Abstract
Focused Clinical Question: Often, there is a clinical dilemma in classifying patients based on the Dummett–Gupta oral pigmentation index (DOPI). Can the subjectivity of DOPI classification be overcome?Summary: DOPI classification, although time tested, is dependent on the visual acuity of the examiner and hence is subjective. Because of this, there is room for clinical uncertainty when classifying mild (Class I), moderate (Class II), and severe (Class III) pigmentation. This problem can be overcome by using image analysis software to assign intensity values to every class of gingival pigmentation.Conclusions: Objectivizing DOPI classification will eliminate clinical uncertainty and interexaminer variability in classifying patients. This value will give a precise idea about the extent of depigmentation and degree of repigmentation when various techniques are considered and compared.
