Dental care for patients with special needs at a private higher education institute / Atendimento odontológico a pacientes com necessidades especiais em uma instituição privada de ensino superior

Objetivo: Pacientes com necessidades especiais são aqueles indivíduos que necessitam de cuidados especiais por tempo indeterminado ou por toda a vida. O presente estudo tem como objetivo abordar o atendimento odontológico de pacientes com necessidades especiais em uma instituição privada de ensino superior da cidade de São Paulo. Material e Métodos: Foi realizado um estudo descritivo, retrospectivo, para análise de 210 prontuários odontológicos de pacientes com necessidades especiais atendidos no Departamento de Odontologia para Pacientes Especiais da Universidade Cruzeiro do Sul entre 2012 e 2018. Dados sobre sexo, idade, diagnóstico da condição debilitante, motivo da consulta, uso continuado de medicamentos, imagens radiográficas e tratamentos odontológicos prestados foram todos coletados e posteriormente submetidos à análise estatística descritiva e inferencial (teste do qui-quadrado) ao nível de significância de 5%. Resultados: Quanto aos tipos de procedimentos odontológicos avaliados no presente estudo, dos 210 pacientes, 24% necessitaram de tratamentos curativos dentários em que a terapia periodontal foi o tipo mais prevalente, enquanto os tratamentos endodônticos tiveram a menor prevalência, representando apenas 4%. Houve alta prevalência de doenças crônicas sistêmicas, acometendo 56% dos casos, cuja faixa etária era superior a 40 anos. Conclusão: Check-ups odontológicos regulares devem ser priorizados em pacientes com necessidades especiais para evitar intervenções mais invasivas como em nosso grupo (AU)

Objective: Patients with special needs are those individuals who need special care for an undetermined period of time or for lifetime. The present study is aimed to address the dental care of special needs patients at a private higher education institute in the city of São Paulo. Material and Methods: A descriptive, retrospective study was performed for analysis of 210 dental records of special needs patients who were treated at the Dental Department for Special Patients of the Cruzeiro do Sul University between 2012 and 2018. Data on gender, age, diagnosis of the debilitating condition, reason of the consultation, continued use of medications, radiographic images and dental treatments provided were all collected before being submitted to descriptive and inferential statistical analysis (chi-square test) at a significance level of 5%. Results: As for the types of dental procedures assessed in the present study, of the 210 patients, 24% needed dental curative treatments in which periodontal therapy was the most prevalent type, whereas endodontic treatments had the lowest prevalence, representing 4% only. There was a high prevalence of chronic systemic diseases, affecting 56% of the dental records, whose age group was above 40 years old. Conclusion: Regular dental check-ups should be prioritized in patients with special needs to avoid more invasive interventions as found in our group (AU)

In Vitro Quantitative Evaluation of Postprocessing Filter for Metal Artifact Reduction in Cone Beam Computed Tomography Images of Titanium and Zirconium Dioxide Implants.

Objective: To evaluate a postprocessing filter of a new imaging-processing software for analysis of metal artifact reduction. Methods: Eight artificial edentulous mandibles (phantoms), where titanium and zirconium dioxide implants had been installed in four different regions (i.e., incisors, canine, premolars, and molars). CBCT volume was acquired, and then, four types of filters were applied to the images: BAR filter and Multi-CDT NR filter (e-Vol DX) and Sharpening Filters 1x and 2x (OnDemand). Artifact was assessed by measuring the standard deviation (SD) of the gray values of filtered and unfiltered images. The comparison between implant material, teeth, and filters was performed by using ANOVA, whereas multiple comparisons were performed by using Bonferroni's test. The level of significance adopted was 5%. Results: The results showing higher SD values, which suggests a worse image, were obtained with titanium implants compared to zirconium dioxide ones. With regard to the four filters used, it can be seen that the lowest SD values were obtained with BAR and Multi-CDT NR filters and the highest with Sharpening Filters 1x and 2x, with no statistical difference between them, except regarding the molar region in titanium implants. Conclusion: The highest SD values were seen in zirconium dioxide implants, mainly in the region of anterior teeth. The BAR filter was found to be the most effective as its SD value decreased significantly, indicating that the image quality was improved.
