DEVELOPMENTAL CONDITIONS
Developmental conditions are soft tissue or hard tissue defects that occur during the development of the individual, either before or after birth.

LIP PITS
- Depressions or concavities seen on lip
- Seen with Van Der Wood syndrome along with cleft lip

FORDYCES GRANULES
- Ectopic sebaceous glands
- On buccal mucosa
- Usually seen as Bilaterally symmetrical

LEUKOEDEMA
- White or whitish grey edematous (fluid) lesion of buccal mucosa
- It dissssipiates when cheek is stretched

ANGIOMAS
- ANGIO - VESSELA OMA - TUMOR
- TUMORS composed of blood vessels or lymph vesseLs
- A salivary gland tumor that mestasises to bone

CENTRAL HEMANGIOMA – IV
- Commonly in upper lip
- There is congenital focal proliferation of capillaries
- Absolute contradiction – extraction of a tooth**
- Multilocular radiolucency lesion
- Associated syndrome – Struge Weber Syndrome
- Port wein steins + calcification of duramatter
- Strawberry appearance of skin – capillary hemangioma
Other variants
- Strawberry appearance of gingiva – warners granulomatosum
- Strawberry appearance of tongue (white coated tongue with red inflamed fungiform papilla)– scarlet fever (bacterial infection)
- Raspberry appearance of plate – papillary hyperplasia(denture)

LYMPHANGIOMA

CONGENITAL FOCAL PROLIFERATION OF LYMPH VESSELS
-Oral lymphangiomas are very rare
- appear as purple spots on tongue


DEVELOPMENTAL SOFT TISSUE CYST - DERMOID CYST
- Mass in the midline of the body – intraoral or extra oral
- Intraorally – floor of the mouth if above mylohyoid
- Mass will be seen in the upper neck if it forms below the mylohyoid
- Contains hair, sebaceous glands etc – doughy consistency

BRANCHIAL CYST
- Lateral neck cyst
- Epithelial cyst within lymph node of neck

PSEUDOCYSTS OF JAW

STAFNE / STATIC BONE CYST
- Radiolucency in the post mandible below the mandibular canal
- Its is not a cyst- just a picture caused due to lingual concavity of the jaw, ie. An invagination in the lingual surface of the jaw - just variation of normal anatomy.

NASOPALATINE / MEDIAN PALATINE / Incisive canal cyst CYST
- Seen b/w roots of Central incisors
- R/F - Divergence of roots
- The nasopalatine cyst appears as a well-defined, round radiolucency in the midline of the anterior maxilla
- Sometimes it appears to be ‘heart-shaped’ because of superimposition of the anterior nasal spine.
- Radiological assessment should include examination of the lamina dura of the central incisors (to exclude a radicular cyst) and assessment of size (the nasopalatine foramen may reach a width of as much as 10 mm).

- Qn. Pt. came to the clinic complaining from pain related to swelling on maxillary central incisor area with vital (under percussion) - nasopalatine cyst
- Qn. 40-60y, Male, in maxilla in the midline between the roots of upper central incisors which are vital.
- Intra-osseous lesion is well circumscribed rounded or Heart-shape RL. area (due to superimposition of nasal spine)

GLOBULOMAXILLARY CYST
- Seen between Lateral incisor and Canine
- Inverted pear shape
- Variant of OKC or lateral periodontal cyst
- Vital tooth bilateral

SOLITARY BONE CYST – Haemorrhagic /Simple / Traumatic bone cyst
- A pseudocyst- ie. No epithelial lining
- Kids doing sports- injury
- R/F – scalloped border around teeth***
- Treatment is curettage and closure
