component Summary in HIV-infected patients with depression. Patients with depression deserve especial attention to their HRQoL and oral care.
