Analysis of Palatal Rugae Morphology Before and After Orthodontic Treatment by a Digital Image Recognition System International Journal of Morphology
Xiu-Ping,Wu; Jian-Ning,Han; Pan,Fen; Yu-Jin,Wan; Li,Bing.
To analyze the accuracy rate of a digital image recognition system in matching the palatal rugae Morphology after orthodontic treatment, before orthodontic treatment and to provide theoretical evidence for individual identification in the field of forensic dentistry. High-resolution digital images of the palatal rugae were taken under particular conditions from each patient before and after orthodontic treatment. Features of each digital image were extracted using a digital image recognition system and included in the palatal rugae database. Using an MATLAB software system, information matching of the palatal rugae was performed. From the matching results, the accuracy rate of individual identification of orthodontic patients was 100 %, with a Euclidean...

Morphology and Volume of Maxillary Canine Pulp Cavity for Individual Age Estimation in Forensic Dentistry International Journal of Morphology
Li,Bing; Xiu-Ping,Wu; Hong-Shangguan,; Wu,Xiao; Ke-Ming,Yun.
Age estimation plays a very important role in individual recognition in forensic dentistry. Morphological data of 3D pulp cavity of maxillary canines were acquired by oral and craniofacial CT scans. In accordance with inclusion criteria, CT data of 103 patients (51 males and 52 females) were collected at the Department of Radiology, Stomatological Hospital, Shanxi Medical University, China from September 2015 to August 2016. Mimics 17.0 software was used to measure pulp volume of maxillary canines and tooth volume, and to calculate the ratio of pulp volume/tooth volume. SPSS 16.0 software was utilized to analyze and establish database. Linear regression analysis was applied to process data and to establish a linear regression equation for individual age:...
