bilateral intraosseous migration of mandibular second premolars in a patient with nine missing teeth
intraosseous migration is an unusual developmental dental anomaly, which demonstrates horizontal movement of unerupted teeth only affecting the permanent dentition of the lower jaw. mandibular second premolar is the most common impacted tooth after the third molars and maxillary canines. distal migration of the second premolar is rare and early loss of the permanent first molar is one of the mo...
Purpose: The aim of this cross-sectional study was to evaluate the impact different body mass index status on dental caries, tooth development, and eruption regarding development tissues health problems. 
 Materials & Methods: One-hundred-seventy-six children, aged between 3-12 years old, were included in distributed into 4 groups (n:44) according their as underweight, healthy, overwei...
BACKGROUND AND AIMS Hypodontia is a common developmental abnormality of dentition. This study aimed to determine tooth width in patients affected with mild hypodontia and compare the results with a control group without tooth agenesis. MATERIALS AND METHODS The orthodontic records of 25 patients with congenital missing of one or two teeth (hypodontia group), and 25 subjects with full dentitio...
Congenitally missing teeth are frequently presented to the dentist. Interdisciplinary approach may be needed for the proper treatment plan. The available treatment modalities to replace congenitally missing teeth include prosthodontic fixed and removable prostheses, resin bonded retainers, orthodontic movement of maxillary canine to the lateral incisor site and single tooth implants. Implants a...
Tooth agenesis is defined as congenital absence of one or more teeth in primary or permanent dentition and is a common oral variation that affects a large population group. Among the missing one’s, maxillary lateral incisor is more frequent causing esthetic and functional impairments in the affected individual. It might be associated with systemic problems, syndromic conditions or other oral an...
Background and Aims: The main purpose of orthodontic treatment is normal positioning of teeth in three dimensional plans, including the mesiodistal inclination. In this study, mesiodistal axial inclination of posterior teeth in skeletal class II was evaluated and compared with that of posterior teeth in skeletal class I. Materials and Methods: Seventy-eight panoramic radiographs for subjects be...
Missing tooth in the anterior region of maxilla lies aesthetic zone and create quite noticeable discrepancies. With a paradigmshift patient expectations towards functional as well aesthetically appealing replacements for edentulism, implant basedoral rehabilitation has emerged sole winner fulfilling all aspects needs.

J. he loss of a permanent anterior tooth on a young patient poses unique problems in replacement for the pedodontic practitioner. Full crown coverage of the abutment teeth necessary for conventional fixed bridgework is often contraindicated due to the large size of the pulp chamber and the potential for pulpal damage. Even if possible, this reduction violates the current concepts of good conser...
Foreign body aspirations that are not recognized at the time of aspiration can lead to insidious symptoms that can present a diagnostic challenge. We report the case of a 70-year-old man presenting with postobstructive pneumonia 2 months after aspirating his own tooth during a meal. He had been mistakenly diagnosed with asthma and treated with bronchodilators before a computed tomography scan o...
Single-tooth replacement may be effected through various methods, including the use of a resin-bonded fixed partial denture, a conventional fixed partial denture, and a single implant-supported crown. Although the introduction of newer therapeutic modalities, surgical and restorative techniques, and restorative materials has significantly expanded available treatment options, a greater demand i...
