Purpose: To evaluate the influence of anxiety on blood pressure and heart rate during dental care in patients of the Dentistry Clinic in Rio Preto University Center -UNIRP, São José do Rio Preto, São Paulo, Brazil.Methods: A sample of 60 volunteers who sought for the dental screening service was selected. We used a scale to evaluate the volunteers' anxiety level. Blood pressure and heart rate of patients were also checked in different periods of the dental treatment.Results: Most of the volunteers were women. The relation between anxiety and pain before treatment, revealed that 54 (90.0%) had no pain. The patients had low anxiety towards the use of different anesthetic solutions used during dental procedures. There was no statistically significant difference concerning to systolic blood pressure at first and, after application of anesthetic, given the degree of anxiety. Heart rate does not change as a function of anxiety. There is a slight change in heart rate after anesthesia, and it soon gets back to normal.Conclusion: There was no difference in behavior of systolic and diastolic blood pressure in relation to the anxiety level and pain, measured before, during and after the procedure. Heart rate did not change during dental treatment in the patient anxiety level.Key words: Anxiety; blood pressure; heart rate; dental treatment ResumoObjetivo: Avaliar a influência da ansiedade detectadas por meio de uma escala de ansiedade sobre os níveis de pressão arterial e a frequência cardíaca, durante o atendimento odontológico de pacientes das Clínicas de Odontologia do Centro Universitário de São José do Rio Preto, São Paulo, Brasil.Metodologia: Foram selecionados ao acaso 60 voluntários que receberam atendimento odontológico de urgência. Foi utilizada uma escala para avaliar o grau de ansiedade dos voluntários. Foi verificada também a pressão arterial e a frequência cardíaca dos pacientes em três períodos distintos: pré, trans e pós-anestesia odontológica.Resultados: A ansiedade não foi afetada pelas faixas etárias, apenas pelo gênero. A ansiedade não deve ser uma barreira, entre profissional/paciente e, ainda, a ansiedade apresentada não é um sinal clínico levado em consideração para a aplicação de medidas de controle.Conclusão: Não houve alteração da pressão arterial sistólica, diastólica e da frequência cardíaca em relação ao grau de ansiedade e dor e ao tipo de solução anestésica empregada. Anxiety during dental treatment
SUMMARY:The cyclamate, a sweetner substance derived from N-cyclo-hexyl-sulfamic acid, is largely utilized as a noncaloric artificial edulcorant in foods and beverages as well as in the pharmaceutical industry. The objective of this study was to evaluate karyometric and stereological alterations in the rat fetal pancreas resulting from the intraperitoneal administration of sodium cyclamate. The exocrine pancreas of ten fetuses of rats were evaluated, five treated and five controls chosen at random, in which five rats that received from the 10th to 14th days of pregnancy an intraperitoneal daily injection of sodium cyclamate at 60 mg/Kg of body weight during 5 days. At the 20th day of gestation, the animals were removed and weighed, as were their placentas; the length of the umbilical cords also were measured. After the laboratory processing, semi-seriated 6mm cuts stained with haematoxyline and eosine were performed. In seven karyometric parameters (major, minor, and medium diameters, volume, area, perimeter, and volume-area ratio), the increase was statistically significant in the treated group when compared with control group. Stereological parameters showed in the treated group a significant increase in the cellular volume and a significant reduction in the numerical cellular density. These results showed that the sodium cyclamate in pregnant rats led to retardation of fetal development and hypertrophy in the exocrine pancreas of the rat fetuses.
Myiasis is a parasitic disease caused by developing maggots of fly species, which can infect humans. Patients with special needs, especially those with severe neuropsychomotor limitations, may have oral manifestations of this disease. Here, we present a clinical case in which a disabled person was affected by oral myiasis caused by Cochliomyia hominivorax. Maggots were found in two ulcerated lesions, a 2 cm diameter lesion in the maxilla and a 6 cm diameter lesion in the mandible. Forty-five maggots were removed during inspection, whereas 75 maggots were surgically removed under general anesthesia with nasotracheal intubation. Dipyrone, ivermectin, and clindamycin were prescribed, and the patient remained hospitalized for 3 days. Seven days after surgical intervention, no maggots were observed. Our study emphasizes that dentists must recognize the symptoms and behaviors of parasitic diseases that affect the oral cavity.
O objetivo do estudo foi avaliar a deposição de óxido de alumínio no campo operatório do cirurgião-dentista durante a utilização do sistema de abrasão a ar em consultório odontológico, bem como a efetividade da sucção de alta potência na captação desse pó. Por meio de um dispositivo para a coleta das partículas nos locais correspondentes às posições e distâncias de trabalho do profissional, dentes artificiais foram abrasionados. O sistema de sucção empregado para aspiração das partículas foi o de alta potência com sugador de saliva convencional e sugador com abertura ampliada por funil. A mensuração das partículas foi determinada pela quantidade em massa de óxido de alumínio depositada em placas de Petri. Os resultados obtidos por meio de estatística descritiva gráfica revelaram que a maior quantidade de pó se encontrava a 20 cm do operador e na posição de trabalho 9h, quando foi utilizado o sugador de saliva convencional. Uma vez comprovado que a sucção não é totalmente eficiente na aspiração do pó de óxido de alumínio, reforça-se a importância da proteção individual apropriada para o emprego seguro do sistema de abrasão a ar para pacientes e, principalmente, para os profissionais que trabalham com este tipo de tecnologia.
