Wisdom Teeth Pictures Additions

So I added a few additional pictures to my wisdom teeth pictures section. These high quality photos of wisdom teeth are courtesy of Flickr users allowing me to use them on my site.

I particularly like the image I also added below for your viewing experience. This photo shows only one wisdom tooth but has a unique view in front of a dental mirror. It is also quite a bloody wisdom tooth.

After Removing Teeth Platelet-Rich Plasma May Aid In Faster Healing Times

A new study in the Journal of Oral Implantology shows platelet-rich plasma aid in speeding up healing and bone formation after removing a tooth.

If a tooth is extracted and the extraction site has poor recovery then excessive jaw bone loss  may delay the use of dental prosthetics or implants.

The study looked at patients who had their wisdom teeth removed.  One extraction site was treated with platelet-rich plasma where as the site on the other side of the mouth was served as control. The patients were examined for bleeding,  jaw bone density, healing ,pain, inflammation, and facial swelling for 24 weeks after the wisdom teeth removal occurred.

The researchers concluded the platelet-rich plasma treatment had a positive effect on bone density immediately following tooth extraction where as the control sites showed a decrease in bone density during the first week after the teeth were extracted.

The researches said it took roughly 6 weeks for the control sites to reach the same bone density as the platelet-rich plasma treated extraction site had reached by the first week.  Of note is that platelet-rich plasma did not have a substantial effect on pain, bleeding, and inflammation during the healing process.

Infections in the Mouth of Mother can Lead to Premature Birth

Researchers from Case Western Reserve University and their collaborators have determined bacteria in the mouths of pregnant women can contribute to pre-term birth (premature).

Around 12.7% of births in the U.S. are pre-term deliveries, which has increased by 36% increase over the last 25 years. Intrauterine infection is recognized as a main cause of pre-term birth as well as late miscarriage and still birth. The cause of intrauterine infections has long been attributed to bacteria ascending into the uterus from the lower genital tract. However the researchers have found that such infections are caused by bacteria in the mouth and in the vaginal tract.

Specifically, in the study saliva and plaque samples were injected into the tails of pregnant mice to determine what bacteria are capable of oral-uterus transmission. A diverse group of bacterial species were found to be in the mouse placenta, of which the majority originate in the oral cavity and are associated with adverse pregnancy outcomes in humans.

This suggests that a mother should make sure any bacterial infection in her mouth, such as the common one known as gingivitis, is under control while she is pregnant or planning to soon become pregnant.

Genes Linked to Cavities

Two recent papers y researchers at the University of Pittsburgh School of Dental Medicine and their collaborators suggest that specific genetic variations may be linked to higher rates of tooth decay (cavities) and aggressive periodontitis, which is inflammation and infection of the ligaments and bones that support the teeth.

Dental cavities have been found to be influenced by individual variations in a gene called beta defensin 1(DEFB1), which plays a key role in the first-line immune response against invading germs.

For one of the studies, the researchers analyzed nearly 300 anonymous dental records and accompanying saliva samples from the their dental registry, assigning each case a DMFT score based on the presence of decayed teeth, missing teeth due to caries, and tooth fillings. In addition each case also received a DMFS score, based on decayed teeth, missing teeth, and filled surface of a tooth.

Saliva samples contained one of three variants, dubbed G-20A, G-52A and C-44G, of the DEFB1 gene. Individuals who carried a G-20A copy had DMFT and DMFS scores that were five-times higher than for people who had other gene variants.

For the second study, saliva samples of 389 people in 55 families were examined to look for genetic links to aggressive periodontitis. They found hints of an association between the disease and the FAM5C gene. This particular gene has been previously found to play a role in inflammation in cardiovascular disease.

David After Dentist

I found a website http://davidafterdentist.com/ that is doing very well for pretty much just having a YouTube video and some background information.

The site features a video of a 7 year old who had a condition called hyperdontia and had to have a tooth removed. The video shows the aftermath of the kid in the backseat of his father’s car while his father takes a video with a flip video camera. His quite out of it from the anesthesia.

Apparently the video is generating the family six figures a year in income, which is very successful. This shows that one successful video can really take off and lead to fame as most of us know by now.
