Breaking The Block: A deep Dive Into Salivary Gland Stones

-

 SIALOLITHIASIS /SALIVARY CALCULI /SALIVARY STONE 

  • Calcified structure that develop within salivary ductal system 
  • Arise :deposition of calcium salt around a nidus within the duct 
  • Debris :Bacteria +Epithelial cells + Mucous +foreign body 
  • Not related to any system derangement in calcium, phosphate metabolism 

COMPOSITION:

  • Hydroxyapatite crystal
  • Calcium
  • Phosphorous 
  • Magnesium
  • Potassium chloride
  • Ammonium





ETIOLOGY:

  • Exact -unknown

CLINICAL FETAURE:

  • AGE: No gender predilection
  • Site: Submandibular salivary gland duct ,parotid, minor salivary gland






CLINICAL PRESENTATION:

  • Acute painful ,intermediate swelling of affected gland especially at meal time
  • Pain-size, degree of obstruction ,amount of resultant back pressure produced within the gland 
  • While eating -increased salivary flow -stone blockage causes pooling of saliva within the duct and gland 
  • Salivary gland encapsulated allows only little expansion this enlargement result in pain
  • Size:2mm to submandibular salivary gland 







Why is it seen in submandibular gland more commonly?

  • Submandibular excretory gland duct is wider in diameter ,longer than Stenson duct 
  • Salivary flow in submandibular gland is against gravity 
  • Submandibular gland salivary secretion is more alkaline compared with pH of parotid gland 
  • Submandibular gland saliva contain increased quantity of mucin protein where as parotid saliva is entirely serous 
  • Calcium ,phosphate content in submandibular gland saliva is greater than in other gland 








INVESTIGATION;

  • Occlusal radiograph
  • Radiograph mass (3mm in diameter )
  • If parotid gland involved then puffed cheek view in PA view to be taken 







COMPLICATION:

  • Xerostomia
  • Sialadenitis

TREATMENT:

  • Small-stimulate salivary flow ,milking of gland towards ductal orifices' 
  • Gentle message
  • Pilocarpine 
  • Larger: surgical
  • lithotripsy 
  • Sialoendocsopy

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 starte...

                          HYPERSENSITIVITY   hello, doctor vanakam, I hope you all are doing good, as intimated through the last post on anaerobic culture method  https://www.stencildent.com/2020/08/anaerobic-culture-methods-microbiology.html  if u haven't checked it out do read using this link 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 i...
