Keywords Miller’s Classification; Gingival Recession Defects; Post-Operative; Periosteal Pedicle Graft Technique; Cemento-enamel Junction Introduction Recent scientific literature on gingival recession classification systems has raised serious question marks on the credibility of the most popular Miller’s classification system [1, 2]. The reasons behind such criticisms emerged from the fact that Millers classification lacked the desirable scientific qualities of a classification system as suggested by Murphy [2]. In order Journal of Dentistry and Oral Sciences An Open Access Journal Abstract Despite its limitations and drawbacks the Miller’s classification system continues to be the most popular system for classifying gingival recession defects (GRDs), however, recent studies have challenged the use of Miller’s classification system and many new classification systems have been proposed. Mahajan’s classification system is a modification of Miller’s classification and has been found to be reliable in identifying GRD. Since predicting the pathogenesis and prognosis of the disease process in GRDs is an essential requirement for a valid classification system and till date no study is available in the literature which assesses the predictive capacity of the modified Millers classification, the present study was done to evaluate the same. A total of 21 GRDs were classified according to the modified Miller’s classification and were treated subsequently. At the end of the study the modified Miller’s classification system was found to have satisfactory predictive value and the post-operative results correlated well with the pre-treatment prognosis for various recession classes.
