Working length determination is an important step for a successful root canal therapy in deciduous or permanent teeth. The main objective of this study is to evaluate the association between age, gender, tooth number, number of visits with working length of mandibular second primary molar. This was a retrospective, institutional based study. Sample size was 298. Data about patients below 18 years who underwent root canal treatment in the mandibular second primar molar in a period of june 2019 to march 2020 were collected. Excel tabulation was done and data was transferred to SPSS software. T test and pearson correlation was done to compare the age, gender, tooth number, number of visits with working length. p<0.05 was considered statistically significant. The mean age of males was 5.59 ± 1.8 and females was 5.68 ± 2.2 . The mean working length of males was 12.04 ± 2.8 and females was 12.34 ± 2.8. There was a statistical significant association found between the number of visits and working length. There was no statistical association found between age and working length, gender and working length, tooth number and working length.
