Oral pathology

At Clinique MFML, we have the knowledge and know-how to detect and treat various oral pathologies.

Our expertise as a clinic specializing in oral maxillofacial surgery goes beyond the care associated with dental implants, orthognathic surgery or wisdom teeth extraction. One of the many facets of our surgeons’ specialist training is the knowledge and management of the majority of lesions and pathologies affecting the orofacial sphere.

Multiple diseases may be present in the oral and maxillofacial spheres, such as cysts, gingival lesions or malignant tumors. In many cases, they go undetected because they are not necessarily associated with pain. This is why it is important to undergo a routine examination to detect them.


Our expertise

Dr. Lenis has the expertise needed to treat the various cases presented to them. He has been trained to detect and treat different lesions that can be present in the mouth, jaw and face. After reviewing your medical history and an appropriate clinical examination, a biopsy must sometimes be performed.

The specimen collected thereafter will be sent to the pathology laboratory for analysis. Microscopic examination of the tissues collected will make it possible to establish the final diagnosis. Our specialist surgeons will then be able to determine the action to be taken and direct you to the most appropriate medical or surgical treatment.

Lesion types

There are several lesion types that can be found in the mouth and jaws, some of which have serious health implications. Here are some examples of the conditions treated by our specialist surgeons.

Soft tissue lesions

Different lesions in the mucosa of the mouth may occur. These vary in nature and clinical presentation. Upon clinical examination, they may include an outgrowth (a bump), a white or red plaque or an ulcer but are not necessarily painful. These legions have very diverse origins, ranging from fungal infection, chronic mucosal trauma to precancerous lesion. A soft tissue lesion, although asymptomatic, should be taken seriously and evaluated by one of our specialists. Discuss this with your dentist!

Bone lesions

Often detected during routine dental radiographs at the dentist, bone lesions can have serious consequences, such as loss of teeth, chronic infections and weakening of the jaw, which can lead to jaw fractures.

Different types of bone lesions exist. They are generally separated into two categories, cysts and tumors. Cysts associated with impacted teeth are one of the most common intra-osseous lesions. These are the direct result of prolonged tooth retention inside the bone. Whether the fault lies with the impacted teeth or originates within the bone, the lesions become an inconvenience and must be properly looked after and treated.

Malignant tumors and cancers

Oral cancer is a disease that affects more than 700 Quebecers and nearly 5000 Canadians every year. The main risk factors are smoking and alcohol intake. A white and/or red lesion, a persistent ulcer and a hard gingival mass are signs of a precancerous or cancerous lesion that might be identified by you or your dentist.

After observing one or more of these signs, you will be asked to consult an oral and maxillofacial surgeon. They may have to conduct a biopsy to make a diagnosis. In these cases, early detection and management are preferable.

Detection and prevention of oral pathologies: a team effort

In order to quickly detect oral pathologies and minimize the impact on your health, you should take the necessary precautions and regularly consult your dentist. By examining your mouth and teeth, your dentist can identify possible abnormalities and suggest a consultation with an oral and maxillofacial surgeon. These surgeons can perform the treatments that your condition requires. Your health is in good hands at our clinic.
