My last blog was at Christmas and I’ve been meaning to do another one for the last few weeks but never seemed to get around to it – so here it is finally!
Since the Christmas break (which was lovely and lazy!) and settling back into work I’ve really started to get going with my project. The first step of my project was to propose an adjusted method for recording dental wear in human molars, which was completed before Christmas. This also included identifying the aging method, using human dentition, that would most be the most accurate and easy to apply and came to the conclusion of using the AlQahtani et al (2010) London Dental Atlas. About 2 years ago I wrote another blog piece discussing the accuracy of three different dental age estimate charts, including the London Atlas. The article describes the AlQahtani et al (2010) method in brief but the atlas itself can be viewed here.
The next step was to test out the method that I had created to assess how it worked when practically applied to human skulls. In order to do this I needed a good skeletal collection of the correct time period for my project (neolithic to medieval) that included juvenile and adults skulls. Luckily for me there is such a collection at Southampton and so it was very easy for me to get started! You can find out a bit more about the teaching collection and courses that Southampton University at the following blog: BOS, curated by the wonderful Ellie!
So it’s now the beginning of February and I’ve managed to apply my method to the juvenile skulls twice and the adults once. My plan is to do this a few more times for each set of skulls and there are a few reasons for this. The first is that this will enable to tweek my method where necessary so that it is as easy and accurate to use as possible. The second reason is so that I can become comfortable with handling and identifying teeth, but also so that I get used to the process of recording the data. This will be particularly useful when I move on to different skeletal collections, where I will only have a short period of time with them.
Finally, and probably most importantly, recording the data from the same set of skulls, multiple times will allow me to test the repeatability of my method. In order for this method to be robust and accurate it must produce statistically similar results when applied to the same collection, this will ensure that any results obtained using this method can be comparable. When recording the data from the same collection of skulls I am making sure that there is a period of time in between each data collection. This ensures that I cannot remember any particular individual and all of the collected data is ‘new’ again.
So far, the data collection is going well and I am getting through the skulls in the time that I wanted. Another key aspect of my project is to produce a method that is quick and easy to apply, and at the moment that’s going to plan so fingers crossed it stays that way!
I probably won’t do another blog post on the progress of my PhD for a little while as I won’t have much new to say until I’ve finished my data collection. However, I do plan to do a new blog post on molar identification (seeing as I’m getting pretty good at it now!). Hopefully, I’ll sort that out soon and get it posted!
