Ectopic mandibular third molar in the ramus region: report of a case and literature review.

Objectives: Ectopic mandibular third molar is a rare condition, and information is limited about its causes and characteristics. This article reports a case of ectopic mandibular third molar and reviews the literature on the clinical signs and symptoms and management of this condition.

Study Design: We report a case of an impacted mandibular third molar dislocated high on the right side of the mandibular ramus.

Cardiovascular influence of dental anxiety during local anesthesia for tooth extraction.

Objective: The present study evaluated whether dental patient anxiety has an effect on the cardiovascular response to the delivery of anesthetic to achieve mandibular anesthesia.

Study Design: One hundred eighty adult patients scheduled to receive routine dental extraction under local anesthesia were enrolled in this prospective study. Anxiety was measured at 15 minutes before local anesthetic delivery using Corah's Dental Anxiety Scale (Corah's DAS).

Evaluation of mandibular block using a standardized method.

The purpose of this prospective randomized study was to investigate the manifestations and efficiency of mandibular block (MB) using a standardized method. In this study, 123 patients requiring MB were randomly assigned to receive MB using a repeated measures design. Mandibular block was administered in each patient by using 2.

Comparison of the Gow-Gates mandibular block and inferior alveolar nerve block using a standardized protocol.

Background: Although several previous studies have compared the efficacy of Gow-Gates mandibular block (GGMB) and inferior alveolar nerve block (IANB), the results remain controversial. This study used an objective, standardized and precise protocol to evaluate and compare the effectiveness and success rate of GGMB and IANB.

Methods: The study group consisted of 162 patients (93 males and 69 females) who were randomly allocated to receive GGMB or IANB for extraction of third molars.

Effectiveness of an educational program in reducing the incidence of wrong-site tooth extraction.

Objectives: The aim of the study was to investigate the effectiveness of an educational program on the reduction of the incidence of wrong-site tooth extraction at the outpatient department of a university hospital in Taiwan.

Study Design: Data collected from cases of wrong-site tooth extraction during 1996 to 1998 were used to develop a specific educational intervention that was implemented from 1999 to 2001. The annual incidence of erroneous extraction was compared between the preintervention and intervention periods.
