BACKGROUND In individuals with simple hypodontia, congenital absence of teeth commonly affects just one tooth of a pair, not both. However, patterns of hypodontia have not been fully explored in children with Down syndrome (DS). OBJECTIVE We describe the frequency and left-right symmetry of hypodontia in the permanent dentition of 8- to 9-year-old Norwegian children with DS. MATERIALS AND M...

BACKGROUND Ovarian cancer is usually diagnosed in an advanced stage and the present clinical and diagnostic molecular markers for early OC screening are insufficient. The aim of this study was to identify potential relationship between the hypodontia and epithelial ovarian cancer (EOC). PATIENTS AND METHODS A retrospective study was conducted on 120 patients with EOC treated at the Department...

Objective. Patients with hypodontia are relatively common in clinical dentistry. This study was performed to determine the prevalence of hypodontia of permanent teeth in Korean orthodontic patients and whether such prevalence is associated with the type of dental clinic, patient gender, or the type of malocclusion. Materials and Methods. Over a five-year period, we evaluated 3,055 patients (mea...

The purpose of this article is to describe a team approach to treatment of hypodontia in adolescent dentition. A case report of hypodontia with a microdontic lateral incisor in a Class I malocclusion illustrates the principles of case management. Multidisciplinary consultation during treatment planning and coordination and appropriate timing of subsequent interdisciplinary dental care enables t...

The present study deals with the statistical evaluation of the number of congenitally missing teeth, of the affected dental groups, of the clinical forms and of hypodontia topography, performed on a group of patients from the North‐Eastern region of Romania, examined in the Ambu‐ latory of the “Sf. Spiridon” Universitary Emergency Hos‐ pital of Iaşi, between 1990‐2012. 111 patients (51 boys and...

OBJECTIVE The aim of this study was to document the prevalence of hypodontia in the permanent dentition among a group of Turkish sample who sought orthodontic treatment and to compare present results with the specific findings of other populations. The occurrence was evaluated in relation to gender, specific missing teeth, the location and pattern of distribution in the maxillary and mandibular...

OBJECTIVE The aim of this retrospective study was to assess the prevalence and distribution of hypodontia in the permanent dentition in a sample of Turkish patients who referred to the Ankara Dental Hospital for orthodontic treatment. MATERIALS AND METHODS The pre-treatment orthodontic records of 2530 patients, 1382 girls (54.62%) and 1148 boys (45.38%) between the chronological ages of 7 and...

Tooth agenesis is one of the most common congenital malformations in humans. Hypodontia can either occur as an isolated condition (non-syndromic hypodontia) or can be associated with a syndrome (syndromic hypodontia), highlighting the heterogeneity of the condition. Though much progress has been made to identify the developmental basis of tooth formation, knowledge of the etiological basis of i...

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...

The hypodontia of a permanent tooth from a dental group represents a normal evolution in human dentition morphology. Nevertheless, the hypodontia of two teeth within a dental group is a rare developmental anomaly when not associated to a systemic syndrome. The aim of this study was to report two rare cases of four maxillary premolars hypodontia, not including the third molar, of two white women...
