- James Field added an answer:1Is it possible for human cells to be in absolute contact with fully mineralized tissue and stay alive and active for long time periods?
For odontoblasts even a tiny amount of predentin (organic, not calcified) is essential to their survival. Please provide ref. sources. Thanks in advance
Hello Leonidas - I would say that the answer is yes. Although this is not my area of expertise, we have a number of bioactive mineral restorative materials such as MTA and Biodentine that are bio-inductive and support contact with pulpal and periodontal tissues and even initiate regeneration.Following
- Maria G H Biazevic added an answer:1What is the name of this formula and can you help me with a way to calculate it?
This is the formula utilized to determine the diversity of dental patterns (a forensic odontology method) through pairwise comparison of a sample, i cannot find its name and a way to calculate it; i have calculated the diversity by using the Simpson Diversity Index but i have my doubts concerning the comparison with the diversity values in the scientific literature (all studies utilize the aforementioned formula). All comments will be very welcomed.
We created the formula using the diversity patterns of the Brazilian population.Following
- Abhijeet Alok added an answer:3How can CBCT be used to assess the volume of pulp in 3D, as a forensic tool to estimate age?
One of the most important issue in a forensic science is age estimation which can be assessed through different skeletal factor and dental marker and among dental issue decreasing size of the pulp due to continuous dentin deposition through out the life can be considered important forensic tool for age estimation, I will ask of application of CBCT to evaluate pulp size from coronal to end of pulp canal in a three dimensional view and correlate it with real age with regards

- Laura González-Garrido added an answer:10Which method/process would you consider to be more accurate in determining dental caries in archaeological skeletal remains?
Is Hillson (2001) dental caries assessment too much extensive and complicated method? or, to the contrary; Are the other assessment methods superficial and incomplete and mistaken in root caries? for example, Kerr (1988)?.
Thanking you in advance. Laura.
I´m waiting for to use X-ray before issuing an exact diagnosis.
- Dr. Umamaheswari T.N added an answer:7Is there any forensic odontologist who had tried lip prints as a biometric tool?There are many situations where fingerprints alone cannot be used as a biometric tool.

- Ibrahim Cakir added an answer:4How can we make a positive or personal identification from tooth caries?
I want to know how to achieve a positive identification of an individual regarding forensic odontology and forensic anthropology. Concisely, positive identification of the victim from tooth caries and the ways to determine perpetrator.
2. Can anyone suggest to me an article about these issues?
Thank you all for the reply. have a question to Mr. Sandholzer. You wrote tooth caries is a dynamic process.
1)if the caries is active before death, can it continue after death for a while?
2. For example, a man has been to a dentist and had a radiograph of his teeth, he has several tooth caries lesions from beginnig to groos lesions,
So How many time should be passed to make comparison correctly after his death?Following

- Laura González-Garrido added an answer:9Which could be the best standard method to use in an enamel hypoplasia formation ages study?According to some authors, different methods produce different results, thus it is critical to decide which method to use. I have a dilemma: Goodman and Rose, 1990? Goodman and Song, 1999? Reid and Dean, 2006? Or do I use everyone?
Thank you so much John for this recomendation, I got the full paper Cheers.Following

You are welcome!
Have a good work.

Our article published in peer-reviewed Journal "Communicative & Integrative Biology". A few major points discussed in the paper:
(1) Brain is not the source of consciousness.
(2) Consciousness is ubiquitous in all living organisms, starting from bacteria to human beings.
(3) The individual cells in the multicellular organisms are also individually cognitive entities.
(4) Proposals like “artificial life”, “artificial intelligence”, “sentient machines” and so on are only fairytales because no designer can produce an artifact with the properties like internal teleology (Naturzweck) and formative force (bildende Kraft).
(5) The material origin of life and objective evolution are only misconceptions that biologists must overcome.
About Forensic Odontology (Forensic Dentistry)
This group should encourage discussion of latest results in forensic odontology/forensic dentistry. Moreover, it should be a platform to announce upcoming meetings/conferences/workshops in this & related fields.
