This is a retrospective clinical study of 360 teeth diagnosed with pulpitis and treated locally with a combination of three antibacterial drugs (ciprofloxacin, metronidazole and minocycline, “3Mix-MP”) without a pulpectomy procedure. Consecutive patients with a clinical diagnosis of pulpitis had pre-operative factors collected (spontaneous pain, pulp exposure, depth of carious lesion) and were ...

OBJECTIVE To perform a systematic literature review and meta-analysis on the effectiveness of interventions used in the emergency management of acute apical periodontitis in the permanent dentition. METHODS Electronic databases were searched from their inception to 2001. These searches, combined with manual searching, yielded 1,097 citations, of which 92 were relevant. Independent application...

The purpose of this study was to analyze the inflammatory response of dog's periapical tissues to 17% trisodium EDTA salt (pH 8.0) and 1% citric acid (pH 2.0). Saline was used as a control. Six adult dogs were used as the biological model of the study. The experimental units comprised 56 roots of mandibular molars (first and second) and premolars (first, second and third). After coronal opening...

Although many clinicians focus on drugs for pain management, this is only one aspect of the clinician’s armamentarium for managing endodontic pain. Numerous studies indicate that various clinical treatments provide substantial benefit for relief of odontogenic pain. These clinical treatment options include pulpotomy, pulpectomy, incision and drainage, trephination, and occlusal adjustment for s...

The objective of this equivalency study was to see if a colony of Streptococcus mutans placed into cavities in primary molar teeth produced pulpitis similar to an established pulpitis induction method using carious dentine. In two juvenile baboons (Papio ursinus), occlusal cavities were cut in all 16 primary molar teeth, followed by making a small pulpal exposure after which the cavity was swab...

The aim of the present study was to provide a general scheme for pulpectomy of primary molars that may be useful for decision-making about negotiation of root canals and selection of appropriate instruments. A total of 160 vital primary molars in 85 patients (40 males, 45 females) aged 4-6 years were selected. After taking primary radiographs, local anesthesia was induced, and the teeth were is...

PURPOSE The purpose of this study was to compare clinical and radiographic success rates of zinc oxide-eugenol cement (ZOE) vs calcium hydroxide/iodoform paste (Vitapex) in pulpectomized primary molars at 6 and 12 months. METHODS Fifty-four mandibular primary molars from 42 children (average age 5.6 +/- 1.2 years) that met the inclusion criteria were allocated to either test material via bloc...

AIM   To compare the effects of single doses of three oral medications on postoperative pain following instrumentation of root canals in teeth with irreversible pulpitis. METHODOLOGY   In this double-blind clinical trial, 100 patients who had anterior or premolar teeth with irreversible pulpitis without any signs and symptoms of acute or chronic apical periodontitis and moderate to severe pai...

Seventy-three teeth with acute irreversible pulpitis were subjected to emergency pulpotomies. After removal of the coronal portion of the pulp, a sterile cotton pellet or zinc oxide-eugenol cement was placed against the remaining pulp tissue. The cotton pellet was either dry or moistened with camphorated phenol, cresatin, eugenol, or isotonic saline. This gave six different groups of treatment ...

The use of argon laser (488 nm) has been suggested as a new alternative for polymerizing adhesive materials. This study aimed to evaluate the tensile bond strength of a microfilled composite (A110, 3M) inserted by incremental technique (3 increments of 1 mm) and by single increment (3 mm) polymerized by argon laser for 10, 20 and 30 seconds and halogen light for 40 seconds. Eighty (8 groups of ...
