The pulp/tooth perimeter ratio of the maxillary canine was calculated by using AutoCAD software, and the patient's age was estimated by using a regression equation. Then, a comparison was made between the estimated age and the actual age using this method. The role of sex, tooth placement in each quadrant and decade of age was examined in this ratio.</span> <span new="" roman="" style="font-family:" times="">For analysis, linear regression and paired T-test and correlation coefficients according to age and gender were used in SPSS 16 statistical software.</span><span style="font-family:"Times New Roman",serif"></span></span></span></span><br>

As a result, the Pearson correlation coefficient between age and pulp/tooth perimeter ratio was r = -0/08. We discovered a negative and significant correlation between these two variables with a P= 0.024. Likewise, the correlation coefficient in women was calculated r = -0.087, which with P= 0.037, this correlation is also significant and inverse.</span><span style="font-family:"Times New Roman",serif"></span></span></span></span><br>

Thus, using the pulp/tooth perimeter ratio to estimate age in women is also valid.</span><span style="font-family:"Times New Roman",serif"></span></span></span></span><br>
