Gemination is an anomaly in size, shape, and structure of the teeth. The primary dentition is more frequently affected, but gemination may occur in permanent dentitions, usually in the maxillary-incisal region. In geminated teeth, incomplete development of two teeth from a single bud results in a larger tooth crown with a single root and canal. In this study, a gemination case in a male patient...

STATEMENT OF PROBLEM Dilaceration is defined as a sudden change in the axial inclination of root or between the crown and the root of a tooth. There is no previous study evaluating its prevalence in south of Iran. PURPOSE This study evaluates the prevalence of root dilaceration on the basis of its location in dental arch in a sample of dental patients referring to Shiraz dental school, Iran. ...

A patient who had ectrodactyly, dry skin, exfoliative dermatitis, and hypodontia with peg-shaped teeth, but not cleft lip and palate, is described. Ectrodactyly with a tooth anomaly is recognized in both acro-dermato-ungual-lacrimal-tooth (ADULT) syndrome and ectrodactyly-ectodermal dysplasia-cleft (EEC) syndrome. These 2 syndromes are caused by heterozygous mutations in the transcriptional fac...

Background: Hypodontia is one of the frequently observed dental anomalies in which dentofacial esthetics, phonetics, mastication, self-esteem and quality life can be adversely affected. Awareness disproportionate tooth number important must considered by orthodontists while making treatment plans to achieve proper occlusion, overbite, overjet, order restrain oral health deterioration. The aim t...

The finding of conjoined teeth has long been recognized: with widespread disagreement over the most appropriate descriptive term for this anomaly. Recently, Yuen et a12 contended that when the etiology was not established, the term “double tooth was more appropriate than terms such as fusion and gemination. The anomaly has been reported to occur more frequently in the primary than in the perman...

OBJECTIVE The aim was to evaluate the prevalence and distribution of tooth number anomalies in a Turkish subpopulation. MATERIALS AND METHODS A population of 2722 patients (1532 females and 1190 males; mean age, 12.33 ± 2.5 years) was retrospectively examined to determine the prevalence and distribution of the hypodontia, oligodontia, and hyperdontia using panoramic radiographs. All permanent...

PURPOSE The aim of the present study was to investigate the prevalence of dental anomalies in a Turkish population according to the gender and age. MATERIALS AND METHODS A retrospective study was performed using panoramic radiographs of 2025 patients (885 males and 1140 females) ranging in age from 9 to 35 (mean age 25.61±10.04) years attending Department of Oral Radiology, University of Ista...

Dens Invaginatus is a dental malformation that poses diagnostic difficulties in the clinical context. This anomaly may increase the risk of pulp disease and can potentially complicate endodontic procedure due to the aberrant root canal anatomy. Compared to conventional radiographs, three-dimensional images obtained with Cone Beam Computed Tomography (CBCT) are invaluable in the diagnosis of the...

Introduction. "Dens invaginatus" is a dental anomaly which originates from the invagination of the ameloblastic epithelium into the lingual surface of the dental crown during the odontogenesis. It can cause early pulpal necrosis, abscesses, retention or dislocation of contiguous elements, cysts, and internal resorptions. It normally affects the upper lateral incisors. In the following study the...

Diverse morphological tooth deformities are found in various shapes, textures, and prevalence. They can be sporadic or syndromes, nutritional, environmental, genetic, and ethnic related. Most of these tooth-born (ie, patient born with the deformation) deformations (eg, shovel-shaped incisors, tuberculum Carabelli, variations in number and shape of cusps, dens invaginatus, taurodontism) have bee...
