Tooth regeneration by cell delivery encounters translational hurdles. We hypothesized that anatomically correct teeth can regenerate in scaffolds without cell transplantation. Novel, anatomically shaped human molar scaffolds and rat incisor scaffolds were fabricated by 3D bioprinting from a hybrid of poly-epsilon-caprolactone and hydroxyapatite with 200-microm-diameter interconnecting microchan...

STATEMENT OF THE PROBLEM The use of miniscrews has expedited the true maxillary incisor intrusion and has minimized untoward side effects such as labial tipping. PURPOSE The aim of this study was to assess the stress distribution in the periodontal ligament of maxillary incisors when addressed to different models of intrusion mechanics using miniscrews by employing finite element methods. The...

BACKGROUND This article describes the management of a complicated crown root fracture. CASE REPORT A young patient presented with a crown root fracture of the maxillary left central incisor with an oblique subgingival fracture line. A multidisciplinary treatment approach including endodontic treatment, orthodontic extrusion, surgical extraction and intra-alveolar repositioning was used to gai...

The continuously growing rodent incisor is a widely used model to investigate odontogenesis and mineralized tissue formation. This study focused on evaluating the mouse mandibular incisor as an experimental biological tool for analyzing in vivo the capacity of odontoblast-like progenitors or bioactive molecules to contribute to reparative dentinogenesis. We describe here a surgical procedure al...

we report a rare case of a two-rooted maxillary central incisor, stressing the importance of three-dimensional imaging in treatment planning and conservative approach of management. endodontic treatment of this central incisor was carried out with a successful outcome.

Fusion is developmental anomaly of the dental hard tissue and is defined as the joining of 2 developing tooth germs resulting in a single large tooth structure. Different treatment methods can be used according to the requirements of the situation. The purpose of this case report was to present the multidisciplinary treatment of a patient who had a permanent maxillary left central tooth fused w...

Odontomas are a common type of odontogenic tumor, usually asymptomatic and mostly detected on routine radiographic examination. An 11-years-old male child with the chief complaint of mobility of deciduous dentition in the upper front region was diagnosed with an odontome with an impacted central incisor, missing lateral incisor and retained deciduous incisors following radiographic analysis. Hi...

The aim of this case report was to present the non-surgical root canal treatment of the geminated maxillary anterior lateral incisor tooth. A 50-year-old female patient was referred for endodontic treatment of her maxillary right lateral incisor. In the clinical examination, a large crown was observed in the right maxillary incisor region when compared with the left maxillary lateral incisor. T...

Macrodontia is a rare dental anomaly which consists on the presence of any tooth or teeth larger than the average. In the present report the case of a child with an uncommon true isolated macrodontia of a maxillary central incisor is presented. The maxillary left central incisor was considered a macrodontic tooth since its mesiodistal crown dimension was 12.41 mm while the mesiodistal crown dim...

AIM The purpose of this case report is to describe the combined surgical and orthodontic treatment of two cases with an impacted maxillary central incisor and canine in the same quadrant and to discuss the causal relationship between them. BACKGROUND The most common causes of canine impactions are usually the result of one or more factors such as a long path of eruption, tooth size-arch lengt...
