Objectives: To evaluate the diagnostic accuracy of PUFA index in assessing clinical consequences of untreated dental caries among Malaysian adult subpopulation as compared to Periapical Index (PAI) and conventional clinical diagnosis
Methods: Based on consecutive sampling,100 Malaysian adults who attended Primary Care Clinic at Faculty of Dentistry, University Kebangsaan Malaysia, Kuala Lumpur and fit into the inclusion criteria were examined. Caries experience was evaluated according to WHO criteria (DMFT index). Clinical consequence of untreated dental caries was assessed by the presence of pulpal involvement, ulceration, fistula and abscess (PUFA) index. Periapical status of all the teeth in the orthopantomograph (OPG) was scored using Periapical Index (PAI). All teeth were clinically diagnosed based on American Association of Endodontology pulp and periapical disease classification.
Results: Mean DMFT index was 10.55. Prevalence of PUFA > 0 was 95.7%(n=92). Mean number of teeth affected (PUFA) was 2.52. Out of 2422 teeth assessed, 15.0%(n=380) were diagnosed with pulpal infection, 7.2 %(n=172) periapical infection while the OPG showed presence of periapical lesions in 9.7%(n=182) teeth. The sensitivity of PUFA index was moderate (0.62, 0.84) but the specificity was high (0.98, 0.95) when compared with the pulpal and periapical diagnosis, respectively. Similar result was obtained when PUFA was compared with the PAI (sensitivity 0.73 and specificity 0.94).
Conclusions: PUFA index can be used to complement DMFT Index in assessing the consequences of untreated dental caries. The index performs adequately as a screening tool to indicate the affected tooth for further clinical and radiographic examinations to diagnose an endodontic disease.
