Forensic odontology has been an interdisciplinary part of forensic science for many years. In Malaysia, this forensic discipline has been practiced for more than two decades however it is still considered a new discipline as there are a limited number of specialists. To date, there are less than ten practicing forensic odontologists in Malaysia. Ma...

Statement of problem Additive manufacturing by selective laser melting (SLM) has been claimed to be less challenging than conventional casting of cobalt-chromium (Co-Cr) removable partial dentures (RPDs), providing significant improvements. However, how the physicomechanical properties of Co-Cr RPDs fabricated by SLM compare with those fabricated b...

This study presents a novel tool to predict temperature-exposure of incinerated pig teeth as a proxy for understanding impacts of fire on human teeth. Previous studies on the estimation of temperature-exposure of skeletal elements have been limited to that of heat-exposed bone. This predictive tool was developed using a multinomial regression model...

The common method of preparing teeth prior to DNA extraction involves cleaning, decontamination, drying and pulverisation. Moisture in post-mortem teeth can promote bacterial growth and hydrolytic damage that could contribute to DNA degradation, whilst also possibly reducing the efficiency of sample pulverisation and DNA release. Here we compared D...

Background The aim of this study was to compare the trabecular bone microstructures of anterior and posterior edentulous regions of human mandible using cone-beam computed tomography (CBCT) and micro computed tomography (µCT). Methods Twenty volumes of interests consisting of six anterior and fourteen posterior edentulous regions were obtained fro...

Objective The aim of this study was to compare the trabecular bone microstructures of anterior and posterior edentulous regions of human mandible using cone-beam CT (CBCT) and micro CT (µCT). Materials and methods Twenty volumes of interests consisting of six anterior and fourteen posterior edentulous regions were obtained from human mandibular cad...

Heat alters colour and crystallinity of teeth by destruction of the organic content and inducing hydroxyapatite crystal growth. The colour and crystallite changes can be quantified using spectrophotometric and x-ray diffraction analyses, however these analyses are not commonly used in combination to evaluate burned dental remains. In this study, th...

Dental information is one of the three scientific methods of identifying a deceased person. However, when an investigator is faced with dental ante-mortem information that indicates the deceased has had all his teeth extracted, it may be assumed that the dental information will not be useful, especially if no retained roots are visible in the post-...

This study was to compare the suitability and precision of xerographic and computer-assisted methods for bite mark investigations. Eleven subjects were asked to bite on their forearm and the bite marks were photographically recorded. Alginate impressions of the subjects’ dentition were taken and their casts were made using dental stone. The overlay...
