Ectodermal dysplasia

INTRODUCTION : Ectodermal dysplasia syndrome is a large,heterogeneous group of inherited disorders , the manifestations of which could be seen in more than one ectodermal derivatives. Common syndromes : A. Hypohidrotic ED B. Hidrotic ED Etiology :   Ectodermal dysplasia syndrome results from aberant development of ectodermal derivatives in early embryonic life. Symptoms Teeth In the development of tooth buds frequently result in congenitally absent teeth (in many cases a lack of a permanent set) and/or in the growth of teeth that are peg-shaped or pointed . The enamel may also be defective . Cosmetic dental treatment is almost always necessary and children may need dentures as early as two years of age. Multiple denture replacements are often needed as the child grows, and dental implants may be an option in adolescence, once the jaw is fully grown. Nowadays this option of extracting the teeth and substituting them with dental implants is quite co...

Chronic Hyperplastic Pulpitis ( Pulp polyp )

A pulp polyp , also called as Chronic Hyperplastic Pulpitis, is found in an open carious lesion, fractured tooth or when a dental restoration is missing. Due to lack of intrapulpal pressure in an open lesion pulp necrosis does not take place as would have occurred in a closed caries case. Also a good vascular and immune supply is necessary, therefore found in adults. It is a productive pulpal inflammation where the development of granulation tissue is seen. Causes Causes of a pulp polyp include the following: Carious tooth with significant loss of tooth structure Loss of a dental restoration that results in pulpal exposure Fractured tooth due to trauma with a pulpal exposure Pulpal tissue with access to a good blood supply Possible hormonal (estrogen and progesterone) influence Clinical features : 1. Occurs mostly in children and young adults , who possess a high degree of resistance and reactivity. 2.It involves teeth with large,open carious lesions. ...

Macroglosia

Macroglossia, meaning large tongue, has been a documented anatomical anomaly for several centuries but remains an entity defined more by presentation than by strict cephalometric analysis. The earliest known written description of tongue lesions comes from the Egyptian Papyrus Ebers, originally thought to be from around 1550 BC. Obviously, tongue lesions have since been categorized by their etiologies. Macroglossia has an extensive list of possible causes. Its treatment has been largely surgical in the modern era. Problem Multiple studies have attempted to define macroglossia by objective measurements based on a variety of clinical and radiographic tests. However, because of the difficulty in performing these tests and because intervention is not based on measurements but on clinical presentation, macroglossia is most often diagnosed subjectively. Ueyama and others defined macroglossia as occurring when  of the following  criteria is met:extravasation o...
