Presentation 8 kidane

  1. 1. By Kidane HailemichaelPRESENTATION 8
  2. 2. DIGESTIVE SYSTEM TERMS Bite-wing x-ray Lavage Extraction Anastomosis
  3. 3. BITE-WING X-RAY The bite wing x-ray is taken to visualize the crown of the posterior teeth and the height of the areolar bone in relation to the cementoenamel junction, which are the demarcation lines on the teeth which separates tooth crown from tooth root
  4. 4. BITE-WING X-RAY Biting x-rays are extremely helpful in determining;  Tooth decay located in between teeth  Various stages of gum disease  Problems with tooth alignment  Detecting a buildup of dental tartar  Measure bone loss due to advanced periodontal disease
  5. 5. PROCEDURE The film resembles a “ T shape” that’s placed on the anterior side of the jaw The film extends to cover both the upper and lower teeth, and the patient bites a tab in the middle to hold the film in place After the dental hygienist positions the biting in the mouth , the patient closes his or her teeth to secure the film An x-ray camera is then used to photograph several teeth at once
  6. 6. ADVANTAGES OF BITE-WING X-RAYS Once an initial full set of x-rays are taken, bitewings are used during interval checkups to look for changes in the teeth and gums It keeps the patient from having to sit through a complete set of x-rays every six months, saving the patient time and money in the long run Taking a bitewing is a quick and painless process, and the film is usually ready for the dentist to view in just a few minutes
  7. 7. PRECAUTIONS Level of radiation patients encounter is not significantly enough to cause a health concern. Regardless, no matter how many bitewings are taken, patients should always be covered with a lead apron.
  8. 8. LAVAGE Lavage is the irrigation or washing out of an organ Gastric lavage, also commonly called stomach pumping or gastric irrigation, is the process of cleaning out the contents of the stomach
  9. 9. LAVAGE Has been used over 200 years as a means of eliminating poison from the stomach Is used on a person who has ingested a poison or overdose on a drug such as alcohol May be used before surgery, to clean the contents of the digestive tract before it is opened
  10. 10. TECHNIQUE Gastric lavage involves the passage of tube via the mouth or nose down into the stomach followed by sequential administration and removal of small volumes of liquid The placement of the tube in the stomach must be confirmed by:  Air insufflation while listening to the stomach  pH testing a small amount of aspirated stomach content  X-ray  This is to confirm the tube is not in the lungs
  11. 11. PRECAUTIONS Patients who are unconscious or can not protect their airways should be intubated before performing lavage Patient must be put to sleep for a period of time during the operation due to its high risk of shock and hypernatremia
  12. 12. EXTRACTION Extraction is the removal of tooth from the mouth Extractions are performed for a wide variety of reasons , including tooth decay that has destroyed enough tooth structure to render the tooth non- restorable
  13. 13. REASONS FOR TOOTH EXTRACTION Severe tooth decay and infection Extra teeth which are blocking other teeth from coming in Severe gum disease which may affect supporting tissues and bone structure of teeth In preparation for orthodontic ( braces) Teeth in the fracture line Fractured teeth Supernumerary, supplementary or malformed teeth Tooth of poor appearance, unsuitable for restoration
  14. 14. TYPES OF EXTRACTION Simple Extractions- are performed on:  teeth that are visible in the mouth  usually under local anesthetic  require only the use of instrument to elevate and grasp the visible portion of the tooth Surgical extraction- Involves the removal of the teeth that can not be easily accessed, either they have broken under the gum line or they have not erupted fully
  15. 15. ANASTOMOSIS An anastomosis is a surgical connection between two structures. It usually means a connection that is created between tubular structures , such as blood vessels or loops of intestine Surgical anastomosis means to join together two hollow organs, usually to restore continuity after resection, or by pass an unresectable disease process
  16. 16. ANASTOMOSIS Historically such procedures were performed with suture material, but increasingly mechanical staplers and biological glues are employed Anastomosis may be:  End- to - end  Side- to - side  Side- to – end  Depending on the circumstance of the required reconstruction or bypass
  17. 17. ANASTOMOSIS ARE PERFORMED ON Gastrointestinal (GI) tract-  Esophagus  Stomach  Small bowel  Large bowel  Bile duct  Pancreas Anastomosis are also performed on blood vessels and urinary tract
