Space Orcs

I had to hop on this bandwagon

Imagine you're an alien, and you learn that getting bit by a human can cause serious infection and disease and stuff.

Then you learn about dentists, whose whole job is to clean humans' freaky mouth-bones with tools that could be easily confused for torture weapons. And humans pay for this?! YEARLY?!

And then...AND THEN you learn that some humans have spit that is so acidic that it can actually damage their teeth.

And what do humans do to show affection? MIX THEIR SALIVA TOGETHER! Are they making deadly venom? Are they that desperate for affection that they're willing to risk their health?

WHAT ARE HUMANS ANYWAYS?!

Forensic Odontology Overview

Forensic odontology is a subspecialty of dentistry that has its main focus on the identification of deceased victims. In simplest terms, there are two aims in forensic dentistry. The first one is the identification of the dead, and second is the identification of an assailant who has used his or her teeth as a weapon. But how? Let's see.

Let's start with corpse identification. Teeth can be used to identify corpses, as no two oral cavities are alike, and teeth are unique to an individual. The dental evidence of the deceased recovered from the crime scene is compared with ante-mortem records for identification. This is used in cases such as mass casualties, burn victims, or severely disfigured/decomposed corpses.

Forensic odontology can also be used to determine things like age, race, and sex. In cases where there is no blood or other DNA sources, teeth can also be used.

Age is determined by looking at X-rays of the permanent teeth and tooth roots within the bone. The crown of a tooth forms first, followed by the root, and scientists estimate age by comparing the stage of tooth formation in the X-rays and bone with known dental growth standards.

Race is found by comparing the shapes of the different teeth. Determining race using teeth isn't easy, but using common dental characteristics as indicators (like Caucasoids usually having narrow “v-” shaped arch giving rise to crowding of teeth) we can get a good guess.

To determine sex, we rely on sexual dimorphism. Generally, male teeth have significantly greater quantities of dentine than females, while female teeth are found to have greater enamel thickness than male teeth. This isn't always fully accurate, but when combined with other factors, it helps give an idea.

None of these are perfect, but they can help give us a good approximate description, which is better than none.

Now, Bite Mark analysis.

There's 4 steps to bite mark analysis. Photographs, saliva swabbing, impressions, and tissue samples.

In order to make a good comparison, a balanced, color, scale photograph should be made of the defendant’s teeth (which can be used for testimony in court) and of the victim’s bite. Because the dental expert will need to know the scale shown in the picture, some method of measurement (such as a ruler or tape measure) photographed alongside the bite mark and the defendant’s teeth is necessary. A plaster cast of the defendant’s dental impressions can also be used to prepare a plastic overlay. The plastic overlay is used to mark the points of contact and forms a representation of defendant’s bite marks or a pattern of the cutting edges of defendant’s teeth. This representation can then be compared with a scaled photograph of the bite mark on the victim as a means of determining common points of identification.

If the bite area was swabbed and saliva recovered, and it was a positive match to the subject, that could help identify the assailant, but it's not often that DNA can be recovered.

Bite analysis has its issues, as tooth marks are not always transfered accurately, and sometimes there's not enough difference in bite marks to tell reliably. Bitemark analysis is more often used for excluding someone as a potential assailant. Say the mark shows imprint of fully intact frontal incisors, and the proposed biter does not have all their front teeth. This means that the person being accused is not the probable assailant. This could also be used to tell if the bite was self-inflicted. But bite mark analysis is often not admissible due to it having been found to be unreliable in some cases. People have been rightly and falsely convicted because of it, and it can be an unreliable method for forensic examination.

As with all areas of forensics, it's under dispute for its reputability. Bite mark analysists have been shown to be unable to consistently agree on whether the bitemark was even human. Even minor distortions could lead to the mark matching a number of people.

And here's a little bit of interesting history I came across in my travels :)

There are many "first" uses of forensic odontology in history across the web, but as far as I can find the first documented use of teeth for identification began during 66 AD, with the Agrippina and Lollia Pauline case. (There's a bit to it, find it here.)

Recorded forensic identification in India started in 1193, where Jai Chand, a great Indian monarchy, was destroyed by Muhammad's army, and Jai Chand, Raja of Kanauji was murdered and he was identified by his false teeth.

Dr Ascor Amoedo is reputed as the father of forensic odontology and documented the first case of dental identification in which many individuals lost their lives in a disaster. 126 people were charred to death due to a fire accident in Paris 1897, and were identified using their teeth.

In 1979, a double bite mark played an important role in convicting Ted Bundy of murder as he'd bitten one of his last victims.

At the dentist with a big ass bar of chocolate in my hoodie pocket like he's going to say "do you eat a lot of sugar?" while I make direct eye contact and take a huge bite of Cadburys Dairy Milk.

Very fascinated by all sorts of specialised tools n doohickeys, so every time I go to the dentist, I worry that I might seem TOO STOKED to be there, you know? That I might seem kinda like that guy from Little Shop of Horrors ... which I think is very interesting thing to worry about while at the dentist.

#thoughts #dentists #ooh what does this do #if a profession has specialised tools im stoked about it #and i dont think dentists specifically get too many people who are like whoah COOL DRILL #:D #tell me all secrets of your trade

Post-canon Akeshu reunion where dental hygienist Goro Akechi walks into the patient’s room and sees Akira Kurusu in the chair. Cue poorly explaining why he stayed away while cleaning Akira’s mouth until Akira just bites his fingers. It’s okay, he can show off his pearly white smile to his previously presumed dead rival turned hopefully boyfriend, which is a lovely smile by the way! Hey Crow, you missed out on this cute lil grin for AGES. This is great, but you’re still getting bitten—

Akechi: Your gums wouldn’t be bleeding so much if you flossed more. Akira: Oh, I bet. Maybe my cognitive self wouldn’t have bled so much when you shot me if I had flossed more back then, too! Akechi: Listen here, you little shit. Akira: Alright, whatever. Swapped out the leather gloves for latex? Akechi: Standard sanitary procedure, Joker. Akira, fishing a certain glove out of his pocket: Wanna try this one on for old time’s sake? Akechi: …You still carry it with you? Akira: I carry your glove, the weight of your loss, and all this dental plaque. :D

just remembered that time I went to the dentist for the first time in a while and first she got annoyed because i wouldn't take my nose ring out, and then she told me i had no less than six (6) cavities.

That's weird, 20-something-year-old me thought, since I have never had a cavity before and nothing about my diet or oral care has changed. Also, aren't cavities supposed to hurt, kinda? At least one of these six cavities should be causing me problems, right? Anyway I did not sign the forms that would allow her to give me six fillings + anaesthesia and whatever else they do for cavities, so I let her do just the cleaning and left.

A couple days later, still wondering how the hell I'd managed to not notice SIX CAVITIES I decided to get a second opinion. A friend recommended a different dentist to me and I figured that he could fill in these six cavities for me.

Anyway, you can probably guess where this is going. I went to the different dentist who did not say shit about my nose ring, and said I did not, in fact, have six cavities, but uh, zero.

Anyway, dentists are not exempt from medical malpractice and if something feels weird to you GET OUT AND GET A SECOND OPINION.
