Do ultrasonic dental scalers interfere with implantable cardioverter defibrillators? An in vivo investigation.

Objectives: To test the in vivo effects of an ultrasonic dental scaler on various implanted cardioverter defibrillator (ICD) models.

Methods: 12 consecutive patients with ICDs had continuous both electrocardiogram monitoring and device interrogation to detect interferences during the use of an ultrasonic dental scaler.

Results: No interferences were detected by any ICD.

Effect of submucosal injection of dexamethasone on postoperative discomfort after third molar surgery: a prospective study.

Purpose: The purpose of this study was to evaluate the effect of submucosal administration of dexamethasone sodium phosphate on discomfort after mandibular third molar surgery.

Patients And Methods: Sixty-one consecutive patients requiring surgical removal of a single mandibular impacted third molar under local anesthesia were randomly placed into 3 groups. After the onset of local anesthesia, the experimental groups received dexamethasone at 2 different doses (4 or 8 mg) as submucosal injection, and the control group received no drug.

Assessing postoperative discomfort after third molar surgery: a prospective study.

Purpose: The purpose of this study was to identify the risk factors for severe discomfort after mandibular third molar surgery and to assess the validity of the Postoperative Symptom Severity (PoSSe) scale.

Patients And Methods: In a 2-year prospective study, a total of 255 unilateral impacted mandibular third molar teeth were surgically removed under local anesthesia by 3 surgeons. Standardized surgical and analgesic protocols were followed.
