College of Dentistry and Dental Clinics

Dean's Message

As a proud alumnus myself, I know that our alumni are a vital part of the college's efforts to improve oral health care in Iowa. For most Iowans, you are the face of our college and of the dental profession in Iowa. I've had the privilege of meeting with many esteemed alumni at various dental meetings this past weekend, and I am looking forward to reconnecting with more of our alumni at the Iowa Dental Association reception next Friday at the Iowa Dental Association's Annual Session in Des Moines. ~Clark Stanford

Beth Knudsen: Wellness Hero

"Beth rides her bike to work when the weather allows; what a woman! She follows this up by doing yoga over her lunch hour and inviting others to participate. Beth is a cheerleader, for health and hospitality! Her inclusion and invitation to others, combined with her kindness, her even keeled attitude, and down-to-earth business and educational rationale makes her my Wellness Hero.

April showers bring May flowers

With signs of Spring piling up—pelicans migrating through, a bunny visiting Spring-starved dentists, and all those April showers—it won't be long until we get some May flowers.

A figure from the paper 'Pooling Individual samples' showing the power of different pools of samples

Collaborative and Innovative Research

CL Comnick, C Vidal, XJ Xie, Pooling individual samples: Effect on study power, JADA Foundational Science, v 1, 2022.

For biological studies, which are often used in dental and oral health research, researchers often need to group together multiple independent samples to have sufficient physical material for testing. For example, Cristina Vidal was extracting protein from dentin powder. However, a single tooth did not provide enough of the dentin powder for independent samples. This paper outlined the best practice in these circumstances. That is, it is statistically ideal to treat all specimens as independent if possible, but if pooling is unavoidable, as it was in Vidal's project, the authors showed that it is preferable to use independent samples and combine them into the smallest clusters possible. In such cases, the study power was still acceptable (>80%). Therefore, when necessary, pooling can be used to perform experiments without a significant loss of power.

Iowa Trailblazers: Radiology from 1917-1950s

In 1917, a new building was constructed for the College of Dentistry on the corner of Capitol and Market St. The building had more space for patient care, and designated spaces for oral surgery, research, demonstration, and dental care for children. It also had a dedicated X-ray room “supplied with the best apparatus procurable for roentgenology [another name for radiology]…”. The photo shows the X-ray room circa 1950s.
