Evaluation of calcium hydroxide mixed with propolis by ultrasonic activation as root canal dressing in delayed tooth replantation.

Background: In cases of tooth avulsion, in which the neurovascular bundle responsible for nourishing the dental pulp is break, endodontic treatment is necessary before proceeding with tooth replantation. In this process, various substances have been tested in combination with calcium hydroxide Ca(OH)2 in an attempt to improve its effectiveness. This study aimed to examine the effects of using a mixture of Ca(OH)2 and 10% propolis, with subsequent application of ultrasonic treatment, on the delayed replantation of teeth in rats.

Effects of different alcohol concentrations on the development of apical periodontitis in rats.

Aim: To investigate the effect of different alcohol concentrations on the development of apical periodontitis (AP) in rats.

Methods: Forty Wistar rats were arranged into five groups: (C) - control rats receiving sterile water as the only liquid; (G5) - animals receiving an alcohol solution at 5%, (G10) - alcohol solution at 10%, (G15) - alcohol solution at 15%, and (G20) - alcohol solution at 20%. The alcoholic solution or water was given to the groups as the sole source of hydration throughout the 30 days of the experiment.

Chronic alcohol consumption changes blood marker profile and bone density in rats with apical periodontitis.

Aim: The aim of the present study was to evaluate apical periodontitis (AP) development in rats under a chronic alcohol diet by calcium, phosphorus, and alkaline phosphatase blood levels in addition to histological and radiographic analyses.

Methods: Thirty-two rats were arranged into four groups: (a) group 1: without apical periodontitis and on a regular diet; (b) group 2: AP and on a regular diet; (c) group 3: alcoholic diet without apical periodontitis; and (d) group 4: alcoholic diet and apical periodontitis. Alcoholic solution at 20% was given throughout the 8-week experiment.

Orthodontic Extrusion as Treatment Option for Crown-Root Fracture: Literature Review with Systematic Criteria.

Objective: To review the literature searching for a consensus for the choice of orthodontic extrusion as treatment for crown-root fracture.

Materials And Methods: An electronic search was performed in the databases PubMed, Cochrane Central Register of Controlled Trials and Scopus and a manual search of the Journal Dental Traumatology.

Results: Forty articles were found in PubMed and 38 in Scopus and after removal of duplicate sample 51 contained articles.

Delayed tooth replantation in rats: effect of systemic antibiotic therapy with amoxicillin and tetracycline.

Systemic antibiotic therapy (SAT) has usually been recommended after tooth replantation, but its actual value has been questioned. As there are no reports in the literature about its influence on tooth replantation, the aim of this study was to evaluate the influence of systemic administration of antibiotics (amoxicillin and tetracycline) at the different phases of the repair process (7, 15, 30 days) in delayed rat tooth replantation. Ninety Wistar rats (Rattus norvegicus albinus) had their maxillary right incisors extracted and bench-dried for 60 min.
