Comparative StudyAn ex vivo comparison of pressures within dental pulp space using conventional anesthetic technique versus needle-mounted obturator.
The intrapulpal (IP) injection technique is 1 of several ways of obtaining profound anesthesia. There is evidence to suggest that pressure is the primary factor in obtaining anesthesia using IP injection. This is an ex vivo comparison of pressures within dental pulp space using the conventional anesthetic technique versus a needle-mounted obturator technique. ⋯ IP injection with the obturator resulted in increased pressure at the apex of each tooth. This pressure increase may allow for increased anesthesia when IP injections are indicated.

Randomized Controlled Trial Comparative StudyEfficacy of articaine versus lidocaine as a supplemental buccal infiltration in mandibular molars with irreversible pulpitis: a prospective, randomized, double-blind study.
Profound pulpal anesthesia in mandibular molars with irreversible pulpitis (IP) is often difficult to obtain and often requires supplemental injections after an ineffective inferior alveolar nerve block (IANB). The purpose of this prospective, randomized, double-blind study was to compare the efficacy of 4% articaine with 2% lidocaine for supplemental buccal infiltrations (BIs) after an ineffective IANB in mandibular molars with IP. In addition, the use of articaine for IANB and intraosseous injections was investigated. ⋯ Supplemental BI with articaine was significantly more effective than lidocaine. The IANB success rate of 4% articaine confirmed published data.

Review Case ReportsOrbital, mediastinal, and cervicofacial subcutaneous emphysema after endodontic retreatment of a mandibular premolar: a case report.
Subcutaneous emphysema (SCE) rarely occurs from endodontic treatment. Most reported cases of iatrogenic SCE occur in the cervicofacial region. Only a few cases have been reported of SCE extending into the mediastinum or orbital spaces. In the present report, we describe a concomitant occurrence of orbital, mediastinal, and cervicofacial SCE immediately after endodontic retreatment. ⋯ SCE may go undetected or misdiagnosed. Complications may be fatal. Therefore, clinicians should apply preventive measures and know how to identify and manage SCE. We review reports of SCE in the last century, discuss etiology and differential diagnosis, and present recommendations for prevention and management of SCE.

Comparative StudyRole of ultrasonography in differentiating facial swellings of odontogenic origin.
Differentiating an acute, odontogenic facial swelling clinically as cellulitis or an abscess has not been thoroughly investigated in endodontics. It has been suggested in the medical and dental literature that the use of ultrasound may aid in differentiating cellulitis from an abscess. Therefore, if ultrasound were more accurate than a blind incision for drainage procedure in locating purulence, perhaps the outcome of the incision for drainage procedure would be beneficial in the resolution of odontogenic infections. The purpose of this prospective study was to compare clinical examination plus ultrasonography versus clinical examination alone in differentiating cellulitis from abscesses in patients with facial swelling of odontogenic origin. ⋯ The addition of ultrasonography to a clinical examination did not significantly increase the number of correct diagnoses.

Randomized Controlled Trial Comparative StudyEffect of preoperative acetaminophen/hydrocodone on the efficacy of the inferior alveolar nerve block in patients with symptomatic irreversible pulpitis: a prospective, randomized, double-blind, placebo-controlled study.
The purpose of this prospective, randomized, double-blind, placebo-controlled study was to determine the effect of the administration of the combination acetaminophen/hydrocodone on the anesthetic success of mandibular posterior teeth in patients experiencing symptomatic irreversible pulpitis. ⋯ A combination dose of 1000 mg acetaminophen/10 mg hydrocodone given 60 minutes before the administration of the IAN block did not result in a statistically significant increase in anesthetic success for mandibular posterior teeth in patients experiencing symptomatic irreversible pulpitis.
