There are three major categories of odontogenic cyst: dentigerous cysts, keratocystic odontogenic tumors, and radicular cysts.

Conclusion: The study demonstrates that radicular cyst was the most common odontogenic cysts followed by dentigerous and odontogenic keratocysts respectively in our study sample.
2) Ameloblastomas arise in dentigerous cysts or in others in which the neoplastic ameloblastic epithelium is preceded temporarily by a nonneoplastic stratified squamous epithelial lining.
Like dentigerous cysts, they are associated with impacted teeth; however, these tumors usually extend beyond the cemento-enamel junction and include the tooth root with variable calcification around the embedded tooth (Figure (7).
Mesiodens can cause a variety of complications, mainly when unerupted teeth affect the maxillary incisors, root resorption, axial rotation or displacement, diastema and dentigerous cyst formation.
Alterations of FHIT and P53 genes in keratocystic odontogenic tumor, dentigerous and radicular cyst.
The presence of mesiodens generally results in clinical and aesthetic problems, including failure to erupt, displacement of a permanent tooth, and dentigerous cyst formation and bilateral mesiodens has been found to result in significantly more problems than unilateral mesiodens, in previous studies.
Dentigerous cysts (DC) are benign odontogenic lesions caused by an alteration of reduced enamel epithelium which results in fluid accumulation either between the reduced enamel epithelium and the crown of an unerupted/impacted tooth or within the enamel organ itself.
In KOTs having some degree of inflammation, Stoelinga3 observed a loss of epithelial keratinization that resembled that seen in radicular, inflamed dentigerous, and paradental cysts.
