ABSTRACT
Se presenta un Caso Clínico de una paciente de género femenino, 90 años 6 meses de edad, con diagnóstico inicial de Coxartrosis Bilateral de Cadera. Se le realizó Reemplazo Total de Cadera hace 30 años del lado izquierdo (1990) con una Prótesis de Roy Camille, y hace 25 años se intervino el lado derecho (1997) con una Prótesis Bipolar Cementada. En el año 2019 se llevó a Revisión de Prótesis de Cadera.
We present a Clinical Case of a female patient, 90 years 6 months of age, with an initial diagnosis of Bilateral Hip Coxarthrosis. Total Hip Replacement was performed 30 years ago on the left side (1990) with Roy Camille Prosthesis, and 25 years ago the right side (1997) was intervened with a Cemented Bipolar Prosthesis. In the year 2019 he took o hip Prosthesis Review.

Aim:To evaluate the preferences of the dentists' attire among parents.Study Design: Descriptive cross-sectional study.Methodology:A questionnaire was used to obtain socio-demographic information and their preferences from Parents that accompanied their children to the Paediatric dental clinic. Information was also elicited from photographs showing male and female dentists’ with different attires and protective wears. The data was analyzed using SPSS version 22 and the level of significance was set at <0.05.Results: One hundred and fifty parents, comprising of 105(70%) females and 45(30%) males were assessed. The 40-49 year age-group were the majority [73(48.7%)], the female dentist was the preferred gender and there were statistically significant differences between the male and female subjects (p=0.047). One hundred and forty-six (97.3%) wanted the dentists to wear name tags mostly for ease of identification 103(68.8%) and communication 20(13.3%). All parents wanted the dentist to don protective coat and gloves, while 123(82%) and 80(53.3%) parents preferred dentists' wearing facemasks and protective glasses, respectively. One hundred and twenty-eight (85.3%) preferred the white coats because it depicts purity/cleanliness (51.4%) and professionalism (45.7%).Dentists attire was important to 82% and there were statistical significant differences (p=0.01) between those with previous dental exposure and first-timers. There were statistically significant differences (p=0.03) between procedures [orthodontics and other procedures] done in the present visit and their perception of dentist attire.Conclusion:The preferences of the parents on protective wears, use of name tags and gender of the dentist show that identification, safety, empathy and rapport were desiredfrom the dentist by the parents. Previous exposure of their children to the dental setting had an influence on the parents’ preferences
ABSTRACT
Proposição: O objetivo deste trabalho, dividido em três estudos, foi investigar o efeito após a aplicação de ondas de ultrassom sobre cimentos de ionômero de vidro (CIV) (1) a dureza da dentina subjacente, hígida e afetada por cárie; (2) a resistência de união à dentina hígida e afetada por cárie (3) e à rugosidade do material após ensaio de escovação. Materiais e métodos: Nos três estudos foram utilizados os CIV Vitremer (VT) e Ketac Molar Easymix (KM). Para o estudo 1 foram realizados preparos cavitários (3 mm de largura, 5 mm de comprimento e 2 mm de profundidade) na face vestibular de 80 incisivos bovinos. Foi realizada a indução de lesão de cárie artificial pelo método microbiológico (n=40). Os dentes foram distribuídos em 8 grupos (n=10), segundo o substrato (hígido ou afetado por cárie), material utilizado (VT ou KM) e o tratamento recebido (com ou sem a aplicação de ondas de ultrassom). A aplicação de ondas de ultrassom foi realizada por 30 segundos. Após 30 dias de armazenagem em água os dentes foram seccionados e as leituras de dureza Knoop realizadas na dentina subjacente ao material até 200 μm de distância da interface dentina/CIV. No segundo estudo foram confeccionados 20 blocos de dentina bovina para cada material, sendo que 10 deles foram submetidos ao processo de indução de lesão de cárie artificial e subsequente remoção da dentina contaminada. Em cada bloco foram confeccionados dois corpos de prova com 1,5 cm de altura e 3 cm de diâmetro, sendo o primeiro com e o segundo sem a aplicação de 30 segundos de ondas de ultrassom. Após 24 horas, os corpos de prova foram submetidos ao ensaio mecânico de cisalhamento. No terceiro trabalho 32 espécimes de cada material, VT e KM, foram confeccionados em matriz de dente bovino, sendo que a metade recebeu ondas...
Aim: This work was divided into three studies. The objective was to investigate the effect of ultrasound application on glass ionomer cement (GIC), analyzing underlying dentin hardness, bond strength to noncarious dentin and cariesaffected dentin and the material roughness after toothbrushing test. Materials and methods: GIC Vitremer (VT) and Easymix Ketac Molar (KM) were used in these studies. In the first study, cavities (3 mm wide, 5 mm in length and 2 mm deep) were performed on the buccal surface of eighty bovine incisors. Microbiological method was used to induce artificial caries lesions (n = 40). The teeth were divided into 8 groups (n = 10), according the substrate (noncarious dentin or caries-affected dentin), the material used (VT or KM) and the treatment received (with or without ultrasound application). The ultrasound application was performed for 30 seconds, and teeth stored in water for 30 days. After that, the specimens were sectioned and transversal hardness evaluation was performed in the underlying dentin material up to depth of 200 μm. In the second study, 20 dentin blocks were used for each material. Ten of them were artificially decayed and performed subsequent removal of infected dentin. In each block, two specimens (1.5 cm high and 3 cm diameter) were performed, the first with and the second without ultrasound application. After 24 hours the specimens were shear bonding tested. For the third study 32 specimens of each material, VT and KM, were prepared using a bovine tooth matrix. Half of them received a 30 s ultrasound application during its initial setting. The surface roughness, before and after toothbrushing test, was evaluated at 24 hours (n = 16) and 30 days (n = 16). Data were analyzed by ANOVA and Tukey tests. For all the studies, the statistical tests were considered at the present level...

PURPOSE: To evaluate etiology, risk factors and clinical features in eyes with sports-related injuries. METHOD: A prospective evaluation of all patients presenting with a sports-related ocular injury was conducted at Dongguk University Pohang Hospital from January 1999 to December 1999. RESULT: There were 29 patients, representing 8.0% of all ocular trauma patients. Male was injured more often than female by a ratio of 6.25:1, and the mean age was 25.8+/-14.3 years. Soccer accounted for 37.9% and basketball accounted for 13.8% of all injuries. The mechanism most frequently responsible for injuries was direct ball trauma(51.7%). Six patients(20.7%) wore spectacles, whereas none of patients wore protective eye wear, at the time of their injury. Lid subcutaneous hemorrhage or edema(12 eyes) was the most common injury, and corneal abrasion(11 eyes) and retinal edema(7 eyes) occurred frequently. Traumatic hyphema and traumatic iritis occurred in 5 eyes, respectively. CONCLUSION: Sports-related ocular trauma is one of the significant causes of ocular morbidity. Even though all sports-related ocular trauma is not preventable, increased education such as use of certified protective eye wear is needed if the frequency or severity of injuries is to be decreased.
