Washington: Fillings may not be the best way to tackle tooth decay in children, suggests a recent study. Findings from a major dental trial suggest that preventing tooth decay from occurring in the first place is the most effective way for parents to help avoid pain and infection from decay in their children's teeth.
A three-year study comparing three different treatment options for tooth decay in children's teeth, led by dentists from the Universities of Dundee, Newcastle, Sheffield, Cardiff, Queen Mary University of London and Leeds, has found no evidence to suggest that conventional fillings are more effective than sealing decay into teeth, or using prevention techniques alone, in stopping pain and infection from tooth decay in primary teeth.
The Fiction trial, the largest of its kind to date, also found that 450 children who took part in the study experienced tooth decay and pain, regardless of which kind of dental treatment they received. "Our study shows that each way of treating decay worked to a similar level but that children who get tooth decay at a young age have a high chance of experiencing toothache and abscesses regardless of the way the dentist manages the decay," said Professor Nicola Innes, Chair of Paediatric Dentistry at the University of Dundee and lead author .
"What is absolutely clear from our trial is that the best way to manage tooth decay is not by drilling it out or sealing it in -- it's by preventing it in the first place," continued Innes in the paper published in the Journal of -- Dental Research. During the study, more than 1,140 children between the ages of three and seven with visible tooth decay were recruited by dentists working in one of 72 dental clinics throughout the country.
One of the three treatment approaches was then chosen randomly for each child's dental care for the duration of the trial, which was up to three years. The first approach avoided placing any fillings and aimed to prevent new decay by reducing sugar intake, ensuring twice-daily brushing with fluoridated toothpaste, application of fluoride varnish and placing of fissure sealants on the first permanent molar (back) teeth.
The second option involved drilling out tooth decay, which was based upon what has been considered the standard "drill and fill" practice for more than 50 years together with preventive treatments. The third treatment strategy was a minimally invasive approach where tooth decay was sealed in under a metal crown or a filling to stop it progressing together with preventive treatments.
The main trial findings found no evidence to suggest that any of the treatment strategies were better than another in terms of making a difference in children's experience of pain or infection, quality of life or dental anxiety between groups. All three different ways of treating decay were acceptable to children, parents and dental professionals.
