This study compared the in vivo debridement efficacy of the step-back preparation versus a step-back/ultrasound preparation in the mesial root canals of vital human mandibular molars. Group 1 consisted of 15 teeth prepared with a step-back technique using intermittent irrigation with 5.25% sodium hypochlorite. Group 2 consisted of 23 teeth prepared with a(More)
This study histologically compared the in vivo debridement efficacy of the step-back preparation versus a step-back/ultrasound preparation in the mesial root canals of vital mandibular molars. Group 1 consisted of 17 teeth prepared with a step-back technique using intermittent irrigation with 5.25% sodium hypochlorite. Group 2 consisted of 17 teeth prepared(More)
The purpose of this study was to determine the anesthetic efficacy of a supplemental intraosseous injection of 2% lidocaine with 1:100,000 epinephrine in teeth diagnosed with irreversible pulpitis. Fifty-one patients with symptomatic, vital maxillary, and mandibular posterior teeth diagnosed with irreversible pulpitis received conventional infiltrations or(More)
BACKGROUND Data are sparse on the role of capsule endoscopy (CE) in classifying disease type, affecting patient management, and altering health outcomes in pediatric inflammatory bowel disease (IBD). In a retrospective cohort analysis of symptomatic pediatric patients with previously diagnosed IBD, we evaluated whether data from CE would result in the(More)
We have shown that activated partial thromboplastin time values in children are considerably longer than in adults, but the causes for this observation remained unclear. Therefore, we investigated the correlation between activated partial thromboplastin time values and concentrations of clotting factors, quotients and titers of the tissue thromboplastin(More)
OBJECTIVE The degree of pulpal anesthesia obtained with an ultrasound-assisted inferior alveolar nerve block was compared to that obtained with a conventional inferior alveolar nerve block for mandibular teeth to determine whether needle placement assisted by ultrasound results in more successful anesthesia. STUDY DESIGN Through use of a repeated-measures(More)
The purpose of this study was to investigate the ability of low-dose fentanyl to produce analgesia when administered via the periodontal ligament injection in teeth with symptomatic, inflamed pulps. All subjects presented for emergency treatment with moderate to severe pain and had a posterior tooth with a clinical diagnosis of irreversible pulpitis. Twenty(More)
