Xerostomia The subjective feeling of oral dryness, associated with: AA change in saliva composition RReduced salivary flow NNo identifiable cause
It is NOT a disease, but a symptom of various medical conditions, or a side effect of radiation or a medication.
Xerostomia You can do some things to relieve dry mouth temporarily, but the best long term dry mouth remedy needs to address the cause. For many people, however, little can be done to alter the underlying cause of dry mouth.
Diagnosing Xerostomia Sialometry – salivary flow measurement assessment - Clinical setting, done by a dentist Complaint of dry mouth / frequent water intake - Especially at night Difficulty eating dry foods like crackers or toast Tongue Depressor Test Lipstick sign
Diagnosing Xerostomia Saliva is stringy, ropey, foamy, or absent Tongue clicks during speech Dental decay present along the gum line of several teeth
Complications Associated with Dry Mouth Difficulties in tasting chewing swallowing speaking Burning feeling in mouth Dry throat, hoarseness Cracked lips (chelitis)
Complications Associated with Dry Mouth Painful, rough, dry tongue (glossodynia) Mouth sores Mouth infections Oral candidiasis is one of the most common oral infections seen in xerostomic patients Poor nutrition intake Increase risk of dental decay (caries) Increased risk of gum disease (periodontitis)
What’s Up With SALIVA? Helps digest food Ptyalin and Amylase = digestive enzymes Antimicrobial Helps control mouth pH Mechanical cleansing action Tooth remineralization Lubricates the oral cavity (taste chew swallow speak) Helps retain dentures These help decrease Tooth Decay.
Cariogenic Foods Foods that promote formation of dental decay Fermentable carbohydrates, those that can be broken down by salivary amylase and ptyalin Result in lower mouth pH Include crackers, chips, pretzels, cereals, breads, fruits, sugars, sweets, desserts
Cariostatic Foods Foods that do not contribute to decay Do not cause a drop in salivary pH Includes protein foods, eggs, fish, meat and poultry; most vegetables, fats, sugarless gums
Anticariogenic Foods Prevent plaque from recognizing an acidogenic food when it is eaten first May increase salivation or have antimicrobial activity Includes xylitol (sweetener in sugarless gum) and cheeses
Other Factors that Affect Diet Carogenicity Consistency: Liquids are cleared quickly while sticky foods remain on the teeth Meal frequency: frequent meals and snacks increase duration of exposure Food form: liquid, solid, slowly dissolving Sequence of eating: cheese or milk at the end of the meal decrease the likelihood of decay
The amount of sugar consumed is not as important as the eating behavior: Frequency = Risk Stickiness = Risk Consumed between meals = Risk Factors affectingTOOTH DECAY
