Smoking in adolescents with cleft lip and/or palate: prevalence and associated factors.

OBJECTIVE: To assess the prevalence and factors associated with smoking in adolescents with cleft lip and/or palate. METHODS: This is a cross-sectional study, developed in a Brazilian public and tertiary hospital between November 2018 and August 2019. Adolescents aged between 12 and 19 years old, previously submitted to cheiloplasty and/or palatoplasty surgeries were included. Data collection was carried out through interviews, guided by questionnaires referring to sociodemographic issues, use and factors associated with smoking. For statistical analysis, Fisher's Exact Test, Chi-square, Student's t test and bivariate logistic regression were used, all with a significance level of 5% (p≤0.05). RESULTS: 102 adolescents participated. The prevalence of smoking was 20.6% (n=21). Having cleft lip and palate was associated with smoking (p=0.012). The bivariate analysis showed that not dating (p=0.001; OR=0.19) and owning a home (p=0.032; OR=0.33) were configured as protective factors for the act of being a smoker, while believing that smoking facilitates interaction with young people or with the group of friends (p=0.043; OR=2.95), having friends who use alcoholic beverages (p=0.002; OR=8.40), having friends who use drugs, except cigarettes (p=0.002; OR=5.33), use alcoholic beverages (p<0.001; OR=10.67) and sexual initiation (p<0.001; OR=7.00), were associated with being a smoker. CONCLUSIONS: From the knowledge of the profile of adolescents most vulnerable to tobacco use, it is possible to plan and implement educational and preventive actions.

RESUMO Objetivo: Avaliar a prevalência e os fatores associados ao tabagismo em adolescentes com fissura de lábio e/ou palato. Métodos: Estudo de corte transversal, desenvolvido em um hospital público e terciário brasileiro entre novembro de 2018 e agosto de 2019. Foram incluídos adolescentes com idade entre 12 e 19 anos, submetidos previamente às cirurgias de queiloplastia e/ou palatoplastia. A coleta de dados foi realizada por meio de entrevista, guiada por questionários referentes a questões sociodemográficas, uso e fatores associados ao tabagismo. Para a análise estatística, utilizaram-se os testes: exato de Fisher, qui-quadrado, t de Student e regressão logística bivariada, todos com nível de significância de 5% (p ≤ 0,05). Resultados: Participaram 102 adolescentes. A prevalência do tabagismo foi de 20,6% (n=21). Possuir fissura de lábio e palato associou-se ao tabagismo (p=0,012). A análise bivariada mostrou que não namorar (p=0,001; OR=0,19) e possuir habitação própria (p=0,032; OR=0,33) configuraram fatores de proteção para o ato de ser tabagista, enquanto acreditar que fumar facilita a interação com os jovens ou com o grupo de amigos (p=0,043; OR=2,95), ter amigos que usam bebida alcoólica (p=0,002; OR=8,40), ter amigos que usam drogas, exceto o cigarro (p=0,002; OR=5,33), usar bebida alcoólica (p<0,001; OR=10,67) e iniciação sexual (p<0,001; OR=7,00) associaram-se a ser tabagista. Conclusões: Pelo conhecimento do perfil dos adolescentes mais vulneráveis ao uso do tabaco, é possível planejar e programar ações educativas e preventivas.

Eficácia do propionato de clobetasol 0, 05 nas lesões ulceradas da cavidade bucal / Efficacy of 0.05% clobetasol propionate in ulcerated lesions of the oral cavity

O uso tópico de Propionato de Clobetasol 0,05% em solução aquosa para lesões ulceradas na cavidade bucal é pouco divulgado nacionalmente e tem sido pouco citado em traba-lhos científicos a respeito de sua eficácia, tempo de regressão da lesão e efeitos adversos. Portanto, o objetivo deste estudo foi avaliar retrospectivamente prontuários de pacientes que foram tratados de lesões ulceradas através do uso do Propionato de Clobetasol 0,05%, no ambulatório de estomatopatologia de uma Instituição, a fim de investigar sua eficácia. Foram selecionados prontuários de pacientes que apresentaram a alteração fundamental ulcerada ou erosiva e que fizeram o uso tópico de Propionato de Clobetasol 0,05%. A aná-lise retrospectiva foi feita por um examinador, que fez a seleção da amostra seguindo os critérios de inclusão e exclusão. Foram coletadas as informações: Idade, gênero, diagnós-tico da alteração; quantidade de lesão, tempo de uso, evolução da lesão, tempo exato de regressão e presença de reações adversas. Foram incluídos 17 prontuários, dos quais cinco eram de pacientes com lesões erosivas de líquen plano, três úlceras traumáticas, três lesões liquenóides, dois eritemas multiformes, uma alergia a lactose, uma afta e uma gengivite descamativa. Todos os casos apresentaram resolução da sintomatologia, porém as altera-ções clínicas permaneceram em seis casos, embora mais leves e assintomáticas. Não foi ob-servada nenhuma reação adversa registrada no prontuário. A análise estatística não apontou associação em relação ao sexo (teste Exato de Fisher; p=0,49; p>0,05). Não foi observada diferença estatística significativa na frequência das lesões (teste exato de Fisher; p= 0,85; p>0,05). O uso do Propionato de Clobetasol 0,05% prescrito por até cinco dias se mostrou eficaz no tratamento de lesões ulceradas da mucosa bucal, principalmente para o alívio sintomático, além disso, não revelou efeitos adversos.

The treatment of ulcerated lesions of the oral cavity is usually carried out using topical analgesic drugs, anti-inflammatory corticosteroids, and alcohol-free oral antiseptics. The topical use of 0.05% Clobetasol Propionate in aqueous solution for ulcerated lesions in the oral cavity is little publicized nationally and little mentioned in scientific studies regarding its effectiveness, lesion regression time, and adverse effects. Therefore, the objective of this study was to retrospectively evaluate the medical records of patients who were treated for ulcerated or erosive lesions, using Clobetasol Propionate 0.05%, in the stomatology clinic of an institution to investigate its effectiveness. Medical records of patients who presented the fundamental ulcerated alteration and made topical use of 0.05% Clobetasol Propionate were selected. An examiner selected the sample following the inclusion and exclusion cri-teria and performed the retrospective analysis. The types of information collected were age, gender, diagnosis of the disorder, amount of injury, time of use, the evolution of the injury, exact time of regression, and presence of adverse reactions. A total of 17 medical records were included, of which five were from patients with erosive lichen planus lesions, three traumatic ulcers, three lichenoid lesions, two multiform erythema, one lactose allergy, one cold sore, and one scaly gingivitis. All cases had their symptoms solved, but, in six cases, the clinical changes remained, although milder and asymptomatic. No adverse reaction was noted in the medical record. The statistical analysis showed no association in relation to gender (Fisher's exact test; p = 0.49; p> 0.05). There was no statistically significant diffe-rence in the frequency of injuries (Fisher's exact test; p = 0.85; p> 0.05). The use of 0.05% Clobetasol Propionate, prescribed for up to five days, proved effective in treating ulcerated lesions of the oral mucosa, mainly for symptomatic relief. Furthermore, it revealed no ad-verse effects.

Treatment of bisphosphonate-related osteonecrosis using platelet-rich plasma: microtomographic, microscopic, and immunohistochemical analyses.

The present study aimed to investigate the use of platelet-rich plasma (PRP) on tooth extraction sites in rats treated with bisphosphonates. Thirty Albinus Wistar male rats were administered 0.035 mg/kg zoledronic acid intravenously for 8 weeks, divided into four administrations with a 2-week interval between each application, after which their upper right central incisors were extracted to induce the development of bisphosphonate-related osteonecrosis of the jaw (BRONJ). The samples were divided into the following two groups: Group 1 (G1) underwent marginal resection of BRONJ followed by the use of PRP, while Group 2 (G2) underwent resection of BRONJ but without the use of PRP. The treatment groups were evaluated after 14, 28, and 42 days. Clinical, microtomographic, microscopic, and immunohistochemical (IHC) evaluations were performed. Microtomography results revealed no significant difference between the groups (p <0.05) in any time period. Histomorphometric analysis showed increased bone formation over time for both groups (p < 0.001). G1 demonstrated a greater amount of new bone formation than G2 at 28 and 42 days (p < 0.001), with G1 presenting greater vascularization and a slightly higher VEGF expression. For both groups, RANKL/OPG expression levels were sufficient as a parameter for indicating the rate of bone remodeling in a previously treated area of osteonecrosis groups. Taken together, our findings indicated that the use of PRP improves the resolution process of BRONJ.

Explanation for the signs and symptoms of tooth eruption: mast cells.

This study contributes to the understanding of the mechanisms associated with signs and symptoms of tooth eruption, by investigating the presence of mast cells in pericoronal tissues during the intraosseous (Group 1) and submucosal (Group 2) phases of eruption. We compared findings for these two groups with each other and with those for the oral mucosa (Group 3). In each group, 14 specimens were analyzed microscopically after hematoxylin and eosin staining and immunohistochemical analysis of c-Kit and tryptase expression. Results revealed that the number and density of mast cells is different in follicular tissues according to the eruption phase, which may mean that: 1) masticatory trauma of the oral mucosa and dental follicles in the submucosa may explain why reduced enamel epithelium exposes enamel to the cells of the connective tissue; 2) exposure of antigenic enamel proteins might correspond to the release of sequestered antigens, which may lead to the interaction of IgE and a greater number of mast cells in the region; and 3) the consequent degranulation and the local release of mediators, such as histamine, leukotrienes, prostaglandins, proteases, cytokines and growth factors, contribute to the understanding of signs and symptoms associated with tooth eruption.

A new technique for tongue brushing and halitosis reduction: the X technique.

The tongue is one of the primary sources of halitosis. The manual or mechanical removal of biofilm is known to decrease oral malodor. OBJECTIVE: To evaluate a new tongue hygiene technique hereby referred to as "the X technique" and its effects on both halitosis and the number of microorganisms based on microbiological parameters and diagnostic features of the breath. MATERIAL AND METHODS: The study included thirty patients divided into a control group (patients without systematized guidelines of lingual hygiene, but who performed the mechanical cleaning of tongue dorsum, each in its own way), the 3R group (instructed to perform the movements of the X technique for 3 repetitions at each brushing), and the 6R group (instructed to perform 6 repetitions of the technique at each brushing). After two weeks, a new data collection was performed. RESULTS: Patients in the 6R group presented the lowest score on the organoleptic assessment scale at the second consultation, followed by the 3R group and the controls. Regarding the self-perception of breath by the method of Visual Analog Scale (VAS), the control group did not perceive improvements in oral malodor; the results of the 3R group and the 6R group were similar. CONCLUSION: These results indicate that the X technique improves both measurements and perceptions of halitosis. Microbiological analyses revealed greatest reduction in the 6R group. The findings show that the X technique reduces both organoleptic scores and the number of bacterial colonies, and improves users' perceptions of their breath.

Resumo Para contribuir com a compreensão dos mecanismos relacionados à sintomatologia e aos sinais associados à erupção dentária, investigou-se a presença de mastócitos nos tecidos pericoronários na fase intraóssea (Grupo 1) e submucosa (Grupo 2), comparando-os entre si e com a mucosa bucal (Grupo 3). Em cada grupo, 14 espécimes foram analisados microscopicamente em cortes corados com hematoxilina e eosina, e imunocitoquimicamente marcados com Ckit e Triptase. Pelos resultados obtidos, concluiu-se que a quantidade/densidade dos mastócitos é diferente nos tecidos foliculares de acordo com a fase de erupção, o que permite inferir que: 1) O traumatismo decorrente da mastigação sobre o conjunto "mucosa bucal com o folículo pericoronário na submucosa" pode explicar porque o epitélio reduzido exporia o esmalte às células do tecido conjuntivo; 2) A exposição das proteínas do esmalte com propriedades antigênicas corresponderia à liberação de antígenos sequestrados que levariam à interação de IgE e mastócitos em número aumentado na região; e 3) A consequente degranulação e liberação de mediadores no local, como histamina, leucotrienes, prostaglandinas, proteases, citocinas e fatores de crescimento, contribuem para a compreensão dos sinais e sintomatologia atribuídos à erupção dentária.

Qualidade de vida dos cuidadores de crianças de 0 a 12 anos atendidas na clínica de terapia ocupacional / Quality of Life of Caregivers of Children from 0 to 12 Years Attended in the Occupational Therapy Clinic

Introdução: Atualmente a definição de qualidade de vida mais utilizada é a descrita pela Organização Mundial da Saúde (OMS) em 1998, que relaciona o termo com a "percepção do indivíduo de sua posição na vida no contexto cultural e sistema de valores em que vivem e sobre os seus objetivos, expectativas, padrões e preocupações". Já o cuidador, é todo aquele que se responsabiliza pelo ato de cuidar de um indivíduo suprindo suas necessidades. Objetivo: avaliar a qualidade de vida dos cuidadores de crianças de 0 a 12 anos atendidas na Clínica de Terapia Ocupacional da Universidade do Sagrado Coração. Métodos: tratou-se de uma pesquisa descritiva-exploratória com caráter quantitativo que utilizou para a coleta de dados um questionário sociodemográfico construído pela autora e o Questionário de Qualidade de Vida ­ SF ­ 36. Resultados: Observou-se prevalência de cuidadores do sexo feminino entre 31 a 40 anos e crianças do sexo masculino entre 7 a 9 anos, sem hipótese diagnóstica definida. Além disso, observouse que a soma dos resultados de todos os cuidadores na avaliação por meio do Questionário de Qualidade de Vida ­ SF 36 atingiu escores acima de 50, podendo considerar como "muito boa", com destaque para o domínio Capacidade Funcional com o melhor escore e Vitalidade com o pior. Conclusão: Apesar disso, nenhum escore atingiu 100, deixando transparecer que mesmo o resultado tendo sido significativo, existem intercorrências que afetam de alguma maneira a qualidade de vida desses cuidadores.

Introduction: Currently the adopted definition of quality is that provided by the World Health Organization (WHO) in 1998 that express it as "the individual´s perception to its life position in the cultural content and value system in which they live and on their goals, expectations, standards and concerns. In its turn, the definition of caregiver means every one that is liable for the act of taking care of an individual attending to your needs. Objectives: to evaluate the quality of life of caregivers of children 0 to 12 met in the Clinic of Occupational Therapy the University Sagrado Coração. Methods: This was a descriptive-exploratory quantitative study using for data collection a sociodemographic questionnaire constructed by the author and the Questionnaire of Quality of Life - SF 36. Results: it was observed a prevalence of female caregivers between 31 to 40 years and male children between 7 to 9 years without a defined diagnostic hypothesis. In addition, it was observed that the sum of the results of all the caregivers in the assessment through the Questionnaire of Quality of life - SF 36 has reached scores above 50 what can be considered "very good", with the featured pair to domain Functional Capacity with the best score, and Vitality with the worst. Conclusion: Despite some good findings, no score has reached 100, revealing that , despite the significant results, there are still aspects that may affect the quality of life these caregivers.

Is quality of life affected by temporomandibular disorders?

OBJECTIVE: To determine the impact of temporomandibular disorders in quality of life. METHODS: A total of 102 volunteer patients (68 female) aged 19 to 86 years, who sought medical care in health clinics of the university and were evaluated in the period from September to December 2013. The subjects were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders, using a mechanical algometer (Palpeter®) with standardized pressure of 0.5 and 1.0kg, and Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) questionnaire, to assess quality of life. The data were tabulated for statistical analysis and the variables were correlated with the clinical findings of the temporomandibular disorders and quality of life. RESULTS: Fifty percent of patients were positive for temporomandibular disorders and 39.2% classified as myofascial pain group. The temporomandibular disorder group was significantly associated with uncomfortable bite (p=0.0000), temporomandibular joint clicking (p=0.0001) and tooth clenching (p=0.0001). The Mann Whitney test used to analyze the SF-36 revealed that the domains of pain (mean score of 47.80%; p<0.0001) and mental health (62.67%; p<0.05) were strongly associated with temporomandibular disorders. CONCLUSION: The quality of life of individuals with temporomandibular disorders was negatively affected by the presence of pain and mental health disorders.

West Syndrome: Report of Clinical Case: 9 Years of Follow-up / Síndrome de West: Relato de Caso: 9 anos de Acompanhamento

ABSTRACT West Syndrome is one of the rare and severe childhood epilepsies, starting in the first year of life and having an uncertain etiology. Even if some of the symptoms are missing, a triad of them defines West Syndrome, including epileptic spasms, arrest or regression of psychomotor development, and hypsarrhythmia on interictal electroencephalography. The objective of this study was to obtain updated data on West Syndrome literature and report a clinical case of a patient with the medical diagnosis of this syndrome, with gastrostomy feed tube, and clinical pattern of spastic quadriplegia. Initial clinical examination showed prolonged retention of deciduous teeth, periodontal disease, poor oral hygiene, mouth breathing, deep palate, anterior open bite, tongue interposition between the dental arches, and low caries experience. Over 9 years the patient presented complications in their sistemicas conditions, with need for gastrostomy and many periods of hospitalization that determined periods of absence for the dental monitoring. Despite this, currently his oral health condition is good and stable. Dental care for people with disabilities should be developed, encouraged and continuously extended, in agreement with the constitutional principles of human dignity and the rights for health and equality.

RESUMO A Síndrome de West é uma rara e severa forma de epilepsia da infância, com início no primeiro ano de vida e etiologia ainda não definida. Mesmo com a ausência de alguns sintomas, a tríade que define a Síndrome de West é a presença de espasmos, retardo no desenvolvimento psicomotor e a presença da hypssarritmia no eletroencefalograma. O objetivo deste estudo foi a obtenção de dados atualizados na literatura sobre a Síndrome de West e relatar um caso clínico de um paciente com diagnóstico médico dessa síndrome, com gastrostomia e padrão clínico de quadriplegia espástica. No exame clínico inicial observou-se retenção prolongada de dentes decíduos, doença periodontal, padrão pobre de higiene bucal, respiração bucal, palato profundo, mordida aberta anterior, interposição de língua entre os arcos dentais e baixa experiência de cárie. Ao longo de 9 anos o paciente apresentou complicações nas suas condições sistêmicas, com necessidade e realizar gastrostomia e com muitos períodos de internação. Apesar disto, atualmente sua condição de saúde bucal é boa e estável. Os cuidados odontológicos para pessoas com deficiência devem ser desenvolvidos, encorajados e estendidos continuamente, de acordo com os princípios constitucionais da dignidade humana e os direitos de saúde e de igualdade.

Premaxilla: up to which age it remains separated from the maxilla by a suture, how often it occurs in children and adults, and possible clinical and therapeutic implications: Study of 1,138 human skulls

ABSTRACT Objective: To evaluate topographic and temporal aspects of premaxillary bone and premaxillary-maxillary suture, since they are fundamental anatomical elements little explored clinically. Methods: 1,138 human dry skulls were evaluated, of which 116 (10.19%) of the specimens were children, and 1,022 (89.81%) were adults. The skulls were photographed and the percentage of premaxillary-maxillary suture opening was determined. Subsequently the data were tabulated and submitted to statistical analysis, adopting a level of significance of 5%. Results: The progression of premaxillary suture closure from birth to 12 years of age was 3.72% per year. In 100% of the skulls up to 12 years, the premaxillary-maxillary suture open in the palatal region was observed, while 6.16% of adults presented different degrees of opening. Conclusions: The premaxilla exists in an independent way within the maxillary complex and the presence of the premaxilla-maxillary suture justifies the success of anteroposterior expansions to stimulate the growth of the middle third of the face, solving anatomical and functional problems.

RESUMO Objetivo: avaliar aspectos topográficos e temporais do osso pré-maxilar e da sutura pré-maxilar/maxilar, por serem elementos anatômicos fundamentais pouco explorados clinicamente. Métodos: foram avaliados 1.138 crânios secos humanos, sendo 116 (10,19%) dos espécimes crianças e 1.022 (89,81%) adultos. Os crânios foram fotografados e determinou-se a porcentagem de abertura da sutura pré-maxilar/maxilar. Posteriormente, os dados foram tabulados e submetidos a análise estatística, adotando-se nível de significância de 5%. Resultados: a progressão de fechamento da sutura pré-maxilar/maxilar do nascimento aos 12 anos de idade foi de 3,72% ao ano. Em 100% dos crânios até 12 anos, observou-se a sutura pré-maxilar/maxilar aberta na região palatina, enquanto 6,16% dos adultos apresentavam diferentes graus. Conclusões: a pré-maxila existe de forma independente dentro do complexo maxilar e a presença da sutura pré-maxilar / maxilar justifica o sucesso de expansões anteroposteriores para estimular o crescimento do terço médio da face, solucionando problemas anatômicos e funcionais.

Influência da oleosidade resultante da lubrificação da caneta de alta rotação na adesão da resina composta ao esmalte / Influence of oil contamination resulting from lubrication of high-speed handpieces in the bonding of composite resin to enamel

A restauração de dentes por sistemas adesivos é rotina em odontologia. O tratamento do esmalte inicia-se pela profilaxia e asperização dos prismas. A manobra é feita com brocas adaptadas à canetas de alta ou baixa rotação as quais devem ser lubrificadas frequentemente. Diversos fatores podem provocar falhas nas restaurações, entre eles a contaminação por oleosidade. A proposta do trabalho foi verificar a influência da lubrificação das pontas de alta rotação na adesão de resinas compostas ao esmalte. Foram confeccionados 30 corpos de provas, constituídos de cilindros de PVC, nos quais se incluiu fragmento da superfície vestibular de dente bovino em resina acrílica autopolimerizável, de maneira paralela ao solo, com área suficiente para a colagem de braquete de 9 mm2. A amostra foi dividida em três grupos de 10. No primeiro (A), cada braquete foi colado de maneira convencional com uma asperização prévia do esmalte realizada com caneta sem lubrificação. No segundo (B), foi realizada asperização com caneta lubrificada e pré-acionada por 30 segundos. E no terceiro (C), a asperização foi feita imediatamente após a lubrificação. Cada braquete foi submetido ao teste de tração. Todas as falhas foram coesivas, apresentando valores médios de 73,18N para o grupo A, 75,90N para o B e 91,45N para o C. O tratamento estatístico não mostrou diferença significativa entre os grupos. De acordo com o método instituído não houve influência da lubrificação das pontas de alta rotação na adesão de resinas compostas ao esmalte (AU).

The use of adhesive systems is a routine procedure in restorative dentistry. Enamel treatment starts with prophylaxis and abrasion of enamel prisms. This is performed using drills adapted to high or slow speed handpieces which must be frequently lubricated. Many factors may produce failure in tooth restoration, among them is the contamination by oil. The purpose of this study was to assess the influence of high speed handpiece lubrication in bond strength of composite resin to enamel. Thirty specimen were made constituted of PVC cylinders, in which were included fragments of the vestibular surface of the bovine tooth in self-polymerized acrylic resin parallel to the floor with sufficient area for bonding the 9 mm2 bracket. The samples were divided randomly into three groups of 10. In the first group (A), the bracket was bonded using the conventional way and enamel abrasion was previously performed with an unlubricated handpiece. In the second one (B), abrasion was performed with a lubricated handpiece which was run on air for 30 seconds and in the third group (C), abrasion was made immediately after lubrication. A tensile test was carried out for each bracket. All failures were cohesive with mean values of 73,18N (group A), 75,90N (group B) and 91,45N (group C). Statistical tests detected no significant differences between the groups.

Is quality of life affected by temporomandibular disorders? / A disfunção temporomandibular afeta a qualidade de vida?

ABSTRACT Objective To determine the impact of temporomandibular disorders in quality of life. Methods A total of 102 volunteer patients (68 female) aged 19 to 86 years, who sought medical care in health clinics of the university and were evaluated in the period from September to December 2013. The subjects were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders, using a mechanical algometer (Palpeter®) with standardized pressure of 0.5 and 1.0kg, and Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) questionnaire, to assess quality of life. The data were tabulated for statistical analysis and the variables were correlated with the clinical findings of the temporomandibular disorders and quality of life. Results Fifty percent of patients were positive for temporomandibular disorders and 39.2% classified as myofascial pain group. The temporomandibular disorder group was significantly associated with uncomfortable bite (p=0.0000), temporomandibular joint clicking (p=0.0001) and tooth clenching (p=0.0001). The Mann Whitney test used to analyze the SF-36 revealed that the domains of pain (mean score of 47.80%; p<0.0001) and mental health (62.67%; p<0.05) were strongly associated with temporomandibular disorders. Conclusion The quality of life of individuals with temporomandibular disorders was negatively affected by the presence of pain and mental health disorders.

RESUMO Objetivo Determinar o impacto das disfunções temporomandibulares na qualidade de vida. Métodos Foram incluídos 102 pacientes voluntários (68 mulheres) com idades entre 19 e 86 anos, que buscaram atendimento médico nas clínicas de saúde da universidade e foram avaliados no período de setembro a dezembro de 2013. Os pacientes foram examinados segundo os Critérios Diagnósticos para Pesquisa em Disfunções Temporomandibulares, usando um algômetro mecânico (Palpeter®) com pressão padronizada de 0,5 e 1,0kg e o questionário Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), para avaliação da qualidade de vida. Os dados foram tabulados para análise estatística, e as variáveis foram correlacionadas com os achados clínicos das disfunções temporomandibulares e da qualidade de vida. Resultados Metade dos pacientes foi positiva para disfunções temporomandibulares, sendo 39,2% deles classificados como grupo de dor miofascial. O grupo de disfunções temporomandibulares foi significativamente associado ao desconforto ao morder (p=0,0000), à crepitação da articulação temporomandibular (p=0,0001) e ao apertar dos dentes (p=0,0001). O teste de Mann-Whitney usado para analisar o SF-36 revelou que os domínios da dor (pontuação média de 47,80%; p<0,0001) e saúde mental (62,67%; p<0,05) estavam fortemente associados às disfunções temporomandibulares. Conclusão A qualidade de vida de indivíduos com disfunções temporomandibulares foi afetada negativamente pela presença da dor e de transtornos de saúde mental.

Radiographic Findings in Patients with Medication-Related Osteonecrosis of the Jaw.

A retrospective study was conducted of the records and panoramic radiographs of 35 patients treated with bisphosphonates (BP) and diagnosed with MRONJ. Panoramic radiography was used for evaluation, by two examiners, the following findings were subject of search: osteolysis (OT), cortical bone erosion (EC), bone sclerosis focal (FS) and diffuse (DS), bone sequestration (BS), thickening of lamina dura (TD), prominence of the inferior alveolar nerve canal (IAN), persisting alveolar sockets (SK), and the presence of a pathological fracture (PF). Medical information and staging were also recorded in order to correlate with radiographic findings. Bone sclerosis was the most frequent alteration, followed by OT and TD. The mandible was more affected than the maxilla. There was no significant difference between genders or significant correlation between the number of injuries with age and duration of BP usage. Considering the association between the radiographic findings and MRONJ staging, EC was predominant in stage 3 and DS in stage 2. IAN and PF demonstrated greater association with stage 3. In conclusion, the higher the clinical staging, the greater the severity of the bone alteration. Panoramic radiographic examination is a useful screening tool in patients submitted to antiresorptive therapy.

Higienização bucal em pacientes com deformidades nas mãos: uso de adaptador para escova dental

Avaliar o efeito do uso de uma adaptação para escova dental em indivíduos afetados pela hanseníase com garra e avaliar sua contribuição na higiene bucal. Sujeitos e método: estudo realizado no Instituto Lauro de Souza Lima, com amostra de dez pacientes com idade acima de 18 anos, apresentando garra ulnar, ou garra ulnar mediano no membro dominante, entre 2013 e 2016. Foram realizadas a identificação dos pacientes, de seu perfil social e da forma clínica da hanseníase e a análise da higienização bucal pelo Índice de Higiene Oral Simplificado (IHO-S). Cada componente desse índice é avaliado em uma escala de 0 a 3. O resultado do IHO-S é dado pela média dos pontos de cada dente, assim classificados: 0 a 1 ­ higiene satisfatória; 1,1 a 2 ­ higiene regular; 2,1 a 3 ­ higiene deficiente. Resultados: o IHO-S dos pacientes foi medido em três momentos: antes da entrega do adaptador; uma semana de uso contínuo do adaptador, 15 dias de uso contínuo do adaptador. Observaram-se valores menores da média e mediana do IHO-S com o uso do adaptador, de acordo com o tempo. O teste estatístico ANOVA confirmou a diferença significativa entre os grupos (p = 0,002196). O teste Tukey registrou a diferença do 1o momento em relação ao 2o (p = 0,02509) e ao 3o (p = 0,002199); não houve diferença estatística significativa entre o 2o e o 3o momentos. O teste de Kruskal-Wallis confirmou a diferença significativa entre os grupos (p = 0,005887). Conclusões: a tecnologia assistiva pode gerar melhora na capacidade funcional. Mesmo considerando o pequeno universo deste estudo, conclui-se que as adaptações podem contribuir para a melhora da qualidade de vida e também para a melhor qualidade da higiene bucal de tal população.

Prevalência de lesões bucais em crianças de 6 a 12 anos / Prevalence of oral lesions in children 6 to 12 years

Introdução: na literatura existem poucos levantamentos sobre alterações bucais pediátricas, uma vez que estes apresentam prevalências em faixas etárias mais abrangentes, incluindo jovens ou adultos. Objetivo: apresentar a prevalência das alterações bucais em tecidos moles que mais acometem crianças entre 6 e 12 anos de idade. Método: estudo prospectivo de identificação de lesões bucais da população infantil atendida na Clínica de Odontopediatria, da Faculdade de Odontologia da Universidade do Sagrado Coração, no período de outubro de 2012 a julho de 2013. Neste período, foram atendidas 129 crianças, sendo que 13 (10%) apresentaram alguma manifestação bucal em tecidos envolvendo tecidos moles. Os dados foram registrados por um único examinador em planilha própria, constando identificação do paciente, estado geral, tamanho, aspecto e localização da alteração, sintomas, tempo de instalação, tempo de recuperação, provável diagnóstico e tratamentos odontológicos realizados. Resultados e Discussão: as alterações bucais registradas foram: fístula/abscesso no rebordo alveolar (46,1%); estomatite herpética primária (15,4%); úlcera aftosa (15,4%); herpes simples recorrente (7,7%); língua fissurada (7,7%) e alveólise (7,7%). A localização mais frequente das alterações bucais registradas foi a mucosa alveolar superior (38,5%), seguida da mucosa alveolar inferior (23,1%), lábio superior direito (15,4%), maxila anterior (7,7%), rebordo gengival alveolar superior (7,7%) e dorso da língua (7,7%). A prevalência encontrada neste estudo prospectivo corrobora com outros levantamentos realizados na população infantil. Conclusão: é importante que os profissionais da área da saúde, especialmente o cirurgião-dentista, tenham o conhecimento da prevalência das principais lesões bucais em crianças para que estejam mais preparados para diagnosticá-las e tratá-las.

Introduction: in the literature there are few surveys of pediatric oral lesions, since these have prevalence in wider age groups, including young people or adults. Objective: present the prevalence of oral manifestations in soft tissues that most affect children between 6 and 12 years old. Methods: prospective study of oral lesions identification of children attendances at the Clinic of Pediatric Dentistry, Faculty of Dentistry, University of the Sacred Heart, from October 2012 to July 2013. During this period, 129 children were treated, and 13 (10%) had some oral manifestation in tissues surrounding soft tissues. Data were recorded by a single examiner at a specific note, consisting of patient identification, general condition, size, appearance and location of the oral manifestation, symptoms, installation time, recovery time, possible diagnosis and conducted dental treatments. Results and Discussion: Oral diseases recorded were: fistula/abscess alveolar (46.1%); primary herpetic stomatitis (15.4%), aphthous ulcer (15.4%), recurrent herpes simplex (7.7%), fissured tongue (7.7%) and alveolisys (7.7%). The most frequent location of oral abnormalities recorded was the superior alveolar mucosa (38.5%), followed by the inferior alveolar mucosa (23.1%), right upper lip (15.4%), anterior maxilla (7.7%), gingival superior alveolar (7.7%) and dorsum of the tongue (7.7%). The prevalence found in this prospective study corroborates other surveys in children. Conclusion: It is important that health professionals, especially the dentist, have knowledge of the prevalence of oral lesions in children in order to be better prepared to diagnose and treat them.

Oral squamous cell carcinoma: survival, recurrence and death / Carcinoma de células escamosas da boca: sobrevida, recidiva e óbitos

This paper was based in data survey from macro and microscopic oral lesions characteristics, personal data and medical history of patients diagnosed with oral squamous cell carcinoma in the Lab of Pathological Anatomy from the Federal University of Alfenas from January 2000 to December 2010, establishing comparative parameters among clinical data, type of treatment, recurrence, survival and anatomic pathological characteristics of the lesions. Were analyzed the histopathological reports, dental and hospital records. The highest incidence was in white men, age between 50 and 60 years, married, with low education and socioeconomic levels. The beginning of treatment occurred in average 67 days after the histopathological diagnosis. The estimated survival of patients at five years was 42%. The consumption of alcohol and tobacco and the occurrence of metastasis were statistically significant for the increase of recurrence and lethality.

O estudo realizou levantamento das características macro e microscópicas das lesões bucais, dados pessoais e históricos dos pacientes diagnosticados com carcinoma de células escamosas da boca no Laboratório de Anatomia Patológica da Universidade Federal de Alfenas entre janeiro de 2000 e dezembro de 2010. Estabeleceram-se parâmetros comparativos entre os dados clínicos, tipo de tratamento, recidivas, sobrevida e características anatomopatológicas das lesões. Foram analisados os laudos histopatológicos e os prontuários odontológicos e hospitalares. A maior incidência ocorreu em homens brancos, com idade entre 50 e 60 anos, casados, com baixa escolaridade e nível socioeconômico. O início do tratamento ocorreu, em média, 67 dias após o diagnóstico histopatológico. A sobrevida estimada dos pacientes aos cinco anos foi de 42%. O consumo de álcool e tabaco e a presença de metástases foram estatisticamente significativos para o aumento da recidiva e da letalidade.
