Colour of the lesionis very useful for detecting a lesion e.g., Leukoplakia (homogenous white lesion)
can be observed in persons who have tobacco consuming habit;Amalgam tattoo (pigmented lesion in
the gingiva due to faulty Class II amalgam restoration).
Radiographs are necessary for intrabony lesions for detecting whether it is radiolucent (for, e.g.,
ameloblastoma, keratocyst), radiopaque (for, e.g., osteoma, odontoma) or mixed (for, e.g.,
Pindborgtumor, Gorlin cyst). Certain lesions have a specific radiographic characteristic which helps in
diagnosise.g., cotton wool appearance of Paget disease, moth-eaten feature of osteomyelitis, sun-ray
manifestation of osteosarcoma, and ground glass appearance of fibrous dysplasia.
However, a dental clinician should not come to a diagnosis based on radiographic appearance only
because e.g., cotton wool appearance is not limited to Paget disease but can also observed in
condensing osteitis.
STEP 4: CLINICAL IMPRESSION
A dental clinician must correlate with history, age, gender, clinical characteristics (appearance, site, location,
signs and symptoms), radiological appearance and other possible causes before arriving to a definite
diagnosis.
EXAMPLES:
A white line on the buccal mucosa along the occlusal level is undoubtfully linea alba and it does not
need either investigations nor treatment.
Leukoedema - a bilateral white lesion on the mucosa which disappears while stretching buccal
mucosa. does not offer any difficulty in diagnosis. However, diagnosis is not always that simple.
Following flowchart gives a logical approach to a white lesion of the oral mucosa and diagnostic criteria for a
gingival growth or swelling.
