303 T JOB Spring (the acronym is formed from the names of the last three authors of this article) was developed to facilitate correction of partial canine-first premolar transposition in the maxillary arch.1-6 This new device helps move the premolar toward the center of the palate to allow mesial displacement of the canine. The spring is attached to the archwire and can be activated either outs...

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...

Dental anatomical variations play a significant role in the diagnosis and a successful treatment outcome in endodontics. It is essential for the clinician to have a clear picture and understanding of the pulpal anatomy and its variations. In a mandibular second premolar, it is rare to find extra roots and canals. The aim of the present article is to report a case about the successful diagnosis,...

Transposition may affect both sexes equally and, although it may occur in the maxilla or in the mandible, the frequency of maxillary permanent canine involvement is the greatest [3]. In the maxilla the canine is transposed most frequently with the first premolar (Figure 1a,b), less often with the lateral incisor followed rarely by central incisor or second premolar In the mandible transposition...

The maxillary first premolar may present large number of anatomic variations. The clinician should be aware of the configuration of the pulp system. Maxillary first premolars usually have two canals. The incidence of three canals in these teeth is quite rare. This case report presents the diagnosis and clinical management of a maxillary first premolar with two distinct canals in the apical thir...

accurately localizing the mental foramen and mandibular canal is important when administering local anesthesia and performing surgery; therefore, knowing the normal range of the possible locations is essential. our purpose was to assess the location of the mental foramen and mandibular canal in an iranian population using panoramic radiography.standard panoramic radiographies were performed. th...

This study was conducted on a sample of thirty patients selected from Orthodontics department de’Montmorency College of dentistry/ Punjab dental Hospital, Lahore. The purpose of study was to evaluate treatment effects of Distal Jet Appliance during Class-II molar correction with a focus on the magnitude of Maxillary first molar distalization, its tipping, extrusion, rotation as well as anchorag...

Running title: Root and canal morphology of maxillary first premolar teeth Abstract Aim : To determine the variations in the root and canal morphology of the maxillary first premolar teeth in a Ugandan population. Methodology : Extracted maxillary first premolar teeth (n = 202) were evaluated in this study. The specimens had their pulp chambers de-roofed. They were decalcified in nitric acid an...

Overeruption of maxillary molars due loss of opposing teeth creates occlusal and functional interferences. Before reconstruction can be initiated, intrusion of overerupted molars becomes essential. This report illustrates treatment of overerupted maxillary premolar and molar via direct use of miniscrew anchorage. A 24-year old female had lost first and second left mandibular molars due to pulpa...
