I Love My Dentist Day

June 2nd 2018

Do your patients love you?

June 2nd is "I Love My Dentist Day", created in the US to show appreciation for dentists. A health day aimed at drawing attention to dental health. In industrialized countries, dental caries is one of the most frequent infectious diseases, with an incidence of roughly 95 percent1.

ZEISS has been contributing to technological progress for more than 170 years, with examination and surgical microscopes designed for use in dentistry, among other things. Find out more on this page.

General dentist Dr. Matthias Richter has a dental practice in Wernigerode (Germany) together with his wife Dr. Cornelia Richter. He uses the ZEISS dental microscope EXTARO 300.

Did you know that…

95%

… 95% of the population in industrialized countries get dental caries at least once in their lifetimes?1

1800 BC

… the first theory about the development of dental caries was developed around 1800 BC?2

30 Kg

… our teeth can withstand pressure of 30 kilos (66 pounds), and in extreme cases up to 80 kilos (176 pounds), so that we can chew practically any food?2

… the toothbrush as we know it with nylon bristles is celebrating its 80th anniversary this year?4

Microscopy is the key to more quality and reliability in dentistry

Almost every adult has had caries at some point in their lives. That is when the dentist comes into play, just like in the case of other dental diseases.

To enjoy the benefits of magnification and visualization, dentists use dental microscopes to diagnose and treat problems in the oral cavity for endodontics, restorative dentistry, implantology, and periodontics.

We at ZEISS want to give you an overview of the uses of microscopy in the field of dentistry. Spoiler alert! The combination of optical magnification and the fluorescence (see picture on the left side) mode in the EXTARO 300 dental microscope from ZEISS can help dentists preserve healthy tooth substance. This allows treatment of carious fillings efficiently, using a simplified procedure with considerable time savings.

Many doctors have already had very positive experiences with visualization and magnification in the field of dentistry including improvements to their own body posture. They want to share some of their experiences.

An Expert Shares his Experiences

A Hassle-Free Root Canal

A look behind the scenes at Dr. Richter’s practice in Wernigerode

Dentists can only fix what they can see,” says Dr. Matthias Richter: “Root canals are a prime example of what I mean. Caries could cause a tooth’s nerve to become infected, requiring treatment. If we can’t see the tiny channels inside a tooth, however, we won’t be able to do our job – at least not properly. 90 percent of upper molars have a small, fourth root canal that is easy to spot when magnified.

Dr. Matthias Richter

The patient leans back in the chair. It’s a sunny Friday morning at the dental practice of Dr. Matthias Richter and his wife Dr. Cornelia Richter in the old town of Wernigerode, central Germany. The treatment about to be performed lets anyone break out in a cold sweat.
The patient is having an old root canal filling removed from one of her molars. For Dr. Matthias Richter, who has been performing these procedures almost every day for seven years, this is nothing more than a routine procedure. Well actually, that’s not quite true.

In November 2017, Dr. Richter began working with a very important tool – a dental microscope. It is mounted on the ceiling of the treatment room and blends in well with the room’s bright, modern furnishings.
Dr. Richter sits up straight. He looks into his patient’s mouth through the eyepieces and silently works on the finest structures inside the tooth. The microscope provides excellent visualization, and supports the dentist with an ergonomic posture without having to lean forward; meaning, he can spend the next hour or so sitting comfortably.

After about 60 minutes of silence, he says: “We’re almost done here.” At the end, four thin, light-colored strands no longer than a cm are on the instrument table – these are the old cement fillings of the four root canals. The patient is treated with medication and a temporary filling, leaving the office with a smile on her face. On the next visit the canals will get a brand-new filling.

Further dentists share their experiences with visualization and magnification in dentistry:

Dr. Joachim Hoffmann (Germany) has been working with a surgical microscope in dentistry since 1999 and it has rendered him tremendous services.  

Assoc. Prof. Marko Jakovac (Croatia) shares his experiences with the “breakthrough visualization modes” in the dental microscope ZEISS EXTARO 300. Read his interview here.  


Digitalization in Dentistry

How an app facilitates easy patient communication and supports practical training

ZEISS is actively shaping digitalized medicine including dentistry. The ZEISS Connect App is a prime example of this. In combination with the ZEISS EXTARO 300 dental microscope it enables dentists to communicate interactively with their patients and supports the training of dental students. The user can show students and patients high-resolution images and videos of the relevant teeth.

The images shown are not only limited to those teeth requiring treatment; the app offers patients, students and dentists a comparison of the teeth’s condition before and after treatment. Also, the app enables dentists to inform patients in an easily understandable manner about their treatment plans and results. An integrated digital workflow supports automatic data transmission and clinical case documentation from the microscope.

The ZEISS Connect app demonstrates how ZEISS connects its products to customer workflows, offering added value.
 

Microscopy Training

Students learn the true value of magnification
School of Dental Medicine at the University of Pennsylvania

Penn is ranked 18th on the list of top dental universities around the world5 and is one of the well-renowned Ivy League6 universities in the USA.

ZEISS sustainably promotes microscopy in dentistry and has been working with the School of Dental Medicine at the University of Pennsylvania (Penn), USA for more than five years. Use of the microscope is a basic requirement for becoming a specialist in endodontics (root canal treatment). Examining samples under a microscope as part of the pre-clinical training of dental students is anchored in the Faculty's scientific curriculum, which is taught through practical seminars and a range of specialty courses. To foster this collaboration, ZEISS has provided the Faculty with three ZEISS EXTARO 300 dental microscopes for training in prosthetics.

In the pre-clinical training courses conservative dentistry is taught with the help of magnification. This underscores the trend towards comprehensive conservative dentistry, which includes clearly visualizing the transition from natural to artificial tooth material.

The Penn-ZEISS collaboration in figures:

  • About 250 dentists have already taken part in intensive courses on how to use microscopy techniques in dentistry.
  • Every year, eight specialists are trained as endodontists at Penn.
  • As part of international collaboration programs, approximately 7,200 people in ten countries across the world have attended week-long symposia receiving information about the great value of microscopy in endodontics.

Guideline for the prevention of dental caries

Dental caries can be prevented with consistent prophylactic measures. But what are these? Which measures are backed by scientific evidence? The first German guideline on "Prevention of Dental Caries in Permanent Teeth"1 provides some answers.

The guideline was created under the direction of the Deutsche Gesellschaft für Zahnerhaltung (German Association for Tooth Preservation) and the Deutsche Gesellschaft für Zahn-, Mund- und Kieferheilkunde (German Association for Dentistry and Oral and Maxillofacial Surgery). A total of 14 specialist associations contributed to this guideline.

After careful review and analysis of international research, the experts reached a consensus on seven core recommendations. Patients themselves should implement three of these every day, while four can be implemented in collaboration with their dentists.


 

Every day

In consultation with your dentist

  • Brush your teeth twice a day with a toothpaste containing fluoride

  • Follow a preventiveve dental hygiene regiment

  • Consume as little sugar as possible

  • Supplement your fluoride intake

  • Chew sugar-free gum after each meal to stimulate saliva production

  • If necessary: Chlorhexidine varnish with at least 1% CHX

 

  • Seal fissures at risk of caries
