Clinical Trial Summary
This study is designed to find out the effect of maintaining apical patency versus non
maintaining apical patency on post-operative pain after single visit endodontic treatment in
necrotic teeth with asymptomatic apical periodontitis
Description:
After taking approval from the ethical committee (AFID No 905/Trg-ABP1K2), this study is
planned at operative department in Armed Forces Institute of Dentistry, Rawalpindi from 01
June 2020 to 31 December 2020. Informed consent would be taken from 240 patients of 20-50
years of age from both gender with good general, mental and physical health who would be
selected for this study and would be randomly divided into two equal groups with the help of
scientific random number table.
The mandibular first molar teeth with asymptomatic apical periodontitis either with necrotic
pulps, without any intra-oral or extra-oral swelling or any draining sinus tract will be
selected for this study. Patients on preoperative analgesics and antibiotics, teeth with
calcified canals and open apex, previously traumatized teeth and root canal treated teeth
along with immune-compromised patients, pregnant and lactating mothers will be excluded from
this study.
The patients reporting to the Operative Dentistry Department of Armed Forces Institute of
Dentistry, Rawalpindi requiring root canals of their mandibular first molar will be screened
for inclusion by taking history, performing relevant clinical examination and necessary
investigations along with peri-apical radiographs. The whole procedure of the study will be
explained to the patients in Urdu. After taking written informed consent from the willing
participants of this study the procedure will be started. Two groups will be formed:
Group A: Patency group and Group B: Non-patency group Root canal treatment will be initiated
under local anesthesia and rubber dam isolation. Working length will be taken with apex
locator and will be confirmed with radiograph. The root canals will be instrumented with
ProTaper Next system under copious irrigation with 5.25% sodium hypochlorite (NaOCl) and 17%
EDTA solution.
In group A, a size 10 K file will be passed beyond the apical foramen between each instrument
change to maintain apical patency while in group B, K file will be carried up to the working
length only. A final peri-apical radiograph will be taken in the group A with the 10 K
patency file 01mm beyond the apical foramen to confirm patency.
To control the microbiological impact on post-operative pain 2.5% sodium hypochlorite and 17%
EDTA will be used as irrigants in both groups. Obturation will be done with cold lateral
condensation using Pro Taper Next GP points and permanent restoration will be done with
composite. At the end of this appointment patients will be given a visual analogue scale
(VAS), and will be advised to mark at the scale according to his pain intensity after 24
hours and 48 hours after the treatment and will be asked to bring these reading with him on
the next scheduled visit after one week for tooth preparation for metal ceramic crown.
Patients will be given analgesic and will be advised to take it only in case of severe pain.
VAS scores of less than 4 will be considered as no pain, score of 4-7 will be considered as
mild and/or moderate pain and scores of 8 and above will be considered as severe pain. (no
pain = <3, moderate pain = >4 to 7, severe pain = > 8). Frequencies, percentages, mean and
standard deviation will be calculated for qualitative variable like inter appointment pain
and for quantitative variables like gender; mean and standard deviation along with
percentages in each group will be calculated with SPSS 22. Chi-square test will be used to
compare the frequency of pain between the two groups after 24 and 48 hours of endodontic
treatment. The p value of <0.05 will be considered significant.
