The pulpally affected posterior teeth were noted down by single examiner to rule out possibility of operatorís error. All the data thus obtained was arranged in a tabulated form and analysed using SPSS software. Results: The mean age of the subjects was 32.54+/- 4.56 years. More number of female patients were presented with pulpal involvement than males. More molars had pulpal involvement than premolars. Mandibular first molar was the most infected tooth among all the posteriors.Conclusion: The present study clearly demonstrated significant proportion of subjects with pulpal infection, clearly indicating lack of oral health awareness.
