Morphological analysis and immunohistochemical expression in restorations with self-adhesive resin: A randomized split-mouth design-controlled study.

BACKGROUND: To evaluate the morphology and immunohistochemical expression of MMP-9, TIMP-3, COL-I, TNF-alfa and COX-2 in the dentinopulp complex of restorations with self adhesive composite (Vertise Flow/Kerr) compared with conventional resin composite with self-etching adhesive (Filtek Z250/3M ESPE and Clearfil SE Bond/Kuraray-Noritake). MATERIAL AND METHODS: A randomized, controlled, double-blind, split-mouth, two-arm clinical trial was conducted. Twenty-seven volunteers with third molars indicated for extraction received two deep class I restorations, one with each material. The morphology and immunohistochemical expression were measured at 15 days after the restorative procesures. The data were submitted to the Fisher`s Exct test (α=0.05). RESULTS: Through morphological analysis, a slight disorganization of the odontoblastic layer was visualized, along with a slight inflammatory infiltrate in the VERT and CSEB groups (p< 0.05). In immunohistochemical analysis, TNF-alpha, MMP-9, TIMP-3 and COX-2 demonstrated more cases of positive pulp labeling. CONCLUSIONS: Self-adhesive resin composite and conventional resin composite with a self-etching bonding agent promoted slight alterations in the dentin-pulp complex, indicating a repair ability and reversibility of the inflammatory process against aggressions of the adhesive restorative procedure. Key words:Immunohistochemistry, inflammation, randomized clinical trial, self-adhering composite, dentistry.

Objetivo: Avaliar o conhecimento e o uso dos procedimentos que envolvem a biossegurança por cirurgiões dentistas e assistentes de saúde bucal em um município do sertão de pernambucano, buscando averiguar a compreensão da necessidade e da importância da utilização da biossegurança. Métodos: Estudo observacional descritivo realizado através de questionário aplicado para os profissionais da área odontológica vinculados ao Sistema Único de Saúde (SUS) do município de Arcoverde, Pernambuco, Brasil. A amostra foi constituída de 29 profissionais da área odontológica que responderam ao questionário, sendo 9 dentistas e 20 auxiliares. Resultados: Cem por cento dos profissionais afirmam lavar as mãos antes e depois dos procedimentos. Apenas 20% dos ASB lavam o instrumental em pia fora do consultório; 90% costumam fazer a assepsia da cadeira odontológica após cada atendimento; 95% costumam fazer a assepsia da cuspideira e do equipo/cárter após cada atendimento. Conclusão: Os profissionais possuem conhecimento satisfatório acerca da biossegurança no consultório odontológico. Contudo, deve-se uma atenção especial ao uso de luvas estéreis e de campo cirúrgico durante os procedimentos necessários, bem como à disponibilização de equipamentos de proteção individual aos pacientes, a fim de minimizar o risco de contaminação cruzada.

Aim: To assess the knowledge and use of procedures that involve biosafety by dental surgeons and oral health assistants in a municipality in the backlands of the state of Pernambuco, Brazil, seeking to ascertain the understanding of the need and importance of using biosafety. Methods: This work was a descriptive observational study conducted through a questionnaire applied to dental professionals linked to the Unified Health System (SUS) in the municipality of Arcoverde, Pernambuco, Brazil. The sample consisted of 29 dental professionals who answered the questionnaire, including 9 dentists and 20 assistants. Results: One hundred percent of the professionals say they wash their hands before and after the procedures. Only 20% of ASBs wash the instruments in a sink outside the office; 90% usually perform asepsis of the dental chair after each visit; 95% usually clean the spit and the equipment / sump after each visit. Conclusion: The professionals have satisfactory knowledge about biosafety in the dental office. However, special attention should be paid to the use of sterile gloves and the surgical field during the necessary procedures, as well as the provision of personal protective equipment for patients to minimize the risk of cross contamination.

Perfil dos Pacientes Atendidos no Curso de Odontologia do Sertão de Pernambuco: Perfil dos Pacientes Atendidos no Sertão / Profile of Patients Attended at a Dental School in the Sertão of Pernambuco: Profile of Patients Attended in the Sertão

Introdução: Descrever o levantamento epidemiológico que traça o perfil dos pacientes adultos atendidos na clínica do curso de Odontologia, campus Arcoverde, da Universidade de Pernambuco. Metodologia: Estudo transversal em que foi realizada uma análise retrospectiva de 275 prontuários correspondentes aos anos de 2015 a 2017. Foram descritos: dados demográficos; queixa principal; hábito (tabagismo); presença de variação da normalidade e lesões em cavidade oral; necessidade de tratamento por especialidade e número de tratamentos concluídos. Os dados foram tabulados, e a análise estatística foi realizada no programa Statistical Package for the Social Sciences. Resultados: O gênero feminino foi o que mais procurou atendimento (64,7%), e a 3ª década de vida foi a mais atendida. As especialidades com maior necessidade pelos pacientes foram a Dentística e a Periodontia, e o hábito de fumar de alguns pacientes esteve relacionado com uma maior necessidade de tratamento periodontal. Além disso, os homens apresentaram maior necessidade desse tipo de tratamento que as mulheres. A variação da normalidade mais prevalente foi a linha alba (25,5%). As lesões mais comuns diagnosticadas clinicamente foram a leucoplasia (15%) e a queilite actínica (15%), e os homens apresentaram maior frequência da presença de lesões que as mulheres, assim como as pessoas que eram tabagistas e que trabalhavam expostas ao sol. Conclusões: A definição do perfil epidemiológico dos pacientes atendidos poderá auxiliar no planejamento de ações e qualificação da assistência... (AU)

Introduction: To describe the epidemiological profile of adult patients attended at the dental school of the Arcoverde campus, University of Pernambuco. Methodology: In this cross-sectional study, 275 medical records from the period from 2015 to 2017 were analyzed retrospectively. They included the following information: demographic data, main complaint, habit (smoking), presence of alterations and lesions in the oral cavity, need for specialty treatment, and number of treatments completed. The data were tabulated and the Statistical Package for the Social Sciences was used for statistical analysis. Results: Women most frequently sought care (64.7%) and the third decade of life was the most attended. The specialties most needed by the patients were Dentistry and Periodontics, and the smoking habits of some patients were related to a greater need for periodontal treatment. In addition, men presented a greater need for this type of treatment than women. The most prevalent alteration was linea alba buccalis (25.5%). The most common clinically diagnosed lesions were leukoplakia (15%) and actinic cheilitis (15%), and men were more frequent in presenting with lesions than women, as were people who smoked and worked in the sun.

Efficacy of Nd:YAG and GaAlAs lasers in comparison to 2% fluoride gel for the treatment of dentinal hypersensitivity.

Lasers demonstrate excellent therapeutic action and are often employed in dentistry for the treatment of diverse clinical conditions. The aim of this study was to compare the efficacy of neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser, gallium-aluminum-arsenide (GaAlAs) laser, and 2% neutral fluoride gel in the treatment of dentinal hypersensitivity. Twenty-three patients were evaluated, involving a total of 48 quadrants with at least 1 tooth with dentinal hypersensitivity (89 teeth total). Pain intensity was recorded on a visual analog scale at the time of clinical examination (baseline), immediately after treatment, and 1 week posttreatment. Teeth were treated with 60 seconds of 2% neutral fluoride gel application or 60 seconds of laser treatment-Nd:YAG laser at a distance of 0.5 cm (unfocused; 1 W and 10 Hz for 60 seconds, perpendicular to the cervical surfaces) or GaAlAs laser in contact (40 mW; 4 J/cm²; spot: 0.028 cm²; 15 seconds per point on 4 points [mesial, medial, distal, and apical])-as well as sham treatments so that patients remained blind to their treatment group. All treatments provided adequate pain reduction immediately posttreatment, but laser treatments resulted in significantly greater reductions in pain intensity.
