Clinical oral profile of pediatric patients with atopic dermatitis: A cross-sectional study.

OBJECTIVES: This work aims to describe oral health conditions, eating habits, and oral hygiene in pediatric and adolescent patients with atopic dermatitis and correlate them with the severity of the Scoring Atopic Dermatitis (SCORAD). Also, we aim to estimate the effect of several variables on the diagnosis of dental caries in these patients. MATERIAL AND METHODS: A total of 92 children and adolescents with atopic dermatitis had their oral cavities examined. The effect of independent variables on the diagnosis of dental caries (outcome) was assessed using multiple binary logistic regression model. RESULTS: Mild patients presented higher score of decayed, missing, and filled teeth in permanent dentition than moderate patients (p = 0.040). In the multivariable regression final model, the covariates using inhaled corticoid (OR = 6.4; p = 0.003), type of teething [deciduous dentition (OR = 7.9; p = 0.027) and mixed dentition (OR = 10.5; p = 0.007)], and brushing quality [poor mechanical control (OR = 10.6; p < 0.0001)] demonstrated significant direct effect on the diagnosis of dental caries. CONCLUSIONS: Our findings suggest that the presence of dental biofilm, use of inhaled corticoid, and type of teething are related to the presence of caries in atopic dermatitis patients.

Study of the causes of facial fractures in a reference center in Rio de Janeiro, Brazil from 2003-2012.

OBJECTIVE: This study describes the facial fractures of patients at a reference center in oral and maxillofacial surgery of a Public University Hospital in the city of Rio de Janeiro, from January 2003 to December 2012. METHODS: The data were collected from medical records and included the fractured bones, etiology, gender, and age of the patients. A total of 202 cases were identified, and 159 were included in the study (129 men and 30 women). RESULTS: The mandible was the most commonly injured bone (90 cases, 73 men and 17 women) with a mean age of 33.7 years old (±15.2), and traffic accidents (75 cases) were shown to be the major cause. CONCLUSION: In the city of Rio de Janeiro, young men in their fourth decade of life are prone to trauma to their facial bones, especially the mandible, and they are most commonly caused by traffic accidents.

Short Implant and Heavy Smokers as Predictors for Failure of Immediate Implants: a Retrospective Study.

Background: The possibility of installing implants in fresh sockets was first proposed as a viable treatment option in the 1970s. Objective: to assess the relationships of subject-level and implant-level characteristics on the failure of immediate implants installed in sites that contained teeth associated or not with chronic apical periodontitis. Material and Methods: A retrospective study was undertaken with data from patients who received immediate implants with a minimum follow-up of 12 months after loading. The Generalized Estimating Equation, applying a multiple logistic regression model, was employed to investigate the association between predictor variables/co-variables and failure of the immediate implants. Results: Four hundred and twenty-three implants were installed (208 uninfected/215 infected sites) in 186 patients (92 men/96 women) with a mean age of 57.1 years old. The survival rate of implants was 91%. Approximately half (215/50.8%) of the alveoli that received immediate implants had chronic apical periodontitis associated with the extracted teeth, and 191 (88.8%) of these survived until the last follow-up visit. When the infection-free sites were analyzed, this frequency was higher (93,3%), but the presence of chronic apical periodontitis did not show statistical significance in the implant failure (p=0.167). Smokers with a consumption of more than 20 cigarettes/day and short implants had more failures (OR:7.66, p=0.012; OR:14.06, p=0.002; respectively). Conclusions: Short implants and consumption of more than 20 cigarettes/day were important predictors for failure of immediate implants, regardless of presence of chronic apical periodontitis. Key words:Osseointegration, dental implant, smokers, study, immediate dental implant loading.

Deciduous Molars Complexity Anatomy Reveled by Computed Microtomography.

OBJECTIVE: The aim of this study was to analyze the internal morphology of deciduous molars through the use of computed microtomography in a sample from Rio de Janeiro. MATERIAL AND METHODS: Thirty maxillary and 30 mandibular deciduous molars (n = 60), divided in first and second primary molars, were scanned by computed microtomography. The teeth were evaluated for root number, root canals, Vertucci classification, root curvature, presence of lateral canals, furcation dentin thickness, structure model index (SMI), volume, and canal surface area. RESULTS: The results showed 100% of maxillary molars had three roots and Vertucci type I canal was more prevalent in this group. In the mandibular ones, type IV was more frequent in the mesial root and class I in the distal root and the cavo-interradicular canal occurred in 2 specimens. Dentin thickness in the furcation region measured 1.53 and 1.59 mm in the maxillary and mandibular, respectively. Volume and area parameters varied according to the evaluated canals and SMI demonstrated that all canals had a cylindrical shape. CONCLUSION: More detailed information about the internal anatomy of the primary molars has been described, which may help strategies in the preparation of these root canals.

Comparison of antibacterial activity of alexidine alone or as a final irrigant with sodium hypochlorite and chlorhexidine.

AIMS: To compare the antibacterial activity of alexidine (ALX) alone or as a final irrigant in combination with sodium hypochlorite (NaOCl), with the most common canal irrigants, NaOCl and chlorhexidine (CHX). MATERIALS AND METHODS: Ninety-four root fragments from extracted human teeth were infected with Enterococcus faecalis for 24 h and then distributed into 4 groups of 20 fragments each. The NaOCl, CHX and ALX groups were immersed in 1 ml of 2.5% NaOCl, 2% CHX, and 1% ALX for 10 min, respectively. The samples of the NaOCl+ALX group were immersed in 1 ml of 2.5% NaOCl for 10 min followed by 1% ALX for 10 min. Bacteriological samples were taken, cultured, and the colony-forming units were counted. RESULTS: There was no significant differences among the experimental groups (P>0.05) except for the comparisons CHX versus ALX and NaOCl+ALX versus ALX (P=0.004). ALX alone was the worst irrigant. CHX and NaOCl+ALX eradicated all bacteria. All experimental groups were significantly more effective than the control group immersed in saline (P<0.05). CONCLUSIONS: The antibacterial effect of ALX alone was inferior to 2% CHX and 2.5% NaOCl. However, the combination of NaOCl with ALX as a final irrigant eradicated the biofilms.

Is YouTubeTM a reliable source of information regarding ultra-thin ceramic laminates?

An aesthetic smile is usually associated with healthy appearance and success in many areas of life. Currently, individuals access the internet and social media in search of health information. The aim of this study was to analyse the quality and reliability of information in videos available on the YouTubeTM platform about ultra-thin ceramic laminates. Methods: YouTubeTM was searched using the therms "dental ceramic laminates" and "dental contact lens" for videos uploaded on ultra-thin ceramic laminates. The first 100 videos in Portuguese were selected and rated for quality and reliability. The content and source of videos were also noted. The quality of the videos was determined by evaluating the presence or absence of reliable information and distributed into seven domains. To compare the distributions of quantitative variables between the classifications of source, content, and quality, the Kruskal-Wallis and Dunn's post-hoc tests were performed. Results: Seventy-two videos were included for qualitative analysis. Regarding quality rating, most videos were rated with poor quality. The reliability of the evaluated videos was low. Conclusion: YouTubeTM showed a large number of videos with many views on the topic, but it does not contribute with good quality and reliable information to the population

Sulfate-Reducing Bacteria: Biofilm Formation and Corrosive Activity in Endodontic Files.

AIM: This study describes the biofilm formation and the corrosive capacity of sulfate-reducing bacteria (SRB) on the metallic structure of used endodontic files. METHODS: Sulfate-reducing bacteria (SRB) (Desulfovibrio desulfuricans oral and Desulfovibrio fairfieldensis or D. desulfuricans environmental) were inoculated into the culture media (Postgate C culture medium or modified Postgate E culture medium). The biocorrosive potential of these bacteria will be an important component of a biopharmaceutical under development called BACCOR. Afterwards, four used endodontic files (UEFs) were separately inoculated into a specific culture media for 445 days at 30°C in an incubator. The four UEFs were placed in a scanning electron microscope (SEM) and analyzed by the energy-dispersive X-ray spectrometry (EDS). RESULTS: The confocal laser scanning microscopic images indicate the presence of biofilm in the four samples. The SEM and SEM-EDS revealed the presence of rough, irregular structures adhering along the metallic surface of the used endodontic files, suggesting a mature calcified biofilm with a high concentration of Ca, P, C, and S. CONCLUSION: The formation of SRB biofilms on used endodontic files shows characteristics that may contribute to the biocorrosion of these files, and the results may also provide complementary data for a biopharmaceutical, which is still under development to assist in the removal of fractured endodontic files inside root channels.

Oral Aspects Identified in Atopic Dermatitis Patients: A Literature Review.

INTRODUCTION: Atopic dermatitis is a chronic inflammatory skin condition that is more prevalent in children (10-20% of the world's population) than in adults. As its etiology is multifactorial, it is important to know the most frequent oral manifestations in atopic dermatitis patients. METHODOLOGY: In the last decades, the correlation between atopic dermatitis and conditions and/or changes in the oral cavity has been demonstrated by several studies. The objective of this paper was to describe, through a review of the literature, the oral health conditions and/or oral aspects identified in patients with atopic dermatitis. SEARCH STRATEGY: A descriptive literature review was carried out through a bibliographical survey based on the last 10 years, in order to answer the study questions. RESULTS: As a result, we found six studies with different sample sizes, ranging from 43 to 468 patients, and the majority of them were of cross-sectional study design. DISCUSSION: Two studies performed their analysis through dental exams and reported that patients with atopic dermatitis tend to have a greater frequency of carious lesions, and two studies correlated Candida with atopic dermatitis through mycological analyzes. CONCLUSION: There are a few studies in the literature that identify the oral aspects of atopic dermatitis. More investigations are needed in order to contribute to the knowledge of such oral aspects and the approach to treat these patients regarding oral health.

Aging effects in the expression of macrophages in post-treatment apical periodontitis lesions.

OBJECTIVES: To evaluate the CD68 immunoexpression in post-treatment apical periodontitis lesions of older patients and compare them with lesions of younger/middle age adults. METHODS: Biopsy specimens from 21 apical periodontitis lesions (12 granulomas and 9 cysts) were selected from older patients and 25 apical periodontitis lesions from younger/middle age adults (12 cysts and 13 granulomas) were selected and analyzed by immunohistochemistry using silanized slides with anti-CD68 antibody. The slides were subdivided in five high-power fields and the images were observed under an optical microscope to evaluate the epithelial and connective tissues. RESULTS: The results showed that there was no statistical difference for the CD68 expression in epithelial tissue of cysts between younger/middle age adults and older patients. However, for the connective tissue of both cysts and granulomas, there was a statistical difference between the two age groups. There was a statistical difference between the epithelial and the connective tissues in cysts of younger/middle age adults, and also when the epithelial tissue of the cysts was compared with connective tissue of the granuloma. In the group of older patients, there was no statistical difference between the connective tissue of the cysts and granulomas. CONCLUSION: The intensity of the macrophage staining was greater in the connective tissue of cysts and granulomas alike in the younger/middle age adult patients, suggesting that these cells participate actively in this tissue. Immune responses in older patients may be compromised, suggesting that there is a greater tendency for the endodontic treatment of these patients to fail.

Risk factors for survival after head and neck cancer: a cohort study in the south of Espirito Santo state

Introduction: Head and check squamous cell carcinomas (HNSCC) affects the Brazilian population with a high incidence and usually has a poor prognosis. Objective: To evaluate the risk factors for survival of patients diagnosed with HNSCC and investigate the influence of epidemiological and clinical factors on the prognostic of HNSCC in southeastern Brazil. Materials and Methods: Clinical records of 211 patients with head and neck squamous cell carcinomas diagnosed and treated between 2010 and 2018 at a reference hospital for oncology, were selected. Clinical and pathological characteristics at diagnosis and for 5 years follow up were collected. The Kaplan-Meier Curve with the Log-Rank test assessed survival, and forward stepwise multivariate logistic regression model was performed to determine the factors affecting HNSCC survival. Results: The 5-year overall survival was 30.0%. Laryngeal cancer was the most prevalent (34.1%), followed by oropharynx (33.6%) and oral cavity (24.2%). About 64% of patients had locally advanced tumors (T3 and T4) and 75.4% of the patients were diagnosed as being in the advanced clinical stages (III and IV). In the multivariate analysis, the locally advanced tumors (OR=2.748; 95%CI:1.310- 5.765), palliative chemotherapy (OR=15.757; 95%CI:5.868-42.309) and metastasis during oncological follow-up (OR=11.602; 95%CI:1.380-97.507) were associated with a poor prognosis. Conclusion: The survival rate was considered low when compared with the literature. Locally advanced tumors, palliative chemotherapy, and the appearance of metastases during follow-up were considered the most important risk factors associated with a low HNSCC survival.

Introdução: O carcinoma de células escamosas (CCE) de cabeça e pescoço possui alta incidência na população brasileira e normalmente está associado a um prognóstico desfavorável. Objetivo: Avaliar os fatores de risco para sobrevida de pacientes diagnosticados com CCE de cabeça e pescoço e investigar a influência de fatores clínicoepidemiológicos no prognóstico do CCE. Materiais e Métodos: Foram selecionados prontuários de 211 pacientes com CCE de cabeça e pescoço diagnosticados e tratados entre 2010 e 2018 em um hospital de referência em oncologia. Foram coletadas as características clínico-patológicas no momento do diagnóstico e nos 5 anos de acompanhamento. A curva de Kaplan-Meier com o teste Log-Rank avaliou a sobrevivência e o modelo de regressão logística multivariada progressiva foram realizados para determinar os fatores que afetaram a sobrevivência do CCE. Resultados: A sobrevida global em 5 anos foi de 30,0%. O câncer de laringe foi o mais prevalente (34,1%), seguido de orofaringe (33,6%) e cavidade oral (24,2%). 64% dos pacientes apresentavam tumores localmente avançados (T3 e T4) e 75,4% dos pacientes foram diagnosticados em estádios clínicos avançados (III e IV). Na análise multivariada, os tumores localmente avançados (RC = 2,748; IC 95%: 1,310-5,765), quimioterapia paliativa (RC = 15,757; IC 95%: 5,868-42,309) e metástases durante o acompanhamento oncológico (RC = 11,602; IC 95%: 1,380-97,507) foram associados a um pior prognóstico. Conclusão: A taxa de sobrevida foi considerada baixa. Tumores localmente avançados, quimioterapia paliativa e aparecimento de metástases durante o seguimento foram considerados os fatores de risco mais importantes associados a uma baixa sobrevida.

Covid-19 e Odontologia: análise de informações disponíveis em uma plataforma virtual. Um estudo descritivo e observacional / Covid-19 and Dentistry: analysis of available information on a virtual platform. A descriptive and observational study

Objetivo: avaliar as informações disponíveis no site de buscas Google® sobre a relação entre a odontologia e a infecção pelo novo Coronavírus, e sua concordância com a literatura atual. Material e Métodos: estudo descritivo e observacional, realizado em uma universidade privada em Rio de Janeiro, Brasil, através da utilização da plataforma de buscas Google® aonde analisou-se os sites através de um roteiro de perguntas previamente elaborado. Resultados: foram analisados 67 sites após buscas pelas expressões "Coronavírus e odontologia", "Saúde bucal e Coronavírus" e "Fratura de dente e Coronavírus". Apenas 24,2% das perguntas foram respondidas com conteúdo completo enquanto 62,5% não apresentavam os conteúdos e 13,3% simplesmente os citavam sem dar maiores esclarecimentos. Apesar disso, 99% dos conteúdos foram publicados por fontes confiáveis (órgãos renomados, sites privados de profissionais da saúde bucal ou matérias de jornal assessoradas por estes). Conclusão: Apesar de confiáveis, os resultados das buscas apresentaram pequena quantidade de informações que realmente auxiliariam o leigo no entendimento da relação entre Coronavírus e odontologia, o que demonstra a necessidade de criação de canais oficiais para disseminação destas para o público geral

Objective:to evaluate the information available on the Google® search site concerning the relationship between dentistry and infection with the new coronavirus, and its concurrence with the current literature. Material and Methods: a descriptive and observational study was conducted by a private university in Rio de Janeiro, Brazil, to analyze the Google® search platform and the sites found through a previously prepared questionnaire. Results: the expressions "Coronavirus and dentistry", "Oral health and Coronavirus" and "Tooth fracture and Coronavirus" searched produced 67 sites for analysis. However, only 24.2% of the questions of the questionnaire were answered fully, while 62.5% did not answer them at all and 13.3% simply cited them without giving details. Notwithstanding this, 99% of the contents were published by official entities, dental websites or articles assisted by oral health care professionals. Conclusion: although reliable, the search results presented little information that would really help a layperson understand the relationship between Coronavirus and dentistry, which demonstrates the need to create official channels to disseminate such information to the public in an appropriate manner

Trauma in Primary Teeth at a Specialized Service Center: Retrospective Cohort

Abstract Objective: To evaluate the factors associated with the occurrence of dental trauma in children up to six years of age and describe the results of clinical follow-up and possible sequelae. Material and Methods: A retrospective study was carried out with data collected from the dental records of 96 pediatric patients up to 6 years old with traumatized primary teeth who sought care from the. Pediatric Dental Trauma project of a private university in the city of Rio de Janeiro from July 2014 to July 2017, and who had clinical and radiographic follow-up for up to three months as of their initial visit. Results: 96 children (58.3% boys and 41.7% girls) included who presented 166 traumatized primary teeth. Intrusion was the most observed type of trauma and in 45.8% of cases, the care occurred one-week post trauma. The maxillary central incisors were the most affected teeth (97.6%). The prognosis of the dental elements with more than 3 months of follow-up was considered favorable, and 59.6% of the teeth did not present any clinical or radiological sequelae. Oral hygiene instruction and monitoring were the most common approaches. Conclusion: The prevalence of dental trauma in the present study was high and occurred mainly in domestic settings. The upper central incisors were the teeth that suffered the most injuries. The presence of patients at follow-up visits was an important factor for the positive result in most cases.

Alterações bucais associadas à presença de atopia em crianças: um estudo transversal / Oral changes associated with the presence of atopy in children: a cross-sectional study

Resumo Introdução É por meio da interação entre ambiente, indivíduo, sua predisposição à atopia e exposição a alérgenos que surgem as doenças alérgicas. Em crianças atópicas, foi observada uma alta prevalência de padrão respirador bucal, assim como resposta positiva a testes alérgicos. Essas alterações respiratórias possuem uma associação com deformidades orofaciais, especialmente as maloclusões. Objetivo Identificar a frequência de crianças e adolescentes portadores de alergias e buscar uma provável associação entre atopia e maloclusão, traumatismos dentoalveolares e hábitos bucais viciosos. Material e método Foram avaliados prontuários de crianças e adolescentes atendidos em duas instituições particulares de ensino da cidade do Rio de Janeiro no período compreendido entre agosto de 2017 e julho de 2018. Foram coletados dados do prontuário relacionados ao histórico médico, odontológico e de alergias. Os dados foram analisados descritivamente e por meio do teste qui-quadrado (p<0,05). Resultado Um total de 136 prontuários foi considerado elegível para avaliação. Durante a anamnese, 49 responsáveis (36%) relataram histórico de alergias em suas crianças e adolescentes. A prevalência de hábitos bucais viciosos foi verificada em 87 pacientes (64%), sendo presente em 65,3% de crianças e adolescentes que apresentavam atopia (p<0,05). Conclusão A prevalência de alergias relatada nesta população foi de 34,6%, e foi observada ainda uma alta prevalência de hábitos bucais viciosos e traumatismos dentoalveolares nesses pacientes. Foram constatadas associações significativas entre presença de atopias e histórico de traumatismos dentários, maloclusão e hábitos viciosos, demonstrando haver correlação entre atopia e alguns aspectos de saúde oral.

Abstract Introduction Allergic diseases appear through the interaction between the environment, the individual, their predisposition to atopy and exposure to allergens. In atopic children there is a high prevalence of mouth breathers, as well as positive response to allergic prick tests. These respiratory changes have an association with orofacial deformities especially malocclusions. Objective To identify the frequency of children and adolescents that have atopies and search for a probable association between atopy and oral aspects like malocclusion and vicious oral habits. Material and method Medical records were taken of children and adolescents seen at two educational institutions in the city of Rio de Janeiro in the period between August 2017 and July 2018. Data were collected from medical records related to medical history, history of atopies and dental history. The data were transmitted descriptively through the chi-square test (p<0.05). Result A total of 136 records were considered eligible for evaluation. During the anamnesis, 49 (36.0%) parents reported a history of atopy in their children adolescents. The prevalence of vicious oral habits was found in 87 children and adolescents (64.0%), being presented in 65.3% of the patients who had atopy (p<0.05). Conclusion It can be observed that the prevalence of atopy reported in this population was 34.6% and there was also a high prevalence of vicious oral habits and dento-alveolar trauma in these patients. Relevant associations between the presence of atopies and history of dental trauma, malocclusion and the presence of oral vicious habits were observed, demonstrating a correlation between atopy and some aspects of oral health.

Periradicular lesions in HIV-infected patients attending the faculty of dentistry: clinical findings, socio-demographics status, habits and laboratory data - seeking an association.

OBJECTIVE: The purpose of this study was to estimate the prevalence of periradicular lesions in HIV-infected Brazilian patients and to assess the correlation of several factors with the periradicular status. METHOD: One hundred full-mouth periapical radiographs were evaluated. A total of 2,214 teeth were evaluated for the presence of periradicular lesions, caries lesions, coronal restorations, pulp cavity exposure and endodontic treatment. RESULTS: The prevalence of periradicular lesions was 46%. There were no significant differences between individuals with or without periradicular lesions with respect to their socio-demographic status, habits, laboratory data and route of HIV infection. However, the presence of a periradicular lesion was statistically correlated with the number of teeth with endodontic treatment (p = 0.018), inadequate endodontic treatment (p = 0.025), images suggesting pulp cavity exposure (p = 0.002) and caries lesions (p = 0.001). CONCLUSIONS: The prevalence of periradicular lesions in HIV-infected individuals was 46% and was not related to HIV infection.

Osteoradionecrosis in a Patient Submitted to Head and Neck Radiotherapy: A Case Report / Osteoradionecrosis en un Paciente Sometido a Radioterapia de Cabeza y Cuello: Reporte de un Caso

ABSTRACT: Radiotherapy applies ionizing radiation at predetermined doses for a limited period of time in order to destroy tumors. The oral cavity, which has a high rate of cell renewal, is affected by the side effects of radiotherapy including osteoradionecrosis (ORN). This condition occurs due to irradiated bone tissue that becomes devitalized and exposed in the oral cavity. Conservative therapies are recommended for ORN lesions that are not extensive or in an early stage. Surgical intervention is necessary for extensive areas affected by necrosis. This study reports a case of ORN in the left mandibular body which resulted in a pathological fracture. The treatment consisted of segmental mandibulectomy and the use of a reconstruction plate. Also, low-level laser therapy around bone exposure was performed. After surgery, the patient underwent 6 months of follow-up and was satisfied with the outcome. However, the patient died before control of ORN was achieved due to a heart attack.

RESUMEN: La radioterapia aplica radiación ionizante a dosis predeterminadas durante un período de tiempo limitado para destruir tumores. La cavidad oral, que tiene una alta tasa de renovación celular, se ve afectada por los efectos secundarios de la radioterapia, incluida la osteorradionecrosis (ORN). Esta condición se produce debido al tejido óseo irradiado que se desvitaliza y expone en la cavidad oral. Se recomiendan terapias conservadoras para las lesiones de ORN que no son extensas o en una etapa temprana. La intervención quirúrgica es necesaria para áreas extensas afectadas por necrosis. Este estudio reporta un caso de ORN en el cuerpo mandibular izquierdo que resultó en una fractura patológica. El tratamiento consistió en mandibulectomía segmentaria y el uso de una placa de reconstrucción. Además, se realizó una terapia con láser de bajo nivel alrededor de la exposición ósea. Después de la cirugía, el paciente se sometió a 6 meses de seguimiento y quedó satisfecho con el resultado. Sin embargo, el paciente falleció antes de que se lograra el control de ORN debido a un ataque cardíaco.

CONHECIMENTO SOBRE BEIJO NA BOCA DE ADOLESCENTES DE UM GRUPO DE ESCOLAS PRIVADAS DE NOVA IGUAÇU/RIO DE JANEIRO ­ ESTUDO PILOTO / KNOWLEDGE ABOUT KISSING IN THE MOUTH OF ADOLESCENTS FROM A GROUP OF PRIVATE SCHOOLS IN NOVA IGUAÇU / RIO DE JANEIRO - PILOT STUDY

Objetivo: Descrever os conhecimentos sobre o beijo na boca e sua possibilidade de transmissão de doenças infecciosas em um grupo de adolescentes de escolas privadas de Nova Iguaçu/Rio de Janeiro, através deste estudo piloto. Metodologia: Estudo seccional em que foi aplicado um roteiro de perguntas semi-estruturado autoaplicável em adolescentes (de 18 e 19 anos) de ambos os gêneros, pertencentes a três escolas da rede de ensino privado do município de Nova Iguaçu no Estado do Rio de Janeiro. Resultados: De um total de 100 adolescentes que participaram deste estudo, mais da metade eram solteiros e do gênero feminino (61%), apenas estudantes como ocupação (88% do total) e 96% já haviam beijado na boca. A amostra selecionada demonstrou características próprias, com a alta frequência do conhecimento da possibilidade de transmissão de doenças infecciosas pelo beijo na boca e saliva (71%), que possivelmente se confirmou pela baixa ocorrência de lesões após o ato do beijo e pela observação da boca do parceiro antes de beijar. Conclusão: A pratica do beijo na boca e o sexo oral devem ser temáticas consideradas na assistência fornecida a adolescentes. O uso de estratégias preventivas e o acesso às redes sociais podem contribuir para a redução de situações de risco advindos de situações de vulnerabilidade.

Aim: To describe the knowledge about the kiss on the mouth and its possibility of transmission of infectious diseases in a group of adolescents from private schools in Nova Iguaçu / Rio de Janeiro, through this pilot study. Methodology: Cross-sectional study in which a self-administered semi-structured question script was applied to adolescents (18 and 19 years) of both genders, belonging to three schools of the private school system of Nova Iguaçu, Rio de Janeiro State. Results: Of a total of 100 adolescents who participated in this study, more than half were single and female (61%), only students as occupation (88% of the total) and 96% had already kissed the mouth. The selected sample demonstrated its own characteristics, with the high frequency of the knowledge of the possibility of transmission of infectious diseases by kissing in the mouth and saliva (71%), which was possibly confirmed by the low occurrence of lesions after the kiss and the observation of the mouth. of the partner before kissing. Conclusion: The practice of kissing on the mouth and oral sex should be thematic considered in the care provided to adolescents. The use of preventive strategies and access to social networks can contribute to the reduction of risk situations arising from vulnerability situations. Keywords: mouth, infectious diseases, adolescent (s), health education, strategies and oral health

Topical effect of a medically prescribed pediatric antibiotic on dental biofilm: a cross-over, in situ study.

OBJECTIVE: This study aimed to investigate the possible topical effect of a broad-spectrum antibiotic on dental biofilm formed in situ in the absence or presence of sucrose. METHODS: A crossover study was conducted in three phases of 14 days each, during which 11 volunteers wore palatal devices containing 6 enamel blocks covered with meshes to allow biofilm formation. Dental blocks were extraorally submitted to a 20% sucrose solution at three different frequencies of exposure (0, 3 and 8 times/day), and to a suspension of amoxicillin/clavulanate potassium (A/CP) or a placebo (P) suspension at an 8-hour time interval application regimen. On the 14(th) day of each phase, biofilms were collected for microbiological (conventional culture) and molecular (Denaturing Gradient Gel Electrophoresis--DGGE) analyses. RESULTS: In the absence of sucrose exposure (SE) and at the 3-time daily frequency, dental biofilms treated with A/CP showed lower total biofilm weight and lower counts of total microbiota than the ones treated with P (p>0.05). A/CP presented higher counts of Candida spp. when compared with P in the presence of SE, especially at the 8-time daily frequency (p<0.05). Considering the DGGE analysis, the mean number of bands was higher for P (p>0.05), regardless of SE. However, DGGE profiles demonstrated large interindividual variability. CONCLUSION: Both conventional culture and DGGE have demonstrated some differences on total microbiota of dental biofilms when exposed to the A/CP or P suspensions, mainly in the absence of sucrose, which suggests a possible topical effect of the sugar-free A/CP suspension on dental biofilm.

Recent syphilis with oral manifestations: three case reports treated at a STD clinic / Sífilis recente com manifestação oral: relato de três casos atendidos em uma clínica de DST

Introduction: The occurrence of sexually transmitted infections with oral manifestations, such as syphilis, remains a challenge in the era of rapid tests associated with an adequate clinical evaluation in the patients' approach. Objective: To describe the clinical and laboratory aspects involved, from the diagnosis to prognosis, of three case reports of recent syphilis with oral manifestations attended at a university clinic in the city of Niteroi, Rio de Janeiro, Brazil. Case report: Three cases of recent syphilis with oral manifestations in the tongue region. The first one, a 38-year-old female patient who presented syphilis in regions of the body other than the oral cavity (case I); the second one, a 31-year-old male patient with oral ulcerative lesions with associated genital lesion (case II); and, finally, a 49-year-old female patient suspected of oral human papillomavirus (HPV) lesions, in which syphilis was confirmed after a long path to obtain her diagnosis (case III). All cases were laboratory tested at the time of diagnosis and received appropriate treatment and guidance. Conclusion: It was possible to observe through the present study that some situations need attention: evaluation of the oral cavity should occur concomitantly with the investigation of genital lesions; diagnosis hypothesis of occurrence of syphilis with oral manifestation should be considered in the clinical evaluation; oral lesions may present similar clinical manifestations, suggesting investigation of their possible infectious etiology.

Introdução: A abordagem das infecções sexualmente transmissíveis com manifestações orais, tais como a sífilis, ainda permanece um desafio na era dos testes rápidos associados à adequada avaliação clínica na assistência de pacientes. Objetivo: Descrever os aspectos clínicos e laboratoriais envolvidos, do diagnóstico ao prognóstico, de três casos clínicos de sífilis recente com manifestações orais atendidos em uma clínica universitária do município de Niterói, estado do Rio de Janeiro. Relato de caso: Trata-se de três casos de sífilis recente com manifestações orais na região de língua, que ocorreram em: uma paciente do sexo feminino, 38 anos, em que as manifestações da sífilis foram observadas em outras regiões do corpo e na cavidade oral (caso I); um paciente do sexo masculino, 31 anos, que apresentava lesões ulceradas orais com lesão genital associada (caso II); e, por fim, uma paciente do sexo feminino, 49 anos, sob suspeita de infecção pelo vírus do papiloma humano (HPV) oral, em que foi confirmada sífilis após percorrer um longo trajeto até o estabelecimento do seu diagnóstico (caso III). Todos os casos realizaram testes laboratoriais por ocasião do diagnóstico e receberam tratamento e orientação adequados. Conclusão: Foi possível observar pelo presente estudo algumas situações que necessitam de atenção: a avaliação da cavidade oral deve ocorrer de forma concomitante e sistemática com a investigação de lesões genitais; a hipótese diagnóstica de ocorrência de sífilis com manifestação oral deve ser considerada na avaliação clínica; lesões bucais podem apresentar manifestações clínicas similares a outras doenças, sugerindo investigação de sua possível etiologia infecciosa ou não.

Measurement of Distance Between the Mental Foramina using Cone-Beam Computed Tomography: A Pilot Study with a Possible Method for Planning Mandibular Implants

Objective: To identify the average number of dental implants that can be placed in the lower anterior region to support a fixed mandibular prosthesis based on the distance between the mental foramina, using a cone beam computed tomography (CBCT) scan through a new method of measurement. Material and Methods: Eighty-two CT scans from a total sample of 1,465 exams were selected. The method to measure the space between the foramina was developed using the BlueSky Plan3 software in Dicom format and the axial reconstruction views were chosen for measurements. Descriptive analysis of data was conducted categorical variables were compared using the χ2 test (p <0.05). Results: The mean age of individuals who underwent the scans was 63.51 ± 9.49 years old with a minimum and maximum age of 40 and 86 years old, respectively. The mean linear measurement between the foramina was 40.52 ± 3.92mm. In males the mean distance was 41.93 ± 3.98 mm, and for females it was 39.99 ± 3.80mm, with a significant difference between the means (p = 0.043). There was no positive association between the presence of the anterior loop and gender (p = 0.719). The results showed that the vast majority of subjects (n = 80) could be rehabilitated using a protocol with 4 implants of 3.3mm diameters. Conclusion: Seventy-seven patients would be able to receive protocols of 4 implants with diameters of 3.75 or 4.0mm, and only 4 subjects would be able to be rehabilitated with 6 implants with diameters of 3.75 mm according to the protocol originally described by Brånemark.

Identification of Enterococcus faecalis by PCR in saliva of pediatric patients / Identificação do Enterococcus faecalis por PCR em saliva de pacientes pediátricos

This study aimed to identify E. faecalis in saliva of patients that were divided into two groups: 10 patients with caries lesions and 10 caries-free patients. Material and methods: Saliva samples were collected with a sterile swab and inoculated in enterococcosel media for 48 hours. The positive samples were subcultured in broth agar - blood medium for storage and subsequent PCR analysis. The data were analyzed using the SPSS (÷2). Results: From the 20 cases included in the study, 3 were positive in the Enterococcosel medium, and both tests (culture and PCR) used confirmed that three of them belonged to the species E. faecalis. No samples were positive in Enterococcosel broth in the group of caries-free patients. From the three samples that were identified as Enterococcus in broth (positive bile esculin test), an amplified for E. faecalis PCR analysis (p > 0.005). Conclusion: Through the use of PCR, it was possible to identify the genus Enterococcus and the species E. faecalis in saliva of patients with carious lesions – the pathogen that may influence the prognosis of diseases of the oral cavity...

Este estudo objetivou identificar E. faecalis em saliva de pacientes que foram divididos em dois grupos: 10 pacientes com lesões de cárie e 10 livres de cárie. Material e métodos: Amostras de saliva foram coletadas com um swab estéril e inoculadas em meios Enterococcosel por 48 horas. As amostras positivas foram repicadas em meio de caldo de agar - sangue para armazenamento e análise de PCR subsequente. Os dados foram analisados utilizando o SPSS. Resultados: Dos 20 casos incluídos no estudo, três foram positivos no médio Enterococcosel e ambos os testes (cultura e PCR) utilizados confirmaram que três deles pertenciam à espécie E. faecalis. Nenhuma amostra foi positiva em caldo Enterococcosel no grupo de pacientes livres de cáries. A partir das três amostras que foram identificadas como Enterococcus em caldo (teste positivo esculina biliar), foram amplificados por análise de PCR para o E. faecalis (p>0.005). Conclusão: Através da utilização de PCR, foi possível identificar gênero Enterococcus e a espécie de E. faecalis em saliva de pacientes com lesões de cárie – o agente patogênico que pode influenciar o prognóstico de doenças da cavidade oral...
