Knowledge about the external and internal anatomy of the tooth is essential for successful dental practice. Anomalies in the tooth are often encountered which poses difficulties in dental treatments. As like any other tooth, mandibular first molars are also prone for anatomic malformations. One such anatomic variation is the presence of extra root distolingually. This distolingual root is calle...

This case report describes the management of an oblique crown-root fracture of maxillary left lateral incisor. After removal of the fractured fragment, endodontic treatment, the remaining tooth was provisionally restored. The tooth was then orthodontically extruded by 3 mm to raise the defect supraginigivally. Periondonal fibres were cut with a surgical blade. A metallic screw type post was ins...

PURPOSE The purpose of this study was to examine the patient- and treatment-related etiologic factors of external root resorption. MATERIALS AND METHODS This study consisted of 163 patients who had completed orthodontic treatments and taken the pre- and post-treatment panoramic and lateral cephalometric radiographs. The length of tooth was measured from the tooth apex to the incisal edge or c...

Literature review There is a paucity of information on the concise relationship between endodontics and orthodontics during treatment planning decisions. This relationship ranges from effects on the pulp from orthodontic treatment and the potential for resorption during tooth movement, to the clinical management of teeth requiring integrated endodontic and orthodontic treatment. This paper revi...

Teeth may require further management following root canal treatment because of persisting or new apical pathosis. Management must be based on the diagnosis of the presenting condition and the history of the previous treatment, particularly in relation to when it was completed. Most root-filled teeth with periapical pathosis should be re-treated in the first instance via a conventional orthograd...

introduction : dentin removal during root canal instrumentation creates a weaker root structure and increases its potential to fracture. the aim of this in vitro experimental study was to compare fracture resistance of teeth filled with gutta-percha, and resilon using two different techniques. materials and methods: this study was performed on 105 single-canal extracted maxillary incisors. samp...

introduction: pulpotomy of carious primary teeth with an exposed pulp is a common treatment option. pulpotomy has been conducted with various medicaments over the years. the aim of this study was to evaluate clinical and radiographic success of primary vital pulpotomy with proroot and root mta. materials and methods: in this randomized clinical trial, children aged between 3-7 years who met the...

Gemination or Schizodontism, a relatively uncommon dental anomaly, is characterized by a tooth with a bifid crown and a common root and root canal. It is commonly seen in primary dentition and gemination in a supernumerary tooth is a rare phenomenon. The purpose of this paper is to present an unusual case wherein gemination has occurred in a lingually placed mandibular supernumerary third premo...

Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...
