3What is an ulcer?A mouth or oral ulcer is an open sore in the mouth, or rarely a break in the mucous membrane or the epithelium on the lips or surrounding the mouth.
4Epidemiology and frequency Mouth ulcer is a very common oral lesion. Epidemiological studies show an average prevalence between 15% and 30%. Mouth ulcers tend to be more common in women and those under 45. The frequency of mouth ulcers varies from fewer than 4 episodes per year (85% of all cases) to more than one episode per month (10% of all cases) including people suffering from continuous recurrent aphthous stomatitis
5What cause ulcers? Trauma (physical injuries) Chemical injuries SmokingInfection- viral- bacterial- fungal- protozoansImmunodeficiencyAutoimmunityAllergyDietary
6Tools for diagnosis: History Examination Further investigation Additional diagnostic methods – biopsy
7Further investigation – questions you should ask: How long have you had that ulcer?How many ulcers do you have?Is it painful?Can you relate them to any trauma, hot food or another factors?Is it the first time or you had them before?Where are they located in the mouth?Do they start as ulcer or as vesicle/bulla?Do you get them anywhere else on the body?

9Things you need to look for: SiteNumberSizeShapeBaseEdge
10Differential diagnostic, based on history How long have you had the ulcer?Long time – chronicChronic trauma (single, can identify the cause, and should improve after removal)Malignancy (single, painless)TB (single ulcer in the tongue/palate, associated symptoms – chronic cough)Mucous membrane pemphigoid (multiple ulcers affect mainly gingiva, blood filled blisters)Primary or tetriary syphilis
11Recent – acuteAcute trauma (single, can identify the cause, and should improve after removal)Viral infection (multiple, associated symptoms – fever)Immune mediated disease (Erythema multiforme, RAS)
12How many ulcers do you have? SingleTraumaticPrimary or tetriary syphilisTBMalignancyMultipleViral infectionImmune mediated disease
13Is it painful? Yes Acute causes (trauma, viral, immune mediate) No Chronic causes (trauma, TB)
14Can you relate them to trauma or hot food? YesConfirm traumatic ulcerRemove the causeReview after 1 weekNoLook for other causes
15Do you get them anywhere else on the body? NoThink or oral conditionsYes – where?Skin – mucocutanous disease (lichen planus, pemphigus)
16Traumatic lesions Mechanical trauma (acute or chronic) Chemical injury (acid, alcali)Physical injury (thermal injury, electrical injury)
22Clinical features of traumatic ulcers: •They are clinically diverse, but usually appear as a single, painful ulcer with a smooth red or whitish-yellow surface and a thin erythematous halo.•They are usually soft on palpation, and heal without scarring within 6–10 days, spontaneously or after removal of the cause.•However, chronic traumatic ulcers may clinically mimic a carcinoma.•The tongue, lip, and buccal mucosa are the sites of predilection.•The diagnosis is based on the history and clinical features.•However, if an ulcer persists over 10–12 days a biopsy must be taken to rule out cancer.
23Treatment Removing factors, caused trauma Good hygiene of oral cavity Antiseptic for 7-10 daysAnalgetics if it is necessaryTopical steroids may be used for a short time.Biopsy
24LeukoplakiaEtiology: -trauma from habitual biting, dental appliances -tobacco use -alcohol consumption -oral sepsis -local irritation -syphilis -vitamin deficiency -endocrine disturbances -dental galvanism -actinic radiation (in the case of lip involvement).Symptoms - painless, fuzzy white patches on the side of the tongue or cheeks.
25Clinic-located on the tongue, mandibular alveolar ridge and buccal mucosa in ~50%. -palate, maxillary alveolar ridge, lower lip, floor of the mouth and the retromolar regions are somewhat less frequently involved. -may vary from nonpalpable, faintly translucent white areas to thick, fissured, papillomatous, indurated lesions. -surface is often wrinkled or shriveled in appearance and may feel rough on palpation. -color may be white, gray, yellowish-white, or even brownish-gray in patients with heavy tobacco use. Physical: -lesion cannot be wiped away with a gauze
27Differential diagnosis: Candidiasis and aspirin burn - can be wiped away with a gauzeErythroplakia (a red plaque that does not rub off), is a dysplastic lesion (or worse) in 90 percent of cases.
28TreatmentTreat dental causes such as rough teeth, irregular denture surface, or fillings as soon as possible.Stopping tobacco or/and alcohol.Removal of leukoplakic patches with using a scalpel, a laser or an extremely cold probe that freezes and destroys cancer cells (cryoprobe).
29Chemical injures: Chemicals such as aspirin or alcohol that are held or that come in contact with the oral mucosa may cause tissues to become necrotic and slough off creating an ulcerated surface.
30Treatment: Wash a mouth with lot of water Analgetics (for 3-5 days ) Antiseptics ( for 7 – 10 days)Keratolytics (after 5-7 days)Keratoplastics (after 7-10 days)
31Physical injures:Electric Burns to the Mouth -are most commonly caused when a child bites into a cord, touches the male ends of a "live" but improperly connected cord, or sucks on the female end of an extension cord that is plugged into the wall. The vast majority of the patients is younger than three years.
32Treatment: Conservative Antiseptics Antibiotics Analgetic 2. Surgical (after the healing was completed and after the degree of functional and/or aesthetic deformity was established (usually 6 months post-injury)).
33Stomatitis Description Stomatitis is an inflammation of the lining of any of the soft-tissue structures of the mouth. Stomatitis is usually a painful condition, associated with redness, swelling, and occasional bleeding from the affected area. Bad breath (halitosis) may also accompany the condition. Stomatitis affects all age groups, from the infant to the elderly.DefinitionInflammation of the mucous lining of any of the structures in the mouth, which may involve the cheeks, gums, tongue, lips, and roof or floor of the mouth. The word "stomatitis" literally means inflammation of the mouth. The inflammation can be caused by conditions in the mouth itself, such as poor oral hygiene, poorly fitted dentures, or from mouth burns from hot food or drinks, or by conditions that affect the entire body, such as medications, allergic reactions, or infections.
34Herpetic stomatitisHerpetic stomatitis is a viral infection of the mouth that causes ulcers and inflammation. These mouth ulcers are not the same as canker sores, which are caused by a different virus.
35Symptoms:Blisters in the mouth, often on the tongue, cheeks, palate, gums, and a border between the lip (red colored) and the normal skin next to itDecrease in food intake, even if the patient is hungryDifficulty swallowing (dysphagia)DroolingFever (often as high as 104 °Fahrenheit) may occur days before blisters and ulcers appearIrritabilityPain in mouthSwollen gumsUlcers in the mouth, often on the tongue or cheeks -- these form after the blisters pop
36CausesHerpetic stomatitis is a contagious viral illness caused by Herpes virus hominis (also herpes simplex virus, HSV). It is seen mainly in young children. This condition is probably a child's first exposure to the herpes virus.An adult member of the family may have a cold sore at the time the child develops herpetic stomatitis. More likely, no source for the infection will be discovered.
37Differential diagnostics: Streptococcal pharyngitis –does not involve the lips or perioral tissues and vesicles do not precede the ulcersErythema multiforme – ulcers are larger, usually without a vesicular stage and are less likely to affect the gingiva.Aphthous stomatitis – the multiply lesions, palatal and gingival location are indicative to herpesvirus infection. Additionally, aphthae usually localized only on nonceratinized mucoza, such as the floor of the mouth, alveolar mucosa and buccal mucosae.
38Treatment: Good oral hygiene Acyclovir family of antiviral medications – non later than 48 hours!Analgetic ( or oral topical anesthetic )Diet (no hot or pepper food)Antiseptics
39Aphthous UlcersOf all the type of nontraumatic ulcaration that affect oral mucosa that is the most common.
40Aphthous ulcers are also known as canker sores Aphthous ulcers are also known as canker sores. They are painful, temporary sores that may occur anywhere in the mouth. Usually, they show up in several places:On the inside of the lipsInside the cheeksOn the tongueAt the base of the gums
42Etiology: Immune system disorders Other conditions cause similar sores:Blood and immune system diseases, including HIVVitamin and mineral deficienciesAllergiesTraumaCrohn's diseaseLupus
43Clinical features:Three forms of aphthous ulcers have been recognized: minor, major and herpetiform.
44§ Major Ulcerations (> 0,5cm)—10% of lesions o extremely painful (odynophagia)... typically heal with scar formationo Appearance- deeply cratered ulcerso Duration- > 1 month for healing.o Location- posterior oral cavity.0 Number – 1- 10o NOTE- THINK OF HIV DISEASE PROGRESSION OR IMMUNOSUPPRESION§ Minor Ulceration (1-5 mm)—85% of lesionso painful… heal without scar formationo Duration dayso Location- anterior oral cavity0 Number – 1-5§ Herpetiform Ulceration (1-3mm lesions that form clusters)—5% of lesions.o Sxs- as above (but more severe)0 Number –o Locational – any intraoral site
45Minor ulcers: Are the most commonly encountered form Single, painful oval ulcer less than 0,6 mm, covered by a yellow fibrinous membraneLast 7 to 10 daysPeriods of freedom from disease – 2-3 weeks to year
46Major ulcers: Lesions are larger: more than 10 mm More painful Persist longer that minor aphthaeOne ulcer disappears, another one startsHealing generally occurs in 6 weeks and longerChronic stress, common disease can cause
47Herpetiform ulcers Recurrent crops of small ulcers Healing generally occurs in 1 to 2 weeksNot preceded by vesicle and exhibit no virus-infected cells
48Treatment: Oral hygiene Avoiding spicy food Oral rising with sodium bicarbonateAnalgesicsAntisepticsAnti – inflammatory agentsAntimicrobial and corticosteroids
49Nomaalso known as cancrum oris or gangrenous stomatitis, is a gangrenous disease leading to tissue destruction of the face, especially the mouth and cheek.Noma (derived from the Greek "nomein" meaning "to devour") is a devastating gangrenous disease which attacks children, quickly destroying their mouth, nose, and face, and which can prove fatal after just a few weeks. Noma, also known as cancrum oris, seems to start on the gum and extends outwards to the cheeks and lips.
50NOMA FACTS NOMA FACTS Mainly attacks children 2-14 years old. Africa accounts for the majority of the cases.The World Health Organization estimates that 100,000 children contract noma every year.Without treatment, the mortality rate is 70-90%.Most victims starve to death because their jaw muscles are literally eaten away and they cannot chew; others die as the infection spreads.
51key players in the process : Fusobacterium necrophorumPrevotella intermedia Borrelia vincentiiPorphyromonas gingivalisTannerella forsynthesisTreponema denticolaStaphylococcus aureus
52The reported predisposing factors include: Malnutrition or dehydrationPoor oral hygienePoor sanitationUnsafe drinking waterProximity to unkempt livestockRecent illnessMalignancyAn immunodeficiency disorder, including AIDS
53Symptoms: The early features of noma include soreness of the mouth, a swollen tender cheek,a foul-smelling purulent oral discharge,fetid odor in the mouth of the affected child,swelling of the regional lymph nodes,anorexia,grayish-black discoloration of the skin in the affected area.The long-term effects of Noma depend largely on the anatomic sites of the lesion, the extent and severity of tissue destruction and the stage of development of the dentition and facial skeleton prior to onset of the disease.
54Treatment:The progression of the disease can be halted with the use of antibiotics and improved nutrition;however, its physical effects are permanent and may require reconstructive plastic surgery to repair.Reconstruction is usually very challenging and it should be delayed until full recovery (usually about one year following initial intervention)
