Lindsay Lohan may have had Botox to look good in her mug shots, experts have said.

Plastic surgeons have told UsMagazine.com that the actress, whose jail check-in photo has been widely circulated around the internet, could have had several cosmetic procedures.

Dr Kenneth Beer, owner of the Scientific skincare line, suspected that Ms Lohan had used Botox in her forehead to reduce frown lines before her 90-day prison stay for violating probation.

He also speculated that she had had her lips injected with a filler to make them look plumper.

Chief of the division of plastic surgery at George Washington University Dr Michael Olding agreed.

“There is no question that Ms Lohan had filler of some type in her lips,” he told the online magazine after looking at the picture.

Botox and lip-fillers could even have been used because the star suspected her photo would be seen around the world, suggested dermatologist Dr Marcy Street.

Emergency dentistry information will be easily accessible with the introduction of a new app for iPhones, iPods and iPads.

It follows on from oral health website DentalOptimizer.com, which lets users to carry out risk assessments for cavities and gum problems, as well as creating an oral health profile.

Former president of the American Dental Association William Ten Pas is part of the Oregon-based company that developed the interactive website and program.

“This new dental treatment application enables consumers to have easier access to care and allows them to make better informed decisions about their health,” he said.

Patients will be talked through what dental treatments are available and tell them how to prevent common problems such as tooth and gum disease.

President and chief executive officer of Oregon Dental Service Robert Gootee said the app, which also allows patients to rate and comment on their dentists, had been launched in response to clients’ needs.

An emergency dentistry kit will go on sale in America to help with common dental problems.

The Emergency Dental Kit, produced by SciMeDent Health, contains temporary cement for lost or broken fillings, toothache drops and denture repair material.

Chief executive officer of the company Dr Jan Stahl warned that the equipment was not intended to act as a substitute for a visit to an emergency dentist.

“This kit provides safe, temporary relief until a dental visit can be scheduled,” he said.

Sports teams and school nurses like the security of having tools to deal with dental crises, the organisation has claimed, adding that many people also take their emergency dentistry kits on holiday with them or keep one at home.

A 2002 study of paediatric dental clinics found that just under half of all tooth injuries to children occurred in the home.

Dr Stahl explained that “millions” of dental emergencies occur every year at times when dentists cannot be reached.

Invisalign sales and profits have risen dramatically in the last year, new figures have revealed.

Align Technology, which manufactures the invisible braces, announced it made $32.6 million [£21.2 million] net profit in the second financial quarter, compared with just $4.3 million this time last year.

Over 50,000 cases of Invisalign products, which include Full, Express/Lite, Assist and Teen versions, were shipped to orthodontists and Invisalign dentists across North America between April and June this year, with 18,000 more being sent overseas.

Company president and chief executive officer Thomas Prescott described the results as “outstanding”.

“Our Invisalign business continues to outperform our expectations, resulting in our third consecutive quarter for record revenues and case shipments,” he added.

The cosmetic dentistry product, sold for an average of $1,415 internationally, is made up of several sets of removable invisible braces, which are replaced every two weeks to reposition the teeth.

Many children in Plymouth may find they have to go for emergency dentistry, if new figures are anything to go by.

A report from Plymouth’s NHS Oral Health Strategy has revealed that 29.1 per cent of five-year-olds suffered obvious tooth decay in 2009.

Furthermore, only 11 per cent had these decayed teeth filled, the Herald reports.

According to city healthcare experts, the problem comes as a result of poor diets and a high consumption of sugary sweets.

Dr Gill Jones, Plymouth consultant in dental public health, said many parents do not do enough to give their children’s teeth a proper clean twice a day.

“And we’ve got to get children used to coming into the dentist, giving them fluoride and brushing advice. It’s about raising awareness,” she added.

Dr Jones said that although it is fine to have some sugar at meal times, youngsters should not snack on sweet treats too much.

Earlier this week, the British Dental Health Foundation told Elle magazine that consuming too much sugar can lead to acid attacks.

Some people may require emergency dentistry because they only go for a check-up when they start to experience pain.

This is according to one expert, who said some patients are in denial about needing treatment.

Ken Schweifler wrote for the Los Angeles Town Crier that many treatable ailments, such as dental decay and periodontal disease, do not have any obvious symptoms.

However, modern technology such as X-rays means they can be detected straight away, thus avoiding the need for emergency dentistry.

“Today’s dentists are highly trained to identify problems in their earliest stages and render technically demanding treatments that conserve tooth structure and prevent tooth loss,” Mr Schweifler added.

He said that until recent technological developments, pain was the only indication of a serious dental problem.

Writing for the Daily Express, Dr Rosemary Leonard recently said that although drinking fruit juice is healthy, too much may lead to tooth decay and damage enamel.

A new type of Botox treatment is being developed that may eliminate the need for needles to administer the drug, it has been claimed.

Revance Therapeutics says clinical trials of the solution may be completed in two years before authorities decide whether or not to approve it.

The Orange County Register reports that patients who used the drug, called RT001, saw a reduction in the wrinkles around their eyes after a month of application.

However, Dr Richard Glogau, clinical professor of dermatology at the University of California, said more work needs to be done to the Botox-like treatment to ensure it does not spread to other parts of the body once it has been put on the skin.

Dr Fredric Brandt, a dermatologist from Miami, said: “The results are good, but they probably won’t be as dramatic as [Botox] injections.”

Meanwhile, a study by the US Association for Psychological Science recently found that because people who have had Botox are less able to frown, unhappy feedback cannot be sent to the brain, which makes them feel more positive.

Anxiety can mean some people end up needing emergency dentistry, it has been suggested.

Writing for the Los Angeles Town Crier, Ken Schweifler described how a negative experience in the dentist’s chair can lead to fears about going for a check-up.

However, he said this may turn into a catch-22 type of situation.

Because people are anxious about receiving treatment they do not visit the dentist on a regular basis, meaning they miss out on preventative maintenance, Mr Schweifler explained.

This leads to more serious problems and, as a result, they require emergency dentistry.

“This traumatic experience then reinforces the dental phobia,” he added. “They never experience the rewards that come with uneventful checkups and achieving dental health.”

Children also require regular check-ups and nvdaily.com recently reported that according to the American Academy of Paediatric Dentistry, youngsters should go to the dentist before they are one year old.

People should make sure they only receive Botox treatments from professionals in order to lessen the chances of something going awry, one expert has suggested.

Dr Jennifer Ashton told CBS News that the procedure does have a number of benefits and can be helpful in reducing the appearance of fine lines on the face.

She remarked: “There is a sweeping trend, kind of an undercurrent thinking that if you hit those wrinkle areas before they actually have time to form, you’re literally preventing wrinkling.”

However, Dr Ashton stated it is still important to promote the idea of beauty coming from within.

In the US, around 26 per cent of women who have received injections to slow ageing are in their 20s or younger, she explained.

Her comments come just days after a study by the US Association for Psychological Science found Botox can make people happier, as reducing the ability to frown was shown to raise spirits.

Dental implants could soon be grown in the mouth using stem cells, according to a researcher from an American university.

The process, designed by the Tissue Engineering and Regenerative Medicine Laboratory at Columbia University Medical Centre, would allow patients to regrow a tooth in as little as nine weeks.

Using stem cells, the technique creates a three-dimensional scaffolding system in the tooth socket.

The scientist behind the new technology, Dr Jeremy Mao, said it could be a cheaper alternative to dental implants and more reliable and long-lasting as the regenerated teeth would completely integrate with the surrounding tissue.

Stem cells are able to grow into many types of human tissue and are often capable of renewing themselves indefinitely, according to the US National Institutes for Health.

His study, published in the Journal of Dental Research, outlined a course of action that is quicker than traditional tooth implants, which can take up to 18 months to heal completely.
