Introduction & Objective: The purpose of this study was to compare different parameters of mandible and to correlate them with age of fetus in lunar months. Thus we can arrive at the age of fetus with reasonable approximation. Materials and Methods: Study consists of fetal hemimandibles both right and left sides. Fetal age ranges from 4 th to 7 th lunar month. Sixty-four hemimandibles (32 mandibles) were collected from fetuses after their maceration. The measurements were performed Condyle-Coronoid (Co-Cp), Gonion-Coronoid (Go-Cp), Gonion-Gnathion (Go-Gn), Condyle-Gnathion (Co-Gn), Symphyseal height (SH), and Mandibular angle (MA) processes. Data was analyzed with SPSS software program and 't' test was performed. Statistically highly signifi cant positive correlation was found between CR length and Co-Cp, Go-Cp, Go-Gn, Co-Gn, and SH and a negative correlation was found between CR length and MA of both sides. Correlation coefficient of right and left hemimandibles were nearly equal. The regression equation for CR length was estimated by SPSS software program. Results and Conclusion: It is possible to arrive at the CR length of fetus with the help of regression equation. From CR length, we can easily predict the age using these hemimandibles.
