The applications of MicroCT in studying age-related tooth morphological change and dental age estimation: A scoping review

Conventional dental age estimation relies on destructive methods such as sectioning and staining, which are unpreferable when the tooth is required for evidential or archeological preservation. MicroCT is a non-destructive, high-resolution imaging technique that allows for accurate morphometrical measurement. Although microCT technology has been applied in a variety of dental studies, studies focusing on dental age-related change and dental age estimation based on microCT imaging remain lacking. Based on the question: “How has microCT technology been applied in studying human age-related tooth morphological change and dental age estimation studies?”, the authors conducted a scoping review in accordance with the Arksey and O'Malley (2005) and the PRISMA-ScR guidelines. A literature search using five major scientific databases identified 452 articles, with 11 full-text articles being eligible to be included in the scoping review. Furthermore, 6 out of the 11 studies performed dental age estimation modeling. An overview of the parameters used in the selected articles revealed a variety of tooth characteristics, such as pulp cavity to whole tooth volume ratio, secondary dentin, as well as the diameter of root canal orifice. The findings of this scoping review highlight the extent microCT is used in studying dental age-related changes, as well as the effectiveness of microCT in dental age estimation studies. This review serves as a guide for future forensic odontology age estimation studies.     

Ḥājji Ratan or Bābā Ratan’s Multiple Identities

This article deals with the complex personality and legacy of a mysterious saint known both as a Sufī (Ḥājji Ratan) and a Nāth Yogī (Ratannāth) and links his multiple identity as well as the religious movement originated from him, to the specific cultural context of the former North-West Indian provinces. The first part is devoted to Ratan in the Nāth Yogī tradition, the second to his many facets in the Muslim tradition, in connection with his dargāh in the Panjabi town of Bhatinda. The third and main part explores a particular movement, the Har Śri Nāth tradition. Presently centered around a “dargāh mandir” in Delhi, this movement, with its two branches issued from Ratan and from his “son” Kāyānāth, was rooted in what is now Pakistan. The influence of location and history has led to many peculiarities which lead us to stress the blurred boundaries between Islam and Hinduism and the essential part played by charismatic figures in the construction of religious identities.     

Building skills in qualitative research to inform pro-poor policy: experience from a Bangladeshi NGO

This paper describes the research methodology followed in the ‘Livelihoods of the Extreme Poor Project’, a collaborative research project in Bangladesh between PROSHIKA (a large national NGO) and DFID (the UK government department for international development). The dual purpose of this project was to learn about poor people's livelihoods and train the PROSHIKA research team in the use of qualitative research methods. The research findings were to be fed directly into policy formulation and the planning of new development interventions for the poorest people in Bangladesh. The paper provides an assessment of what the approach used achieved both in terms of building staff capacity and in policy influence, concluding that it has been largely successful in achieving its purpose.
