Rastreabilidade dos usuários atendidos no Núcleo de Acolhimento e Pronto Atendimento de uma clínica-escola de Odontologia / Trazabilidad de los usuarios atendidos en el Centro de Acogida y Urgencias de una clínica-escuela de odontología / Traceability of users attended at the Reception and Emergency Care Center of a dental clinic-school

A pesquisa teve como objetivo verificar a rastreabilidade dos pacientes atendidos no setor de urgência do Núcleo de Acolhimento e Pronto Atendimento da Universidade Federal de Pernambuco (NAPA-UFPE), o tempo decorrido entre seu encaminhamento e a continuidade do tratamento na instituição, além de identificar o perfil dos usuários. Trata-se de estudo observacional descritivo, com coleta de dados a partir dos prontuários físicos e eletrônicos dos pacientes atendidos no segundo semestre de 2014 (2014.2) e no primeiro semestre de 2015 (2015.1). Ao total, foram analisados 373 prontuários. Em ambos os semestres houve maior prevalência do sexo feminino e da faixa etária entre 20 e 59 anos. A rastreabilidade revelou que 40,75% dos pacientes continuaram seus tratamentos na instituição. Nos semestres 2014.2 e2015.1, respectivamente, 31,20% e 82,00% dos pacientes prosseguiram com o tratamento eletivo até 30 dias após a realização do atendimento de urgência. Em conclusão, a rastreabilidade revelou maior prevalência do sexo feminino e da faixa etária adulta. O quantitativo de pacientes que deram continuidade ao tratamento na instituição em até 30 dias após o encaminhamento esteve dentro do previsto, considerando-se as características das clínicas-escola (AU).

El objetivo de la investigación fue verificar la trazabilidad de los pacientes atendidos en el sector de urgencias del Centro de Recepción y Atención de Urgencias de la Universidade Federal de Pernambuco (NAPA-UFPE), el tiempo transcurrido entre su derivación y la continuidad del tratamiento en la institución, además de identificar el perfil de los usuarios. Se trata de un estudio observacional descriptivo, con recolección de datos de los registros físicos y electrónicos de pacientes atendidos en el segundo semestre de 2014 (2014.2) y en el primer semestre de 2015 (2015.1). En total se analizaron 373historias clínicas. En ambos semestres hubo mayor prevalencia del sexo femenino y del grupo de edad entre 20 y 59 años. La trazabilidad reveló que el 40,75% de los pacientes continuaron sus tratamientos en la institución. En los semestres 2014.2 y 2015.1,respectivamente, el 31,20% y el 82,00% de los pacientes continuaron con el tratamiento electivo hasta 30 días después de la atención de emergencia. En conclusión, la trazabilidad reveló una mayor prevalencia del sexo femenino y del grupo etario adulto. Elnúmero de pacientes que continuaron el tratamiento en la institución dentro de los 30 días posteriores a la derivación estuvo dentro del rango esperado, considerando las características de las clínicas docentes (AU).

The objective of this study was to verify the traceability of patients attended in the emergency sector of the Reception and Emergency Care Center of the Federal University of Pernambuco (NAPA-UFPE), the time elapsed between their referral and the continuity of treatment at the institution, in addition to identifying the users' profile. This is a descriptive observational study, with data collection from the physical and electronic medical records of patients treated in the second half of 2014 (2014.2) and in the first half of 2015 (2015.1). A total of 373 medical records were analyzed There was a higher prevalence of females and an age group between 20 and 59 years in both semesters. The traceability revealed that 40.75% of the patients continued their treatments at the institution. Moreover, 31.20% and 82.00% of the patients in the 2014.2 and 2015.1 semesters continued with the elective treatment up to 30 days after the emergency care, respectively. In conclusion, traceability revealed a higher prevalence of females and the adult age group. The number of patients who continued treatment at the institution within 30 days after referral was within the expected range, considering the characteristics of the teaching clinics (AU).

SEGUNDOS MOLARES DECÍDUOS: REABSORÇÃO FISIOLÓGICA E PATOLÓGICA / Second deciduous molars: physiological and pathological resorption

Objetivo: Este estudo retrospectivo avaliou a perda dos segundos molares decíduos, por rizólise fisiológica ou patológica, em pacientes atendidos nas Clínicas de Odontopediatria I e II da Universidade Federal de Pernambuco. Foram examinados 112 prontuários, sendo os dados registrados em fichas individuais. Método: Foram analisadas as seguintes variáveis: gênero, faixa etária, tipo de tratamento (invasivo ou não invasivo), tipo de reabsorção dentária (patológica ou fisiológica) e arco dentário. Resultados: A reabsorção fisiológica foi mais frequente que a reabsorção patológica em ambos os arcos. Foi observado que existe associação estatisticamente significante entre a faixa etária de 2 a 4 anos e a reabsorção dentária (p<0,001). A média de idade dos pacientes para reabsorção fisiológica foi de 6,65 e 4,49 anos para a reabsorção patológica dos segundos molares decíduos. Conclusão: Houve perda precoce de segundos molares decíduos. Há grandes possibilidades de comprometimento da oclusão funcional do indivíduo.

Aim: This retrospective study evaluated the loss of the second deciduous molars either by physiological or pathological root resorption in patients enrolled at the Pediatric Dentistry Clinic I and II at the Federal University of Pernambuco. Methods: A review of 112 patient records were assessed and registered in a form. The following variables were analyzed: gender, age, type of treatment (invasive or no invasive), type of resorption (physiological or pathological) and region (maxillary or mandibular). Results: The physiological resorption was more observed than the pathological resorption in both arches. It was noted that there was a statistically significant association between the age group of 2-4 years old and the resorption (p<0.001). The mean age of patients for physiological resorption was 6.65 and 4.49 years old for pathological resorption of the second deciduous molars. Conclusion: It can be concluded that there was an early deciduous second molars loss. There are great possibilities of impaired functional occlusion of the individual.

Changes in root canal anatomy using three nickel-titanium rotary system: a cone beam computed tomography analysis

AIM: Cone beam computed tomography (CBCT) was used to evaluate the ability of three NiTi rotary systems to maintain the original root canal anatomy. METHODS: Sixty mesiobuccal canals of human mandibular first molars were divided into three groups with 20 root canals each. All teeth were scanned by CBCT before instrumentation. The images were captured digitally for further analysis using the Image Tools Software. The images were sectioned in three points, located at 9 mm, 6 mm and 3mm from the apex. In Group 1, the root canals were instrumented with ProTaper UniversalTM rotary system; in Group 2, with Twisted FileTM rotary system; and in Group 3, with MtwoTM rotary system. Instrumented teeth were scanned again using CBCT and the images of the uninstrumented canals were compared with images of the instrumented canals. The results were statistically analyzed using the one-way ANOVA test. A level of significance of 0.05 was adopted. RESULTS: The means of D1 at distances of 9 mm, 6 mm, and 3 mm from the apex were, respectively: Group 1: 0.88±0.257, 1.00±0.000, and 1.00±0.000; Group 2: 0.79±0.745, 0.65±0.669, and 0.25±0; Group 3: 0.50±0.745, 0.33±0.472, and 0.03±0.104. The means of D2 at distances of 9 mm, 6mm, and 3mm from the apex were respectively: Group 1: 1.00±0.00, 1.00±0.00, and 1.00±0.00; Group 2: 0.41±0.299, 0.30±0.428, and 0.50±0.707; Group 3: 0.58±0.910, 0.85±1.857, and 0.31±0.643. CONCLUSIONS: The CBCT analysis revealed that the ProTaper UniversalTM produced centered preparations and while the Twisted FileTM and MtwoTM rotary systems produced canal deviation.
