3- Dermoid cyst
4- Thyroglossal duct cyst - 18Cysts that are lateral to mid-line :1- Naso-labial cyst
2- Ranula - 19Cysts according to mode of growth that have balloon-like expansion :1- Radicular cyst
2- Dentigerous cyst - 20- The possible reasons for recurrence of Keratocyst :1- Pattern of growth is in antro-posterior direction.
2- Thin epith. lining is difficult to enucleate intact .
3-finger like cyst extension in cancellous bone.
4-stellate like cysts left behind after operation .
5- More rapid proliferation of lining epithelium ( increased mitotic index )
6- Other dental lamina remnants may produce another Keratocyst ( pseudo-recurrence )
7- budding of epithelium into C.T so this cyst grow by mitosis. - 21Cysts that have Mucous cells :1- Radicular apical
2- Dentigerous

2- Botryoid
3- Aneurysmal bone cyst ( sometimes ) - 24- Cysts that have 2 epithelia ( one of the oral cavity & one of the cyst ) :1- Eruption cyst
2- Gingival cyst of adult - 25Cysts that are counter-part of another cysts :1- Eruption cyst .. counter-part of Dentigerous cyst
2- Gingival cyst of adult .. counter-part of Lateral
periodontal cyst - 26Cysts that have Ectopia condition :1- Stafne's idiopathic bone cavity cyst
2- Thyroglossal duct cyst - 27- Aneurysmal bone cyst may occur on the top of bone diseases like :1- Fibrous dysplasia of bone
