Dental anomalies are the formative defects caused by genetic disturbances or environmental factors during tooth morphogenesis. Simultaneous occurrence of various multiple anomalies has been reported previously, particularly in cases of chromosomal abnormalities that often manifest with multisystem involvement. Very few cases of multiple anomalies have been documented in patients with no known g...

A two-year, 2-month old girl with Ehlers-Danlos syndrome Type VII is described. The patient presented with bleeding after tooth brushing, and exhibited microdontia and yellow discoloration of teeth. She had carious teeth, but did not exhibit periodontal disease, poor wound healing after extraction, radiographic evidences of pulp stones, or malformed roots. Microscopic examination of a decalcifi...

Dentists and maxillofacial surgeons may occasionally encounter various dental anomalies in number, shape, size, eruption, etc. In particular, microdontia is relatively rare. Computed tomography during clinical dental examination is essential for early detection of these anomalies.

background & aim: the artificial teeth are produced with same standards for all the ethnics and countries in the world. the purpose of this study was to establish a normative size distribution in a group of students and staffs of shahid beheshti university of medical sciences. methods & materials: 320 individuals participated in this descriptive study. a vernier caliper was used to measure the ...

Developmental anomalies of tooth are not uncommon to find in clinical practice these days. Thorough knowledge of these anomalies is a prerequisite for their correct diagnosis, understanding clinical complications and management. Maxillary lateral incisor is one which is frequently associated with such developmental malformations, commonly affected by microdontia, hypodontia, dens invaginatus an...

Background Tooth abnormalities are most often present in individuals with oral clefts than general population, and lead to a long-term impact on facial anatomy and self-esteem. The purpose of this study was to compare the proportion of dental anomalies between the cleft side and non-cleft side in individuals with non-syndromic unilateral alveolar clefts (AC). Material and Methods Twenty cone ...

AIM Human Severe Combined Immunodeficiency (SCID) is a prenatal disorder of T lymphocyte development that depends on the expression of numerous genes. Juvenile myelomonocytic leukemia (JMML), previously known as juvenile chronic myeloid leukemia (JCML), is a rare, myelodysplastic/myeloproliferative disease typically presenting in early childhood. CASE REPORTS Two cases are described of immuno...

Introduction: The number, size, shape, and structure of teeth in humans show very wide variation among different populations and sometimes within the same population. The aim of the present study was to determine the prevalence of developmental dental anomalies among patients attending the faculty of dentistry in Rasht, Iran over a period of seven months. Materials and methods: This cross-se...

OBJECTIVES The purpose of this study was to evaluate the clinical and radiographical characteristics of non-syndromic hypodontia and hyperdontia in the permanent dentition. STUDY DESIGN This study included 139 patients. Clinical and radiographical examinations were carried out by two examiners. Number and localization of missing or supernumerary teeth, and pathologies associated with the teet...
