INTRODUCTION The purpose of this study was to compare the anesthetic efficacy of 0.5% bupivacaine with 1:200,000 epinephrine with that of 2% lidocaine with 1:100,000 epinephrine during pulpectomy in patients with irreversible pulpitis in mandibular posterior teeth. METHODS Seventy volunteers, patients with irreversible pulpitis admitted to the Emergency Center of the School of Dentistry at th...

UNLABELLED Intracanal medication in pulpectomy therapy is used between appointments with the objective of reducing pain and inflammatory processes in pulp and periapical tissues. Propolis has been known as a natural antibiotic and has been subject of medical and dental research due to its therapeutic properties such as antibiotic, analgesic and anti-inflammatory effects. OBJECTIVE The aim was...

AIMS The aim of this study was to evaluate the effectiveness of two different varieties of electronic apex locators and radiovisiography (RVG) for working length determination in primary teeth. MATERIALS AND METHODS A total of 30 primary teeth indicated for pulpectomy in children aged 3 to 8 years were randomly selected and subjected to working length determination using two varieties of elec...

Pulp exposures secondary to caries are the most common in primary teeth due to the relatively large size of pulp chamber. Pulp in primary teeth is capable of healing, following control of infection and inflammation. Pulpotec and LSTR are the simple noninstrumentation endodontic treatment procedures which are capable of compensating for the inconvenience caused by conventional pulpectomy, and th...

Background and aims. The superiority of rotary systems has been reported in several clinical studies on permanent teeth. This study consisted of radiographic assessment and chair time of rotary instruments in the pulpectomy of primary second molar teeth. Materials and methods. In this randomized controlled clinical study, 46 children, 3-6 years of age, were selected. The patients were divided r...

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...

The aim of this study was to evaluate, histopathologically, the effectiveness of mechanical preparation of root canals using different irrigating solutions in dog teeth filled with LPS after pulpectomy. A total of 120 root canals of 6 mongrel dogs were filled with a solution of LPS after pulpectomy. The irrigating solutions used were saline, 1, 2.5, and 5% sodium hypochlorite, and 2% chlorhexid...

The purpose of this study was to evaluate the relative amount of root resorption in nonvital primary teeth after treatment with a 1-appointment formocresol pulpectomy. Thirty-seven children ranging in age from 2 years, 10 months to 8 years, 10 months received 41 pulpectomies in nonvital primary molars. At an initial follow-up examination, 6-36 months posttreatment (mean = 21 months), 80.5% (33/...
