Surgical derotation is a method of placing a rotated tooth in normal alignment in a dental arch; surgically, immediately and permanently. It is a potentially convenient and cost-effective treatment modality as compared to conventional orthodontic procedure for rotated maxillary incisor with open apex. Here is a presentation of a severely rotated maxillary left permanent central incisor in a nin...

The development of alveolar bone adjacent to the tooth root during tooth eruption is not well understood. This study tested the hypothesis that predominantly woven bone forms adjacent to tooth roots during tooth eruption, but that this immature structure transitions to lamellar bone when the tooth comes into function. Additionally, bone resorption was predicted to play a key role in transitioni...

Traumatic dental injury is considered a public dental health problem because of a high childhood incidence, high treatment costs, and prolonged treatment time. Although management guidelines for traumatized teeth have been outlined, tooth loss following trauma is occasionally unavoidable. Here, we describe the successful interdisciplinary management of a traumatized central incisor in an 11-yea...

Complete debridement, thorough disinfection and optimal sealing of the root canal system are the major challenges associated with endodontic treatment of teeth with open apices. In such teeth, thin radicular dentinal walls are susceptible to fracture. To ensure a better prognosis in such fractured prone thin dentinal walls, internal radicular reinforcement with various adhesive materials like g...

The regenerative endodontic treatment (RET) of human immature permanent tooth with apical periodontitis using platelet-rich fibrin (PRF) has shown successful results in incisor. The purpose of this case series is to report four cases of the management of dens evaginatus in immature mandibular second premolars with apical periodontitis using PRF in regenerative endodontics. Four dens evaginatus ...

Dentigerous cyst is a type of odontogenic cysts and generally occurs in the ages of twenties or thirties. Dentigerous cyst always includes a tooth which cannot complete the eruption process and occurs around the crown by the fluid accumulation between the layers of enamel organ. In rare cases, dentigerous cyst occurs in the first decade of life and develops in an immature permanent tooth as a r...

The Editorial Board of the Journal of Endodontics has developed a literature-based study guide of topical areas related to endodontics. This study guide is intended to give the reader a focused review of the essential endodontic literature and does not cite all possible articles related to each topic. Although citing all articles would be comprehensive, it would defeat the idea of a study guide...
