Abstract
Introduction
A new nickel-titanium (NiTi) rotary file called the ProFile Vortex (PV; Denstply, Tulsa Dental Specialties, Tulsa, OK) has recently been released for endodontic use. The purpose of this study was to compare cyclic fatigue resistance of the new size 30 PV files with size 30 files of other popular brands. Other files tested include Twisted File (TF; Sybron Dental Specialties, Orange, CA), ProFile (PF; Denstply Tulsa Dental Specialties, Tulsa, OK), GTX (GTX, Denstply Tulsa Dental Specialties), and EndoSequence (ES; Brasseler, Savannah, GA).

Methods
Size 30 files with a constant .06-mm/mm taper were rotated at manufacturer-recommended speed and torque settings in a simulated canal until failure.

Results
Significant differences were found between the various brands of files. The differences between file brands may be because of a different manufacturing process or differences in file design.

Conclusions
Based on a simulated canal model, the PV, TF, and GTX files appear to offer greater cyclic fatigue resistance than ES and PF files.

CASO CLÍNICO
Tratamento Endodôntico de Incisivo Lateral Superior Após Falha da Cirurgia Parendodôntica
RESUMO
O propósito deste artigo é relatar um caso clínico no qual foi realizada uma intervenção cirúrgica parendodôntica no incisivo lateral superior esquerdo em um paciente para remoção de uma lesão no periodonto apical, sem um prévio tratamento endodôntico, tendo a incisão, a enucleação da lesão e a sutura sido feitas de maneira equivocada, provocando uma fenestração tecidual no tecido gengival, expondo o tecido ósseo ao meio bucal, com consequente infecção e grande quantidade de exsudato purulento. Foi realizado um tratamento endodôntico no dente em questão, utilizando-se a limpeza e modelagem do canal com instrumentação rotatória e hipoclorito de sódio a 5,25%, cavitação ultrassônica com EDTA a 17%, curativo intracanal com hidróxido de cálcio e, em uma sessão posterior, obturação com guta-percha termo plastificada e cimento resinoso. Durante o exame clínico radiográfico de proservação realizado após quatro meses de concluído o tratamento endodôntico, foi observado a recuperação do tecido gengival e a radiografia periapical mostrou uma regeneração do tecido ósseo, onde antes existia a lesão.
