“…Some authors still use the term oligodontia to describe the absence of many but not all the teeth. 32 Isolated hypodontia is relatively common and may occur sporadically, or it can be hereditary. In most cases, the missing teeth are the last in each series.…”

Dentists and oral and maxillofacial radiologists have used periapical, occlusal, panoramic, and cephalometric radiographs for many years for diagnosing dental anomalies, especially before orthodontic or surgical treatment. Cone beam computed tomography was developed in recent years especially for the dental and maxillofacial region. Thus it has become the imaging modality of choice for many clinical situations, such as the assessment of dental impaction and structural teeth anomalies or other associated diseases and disorders (e.g., Gardner's syndrome, cleidocranial dysplasia). This article reviews different aspects of dental impaction and its possible effects on adjacent structures such as external root resorption, marginal bone loss, as well as describing structural dental anomalies. It provides a systematic analysis of their characteristic features and imaging findings for general radiologists to achieve a precise diagnosis and an optimal interpretation.

The development process of tissue and organs in the living body is managed by genetic components and is affected by systemic diseases or environmental factors such as trauma, chemicals and radiation. Depending on the development phase that these factors occur, conditions such as deviations from normal growth and development, and the disruptions of tissue quantity and quality may occur. Disruption of the normal functioning of the amelogenesis steps for various reasons causes defections of enamel matrix formation, resorption, and subsequent calcification process. Clinically, this situation appears as defects characterized by features ranging from diffuse opacities to the complete absence of tooth enamel. Developmental enamel defects, the prevalence of which varies between 10% and 80%, cause problems that negatively affect individuals' quality of life, such as aesthetic problems, hypersensitivity, rapidly progressing caries, and tooth tissue loss. The aim of this study was to investigate the developmental enamel defects, their relationship with the development stages of the enamel, the etiological factors, in the light of current information. Clinical management of these defects and rehabilitation with minimally invasive approaches were evaluated with exemplary cases.

“…2 In GEH, the dentition is affected partially or wholly, and the defects can be seen on any surface of enamel but generally do not cover all surfaces of the crown. 9 GEH may adversely affect the individual's life quality by causing consequences such as caries, tooth wear and sensitivity, poor aesthetic and psychological disturbances. 1,2,7,8,10-13 Hence, well-known possible aetiological factors, multidisciplinary treatment approach and timely diagnosis are essential for the comprehensive and adequate treatment of these patients.…”

Ghrelin hormone might have a potential role in amelogenesis

Aims: Amelogenesis imperfecta and generalised enamel hypoplasia are developmental dental anomalies that affect dental enamel. While amelogenesis imperfecta results from various gene mutations, the exact underlying mechanisms of the etiopathogenesis of both remain unclear. This study aims to evaluate Ghrelin hormone levels in children with generalised enamel hypoplasia to establish whether Ghrelin might have a potential role in enamel hypoplasia's etiology. The second purpose is to determine the correlations among the blood levels of Ghrelin, growth hormone (GH), insulin-like growth factor-1 (IGF-1), bone alkaline phosphatase (BALP) and osteocalcin (OC) that are vital in dental development. Material and methods:Study was designed with two study groups, AI (hypoplastic amelogenesis imperfecta) (n = 15; mean-age 10.36 ± 1.90) and GEH (idiopathic generalised enamel hypoplasia) (n = 15; mean-age 10.42 ± 1.84), and a healthy control (n = 15; mean-age 10.39 ± 1.91) group. After fasting for 10-12 hours, simultaneous blood samples were collected; then, after centrifugation, serum and plasma were stored at −80°C until the day of analysis. Total Ghrelin levels of plasma and serum levels of GH, IGF-1, BALP and OC were measured using commercial ELISA kits.Results: Ghrelin levels of AI and GEH groups were significantly lower (P < .01) than the control group. Conclusion:This is the first study to reveal the decreased levels of Ghrelin in plasma of children with generalised enamel hypoplasia, suggesting a potential role for Ghrelin in amelogenesis. In order to determine its function in enamel formation, further studies should be carried out. The result of the present study suggests that paediatricians refer children with abnormal Ghrelin levels to a paediatric dentist to contribute to appropriate prophylactic and therapeutic interventions. Generalised enamel hypoplasia may also indicate possible abnormalities in Ghrelin levels for paediatricians.How to cite this article: Zorlu S, Aren G, Balci Ekmekci O.Ghrelin hormone might have a potential role in amelogenesis.
