TRANSCRIPT
DEFINITIONFOHALITOSISHalitosis is a term used to describe noticeably unpleasant odors exhaled in breathing.
It is estimated to be the third most frequent reason for seeking dental-aid, following tooth decay & periodontal diseases.
EpidemiologyExtremely common.
Majority of adult population have had it at some point in time.
Unpleasant condition which creates huge embarrassment with potentially grave consequences.
Formed by bacterial putrefaction of food debris, cells, saliva and blood. Proteolysis of proteins,peptides,amino acids,free thiol groups & volatile sulphides. Results from any form of sepsis : increased anaerobic activity of pathogens. Despite rigorous hygiene, good dentition, posterior dorsum of tongue is often a source.
Pathophysiology
Anaerobic Sulphur Producing Bacteria which normally live BELOW the surface of the tongue and in the throat(Fusobacterium,Actinomyces ,and Bacteriods forsythus) They assist humans in digestion by breaking down proteins found in specific foods,mucus or blood, and in diseased or “broken-down ”oral
tissue. Under certain conditions, these bacteria start
to break down proteins at a very high rate .
Proteins are made up of Amino Acids.Two ofAmino Acids in the mouth (Cysteine & methionine) are dense with sulphur.When “beneficial ”bacteria break down these compounds, the odorous and “lousy-tasting ”Volatile sulphur compounds (VSCs) are released ,Hydrogen sulphide, Dimethyl sulphide & methyl mercaptan) with other bad tasting compounds .
Compounds commonly produced by mouth bacteria and their odours :
Hydrogen sulfide- Rotten eggsMethyl mercaptan- FaecesSkatole - FaecesCadaverine - CorpsesPutrescine - Decaying meatIsovaleric acid - Sweaty feet
Pathophysiology of Halitosis
Etiology of Halitosis1. Oral & Throat Causes2. Nasal/ Nasopharyngeal problems3. Systemic disease4. Physiologic considerations5. Drugs6. Food7. Psychologic disorders
Oral & Throat Causes1 .Poor dental hygiene & food impaction2 .Dental & Gum diseases3 .Bacteria accumulation on the posterior dorsum oftongue & tonsils4 .Post nasal drip5 .Chronic tonsillitis &Tonsilloliths(Tonsil Stones)6 .Dry mouth7 .Oral sepsis8 .Oral Ulcerative lesions9 .Oral malignancy
Dental & Gum Disease Periodontal disease Dental caries Faulty restoration Denture Impacted or abscessed tooth Infected extraction sites Residual post-operative blood Debris under bridges or appliances kept in mouth at night or not cleaned properly.
Oral & Throat Causes
The real reason for the bad breath is bacteria that accumulate on back of tongue,in pockets of gum or in the throat.Anaerobic bacteria produce volatile sulphur compounds (VSC) such as methyl mercaptan & hydrogen sulphide.These VSC’s are source of malodor
Oral & Throat Causes
Tonsil Stones(tonsilloliths) are caused by an accumulation of sulfur-producing bacteria, post nasal drip, and debris that become lodged in the tonsil cryptsWhen this debris combines with the Volatile Sulfur Compounds produced by the anaerobic bacteria beneath the surface of the tongue, it can also create chronic Halitosis
Oral & Throat Causes
Breaking open one of
these white tonsilloliths, causes an absolutely terrible smell! which is actually a combination of volatile sulfur compounds,post nasal drip, and bacteria.
Oral & Throat Causes
Dry Mouth is a Leading Cause of Bad Breath Dry mouth is naturally occurring in elderly, most cases are caused by medications, adult beverages and mouthwashes with alcohol Saliva contains Oxygen, which helps oxygenate the mouth keep it healthy and fresh Dry mouth with less saliva and less oxygen, makes bad breath gets worse by creating an anaerobic environment, perfect for the bacteria to produce more of these odorous compounds.
Oral & Throat Causes
Excess Mucus (Post-Nasal Drip) is actually a Food Source For Anaerobic Bacteria When a person has post-nasal drip, mucus coats the back of the tongue and throat. Since mucus is made up of interlinked strands of protein, the bacteria, break down these proteins into odorous and sour tasting sulfur type compounds . Strong antihistamines don’t help, because the drying effect of the antihistamines also creates a problem (by reducing the amount of germ-controlling saliva)
Oral & Throat Causes
Patients with fissured tongue dorsum
may have elongated filiform papillaealong the fissure walls

Nasal/Nasopharyngeal problems1 .Sinusitis & Nasopharyngitis2 .Chronic nasal airway obstruction3 .Adenoid hypertrophy4 .Rhinolithiasis & Nasopharyngeal lithiasis5 .Nasal & Sinus granulomas6 . Nasal & Sinus tumors.7 .Nasopharyngeal Carcinoma
Systemic diseases Diabetes mellitus, Diabetic ketoacidosis, Renal failure, Bowel obstruction, etc. Liver failure Lung abscess, Bronchiectasis Severe GERD with H. Pylori Pharyngeal pouch Gastric & Esophageal carcinoma Carcinoma of the Larynx & Tracheobronchial Tree Granuloma of the Larynx & Tracheobronchial Tree Sjogren syndrome & Post irradiation therapy Trimethylaminuria
Physiologic considerations1. Reduction of
salivation2. Dehydration3. Vitamin deficiency4. Hunger5. Morning breath6. Aging7. Gastroesophageal
reflux8. Menstruation
Physiologic considerationsIt must be kept in mind that bad breath under the following circumstances is normal :
Morning breath because the function of salivary glands slows down over night and saliva thickens, which stops it from bathing mouth tissues properly, therefore mouth breathers face the problem more often, but it disappears when you eat or drink .
Hunger breath accompanies morning breath and arises from putrefaction of pancreatic juice, which pours into the stomach when nothing is eaten or drunk. Hunger breath is more apparent even after brushing, if morning meals are omitted .
Menstrual breath is caused because of hormonal disturbances, which trigger sloughing of the body’s lining tissues and oral tissues and creates more ridges for bacteria, leading to halitosis
Drugs1. Antihistamines2. Anticholinergics3. Antihypertensives4. Anorectics5. Antidepressants6. Antiparkinson7. Diuretics8. Sulfa drugs9. Long term use of antibiotics
Foods1 .Food eaten (onions, garlic, cabbage, etc)2 .High protein diet likeFish,red meat3 .Dairy food4 .Acidic food5 .Sugars6 .Coffee7 .Tobacco8 .Alcohol
Dense Protein Foods:
A high protein diet is always ideal for anaerobic bacteria,e.g. Fish, eggs,red meat
The end result is a buildup of amino acids, which are easily converted into volatile sulfur compounds by the anaerobic bacteria found within the surface of your tongue and throat.
Sugars:
Sugar, which are fuel for the bacteria to reproduce and create more sulfur compounds. In addition, other bacteria can take the sugars and produce glycan strands, which in turn end up causing thick layers of plaque on enamel and around gums. This leads to tooth decay and gum disease - and of course, worse breath
Acidic Foods :
Coffee - both decaf and regular contains high levels of acids.
Tea is a much better alternative.
Tomato Juice
All Citrus Juices - Orange Juice, Pineapple Juice, Grapefruit Juice
Acidic Foods :
The reason why acidic foods are a concern has to do with the way the bacteria react to an acidic environment .
The oral cavity has a normal pH of 6.5which is in the acidic range.
Acids make the bacteria reproduce much faster.
Onions and garlic already contain powerful volatile sulphur compounds, called mercaptans-eating them simply adds more odor-which can sometimes enter the lungs and bloodstream.
Milk and other dairy products may cause problems for most people (The fat content does not matter, so low fat milk is just as problematic as butter)
In lactose intolerance, the system cannot digest these dairy products properly,so they are available to the bacteria for an extended period of time.
Trimethylaminuria-TMA“ Fish Odour Syndrome” A rare problem occurs in people who have an inability to breakdown certain proteins found in beans.The odour produced is similar to decaying fish .
The odor consists of sulfur compounds & nitrogen compounds (amines) People with this condition must abstain from beans and other dense protein foods.
Smoking (nicotine) Smoking has a drying effect on oral tissues Destroys ascorbic acid (vitamin C) which is essential for immunity Odor associated with smoking depends on a number of factors, directly related to the tar, nicotine, and other foul smelling substances that accumulates on teeth and soft oral tissues (tongue, cheeks, gums)There is no effective way to totally eliminate smoker's breath, although oral hygiene can help to minimize it .
DIAGNOSIS1. Oral examination2. History taking3. Smelling4. Sampling by spoon, gauze, cotton5. Information from family, friend6. Self examination7. Use of the halimeter
EXAMINATION Some of the characteristic smells accompanied by various diseases include acetone (a fruity smell)caused by diabetic ketoacidosis. Sweaty smell caused by liver dysfunction and extremely foul smell caused by diphtheria.
INVESTIGATIONS
Halimeter Level of intra oral Volatile
Sulphur Compounds can be estimated using portable sulphide monitors.Concentration of VSC’s
correlate well with level of malodour reported by observers.
Management Identify & eliminate obvious causes Dental & Oral hygiene Dietary advice
Neti pot is an instrument used for
irrigation of nasal passages
Laser Tonsillectomy or tonsillectomy Adenoidectomy
Neti pot
ManagementDental & Oral hygieneRegular Dental ConsultationRegular proper tooth brushingInterdental flossingTongue cleaning, brushing, scrapingTongue cleansing by tongue scrapper ,
gauze, tooth brush without pasteMouth rinses
Baking soda etsaphtoot or mouthwash. This changes the acidity of the mouthDenture care & soaking in antiseptic solution over night
Management The only effective method of treating Halitosis is by attacking the bacteria’s ability to produce VSC’s and by converting the VSC’s into non-odorous and non-tasting organic salts.
Nearly all cases of “real ”bad breath and/or
taste disorders (or Halitosis) involve good bacteria and should never be treated with antibiotics.
Dietary advice
Avoid odiferous foods: Onion, Garlic, SpicesAvoid habits: Smoking, Alcohol, CoffeeTake regular meals, fresh fruits
Eat fresh, fibrous vegetables such as carrots
Drink tea regularly: aet ni slonehpyloPhtworg lairetcab tibihniDo not drink too much coffee
ManagementDietary advice
Don't miss breakfast. Hunger lead to killing-breath .
Drink plenty of liquids/ 8 glasses of water a day .
Eat parsley or wintergreen with your main meals. These herbs release pleasant oils as they chew them which linger for hours .
Avoid fats - cheese, butter, milk, fat meats - in your diet if indigestion is the source of your bad breathAvoid beans &high protein diet in Trimethylaminuria
ManagementDietary advice
Stay away from candies, mints, and chewing gum if they contain sugar.
Chew sugar-free gum for a minute or two at a time, especially if your mouth feels dry, chewing parsley, mint, cloves or fennel seeds may also help.
In Xerostamia, increase your fluid intake( at least 18-20
glasses per day ) , suck on sugarless lozenges.
Citrus fruits, Vitamin C makes you resistant to coughs and colds
