Master Day 2 Master Day 2 1. Identify “AOT” On radiographs, the adenomatoid odontogenic tumor presents as a radiolucency (dark area) around an unerupted tooth extending past the cementoenamel junction. It should be differentially diagnosed from a dentigerous cyst and the main difference is that the radiolucency in case of AOT extends apically beyond the cementoenamel junction. Radiographs will exhibit faint flecks of radiopacities surrounded by a radiolucent zone. It is sometimes misdiagnosed as a cyst. And frequently in anterior maxilla! 2. Identify Dentigerous Cyst 3.

  • The Role of Alpha V Beta 6 Integrin in Enamel Biomineralization
    The Role of Alpha v Beta 6 Integrin in Enamel Biomineralization by Leila Mohazab A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTERS OF SCIENCE in The Faculty of Graduate and Postdoctoral Studies (Craniofacial Science) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) October 2013 ⃝c Leila Mohazab 2013 Abstract Tooth enamel has the highest degree of biomineralization of all vertebrate hard tissues. During the secretory stage of enamel formation, ameloblasts deposit an extracellular matrix that is in direct contact with ameloblast plasma membrane. Although it is known that integrins mediate cell-matrix adhesion and regulate cell signaling in most cell types, the receptors that reg- ulate ameloblast adhesion and matrix production are not well characterized. Thus, we hypothesized that αvβ6 integrin is expressed in ameloblasts where it regulates biomineralization of enamel. Human and mouse ameloblasts were found to express both β6 integrin mRNA and protein. The maxil- lary incisors of Itgb6-/- mice lacked yellow pigment and their mandibular incisors appeared chalky and rounded. Molars of Itgb6-/- mice showed signs of reduced mineralization and severe attrition. The mineral-to-protein ra- tio in the incisors was significantly reduced in Itgb6-/- enamel, mimicking hypomineralized amelogenesis imperfecta. Interestingly, amelogenin-rich ex- tracellular matrix abnormally accumulated between the ameloblast layer of Itgb6-/- mouse incisors and the forming enamel surface, and also between ameloblasts. This accumulation was related to increased synthesis of amel- ogenin, rather than to reduced removal of the matrix proteins. This was confirmed in cultured ameloblast-like cells, which did not use αvβ6 integrin as an endocytosis receptor for amelogenins, although it participated in cell adhesion on this matrix indirectly via endogenously produced matrix pro- teins.

It can occur alone (isolated) or it could be associated with syndromes such as Down’s syndrome. It is uncommon in primary teeth. However, the permanent teeth are more likely to be affected with the most commonly affected teeth to be the third molars followed by mandibular second premolars, maxillary lateral incisors, maxillary second premolars, and mandibular central incisors. 2- Oligodontia: It is a term used to describe the developmental absence of more than six permanent teeth. It is also uncommon in primary teeth; and when the permanent 11/04/2019 2 teeth are affected, collapse of the dental arch and drifting of the few present teeth will result due to presence of excess space. Treatment of both hypodontia and oligodontia involve prosthodontic and orthodontic rehabilitation.

  • Day 2 Unicorn 1
    MasterDay2 A word from the author: MasterRQs and MasterDay2 are helpful only once you have basic knowledge of your subjects. Both of these files have the best and compile almost all radiographic images and cases available online. Extensive image coverage of each of topic has been done. Day 2 tests your basic knowledge of the subjects. I sincerely advise you to go through the mentioned topics properly- as the cases are mostly focussed on these. Know these diseases and medicines used, contraindications of them and MOA. What to note/write on the paper provided in the exam ? You will be given 2 sheets to write on/if anything. Here is what you need to write. Draw a line in the centre of the first page, and write Generic name on one side and Trade name on another. During the exam in the first 4-5 cases they mention you both the class/Drug/generic name and the trade name eg : Generic Trade Alendronate (Bisphosphonates) Fosamax Ethambutol (Anti TB) Abitol Zoledronic acid(Bisphosphonates) Reclast By the time you are done with 4-5 cases they will skip the Generic names in few questions because they presume you should know them as they have been mentioned in the exam only. So If you are unaware of this, you will have to go back and look for the important information again question by question, but if u have made this small chart, it saves your time! Must read topics 1. Hypertension and management 2. Myocardial infarction 3. Stroke 4. Diabetes 5. Syncope 6.

The shape of these microdonts is also often altered with the reduced size. This phenomenon is most commonly seen with maxillary lateral incisors, in which the tooth crown appears cone or peg shaped, (peg lateral). Macrodontia Generalized macrodontia is characterized by the appearance of enlarged teeth throughout the dentition. This may be absolute, as seen in pituitary gigantism, or it may be relative owing to a disproportionately small maxilla and mandible. Focal, or localized, macrodontia: is characterized by an abnormally large tooth or group of teeth.

  • Oral Pathology Disorders of Development of Teeth
    Oral Pathology DEVELOPMENTAL DEFECTS OF THE ORAL AND MAXILLOFACIAL REGION Developmental disturbances of the oral region are of these broad categories: (1) Developmental disturbances affecting teeth. (2) Developmental disturbances limited to soft tissue. (3) Developmental disturbances affecting bone. Disorders of development of teeth The development of teeth is regulated by genes, but the genetic program is very sensitive to disturbances in the environment such as infection, or toxic chemicals. The causes of developmental disorders of teeth are multifactorial, involving the interaction of genetic and environmental factors. These disorders may be prenatal or postnatal in origin and may inherit or acquired. Disorders of development of teeth may be due to abnormalities in the differentiation of the dental lamina and the tooth germs, causing anomalies number, size, form of teeth and abnormalities of morph differentiation or abnormalities in the formation of the dental hard tissue resulting in disturbances in tooth structure ((abnormalities of histo differentiation)). Developmental Alterations in the Number of Teeth Anodontia Absence of teeth is known as anodontia. This condition is further qualified as complete anodontia, when all teeth are missing; as partial anodontia or hypodontia, when one or several teeth are missing; as pseudoanodontia, when teeth are absent clinically because of impaction or delayed eruption; or as false anodontia, when teeth have been exfoliated or extracted. Partial anodontia is relatively common. Congenitally missing teeth are usually third molars, followed by second premolars and maxillary lateral incisors. 1-several regulatory genes are involved in tooth formation and development which may be mutated in hypodontia e.g. (MSX1 and Pax9). These genes are involved in the control of development of the face and of many other tissues and organs in the embryo.
