  • Indulging in smoking or drinking alcohol may not only damage your teeth but also lead to increased incidences of failure in dental fillings, warned researchers.

The findings, led by researchers from the University of Pittsburgh, showed that within two years of the dental procedure, Dental fillings failed more often in patients who drank alcohol, while the overall filling failure rate was higher in men who smoked.

Furthermore, people with a difference in the gene for matrix metalloproteinase (MMP2) — an enzyme found in teeth — were at increased risk of Dental filling failure.

This could be because MMP2 might be able to degrade the bond between the filling and the tooth surface, potentially leading to failure, the researchers said.

The results, published in the journal Frontiers in Medicine, suggest that genetic analysis might help dentists to personalize treatments for their patients, which could lead to improved outcomes.

“A better understanding of individual susceptibility to dental disease and variation in treatment outcomes will allow the dental field to move forward,” said Alexandre Vieira, a researcher from the varsity.

“In the future, genetic information may be used to personalize dental treatments and enhance treatment outcomes,” Vieira added.

For the study, the team from America and Brazil analyzed dental records of 807 patients.
Fillings can fail for a variety of reasons, including re-emergence of the initial tooth decay or the filling becoming detached.

The researchers also examined if newer composite resin Dental fillings are as durable as traditional amalgam fillings, which have been in use for more than 150 years but which contain mercury, a toxic metal.

The researchers found that overall, there were no major differences between patients receiving amalgam or composite Dental fillings in terms of filling failure rates. (IANS)

Cannabis Use Has Lasting Effects on Cognitive Skills in Teenagers Than Alcohol

Moreover, these increased with cannabis use and also were long-lasting compared to alcohol

While both alcohol and marijuana misuse are known to be associated with impairments in learning, memory, attention and decision-making, as well as with lower academic performance, a new study claimed that cannabis use has lasting effects on cognitive skills in teenagers than alcohol.

The findings, led by researchers at Universite de Montreal, showed cannabis affected cognitive functions such as perceptual reasoning, memory recall, working memory and inhibitory control.

Moreover, these increased with cannabis use and also were long-lasting compared to alcohol.

“Increases in cannabis use, but not alcohol consumption, showed additional concurrent and lagged effects on cognitive functions such as perceptual reasoning, memory recall, working memory and inhibitory control,” said Patricia Conrod, from the varsity.

“Of particular concern was the finding that cannabis use was associated with lasting effects on a measure of inhibitory control, which is a risk factor for other addictive behaviours, and might explain why early onset cannabis use is a risk factor for other addictions,” added Jean-Francois G. Morin, doctoral student at Montreal.

“Some of these effects are even more pronounced when consumption begins earlier in adolescence,” Morin added.

For the study, published in the American Journal of Psychiatry, the team followed a sample of 3,826 Canadian high school students from 7th to 10th grade over a period of four years.

In a context where policies and attitudes regarding substance use are being reconsidered, this research highlights the importance of protecting youth from the adverse effects of consumption through greater investment in drug-prevention programmes.

“While this study did not detect effects of teenage alcohol consumption on cognitive development, the neurotoxic effects may be observable in specific subgroups differentiated based on the level of consumption, gender or age,” Morin said. (IANS)
