[Abstract] A method for estimating age based on occlusal wear of the teeth and palatine suture morphology has been widely used. This allows us to estimating age based on macroscopic findings. However, even if the living status and jaw growth are taken into consideration, the accuracy of this method is not sufficient. In this case, a marked difference was observed in estimated age between two methods based on the degree of occlusal wear and palatine sutures. To avoid this discrepancy, a number of approaches, including radiography, a comparison of the morphology of teeth using a study model, and data preparation employing dental charts are necessary. Some factors, such as distortion, growth and developmental disorders of the jawbone, diet, occlusal relationship, and habits often influence age estimation especially when the dental attrition degree of the tooth is used. When there is a discrepancy in the estimated age, caution should be exercised. There is an individual difference in the status of the synechia. We observed a case that misled us into presuming younger age. It is rare that estimated age is higher than a real age. Age estimation is performed from both sides of dental attrition and palatal suture in this time. This case demonstrated a large discrepancy in age estimation between dental attrition and sutures of the palatine bone.
