Teeth have become smaller as our brains have increased in size

Fri

New research has shown that human teeth have decreased in size as our brains have become larger over the last 2.5 million years. Researchers in Spain have described the finding as an ‘evolutionary paradox and suggested that the changes could have come about due to drastic alterations in diet. The study involved a variety of primates and revealed that humans are the only ones who have smaller teeth in relation to brain size.

Previous ideas about human evolution would suggest that mankind needed to eat more to support a growing brain and higher metabolism, which would in turn lead to larger teeth; however, experts believe that as humans started to eat more nutritious foods, like animal meat, this enabled the same amount of proteins and fats to be absorbed without the need for a greater quantity.

Lead researcher Juan Manuel Jimenez-Arenas, wrote in the research article that ‘Brain volume and cheek-tooth size had traditionally been considered as two traits that show opposite evolutionary trends during the evolution of Homo. Here we show that there is an essential difference between the genus Homo and the living primate species.’ It was also revealed that humans are the only primates to show an ‘inverse relationship’ with teeth and brain size, compared to other primates. The shrinking of the teeth could possibly be a genetic change, based on the inactivation of a gene called MYH16 – which is linked to brain structure.

Victoria Beckham has not had Botox says skin doctor

Thu

According to her dermatologist, former Spice Girl Victoria Beckham has never used Botox or fillers to improve her appearance, although she has admitted to the use of cosmetic surgery in the past to boost her bust and then reduce it to a more natural size. The 39-year-olds skin specialist Dr Harold Lancer told The Daily Mail that the singer suffered with acne and skin blemishes when she was younger, but had improved her lifestyle and beauty regime over the years, to see an impressive change in her complexion.

Dr Lancer said ‘Victoria Beckham is a natural beauty. She’s an incredible health nut – she watches her diet, her exercise, she sort of leads an ideal healthy lifestyle.’

The mother-of-four recently revealed to Allure magazine that she gets up at 6am every day to run four miles, in order to keep herself in good shape, she also opened up about her skincare routine and talked about how happy she was when living in LA with her husband and four children.

Her dermatologist, who is based in Beverly Hills, when on to say that ‘She’s an example of how skincare products can be used to convince tissue to heal itself from outside in and the inside out. She suffered badly from acne but [her skin now] is totally self-resolved. She pays meticulous attention to product use and lifestyle. And I supervised all of it so I assure you nobody has touched her with any surgical implements of lasers. She’s an example of self-discipline.’

Former TOWIE star Lauren Goodger denies further surgery

Wed

Reality regular Lauren Goodger recently admitted to having a breast augmentation for ‘personal’ reasons but the former TOWIE (The Only Way Is Essex) cast member has denied any further plastic surgery and she has addressed the rumours in her recent New! magazine column.

The 28-year-old has said that she does not want to have Botox or liposuction any time soon and doesn’t feel that she needs it right now. Lauren says in her column ‘There was a story last week claiming I want more surgery, but it couldn’t be further from the truth. If I did want lipo, I could have it done, but I want to do things the healthy way.’

Lauren has struggled with her weight after her time on TOWIE forced her appearance into the spotlight of reality TV; although she seems to have been working hard lately to improve her health. She writes ‘I feel a lot slimmer this week. I’ve noticed my stomach looks a lot flatter. I’ve stuck to my diet.’

Thanks to her hard work and surgically enhanced bust, Lauren is feeling much more confident in her appearance and has denied that she has undergone facial injections to improve her complexion, saying ‘I’ve never had Botox and I don’t think I need it. I feel confident in myself.’

Mary Berry hits out at anti-wrinkle treatments

Thu

TV baker Mary Berry has spoken about anti-wrinkle treatment and aging gracefully as she collected the ‘Oldie of the Year’ award for 2014. Mary – famous for her work on TV show The Great British Bake-off – has hit out at cosmetic procedures such as Botox injections or face lifts, and even said that she would not use anti-wrinkle cream to try and halt the aging process.

After accepting her trophy at the Oldie of the Year awards 2014, Mary admitted that she ‘loves being an oldie’ and commented that everyone should feel that way, saying ‘There’s no Botox, and there are no implants and no tucks and wrinkle smoothing. I don’t have any beauty regime, not at all.’

The TV judge went on to say she has never used face creams and preferred to rely on a simple routine of one foundation, powder, lipstick, and nothing else, adding ‘I don’t want expensive make-up. Why bother?’ Mary also described how she undertakes a healthy diet but does not cut anything out, she said ‘Eating well is important but I don’t go in for sugar free diets. You should have a little bit of everything. I will always eat cake. I think it cheers you up. Have a small slice, not too often, and don’t go back for seconds.’

Nuts gave Stone Age man toothache

Thu

According to new research revealed by scientists at the London Natural History Museum, Stone Age man suffered toothache from consuming a diet of acorns and pine nuts. Teeth were taken from 52 skeletons dating back over 13,700 years and they showed evidence of decay, with only three of those examples cavity-free.

The hunter-gatherers had to feed themselves before farming became the norm and scientists believe that the dependence on a diet of wild acorns and pine nuts brought about dental problems for early man. Both products contain high levels of fermentable carbohydrates that can cause decay if they are not cleaned away from the teeth after eating; they lodge themselves between the teeth and attract oral bacteria.

Stone age men are also believed to have lived a sedentary lifestyle due to a reliance on wild nuts; researcher Isabelle De Groote, from the Museum, said ‘These people’s mouths were often affected by both cavities in the teeth and abscesses, and they would have suffered from frequent toothache.’

The skeletons used during the research were recovered from a cave system in Taforalt, Morocco, where numerous Stone Age remains have been located. Charred samples of food were also found and palaeobotanist Dr Jacob Morales explains that ‘We use charred fragments to identify plants that were carried back to the cave, including food items, such as acorns and pine nuts, and grasses that were used to make baskets.’

Study finds that soft drinks are as bad for teeth as drugs

Mon

A study carried out in Philadelphia has revealed that excessive consumption of soft drinks – even diet versions – can be as damaging to the teeth as dangerous narcotic, such as crystal meth; although the amount of soda required to do the same damage is said to be much more than the normal amount consumed by the average person.

Dr. Mohamed Bassiouny, who carried out the research at the Temple University School of Dentistry in Philadelphia, compared a patient in her 30’s that drank two litres of soft drink every day for five years, to a 29-year-old meth addict and a 51-year-old crack-cocaine user. The meth addict also admitted to drinking two or three cans of soda a day and the crack user said that they had regularly used the drug for 18 years; furthermore, the soda drinker added that she had not been to see the dentist in many years.

Dr Bassiouny told U.S News and World Report that ‘None of the teeth affected by erosion were salvageable’; he found that all of the test subjects had to have all their teeth removed due to their poor condition. Additionally, the study found that sugar-free soft drinks are just as damaging to the teeth as the regular version, due to their acidic content.

The American Beverage Association felt that the research was flawed and said ‘The woman referenced in this article did not receive dental health services for more than 20 years – two thirds of her life, to single out diet soda consumption as the unique factor in her tooth decay and erosion – and to compare it to that from illicit drug use – is irresponsible.’

Dental treatment costs more in Glasgow that anywhere else in the country

Fri

According to new statistics released by the Scottish Government, people in Glasgow are costing more money than the rest of Scotland when it comes to dental treatment – approximately £57 for adults and £73 for children in the last year. NHS Ayrshire and Arran came in second, with around £52 for adults and £71 for children. The cheapest place for tooth care was Orkney, spending as little as £23 on adult dental treatment.

Experts say that the dramatic difference in price is probably caused by poor diet in some areas of Scotland, along with a lax attitude towards oral hygiene; overall, people who fail to brush their teeth or teach their children good hygiene habits cost the NHS almost £260million last year. Clinical director for the Scottish Centre for Excellence in Dentistry, Arshad Ali, said that it was important for parents to set a good example with dental hygiene; he said ‘In areas with higher levels of deprivation, such as Glasgow, information shows that dental health is poorer. Poor dental health is very much related to diet and frequency of tooth brushing. It is important that people brush regularly with fluoride toothpaste and for parents to pass on good advice to their children.’

Mr Ali also added that any symptoms of dental problems should be addressed quickly, saying ‘It is important to get treatment early. You will get parents who bring children in at the first sign of a problem and other wait till their children are in real pain. At this point, the cost of treatment will be higher.’

Richard III skeleton reveals lifestyle and cause of death

Thu

Researchers studying the bones of the last English monarch to die in battle have revealed that damage to the jaw and skull supports recorded evidence that Richard III was killed with blows so heavy that they drove the crown into his head. Dental examination also showed that the king may have been as nervous as he is portrayed to be by Shakespeare; his teeth were ground down by stress and there are signs of tooth decay.

In a paper written for the British Dental Journal, Dr Amit Rai detailed that Richard was ‘likely to have been killed by one or two blows to the base of the skull’ after riding into battle wearing his crown. King Richard died during the Battle of Bosworth in 1485 and his remains were missing until last year, when they were found under a council car park and DNA analysis confirmed the skeletons identity.

As well as tooth decay, Dr Rai said that the monarch’s teeth and jaw showed signs of medieval dentistry, possibly needed because of a rich diet of carbohydrates and sugar, which the royal family would have enjoyed. The back teeth and upper right teeth had suffered some surface loss, suggesting Richard had stress-related bruxism – although the exact cause of this condition is not clear. Dr Rai also documented evidence that the king had undergone dental surgery and had two teeth extracted, noting that ‘Analysis… will enable the identification of the strains and diversity of bacteria which once inhabited Richard’s mouth and provide a better insight into this diet and oral hygiene habits.’

Blackberries may help fight dental problems

Mon

New research published in the Journal of Periodontal Research suggests that the antibacterial properties contained in blackberries could help prevent or at least help with the treatment of gum disease. When compared to other berries, it was revealed that blackberries contain the most antioxidants that have been linked to blocking the spread of cancer cells – which could mean that they also assist with the prevention of oral cancer.

Nigel Carter OBE, Chief Executive of the British Dental Health Foundation said that this backed the theory that a good, balanced diet benefits all aspects of health. He commented that a healthy diet full of vitamins, minerals, and fresh product can offer a high level of anti-oxidants to help in the fight against numerous ailments, including gum disease and oral cancer – he even added that a New Year’s resolution involving diet improvement would be a good way to start 2013.

Dr Carter went on to say that; ‘Although the study is promising, it is important that any use of blackberries in preventing and treating gum disease should be as well as maintaining a good oral hygiene routine. Prevention is a really important word when it comes to oral health and it is fairly easy to keep on top of. It does not take up too much time or a lot of money, yet it is surprising how many people actually forego basic oral hygiene principles, including brushing for two minutes twice a day.’

Britney Spears denies claims of bad oral health

Tue

It’s fair to say that child star Britney Spears has had her fair share of problems in recent years, and just as it looks like she’s put her troubles behind her, US gossip magazine National Enquirer has published a story claiming that the mother-of-two has bad breath, due to her extreme diet. Representatives of Spears have come forward to deny claims that were quoted from an unknown source, saying that ‘Britney’s breath absolutely reeks!’

According to the source, it’s the pop-stars diet that is causing the decline in oral health, as they added that ‘It must be the acids in her tummy or something from this crazy diet she’s on because her breath will start smelling twenty minutes after she brushes her teeth.’ Her meal plan has been described as ‘absolutely brutal’ including egg whites, whey protein shakes and lean meats, as she attempts to keep in shape for her role as X-Factor judge in the US. This combination of foods can apparently cause halitosis by ‘producing breath-affecting by-products or ammonia in the body.’

There doesn’t seem to be any evidence to support this other than rumour and hearsay, and Internet site Gossip Cop has reported that Britney’s people are saying the rumours are ‘not true’; they have also denied that the so-called source is a friend of hers or has ever even met the star.
