This research was done on patients who were suffering from tolerable painful lesions in the oral cavity. These lesions were oral ulcers with soft consistency and the size of the oral ulcers varied from 2 mm to 8 mm respectively. They were treated using L-ornithine-L-aspartate & Silymarin suspension/ syrup and tablet Ursdeoxycholic acid 300 mg.

Introduction – All about oral ulcers

Oral ulcers are painful lesions in the oral cavity. They vary in size and their symptoms depend on the type of ulcer.

Etiology: The exact cause is still not known and the etiology varies from person to person. However, there are some common causes and aggravating factors such as:

  • Biting the tongue or inside of cheek( buccal mucosa).
  • Braces, poor fitting dentures and other appliances that may rub against the mouth and gums (gingiva).
  • A deficient restoration/ filling.
  • Stress or anxiety.
  • Hormonal changes during pregnancy, puberty & menopause.
  • Medications including beta blockers and painkillers.
  • Genetic factors.
  • Conditions such as Celiac or Crohn’s Disease, Vitamin B 12 or Iron deficiency, or a weakened immune system that may trigger oral ulcers to form.

Types of oral ulcers :

Typically, oral ulcers appear on the inner cheeks (buccal mucosa) and last from 1 to 2 weeks. Most are harmless. There are three main types of oral ulcers.

  • Minor Ulcers: This type can range in size of about 2mm upto about 8 mm. These ulcers typically take upto 2 weeks to get better and will cause some pain.
  • Major Ulcers: Bigger than minor ulcers, major oral ulcers are often irregular in shape, maybe raised and penetrated deeper into the tissue than minor oral ulcers.They can take several weeks to go away and are likely to leave scar tissue when they clear.
  • Herpetiform Ulceration (HU): Herpetiform oral ulcers get their name because they resemble sores associated with Herpes. Unlike Herpes, Herpetiform Ulceration (HU) is not contagious. HU recur very quickly and it may appear that the condition never gets better.

Symptoms of major or minor ulcers:

  • One or more painful sore that may appear in buccal mucosa, the roof of the mouth, the labial mucosa, or the tongue.
  • The appearance of round lesions that have red edges are yellow, white or gray in middle.

Symptoms of herpetiform ulceration (HU) lesions:

  • HU lesions may appear as extremely painful oral ulcers in the mouth.
  • Recur very quickly .
  • May increase in size , eventually coming together to form a large ragged ulcer.
  • Appear anywhere in mouth.

They tend to be found more in females than males and are common in older adults.

This research article, provides a new understanding that oral ulcers (soft consistency) whose size ranges from 2mm to 8mm can be treated by using the drugs named L-Ornithine-L-Aspartate, Silymarin and Ursdeoxycholic Acid.

Case report

This clinical research was done on 7 male patients, aged between 25 to 35 years of age. These patients visited the author’s private dental practice, with the complaint of painful, but tolerable oral lesions. They did not have any medical comorbodities or any history of tobacco chewing, smoking or intake of tobacco in any other forms.Their dental history was non significant -they did not have any carious tooth, broken restorations or use of any dental prosthesis.

On clinical examination, these lesions were found to be present on buccal mucosa & gingiva. The consistency was soft and the size ranged from 2mm to 8 mm. It was diagnosed that the patients were suffering from minor oral ulcers.

Informed consent was taken from the 7 patients who became the part of this research.All these 7 male patients were prescribed:

  • L-ornithine-L-aspartate, Silymarin suspension/ syrup – one and half tablespoon once a day, daily after food, for 10 days and
  • Tablet Ursdeoxycholic acid 300 mg once a day ,daily after food ,for 10 days

It is important to mention that these patients were not prescribed the typical medications for oral ulcers. They were not prescribed antibiotics, topical chlorhexidine gluconate gels, topical Triamcinolone dental paste or topical lignocaine or benzocaine hydrochloride gels. They were also not prescribed any analgesics or NSAIDS, mouthwashes or any other medications.

The patients were advised liver function tests (LFT). Follow up was advised after 10 days along with the report of this test.

At the 10 day follow-up, all 7 patients completely got healed from oral ulcers. The diagnostic reports were evaluated and all the values of various parameters of LFT were in normal range.






A total of 7 patients were taken into account for this research.Their oral ulcers were healed after taking the prescribed drugs; namely L-ornithine-L-aspartate, Silymarin And Ursdeoxycholic acid.

  • L-ORNITHINE-L-ASPARTATE: L-ornithine-L-aspartate infusion injections are used to treat skin problems like skin ulcers. It is a chemical that is broken down by the body to increase the levels of two amino acids, namely ornithine & aspartic acid. Ornithine and aspartic acid helps to reduce levels of the toxic chemical ‘ammonia ‘ in the blood.

People use it for reduced brain functions due to advanced liver disease (hepatic encephalopathy). It is also used for athletic performance but there is no good scientific evidence to support this use.

Preautions and warings before using l-ornithine-l-aspartate:

  • L-ornithine-L-aspartate is possibly safe when used in doses upto 18 grams daily for upto 6 months. It is generally well tolerated.
  • Pregnancy and lactation: There isn’t enough reliable information to know if L-ornithine-L-aspartate is safe to be used during pregnancy or lactation.
  • SILYMARIN: For many years, Silymarin has been used as a ‘hepatoprotectant’. Although the mechanism of action is not completely known, Silymarin has been reported to have anti oxidant, immuno-modulatory, anti fibrotic, anti inflammatory, anti proliferative and anti viral properties. Silymarin has a short half life and quick conjugation in liver with the principal excretion in bile.

Some reported side effects of Silymarin are stomach pain, loss of appetite, diarrhoea but these are not observed in every patient. It may not be safe during pregnancy or lactation.

  • URSDEOXCYHOLIC ACID: Ursdeoxycholic Acid is a bile acid component with anti apoptotic ,anti oxidant and anti inflammatory properties. Ursdeoxycholic Acid is used to dissolve gall stones in various liver related disorders such as cirrhosis, sclerosing cholangitis and liver dysfunction. This medicine acts a dissolving agent, which reduces cholesterol content in bile.

Ursdeoxycholic Acid is contraindicated in following cases/ situations:

  • Ursdeoxycholic Acid is contraindicated in intestinal ulcers or bleeding.
  • If the patient has a recent surgery involving any part of intestine.
  • If the patient is suffering from inflammation/blockage of gall bladder.

Side effects of Ursdeoxycholic Acid include vomiting, nausea, diarrhoea etc.

It must be mentioned that L-ornithine-L-aspartate, Silymarin And Ursdeoxycholic acid are liver disease medicines. There is enough medical literature present which states that oral ulcers can manifest due to various liver diseases.

The patients were advised liver function tests (LFT). These tests measures the following parameters:

  • Alanine Transaminase(ALT)
  • Aspartate Transaminase (AST)
  • Alkaline Phosphatase (ALP)
  • Gamma Glutamyl Transferrase (GGT)
  • Serum Bilirubin,Prothrombin Time(PT)
  • International normalised ratio (INR)
  • Total Protein & albumin.

Increase in any of the above following parameters of LFT would have indicated a underlying liver disease and would have additionally indicated that the treatment including the drugs L-ornithine-L-aspartate, Silymarin And Ursdeoxycholic acid 300 mg were not working well to heal the oral ulcers.

The normal LFT reports of the 7 patients denoted that the patients were not having any liver problems and the oral ulcers were not due to any liver disease. Their Liver Function Test (LFT) also denoted that the treatment including the drugs L-ornithine-L-aspartate, Silymarin & Ursdeoxycholic acid worked well to heal their oral ulcers as no other medicines were given along with them.


From the above mentioned clinical research it can be concluded that to treat oral ulcers (soft consistency) of size from 2mm to 8mm, drugs such as L-ornithine-L-aspartate, Silymarin & Ursdeoxycholic acid can be prescribed, without prescribing any antibiotics, NSAIDS, Analgesics, mouthwash, or topical gels like chlorhexidine gluconate and triamcinolone.


Limitation of this clinical research are as follows:

  • Sample size – The sample size was very limited.
  • Lack of literature – There is not enough medical literature present which strongly gives the evidence that these medications can cure oral ulcers of soft consistency which ranges in size from 2mm to 8mm.
  • Cost effectiveness – The prescribed medications are not cost effective, as compared to the other typical treatments.
  • Gender and age bias – There is not enough scientific evidence which suggests that these medications can treat oral ulcers of people of both genders or of much different age groups than the one taken into account in this research.

Special note – Difference between oral cancer & oral ulcers

Some clinicians find it challenging to differentiate between oral cancer and oral ulcer. Both are distinctive in their symptoms. Oral cancer is a type of oral ulcer but not all oral ulcers are oral cancers. Persistent oral ulcers require observation – a non healing ulcer is a cause of concern.

There are some fundamental differences between oral ulcers and what might be oral cancer.

  • Oral ulcers are often painful areas or lesions whereas oral cancer is not.
  • Oral ulcers will clear up in about 2 weeks whereas oral cancer will not heal and will often spread (metastasis).
  • Oral cancer patches may be rough, hard and not easy to scrape off.
  • Oral cancer is often a mix of red and white areas or large white areas,that appear in tongue,the back of the mouth,the gingiva or the buccal mucosa.
  • Oral cancer is often linked to heavy drinking or tobacco use.
