The challenge of unidentified decedents in Africa: The need for training and research in forensic odontology to strengthen a multidisciplinary approach.

Introduction: The management of unidentified decedents suspected to be undocumented migrants is a growing humanitarian crisis in Africa. Identification of the dead and the right of the family to know the fate of a decedent is a fundamental human right. Forensic odontology methods can provide helpful and assisting information in the identification even in challenging low-resource settings. South Africa and other countries that are part of significant migration routes face the problem of unidentified decedents. Discussion: The fundamental application of forensic odontology relies on the availability of good antemortem dental records. The state of dental records was reported to be suboptimal in South Africa and other African countries. Incorporating forensic odontology into the undergraduate training in the 23 dental schools in Africa will increase the understanding of the value of maintaining accurate dental records and potentially facilitate collaboration with dentists and forensic odontologists in cases where dental features can be used for identification. South Africa offers postgraduate training in forensic odontology, and prospects for research in Africa need to be explored. Conclusion: The development of a forensic odontology career path and research prospects will provide African countries with the potential for building multidisciplinary teams to assist in solving the challenge of unidentified decedents.

The genetic determinants of oral diseases in Africa: The gaps should be filled.

Oral diseases are a major health concern and are among the most prevalent diseases globally. This problem is becoming more prominent in the rapidly growing populations of Africa. It is well documented that Africa exhibits the most diverse genetic make-up in the world. However, little work has been conducted to understand the genetic basis of oral diseases in Africans. Oral health is often neglected and receives low prioritisation from funders and governments. The genetic determinants of highly prevalent oral diseases such as dental caries and periodontal disease, and regionally prevalent conditions such as oral cancer and NOMA, are largely under-researched areas despite numerous articles alluding to a high burden of these diseases in African populations. Therefore, this review aims to shed light on the significant gaps in research on the genetic and genomic aspects of oral diseases in African populations and highlights the urgent need for evidence-based dentistry, in tandem with the development of the dentist/scientist workforce.

Fibrodysplasia ossificans progressiva (FOP) in South Africa: dental implications in 5 cases.

Fibrodysplasia ossificans progressiva (FOP) is a severe genetic disorder in which progressive ossification of subcutaneous tissues leads to immobility and profound physical handicap. Dental management of affected persons may be constrained by impaired mobility of the temporomandibular joints. Equally, the traumatic aspects of dental intervention can exacerbate the ossification process. In the later stages of the disorder, thoracic immobility impairs pulmonary ventilation and compromises dental anesthesia. We have undertaken dental appraisal and treatment of 5 South Africans with FOP, with ages ranging from 2 to 52 years. The age relationship of the manifestations of FOP was apparent in these persons, as were the dental problems that emerged. These dental observations illustrate the importance of accurate diagnosis and the awareness of potential complications that may be encountered in dental management. Our observations are presented and discussed in this article.
