we present a case of unexpectedly prolonged motor and sensory block following a successful single injection ultrasound – guided infraclavicular block with bupivacaine (0.25%) and dexamethasone (8 mg). ultrasound guidance and safety measurement such as injection of the local anaesthetic at a slow rate and verifying that usual resistance was felt throughout the injection, has been applied. it too...

objectives: this study aimed to evaluate the location and characteristics of mental foramen, anterior loop and mandibular incisive canal using cone beam computed tomography (cbct). materials and methods: this retrospective cross-sectional study evaluated 200 mandibular cbct scans for the location of mental foramen, anterior loop prevalence and mandibular incisive canal visibility, its mean leng...

Inferior alveolar nerve block has a high failure rate in the treatment of mandibular posterior teeth with irreversible pulpitis. The aim of this study was to compare the anesthetic efficacy of 4% articaine, 2% lidocaine and 2% mepivacaine, all in combination with 1:100,000 epinephrine, in patients with irreversible pulpitis of permanent mandibular molars during a pulpectomy procedure. Sixty-six...

Nerve sheath myxoma has been described as a rare neural tumor arising from Schwann cells. It is observed most frequently in the central area of the face, neck and upper extremities. In the past the term neurothekeoma was used as synonym for nerve sheath myxoma but according to new reports, they are separate entities which can be confirmed by immunohistochemistry as in our case. Oral involvement...

Analgesia is essential for successful completion of modern dental procedures. Standard inferior alveolar nerve block (IANB) is the primary method used to achieve mandibular analgesia. Difficulty experienced in obtaining satisfactory analgesia after IANB, especially of an acutely inflamed mandibular molar, remains a common clinical problem. Even when a proper technique is employed, clinical stud...
