 Hello everyone welcome back to another session in the industry and more today's session is about cherubism it is one of the non-inflammatory disease which involves jaw. So we have learnt fibrous dysplasia, osteogenesis imperfecta, Pajet disease, Kredo-cranial dysplasia or Down syndrome so all these are involving the facial bones. So similarly cherubism also is a non-inflammatory condition which affects the jaw. So let us learn about cherubism, its features, differential diagnosis and oral manifestation. Cherubism is a autosomal dominant disease which is most commonly seen in children than adults and the male groups are more affected than the girls. And the most common thing is the jaw is very broad and protruding and both maxilla and mandible will be affected but there will be a symmetry of the involvement of this lesions. So the lesions are like there will be the replacement so the maxilla and mandible are enlarged as this bone is replaced by painless cyst like growth. So maxilla and mandible the bone will be resolved and there will be presence of painless cyst like growths so there will be a symmetrical expansion of maxilla and mandible. That is why this peculiar name has got chabicic appearance so that is cherubism. So the person looks like a chabicic appearance how we see our baby appearance like the cheeks are very broad so such appearance is a common feature of cherubism. The feature is there is increased alkaline phosphatase so it has seen in most of the non-inflammatory diseases of bone. In radiographic feature there will be long and tubular bones and this radiolucine lesion the radiolucine lesion which in the diaphysis and metaphysis with sclerotic border which is known as red sign. So that is a striking feature of cherubism red sign there will be a sclerotic border and the radiolucine lesion with sclerotic border. The frontal bone is more commonly involved than the sphenoid bone and it could be single or multiple lesions there will be mixed radiolucine and radiopic the radiographic appearance and the skull view it looks like ground glass pebbled or orange peel appearance. So in oral manifestation there will be expansion and deformity of jaw and the eruption pattern will be different and there will be loss of normal support of this developing teeth and there will be a delayed eruption. Delayed eruption is due to the endocrine disturbances and the maxilla and mandible are enlarged and this replaced by the painless cyst that is where it is looks like a chubby cheek appearance. So differential agnosis, endocondroma, non ossifying fibroma, giant cell tumor, hyperparathyroidism and its management and surgical part if it is very much deforming we should go for surgery and we can think about the bone grafts and otherwise it is not very much indicated for surgery. So that is about the chubby cheek appearance it is a autosomal dominant pattern commonly seen in children and specially in boys. So it is nothing but a expansion of the maxilla and mandible by the cyst like growth within these bones maxilla and mandible the bones will be replaced by the cyst like growth and the unique feature is a red sign ground glass piblet or orange peel appearance. So I will come up with a new topic in dentistry and more thank you.
