The effect of variation in inter-appointment time on the incidence of post-operative pain in single-visit versus two visit endodontics: An in vivo study

Abstract

Aim:This clinical study was conducted to observe and note the effect of variation in inter-appointment time period on the incidence of post-operative pain following single-visit versus two visit endodontics in vital and nonvital teeth with and without periapical radiolucency. Materials and Methods: A total of 80 adult patients requiring root canal therapy in anterior and premolar teeth were selected for this study and divided into four groups. Two sitting root canal treatment was carried out in three groups (Group 1 with inter-appointment time of 72 h, Group 2 with inter-appointment time of 48 h and Group 3 with inter-appointment time of 24 h) and single sitting root canal treatment was carried out in one group (Group 4). The subjects were recalled after 2 weeks and instructed to fi ll out a series of self-report questionnaires for responses about pain in the interim after 1 day, 2 day, 3 day, 1 week and 2 weeks. Results: Though comparison of pain incidence in different groups was not statistically signifi cant, there was a greater tendency for post obturation pain incidence in teeth treated with single sitting root canal therapy and those with inter appointment period of 72 h. Results obtained were comparable to those obtained by several investigators.

Preliminary in vivo Investigation into the Relationship between Canal Preparation Protocol and Incidence of Postoperative Pain in Single-visit and Two-visit Endodontic Therapy: A Randomized Controlled Clinical Trial

“…However, a second major finding of the study is that when present, postoperative pain after a rotary canal preparation is expected to last longer, which supports our findings quite precisely. Several researchers have worked on various variables like irrigation techniques, 12 obturating techniques, 13 variation in intraappointment time period, 3 and administration of different analgesics as pretreatment medication 14 in an attempt to device the best treatment protocol that results in minimum postoperative endodontic pain.…”

“…But even with the use of rotary methods, postoperative pain continues to appear with high frequency. 1,2 Much research has gone into the alteration of variables like interappointment time span 3 and number of sittings to reduce postoperative pain. Till date, there is very little research that compares post operative pain following hand vs rotary canal preparation techniques.…”
