ABSTRACT

Abstract The aim of this study was to evaluate the influence of drying protocols (DP) on the apical sealing (AS) and on the bond strength (BS) of teeth filled with different sealers. The root canals of one hundred and fifty-six roots of maxillary canines were prepared with Reciproc rotary files (R50). The teeth were randomly divided into four groups (n = 39), according to the DP: GI-paper points; GII-70% isopropyl alcohol + aspiration with NaviTip points; GIII-95% ethanol + paper points; GIV-EndoVac + paper points. Each group was divided into subgroups, according to the sealer used: AH Plus, Sealapex and MTA Fillapex, using a single-cone technique. Evaluation of AS and BS was performed with fluid filtration (FF) and push-out (PO) methods, respectively. The PO test consisted of sectioning the roots, and subjecting a single slice from each third to testing and analysis for failure type. The data was submitted to two-way and three-way variance analysis (ANOVA) and Tukey (α = 5%). The AS showed no drying protocol influence. The FF results revealed a statistically significant difference between MTA and Sealapex (p < 0.05) sealers. The BS test values showed that there was no statistical significant difference among the canal thirds (p > 0.05), but that there was such a difference among the sealers (p < 0.05), among the protocols (p < 0.05), and in the interaction between sealers and protocols (p < 0.05). AH Plus revealed the highest BS values among the sealers; the highest BS results for the sealers occurred with the specimens used with isopropyl alcohol, compared with ethanol and EndoVac.

ABSTRACT

O padrão estético de beleza do corpo imposto pela sociedade contemporânea tem sido o responsável pelo aumento do número de casos de bulimia nervosa. Essa doença comportamental que leva a transtornos alimentares acarreta danos fisiológicos que, se não erradicados precocemente, podem se tornar irreparáveis. Dentre esses danos, destacam-se àqueles relacionados à saúde bucal, caracterizados pela perimólise, aumento nos índices de lesões cariosas, intumescimento das glândulas salivares, sobretudo as parótidas, alterações na quantidade e qualidade da saliva, xerostomia, queilite e mucosite, bruxismo e alterações ortodônticas. As manifestações bucais são causadas por higiene bucal insatisfatória, deficiências de vitaminas, pela ingestão crônica de carboidratos, pela compulsão alimentar, pouca salivação (xerostomia), ansiedade e, também, pela acidificação da saliva causada pelos vômitos. O cirurgião-dentista, a partir do conhecimento dos sinais e sintomas dessa doença, é potencialmente um dos primeiros profissionais de saúde a identificá-la, podendo oferecer tratamento odontológico adequado.


The aesthetic beauty standard imposed by contemporary society has been responsible for the increasing bulimia rates. This behavioral disease that leads to eating disorders results in physiological damages that can become permanent if not treated early. These damages may affect oral health and include perimolysis, more caries lesions, swelling of the salivary glands, especially the parotid glands, changes in the amount and quality of the saliva, xerostomia, cheilitis and mucositis, bruxism and orthodontic changes. The oral manifestations are caused by poor oral hygiene, vitamin deficiencies, chronic carbohydrate intake, binge eating, xerostomia, anxiety, and also because of the acidification of the saliva due to vomiting. Based on the signs and symptoms of this disease, the dental surgeon is potentially one of the first health professionals to identify it and can provide proper dental treatment.

ABSTRACT

Esse estudo avaliou a percepção dos usuários quanto à saúde bucal e ao serviço público odontológico no município de Montes Claros/MG. Os participantes foram selecionados de uma lista dos usuários adultos agendados para tratamento odontológico no Programa de Saúde da Família (PSF). Após assinatura do termo de consentimento, os usuários foram entrevistados, sendo suas falas gravadas, transcritas e submetidas à análise de conteúdo. Os usuários relacionaram saúde bucal com saúde sistêmica, cuidados com a boca e aparência. Muitos desconheceram o significado de PSF, bem como sua lógica de funcionamento. Para os usuários, o PSF favoreceu a proximidade com o profissional de saúde, contribuindo para o acolhimento satisfatório. Houve reflexões sobre universalidade. Os agentes comunitários e as reuniões coletivas foram considerados facilitadores do acesso ao serviço odontológico. No discurso sobre os fatores limitantes do acesso houve referência do grande número de usuários e do tempo de espera para atendimento odontológico.
