Clinically,What is the difference between CHRONIC & ACUTE periradicular periodontitis

[Dr.Dohaithem]

Chronic : No symptoms
Acute : Produces pain on biting and percussion

Thank you for these information

what about Palpation in acute periradicular periodontitis ?? do you think the patient will feel pain or not ??

I think yes in one situation ( where the PDL is in direct contact with the mucoperiosteum):rolleyes:

Did you know that the word "periradicular" was advocated by the AAE when Professor Torabinejad was the president...and then the glossary of the AAE showed the change from Periapical to Periradicular (I have the original if you wish to see it). Then, now other group came and reverted back to Periapical !!! Claiming that the former means all the area around the root, While the latter only the apical area....I thought that was common sense from the beginning is not??

AS fare as Acute Vs. Chronic issue...the word Acute= pain....wither spontaneous continuous pain, feeling of pressure..ect. While Chronic is silent. if the cortical plate has been invaded during the course of the disease, it will feel different or painful on palpation wither it is chronic or acute

[al-nasser]

I totally agree with you about the Periradicular
as far as I know preiradicular means exactly :- apical + lateral + furcal
while periapical means :- around the apex

AS fare as Acute Vs. Chronic issue...the word Acute= pain....wither spontaneous continuous pain, feeling of pressure..ect. While Chronic is silent. if the cortical plate has been invaded during the course of the disease, it will feel different or painful on palpation wither it is chronic or acute

you are absolutly right dr.khaled
although acute & chronic is histological term
it seems that many papers confined these terms tward symptomatic and asymptomatic
for example:- the abcess it self is an acute process however, you will find many paper stated that
"once the abscess drain it will become chronic "
to rephrase this statement it means " once the abscess drain the patient will be asymptomatic "

the question here is :- what is the difference between acute and chronic in the mean of immunological as well as in microbial aspect :D

[Khaled Balto]

I thank you a milliong Dr. Abdulrahman for you great explanation...wow ..you have such an amazing critical thinking.....I did buy you explanation re-Symptomatic Vs. Asymptomatic In comparison to Acute Vs. Chronic.

According to the majority of reports, Symptomatic= More microbial load......without specification of any particular bacteria.....

The immunologic knowledge is basic to us all is not?

[diagnoza]

Acute periodontitis: sponatanouse pain and continouse,pain to percusion ,fast proces etc
There are 2 types of acute periodontitis=serouse and purulent.The purulent fase is more painfull and has 4 stages (periodontal,bone,subperiostal and submucosal)

Chronic periodontitis:NO PAIN(pain just in riacutising process)


Histopathology:
In acute periodontitis is evidente====> ATLERATION & EXUDATE
In chronic Periodontitis is evident====>ALTERATION &PROLIFERATION

Radiographic examination: ACUTE don't look on Radiography
CHRONIC=YES
