J Pak Dent Assoc Jan ;23(3):100-5.

PURPOSE: To compare the frequency of Inter-appointment pain by employing crown-down and step-back technique through visual analogue pain scale at different time intervals. METHODOLOGY: 60 patients were selected and divided in to two groups of 30 each. Group A has been instrumented by crown-down and Group B by step-back technique. Patients reported with inter-appointment pain after 24 hours and after 48 hours. STATISTICAL ANALYSIS: Data were collected and entered in SPSS version 10 for windows. Mean ± SD were presented for age of the patient and VAS. Male to Female ratio were presented for gender distribution. Chi-squared test were used to compare VAS between the two groups. A p-value of < 0.05 was considered as statistically significant. RESULTS: After 24 hours occurrence of inter-appointment pain was high in group B than group A but it is not statistically significant. After 48 hours inter-appointment pain was high in group B than group A but it is not statistically significant. CONCLUSIONS: The result of this study shows no significant difference in inter-appointment pain between crown-down preparation technique and step-back technique.
