Description Of Mouth Ulcers With Pictures For Better Learning

Introduction: Ulceration in the  mouth is a common occurrence and it is important for the physician to distinguish between the simple benign ulcers from those which are malignant.

1. Traumatic: The diagnosis is usually obvious with the clinical history. Patients may have ill fitting dentures or sharp teeth. The ulcer usually heals when the precipitating cause is removed.

2. Aphthous Ulcers: Patients present with small, painful ulcers, usually inside the cheeks or lips. They heal in about one week but others may occur while the initial ulcer is healing. It may be secondary to stress, inflammatory bowel disease or an underlying debilitating disease,
On examination they are white, small, circular, deep , painful ulcers with surrounding erythema.

3. Infective: May be due to bacteria ( Acute ulcerative gingivitis), Viral ( herpes simplex), or fungal (Candidiasis) .

In Acute ulcerative gingivitis (also known as Vincent's angina) patients present with swollen gums with small ulcers, which may spread to the buccal mucosa. There may be bleeding from the gums along with constitutional symptoms like fever and malaise. There is associated tender lymphadenopathy.

Candidiasis is common and is seen in patients with diabetes, immunosuppresed states or debilitating
diseases. It appears as red patches on the buccal mucosa, which are covered with white patches of desquamated epithelium mixed with fungus.

Herpes Simplex presents as painful vesicles which ulcerate. The patient may be immuno-compromised.

Herpes zoster may sometimes occur on the palate in the distribution of the maxillary division of the trigeminal nerve. There will be severe pain and ulceration.

4. Neoplastic: Squamous cell carcinoma of the mouth occurs as ulcers with hard edges and bleed. Mostly seen in older patients and a history of leukoplakia may be present. Also other predisposing factors like smoking, syphillis, sharp tooth or long term use of spices may be present.

6. Connective Tissue Disorders: Oral ulcers may be associated with SLE but patients usually present with other features of the disease rather than for the oral ulcers.

  1. Hello, my name is Betty. i was diagnosed of HIV virus 4 years back. Before then, i was dating this Derrick guy. we had something great going on. Our love life only lasted for 8 months. the sixth and seven month of our relationship, i began feeling very weak every now and then. But i never suspected anything until I kept on experiencing different symptoms like having sore throats, constant headache, body weakness e.t.c. I decided to go for a medical check up. I was tested HIV positive. when the doctor broke the news to me, it was as if my whole world had crumbled. it dawned on me then that Derrick has been lying to me. i was very mad to an extent i almost committed suicide. But there was nothing i could do, other than weep and weep. ever since then, i have been spending heavily on medications, going from one medical clinic or the other so I can look healthy. Though since i was a kid, i love herbs a lot. i take herbal tea with grandma while growing so i am quite familiar with herbs. early last year, i was on the internet and on a particular health blog, to check for herbal medication as alternative. I saw many comments and read many testimonies. Until i came across a particular testimony on how Dr.ugo cured a patient from herpes simplex virus using pure natural herbs. i reached out to the doctor because I also was thinking Herpes had no cure. I told him about my HIV status.He encouraged me not to panic that he will help me get my deliverance. he prepared some herbs and sent them to me. The herbs were in four 70ml bottles and I took them morning and night. i used as he directed, and in less than three weeks, i started having appetite to eat plenty of food and i gained back my strength. the fourth week,I consumed all the herbal meds. He encouraged me to go for a test which i did. This time, the result was negative. I quickly contacted the doctor and informed him of the news. I immediately asked him to prepare for Derrick too. He did and sent it. Today, me and Derrick are HIV free. All thanks goes to God Almighty for healing us through Dr.Ugo. if you are having any kind of sickness at all, Dr.Ugo is the right person to talk to and i assure you, you will be glad you did. His email: ugoherbalhome@gmail.com you can also write him on WhatsApp +2348104990619.
