Oral Maxillofac Surg

Department of Craniomaxillofacial and Oral Surgery, University Hospital Zurich, Frauenklinikstr. 24, 8091 Zurich, Switzerland.

Published: December 2012

Purpose: Anxiolytic and possible side effects of clonidine 150 μg compared to midazolam 7.5 mg for premedication in surgical wisdom tooth extraction were evaluated.

Methods: In a prospective, randomized, double-blind crossover trial, ten patients undergoing bilateral wisdom tooth surgery received clonidine or midazolam orally 1 h before the treatment. Patients receiving midazolam for the first surgery received clonidine at the second surgery and vice versa. The anxiolytic efficacy was evaluated with a visual analogue scale (VAS) upon admission and 30, 50 and 60 min after administration of the medication. Patient satisfaction was recorded on a VAS after surgery and 7 days postoperatively.

Results: As soon as 30 min after administration of midazolam (p < 0.03) and clonidine (p < 0.02), an anxiolytic effect was recorded. Both medications did not differ in patient satisfaction.

Conclusion: Oral administration of clonidine 150 μg and midazolam 7.5 mg were rated as medications with equal anxiolytic effects before wisdom tooth surgery under local anesthesia.

Department of Oral and Maxillofacial Surgery, Nara Medical University, 840, Shijo-Cho, 634-8522, Kashihara, Nara, Japan.

Purpose: This study aimed to analyze changes in anxiety and comfort levels at each perioperative stage during third molar extraction under single-agent intravenous midazolam sedation, and to clarify how these conditions at each perioperative stage affect postoperative satisfaction.

Patients And Method: 115 who requested extraction of 1 ~ 4 third molars under single-agent intravenous midazolam sedation were targeted. These patients were administered a questionnaire survey one week after surgery.

Professor, Department of Oral, Dental and Maxillofacial Radiology, Faculty of Dentistry, Ataturk University, Erzurum, 25240, Turkiye.

Objectives: This study aimed to evaluate with ultrasonography (US) the location of GPF, the course of the GPA, and to measure palatal fibromucosa thickness.

Materials And Methods: This in vivo experiment was conducted on a group of healthy, young Turkish subjects. Using the US, the localization of the GPF, its diameter and opening type, maximum flow velocity (Vmax) and collateral branches (CB) of the GPA, and the thickness of the palatine mucosa were evaluated.

Inositol 1,4,5-trisphosphate receptors (IP3R) mediate Ca2+ release from intracellular stores, contributing to complex regulation of numerous physiological responses. The involvement of the three IP3R genes (ITPR1, ITPR2 and ITPR3) in inherited human diseases has started to shed light on the essential roles of each receptor in different human tissues and cell types. Variants in the ITPR3 gene, which encodes IP3R3, have recently been found to cause demyelinating sensorimotor Charcot-Marie-Tooth neuropathy type 1J (CMT1J).
