A female presented to the office with a chief complaint concerning the esthetics of the porcelain-fused-to-metal (PFM) crowns on her maxillary lateral incisors. The objective was to use contemporary materials and techniques to have them blend better with her natural dentition. The PFM crowns had been completed at different times during her life. She said they did not match each other or her adj...

Fusion is a developmental anomaly characterized by the union of two adjacent teeth. In this article we report a rare case of bilateral fusion of permanent mandibular second molars with supernumerary teeth. The rarity with which this entity appears, along with its complex characteristics, often make it difficult to treat. The endodontic management of one tooth is described, as well as the succes...

trauma to primary teeth can lead to devastating sequels in development of permanent successors. the disturbance may range from enamel hypoplasia and/or hypo-calcification to arrest of dental bud development. crown dilaceration of permanent teeth is one of the consequences of trauma to deciduous teeth mainly due to intrusion or avulsion. this report presents a mandibular central incisor with dil...

A 66-year-old man with multiple myeloma treated with zoledronic acid, melphalan, and prednisone after a tooth extraction developed severe osteonecrosis of the mandible that was nonresponsive to antibiotic therapy. A CT scan showed innumerable fragmented sequestra in the mandible and some adjacent soft tissue fullness around the mandible. The association between the use of bisphosphonates and os...

Dentigerous cysts form from accumulation of fluid between reduced enamel epithelium and the crown of an unerupted tooth. They cause several difficulties such as swelling, non-eruption of the involved teeth, and displacement of adjacent teeth, and thus require early detection and prompt treatment. Treatment ranges from marsupialisation to enucleation. Enucleation is rarely used in children compa...

Transposition of teeth is a severe problem, which usually affects the cuspid-first premolar area. It is frequently associated with other dental anomalies such as tooth agenesis, peg-shaped maxillary lateral incisors, retained deciduous teeth, malpositions of the adjacent teeth and other teeth malformations. This paper describes the orthodontic management with fixed appliances of a case of bilat...

The goal of this treatment was the surgical- orthodontic rescue of the impacted teeth in a large dentigerous cyst, in a growing patient, by fixed orthodontic appliances. Initial and final records and progress in treatment are shown. The Authors demonstrate that a good result my be reached in this cases even if initial position of the cyst-associated teeth is critical and translocation of an adj...

Classification: The following classification is based upon the inductive effect of one dental tissue upon another. In normal tooth development, it has been observed that ameloblastic epithelium exerts an influence upon the undifferentiated mesenchymal cell of the dental papilla "inducing" adjacent cells to further differentiate into odontoblasts. The odontoblasts then begin to form dentine. The...

As the number of aged people in the world is growing, the need to provide patients with tooth alternate through removable partial dentures is equally growing. There are adversarial effects that should be kept in mind which might disturb the remaining teeth; specially, the abutments and the supporting tissues. These effects might spread to the muscles of mastication and also to the supporting pe...

AIM To investigate the probability of and factors influencing tooth survival following primary (1°RCTx) or secondary (2°RCTx) root canal treatment. METHODOLOGY This prospective study involved annual follow-up of 2 (100%) to 4 years (50%) of 1°RCTx (759 teeth, 572 patients) and 2°RCTx (858 teeth, 642 patients) carried out by Endodontic postgraduate students. Pre-, intra- and post-operative dat...
