Q: It was with a force greater than an atom bomb that Mount Vesuvius erupted and blotted out Pompeii in 79 A.D. Or, not blotted out, exactly. The city’s destruction, and the thing that has kept Pompeii so fascinating over the centuries, entails a paradox: The surge of ash and hot gas that blanketed thousands of victims also, simultaneously, preserved their bodies—along with their colorful art, sparkling jewelry, wine jugs, scrolls, and other cultural remnants. Now, scientists are using new imaging technologies to examine in detail the bones and teeth of those killed in the blast. Detailed casts of Pompeii’s victims—made by pouring plaster into the small cavities in their ash-encapsulated remains—have long prevented sophisticated scanning of this nature. The 19th-century plaster is so dense that today’s standard imaging technology can’t distinguish between the thick outer cast and skeletal pieces inside. But researchers recently used a multi-layer CT scan to obtain imagery never before possible, then used software to make digital 3-D reconstructions of skeletons and dental arches. 
  
 The initial images reveal two major surprises. For one thing, these ancient people had “perfect teeth,” according to Agenzia Giornalistica Italia, a discovery that scientists linked to a healthy diet and high levels of fluorine in the air and water near the volcano. ANSA The scans also support a theory that many of those who were killed after the eruption died from head injuries—caused by falling rock or collapsing infrastructure—and not from suffocation. This squares with the famous account by Pliny the Younger, who wrote of his uncle’s death after the eruption in an account that is treasured by historians. Here’s a portion of one of Pliny's letters, translated from Latin by Betty Radice: They debated whether to stay indoors or take their chance in the open, for the buildings were now shaking with violent shocks, and seemed to be swaying to and fro, as if they were torn from their foundations. Outside on the other hand, there was the danger of falling pumice-stones, even though these were light and porous; however, after comparing the risks they chose the latter. In my uncle's case one reason outweighed the other, but for the others it was a choice of fears. As a protection against falling objects they put pillows on their heads tied down with cloths. The smoke and ash that poured out of the volcano was likely still stifling to those who experienced it. In the early 1990s, when researchers uncovered the first remains found at Pompeii in many decades, archaeologists determined that some of the victims had tunics wrapped around their mouths as make-shift masks. Pliny the Younger described victims surrounded by broad sheets of flame, the air reeking of sulphur and the sky darker than night. ||||| (AGI) Naples, Sept 29 - A multi-layer CAT scan on 18 of Pompeii's body casts revealed that the victims of the disaster had perfect teeth - barring cavities and other pathologies that can only be revealed with different medical examinations - and fractured craniums. The analysis of the casts, which were restored in August, therefore debunks two long-held myths on ancient Romans. The findings support the inhabitants of the merchant city at the foothill of Mount Vesuvius had no immediate discernible need for dentists and likely died from head injuries caused by crumbling roofs or walls during volcanic event in 79 AD rather than suffocation. The 16-layer machine was loaned by Philips Healthcare and also gathered data on the casts of two animals, most likely a dog and a boar. 
  
 "This project offers an infinite range of approaches to researchers," Giovanni Babino, the radiologist in charge of the scans, told AGI. "From an analysis of the inhabitants' lifestyles or their teeth or other medical factors, to reconstructing the history of the casts themselves and the restoration work they have undergone." The multi-layer scans were carried out by the special superintendency on Tuesday morning through an MX16 machine equipped with a 5.0 MHU CT tube, producing 3D volumes which, through post-processing and specific software and hardware wanted by Babino, will allow a 3D reconstruction of the casts' skeletons and dental arches to be made. The superintendency also plans to create a database for researchers to use, providing a 'fingerprint' of the casts, which now evidence years of interventions to reinforce the plaster through wood and metal. Many of the casts were made in the 19th century. The examination of the teeth, overseen by specialised dentist Elisa Vanacore, was also crucial for archeological reasons, as it provided information on the victims' lifestyles and on their age and gender. The casts were of men, women and a child. They were selected among the 86 casts restored this summer, 20 of which were then displayed at the Pompeii dig site. They are also being scanned by lasers to produce 1:1 scale replicas in polymers derived from corn starch. (AGI).

  ||||| They may have lived in an era when dental care was rudimentary at best, but the ancient Romans had better teeth than people today, new research has revealed. 
  
 Scientists used CAT scans to examine the remains of 30 men, women and children who were killed in Pompeii when the city was engulfed by ash and pumice from Mount Vesuvius in AD 79. 
  
 After months of research, their most startling discovery was the excellent condition of the Romans’ teeth, which the researchers ascribed to a low-sugar, fibre-rich Mediterranean diet. 
  
 “The inhabitants of Pompeii ate a lot of fruit and vegetables but very little sugar,” said Elisa Vanacore, a dental expert. “They ate better than we did and have really good teeth. Studying their teeth could reveal a lot more about their lives. ” 
  
 They were strangers to toothbrushes or toothpaste, but their healthy diet meant that few of the Romans suffered from cavities, the CAT scans showed. 
  
 Three-dimensional imaging revealed that many of the victims of the eruption had severe cranial injuries caused by falling masonry and rubble as homes, taverns and public bath houses toppled around them. 
  
 The scans reveal the victims’ skeletons in stunning detail, including that of a little boy. 
  
 “Their diet was balanced and healthy, similar to what we now call the Mediterranean diet,” said Massimo Osanna, the director of the ancient site near Naples. 
  
 “The research is a big step forward in our understanding of the Roman world. “Exceptional findings are emerging about their age, sex, social status and dietary habits.” 
  
 Another surprising discovery was that the bones showed deterioration as a result of the high levels of fluoride in the water that supplied Pompeii. 
  
 The research project has brought together an expert team of Italian radiologists, archaeologists, orthodontists and anthropologists. 
  
 It is not only humans that they studied – there was also a dog and a wild boar, both trapped in the conflagration that devastated Pompeii and neighbouring Herculaneum when Vesuvius erupted. 
  
 When waves of blisteringly hot ash fell over Pompeii, many people suffocated and were buried. The ash gradually hardened into pumice, encasing their bodies.

 Over time the soft tissue of the bodies rotted away, leaving cavities containing just their skeletons. 
  
 Archaeologists in the 19th century pioneered the technique of pouring plaster into the cavities. 
  
 Once the plaster hardened, the archaeologists chipped away at the surrounding pumice to extract detailed casts of the victims, many of them contorted in the moments before death. 
  
 Experts plan to examine a total of 86 plaster cast bodies. The little boy aged around four was found in a villa dubbed the House of the Golden Bracelet with the ossified remains of his parents. 
  
 Some of the remains are too unwieldy to fit into the CAT machine, including that of a woman in a sitting position who is holding a toddler on her lap, one of the most poignant casts. 
  
 Pompeii was encased in hardened ash for centuries before excavations began in 1748. 
  
 Mt Vesuvius had been spouting smoke and ash for days before it finally erupted and the majority of the population of 20,000 are thought to have fled in safety. 
  
 But around 2,000 stayed behind and were killed when ash and toxic fumes engulfed the city. |||||
A:
High-tech scans of Pompeii residents killed in the long-ago eruption of Mount Vesuvius have provided two revelations: They had amazing teeth, and many were killed by falling masonry and other objects—as opposed to the widely held theory that they were suffocated by ash. As for the first: Thank a low-sugar, high-fiber Mediterranean diet. "The inhabitants of Pompeii ate a lot of fruit and vegetables but very little sugar," a dental expert tells the Telegraph. "They ate better than we did and have really good teeth." They also benefited from high levels of fluorine in the air and water around Mount Vesuvius. The upshot was "perfect teeth," in the words of news agency Agenzia Giornalistica Italia. The CT scans were conducted on remains that had been previously preserved in plaster casts. The scans revealed that many victims had head injuries, likely from crumbling buildings. It supports an ancient account of the eruption preserved in a letter from a nephew of one of the victims, who wrote that people tied pillows to their heads to protect themselves, reports the Atlantic. Scientists are continuing to study 3D reconstructions of dental arches and skeletons, including those of a young boy, a dog, and a boar. The archaeological superintendent of Pompeii tells the Local they will eventually analyze all 86 plaster casts to discover "their age, sex, what they ate, what diseases they had, and what class of society they belonged to." (This "exceptional" discovery in Pompeii predates its destruction.)
