New Nanotechnology may Hold Key for Developing Longer-Lasting Implants By: Tanya Varimezova

TiO2 nanotubes etched in titamium.

Recent research from the Michigan Technological University has shown significant strides in developing a better, long-lasting, and transparent implant through the use of nanotechnology. The hopes for the new implant are that it will alleviate the problem with bacterial infections at implant sites, and separation of the implant from the bone. A dental implant is a titanium post placed into the jawbone, and covered by an artificial tooth. Some implants fail to heal properly, and therefore easily fall out. This can be caused by bacterial infections that develop around the implant, causing the bone to become even more fragile and unable to grow

properly around the implant. Thus, reconstructing an implant that has fallen out, which initially costs between $2,000-$4,000, becomes even more difficult and expensive. Tolou Shokuhfar, assistant professor of mechanical engineering at MTU has been collaborating with Cortino Sukotjo, clinical assistant professor at the University of Illinois at Chicago College of Dentistry, to develop a dental implant whose surface is made of TiO2 nanotubes. Experimental data has shown that bone is able to grow better on this type of surface, rather than the traditional titanium surface. This bodes well for longer-lasting dental implants. Furthermore, Shokuhfar, in collaboration with Alexander Yarin, professor in UIC’s Department of Mechanical and Industrial Engineering, have shown

Fall New Members’ Retreat By: Tiffany Ju

The Pre-Dent Press that this type of surface coating, if infused with sodium naproxen, an anti-inflammatory drug, can better diffuse the drug once the implant is successfully placed in the jawbone. This finding suggests that the post-operative side effects of treatment can be curbed to an extent, since sodium naproxen can be delivered in proper doses to the right places at the right time. A third advantage of this new implant technology is that it can help prevent post-operative bacterial infections. The TiO2 nanotubes can be loaded with silver nanoparticles. Silver has been shown to kill bacteria, thus possibly preventing biofilms from developing at implant sites. Shokuhfar has been working with Craig Friedrich, Richard and Bonnie Robbins Chair of Sustainable Design and Manufacturing at Michigan Tech, on unpublished research regarding orthopedic

On September 28, 2013, we had our New Member’s Retreat. The day started off with members getting assigned to families so we could engage in some friendly competition. Our first ice-breaker was a Charades-Pictionary hybrid to show off our acting and artistic skills. Next, we all embarked on an elaborate picture and video scavenger hunt to develop our bold and competitive sides. Activities ranged from tame ones, such as taking a picture with a bear statue and rolling down 4.0 hill, to difficult tasks such as hugging a random stranger and taking over a tour group. Afterwards, we were all treated to delicious pizza, fruit salad, and vegetable platters. The fun continued with a zombie apocalypse simulation, where we answered questions that corresponded with our personalities and what role we would play in the dental community. Each personality group teamed up to build a dental office out of random materials such as graham crackers, paper clips, and Styrofoam. Every dental office was unique and demonstrated fantastic teamwork. The retreat was successful in letting all the members get to know each other better and showing

The fourth benefit of the implant is of cosmetic nature. Due to the TiO2 nanotube transparency, the implant can be better disguised for a more natural look. Shokuhfar states that the integration process of this new implant into the clinical setting would be smooth, since the change is small but significant. The procedure would be the same, but the vast benefits of TiO2 nanotube coating would drastically help the success rate of dental implants. Sources: Image source: html Goodrich, Marcia. “Smile!

Halloween Candy and Teeth By: Tiffany Ju

Halloween is a wonderful day full of costumes and spooky decorations…and mounds and mounds of candy. It’s not a secret that candy causes cavities, but how exactly does it happen? Most candy contains sugar, which is a carbohydrate. Cavities are caused by bacteria in your mouth that feed on carbohydrates and produce acid. The acid breaks down tooth enamel and let the bacteria live in a hole in your tooth—a cavity. Once cavities get beyond your enamel and into the soft dentin layer, they get bigger

very quickly and can eventually get into the nerve, leading to a root canal-ouch! An important fact is that the amount of carbohydrates you eat does not matter as much as how long your teeth are exposed to it. This means that eating a lot of candy at once and brushing immediately after is better for your teeth than portioning it out during the day (although not better for your overall health.)

your teeth and saliva cannot wash them away. •Sour candies-these are very acidic and break down tooth enamel. •Sugary snacks (candy corn, cookies)-sugar causes tooth decay. Best candy for your teeth: •Sugar-free lollipops and hard candy-these stimulate saliva, which helps prevent cavities. •Sugar-free gum-removes food particles and stimulates saliva production. Some dentists are even offering to buy kids’ Halloween candy for $1 per pound and donating them to troops overseas along with toothbrushes and mouthwash! Have a

The good news is not all candy is equal, so by choosing certain candies you may be able to avoid any cavities. No matter what you choose to eat, it is good for your teeth to brush and floss every day, Happy Halloween, everyone! preferably soon after eating. Some of the worst candies for your teeth include: •Chewy/sticky treats (gummy candy, taffy)-these get stuck in

Just about an hour commute away from Berkeley, right near Golden gate park in the beautiful city of San Francisco, you will see UCSF School of Dentistry. The School of Dentistry operates 14 clinics at three sites, and provides more than 120,000 patient visits per year. The school itself is highly reputable and is one of the highest ranked dental school amongst the nation. The School of Dentistry offers multiple programs such as DDS program, DDS/PhD program, DDS/MBA program, MS in dental hygiene and graduate programs. General practice resident programs and advance general dentistry programs are also available. Other than DDS and PhD programs, UCSF offers a wide range in field specializing such as: dental public health Endodontics geriatric dentistry orthodontics pediatric dentistry periodontology prosthodontics oral and maxillofacial surgery oral medicine

The curriculum is very simple and traditional. In your first 2 years as a dental student, you will be taking the required basic graduate level sciences, such as physiology, anatomy, biochemistry, histology, and pre-clinical education. By the third and fourth year, dental students start their clinical education. The school works at a pass/no pass system and there are no class rankings. This causes your application for specialty Overall GPA- 3.54 programs to rely heavily on letters of recommendation and board scores. Science GPA- 3.49 UCSF is known by many dental students for their strong clinical exposure. The school is heavy on didactics and heavy work on hand skills. Additionally, the school is very research extensive. The School of Dentistry in 2007 and 2011 ranked first among all dental schools in NIH research funding. As a research powerhouse, this provides pathways for dental students to work close with many other dental students, researchers, and professors, providing an easier approach to form relationships amongst colleagues and faculties, a good stepping stone to specializing.  UCSF is a very prestigious school that offers students not just their degrees, but rather a rejuvenating four year experience and an intuitive way of thinking about dentistry.

We hope to provide you with all you need for your future endeavors and that you find your time with the club as worthwhile as we have found ours. GO BEARS! Your President, Michelle Khouri

or taking a break from the intensity of the Berkeley classes, these are all By: Nerissa Ignacio very common and reasonable reasons for students to take that yearoff. In fact, did you know that the average age of incoming admitted dental students is 23-24 years old? The idea of a gap year is growing to be quite common for pre-dental students and is progressing to be a social norm. Keep in mind that a gap year does work with or against you. To help your gap year work with you, here is an assembled list ou may hear students say this a of tips for a gap year done right: lot. “Oh.

Dental schools would love to see what you did in that oneyear gap, and the question about the gap year are usually brought up during interviews. Remember to state your purpose for the gap year and say what you plan on doing.

Technological Advances in Dentistry by: Amanda Israel


he practice of dentistry has undergone tremendous change over the past decade as advances in technology have become commercially available to the public. Small intra-oral video cameras, CAD/CAM applications, digital X rays, and 3D imaging as well as printing, are now available for daily use in all specialties of dentistry. Intra oral cameras consist of a wand with a built in camera that can take detailed color pictures of a patient’s teeth and their tissues. These pictures are then displayed on a screen, and can be printed by a thermal printer. The images taken from an intra oral camera can be utilized to show a patient if they have cracked fillings, broken teeth, or areas in their mouth that may require attention from an oral surgeon.

What has PDS been up to? K to College

By: Amanda Israel On September 28, 2013 Pre-Dental Society members volunteered at the K to College community service event that was held at UC Berkeley’s International House. K to College is a nonprofit organization that was started by UC Berkeley students and it’s purpose is to provide school supply and dental kit initiatives to disadvantaged students all throughout California. Since it has started, it has helped over 220,000 school children within 60 school districts in California. The event was very well organized and it consisted of packaging school and dental hygiene supplies into tote bags which were later sent out that day to be donated to the children. It was a very enjoyable experience and it felt great to be able to give back to the kids in our community.
