Organization of the findings associated with various diagnostic aids plays a key role in formulating the treatment plan of the patients undergoing dental and medical treatment. Enhanced consistency in diagnosing and classifying prosthodontic patients is the basic purpose of various classification systems. Hence, we planned this study to classify partially edentulous patients and completely dentate patients at the undergraduate clinics using the prosthodontic diagnostic index (PDI).

Materials and methods

This study included classification of 13,599 edentulous patients who attended the clinics of undergraduate students of all the levels. Screening of all the patients was done radiographically with a digital orthopantomograph (OPG), and the data were saved in the computer system. The intraoral periapical radiographs (IOPA) taken for all the affected areas were also saved in the system. Based on the OPG and IOPA, the patients were classified into various classes. All the data of the patients were recorded and analyzed.


Total number of patients screened was 17,220, out of which 3,621 were under 18 years of age and were excluded from the study. Most of the patients belonged to the age group of 31 to 45 years: 5,360 (39.4%) patients (3,817 [43.0%] males and 1,543 [32.5%] females) were class I; 2,730 (20.0%) patients (1,729 [19.5%] males and 1,001 [21.1%] females) were class II; 4,576 (33.7%) patients (2,835 [32.0%] males and 1,741 [36.8%] females) were class III; and 933 (6.9%) patients (483 [5.5%] males and 450 [9.5%] females) were class IV.


There is a need to introduce PDI as a screening tool during the initial examination of the patient and to achieve a proper distribution of the patients among various levels of students, interns, and postgraduates.

Clinical significance

Introduction of PDI will improve the treatment planning and prognosis of edentulous patients.
