Scientists discover drug to re-grow tooth, seal cavities

A recent scientific discovery has shown that Tideglusib, a drug developed for and trialled to treat Alzheimer’s disease happens to promote the natural tooth re-growth mechanism, allowing the tooth to repair cavities.

This breakthrough suggests that dental fillings may soon be left in the ash heap of history.

The discovery was captured in a press release copied the Ghana News Agency.

Tideglusib works by stimulating stem cells in the pulp of teeth, the source of new dentine.

Dentine is the mineralized substance beneath tooth enamel that gets eaten away by tooth decay.

Teeth can naturally regenerate dentine without assistance, but only under certain circumstances.

The pulp must be exposed through infection (such as decay) or trauma to prompt the manufacture of dentine.

But even then, the tooth can only re-grow a very thin layer naturally-not enough to repair cavities caused by decay, which are generally deep.

Tideglusib according to the release changes this outcome because it turns off the GSK-3 enzyme, which stops dentine from forming.

In the research, the team inserted small, biodegradable sponges made of collagen soaked in Tideglusib into cavities.

The sponges triggered dentine growth and within six weeks, the damage was repaired.

The collagen structure of the sponges melted away, leaving only the intact tooth.

The release further noted that the procedure has only been used in mouse teeth.

King’s College London Dental Institute Professor and lead author Paul Sharpe had said “Using a drug that has already been tested in clinical trials for Alzheimer’s disease provides a real opportunity to get this dental treatment quickly into clinics.”

He added that, “The simplicity of our approach makes it ideal as a clinical dental product for the natural treatment of large cavities, by providing both pulp protection and restoring dentine.”

The team suggested more work needed to be done on the finding.

Most Ghanaians have been initiated into occultism by their Pastors – Papa Shee

Evangelist Papa Shee says most Ghanaians have been initiated into occultism by Pastors. According to him, most Pastors in Ghana currently are occults and with the way they are been celebrated by their followers, they initiate them into occult groups without their knowledge. He mentioned that Ghanaians lack knowledge and that has always been the reason why Pastors take advantage of them. Related Posts Quoting a Scripture from Matthew, Papa Shee mentioned that no one should refer to a man as his/her spiritual father because the word speaks against it. He indicated that he has come back to Ghana to open the eyes of ignorant Ghanaians so that they see the light.

Residents of Samreboi cry on gov’t to fix their roads

Residents of Samreboi are up in arms with the Government of Ghana over neglect of their roads. According to residents, It has become very worrying as their bad road network is affecting not only economic activities but also their social activities. Residents of the timber and Cocoa producing town in the Western Region of Ghana say they have been unfairly treated by several governments; the neglect they say they do not know what to attribute it to. A worrying feature of their roads they say is the fact that moving from Samreboi to neighbouring villages and towns become impossible especially during the rainy season hence bringing economic activities to a standstill. Residents say even though the year has been declared “Year of Roads” they are yet to see a kilometre of road being constructed. To the Youth especially, leaders in their part of the country have failed them after years of exploiting them for their own interest. They say they will advise themselves if nothing is done ab...

Chile, the last few weeks have been filled with the ongoing relationship drama involving “Love & Hip Hop Hollywood” stars Ray J and his wife Princess Love. Everyday there seems to be a new development—but this latest one could mean that all the messiness is over. #Roommates, by now you already know that during the recent Soul Train Awards where Ray J was a co-host on the red carpet, his wife Princess Love accused him of leaving her and their daughter Melody stranded with no way home. That accusation was followed with Princess being blocked on Instagram, her airing out his alleged hangouts with strippers and stating that she was going to file papers to officially go through with a divorce. Earlier this week, things seemed to have settled a little when Ray J was finally reunited with his daughter after not seeing her for a bit. He posted a video of little Melody asleep on his chest and referred to her as his “heart.” Well, the latest social media activity by Ray J appears to me...
