Great job volunteers!!!
It is nice to see that kind of feedback.
I tell my staff that it will be hard work and the only pay they will get is in hugs, smiles and tears.
Can't tell you how often I have seen it.
From someone who just is grateful for being able to get something done, to the single mom who didn't know how she was going to afford to get her 17 year old daughter's wisdom teeth taken out.
If anyone wants to volunteer, I'm sure that they can still use runners and interpreters and such.
If anyone needs teeth taken out, I'll be there Friday and (hopefully) Saturday afternoon.

Fortunately the weather will be nice!
Even more importantly, the dentist will be able to identify gum disease and point the person toward treatment.
In my news feed I get every morning a report came up recently that there is a direct correlation between gum disease and alzheimer's. The researchers say they may even be able to reverse it possibly.
Here is a link to the report:

If you bled when you brushed your teeth this morning, you might want to get that seen to. We may finally have found the long-elusive cause of Alzheimer’s disease: Porphyromonas gingivalis, the key bacteria in chronic gum disease.
That’s bad, as gum disease affects around a third of all people. But the good news is that a drug that blocks the main toxins of P. gingivalis is entering major clinical trials this year, and research published today shows it might stop and even reverse Alzheimer’s. There could even be a vaccine.
Alzheimer’s is one of the biggest mysteries in medicine. As populations have aged, dementia has skyrocketed to become the fifth biggest cause of death worldwide. Alzheimer’s constitutes some 70 per cent of these cases and yet, we don’t know what causes it.
Bacteria in the brain
The disease often involves the accumulation of proteins called amyloid and tau in the brain, and the leading hypothesis has been that the disease arises from defective control of these two proteins.
But research in recent years has revealed that people can have amyloid plaques without having dementia. So many efforts to treat Alzheimer’s by moderating these proteins have failed that the hypothesis has been seriously questioned.

However evidence has been growing that the function of amyloid proteins may be as a defence against bacteria, leading to a spate of recent studies looking at bacteria in Alzheimer’s, particularly those that cause gum disease, which is known to be a major risk factor for the condition.
Bacteria involved in gum disease and other illnesses have been found after death in the brains of people who had Alzheimer’s, but until now, it hasn’t been clear whether these bacteria caused the disease or simply got in via brain damage caused by the condition.

Multiple research teams have been investigating P. gingivalis, and have so far found that it invades and inflames brain regions affected by Alzheimer’s; that gum infections can worsen symptoms in mice genetically engineered to have Alzheimer’s; and that it can cause Alzheimer’s-like brain inflammation, neural damage, and amyloid plaques in healthy mice.
“When science converges from multiple independent laboratories like this, it is very compelling,” says Casey Lynch of Cortexyme, a pharmaceutical firm in San Francisco, California.
In the new study, Cortexyme have now reported finding the toxic enzymes – called gingipains – that P. gingivalis uses to feed on human tissue in 96 per cent of the 54 Alzheimer’s brain samples they looked at, and found the bacteria themselves in all three Alzheimer’s brains whose DNA they examined.

“This is the first report showing P. gingivalis DNA in human brains, and the associated gingipains, co-lococalising with plaques,” says Sim Singhrao, of the University of Central Lancashire, UK. Her team previously found that P. gingivalis actively invades the brains of mice with gum infections. She adds that the new study is also the first to show that gingipains slice up tau protein in ways that could allow it to kill neurons, causing dementia.
The bacteria and its enzymes were found at higher levels in those who had experienced worse cognitive decline, and had more amyloid and tau accumulations. The team also found the bacteria in the spinal fluid of living people with Alzheimer’s, suggesting that this technique may provide a long-sought after method of diagnosing the disease.
When the team gave P. gingivalis gum disease to mice, it led to brain infection, amyloid production, tangles of tau protein, and neural damage in the regions and nerves normally affected by Alzheimer’s.
Cortexyme had previously developed molecules that block gingipains. Giving some of these to mice reduced their infections, halted amyloid production, lowered brain inflammation and even rescued damaged neurons.
The team found that an antibiotic that killed P. gingivalis did this too, but less effectively, and the bacteria rapidly developed resistance. They did not resist the gingipain blockers. “This provides hope of treating or preventing Alzheimer’s disease one day,” says Singhrao.
New treatment hope
Some brain samples from people without Alzheimer’s also had P. gingivalis and protein accumulations, but at lower levels. We already know that amyloid and tau can accumulate in the brain for 10 to 20 years before Alzheimer’s symptoms begin. This, say the researchers, shows P. gingivalis could be a cause of Alzheimer’s, but it is not a result.
Gum disease is far more common than Alzheimer’s. But “Alzheimer’s strikes people who accumulate gingipains and damage in the brain fast enough to develop symptoms during their lifetimes,” says Lynch. “We believe this is a universal hypothesis of pathogenesis.”
Cortexyme reported in October that the best of their gingipain blockers had passed initial safety tests in people, and entered the brain. It also seemed to improve participants with Alzheimer’s. Later this year the firm will launch a larger trial of the drug, looking for P. gingivalis in spinal fluid, and cognitive improvements, before and after.
They also plan to test it against gum disease itself. Efforts to fight that have led a team in Melbourne to develop a vaccine for P. gingivalis that started tests in 2018. A vaccine for gum disease would be welcome – but if it also stops Alzheimer’s the impact could be enormous.

Amazing, truly a noble cause and one that so many folks just do not seem to have the resources to receive. Good on all the Dental Professionals that give their time and skill to this cause. America is an amazing place!!

Interesting thing about the link between Periodontal bacteria and Alzheimer’s is that there have been other direct links between periodontal disease and bacteria and Heart Disease and ED.
Pays to keep em clean.

I have to take pre-meds before any dental procedure. Initially, it was because I had mitral valve prolapse. Then, after busting up my hip and having it repaired, I was told I no longer needed it for the MVP, but because of all the hardware in my hip. Don't know all the ins and outs, but the dentist says take 'em, so I take 'em. Remember Brad Edwards ... In Your Corner on channel 4 years ago? I was told his situation was similar to mine with the MVP. He died as the result of an infection that set up after a dental procedure. Yeah ... take care of 'em and keep 'em clean!
Very nice thing for all the dental volunteers to do !!!!
Just a reminder to all that this is going on tomorrow and Saturday.
I'm Packed and ready to go. Load up the team tomorrow and drive up to the Fairgrounds.

Good luck, and I hope it all goes well and your team finds it immensely rewarding!
