1. The document discusses several types of malignant lesions that can occur in the oral cavity, including squamous cell carcinoma, basal cell carcinoma, Ewing's sarcoma, osteosarcoma, and multiple myeloma.
2. Squamous cell carcinoma is the most common type of oral cancer, making up over 95% of oral cavity malignancies. Risk factors include use of tobacco, betel nut, and alcohol.
3. Multiple myeloma is a neoplasm of bone marrow cells that resemble plasma cells. It presents with pain, swelling, and destruction of bone. Treatment involves chemotherapy and radiation therapy.
This document discusses potentially malignant oral disorders including leukoplakia, erythroplakia, oral submucous fibrosis, actinic cheilitis, and lichen planus. It describes the clinical presentation and risk factors for each condition. Biopsy is recommended for lesions to determine the level of dysplasia and guide treatment, which may include surgical excision depending on the diagnosis and severity of dysplasia. While not all premalignant lesions will transform into cancer, some like erythroplakia have a high risk of already representing severe dysplasia or early cancer.

The document discusses the definition and classification of potentially malignant disorders. It provides details on the history, etiology, clinical features and types of oral leukoplakia. Diagnosis, treatment options including photodynamic therapy and prognosis are also summarized. Histopathological grading and staging of oral leukoplakia are described.
Leukoplakia and erythroplakia are two clinical lesions widely considered to be premalignant.
The term leucoplakia describes a white plaque that does not rub off and cannot be clinically identified as another entity. Most cases of leukoplakia are a hyperkeratotic response to an irritant and are asymptomatic, but about 20% of leukoplakic lesions show evidence of dysplasia or carcinoma at first clinical recognition.
An erythroplakia is a red lesion that cannot be classified as another entity. Far less common than leukoplakia, erythroplakia has a much greater probability (91%) of showing signs of dysplasia or malignancy at the time of diagnosis.

Premalignant & malignant diseases of oral cavity ii nMohammad Manzoor
1) Leukoplakia and erythroplakia are common precancerous oral lesions caused by factors like tobacco, alcohol, and HPV infection. Leukoplakia has a 3-25% risk of transforming into oral cancer while erythroplakia has over a 50% risk.
2) Oral cancers are usually squamous cell carcinomas that occur late in life, commonly on the lips, tongue, and floor of mouth. Risk factors include tobacco, alcohol, HPV infection and leukoplakia/erythroplakia. Prognosis is best if caught early but many cases are advanced at discovery.
3) Common benign salivary gland tumors
This document discusses clinical features that can indicate oral premalignancy. It begins by stating that clinical classification of oral lesions is difficult and subjective, while histopathology is more accurate for determining premalignant change. Leukoplakia and erythroplakia are two clinical lesions often considered premalignant, though leukoplakia has a low risk while erythroplakia has a high (91%) risk of dysplasia or malignancy. A biopsy should be considered for any persistent mucosal lesion to determine premalignant changes. Common sites of oral premalignancy are the buccal mucosa, palate, and floor of the mouth in individuals aged 50-69. Surgical

This document discusses oral premalignancies, which are lesions with potential for malignant transformation. Erythroplakias carry the highest risk, while some leukoplakias have a lower risk depending on the degree of dysplasia found histologically. Biopsy is important to assess dysplasia. Risk factors include erythroplakia, sublingual keratosis, snuff or tobacco use, lichen planus, lupus erythematosus, and oral submucous fibrosis. Management includes stopping habits, treating infections, biopsy, and ablation or excision of high risk lesions.
This document provides information on precancerous lesions and conditions that can occur in the oral cavity. It defines precancerous lesions as morphologically altered tissue that is more likely to develop into cancer, and precancerous conditions as a general state of increased cancer risk. The document describes several common precancerous lesions including leukoplakia, erythroplakia, and carcinoma in situ. It also covers precancerous conditions such as oral lichen planus and oral submucous fibrosis. For each condition, it discusses epidemiology, clinical presentation, histopathology, risk of malignant transformation, and management approaches.

This document discusses normal variations in oral mucosal color and describes common white and red lesions seen in the oral cavity. It provides details on the clinical presentation, etiology, and treatment of various conditions including leukoplakia, lichen planus, oral candidiasis, actinic cheilitis, nicotine stomatitis, geographic tongue, and lupus erythematosus. Inherited white lesions like leukoedema and white sponge nevus are also summarized, with an emphasis placed on distinguishing benign lesions from premalignant disorders.
This document discusses precancerous lesions in the oral cavity. It begins by introducing oral cancer as an important entity and notes that some cancers initiate de novo while others are preceded by oral precancerous lesions and conditions. It then defines premalignant lesions and conditions and discusses new classifications for oral potentially malignant disorders into four groups based on etiology and pathogenesis. Specific premalignant lesions like leukoplakia, erythroplasia, and carcinoma in situ are then described in detail including their clinical features, histopathology, diagnosis and differential diagnosis.
- Precancerous lesions of the oral cavity include premalignant lesions like leukoplakia, erythroplakia, oral submucous fibrosis, and lichen planus as well as premalignant conditions.
- Leukoplakia presents as a white patch that cannot be scraped off. Erythroplakia appears as a bright red patch. Oral submucous fibrosis causes stiffness of the oral mucosa and trismus.
- Risk factors include tobacco use, betel nut chewing, and poor oral hygiene. Histopathological examination is needed for diagnosis. Management involves eliminating risk factors, surgical excision of high risk lesions, and close follow up
This document discusses leukoplakia, a white patch or plaque that develops in the mouth and cannot be wiped away. Leukoplakia can occur on the tongue, cheeks, gums and affects 1.5-12% of the population, especially older males. Risk factors include tobacco, alcohol, and HPV. Leukoplakia may be precancerous and has a higher risk of turning into oral cancer, especially in smokers. A dentist will examine any white patches and perform a biopsy of suspicious areas to examine under a microscope for signs of cancer. Treatment options depend on the biopsy results but may include removing the patch by surgery or laser. Quitting smoking and limiting alcohol can help prevent leuk
Traumatic lesions and chemical injuries can cause transient nonkeratotic white lesions of the oral mucosa. Aspirin, silver nitrate, and other agents can burn and damage tissue if retained in the mouth for long periods. Leukoplakia is the most common oral precancer, appearing as a white patch that cannot be characterized as any other disease. Risk of malignant transformation is greater for leukoplakia than normal mucosa. Tobacco use is strongly associated with leukoplakia, which affects mostly males. Microorganisms may also play a role in some cases.
Premalignantlesions and conditions by Dr. Amit T. Suryawanshi, Oral Surgeon,...All Good Things
Hi. This is Dr. Amit T. Suryawanshi. Oral & Maxillofacial surgeon from Pune, India. I am here on slideshare.com to share some of my own presentations presented at various levels in the field of OMFS. Hope this would somehow be helpful to you making your presentations. All the best.
Leukoplakia is a white patch or plaque that develops in the mouth and cannot be wiped away. It affects 1.5-12% of the population, usually those over age 40, and prevalence increases with age. Leukoplakia has various clinical forms and ranges in appearance from flat and uniform to raised or irregular patches. A biopsy is needed to examine the tissue for signs of dysplasia or oral cancer. While most leukoplakia is harmless, some may develop into cancer over time, so prevention focuses on lifestyle changes like quitting smoking and reducing alcohol.
This document provides a classification and overview of various tongue disorders and conditions. It discusses inherited, congenital, developmental anomalies as well as disorders affecting the lingual mucosa, body of the tongue, and tumors of the tongue. Specific conditions covered include geographic tongue, hairy tongue, median rhomboid glossitis, macroglossia, fissured tongue, ankyloglossia and more. For each condition, the document provides details on etiology, clinical features, management and related syndromes.
Oral cancer screening involves examination of the mouth by a dentist or doctor to identify signs of cancer early. Screening methods include visual examination with tools like a mouth mirror [1], as well as adjunct tests to identify abnormal cells, like oral cytology or brush biopsy [2]. Additional aids like vital stains that detect high nucleic acid areas can specify sites for biopsy [3]. Early detection through regular screening is important as 5-year survival rates for oral cancer remain below 50% [1].
Oral leukoplakia is characterized by thick white patches that form in the mouth. It is usually caused by risk factors like tobacco use, alcohol consumption, and HPV infection. A definitive diagnosis requires a biopsy to examine the tissue under a microscope. Leukoplakia has the potential to progress to oral cancer so treatment options aim to remove or destroy the patches, especially for higher risk cases. Regular screening is important for early detection and management.
Early detection of oral cancer can save lives. Oral cancer involves regions in the oral cavity and oropharynx, including the lips, tonsils, tongue, cheeks and other areas. Precancerous lesions and conditions can be detected through visual examination techniques like toluidine blue staining, VELscope, chemiluminescence and the Identafi system. Salivary biomarkers like proteins, genes, microbiota, oxidative stress markers and interleukins also show promise for early detection of oral cancer. Genetic changes in oncogenes and tumor suppressor genes influence tumor proliferation, progression, angiogenesis and metastasis.

Vital staining techniques are used to aid in the early detection of oral cancer and precancerous lesions. Some commonly used vital stains include toluidine blue, Lugol's iodine, methylene blue, and acetic acid. These stains work by selectively binding to or bringing out color changes in abnormal cells and tissues. For example, toluidine blue selectively stains nucleic acids in dysplastic cells, while Lugol's iodine brings out a color change in glycogen-deficient areas that may indicate malignancy. Vital staining is a simple, quick, and inexpensive chairside technique that can help clinicians detect suspicious lesions earlier and guide biopsy. However, vital stains also have some
The document discusses the VELscope oral cancer screening device. It begins by explaining what oral cancer is and its risk factors. It then describes how oral cancer screening can detect it early when treatment is most effective. The VELscope uses fluorescent light to detect abnormalities invisible to the naked eye. The device was developed over many years of research. It is easy to use, affordable, and can document suspicious areas found. The VELscope works by exciting tissue molecules that then emit light, allowing abnormalities to be seen. Catching oral cancer early through screening like with VELscope can significantly increase survival rates.

This document provides tips and instructions for using a PowerPoint presentation on oral cancer. It discusses how to actively engage students by starting with blank slides to elicit their existing knowledge on topics before showing slides with content. It also recommends revisiting slides at the end to reinforce learning. The presentation covers various topics related to oral cancer including introduction/history, relevant anatomy/physiology, etiology, pathophysiology, pathology, classification, clinical features, investigations, management, prevention, and guidelines.
Leukoplakia is a white oral lesion that cannot be characterized as any other lesion and has a malignant potential of 15.6-39.2%. Extrinsic factors like smoking and intrinsic factors like old age and nutrition can cause it. Clinically, it can be solitary or multiple and appear white on sites like the buccal mucosa or tongue. Diagnosis involves staining with Toluidine blue dye and biopsy. Treatment includes stopping causative habits, photodynamic therapy, topical chemotherapy, surgery, or chemoprevention with vitamins, minerals, or retinoids. Long term review is important after treatment due to risk of recurrence.
1. The document discusses cancers of the oral cavity, including risk factors, etiology, pathogenesis, clinical presentation, diagnosis, treatment and prevention. It notes that over 90% of oral cancers are squamous cell carcinoma, which commonly present as lumps or ulcers in the lip or tongue.
2. Tobacco use, alcohol consumption, and chewing betel nut are among the strongest risk factors. HPV infection is also linked to some oropharyngeal cancers. Other risk factors include age, gender, diet, sunlight exposure, and certain medical conditions or genetic syndromes.
3. The etiology of oral squamous cell carcinoma is multifactorial but strongly related to lifestyle habits like smoking, alcohol use, and
Three cases of oral lesions are described:
1) A nodular leukoplakia on the right commissure was found to be severe epithelial dysplasia on biopsy.
2) A clinically suspicious leukoplakia on the left buccal mucosa was found to be early squamous cell carcinoma on biopsy.
3) A homogenous leukoplakia in the floor of the mouth of a smoker was found to be hyperkeratosis on biopsy.
The document discusses oral cancer including its definition, types, risk factors, causes, pathophysiology, clinical features, diagnostic evaluation, management including medical, surgical and nursing management, prognosis, and nursing diagnoses. Oral cancer is cancer of the mouth and throat, caused by factors like tobacco and alcohol use, and presents with symptoms such as sores or lumps that don't heal. Treatment involves surgery, radiation, chemotherapy and rehabilitation to remove cancer and manage symptoms.
The document provides information about oral cancer. It discusses that oral cancer rates are highest in Papua New Guinea and Bangladesh. The most common sites for oral cancer are the tongue, tonsils, gums and floor of the mouth. Risk factors include tobacco use, alcohol, HPV infection and sun exposure. Symptoms can include sores, lumps or swelling in the mouth. Diagnosis involves examination, biopsy and imaging. Treatment options depend on the cancer type and stage but may include surgery, radiation and chemotherapy. Prevention strategies incorporate limiting tobacco, alcohol and sun exposure as well as regular dental exams.
8 role of profession in prevention of oral cancer 03Lama K Banna
The dental profession plays an important role in detecting and preventing oral cancer. Early detection of oral cancer through examination of suspicious lesions can prevent tissue destruction and metastasis, greatly improving a patient's chance of survival. Dentists should be aware of the variable appearance of oral cancer and consult specialists when suspecting a lesion. Simple tests like cytology and the toluidine blue test can help dentists diagnose oral cancer, with early detection and treatment preventing an estimated 80% of oral cancer deaths.
oral cancer is the common melignancy in male and can leads to death of patient and social isolation among patient this ppt help in knowing the condition and refers by nurses for their knowledge and application in their clinical practice
Cancer of the oral cavity accounts for approximately 3% of all malignancies diagnosed annually in 270,000 patients world-wide. Oral cancer is the 12th most common cancer in women and the 6th in men. Many oral squamous cell carcinomas develop from potentially malignant disorders (PMDs). Lack of awareness about the signs and symptoms of oral PMDs in the general population and even healthcare providers is believed to be responsible for the diagnostic delay of these entities.
Cancer is a disease of the cells in the body. The body is made up from millions of tiny cells. There are several types of oral cancers, but around 90% are squamous cell carcinomas originating in the tissues that line the mouth and lips.
Oral or mouth cancer most commonly involves the tongue.
Oral cancer includes cancers of the mouth and throat, accounting for 3% of cancer diagnoses yearly. It is most common in men over 40, and risk factors include tobacco, alcohol, HPV, and sun exposure. Symptoms can mimic other illnesses but often appear as sores or thick patches in the mouth, lips or throat. Dentists screen for oral cancer during regular checkups, which are important for early detection and better survival rates. Treatment depends on cancer stage but may involve surgery, radiation and chemotherapy. Continued dental care is also important during and after treatment.
Oral cancer is one of the most common cancers worldwide and constitutes the third most common cancer in developing countries. It affects lips and other intraoral sites. The main risk factors are tobacco, alcohol, poor diet/nutrition, viral infections, and chronic irritation. Precancerous lesions like leukoplakia and erythroplakia can develop due to these risk factors and have a higher risk of becoming cancerous. Prevention focuses on reducing risk factors through education, screening, and early detection/treatment of precancerous lesions. Diagnosis and management depends on the stage, with surgery and radiation used for early stages and palliative care for late stages.
The use of autofluorescence technology in the detectionmehrdad bayat
Tissue autofluorescence technology can help detect oral cancer. When normal oral tissue is exposed to blue light, it emits green fluorescence but abnormal tissue will appear dark. This property is used in devices like VELscope to examine the mouth. The document discusses several studies finding that VELscope had high sensitivity and specificity for detecting cancerous and pre-cancerous lesions compared to normal tissue. It can also help surgeons delineate diseased from healthy bone during fluorescence-guided procedures. While promising for screening, further research is still needed to evaluate autofluorescence's ability to differentiate malignant from benign lesions. In summary, autofluorescence visualization aids in oral cancer detection and surgery but requires more validation.

3. Oral cancer can never be diagnosed by any doctor other than dentist, we are responsible to detect it,thus we must be ready
for these lesions
Early detection is very important because even if the patient have been treated with radiation, surgery and chemotherapy in
advanced stage a 5 year survival rate were only for %55 of the patients
How can history and social habits affect the oral mucosa, can you list some factors?
Tobacco, alcohol ,previous cancer esp if its diagnosed before 2yrs , radiotherapy and etc..
Risk factors of oral cancers are tobacco , alcohol, chewing tobacco , age, betel quid ,marijuana , diet low of fruits and fibers
, HBV 16,18 and chronic gum disease
Chronic candida infection have been linked with oral cancer
These days there is an increased risk of oral cancer in young adult especially in USA. Hmm what is the contributing factor
in your opinion?
Its Marijuana , and it will continue to increase because of the low awareness level .
A risk factor that is found in India and southwest Asia is Betel quid, but can you mention a disease that transform to a
cancer by it?
Submucousal fibrosis that have 7.6% malignant transformation by it
4. Iron deficiency anemia accompanied with dysphagia and esophageal webs known as plummer-vinson syndrome have higher
chance to cancer
If there were leukoplakia in male and female, which one would have higher possibility of malignancy in your opinion,
considering that all other factors are the same?
The female patient.
If there were leukoplakia in smoker and another in non-smoker, which one in your opinion have higher possibility of
malignancy?
Sadly, it is the non-smoker, due to other potent carcinogens.
Immunosuppression increases the risk of oral cancer , do you know which cancer is usually associated with HIV?
Kaposi sarcoma
Carcinoma of the lip usually involves white middle aged men, can you guess why ?
White:due to low melanin level thus less protection Men: because usually occupies outdoor job old: the older is the pt the
more sun exposure
Sadly, African American have higher mortality rate in oral cancer, do you know why?
Simply because it get diagnosed at an advanced stage.
5. Do you know that there is a lack of skill in detection early oral cancer,which makes it more important to step up your
clinical skill
Bleeding, ulceration with pain ,elevation of lesion >3mm ,do you know which one of those are early clinical feature of oral
malignancy ?
None , those are actually considered late clinical features
Very Early oral malignancy will have a smooth or granular surface or asymptomatic ulcer with no bleeding or induration
Early signs of cancer are non-healing ulcer, thin patch of leukoplakia or erythroplakia especially when its in dangerous site
as lateral surface of the tongue or floor of the mouth
Other features involved are heterogeneity in color or thickness ,irregular border indurated and rolled borders
One of the early signs of oral cancer is thin leukoplakia which is a white patch or plaque that cannot be characterized
clinically or pathologically as any other disease.
The most common site of leukoplakia are buccal mucosa, alveolar mucosa, and lower lip.
But, lesions in the floor of mouth, lateral tongue, and lower lip are most likely to show malignancy.
6. Can you mention other Early Signs of Oral Cancer?
1-Persistent red and/or white patch,Prolonged hoarseness ,Nonhealing ulcer ,Progressive swelling ,Unusual surface changes
2-Sudden tooth mobility without apparent cause,Unusual oral bleeding or epistaxis
Do you have any idea of why most of the malignancy occurs at the floor of the mouth or lateral surface of the tongue?
Because carcinogens will tend to constantly pool in that area and those area covered by hinner nonkertinized membrane
Most lip cancers manifest on the lower lip at the mucocutaneous junction as a chronic small lump, ulcer, or scabbed lesion.
Carcinomas of the alveolus or gingiva are mostly seen in the mandibular premolar and molar regions, usually as a lump (epulis) or ulcer.
Carcinomas of the buccal mucosa are mostly seen at the commissure or in the retromolar area.
When should chronic oral lesion should be regarded with suspicion?
Older patient, induration, with fixation to underlying tissues, with any recent changes in appearance, with associated lymphadenopathy,
or with no obvious explanation for the lesion.
7. Screening aids of oral
cancer
1- standered
screening test:
COE (conventional oral examination)
2. Established
screening adjuncts:
Oral cytology-
-Oral brush biopsy
3. Vital staining:
-Toluidine blue (TB)
(tolonium chloride)
- Lugol's Iodine
- Methylene Blue
8. Conventional oral examination is performed by doctors, can you mentions any
requirement of it?
Adequate light and retraction of soft tissue
COE cannot discriminate between lesions that are progressive or become malignant
and those non-progressive counterparts.
COE is a useful tool in detecting some oral cancer lesions, it does not identify all
potentially premalignant lesions.
There is an adjunct way to detect oral cancer which is by using oral cytology
Oral cytology is carried out to detect cancer pre-invasive stage by use of exfoliative
cytology
9. But the sensitivity and specificity differs due to its subjectivity or due to the poor technique in obtaining
cells and smear preparation.
In order to decrease its subjectivity they developed oral CDx cytobrush which claims to collect the basal
layer cells non-invasively and assess the
dysplasia by computer-assisted neural network
its accuracy can be increased by using (DNA) cytometry, silver nucleolar organisation regions (AgNOR)
analysis
immunocytochemistry and fluorescent insitu hybridization (FISH).
We can also use staining likeToluidine blue that is believed to stain nucleic acids, it is used to detect
carcinomas but not dysplasia
It is not used as diagnostic tool in clinic due its false positive reading , do you know what that mean?
False positive means that the test was positive for cancer, even if the lesion was not.
10. recent study by Moyer, showed that TB stained evident lesions with high risk molecular
patterns and predicted risk
and outcome in cases where little to no microscopic evidence of dysplasia was present
Do you know what the dark and the light blue means in TB stain?
Dark blue=positive for lesions suspicious malignancy Light blue=positive for premalignant lesions unless proved
otherwise by biopsy
Can you mention the advantages and disadvantages of TB?
Adv: Specify area for biopsy, cheap, not invasive, disposable and 100% sensitivity
Disadv: taste , it can remain in the mouth for 4-6hrs and its false positive
11. There is another satin which is Lugol's iodine consisting of 10 parts of potassium iodide to 5 parts of
iodine
Lugol's iodine was used as an antiseptic.
Application of iodine results in brown or black color staining in areas containing glycogen .In areas
lacking glycogen, iodine is not absorbed and such areas remain colorless or turn yellow.
Can you name Advantages?
It can be used for non-keratinized stratified squamous epithelium, Simple, Low costs High sensitivity
with low false negatives, result are fast, no follow up to know the result
But It is an irritant, cause abdominal pain, heart burn and nausea, Allergic reaction to iodine, Induces
shock Less accurate when used in post-menopausal women.
Used routinely in patients at risk - those with head and neck cancer and Heavy smokers and drinkers.
12. Lugol's Iodine
consisting of 10 parts of potassium iodide to 5 parts
of iodine Application of iodine results in brown or
black color staining in areas containing glycogen .In
areas lacking glycogen, iodine is not absorbed and
such areas remain colorless or turn yellow.
Advantages:
1- Used for non-keratinized stratified
squamous epithelium
2-Simple and many doctors do it 3-cheap
4-High sensitivity results in a low proportion
of false negatives
5-Test results are immediate
6-Decreased loss to follow-up.
Disadvantages :
It is an irritant ,cause abdominal pain,
heart burn and nausea
Allergy to iodine induces shock
Less accurate when used in post-
menopausal women.
Applications
1-Used routinely in patients
at risk - those with head and
neck cancer
2-Heavy smokers and
drinkers.
13. The 3rd stain is Methylene blue It is a heterocyclic aromatic chemical
compound. At room temperature appears as a solid, odorless, dark-green
powder, which yields a blue solution when dissolved in water.
It is Cheap and less cytotoxic
Used as an Early detection of oral cancer,treat Alzheimer's disease and
Examine (RNA) or DNA under the microscope
14. Methylene Blue
It is a heterocyclic aromatic chemical compound. At room
temperature appears as a
solid, odorless, dark-green powder, which yields a blue
solution when dissolved in
water.
Advantages:
Cheap and less cytotoxic
Applications
1-Early detection of suspected oral cancer
2-Detect gastric, prostate, and bladder cancers
3-To treat Alzheimer's disease
4-Examine (RNA) or DNA under the microscope
15. Another adjunct way to COE is Chemiluminiscence .
it is the emission of light from a chemical reaction which is of varying degrees
of intensity with colors that span the visual spectrum.
It involves the use of an oral rinse with a 1% acetic acid solution for 1min
followed by another examination under blue/white light
16. 1-The theory behind this technique is that the acetic acid removes the glycoprotein barrier
and slightly desiccates the oral mucosa;
2-the abnormal cells of the mucosa then absorb and reflect the blue/white light in a
different
way with respect to normal cells.
Hence normal mucosa appears blue, whereas abnormal mucosal areas reflect the light
(due to higher nuclear/cytoplasmic ratio of epithelial cells)
17. Advantages
delineating the sharp borders between normal and abnormal oral mucosa and often
extended beyond the clinically identified outline
Malignant lesions could be recognized without the aid of adjunctive diagnostic Tools
To screen for the possibility of field cancer change in other parts of the apparently
normal mucosa.
It is used to diagnose leukoplakias and radiation mucositis
Identification of asymptomatic and clinically non-evident lesions
Diagnostic aid for the detection of oral cancer and pre malignant early lesions .
18. The adjunct way is VELscope .
When cells interact with light they become excited and re-emit light of varying colors (fluorescence) and
this can be detected by sensitive detectors
All tissues fluoresce due to the presence of fluorescent fluorophores with in them (autofluorescence)
Florescence spectroscopy and imaging can detect these substances and provide
characteristic spectra that reflect biochemical changes
19. Advantages
It takes only 1-2 min and is painless and non-invasive, with no stains or rinses required
Improves the distinction between normal and abnormal tissues
Useful adjunct to a thorough visual and digital soft tissue clinical examination
Possesses useful benefit in the determination of surgical borders and post-surgical
evaluations.
It covers large surface area, Non invasion method and Small lesions can be identified.
Disadvantages
heat from prolonged and close tissue examination may cause patient discomfort.
Limitations:
Analysis of small sample sizes, Lack of methodologically sound clinical trials
Insufficient use of histologic and molecular mapping
