Documentos convencionais e não convencionais em administração, ciências contábeis e economia: estudo sobre sua utilização pelos alunos de graduação

The recommended bibliographical references for the development of scientific research are those published by scientific journals. In spite of this recommendation, the use of non conventional documents by undergraduate students has been increasing. This paper, developed as a survey with 145 students of Administration, Accounting and Economics, characterizes the use these documents and analyzes teaching strategies supported in the use of non conventional documents.

Two-dimensional radiographic and clinical references of the tooth crown for orthodontic mini-implant insertion: A guide-free technique

Objective. This study evaluated the reliability of tooth-crown radiographic references to aid in orthodontic mini-implant insertion and showed an insertion technique based on these references. Study design. The sample consisted of 213 interradicular septa evaluated in 53 bitewing radiographs. The proximal contour of adjacent tooth crowns was used to define septum width and its midpoint was linked to the interdental contact point to determine septum midline (SML). The distances from SML to mesial and distal teeth were measured and compared to evaluate SML centralization degree in 2 different septum heights. Results. The mesial and distal distances were not statistically different in the midpoint of the septum height, but they were different at the apical septum height. Conclusions. The tooth-crown radiographic references determine a high centralization degree of the SML on which an insertion site could be defined. The greater SML centralization degree was observed at the coronal septum area. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:e8-e16)
