STEP 1: COLLECTION
Information is collected through thorough history taking, which is usually neglected. It is a professional
responsibility for every clinician to know patient’s complete medical history since it may affect dental
treatment. Another importantthing is to take medication histories in order to prevent medication errors and
related risks to patients and also to detect drug-related clinical and/or pathological changes.

Although
diagnosis appears to be self-evident by inspection alone, existing diseases might be undetected and
untreated.

History taking promotes a good doctor-patient relationship and it also saves the necessity for
expensive laboratory procedures.
STEP 2: CLASSIFICATION
Oral lesions are categorized based upon:
Colour change (white, red, blue, pigmented or combined),
Loss of integrity of the mucous membrane (erosion, fissure, or ulcer, which may be primary or
secondary),
Growth or swelling,
Lesions involves tooth and/or bone, either alone or combined with other soft tissue lesions,
Syndrome
When an oral lesion is detected by a dentist, he/she should first try to categorize the lesion based on any of
these categories.
STEP 3: COMPARISON
Differential diagnosis plays a major role in diagnosing an oral lesion. Following factors are considered for
differential diagnosis:
Clinical appearance might predict the nature of the lesions.
Certain sites are common for some lesionse.g., Pyogenic granuloma is commonly seen in gingiva and
unlikely to be observed on floor of the mouth; Ranula is usually observed on the floor of the mouth
and is not on gingiva.
Palpation of the lesions provide an indication of the nature of the lesions.
