Evaluation of postoperative pain after 1 and 2 visit root canal treatment in mandibular and maxillary teeth

Evaluation Of Postoperative Pain After 1 And 2 Visit Root Canal Treatment In Mandibular And Maxillary Teeth The aim of the present study was to investigate postoperative pain and flare-ups during and after endodontic treatment of preoperatively painful, symptomatic, multi-rooted with vital teeth and factors related to treatment. These factors are the number of treatment appointments/ used medicaments type and different instrumentation systems. In this prospective randomized clinical study, ninety patients aged 14-60 years requiring RCT on symptomatic, painful, vital, multi-rooted teeth teeth with vital pulps preoperatively were included. The teeth were randomly assigned to two groups (n = 45) according to the instrumentation system used: ProTaper Universal(Tulsa Dentsply, Tulsa, OK, USA) continuous rotary system or Reciproc(VDW, Münih, Germany) reciprocating systems. Then in each group its own assigned to three sub-groups (n =30) according to the number of treatment appointments/ medicaments type used: one visit, calcium hydroxide medicated two visit and chlorhexidine medicated two visit. Root canal treatment were performed by one endodontist with a standard treatment protocol. Postoperative pain at 12, 24, 48 hours after root canal preparation and postobturation pain at beginning, 12, 48 hours after root canal filling was evaluated with Vision Analog Scale (VAS). In our study the variables of treatment; root canal instrumentation systems and the number of treatment appointments/ used medicaments had no effect on postoperative pain severity and incidence and there was no statistically significant difference ( p > 0.05). None of the 90 participants reported flare-ups during the period of the study. Tooth type and gender were determined to have no effect on postoperative pain and there was no statistically significant difference (p > 0.05). Postoperative pain at 48 hours was found to be high in the maxillary tooth than mandibular tooth (p=0,031). At 24 hours postoperative pain severity was higher in patients which 30-50 years group and it was statistically significant (p=0,039). The pain mean at 12 hours postobturation pain in the CHX group which prepared with Resiproc system was found to be higher than ProTaper system and it was statistically significant (p=0,039). The result of the present study demonstrates that, different instrumentation techniques and the number of treatment appointments/ used medicaments type seem to have no influence on the postoperative pain severity and incidence of symptomatic with acute pain, multi-rooted vital teeth. The endodontic treatment preoperatively painful, symptomatic and vital teeth; when providing appropriate anesthesia, determining working lengths by a reliable method, completely chemomechanical preparation of the root canal, provide asepsis pain effectively reduce.
