The University of Pittsburgh discovered that people who gulp down any amount of alcohol are more at risk of their fillings coming out within two years then teetotal folk, no matter what material the implants are made out of. Men who drank and smoked had the highest rate of fillings coming out.
To reach their conclusions, experts from America and Brazil looked into dental records containing information about patient filings and failure rates of up to five years after the procedure from a dental school in Pittsburgh.
It was found that the failure rates of the fillings weren’t that different between composite (tooth-coloured) or amalgam (metal) fillings, the latter of which is known to contain more toxic ingredients.
Patients’ lifestyles were also analysed, with factors such as smoking and drinking habits taken into account as well as DNA samples, allowing the researchers to identify any genetic factors that could affect the fillings. This showed that a gene which contained the enzyme matrix metalloproteinase (MMP2), found in teeth, increases the likelihood of filling failure as MMP2 may affect the bond between the tooth surface and implant.
Furthermore, alcohol was also identified as a factor that can damage the strength of fillings, as was smoking.
“A better understanding of individual susceptibility to dental disease and variation in treatment outcomes will allow the dental field to move forward,” researcher Alexandre Vieira, of the University of Pittsburgh, said of the results, published in the journal Frontiers in Medicine.
“In the future, genetic information may be used to personalise dental treatments and enhance treatment outcomes.”© Cover Media
