A Literature Review of Age Estimation using Dental Images

Odontology is the study of dental disease and structure. The human jaw consists of 32 teeth divided into four categories: incisors, canines, premolars, and molars. Every human has two sets of teeth in their life, a set of temporary teeth and a set of permanent teeth. To detect issues in the jaw, the dentist usually suggests scans such as OPG, CBCT, or CTs. OPG is a panoramic X-ray of the upper and lower jaws, whereas CBCT is a medical imaging procedure that uses divergent X-ray computed tomography. While OPG X-rays are generally preferred by dentists since they do not leave any radiation on the patient's anatomical tissues and are effective, easy, and quicker to analyze, CT scan images offer more detailed information than ordinary Xrays. In this paper, we'll go over many methods and models that other researchers in the same field have used to determine a person's age just by looking at scans or X-rays. The radiographs can also be used to identify other patterns, such as missing teeth, impacted teeth, the contour of the jaw, and the growth of the molar teeth. Some of these are also very important in the age estimation procedure
