The purpose of this study was to assess the effects of the administration of zoledronic acid (ZA) during orthodontic movement in rats. A hundred and twenty male Wistar rats were applied force of 30 cN with spring closed nickel-titanium to move the upper right first molar to mesial. In the Control Movement group (CM), only tooth movement was performed; the Control Acid Zoledronic group (CAZ) rec...

Frequent occurrence of dental trauma in the early childhood often leads to persistence of immature nonvital tooth supplemented by periapical periodontitis as well as inflammatory external root resorption. Such teeth pose several difficulties in front of the clinician primarily due to absence of definite apical stop. The present case report highlights the nonsurgical endodontic management of a s...

This case report describes the treatment of a severe crown fracture of an immature mandibular permanent incisor in a 12 year-old boy referred to the Dental Traumatology Center of UNIGRANRIO University. After conventional endodontic procedures and dressing with calcium hydroxide, an apical plug was made with mineral trioxide aggregate in order to avoid an overflow of gutta-percha and endodontic ...

OBJECTIVE This article will review the new concept of regenerative endodontics in the management of immature permanent teeth. The potential role of stem cells to regenerate immature permanent teeth after conservative treatment will be discussed. DATA AND SOURCES Two sets of data source are focused in this review: (i) the characterization of various dental stem cells discovered since 2000 and ...

Periapical health is the primary goal of endodontic treatment in mature and immature teeth. In addition, the goals of treatment of immature teeth with arrested root development include root growth to length and maturation of the apex, as well as thickening of the canal wall. These goals are valid for immature teeth that have been subjected to trauma and dental caries or that are the result of d...

External inflammatory root resorption (EIR) represents a challenge in endodontic practice. EIR commonly occurs after dental trauma that results in periodontal ligament injury, pulp necrosis and subsequent infection.  Treatment of EIR is based on disinfecting the root canal system through chemomechanical procedures and then filling it with calcium hydroxide or triple antibiotic paste. Dental tra...

BACKGROUND The apexification is the first alternative treatment on a permanent tooth when, after a tooth trauma and in the presence of immature apex trauma, pulp necrosis occurs. Many studies have demonstrated the efficacy of mineral trioxide aggregate (MTA) as apical sealing material of choice in these cases, but has a degree of filtration as all other materials. The objective of this study wa...

Treatment of non-vital immature teeth with apical periodontitis has always been a challenge in Endodontics. Regenerative endodontic treatment (RET) has been successfully used for the management of these cases. The aim of this study is to present a case of RET used for the retreatment of a previously endodontically treated permanent tooth with an open apex. A 14-year-old boy with a poor endodont...
