TV personality Peter Andre has revealed he is contemplating retrying Botox injections to prevent the development of wrinkles.

According to Now magazine, the Mysterious Girl singer has considered the treatment in a bid to reduce the appearance of signs of ageing.

"I'm thinking of Botox again. I haven't had it done for two years and I can't decide whether I like my lines or not," he revealed.

The father-of-two also claimed his disciplined exercise regime is partly responsible for his healthy physique and youthful look.

Following his split from former glamour model Katie Price, the singer has previously claimed he would be willing to allow his children to receive cosmetic surgery when they are older.

Speaking to the Daily Star, Andre revealed he would not stand in the way of Princess and Junior if they wanted to make improvements to features that had caused a reduction to their self confidence.

Health experts have spoken out against competitions that offer cosmetic procedures such as Botox as a prize.

The Independent Healthcare Advisory Services (IHAS) and the British Association of Aesthetic Plastic Surgeons are unhappy that surgery is being advertised in this way, BBC News reports.

Sally Taber of IHAS said prize draws and loyalty card schemes could encourage young people to sign up for treatments they do not need, without properly considering the consequences.

"They're enticing people to have cosmetic surgery who may not have even thought about it," Ms Taber told the news provider.

"It's important people make an informed decision in the right environment," she added.

A recent event known as My Big Fat Plastic Surgery Prize Draw offered ticket holders the chance to win plastic surgery worth £4,000.

This comes after plastic surgeon Peter Paterson told the Lancashire Telegraph that a growing number of British men are opting for Botox injections and other facial procedures to keep them looking "young, energetic and vibrant".

Researchers in Australia are preparing a medical trial to find out if Botox injections could be used as a treatment for asthma.

The landmark experiment will see botulinum toxin type A injected into the vocal cords of 30 asthma sufferers at Monash University in Melbourne.

Medical experts believe the treatment could help patients to breathe easier, as a previous study found many severe asthmatics suffer problems with their voice box as well as their lungs.

"We won't cure asthma, but it may be possible for us to relieve people's symptoms to the extent where their severe asthma turns into a mild or moderate disease," the Monash Medical Centre's Phil Bardin told the Herald Sun.

Asthma, a condition that causes tightness in the chest and shortness of breath, is thought to affect 5.4 million people in the UK.

Botox is most commonly used as an anti-wrinkle treatment, but has been trialled for numerous medical purposes in recent years.

Sports star Adrian Beltre is aiming to help young people avoid the need for emergency dentistry by promoting the benefits of good dental hygiene habits.

The Texas Rangers baseball player recently spent time with children in the Dallas area as part of a new oral health scheme created by Colgate and Walmart, ESPN reports.

Dominican Republic-born Beltre participated in a 'brush-a-thon' and spoke with youngsters about how regularly brushing teeth can prevent health problems emerging later in life.

"My parents were always getting on me to take good care of my teeth and gums," said the 32-year-old, who joined the Rangers in January this year after one season with the Boston Red Sox.

"We want kids to think brushing their teeth is fun," he added.

Colgate and Walmart's Building Smiles Together programme offers access to free dental screenings, treatment referrals and oral health education for children across the US.

Soap star Lucy Pargeter has spoken about her interest in cosmetic procedures, including Botox.

The Emmerdale actress, who plays Chas Dingle in the popular ITV1 show, told the Daily Mirror she has used the anti-wrinkle jab in the past and is planning another treatment soon.

"My Botox needs topping up. I can't at the moment because I'm doing non-stop emotional scenes, but I will have more," Pargeter explained.

She told the newspaper she has no problem with using liposuction, breast enlargement surgery and other procedures to make sure she always looks her best.

"I'll carry on getting things done for as long as I feel I need to," said the 33-year-old star, who joined the cast of Emmerdale in 2002.

Last month, Now Magazine reported that American singer Paul Abdul was having Botox injections and other treatments in preparation for her stint as a judge on the US X Factor.

The need for emergency dentistry could be reduced through the use of DNA analysis, scientists have claimed.

Breakthrough research from the University of Michigan's School of Dentistry will attempt to use DNA to predict whether or not patients are likely to suffer from gum disease in the future.

If positive results come out of the test, it could have important implications for preventative care against a wide range of tooth and mouth-related problems.

Dr Nigel Carter, chief executive of the British Dental Health Foundation, said the ability to diagnose gum disease early could vastly improve people's oral health.

"There is also a considerable long-term financial benefit to stamping out such a potentially harmful disease," he added.

"Cutting the risk of gum disease could save the government millions in costly treatments."

According to the NHS, between 50 and 90 per cent of adults in the UK are affected by some degree of gum disease. 

Emergency dentistry could be required for people who have spent time in hospital, new research has revealed.

According to the British Dental Health Foundation (BDHF), many hospitals are overlooking the wellbeing of the mouth and teeth, leading to potentially serious consequences for patients.

The study, which is due to be published in next month's Journal of Clinical Periodontology, examined hospital stays in the UK, US, France and the Netherlands between 1998 and 2009.

Plaque accumulation was one of the potential emergency dentistry issues that were found to increase during time in a medical facility.

Build-up of plaque can result in inflammation of the gums, which is not normally serious but can cause teeth to fall out in severe circumstances.

Dr Nigel Carter, chief executive of the BDHF, said: "It may be inevitable that oral care is seen as a low priority, but it is clear that more needs to be done to ensure that some of the risks are minimised."

Scientists in Europe have conducted research that could facilitate quicker healing processes for patients with dental implants in future.

A study from the University of Gothenburg and Astra Tech has led to the creation a new method of analysing the topography of titanium dental implants at a nanoscopic scale.

This allows researchers to analyse the way in which the implant is anchored to the bone, as well as giving insight into how this could be enhanced via changes to its smoothness, conductivity and natural oxide coating.

According to the report, this breakthrough could make it easier for new dental implants could be developed that are optimised for increased bone formation and better healing.

Johanna Loberg at the University of Gothenburg's department of chemistry said: "This would reduce the discomfort for patients and makes for a better quality of life during the healing process."

According to a recent Cape May County Herald report, dental implants are becoming more popular as a means of providing a natural-looking replacement for missing teeth.

Scientists from the University of Liverpool have won praise for a new clinical digital camera with the potential to revolutionise emergency dentistry in future.

The team of researchers has won a Medical Futures Award for its work on iDENTifi, a device that uses qualitative light-induced fluorescence technology to create images of the mouth with blue lights and special filters.

This technique can show up cavities, plaque and signs of tooth decay before they are visible to the human eye, with images that can easily be transferred to any standard electronic device for ease of assessment.

Eliminating the need for dyes or disclosing agents, iDENTifi could lead to the creation of new preventive dental strategies and could change the way dental care and dietary behaviour are managed.

Professor Sue Higham from the Department of Health Services Research and School of Dentistry said: "Winning this award will give us access to business expertise and networks which will help iDENTifi secure the recognition and investment needed to become a viable dental healthcare product."

Newcastle University was also presented with a Medical Futures Award for its work on syringe technology designed to remove the pain from emergency dentistry procedures.

Scientists at Newcastle University have won an innovation award for a new invention that could make emergency dentistry procedures less painful in future.

The team, led by dentist Dr John Meechan, was declared the winner in the dental and oral health section at the Medical Futures Innovation Awards for its pioneering acidity-neutralising syringe technology.

It utilises a special syringe cartridge to reduce the acidity of injections shortly before they are delivered, taking away a lot of the pain associated with dental procedures.

Dr Meechan expressed optimism over the future of the project, which remains in a "very early" stage of development.

However, he added: "This award could be a real boost in our aim of getting it on the market and used by dentists around the world."

Earlier this month, the Examiner reported findings from a Journal of Cosmetic Dermatology study showing that inhaling lavender could be a good way of reducing anxiety ahead of invasive procedures such as Botox injections.
