Describe oral health education topics and application instructions for RAS.
- The cause of it is unknown, but the primary goal in the management of it is to identify and eliminate or manage contributory factors which may include:
- local factors: trauma, tooth paste allergy
- nutritional deficiencies
- absorptive disorders
- food allergies
- other systemic conditions manifesting ulcerations
Describe oral health education topics and application instructions for OLP
- Cause is unknown, but it is believed to be an autoimmune disease with a genetic predisposition

- there is a possible association with OLP and oral squamous cell carcinoma
Describe oral health education topics and application instructions for oral EM
- The disease can be minor, major, or potentially fatal (stevens-johnson syndrome) and toxic epidermal necrolysis
- Most cases are related to infections, especially HSV
- but most cases of SJS and TEN are related to pharmacologic agents
- It has been reported to develop after immunizations or radiotherapy
- If EM is related to a drug, pt should never take that drug, or any other drug with crossreaction potential
- the disease often recurs, so pts should be warned, and to seek medical attention right away if it does
Describe oral health education topics and application instructions for oral CP
- The mean age of onset of this disease is 62 years, and appears to have a 2:1 predilection for women
- Oral mucosal lesions usually heal without scarring, but if they do scar, it is a result of submucosal fibrosis, which is a key feature of disease progression in other sites such as the conjunctiva of the eye, and the larynx

Oral Lichen Planus
Differentiate between the clinical appearance of herpes labialis and intraoral recurrent herpetic infection.
- herpes labialis: focal vesicular lesions affecting the lip vermilion or other perioral sites such as the skin or ala of the nose, the vesicles rapidly rupture and crust
- intraoral recurrent herpetic infection: small clusters of pinpoint ulcers, usually restricted to the keratinized mucosa
Differentiate between treatments for primary versus recurrent herpetic infections.
- Primary herpetic infection: strategies are targeted to ensure adequate hydration and nutrition to provide palliation; topical anesthetic agent (diphenhydramine hydrochloride [children's benadryl]) or lidocaine viscous, and if necessary a systemic analgesic
- recurrent herpetic lesions: These lesions are self-limiting and often require no treatment; OTC topical agents are available to help, docosanol (Abreva) is the only OTC formulation specifically approved by the FDA for tx of RHL. Penciclovir (Denavir), acyclovir (Zovirax) creams are used
How efficacious are preparations for treating recurrent HSV infection?
- They are most effective when initiated during the prodromal phase
- these lesions often don't require treatment
- the medications will not have a significant effect
Describe oral health instructions related to the presence of RHL and warnings when topical anesthetic agents are recommended for recurrent herpetic lesions.
- All pts should avoid touching the lesion and practice good hygiene (wash hands) to reduce the risk of autoinoculation
- topical anesthetics are recommended for pts who manifest frequent recurrent episodes, or who otherwise desire antiviral therapy
- Also, for pts whom sunlight precipitates an outbreak, SPF 15 or higher lip balm is recommended
List products for the tx of herpetic lesions, and describe instructions for their use.
- primary herpetic infection:
- diphenhydramine hydrochloride (benadryl) or lidocaine viscous: be careful of self-induced injury or interference with swallowing
- aceta minophen, and in rare instances acetaminophen/codeine: avoid aspirin in children
- docosanol (Abreva) cream: applied at first prodromal sign, reapplied 5 x's a day until lesion is healed
- penciclovir (denavir): apply every 2 hrs until lesion is healed
- acyclovir (zovirax): cream applied 5 x's a day until lesion is healed
- valacyclovir (valtrex) oral antiviral: 1-day therapy, take 2 tablets taken twice daily (2 tabs bid for 1 day)
List products for candida infection and describe pt instruction for their use

- Clotrimazole troche: dissolved slowly in the mouth, 5 times a day for 14 days
- Ketoconazole cream: applied to affected area once a day for 2-4 weeks
- Systemic oral antifungal agents are available for pts who are unresponsive to topical therapy: detoconazole, fluconazole, itraconazole
- fluconoazole is drug of choice
- itraconazole is reserved for treatment if it resists fluconazole
Describe clinical signs of xerostomia.
- noticeable lack of wetness to the mucosal tissues and teeth
- saliva that is thick and ropey
- absence of saliva pooling in the floor of the mouth
- red, dry, and atrophic mucosa

Describe management of pericoronitis
- Step 1: drainage established by a curet or periodontal probe under the operculum
- next, irrigation: with saline or antiseptic rinse; may be followed by inserting a wick of iodoform gauze; pt is to rinse w/ warm salt water for 2 mins every waking hour
- extract tooth: if opposing tooth is traumatizing operculum, opposing tooth extracted or underto odontoplasty; but make sure the infection is managed
- antimicrobial regimen prescribed: if pts manifests systemic signs of infection, and also following debridement to remove exudate (penicillin is initial drug of choice) if pen VK doesn't work, give them metronidazole (it is beta-lactamase resistant)
