ABSTRACT

Abstract The aim of this study was to evaluate the effect of different die materials used in the indirect resin composite restorative technique on the fracture resistance and failure mode of restored molars and compare it with the direct resin composite restorative technique. Two flexible die silicone materials for dental models (Die Silicone - Voco and Scan die - Yller) and a type IV dental stone material (Fujirock EP - GC) were evaluated. Sixty third molars were selected and divided into four groups: indirect resin composite restoration - Die silicone (IRCR-DS); indirect resin composite restoration - Scan die (IRCR-SD); indirect resin composite restoration - Fujirock EP (IRCR-FR), and direct resin composite restoration (DRCR). Class II MOD cavities were prepared with 5 mm of buccolingual width and depth. The specimens were restored and subjected to an axial compression load until fracture, and the data were analyzed by one-way ANOVA and Tukey's HSD test (α=.05). The fracture mode was classified into restorable and unrestorable fractures. Fracture resistance values were influenced by the die material used for the IRCR fabrication and by the restorative technique (p<.001). Fracture resistance mean values and standard deviation were: IRCR-DS: 1835.5 ± 324.0 A; IRCR-SD: 1732.5 ± 384.1 AB; IRCR-FR: 1419.3 ± 318.8 BC; and DRCR: 1100.6 ± 224.9 C. Restorable fracture was more prevalent. IRCR with flexible die casts promoted higher fracture resistance and lower prevalence of unrestorable fractures.

ABSTRACT

The individuals with Hansen's disease experience situations of prejudice that, together with stigma and discrimination, culminate in social isolation and restrictions in social relationships. The aim of this study was to assess the perception of leprosy patients about their quality of life. This is a cross-sectional, quantitative study, whose convenience sample consisted of 94 leprosy patients, undergoing treatment, who attended health units in the city of Cuiabá, MT, Brazil. A structured questionnaire with sociodemographic data and information about the patient's knowledge about leprosy, prejudice, self-esteem and quality of life, was applied between April and August 2018.The results showed in the investigated population a predominance of males (55.3%), individuals with high school education (28.7%) and with an income ranging from 1 to 3 minimum wages (67%).The interviewees pointed out the side effects (44.7%) and the duration period (28.7%) as the greatest difficulty in the treatment. Most of the investigated (72.3%) had great knowledge about the disease, among which 26.6% had already suffered the leprosy reaction.40.4% of individuals were depressed and sad, and 69.1% had problems in employment after the diagnosis of the disease. When the quality of life was investigated, 45.7% of leprosy patients classified the domains evaluated between bad and very bad. Physical pain was associated with 43.7% of the individuals being unable to perform daily tasks. It can be concluded that leprosy causes suffering beyond pain and discomfort, with great social and psychological impact. (AU)


Os pacientes com hanseníase vivenciam situações de preconceito que, com o estigma e a discriminação, culminam para o isolamento social e a restrição dos relacionamentos sociais. O objetivo do presente estudo foi avaliar a percepção do paciente com hanseníase sobre sua qualidade de vida. Trata-se de um estudo transversal, quantitativo, cuja amostra de conveniência foi composta por 94 pacientes hansenianos, em fase de tratamento, que frequentavam as Unidades de Saúde do município de Cuiabá/MT, Brasil. Um questionário estruturado com dados sociodemográficos e informações sobre o conhecimento do paciente sobre a hanseníase, preconceito, autoestima e qualidade de vida, foi aplicado entre abril e agosto de 2018. Os resultados mostraram, na população investigada, um predomínio de indivíduos do sexo masculino (55,3%), com ensino médio completo (28,7%) e com renda entre 1 e 3 salários mínimos (67%). Os entrevistados apontaram como maior dificuldade do tratamento os efeitos colaterais (44,7%) e o período de duração (28,7%). A maioria dos investigados (72,3%) apresentava grande conhecimento sobre a doença, dentre os quais 26,6% já haviam sofrido a reação hansênica. 40,4% dos indivíduos encontravam-se deprimidos e tristes e 69,1%, tiveram problemas no emprego após o diagnóstico da doença. Quando a qualidade de vida foi investigada, 45,7% dos hansenianos classificaram os domínios avaliados entre ruim e muito ruim. A dor física foi associada ao impedimento do desempenho das tarefas diárias por 43,7% dos indivíduos. Pode-se concluir que a hanseníase causa sofrimento aos indivíduos que ultrapassa a dor e o mal-estar estritamente vinculados ao prejuízo físico, com grande impacto social e psicológico. (AU)

ABSTRACT

Abstract Dental trauma is considered a complication in oral health, which has attracted the attention of researchers, as its prevalence has increased in recent years. Dental trauma in primary dentition can lead to early tooth loss and impairment of permanent successor teeth, depending on the stage of development of the tooth germ. The aim of the present study was to describe a clinical case of a 4-year-old child who was referred to a pediatric dentist after dental trauma and early loss of deciduous teeth. During the anamnesis, it was observed that the upper deciduous teeth (#51 and #61) were affected by successive traumas, resulting in the early loss of the affected teeth. Nance arch device with a tube-bar system was selected to restore function and aesthetics to the child, while the eruption of the successor permanent teeth was monitored. During the follow-up period, a delay in the eruption of #21 tooth was observed, and ulectomy of the region was indicated to allow the tooth eruption and the proper alignment of the central incisors, which occurred after 5 months of the surgical procedure. Through this report it was possible to conclude that the early diagnosis and the long-term periodic control of traumatic dental lesions in the primary dentition are of fundamental importance to prevent and minimize the damages that can occur to the permanent dentition.

Resumo O traumatismo dentário é considerado uma complicação à saúde bucal que vem chamando a atenção de pesquisadores, pois sua prevalência tem aumentado nos últimos anos. O trauma dentário na dentição decídua pode ocasionar a perda precoce dos dentes, e comprometimento dos dentes sucessores permanentes, dependendo do estágio de desenvolvimento do germe dentário. O objetivo do presente estudo foi descrever um caso clínico de uma criança de 4 anos de idade que foi encaminhada ao odontopediatra após traumatismo dentário e perda precoce de dente decíduo. Durante a anamnese, foi observado que os dentes decíduos incisivos superiores (#51 e #61) foram afetados por sucessivos traumas, resultando na perda precoce dos dentes afetados. O dispositivo arco de Nance com sistema do tipo tubo-barra foi selecionado para devolver função e estética à criança, enquanto a irrupção dos dentes permanentes sucessores foi acompanhada. Durante consulta de controle, um atraso na erupção do dente #21 foi observado e a ulectomia da região foi indicada para permitir a irrupção do dente e o alinhamento adequado dos incisivos centrais, que ocorreu após 5 meses do procedimento cirúrgico. Por meio do presente relato foi possível concluir que o diagnóstico precoce e o controle periódico a longo prazo das lesões dentárias traumáticas na dentição decídua são de fundamental importância para prevenir e minimizar os prejuízos que podem ocorrer à dentição permanente.

ABSTRACT

The aim of this study was to evaluate the association of oral parafunctions with the presence of signs and symptoms of craniomandibular disorder in children with cleft lip and palate (CLP). A cross-sectional study was performed in which one hundred and eighty-eight children with CLP and absence of associated syndromes or malformations were investigated. During clinical examination, the presence of wear facets and dental occlusion were observed and palpation was performed in the temporomandibular joint region (TMJ) and orofacial musculature . The children and their guardians were interviewed regarding the presence of oral parafunctional habits (bruxism, the act of biting the lips and/or cheeks, nail biting, sucking of fingers and pacifiers) and signs and symptoms of craniomandibular dysfunction (headache, ear and/or neckache, tiredness or crack in the TMJ during mouth opening and chewing movements). The data were analyzed by means of absolute and relative frequency measurements, and bivariate analysis using Pearson's chi-square test and likelihood ratio test were performed, considering the significance level of 5%. A higher prevalence of cleft lip and palate type (76.0%) and the presence of malocclusion (61.7%) was observed, highlighting the anterior crossbite (58.7%) and midline deviation (48.9%). There was a higher occurrence of teeth grinding (40.4%), onychophagy (28.7%) and biting lips and/or cheeks (28.7%). Onychophagia was associated with headache (p <0.05) and with pain or cracking during mouth opening (p <0.05). It was concluded that parafunctional oral habits may be associated with signs and symptoms of craniomandibular disorder in children with cleft lip and palate.


O objetivo do estudo foi avaliar a associação de parafunções orais com sinais e sintomas da disfunção craniomandibular em crianças com fissuras labiopalatinas (FLP). Um estudo transversal foi realizado, no qual cento e oitenta e oito crianças com FLP e ausência de síndromes ou malformações associadas, foram investigadas. Durante exame clínico, a presença de facetas de desgaste e a oclusão dentária foram observadas e foi realizada a palpação na região da articulação temporomandibular (ATM) e musculatura orofacial. As crianças e seus responsáveis foram entrevistados com relação à presença de hábitos orais parafuncionais (bruxismo, ato de morder os lábios e/ou bochechas, onicofagia, sucção de dedos e de chupeta) e sinais e sintomas de disfunção craniomandibular (cefaléia, ouvido, dor, cansaço ou estalo na ATM durante movimentos de abertura bucal e de mastigação). Os dados foram analisados por meio de medidas de frequência absoluta e relativa e a análise bivariada foi realizada por meio dos testes do Qui-quadrado de Pearson (χ2) e a Razão de verossimilhança, considerando o nível de significância de 5%. Uma maior prevalência das fissuras envolvendo lábio e palato (76,0%) e presença de maloclusão (61,7%) foi observada, com destaque para mordida cruzada anterior (58,7%) e desvio de linha média (48,9%). Houve uma maior ocorrência do ato de ranger os dentes (40,4%), da onicofagia (28,7%) e do hábito de morder lábios e/ou bochechas (28,7%). A onicofagia foi associada à cefaléia (p<0,05) e à dor ou estalo durante abertura bucal (p<0,05). Conclui-se que hábitos orais parafuncionais podem estar associados a presença de sinais e sintomas da disfunção craniomandibular em crianças com FLP.
