Supernumerary teeth occur frequently in permanent dentition, but they are rarely found in primary dentition. Supernumerary teeth of orthodox shape and size that resemble normal dentition are called 'supplemental teeth'. Supplemental teeth are less common than supernumerary teeth and are often overlooked because of their normal shape and size.Supplemental teeth may cause esthetic problems, delay...

PURPOSE This study compares the accuracy of space prediction for the unerupted permanent canines and premolars by a recognized method of mixed dentition space analysis (Moyers technique) vs estimation by simple visual observation (SVO). METHODS Twenty clinicians with varying levels of dental experience and training blindly assessed study models of 4 intact arches (2 maxillary and 2 mandibular...

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch, and incidence of molariform mesiodens in the maxillary midline is rare in permanent dentition and extremely uncommon in primary dentition. A midline supernumerary tooth in the primary dentition can cause ectopic or delayed eruption of permanent central incisors which will further alter occlusion and may compromise e...

A longitudinal complicated crown-root fracture of an unerupted permanent incisor following trauma to primary teeth is reported. The development of the affected permanent tooth was not disturbed during a follow-up period of six years. Traumatic injuries to primary teeth can be transmitted to the permanent dentition because of the close relationship between the apices of primary teeth and the dev...

Fusion is an anomaly manifested in both deciduous and permanent dentitions. Triple tooth refers to the union of three separate tooth entities. It can involve the normal dentition or supernumerary teeth. Triplication is rarely encountered in deciduous and permanent dentition with an incidence of 0.02%. The case presented herein describes a rare case of triplication in permanent maxillary incisor...

Amelogenesis imperfecta represents a broad spectrum of genetic diseases affecting enamel formation in both deciduous and permanent dentition. This paper describes different phenotypes of amelogenesis imperfecta in deciduous, mixed and permanent dentition and treatment options, including a novel treatment possibility for extracted anterior deciduous teeth. The results showed that diagnosis and t...

background: hypodontia is the most common dental anomaly and might cause clinical complications. the aim of this study was to assess the prevalence and pattern of congenital missing in the permanent dentition dentition (excluding third molars), among iranian orthodontic patients. materials and methods: in this descriptive cross-sectional study, all approved panoramic radiographs of 3374 orthodo...

Radicular cysts in the primary dentition are rare, whereas they are most commonly occurring in the permanent dentition. We present a rare case of a radicular cyst associated with a non vital deciduous maxillary canine tooth with a history of trauma. The permanent canine was impacted due to the cyst. After the enucleation of the cyst, we observed a spontaneous eruption of the permanent canine. O...

OBJECTIVE The purpose of this study was to determine and compare the prevalence and presentations of developmental defects of the enamel (DDE) in the primary and permanent dentitions of a group of healthy schoolchildren residing in Granada (Spain). STUDY DESIGN A total of 1,414 healthy schoolchildren were examined using modified DDE criteria for recording enamel defects. RESULTS The prevale...
