The Reliability Of Bitemark Evidence: Analysis And Recommendations In The Context Of <strong>Malaysian</strong> Criminal Justice SystemA bare expression of the expert’s opinion has noevidential value at all. Unless he gives an explanationwhich supplies understanding of the subject which thecourt lacks, the court is in no better position than it wasbefore. 52A proper training will definitely produce farmore competent dental practitioners who can contributeeffectively in the field of forensic odontology.Having discussed thus far, there is an important pointthat needs consideration. In any forensic investigations, itis not infrequent that the practitioners in the criminaljustice system fail to appreciate the fact that the biologicalsciences (including dental science) cannot, in the presentstate of knowledge, be expected to deliver the exactitudeof the mathematical sciences. 53 Furthermore, Prettyargued that it is healthy within any discipline that somecontentious issues exist, since without an inquisitorialapproach no science would advance. 24 Therefore, althoughthe trainings should be aimed to improve the efficiencyof the forensic odontologists in Malaysia and create auniformity among them, bitemark evidence should not berejected as unreliable on the sole ground that there are stilldisagreements among the experts.CONCLUSIONThe reliability of bitemark evidence depends ontwo factors, namely, (i) whether a disputed bitemark issufficiently detailed and (ii) whether forensic odontologistsand other practitioners in the criminal justice system areprofessionally trained to handle the said bitemark. Due tothe hostile nature of the environment in which bitemarksare produced on human skin, such bitemarks may notbe sufficiently detailed and any findings made from itsexamination shall be highly unreliable and prejudicial.However, if the disputed bitemarks are sufficiently detailed,then professionally trained forensic team can make all thedifference between justice and injustice.Therefore, selected police officers must be given abasic training in the field of forensic odontology so that theywill be able to appreciate the evidential value of bitemarkand contribute to the development of bitemark cases inMalaysia. The relevant authorities governing the dentalpractice in Malaysia should standardize the methodologyand terminology used in bitemark examination and in thereporting of its findings so that confusion and inconsistencyamong the forensic odontologists are kept absolutely low.Finally, forensic odontologists must be given specializedtraining in bitemark examination so that the probativevalue of their findings can be improved.ACKNOWLEDGMENTThe authors thank Professor Dr. Kasinathan Nadesan(John Hunter Hospital, New South Wales); Dr. Iain Pretty(University of Manchester); Dr. Michael Bowers (Diplomateof the American Board of Forensic Odontology); Dr. Hjh.Noraini Nun Nahar Hj.
