The term “impacted teeth” refers to dentition that is partly or completely impacted in bone or soft tissue after eruption should have been completed although eruption age is completed not replaced in dental arc. The most commonly impacted teeth in the anterior region are maxillary canines, while the prevalence of impacted maxillary incisors ranges from 0.06% to 0.2%. Impacted maxillary incisors...

BACKGROUND Malpositioning of the endotracheal tube within the airway leads to serious complications such as endobronchial intubation. Prediction of the correct depth of an endotracheal tube is important and should be individualized. The manubriosternal joint (MSJ) is on the same horizontal plane with the tracheal carina. We compared the straight length from the upper incisor to the MSJ in the f...

INTRODUCTION The fusion of permanent teeth is a development anomaly of dental hard tissue. It may require a hard multidisciplinary approach with orthodontics, endodontics, surgery and prosthetics to solve aesthetic and functional problems. CASE PRESENTATION A 20-year-old Caucasian man presented to our Department to solve a dental anomaly of his upper central incisors. An oral investigation re...

OBJECTIVE To investigate how bracket slot size affects the direction of maxillary anterior tooth movement when en-masse retraction is performed in sliding mechanics using an induction-heating typodont simulation system. METHODS An induction-heating typodont simulation system was designed based on the Calorific Machine system. The typodont included metal anterior and resin posterior teeth embe...

Hyperdontia is an increased number of teeth within the dental arches. This is of particular interest to pediatric dentists who commonly make the initial diagnosis. Most often a large portion of these teeth is completely embedded or impacted within the jaws and can be viewed only radiographically. Hyperdontia can occur on virtually every tooth-bearing surface. However, the most frequent is the m...

This prospective study was undertaken to determine the incidence of post obturation pain related to root canal treatment of asymptomatic non-vital maxillary central incisor teeth that were prepared and filled in one visit using two different manual rootcanal preparation techniques: the step-back and the step-down and to determine the relationship, if any between post obturation pain and root ca...

conclusion the relationship between calcification of teeth and maturation of cervical bones was significant. bone maturation can be predicted by using teeth calcification stages, especially in the second molar, first molar and lateral incisor. results correlations between the two stages were observed in the first and second premolars, canine and central incisors. all these correlations were sig...

BACKGROUND The aim of the study is to investigate the prevalence of talon cusps in a sample of Jordanians dental patients and their distribution among different types of teeth. METHODS The data were collected from radiographic examination of 3,024 periapical films showing 9,377 teeth from a random sample of 1,660 patients. A tooth was considered having talon cusp if there was a V-shape radiop...

Background: Dilaceration is a rare dental condition that can occur during tooth development, resulting in distortion of the normal axial relationship between crown and root. Although it affect any tooth, most commonly occurs permanent incisors, often as result trauma to primary predecessor. The impact even slight displacement incisor be significant, disrupting development follicles new teeth. D...
