Clinical and surgical evaluation of the indication of postoperative antibiotic prescription in third molar surgery.

Objective: The aim of this study was to evaluate the need for antibiotic prescription in third molar surgery.

Study Design: A double-blind randomized study was carried out with 71 patients from CODONT (Dentistry Center of the Police of São Paulo). Amoxicillin, clindamycin, or no medication was administered for 7 days immediately after surgery.

Comparison of the fracture torque of different Brazilian mini-implants.

This study evaluated fracture torque by torsion, in relation to the length and diameter of orthodontic mini-implants, to demonstrate their viability for clinical and experimental use based on the torque recommended by the manufacturers. The fractures at the moment of insertion, whose incidence in the literature is around 4%, are principally due to excessive force and the inability of the implant to resist rotational forces. Thirty orthodontic mini-implants of three commercial brands available in Brazil (Neodent 1.

A study of effectiveness of midazolam sedation for prevention of myocardial arrhythmias in endosseous implant placement.

Purpose: The study aimed to assess electrocardiographic alterations during oral implant placement surgeries under local anesthesia (lidocaine chlorhydrate with epinephrine), using 15 mg of midazolam as an anxiolytic premedication.

Material And Methods: The study randomly selected 20 patients, aged 21-50 years old, requiring bilateral mandibular dental implants. Each patient was assessed using placebo on one side and midazolam on the contralateral side, with random, double-blinded distribution.

Electrocardiographic alterations during endosseous implant placement performed with local anesthetic agents.

Purpose: The purpose of this study was to analyze electrocardiographic alterations during dental implant surgeries when local anesthetic agents were used.

Materials And Methods: Twenty implants were placed in 18 healthy patients. An electrocardiogram and Wincardio software were used to gather recordings from 12 static leads every 2 minutes, continuously record coronary artery (D2) derivations, and automatically measure the following electrocardiographic parameters: heart rate, duration and amplitude of the P wave, PR segment duration, ST segment deviation, QRS complex duration, and duration of the RR, QT, and corrected QT (QTc) intervals.
