A quick guide to positioning the transbuccal set.

Exact positioning of the transbuccal set can be tricky, especially under aggravating circumstances as present scarring or high body mass index. It may result in multiple skin incisions. This article presents a simple and fast guidance technique that can help in the exact positioning of skin incision and transbuccal set.

3-Dimensional imaging for lower third molars: is there an implication for surgical removal?

Purpose: Surgical removal of impacted third molars may be the most frequent procedure in oral surgery. Damage to the inferior alveolar nerve (IAN) is a typical complication of the procedure, with incidence rates reported at 1% to 22%. The aim of this study was to identify factors that lead to a higher risk of IAN impairment after surgery.

Anatomy of impacted lower third molars evaluated by computerized tomography: is there an indication for 3-dimensional imaging?

Objective: Surgical removal of impacted third molar is one of the most frequent procedures in oral surgery. Today 3-dimensional (3D) imaging is occasionally used. The aim of this study was to describe and estimate the frequencies of anatomic variations of lower third molars in patients with panoramic findings at high risk for inferior alveolar nerve (IAN) injury.

First clinical application of a liquid-core light guide connected to an Er:YAG laser for oral treatment of leukoplakia.

For medical applications, erbium lasers are usually equipped with articulated mirror arms or special glass fibers. However, only with mirror arms is it so far possible to transmit high average powers or pulse energies in the region of 1 J to achieve suitable energy densities for fast tissue preparation. An alternative to the glass fiber systems mentioned above are liquid-core light guides.

In-line (18)F-fluorodeoxyglucose positron emission tomography with computed tomography (PET/CT) in patients with carcinoma of the sinus/nasal area and orbit.

Background: Contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) are the standard imaging techniques to evaluate patients with carcinoma in the sinus/nasal area and orbit. The use of positron emission tomography (PET) with (18)F-fluorodeoxyglucose (FDG) in such patients is as yet less well established.

Purpose: The aim of this study was to assess the clinical impact of PET co-registered with CT (PET/CT).

Bone invasion in patients with oral cavity cancer: comparison of conventional CT with PET/CT and SPECT/CT.

Purpose: To prospectively compare the accuracy of helical contrast material-enhanced computed tomography (CT) with that of CT and positron emission tomography (PET) combined and CT and single photon emission CT (SPECT) combined in the detection of bone invasion in patients scheduled to undergo surgery for clinically suspected oral cavity carcinoma with possible bone invasion, with surgical results as the reference standard.

Materials And Methods: This study had local ethical committee approval, and all patients gave written informed consent. Thirty-four consecutive patients (17 men, 17 women; mean age, 64.

Is primary chronic osteomyelitis a uniform disease? Proposal of a classification based on a retrospective analysis of patients treated in the past 30 years.

Introduction: Primary chronic osteomyelitis of the jaw is a rare, non-suppurative, chronic inflammatory disease of unknown aetiology. To date, classification is confusing due to a non-uniform terminology. The aim of this study was to establish a simple (clinical) classification based on patient data from our clinic.

Staging of head and neck tumors: [18F]fluorodeoxyglucose positron emission tomography compared with physical examination and conventional imaging modalities.

Purpose: The aims of this study were to evaluate the use of [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) in the staging of primary and recurrent tumors of the head and neck in comparison to routine clinical methods (physical examination, ultrasonography, computed tomography) and to investigate the effect of FDG-PET scanning on therapeutic strategy.

Materials And Methods: Retrospective analysis of the results of FDG-PET and conventional diagnostic modalities were compared with biopsy results or patient outcome or both. In a period of 6 years, 78 FDG-PET studies were performed on 56 patients; 24 of them before therapy and 54 on suspicion of residual or recurrent tumor.

Pulpal response to Er:YAG laser drilling of dentine in healthy human third molars.

Background And Objectives: Maintenance of pulpal health is a critical prerequisite for successful application of light amplification by stimulated emission of radiations (lasers) in the hard tissue management of vital teeth. The purpose of this study was to investigate the short- and long-term pulpal effects to cavity-preparations in healthy human teeth using erbium-doped:yttrium, aluminum, and garnet (Er:YAG) laser.

Materials And Methods: A total of seven healthy third molars that were to be removed due to space-problem were used.
