  • 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)

Brazil’s lower chamber handed right-wing President Jair Bolsonaro his first defeat in Congress on Tuesday, the day before his government presents its most important legislative proposal to rein in a gaping budget deficit and spur growth.

The house voted overwhelmingly to suspend an executive order by the Bolsonaro government that altered Brazil’s freedom of information law to broaden the number of officials allowed to designate data and documents as secret or ultra-secret.

Lawmakers voted 367 to 57 to fast-track a bill overturning the secrecy measure and government whips were unable to muster votes to avoid defeat.

The bill must still be voted on by the Senate, but the reversal showed that Bolsonaro, who took office on Jan. 1, has not yet been able to organize a coalition in Congress to back his legislative agenda.

On Wednesday, Bolsonaro will send to Congress his plan to overhaul Brazil’s generous and costly pension system that eats up more than half of federal spending and is the main factor behind an unsustainable budget deficit.

Approval of pension reform is vital for the recovery of investor confidence in Latin America’s largest economy.

The defeat on the floor of the house came one day after Bolsonaro fired a senior minister amid a scandal involving campaign financing for some of his party’s congressional candidates in the October elections.

The ousted minister, Gustavo Bebianno, was instrumental in getting Bolsonaro elected but had a run-in with one of the president’s sons, triggering the weeks-old government’s first cabinet crisis.

In a note to clients, analysts at Eurasia Group said the scandal indicated the administration’s political team was in disarray, but they still expected the pension reform to get passed, albeit in a less ambitious version. (VOA)
