Abstract

Introduction: Application of intracanal medicament in infected root canals inbetween
endodontic visits is targeted for additive disinfection as well as post-operative
pain prevention. Aim: to elucidate the palliative effect of calcium hydroxide through
comparative study of the post-endodontic pain in patients with necrotic pulp associated
with symptomatic apical periodontitis using a modified visual analogue scale (MVAS).
Materials and methods: Sixty patients with single-rooted lower premolars diagnosed
with pulp necrosis with symptomatic apical periodontitis were included in the study.
The participants were divided into three groups; Two experimental and one control
(n=20 per group): G I (control group) root canals did not receive any intra canal
medication, GII: root canals received calcium hydroxide intracanal medication without
iodoform, and root canals in G III received calcium hydroxide intracanal medication
with iodoform. All three groups received glass ionomer coronal temporization by glass
ionomer. The patients recorded their pain scores in (MVAS) pre-operatively ,4, 6, 12, 24,
48, 72 hrs and after one week. Results: At all-time intervals, no significant change was
detected in the pain scores in-between the experimental and control groups ( P<0.05).
Conclusion: Calcium hydroxide with /without iodoform has neutral effect on postoperative
pain.
