Abstract

Foreign bodies in root canals are rarely seen, and usually the foreign bodies are accidently lodged and broken in root canals by the patients. Due to the difficulty of eradicating infection, foreign bodies may become sources of infection and hence they must be removed. This case report describes a clinical case in which a sewing needle was inserted into the root canal by the patient himself. Keywords: Foreign body, Sewing needle, Root canal, Template technique.

Abstract

The purpose of this study was to compare to evaluate the post operative pain with different calcium hydroxide formulations when used as intracanal medicament in root canal which was evaluated by VAS scale. Materials and Methods: The 150 subjects were randomly assigned to four groups and one control group depending upon the intracanal medicament: Group 1: Calcium hydroxide paste (Ivoclar) was used as intracanal medicament, Group 2: Calcium hydroxide paste with iodoform (Metapex) was used as intracanal medicament, Group 3: Calcium hydroxide points (Hygenic) was used as intracanal medicament, Group 4: Calcium hydroxide paste using chitosan (0.2%) as vehicle was used as intracanal medicament, Group 5: Control group containing dry sterile cotton. The incidence and intensity of preoperative pain and experienced post operative pain (on 6th, 12th, 24th hour and 48th hour) after first visit of treatment were assessed according to patient’s recordings in visual analogue scale. Results: The medicament causing least operative pain are ranked according to superiority as Calcium hydroxide paste > Calcium hydroxide points > Calcium hydroxide with chitosan > calcium hydroxide with iodoform Conclusion: At 6th postoperative hour, least post operative pain was recorded by the calcium hydroxide points and high post operative pain in calcium hydroxide with iodine (Metapex). At 12th, 24th, 48th postoperative hour least post operative pain was recorded by calcium hydroxide paste (Apexcal).  Keywords: Calcium hydroxide medicament, Calcium hydroxide points.
