3D morphometric evaluation of palatal rugae among Malaysian Malay population.
Masters thesis, Universiti Sains Malaysia.
Abstract
Palatal rugae pattern may have a promising and interesting future for human
identification purpose. Previous studies showed that palatal rugae pattern has a lot of
morphological and dimensional characteristics that are different from a person to
another even among the identical twins. In fact, palatal rugae are anatomically
located in a well protected place, behind boons, teeth, cheeks and lips, which
provides a good alternative option for human identification in mass disasters and
accidents. This study aimed to evaluate the variability and uniqueness of palatal
rugae among Malaysian Malays using 3D dental models. A 3D Next Engine Laser
scanner (USA) was used to digitize plaster dental casts of 130 Malaysian Malay
patients (65 males and 65 females) obtained from the archive of Orthodontic Clinic,
Hospital Universiti Sains Malaysia. The resulting 3D models were highlighted using
Paint 3D software (USA) for the purpose of rugae shape assessment. Rugae size
category and direction were assessed using 3Matic research software (Belgium). The
classification method of Thomas and Kotze (1983) as described by Kapali et al.
(1997) was adopted. Palatal rugae uniqueness was performed by superimposing 42
pairs of digital models (21 models were duplicated from the same patients and 21
