The parodontium & probing - Introduction
6 important questions on The parodontium & probing - Introduction
Why do we use a probe (12p)
- Essential component of assessment and diagnosis of the patient's periodontal duisease status
- Asses the periodontal status before creating a care plan
- Measure pocket depth and clinical attachment level (CAL)
- Mucogingival examination (ripe/wrinkleTest)
- Bleeding on probing (BOP)
- Furcation involvement
- Measure gingival recession
- Gingival tissue consistency
- Lesion measurement
- Evaluate succes of treatment
- Evaluation at continuing care and periodontal maintenance appointments
What are the characteristics of the probe?
- Smooth, rounded tip designed for examining the depth and topography of a gingival sulcus or periodontal pocket
- It has tree parts: the handle, angled shank, and working end
with is the probe itself. Angle between shaft and working end 90° or more
- It is made of either stainless steel or plastic for screenings and titanium for implant probing
- Calibrated in millimeters at intervals specific for each kind of probe; some have color coding
- Curved working end: paired furcation probes have a smooth, rounded end for investigating the topography and anatomy around roots in a furcation. Example nabers probe
Where do we probe?
What are the classification of the probe?
The pocket (or sulcus) is continuous around the tooth and the entire sulcus needs to be measured
- 1st generation: traditional or manuel probes
- 2st generation: probes with controlled force application
- 3th generation: automated probes
- 4th generation: recording sequential probe positions along gingival sulcus
- 5th generation: ultrasonographic periodontal probe
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
Explain the angulation of periodontal probing
- Proximal surface are approached by entering from both the facial and lingual aspects of a tooth
- Gingival and periodontal infections begin in the col area more frequently than on other areas
- Pocket depth may be deepest directly under the contact area because of crater formation in the alveolar bone
- CAUTION!!! Do not over angulate
What is the probing accuracy with a normal healthy tissue?
What is the probing accuracy with gingivitis and early periodontitis?
What is the probing accuracy with advanced periodontist?
The probe tip is within the junctional epithelium
The probe tip passes through the junctional epithelium to reach attached connective tissue fibers
Explain how we record periodontal pocket depth?
- The pocket/sulcus is measured completely around each tooth
- Record the deepest measurements for each of the six areas around the tooth
- Areas 1, 3, 3 and 6 extend from the line angle to under the contact area
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
