JC,
JC,Dear Jeffrey:
We have completed processing on the whitetail deer specimen that you submitted on November 5, 2015 for forensic aging. We promised to have the results back to you by March 5, 2016. The cementum-annuli analysis has determined that the age of “Jeff’s 2015 NJ Fall Bow Buck” is 5.5 years. Nice trophy! We will be sending you a paper copy of this result via the US Post Office. If you have any questions, or if we can be of additional assistance, please do not hesitate to contact us. As always Jeffrey, we appreciate your business. Thanks.

I have a very high level of confidence that it is, and I don't rely solely on their results. In this case, long before I got their results I did a comparative analysis of the teeth of this buck against several other sets of 3.5 and 4.5 year olds I own. All of the other sets are from other deer taken in the same general area, and all are cementum annuli aged. Several of those cementum annuli results are also confirmed by the fact that the deer were of known aged based on multiple years of trail cam pics. I concluded from my initial analysis their was zero question this buck's teeth were significantly more worn than were the 3.5s I have. So, I had no question it was 4.5 or older. When I compared the teeth to a known 4.5, again the teeth from this deer were noticeably more worn. Accordingly, I concluded on my own, based on the tooth wear and replacement method that this buck was at least 4.5 and most likely older and 5.5. Therefore, as stated previously, I have a very high level of confidence as this buck was aged by two different tooth methods at 5.5.I hope it really is legit.
The teeth aging method with whitetail is pretty accurate from birth to 3 years old. After 3 years of age, the accuracy drops in a major way to the point it's not very valid (see below).I hope it really is legit.
The percentage of jawbones and dental casts that were correctly aged by age-class is depicted in Figure 1. Eighty-five percent of the jaws and casts in the 1-2 year age class and 73 percent in the 2-3 year age class were aged correctly. Accuracy dropped dramatically in the older age classes.

EDIT: In before the same 2 or 3 posters who attack me whenever I post data from scientific studies of Whitetail arrive.
They actually have to section an extracted tooth. How much does that cost? [eek]Cementum Annulli analyzes the front lower incisors, similar to rings on a tree. I have seen it stated as being 100% accurate. I hope so.
For the hunter, I agree and have no idea why people care other than the coolness factor. But for researchers and biologists it's incredibly important.4.5, 5.5, 6.5? What's the difference? It is what it is.[wallmad]
