Forty mesiobuccal roots with curvatures of 20°-35° were used. In group A, glide paths were created with PathFile #1, #2, and #3 to the working length; in group B, no glide paths were used. All canals were instrumented up to F4 to the working length. Digital subtraction radiographic images were obtained in buccolingual and mesiodistal directions. Apical transportation associated with F3 or F4 was calculated based on the difference between the tip of the first and the last instrument analyzed in each group. RDT was calculated based on cone-beam computed tomographic images. Apical transportation was higher after F4 regardless of the use of the PathFile system. No statistically significant differences between groups A and B were observed in apical transportation after instrumentation with F3 or F4 (P &amp;amp;amp;amp;amp;amp;amp;gt; .05). Group A showed greater RDT values at 2 (buccal and mesial walls, P &amp;amp;amp;amp;amp;amp;amp;lt; .05) and 3 mm (buccal and distal walls, P &amp;amp;amp;amp;amp;amp;amp;lt; .05) from the apex but not at 1 mm. The use of the PathFile system before root canal preparation with ProTaper Universal F3 and F4 did not influence apical transportation but was associated with greater RDTs at 2 and 3 mm from the apex.

The behavior of the cancer is very aggressive, presenting early cervical metastasis and, often contralateral ranging from 0.9 to 36%. Objectives: This study aims to analyze clinical and pathological factors that may influence metastasis of squamous cell carcinoma in cervical lymph nodes and relate this occurrence in the contralateral primary tumor, with disease prognosis and the interference of this type of metastasis in the survival rate of patients with this pathology. Material and Metohds: It was conducted a retrospective study from medical records of patients with Squamous Cell Carcinomas with homolateral lymph node metastasis and contralateral attended at the clinic of Head and neck surgery of Hospital São Vicente de Paulo in Passo Fundo -RS -Brazil, from 2000 to 2008. Results: Analyzing the charts of patients with metastatic and metastatic contralateral side it was observed that patients with initial stage presented a higher survival with statistical significance (p=0,035). Conclusions: The occurrence of metastases in lymph nodes of contralateral position to the primary lesion was not the main fator that influenced the survival of the group.

Para tanto, foram selecionados 308 pacientes, agendados para o exame de triagem na Faculdade de Odontologia da UPF, que apresentavam boa saúde geral. Os mesmos foram examinados clinicamente, sendo realizada a inspeção e palpação extra e intrabucal, complementadas pela avaliação da radiografia panorâmica. Concluiu-se que a maioria dos pacientes apresentou algum tipo de lesão associada ao uso de próteses dentárias;; o gênero feminino apresentou maior prevalência em relação ao masculino;; e que a má higiene e o uso de próteses antigas são os principais fatores etiológicos para a presença de patologias nas mucosas de suporte protético.
