INTRODUCTION Migratory cells via blood circulation or cells adjacent to the root apex may potentially participate in dental pulp tissue regeneration or renewal. This study investigated whether systemically transplanted bone marrow cells can contribute to pulp regeneration in a chimeric mouse model. METHODS A chimeric mouse model was created through the injection of bone marrow cells from gree...

Aim: Previous studies have demonstrated that orthodontic forces may injure dental pulp tissue via the apical foramen. The purpose of this study was to investigate the expression of various cytokines in pulp tissues of root apex after orthodontic tooth movement and compare the amount of internal root resorption in vital and pulp less rat teeth. Methods: Upper right first molars of 7-week Wistar ...

AIM The object of this study was the evaluation of the success rate of endodontic treatment of primary teeth with necrotic pulps performed through a partial pulpectomy and a chemical shaping. MATERIALS AND METHODS The study was conducted on 50 necrotic primary molars, with an oral fistula and a clinical and radiographical positive diagnosis. On each tooth the endodontic treatment was performe...

OBJECTIVE To perform a systematic review in which the clinical research question for primary teeth with irreversible pulpal pathosis was "how pulpectomies with zinc oxide eugenol (ZOE) paste performed compared to other materials in their clinical and radiographic outcomes after twelve months or more follow-up period. STUDY DESIGN A literature survey of the electronic database (1950-2010) used...

OBJECTIVE A comparative study is made of the histological effects of silver amalgam versus compomer (Dyract) 90 days after placement as retrograde filling materials in experimental animals. METHOD Six Beagle dogs were used, with total pulpectomy and orthograde material filling followed by periapical surgery of the 6 upper and 6 lower incisors (for a total of 72 teeth). Thirty-six teeth corres...

Study Design: Prospective randomized controlled trial Aim: The aim of the present study was to clinically and radiologically evaluate two root canal filling materials in infected deciduous teeth over a period of 6 months. Background data: Pulp treatment in deciduous teeth is challenging due to the complex anatomy of the root canal system. The limitations in biomechanical preparation and root ca...

INTRODUCTION The purpose of this study was to evaluate the effectiveness of autologous platelet concentrates (APCs) in promoting pulp and dentin regeneration in animal models. METHODS An electronic search was performed on MEDLINE, Embase, Scopus, SciELO, LILACS, and CENTRAL. Animal studies using APC as a root filling material after pulpectomy in mature or immature teeth were included. Article...

The success of root canal therapy is dependent not only on removal of infected pulp (pulpectomy) followed by root canal enlargement, but also on the pharmacological effects of intracanal medications. Various intracanal medications are used. Formaldehyde preparations such as formocresol were common in the past, but these are no longer used in Europe or the US due to the biological toxicity of fo...

UNLABELLED One of the primary objectives of endodontic treatment of teeth with pulp necrosis is the elimination of microorganisms from the root canal system, as effectively as possible, especially in cases with chronic periapical lesions. AIM The purpose of this study was to analyze the response of the periapical tissue of dogs' teeth with chronic periapical lesions to endodontic treatment pe...

The primary tooth pulpectomy is a common clinical procedure. The choice of filling material is important to the success rate, but antibacterial properties of such materials against organisms known to inhabit infected primary root canals have not been well documented. This study compared the antibacterial effectiveness of 10 materials: 1. Calcium hydroxide mixed with camphorated parachlorophenol...
