Hemodynamic changes comparing 2% lidocaine and 4% articaine with epinephrine 1: 100,000 in lower third molar surgery.

Background: An increase in blood pressure during dental treatment has been investigated with regard to potential medical risks since previous studies suggest that dental procedures may cause stress to the patient and, consequently, the cardiovascular system. The aim of the present study was to analyze hemodynamic changes following the administration of either 2% lidocaine (L100) or 4% articaine (A100) (both with epinephrine 1:100,000) in the surgical removal of symmetrically positioned lower third molars.

Methods: A prospective, randomized, double-blind, clinical trial was carried out involving 47 patients.

Bone morphogenetic protein-2/4 and bone morphogenetic protein receptor type IA expression in metastatic and nonmetastatic oral squamous cell carcinoma.

Purpose: The study aimed to analyze the expression of bone morphogenetic protein-2/4 (BMP-2/4) and its receptor BMPR-IA (BMP receptor type IA) in metastatic and nonmetastatic oral squamous cell carcinoma (OSCC) and its implications for disease prognosis.

Materials And Methods: The experimental group included 16 cases of OSCC without metastasis and 7 cases of OSCC with metastasis. The presence or absence of nodal metastasis was used as a parameter for the evaluation of disease prognosis.

Passive drainage through the vestibular oblique incision in impacted inferior third molar surgery: a preliminary study.

The aim of the present study was to clinically evaluate the variables pain, swelling and trismus when two different suture techniques were applied in surgery of impacted lower third molars. The sample comprised 20 patients of both genders participating in the clinical trial at the Division of Oral and Maxillofacial Surgery, with an indication for the removal of bilaterally impacted lower third molars. They were divided into test and control groups.

Glove perforation during oral surgical procedures.

Objective: The aim of this study was to determine the incidence of glove perforation among undergraduates and residents performing maxillofacial surgery and identify procedures associated with the perforations.

Study Design: For this purpose, 200 pairs of surgical gloves were used. For inspecting the perforations, the gloves were filled with water, at least 500 ml.
