 ODONTOGENIC CYST OF THE ORAL AND MAXILLOFACIAL REGIONS

DEFINITION OF CYST:( kramer in 1947)

Pathological cavity having fluid,semifluid or gaseous contents and which is not created by the accumulation of pus ,Its frequently ,but not always lined by epithelium .

  • True cyst : Is a cyst with epithelial lining
  • Pseudocyst:Cyst without epithelial lining 

CLASSIFICATION OF ODONTOGENIC CYSTS OF THE ORAL AND MAXILLOFACIAL REGION

Shear in 2007 classified cyst of the oral and maxillofacial region as :
A) CYST OF THE JAW:
                                    CYST OF THE JAW
EPITHELIUM LINED CYST        
 1)DEVELOPMENT ORIGIN        2 INFLAMMATORY ORIGIN

1 A)ODONTOGENIC CYSTB)NONODONTOGENIC CYST
Gingival cyst of infant                Nasolabial cyst
Dentigerous cyst                       Midpalatal raphe cyst of infants 
Calcifying odontogenic cyst
Lateral periodontal cyst
Eruption cyst
Glandular odontogenic cyst
Odontogenic keratocyst

2) INFLAMMATORY ORIGIN
Paradental cyst and juvenile paradental cyst
Collateral cyst
Radicular cyst ,apical and lateral

 CYST OF JAW 
NON -EPITHELIAL LINED CYST
Aneurysmal bone cyst
Solitary bone cyst
B)CYST ASSOCIATED WITH MAXILLARY ANTRUM
Mucocele
Retention cyst
Pseudocyst
C)CYST OF THE SOFT TISSUES OF THE MOUTH ,FACE,NECK:
Anterior median lingual cyst
Thyroglossal duct cyst
Branchial cyst
Dermoid and epidermoid cyst
Oral cyst with gastric or intestinal epithelium 
Cystic hygroma 


MNEMONICS :

YES ,to remember all at once is difficult dont worry when stencident is here ,all you have to remember is this sequence of event that I will be listing out now :
 TO REMEMBER CYST OF JAW
  • Narendra Modi visited GDC to attend LEGO competition ,AS per his request all took PCR Test for corona.
CYST ASSOCIATED WITH MAXILLARY ANTRUM
  • Winners received MRP.stethoscope

CYST OF THE SOFT TISSUE OF THE MOUTH,FACE,NECK)
  • At vote of thanks ceremony ,he wished " All The Best DOCtors"
VISUAL MNEMONICS:

TO REMEMBER CYST OF JAW








TO REMEMBER CYST ASSOCIATED WITH MAXILLARY ANTRUM:


Mucocele
Retention cyst
Pseudocyst 



CYST OF THE SOFT TISSUE OF THE MOUTH,FACE,AND NECK

ALL THE BEST DOCTORS 

Note : The use of same mnemonic and sequential events if posted in any other website and youtube channel is strictly prohibited since all rights are reserved only  to stencildent.

AIM OF THIS POST :
Today we started with definition of a cyst,then shear classification of odontogenic cyst ,since to remember all at once is difficult, I have created a sequence of events and key words as mnemonic ,have spent more time in creating this and making it much simpler if you like it and if it helped you then do let me know in the comment section below as it would be really motivating for me.

At stencildent we are celebrating this week as #classification week
Day -3  classification of odontogenic cyst ,this  topic was suggested by our very own stencildent family member lakshmi Priya.A.
To suggest us topics and to get notifications from our latest post do get contacted through instagram as well.

HELLO! DOCTOR VANAKAM, I hope you all are doing good today we will be discussing sterilization various methods of sterilization, about dry heat sterilization and moist heat sterilization along with different methods employed, and what are the materials to be placed in this method in detail about autoclave its principle, working and of course uses. As I have had already informed you all through my previous post on the contribution of Louis Pasteur and Koch postulates if we haven't checked it out yet do check it out using this link   https://www.stencildent.com/2020/07/contributions-of-louis-pasteur-and-koch.html  wherein I would explain the importance for the need of the HOUR and always to sterilize things to and from the patients and also get geared up for the next post on SHOCK wherein I would cover the definition, types, classification along with etiology, pathogenesis, flow chart, the complication of septic shock in detail so now without any further ado lets get started.

CONTENTS: 1)Definition 2)Classification 3)type 1 hypersensitivity reaction a)1st exposure b)2nd exposure c)mediators of reaction d)late-phase reaction 4)type 4 hypersensitivity 5)treatment  1)DEFINITION: It refers to a condition in which immune response results in excessive reaction leading to tissue damage, disease, or even death in a sensitised host. 2) CLASSIFICATION: Coomb and gel classification in 1963 into type 1 to 4  Type 1,    type 2, type 3       : They depend on the interaction of antigen with humoral antibodies They are the immediate-type reaction  type 4 : They are mediated by t lymphocyte Delayed-type of hypersensitive reaction 3)TYPE 1
