Dental lamina cyst PDF

cysts arise from the dental lamina. The epithelial rem-nants of dental lamina have the capacity to proliferate, keratinise and form small cysts. Moskow and Bloom16 noted proliferative tendency in the dental lamina, having multiple areas of microcyst formation and keratin production in the human fetus as tooth development progressed the dental lamina. They are benign and usually disappear within the first three months of life. Sometimes they are mistaken by eruption cysts. They are also similar in appearance to Epstein's pearls [13,14]. Causes of Dental Cyst The causes and sources that cause dental cysts in most cases are Dental Lamina Cyst • Usually seen on the crest of the alveolus • Remnants of the dental lamina. • Tx - no treatment. K. Kohli, DDS Congenital Epulis of the Newborn • Relatively rare, seen in neonates(at birth), of unknown origin, with proliferation of mesenchymal cells. • Equal distribution between mx and md. • Females > males Abstract Dental lamina cyst or alveolar cyst is a commonly diagnosed developmental anomaly in the mouth of newborns. They are quite often mistaken as natal teeth if present in the lower anterior region. Although the prevalence is high, they are rarely seen because of the transient nature of the lesions

Odontogenic cysts originate from the epithelium of the developing teeth. The epithelium arises from the enamel organ, the cell rests of Malassez, the reduced enamel epithelium or the remnants of the dental lamina. The epithelial rests can also cause the formation of a residual cyst after the extraction of a tooth (1). The ter OralSurgery 548 DentalUpdate July/August 2015 Odontogenic Cysts - An Overview Abstract: This article aims to discuss the clinical features, radiological assessment, histopathology and management of a variety of odontogenic cysts. It also highlights the reclassification of odontogenic keratocysts to keratocystic odontogenic tumours A dentigerous cyst forms within the lining of the dental follicle when fluid accumulates between the follicular epithelium and the crown of the developing or unerupted tooth. Most dentigerous cysts manifest in adolescents and young adults and often form around the crown of an unerupted mandibular third molar. Patients are typically pain free odontogenic cyst that arises from the dental lamina. The epithelium in OKC appears to have innate growth potential similar to some benign tumors. 7 Odontogenic Keratocyst (OKC)! First reported by Philipsen in 1956 !

The dental lamina cyst, also known as gingival cyst of newborn, is considered a true cyst because it is lined by thin epithelium with a lumen usually filled with desquamated keratin and occasionally inflammatory cells[6, 7].These cysts can easily be wrongly diagnosed as natal teeth, especially if they are located in the newborn's mandibular anterior ridge gingival cyst arises from rests of soft tissue rather than rests of dental lamina. The LPC is lined by a thin, non-keratinized epi-thelium. Clusters of clear cells may be noted as nodu-lar thickenings within the cyst lining. These cells con-tain aggregates of glycogen, which can be demon-strated with appropriate stains. It is less common tha

In 1967, according to histogenesis and location in th Gingival cyst, also known as Epstein's pearl, is a type of cysts of the jaws that originates from the dental lamina and is found in the mouth parts. It is a superficial cyst in the alveolar mucosa.It can be seen inside the mouth as small and whitish bulge. Depending on the ages in which they develop, the cysts are classified into gingival cyst of newborn (or infant) and gingival cyst of adult Conclusions The vitality of pulpal dental elements involved and the gingival perodontal should always be checked. The determining point that supports this theory is the presence of clear cells in the epithelial boundary of these cysts, similar as in the dental lamina. Dansk Endodontiforening Hindsgavl Slot d.

Lateral periodontal cyst (LPC) is one of the developmen - tal odontogenic cysts with dental lamina rests origin. Histopathologic evaluation shows that the cystic cavity is lined by thin stratified squamous epithelium and in some area, by focal nodular thickening (14). Most of the lesions are asymptomatic. This lesion can b of Serres, which are remnants of the dental lamina; and (4) the tooth germ itself, which includes the enamel organ, dental papilla, and dental sac. For example, an increased space between the crown of an unerupted tooth and the surrounding reduced enamel epithelium is frequently an early indication of cyst or tumor formation (Fig. 78-9) The histogenesis of this cyst is still unclear. Zhu suggested that while the KCOT may arise from the dental lamina with the presence of the dental papilla required for its development, the OOC may arise from oral epithelium under the influence of dental papilla or only the oral epithelium.[9] Vuhahula et al the dental lamina or basal lamina. Controversies surrounding this cyst have been going on for a decade long when the WHO renamed it as keratocystic odontogenic tumor in 2005.[5] This was due to its tumor-like aggressive behavior and presence of PTCH gene

According to the histopathological description, most of the part of the cyst lumen is lined by a definite nonkerati-nized epithelium that may be reduced enamel epithelium, and hence there may be a possibility of origin of cyst from it. 6 On the other hand, Wysocki et al (1980) have proposed tha sion cysts, which are the oral counterparts of con-genital milia.

keratocysts originating from remnants of the dental lamina have an aggressive clinical behavior and a high recurrence rate, unlike the other odontogenic cysts19. The anatomopathological examination results confirmed a keratocyst, based on its characteristics of epidermoid cyst with hyaline cartilage. This type of cyst were odontogenic.9,11 Botryoid odotogenic cysts may thus arise from remnants of the dental lamina, from remnants of the reduced enamel epithelium, or from the root sheaths of Hertwig. Proliferation and cystic change in several epithelium rests may give rise to the polycystic character of botryoid odontogenic cysts.9,11,1
