Prediction of maxillary lateral-incisor root resorption using sector analysis of potentially impacted canines.
nine is the most frequently impacted tooth in the dental arch. Although the incidence of canine impaction is about 1 in 100 in the general popula tion,1 the ratio tends to be much higher in an ortho dontic practice—perhaps as high as 23.5%, ac cording to one researcher.2 Palatal impactions are more prevalent (85%) than labial impactions (15%).35 early detection of impactions is critical to...
متن کاملPredisposing factors for severe incisor root resorption associated with impacted maxillary canines.
INTRODUCTION Severe incisor root resorption (SIRR) associated with impacted maxillary canines is rare but has important implications. Early diagnosis and treatment are imperative. In this investigation, we aimed to identify predisposing factors for impacted canine-linked SIRR. METHODS Clinical and radiographic data of 55 consecutive patients (77 canines) with SIRR of 96 incisors were compared...
متن کاملCone-Beam Computed Tomography Evaluation of the Positions of Unerupted Maxillary Canines with Incisor Root Resorption
Purpose: To establish a new coordinate system using the incisive canal and incisive foramen in cases confirmed to have root resorption in the maxillary incisor region by cone beam computed tomography (CBCT) to investigate the positions of the central and lateral incisor roots and erupting maxillary canine tooth crowns in the horizontal plane. Methods: Nine patients (two males; mean age: 10.5 ye...
متن کاملDentoskeletal characteristics in patients with palatally and buccally displaced maxillary permanent canines.
The aim of this retrospective study was to analyse dentoskeletal characteristics in patients with eruption disturbances of the maxillary permanent canines. Pre-treatment panoramic radiographs and lateral cephalograms of 636 consecutive orthodontic patients were assessed. The control group included 456 patients with physiologically erupted maxillary permanent canines (261 females and 195 males, ...
متن کاملNo difference in surgical outcomes between open and closed exposure of palatally displaced maxillary canines.
PURPOSE To investigate differences in surgical outcomes between open and closed exposure for palatally displaced maxillary canines. MATERIALS AND METHODS This multicenter randomized controlled trial involved 2 parallel groups. The settings were 1 dental teaching hospital in and 2 hospital units near Sheffield, UK. Participants were younger than 20 years, had a unilateral palatally displaced m...
